The problem about settuping up the development Enviroment for OA

Question

Hi, All
     I just began to learn the development of OA Framework, I met the problem of setting up the dev environment by using jdevelop 9i OA
extension.
     The following is steps of setting up the env by referrring to the "Oracle Application Framework Developer's guide".
     1, set the environment variable JDEV_USER_HOME to <jdeveloper dir>\jdevhome\jdev
     2. copy the DBC file from <EBS install dir>\visappl\fnd\11.5.0.\secure in EBS server to the local machine.
     3. create a tester user and assign it the responsibility "OA Framework ToolBox Turtorial" and "OA Framework ToolBox Turtorial
Labs" in EBS
     4. create a database connection. set the connection type as Oracle(JDBC), username and password as "Apps" and "Apps" , Set the
hostname and SID the same values as those specified in the DBC file. And the connection is created successfully.
     5. Then open the toolbox.jws (The sample code in the jdeveloper9i)
          i) select the tutorial.jpr , select Project > Project Setting -> Runtime Connectiong. setting the "DBC File Name" to the
DBC file path in local machine. setting the "user name" and password to EBS user I just created in step 3. Set the Application Short Name
to "AK" and Responsibility Key as "FWK_TBX_TUTORIAL".
          ii) right click tutorial.jpr. select "Edit Business Components Poject..." -> Connection . choose the Connection created in step 4.
     6. setting the same configuration for LabSolutions.jpr.
     7. After all these setting , then rebuild the toolbox.jws and run the project. It took a long time to display the test_fwktutorial.jsp and when I click the link in it. I wil get an error page. The Detail Info is the following:
oracle.apps.fnd.framework.OAException: Application: FND, Message Name: FND_GENERIC_MESSAGE. Tokens: MESSAGE = oracle.adf.mds.exception.MDSRuntimeException; (Could not lookup message because there is no database connection) at oracle.apps.fnd.framework.OAException.wrapperException(OAException.java:888) at oracle.apps.fnd.framework.webui.OAPageErrorHandler.prepareException(OAPageErrorHandler.java:1145) at oracle.apps.fnd.framework.webui.OAPageBean.preparePage(OAPageBean.java:1960) at oracle.apps.fnd.framework.webui.OAPageBean.preparePage(OAPageBean.java:497) at oracle.apps.fnd.framework.webui.OAPageBean.preparePage(OAPageBean.java:418) at OA.jspService(OA.jsp:40) at com.orionserver.http.OrionHttpJspPage.service(OrionHttpJspPage.java:56) at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:317) at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:465) at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:379) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.evermind.server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:727) at com.evermind.server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:306) at com.evermind.server.http.ServletRequestDispatcher.forward(ServletRequestDispatcher.java:209) at com.evermind.server.http.GetParametersRequestDispatcher.forward(GetParametersRequestDispatcher.java:189) at com.evermind.server.http.EvermindPageContext.forward(EvermindPageContext.java:199) at OA.jspService(OA.jsp:45) at com.orionserver.http.OrionHttpJspPage.service(OrionHttpJspPage.java:56) at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:317) at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:465) at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:379) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.evermind.server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:727) at com.evermind.server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:306) at com.evermind.server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:767) at com.evermind.server.http.HttpRequestHandler.run(HttpRequestHandler.java:259) at com.evermind.server.http.HttpRequestHandler.run(HttpRequestHandler.java:106) at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:803) at java.lang.Thread.run(Thread.java:534)
