Problem deploying Spring 3 app to Oracle Application Server - ClassCastException

[PaoloValladolid]

Has anyone succeeded in running a Spring 3.x webapp under pre-Weblogic Oracle Application Server or OC4J? Unfortunately our customer is using pre-Weblogic Oracle Application Server, so we have to test our Spring app on a similar setup. We are testing under OC4J 10.1.3.5.

Here is an excerpt of the stack trace we get upon any attempt to access the database. We do not get this error or other DB issues when running the same Spring app under Tomcat 6.x.

java.lang.ClassCastException: com.evermind[Oracle Containers for J2EE 10g (10.1.3.5.0) ].server.http.FileRequestDispatcher
	at com.evermind[Oracle Containers for J2EE 10g (10.1.3.5.0) ].server.http.EvermindHttpServletRequest.getAttribute(EvermindHttpServletRequest.java:3308)

This is the current Oracle datasource configuration in applicationContext.xml:

<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
   		<property name="connectionCachingEnabled" value="true" />
   		<property name="URL" value="${database.url}"/>
        <property name="user" value="${database.username}"/>
        <property name="password" value="${database.password}"/>
   		<property name="connectionCacheProperties">
      		<props merge="default">
         		<prop key="MinLimit">3</prop>
         		<prop key="MaxLimit">20</prop>
      		</props>
   		</property>
	</bean>

The exception stack trace is generated when the server tries to compile the Spring 3.x MVC framework/JSPX code from JSPX to HTML. Currently, it compiles the following

<form:form commandName="myDeliveryPackage">
    	<table>
			<tr>
				<td>
						<table>
							<tr>
								<td><input type="submit" value="New"/></td>
								<td> or </td>
								<td><form:input path="packageNumber" /><input type="submit" value="Enter package number to edit" size="30"/></td>
							</tr>
						</table>
				</td>
			</tr>
		</table>	
	</form:form>

into the following under OC4J:

<form id="myDeliveryPackage" action="/IDS/WEB-INF/layouts/ids-default.jspx?form=t" method="post"><table><tr><td><table><tr><td><input type="submit" value="New"/></td><td> or </td><td><input id="packageNumber" name="packageNumber" type="text" value=""/><input type="submit" value="Enter package number to edit" size="30"/></td></tr></table></td></tr></table></form>

Under Tomcat 6.0, the Spring/JSPX code compiles into this, which is correct:

<form id="incidentPackage" action="/IDS/myDeliveryPackages?form=t" method="post"><table><tr><td><table><tr><td><input value="New" type="submit"/></td><td> or </td><td><input id="packageNumber" name="packageNumber" type="text" value=""/><input size="30" value="Enter package number to edit" type="submit"/></td></tr></table></td></tr></table></form>

I am at a loss as to why this is happening. I just know that the exception has something to do with the inability to find a certain attribute to generate the correct action URL.

I forgot to include some config files:

Bolded line above is the one not being converted by Oracle Application Server to the proper URL under WEB-INF/views.

The customer is now insisting that this issue be resolved, even though the overall operation of the web application is not affected by these ClassCastExceptions.
