I have a problem. I run EJB client by webstart at web, when initialized the context of properties, the exception is thrown, detail is:

Application server is:weblogic7.0, ejb and client is generated by Jbuilder9, the code of initialized the context is:

String url = "t3://jin:7001";
String user = "admin";
String password = "123";
Properties properties = null;
try {
properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, url);
if (user != null) {
properties.put(Context.SECURITY_PRINCIPAL, user);
properties.put(Context.SECURITY_CREDENTIALS, password == null ? "" : password);

return new InitialContext(properties);
catch(Exception e) {
log("Unable to connect to WebLogic server at " + url);
log("Please make sure that the server is running.");
throw e;

My jnlp file is:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://localhost:7001" href="webSt.jnlp">
<homepage href="webSt.html" />

<jar href="OwnerTest.jar" />
<jar href="Weblogic.jar" />
<jar href="WebServices.jar" />
<application-desc main-class="ownertest.OwnerTest" />

It is a security of problem, but I don't know how to resolve it.

I agree. Here's the link:
