EJB deployment problems

Question

I'm trying to deploy my business component as an EJB to Oracle 8.1.7. Actually, it deploys with no errors. When I test the module by setting the middle tier type to Local, it works fine. But, when I set the middle tier type to EJB, I can't see any data when I try to show my business component view.
So, I tried to deploy my applet and run it against the EJB, but I get an error in a Panic dialog box that says "Unknown service::session0". The details say
"DAC-405: SessionInfo:Application module creation failed; className: MyBcModule
Unknown service::session0
At the same time, the message view shows the following:
oracle.dacf.dataset.DataSourceOperationException: SessionInfo: Application module creation failed; className: MyBcModule
void oracle.dacf.dataset.ProducerObject.open(boolean)
void oracle.dacf.dataset.SessionInfo.publishSession()
void EISGui2.EISGuiApplet2.init()
void sun.applet.AppletPanel.run()
void java.lang.Thread.run()
The applet will run just fine when I set the session object to a local deployment type. I went through the trouble shooting stuff in the online help made sure my java_pool_size was set to at least 50MB, and that I have no unresolved java classes on the server. But, it still won't work. Are there any suggestions on what else I can try?

Answer 1

Of course, now I have other problems. After successfully redeploying my new business component as an EJB, and testing the application module successfully as an EJB middle tier server type, I created a new project as described in the online help under "Testing a Business Components EJB Deployed to Oracle8i with a Code Client." I followed the online help's instructions dilligently. Does it work? Of couse not. I'm turning on debugoutput with -Djbo.debugoutput=console so I can get more information, but that information isn't helping me. Refering back to the online help's code, it's crashing on the "ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(DeployedMod)" line. Here's my exception stack:
[00] Diagnostic Properties: Timing:false Functions:false Linecount:true Threshold:6
[01] CommonMessageBundle (language base) being initialized
[02] Stringmanager using default locale: 'null'
[03] BC4JDeployPlatform: Ejb

[05] Logging in...
javax.naming.NamingException: Unknown reasons. Root exception is

void oracle.jbo.client.remote.ejb.aurora.AuroraEJBAmHomeImpl.initRemoteHome()
void oracle.jbo.client.remote.ejb.aurora.AuroraEJBAmHomeImpl.<init>(oracle.jbo.JboContext, java.lang.String)
oracle.jbo.common.JboHome oracle.jbo.client.remote.ejb.aurora.AuroraEJBInitialContext.createJboHome(java.lang.String)

java.lang.Object javax.naming.InitialContext.lookup(java.lang.String)
void tester.EisBcTester.main(java.lang.String[])
Now, how can the EJB tester work, but my code can't find the helper class? I know my JNDI path is correct. I've checked to make sure that the EisBc.common.ejb.EisBcModuleHomeHelper class actually exists in the database and is valid. I've run java2perm.sql to grant permissions to my user. And, my java_pool_size is over 60MB.
This is frustrating. Did I see a thread about someone wanting to go back to VB...
