Symptoms

ClassNotFoundException is thrown when using same JPA cache with more than one app as below.
Added the below attributes in persistence.xml file to enable cache:

<properties>
<property name="openjpa.DataCache" value="true,true(Name=secondary-cache, CacheSize=100)"/>
<property name="openjpa.RemoteCommitProvider" value="sjvm" />
</properties>


This is working fine with one application.
Once we deploy second JPA application with above properties we are seeing below exception.
