initial context factory

[Josh Cimino]

I'm new to Websphere....

 

I think I've installed an ejb correctly. Now how do I connect to it? Should I use 'com.ibm.websphere.naming.WsnInitialContextFactory' as the initial context factory? What's the URL to connect to?

 

Also, does Websphere come with any sample source code? I can't seem to find any.

 

Thanks in advance,

localhost:900 which is the iiop port I believe

Here is a code snippet

 

 

try {

                       Properties props = new Properties();

                       props.put(Context.INITIAL_CONTEXT_FACTORY,                               "com.ibm.websphere.naming.WsnInitialContextFactory");

                       props.put(Context.PROVIDER_URL, "iiop://localhost:900");

                      

                       InitialContext _theCtx = new InitialContext(props);

                      

                       System.out.println("Got the initial context");

In addition you need the environemmnt, classpath etc setup correctly, I
cloned the dumpNameSpace script to run my external application which loaded
stuff into the websphere jndi context, also
beware that the websphere JNDI is not peristant in the basic websphere.

There are many samples delivered with websphere. Make sure that you
download
the full Info Centre and then go exploring. You need to visit the right
place in the
Info Centre in order to install the example code.

Also download the redbooks from www.redbooks.ibm.com

Also look at the articles on www.webspherepro.com

There is ample material in the above to get you going.

Should there also be the following line when getting an initial context?

 

props.put( Context.SECURITY_PRINCIPAL, "username" );
props.put( Context.SECURITY_CREDENTIALS, "password" );

 

Thanks,

When I try to get an initial context, I get the following error:

 

javax.naming.ServiceUnavailableException: NULL returned when resolving initial reference=NameService

 at com.ibm.ws.naming.util.WsnInitCtxFactory.getCosRootContext(WsnInitCtxFactory.java:452)

 at com.ibm.ws.naming.util.WsnInitCtxFactory.getRootJndiContext(WsnInitCtxFactory.java:337)

 at com.ibm.ws.naming.util.WsnInitCtxFactory.getInitialContext(WsnInitCtxFactory.java:200)

 at com.ibm.websphere.naming.WsnInitialContextFactory.getInitialContext(WsnInitialContextFactory.java:80)

 at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:665)

 at javax.naming.InitialContext.init(InitialContext.java:222)

 at javax.naming.InitialContext.<init>(InitialContext.java:198)

I'm assuming this is because the NameService is not enabled. So how do I enable the NameService?

 

Thanks,
