Hi,
I moved from Toplink Essentials to EclipseLink with Tomcat 6.0.18 and have this problem:
I created two web applications both uses EclipseLink. Due to using non-jta-datasources I created in both applications JPAEclipseLinkSessionCustomizer as shown here: http://wiki.eclipse.org/EclipseLink/Examples/JPA/Tomcat_Web_Tutorial
When I start one application everything works fine. As soon as I run the other application which uses EclipseLink I got exception:
Exception [EclipseLink-28014] (Eclipse Persistence Services - 1.1.1.v20090430-r4097): org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: Exception was thrown while processing property (eclipselink.session.customizer) with value (hlaseni.JPAEclipseLinkSessionCustomizer).
Internal Exception: java.lang.ClassCastException: hlaseni.JPAEclipseLinkSessionCustomizer cannot be cast to org.eclipse.persistence.config.SessionCustomizer
Can anyone help?
Thanks
