Documentation for installing license files issued for versions prior to 5.0 can be found here.

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:

    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 will be read from all locations defined by the environment variable, the Java system property and from the user's home directory.
    Example: -Dchemaxon.license.url="C:\ChemAxon\license2009.cxl;C:\ChemAxon\license2010.cxl"

  2. Automatic install:
    The license file is automatically recognized when stored in the .chemaxon (Unix) or chemaxon (Windows) sub-directory under the home directory of the user running the application. The following locations are accepted:

    • (.)chemaxon/license.cxl (file name is fixed)

    • (.)chemaxon/licenses/*.cxl (from version 5.3.2 only - the license file can have arbitrary name, the extension is fixed)

  3. Command line install:
    Launch the license shell script (Unix) or license.bat batch file (Windows) available in the Marvin Beans and JChem downloadable packages.
    Type license -h for the list of available options.

  4. Using Java API:
    chemaxon.license.LicenseManager.setLicenseFile(String path)
    chemaxon.license.LicenseManager.setLicense(String s)

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
