Installing Licenses on Servers

The possible ways of installing licenses on a server (web applications e.g. JSP pages, Pipeline Pilot):

1. Using system variables (recommended):
   The location of the license file can be set with:
   • CHEMAXON_LICENSE_URL environment variable (help on setting environment variables)
   • chemaxon.license.url Java system property
   From version 5.3.2 it is possible to define multiple license files of arbitrary locations. The separator character is ";".
   In case license files are set this way, the license files from the user's home directory will not be read unless the special word "default" is given.
   Example: -Dchemaxon.license.url="C:\ChemAxon\license2009.cxl;C:\ChemAxon\license2010.cxl;default"
2. Manual install:
   The license file must be stored on the server, in the .chemaxon (Unix) or chemaxon (Windows) sub-directory under the home directory of the user who started JChem Server. The following locations are accepted:
   • (.)chemaxon/license.cxl (the license file name is fix)
   • (.)chemaxon/licenses/*.cxl (from version 5.3.2 only - the license file can have arbitrary name, the extension is fix)
3. Command line install:
   Launch the license shell script (Unix) or license.bat batch file (Windows).
   Type license -h for the list of available options.
4. Using API:
   chemaxon.license.LicenseManager.setLicenseFile(String path)

If the licenses are installed later, when a web application is already running, it is not necessary to restart the web server (e.g. Tomcat), the License Manager will automatically and repeatedly check if a license file was installed in the meanwhile.

Licensing Applets

Example:

<script LANGUAGE="JavaScript1.1" SRC="../../../marvin.js"></script>
<script LANGUAGE="JavaScript1.1">
<!--
msketch_begin("../../..", 540, 480); // arguments: codebase, width, height
msketch_param("licenseFile", "https://www.yourserver.com/chemaxon/license.cxl");
msketch_end();
//-->
</script>

Restrictions:

• The licenses should have the "Server mode allowed" field
• The value should start with http:// or https://

Licensing via Java Web Start

Example:

  <property name="chemaxon.license.url" value="https://www.yourserver.com/chemaxon/license.cxl"/>
</resources>

Restrictions:

• The licenses should have the "Server mode allowed" field
• The value should start with http:// or https://
