Question

I am trying to perform a JNDI-lookup from within the GWT devmode.

I have a local glassfishv3 running the EJBs I want to look up. If i deploy the GWT-Webapp into said glassfish everything works as expected. But if I try to look up the EJBs from within devmode I get this Exception:

javax.naming.NamingException: Lookup failed for 'myBean' in SerialContext  [Root exception is javax.naming.NamingException: Unable to acquire SerialContextProvider for SerialContext  [Root exception is java.lang.NullPointerException]] ... Caused by: javax.naming.NamingException: Unable to acquire SerialContextProvider for SerialContext  [Root exception is java.lang.NullPointerException]
        at com.sun.enterprise.naming.impl.SerialContext.getProvider (SerialContext.java:276)
        at com.sun.enterprise.naming.impl.SerialContext.lookup (SerialContext.java:430)
        ... 22 more Caused by: java.lang.NullPointerException

        at com.sun.enterprise.naming.impl.SerialContext.getProvider (SerialContext.java:271)
        ... 23 more

It seems that the embedded jetty can’t find the class “SerialContextProvider” in the classpath.

I tried adding gf-client.jar and glassfish-naming.jar to the classpath (in addition to adding glassfish v3 to the target runtimes in eclipse), but to no avail.

I even put together a small sample (found here: http://satansoft.de/jnditest/jnditest.tgz) containing a simple EJB project as well as a GWT project that performs the lookup.
The archive also contains a small CLI client that works perfectly fine when run with gf-client.jar in the classpath.

I also asked this question on the official gwt mailing list, but nobody on there was able to help me.

So: has anybody been able to perform JNDI lookups from within GWT devmode into glassfish v3?

Add all jars from the Glassfish modules directory into the war/WEB-INF/lib directory of your Eclipse GWT project.
