embeddable EJB container of WebSphere 8 can not created - NoClassDefFoundError HpelHelper

Question

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:

Answer 1

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.

Answer 2

I was able to get rid of this problem was unchecking the runtime selection from project facets.

Also my config in JUint is as below

Map properties = new HashMap(); properties.put(EJBContainer.PROVIDER, "com.ibm.websphere.ejbcontainer.EmbeddableContainerProvider"); File jar = new File("./target/test_ejb.jar"); properties.put(EJBContainer.MODULES, jar); //DB properties configured in the embeddable container properties.put("com.ibm.websphere.embeddable.configFileName", "./target/test-classes/embeddable.properties"); EJBContainer ec = EJBContainer.createEJBContainer(properties);

Answer 3

I got this error as well when connecting to FileNet P8. I needed:

• com.ibm.ws.ejb.embeddableContainer_8.5.0.jar
• com.ibm.ws.ejb.thinclient_8.5.0.jar
• ibmorb.jar
• com.ibm.ws.emf.jar
• j2ee.jar
• Jace.jar
