Getting InitialContext to access datasource

[Sam Drake]

Hi,
I'm having trouble accessing a datasource from WSAD 5.0 in a stand-alone program. Please note that its a stand-alone program.
The code I use is as follows -
Hashtable Parms = new Hashtable();
Parms.put(Context.INITIAL_CONTEXT_FACTORY, AnalysisConstants.INITIAL_CONTEXT_FACTORY);
Parms.put(Context.PROVIDER_URL, "iiop://remotehost:2809");
InitialContext DBContext = new InitialContext(Parms);
DBSource = (DataSource) DBContext.lookup(strJNDIName);
....
But this is giving the following exception when I run it!
java.lang.IncompatibleClassChangeError: com.ibm.CORBA.iiop.ORB method createObjectURL(Ljava/lang/String Lcom/ibm/CORBA/iiop/ObjectURL;
at com.ibm.ws.naming.util.WsnInitCtxFactory.parseIiopUrl(WsnInitCtxFactory.java:1668)
at com.ibm.ws.naming.util.WsnInitCtxFactory.parseBootstrapURL(WsnInitCtxFactory.java:1427)
at com.ibm.ws.naming.util.WsnInitCtxFactory.getInitialContextInternal(WsnInitCtxFactory.java:368)
at com.ibm.ws.naming.util.WsnInitCtx.getContext(WsnInitCtx.java:102)

at com.ibm.ws.naming.util.WsnInitCtx.lookup(WsnInitCtx.java:131)
at javax.naming.InitialContext.lookup(InitialContext.java:359)
Please help.
Thnx,
Sam

Well, there are several problems here. First of all, you can't access InitialContexts or other things in a Standalone program and hope to make sense out of any of it -- it has to be a J2EE client program to make that work reasonably. Thus, your best solution is to create a J2EE client JAR file associated with an EAR project and do things that way.
However, the bigger problem you're going to run into is that even J2EE client programs don't have a well-defined way of accessing DataSources. This isn't going to work with WAS 5 datasources in any case. There is a way of doing this with WAS 4 datasources (see the infocenter) but it's not something you want to try to do.
Instead, STRONGLY consider doing the database update in an EJB and calling the EJB from your client program.
