Attempting to connect to EJB fails

Posted: Mar 20, 2003 9:45 AM

Hi--

I am writing an application that needs to access some EJBs for its functionality. I need to access the real EJBs rather than write stubs for integration tests. Can SuiteRunner do this? My first attempt yields exceptions.

Here is the relevant (I think) code:

Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
properties.put(Context.PROVIDER_URL, "localhost:1099");
properties.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");

InitialContext jndiContext = new InitialContext(properties);

Object ref = jndiContext.lookup("StringProcessor");

I get an exception raised on the call to jndiContext.lookup:
Test Failed
Name: AdminDBSuite.testGetUserList()
Message: javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException: com.javapro.ejb.StringProcessorHome (no security manager: RMI class loader disabled)]
Date: Thu Mar 20 11:30:53 EST 2003
Source: tests.AdminDBSuite@149a794
Thread: Thread-3
Throwable:
javax.naming.CommunicationException. Root exception is java.lang.ClassNotFoundException: com.javapro.ejb.StringProcessorHome (no security manager: RMI class loader disabled)
at sun.rmi.server.LoaderHandler.loadProxyClass(LoaderHandler.java:521)
<rest of the stack trace deleted for clarity>

Any ideas??

Thanks for your help!

The same code works great as an application.

When you start the JVM with no security manager installed, RMI won't load classes remotely. It looks like that's what your problem is.

I don't create a security manager in SuiteRunner, so you should be able to install one in your test code. For example, you could put this code in the constructor of your main Suite:

if (System.getSecurityManager() == null) {
     System.setSecurityManager(new RMISecurityManager());
}

You'll have to specify a policy file when you start SuiteRunner, as in:


java -Djava.security.policy=policy.all -jar suiterunner.jar myrecipe.srj

A nice tutorial on RMISecurityManager is here:

I haven't tried this. If you get this to work, please post again here.

Thanks.
