This document describes how to deploy the Java Web Start version of Instant JChem to your own server. This is relevant to administrators, not end users.
There are several potential reasons:
The Java Web Start version of Instant JChem can be deployed to a standard web server. Your users will run Instant JChem by launching it from a web page on that server.
You must have an IJC enterprise license to deploy to your own server using Java Web Start.
All the files you need are provided in a zip file that is located in the directory on the ChemAxon server that provides the publically available Java Web Start version of IJC. Download this file from here.
Unzip the files to the location on your web server that you want to deploy from. For illustration purposes we assume you have unzipped to a directory that called IJC that is accessed from your web server as http://myserver.mycompany.com/ijc
The file master.jnlp is the file that contains the JNLP deployment information. You MUST change the codebase definition on the second line so that it refers to the correct location on your web server. e.g. codebase="http://myserver.mycompany.com/ijc"
You can optionally edit the descriptions and icon if you want to change what your users see.
You may also edit the settings in the shortcut element. By default the online attribute is set to false to allow users to access the program when they don't have a network connection. But this means that users can potentially not get any updates immediately which can result in different versions being in use at the same time. If it makes no sense for your users to use IJC in offline mode (e.g. they will be using networked databases) then you are recommended to set this to true so that users will pick up updates immediately.
For other settings look at:
In this file edit the property "__ijc_version". This defines the
name of the directory that the IJC application is installed into as well as the
name of the user directory that contains the user's settings. By default this
is set to a value containing the version of IJC (e.g. 2.2.0). This would result
in new directories being used for each version, and users would loose all their
settings when this happened. This is generally a bad thing, so we recommend changing
this to a fixed value. The convention used for the publically available version is to
include the server name as part of this to ensure that versions and settings remain
distinct between different versions (e.g. one loaded from chemaxon.com and one from
your server). If you follow this convention you will use a value like this:
__ijc_version=myserver.mycompany.com_stable
but you can use any value you like here, but choose carefully.
When IJC launches these directories will be created in the .instantjchem directory which is located in the users home directory.
This is the web page from which your users will launch IJC. Edit this as you wish, but retain the link to the master.jnlp file that launches IJC.
Point your browser to http://myserver.mycompany.com/ijc/ and check it all works.
If you find problems or have any questions then please report them to the
IJC forum.
Updating the Java Web Start version
When an updated version of Instant JChem is available you will need to update your version. These are the steps:
Test the updated version to confirm that it meets your needs. You control the deployment to your server so you can make sure that the new version works the way you want prior to updating. You can test the Java Web Start version that is present at ChemAxon
Download the updated version file from here.
Unzip the contents of the zip file to a separate directory. You will need to make changes to the files before updating the contents of your server.
Modify the contents of the files as follows:
| File | Edit | Deploy |
|---|---|---|
| frame.gif | You can provide you own custom icon if you wish | No need to re-deploy this file unless it has been updated |
| index.html | You probably already have your own index.html so do not need this file | Keep you own index.html and not deploy this file |
| info.properties | You must edit this file to update the __ijc_version to the value
being used on your severer. e.g. in the example above:__ijc_version=myserver.mycompany.com_stable |
You must deploy this file |
| instantjchem.zip | Do not modify this file | You must deploy this file |
| JNLPInstaller.jar | Do not modify this file | You must deploy this file |
| master.jnlp | You may have customized this file when you first deployed. | Do not deploy this file, but do check for any changes that might improve your configuration. |
Update the appropriate files on your sever. See the comments in the previous section about which files should be deployed.
