Problem:    

After upgrading from 10.1.3.1 to 10.1.3.4 OAS , 
an application (working fine in 10.1.3.1 ) is deployed into 10.1.3.4 oc4j .

The application is working well . 
But when invoking the DLLFileMonitor.jsp page ;

Then the following error occurs : 

JspServlet: unable to dispatch to requested page: Exception:oracle.jsp.parse.JspParseException: /jsp/dischargeloadlist/DLLFileMonitor.jsp: Line # 21, var url = '<html:rewrite action="/getFileErr"/>' Error: Attribute: action is not a valid attribute name

Symptoms:

As you can see the openFileErrs 
in the DLLFileMonitor.jsp file is called in : 
at line 214 : 

<c:choose>
<c:when test="${file.processStatus == 'R'}">
<display:column titleKey="dischargeloadlist.amend.fileErr" sortable="false" headerClass="tableHeader" 
class="tableRowDisplay" style="text-align:center">
<a href="javascript:openFileErrs('<bean:write name="file" property="fileRef"/>','<bean:write name="file" property="portCode"/>')"> ${file.fileErrCode}</a>
</display:column>
</c:when>
<c:otherwise>
<display:column property="fileErrCode" titleKey="dischargeloadlist.amend.fileErr" sortable="false" headerClass="tableHeader" 
class="tableRowDisplay" style="text-align:center"/>
</c:otherwise>
</c:choose>


Looking for this patern in the knowledge base , i have found : 
Bug 9349903 OJSPC FAILS TO TRANSLATE JSP CUSTOM TAGS

where there is a rediscovery information 

Rediscovery Information:
Problem 1
- Set req_time_introspection to init-param for JSP Servlet.
- Use name-from-attribute in a result.
- Use tag like this:
<c:choose>
<c:when test="${choosetest}">
<mo:FragmentTest resultName="result"/>
</c:when>
<c:otherwise>
<mo:FragmentTest2 resultName="result"/>
</c:otherwise>
</c:choose>
- 'result' may not be declared correctly and it fails to compile
generated java code.

Solution:

Bug 9349903 OJSPC FAILS TO TRANSLATE JSP CUSTOM TAGS

which occurs on 10.1.3.4 oc4j. 

One of the symptom of the bug is :
- Use tag like this:
<c:choose>
<c:when test="${choosetest}">
<mo:FragmentTest resultName="result"/>
</c:when>
<c:otherwise>
<mo:FragmentTest2 resultName="result"/>
</c:otherwise>
</c:choose>
- 'result' may not be declared correctly and it fails to compile
generated java code.
.

Which looks similar to the code in DLLFileMonitor.jsp .

1.       Apply the patch 9349903 
2. Undeploy the application ports.ear
3. Confirm there NO application folder for ports under ../j2ee/<OC4J_NAME>/application-deployments/ , if there please delete it.
4. Deploy the application again.
5. Retest the issue

2.       Remove Tags libraries which are deprecated.

used the following parameters which are depreciated
Old:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic"%>

Replace these lines with the following
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
