'''Jmol-JSO''' (new in Jmol v.13) provides a clean, efficient way to interact with the Jmol applet from JavaScript and, in addition, allows extension to Java- and applet-challenged platforms such as the iPad, the iPhone, and Android mobile devices, and adds easy access to public databases such as [http://rcsb.org the RCSB PDB database], [http://cactus.nci.nih.gov/ the National Cancer Institute CACTVS server], and [http://pubchem.ncbi.nlm.nih.gov/ PubChem], even when the Jmol Java applet is not available because of a user's platform. Basic high-level scripting for these non-Java alternatives is included. In addition, '''Jmol-JSO''' adds synchronization with the [http://jspecview.sourceforge.net JSpecView applet] and 2D-to-3D model building and interconversion using the [http://www.molinspiration.com/jme JME applet]. See more details on [[Jmol JavaScript Object]].

==== The Jmol.js library ====
 
−
For Jmol 12 (and Jmol 13, if desired), the '''Jmol.js''' library provides a set of simple scripting commands that allow rapid construction of web pages that include user interactivity such as buttons, checkboxes, links, and menus. Note that all functions in Jmol.js have been implemented with counterparts in '''Jmol-JSO'''. For an overview of these functions, see the [{{Website}}jslibrary/ Jmol.js online documentation] or, for the most up-to-date info, just browse the Jmol.js source file.
 
−
 
 
−
''Note:'' {{file|Jmol.js}} '''is phased out''' in Jmol v.13, in favour of the new set of object-oriented JavaScript method and {{file|.js}} files (described next).
 
−
Also, '''the download''' for Jmol version 13.2 or later '''does not include this file'''. If you still want to use it, you can get it individually from the [{{SVN Trunk}}Jmol/appletweb/old/Jmol.js Jmol repository]. Particularly, '''new security policies that are being enforced in Java will make the old versions of {{file|Jmol.js}} nonfunctional''' starting January 2014. (From then on, the code for inserting the applet in the webpage must declare some permissions attribute.) If you cannot switch your website to [[Jmol_JavaScript_Object|using Jmol-JSO]] or using [[Jmol_JavaScript_Object#Conversion_using_the_Jmol2.js_.27adapter.27_library|the transitional adapter Jmol2.js]], you should start substituting your existing Jmol.js file with the updated Jmol.js ([{{SVN Trunk}}Jmol/appletweb/old/Jmol.js?format=raw download]).

=== Jmol Applet JAR files ===
 
−
Regardless of which JavaScript library is used, Jmol-JSO or Jmol.js, there are four different ways to implement Jmol as an applet:
 
−
 
 
−
* '''Monolithic unsigned applet''' You can include {{file|JmolApplet.jar}} on your web site and just use that. If using Jmol.js, the applet will only have access to files on your site; if using Jmol-JSO, the applet will have access to files on your site as well as files at public databases.
 
−
 
 
−
* '''Modular unsigned applet''' You can include {{file|JmolApplet0.jar}} and related files (54 {{file|jar}} files total) on your site. Although a large number of files, the advantage of the modular applet is that only those parts of Jmol that are necessary are downloaded by the user's browser initially, and additional components are transferred only as needed. This allows the applet to load much faster.
 
−
 
 
−
* '''Monolithic signed applet''' {{file|JmolAppletSigned.jar}} is a large (2.5+ MB) single file that includes all of Jmol in the form of a signed applet. The signed applet has substantially more capability, including full cross-domain file access and the capability to transfer files to and from the user's hard drive.
 
−
 
 
−
* '''Modular signed applet''' {{file|JmolAppletSigned0.jar}} and related files, like JmolApplet0.jar, allows modular as-needed transfer of files from your site to the user's browser. This is the preferred method of using the signed applet.
 
−
 
 
−
=== Giving the Jmol applet more memory to work with ===
 
  
−
Note: This can now be done using Jmol.js (<code>jmolSetMemoryMb(nMb)</code>) or Jmol-JSO (Info.memoryLimit = nMb).
+
====  Forcing the JSmol object to open in a certain language ====
−
 
+
The JSmol object includes [[Internationalisation/Current_Status|several languages]] (technically called localizations) for the user interface (pop-up menu). JSmol will open by default with the interface using the language of your operating system
−
Memory available to Jmol is determined by Java. You can check the current memory allocation by opening the pop-up menu in the applet, and the last submenu "About Jmol".
 
−
 
 
−
Less or more memory can be allocated by using this parameter:
 
−
-Xmx###M
 
−
where the ### must be substituted by a number in megabytes (hence the "M" after it). However, the amount of memory that can be allocated is limited by your existing RAM. For example, on a system with 512 MB RAM, a maximum of 256 MB is allowed for Java.
 
−
 
 
−
Examples:
 
−
* -Xmx512M  will give 512 Mb maximum memory available.
 
−
* -Xmx1024M    will give 1024 Mb maximum memory available.
 
−
 
 
−
The place to set this parameter depends upon your system:
 
−
 
 
−
====Windows====
 
−
*Control Panel > Java icon (opens the [[Solving_Java_Problems#Java_Control_Panel|Java Control Panel]]) > "Java" tab > "Applet run-time configuration" > "Show" button > on row "JRE" (latest version if there are several), click on the textbox under "Parameters" and type: -Xmx###M
 
−
 
 
−
====Macintosh====
 
−
* OS 10.5 (Leopard): Double click on JavaPreferences.app (in /Applications/Utilities). In the 'General' tab, select the first version of Java that is in the list. This will activate the 'Options' button: click it. A box for 'Applet Runtime Parameters' will open, where you can enter the -Xmx###M parameter.
 
−
* OS 10.4 (Tiger): Possibly look under /Applications/Utilities/Java/J2SE 5.0/Java Preferences, then look for the place to put the -Xmx###M
 
−
*Or look in the [[Solving_Java_Problems#Java_Control_Panel|Java Control Panel]].
 
−
 
 
−
Note that this is a local setting, so it will only affect that computer. You cannot expect that visitors of your web pages will have the same Java memory configuration as you, so be careful when using this feature.
 
−
 
 
−
Technical details:
 
−
* -Xmx sets the maximum memory heap size.
 
−
* -Xms sets the minimum memory heap size.

===  Forcing the JSmol object to open in a certain language ===
 
−
The JSmol object (both Java and HTML5 modalities) includes [[Internationalisation/Current_Status|several languages]] (technically called localizations) for the user interface (pop-up menu). JSmol will open by default with the interface using the language of your operating system

[[File:Java_Warning_Signed.png|right|231px]]
 
−
The '''signed''' applet can load a molecular model from any http or ftp URL. However, the user will be asked to trust the signed applet (figure at right). This could be problematic since the publishing authority (jmol.org) "cannot be verified", and the security certificate was issued by a group that is "not trusted" (jmol.org). This is because it would be costly and cumbersome for each version of the applet to be signed by a trusted (commercial) authority.
 
−
 
−
The '''unsigned''' applet displays the molecule without asking the user to trust it. However, it is limited (for security reasons) to loading molecular models from the same http domain (server) that downloads the applet itself. [http://firstglance.jmol.org/ FirstGlance in Jmol] uses the unsigned applet by default, but the signed applet will be used when that "Advanced Option" is checked. Thus you can easily see both applets in action. Methods for accessing data files from arbitrary servers are described in some detail at [http://bioinformatics.org/firstglance/fgij/datameth.htm PDB Data File Access Methods].
 
−
<br>
 
−
If you are ''not'' running the applet from any server, i.e., you are using a web page residing in a '''local disk''', further security restrictions are applied by Java: molecular models can only be located in the same folder/directory as the applet files or below it; read [[Jmol Applet Deployment Local]].

==Setting up a Jmol site in The Cloud, in an AWS S3 bucket==
 
−
 
 
−
Oct 2013: This section describes how to set up a simple Jmol demonstration site in an
 
−
S3 bucket. In passing it also confirms a working layout of JmolAppletxxx
 
−
files, html files, model files as described above. Note this is purely for the Java version of Jmol, not JSmol.
 
−
 
 
−
AWS S3 (Amazon Web Services, Simple Storage Service) is ideal for setting up a simple
 
−
demonstration Jmol site with embedded applets.
 
−
 
 
−
S3 provides reliable, cheap cloud storage, with a default web access service.
 
−
Costs are negligible for a small site: http://aws.amazon.com/s3/pricing/  Also you get 12 months useful access
 
−
free with the AWS Free Usage Tier. This gets around the many headaches of using web servers on
 
−
institutional computers.
 
−
 
 
−
Example of S3 bucket used as Proteomics data archive, for academic paper Supplementary Information:

−
You probably already have an Amazon account for book purchase.
 
−
If not, https://www.amazon.com  and navigate to New Account.
 
−
Then go to http://aws.amazon.com/console/  and sign in. Go to the S3 Console by clicking on "S3 Scalable Storage In The Cloud", or select S3 from the Services menu
 
−
at the top left.
 
−
 
 
−
Create a bucket. Bucket names are unique across all the AWS data centres, so
 
−
obvious ones like "test" or "mybucket" will already be taken. The bucket will
 
−
be accessible at the base address http://bucketname.s3.amazonaws.com
 
−
It will also be accessible via http://s3.amazonaws.com/bucketname/
 
−
 
 
−
The S3 Console provides simple facilites to create buckets, and folders and
 
−
subfolders within them, and upload/download files, and also to set file permissions and Mime file types,
 
−
and other general filesystem admin (rename, delete, cut/copy/paste etc). There are other methods such as
 
−
commandline tools, and Gui-based apps (see below) which allow more streamlined control for large numbers of files or repetitive tasks.

In the bucket, all files should generally have Public Access permissions. HTML files should have type text/html, images should have type image/png etc. If these do not set themselves automatically during your file upload, they can be corrected in the S3 Properties - Permissions/Metadata gui. Note it is easy to lose these settings when re-uploading a new version of a file.

Note: although the title of this page remains the same, there is no longer any implication of Java applets involved in running Jmol

Running Jmol / JSmol

Jmol HTML5 Object (JSmol)

This allows Jmol to be embedded in web pages. Like with the application, commands can be applied to the model using the Scripting language. For some demonstration pages see http://jmol.sourceforge.net/demo/. To see the HTML source use your web browser View → Page Source. Starting with version 13.1, Jmol may also be inserted into web pages using the non-Java alternative, called JSmol. This allows to use an HTML5 object that only requires JavaScript and has the same set of features as Jmol applet. See Jmol JavaScript Object for more details.

Installing Jmol objects

Installing Jmol / JSmol

If you only wish to create a web page(s) containing molecular scenes in Jmol, there are easier ways than starting from scratch: see #Tools for Authoring Jmol Web Pages. If you wish to learn how to create web pages containing Jmol from scratch, read on.

Download the Jmol package (either .zip or tar.gz format) and extract/uncompress only the necessary files to the folder of your choice.

Which are those necessary files? Read subsections below.

To use the Jmol object within local web pages, e.g. on the hard disk or on CD, see Jmol Applet Deployment Local for some precautions needed.

For some specific needs, you must use other files; read the sections below about the signed applet.

If you distribute your web page files, you should also include the copyright, license and information files: File icon.gifCOPYRIGHT.txt, File icon.gifLICENSE.txt and File icon.gifREADME.txt

Inserting Jmol objects into web pages

Inclusion of Jmol objects and interaction with them are managed easily using a JavaScript-based solution:

Jmol JavaScript Object (Jmol-JSO)

Jmol-JSO (new in Jmol v.13) provides a clean, efficient way to interact with the Jmol applet from JavaScript and, in addition, allows extension to Java- and applet-challenged platforms such as the iPad, the iPhone, and Android mobile devices, and adds easy access to public databases such as the RCSB PDB database, the National Cancer Institute CACTVS server, and PubChem, even when the Jmol Java applet is not available because of a user's platform. Basic high-level scripting for these non-Java alternatives is included. In addition, Jmol-JSO adds synchronization with the JSpecView applet and 2D-to-3D model building and interconversion using the JSME Molecule Editor. See more details on Jmol JavaScript Object.

Forcing the JSmol object to open in a certain language

The JSmol object includes several languages (technically called localizations) for the user interface (pop-up menu). JSmol will open by default with the interface using the language of your operating system (ref.). However, if you need to change this:

  1. The language in JSmol can be switched anytime, from the pop-up menu, "Language" item near the bottom.
  2. Or, using the scripting language: language = "de" (you must use the keyword "language" and the two-letter language code: ca, cs, de, en, es, et, fr, nl, pt, tr, etc.). In a few cases, the language code has 2+2 letters: en_GB, en_US, pt_BR, zh_CN, zh_TW
  3. To set the language just when the JSmol object is created as the web page loads, use the language parameter of the Info variable.

Testing different JSmol versions

(This is an advanced feature)

You can force the use of a certain version of JSmol object in any web page (even if that page is not yours), as long as the page was written using the standard, recommended code for inserting JSmol objects. The way to do so is:

On the URL line of the browser, add the following:

?_J2S= followed by the url of the Folder icon.gifj2s folder your intend to use. Note: uppercase is needed for the part before =

If there is already a ? in the URL, then use & for your addition, to preserve the logic of a url.

This may work or not, depending on the page code and on the JSmol versions.

Jmol in Wikis

The applet can be embedded in HTML (or XHTML) pages (examples are listed on Websites Using Jmol), but also, with some extra technologies, in Wiki pages (see Jmol Processor).

Tools for Authoring Jmol Web Pages

Jmol.php: easy Jmol insertion into a web page

You can insert a Jmol object into a web page with nothing more than a simple <script> or <a> tag. You don't have to install any Jmol files in your computer or web server. You don't even need a file with the 3D model; it will be automatically obtained from an appropriate web server.

Note that this way of using Jmol is easily compatible with any environment where you do not control the full source code, like forums, blogs, wikis, content management systems, e-learning environments... In fact, you can email the address and the recipient will see the Jmol object by clicking on the received link.

See Jmol_PHP for details.

Proteopedia's Scene Authoring Tools

The easiest way to create, and share, a web page containing customized molecular scenes in Jmol, is to build the page in Proteopedia.Org. Proteopedia's Molecular Scene-Authoring Tools free you from learning any Jmol commands, HTML, or javascript. You will only need to learn a tiny bit of wikitext markup, for which convenience buttons and help are provided. On the other hand, if you already know some Jmol commands, you may use them in creating your scene (via the Jmol console). Regardless of how your scene is created, it will be saved as a Jmol state script. You may upload atomic coordinate files, or use published PDB files. Proteopedia automatically saves a frozen copy of each PDB file that you use, to protect your scripts from breaking e.g. after remediation of files by the Protein Data Bank. You may created pages that are protected from editing by others.

Jmol's Export to Web

If you are not comfortable writing html/xhtml and javascript code, or would just like to quickly put together some simple pages, then look at the export to web function of Jmol. This allows you to export all the necessary files to make simple pages that have a number of live Jmol displays or a single Jmol display that can be changed by clicking buttons. You select the views you want the user to see by setting them up in Jmol. You then add any desired text or comments to the .html file created by the export function in your favorite web editor (Some open source suggestions: SeaMonkey is simple and works very well, Kompozer is more sophisticated and works pretty well, Amaya is the most sophisticated but is harder to use). Instructions for using the export function are accessible in the export to web dialog within the Jmol application. A more detailed tutorial and some older packages are available at Jmol Web Page Maker.

Saving Files from the Jmol Object

Although this isn't obvious, the molecule that is being shown in JSmol can be saved to local disk unless the model was loaded inline, in which case this technique fails. To do so:

  1. Open the applet's menu (right-click, Ctrl+click, or click on bottom-right "Jmol" logo).
  2. Click on the last entry (About...).
  3. On the submenu that appears, the first entry is the name of the first model loaded. If it says "string" then the model was loaded inline and continuing will result in a "404" resource not found error. If the entry is a file name, then you can continue. If more than one file has been loaded, there will be a line for each on this submenu. Click on the one that you want to open or save. This will bring up another layer of menu options
  4. Click on the last entry (View + name of file)
  5. Depending on your browser's configuration, the file will be opened in the associated program ("helper application") or you will get an "Open or Save" dialog; choose Save and location in your disk.
Warning: At least in Windows, modern browsers may detect this action as opening a pop-up window, so it's likely that the pop-up blocker will prevent you from seeing the "Open or Save" dialog. Pay attention to messages and options in your browser to allow pop-ups for the current page. (Such messages often appear as yellow bars at the top of the page, warnings in a toolbar, or hints in the status line at the bottom of the browser window.)

In addition to saving the full model, a part of the molecule can be extracted and saved into MOL format. This is not so straightforward as the former, and is described in the "interactive scripting documentation" (see Jmol home page).

It is also possible to save the state of the molecule (rendering style, coloring, visibility, orientation, etc.). See save state and write state in the Jmol scripting documentation.
