Due to US government export restrictions, JVM implementations are delivered with a restricted cryptographic strength that varies depending on the Java Virtual Machine vendor.
Because FEX products rely heavily on the cryptographic capabilities of the underlying JVM, there may be problems running with lower cryptographic constraints, ranging from non support of certain required key lengths, to not being able to start.
To solve this, the Java Virtual Machine must be modified to include the Java Unrestricted Jurisdiction Policies. These policies are usually shipped as a ZIP file that you use to overwrite the files local_policy.jar and US_export_policy.jar, located in the $JAVA_HOME/lib/security directory.
These policies are included with the delivered Java version of the Axway installer.
Important: If you are using WebSphere you must copy the policy files to the lib/security directory of the WebSphere Java location (this is the JAVA_HOME of the WebSphere Application Server).
