Binding a DataSource to JNDI

Question

I am trying to use MockRunner's mock DataSources with Weblogic 8.5. I need to bind the DataSource to Weblogic's JNDI to make it available to the application:
MockDataSource ds;
context.rebind("MyDataSource", ds);
But rebind() throws this exception:
testMain(com.demo.tests.jdbc.Mock)javax.naming.NamingException: Unhandled exception in rebind() [Root exception is java.lang.IllegalArgumentException: Object must be a CORBA object: com.mockrunner.mock.jdbc.MockDataSource@7f4ec]
     at weblogic.corba.j2ee.naming.Utils.wrapNamingException(Utils.java:81)
     at weblogic.corba.j2ee.naming.ContextImpl.rebind(ContextImpl.java:340)
     at weblogic.corba.j2ee.naming.ContextImpl.rebind(ContextImpl.java:300)
     at javax.naming.InitialContext.rebind(Unknown Source)
Strangely binding <i>java.lang.String</i>s do work.
I have also tried to bind <i>org.apache.commons.dbcp.PoolingDataSource</i>, and it fails with the same error as with <i>MockDataSource</i>.

Here is the whole piece of code. I need the program to be a standalone Java program. wlclient.jar is in the classpath.
It works when binding strings and looking up existing objects registered to JNDI.
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.mockrunner.mock.jdbc.JDBCMockObjectFactory;
import com.mockrunner.mock.jdbc.MockDataSource;
JDBCMockObjectFactory factory = getJDBCMockObjectFactory();
MockDataSource ds = factory.getMockDataSource();
Properties env = new Properties();
env.put( Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory" );
env.put( Context.PROVIDER_URL, "t3://localhost:7001" );
InitialContext context = new InitialContext(env);
context.rebind("MockDataSource", ds);
