Weblogic 12c and EmbeddedContainer

Question

Hi,
I have installed new Weblogc Server 12.1.1. Now I'm trying to start the embedded container in a test case. My classpath contains the wlfullclient.jar.
But I'm getting an exception during startup:
javax.ejb.EJBException: Error instantiating embedded server

@Test

Can anybody help me?
Thanks.

Sort of tested this as well and encountered the same problem. The enterprise bean looks as follows:
package model.logic;
import model.entities.Person;
import javax.ejb.Local;
@Local
public interface Company {
    public void insertPerson(Person person);
    public void removePerson(Integer sofinummer);
    public void updatePerson(Person person);
}with the implementation
package model.logic;
import model.entities.Person;
import javax.ejb.Stateless;
@Stateless(name = "Company", mappedName = "Company")
public class CompanyBean implements Company {
    public void insertPerson(Person person) {
        System.out.println("insert " + person);
    public void removePerson(Integer sofinummer) {
        System.out.println("remove " + sofinummer);
    public void updatePerson(Person person) {
        System.out.println("update " + person);
}To test the embedded EJB container the following is used
package test;
import model.logic.Company;
import javax.ejb.embeddable.EJBContainer;
import javax.naming.Context;
import javax.naming.NamingException;
import java.io.File;
import java.util.HashMap;
import java.util.Map;
public class Test {
    public static void main(String[] args) {
        Map properties = new HashMap();
        File module = new File("C:\\temp\\frameworks\\Model\\out\\artifacts\\Model\\Model.jar");
        properties.put(EJBContainer.MODULES, module);
        properties.put(EJBContainer.PROVIDER, "weblogic.ejb.embeddable.EJBContainerProvider");
        System.out.println("testing some stuff");
        EJBContainer container = EJBContainer.createEJBContainer(properties);
        Context context = container.getContext();
        try {
            Company company = (Company) context.lookup("java:module/Company");
            company.removePerson(12345);
        } catch (NamingException e) {
            e.printStackTrace();
        container.close();
}To run the test (after compiling and packaging the different projects in jars) we use the following shell script
set JAVA_HOME=C:\bea\jdk1.6.0_35
set MEM_ARGS=-server -Xms512m -Xmx512m -XX:NewRatio=2 -XX:+UseParallelGC -XX:ParallelGCThreads=2 -XX:MaxGCPauseMillis=200 -XX:GCTimeRatio=19 -XX:+UseParallelOldGC
set CLASSPATH=C:\temp\frameworks\Model\out\artifacts\Model\Model.jar;C:\temp\frameworks\EmbeddedEJB\lib\wlfullclient.jar;C:\temp\frameworks\EmbeddedEJB\out\artifacts\Runner\Runner.jar
%JAVA_HOME%\bin\java %MEM_ARGS% test.TestThe wlfullclient.jar (for version 12.1.1.0) is build by using the instructions presented here: http://docs.oracle.com/cd/E17904_01/web.1111/e13717/jarbuilder.htm#BABCGHFH
When the test is run the following is observed:
C:\temp>run.cmd
C:\temp>set JAVA_HOME=C:\bea\jdk1.6.0_35
C:\temp>set MEM_ARGS=-server -Xms512m -Xmx512m -XX:NewRatio=2 -XX:+UseParallelGC -XX:ParallelGCThreads=2 -XX:MaxGCPauseMillis=200 -XX:GCTimeRatio=19 -XX:+UseParallelOldGC
C:\temp>set CLASSPATH=C:\temp\frameworks\Model\out\artifacts\Model\Model.jar;C:\temp\frameworks\EmbeddedEJB\lib\wlfullclient.jar;C:\temp\frameworks\EmbeddedEJB\out\artifacts\Runner\Runner.jar
C:\temp>C:\bea\jdk1.6.0_35\bin\java -server -Xms512m -Xmx512m -XX:NewRatio=2 -XX:+UseParallelGC -XX:ParallelGCThreads=2 -XX:MaxGCPauseMillis=200 -XX:GCTimeRatio=19 -XX:+UseParallelOldGC test.Test
