How to get ride of `com.pentaho.commons.dsc.f: license missing, invalid, or expired?`

I made a Transform to send JMS Produce to ActiveMQ.

but during executing the transform via my Java Client Application including PDI Jars.

I faced this Error :

2014/08/10 13:06:54 - ACTIVEMQ - Dispatching started for transformation [ACTIVEM
Q]
Exception in thread "Thread-8" com.pentaho.commons.dsc.f: license missing, inval
id, or expired
        at com.pentaho.commons.dsc.j.a(SourceFile:92)
        at org.pentaho.di.trans.steps.jms.f.<init>(SourceFile:61)

        at org.pentaho.di.trans.Trans.prepareExecution(Trans.java:891)
        at org.pentaho.di.trans.Trans.execute(Trans.java:604)

I tried to use the license file that installed with Pentaho called .installedLicenses.xml but no effect!

I know that Pentaho is under Full Free License, so what's the problem and what do I do?

Solution

The problem is that the plugin you're trying to use is an Enterprise Edition plugin and requires a valid license to run.

When you download the trial version you get a 30 day license.
