Jdev3.2,Jsp,BC4J, Data Tags : Unexpected exception Caught

Question

I wrote an jsp aplication, with data tags based on BC4J module.
when I run the application the first time, everything is Ok. the second Time an Unexpected exception is thrown.
the first module displayed in the error message is
msg=null oracle.jbo.ApplicationModule oracle.jbo.html.jsp.JSPApplicationRegistry.getAppModuleInstance(java.lang.String, javax.servlet.jsp.PageContext)
I thought that the problem is the module so
I runned the application module in the BC4J tester tool every thing is ok
I created a new aplication module but without any result.
I created a jsp Application based on the same application module but using the datawebbean and everything is ok also.
and here is a code that let the exception thrown.
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<jbo:ApplicationModule configname="test1.Test1Module.Test1ModuleLocal" id="Test1Module" username="wns" password="offline" />
<jbo:DataSource id="cat" appid="Test1Module" viewobject="TfixcategoryView" ></jbo:DataSource>
<select NAME="categoryList" size="10" multiple="yes">
<jbo:RowsetIterate datasource="cat" >
<option VALUE="<jbo:ShowValue datasource="cat" dataitem="Idcategory" ></jbo:ShowValue>"><jbo:ShowValue datasource="cat" dataitem="Dsnmcategory" ></jbo:ShowValue> </option>
</jbo:RowsetIterate>
</select>
can some help me to find a solution.

hi Juan
I didn't copy all the code source. but the releasepageresources tag is there. and I have only put this code because when I delete it no exception is thrown so the problem is there( in data tags).
more than this when this exception is thrown I have only to relog to a new windows 2000 session and no exception is thrown.
