JBO30003 while executing ADF Application Module WebService

Question

Hi all,
I'm using JDev 10.1.2.0 build (1913), Application Server 10g (9.0.4.0.0), Database 10g (10.2.0.1), All of them runs on Windows XP box. Currently, I'm developing a Web Service application from my existing J2EE application. The existing J2EE application uses ADF (client and server side), SpringFramework RCP (client for menu framework)+Swing. It was compiled and run succesfully. Client can connect to application server, accessing EJB, database.
The problem occurs when I try to make another deployment that support WebService. We know that with JDev, we can easily create WS App from EJB. Since my EJBs are statefull--which cant be use for WS--I try to make WS from Application Module, by simply drag J2EE WebService in Remote App Module Dialog Box. The WSDL is created, Interface is created too.
For deployment to AS, i'm using ant because JDev can't create EAR file with proper library. I've done this:
1. copying snippet code web.xml from JDev generation to my web.xml, starting from Servlet tag until servlet mapping.
2. include wsdl file for my JAR file
3. deploy to AS with Enterprise Manager
The WS End Points can be access from http browser. All of methods are accessible. But when I'm invoking any random method, the result is always like this:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<faultcode>SOAP-ENV:Server.Exception:</faultcode>
<faultstring>oracle.jbo.common.ampool.ApplicationPoolException: JBO-30003: The
application pool (xxx.xxx.xxxxxx.model.service.SOSAAppModuleLocal) failed to
checkout an application module due to the following exception:</faultstring>
<faultactor>/serverpoc/AppModuleService</faultactor>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>is there some XMLs snipped code from JDev's WS generated file that i'm not put them in my ant's XMLs? because i'm sure that all of my EJBs in same EAR file with WS application are accessible from ADF Swing Client
i'm googling the error message JBO-30003, but none of them fits my problem. Any help and suggestions are appreciated. Thanks...

Answer 1

i notice that there is file Webservice.deploy. What is it for? I assume that file is used by some kind of proccess of JDev to deploy EAR file.If it is a compulsory file, how to convert it to ANT build file?
I've modified some classes in my working J2EE application, and deploy it with JDev to my AppServer. But still, while invoking anymethods of WebService at my endpoint, it also has same XML response that an error occured with JBO-30003..
Having searched in oracle, i found examples are using JDev 10.1.3 which is completely different with my JDev 10.1.2 (build 1913). I cant follow that tutorial. Any one know how to deal with this issues?
Thanks
