I am using the embeddable EJB container of WebSphere 8 to write some unit tests for my EJBs with JUnit4. My IDE is the RAD 8.

Here is my simple test code snippet:

 

    Map properties = new HashMap();
    properties.put(EJBContainer.PROVIDER,
                "com.ibm.websphere.ejbcontainer.EmbeddableContainerProvider");
    EJBContainer ec = EJBContainer.createEJBContainer(properties);

I get a NoClassDefFoundError:

The RAS included in the WebSphere embeddable EJB container does not use HPEL. This error message implies that some JAR on your classpath is using a different RAS. You should remove all WebSphere JARs except C:\Program Files\IBM\WebSphere\AppServer\runtimes\com.ibm.ws.ejb.embeddableContainer_8.0.0.‌​jar.
