License

Default License Loading Path

ZSS loads a license file from the default path WEB-INF/classes/metainfo/zss/license. If the license is loaded successfully, you should see some license information printed on your application console like:

*** Potix Corporation License Information ***
(your license information)

Specify Loading Path with a Library Property

Some application servers like Weblogic could fail to locate the license file in the default path. You shall put the following library property in zk.xml to specify the license directory and copy your ZSS license file there.

<library-property>
    <name>org.zkoss.zssex.rt.Runtime.directory</name>
    <value>c:/my-directory/my-licenses</value>
</library-property>

Specify the Path in a System Property

Because Library.getProperty() will look for a system property if no corresponding property defined in zk.xml, you can also pass the license file path to ZSS via a system property.

For example in a Tomcat, you can add a setenv.sh (or setenv.bat) that contains

export CATALINA_OPTS="$CATALINA_OPTS -Dorg.zkoss.zssex.rt.Runtime.directory=/yourLicenseFilePath/onThisServer"

Tomcat catalina.sh will invoke this script if exists.

Refer to your application server's documentation to set a system property. In conclusion, you can pass the path in any way that can be retrieved by Java's System.gerProperty(), e.g. a system variable in Windows.
