Struts 1.2.9 on OC4J 10.1.2 Not working

Asked by MehtaJasmin in Oracle IAS Application Server

Tags: ,

Hi All,

I have been trying all sort of different things to deploy my .ear file on OC4J that has struts used in .war file. The same .ear file deploys correctly and works fine on runtime for my Standalone OC4J10.1.2 on windows but when I try to deploy it on UNIX box for Standalone OC4J10.1.2 it does deploy right but it breaks runtime on access to login.jsp as soon as it finds the first struts tag.

Pl help me asap. I have no idea, if this version of struts is not supported by this version of OC4J or what?

Here is the config for web.xml
------------------------------------------

<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>application</param-name>
<param-value>ApplicationResources</param-value>
</init-param>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>2</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
---------------------------------------------------------------------------
My all struts related jars are located at WEB-INF/lib

commons-fileupload.jar
commons-logging.jar
commons-digester.jar
commons-beanutils.jar
commons-validator.jar
jakarta-oro.jar
antlr.jar
struts.jar

I am not specifying any classpath as the server should pick up libraries from WEB-INF/lib.

Here is my login.jsp
----------------------------

<%@ page contentType="text/html;charset=windows-1252"%>

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

</style>

<body>
<table>

</td>
<td> </td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
<html:form action="Login" onsubmit="return validateLoginForm(this);">

value="Log In"
onmouseover="javascript:goLite(this)"
onmouseout="javascript:goDim(this)"
/>

</html:form>
</td>
</tr>
</table>
</body>
</html>
-------------------------------

It breaks at line
@import url(<html:rewrite page="/COES/css/coes.css" />);
and on browser I see err

java.lang.NullPointerException at org.apache.struts.taglib.TagUtils.pageURL(TagUtils.java:1070) at org.apache.struts.taglib.TagUtils.computeURLWithCharEncoding(TagUtils.java:449) at org.apache.struts.taglib.html.RewriteTag.doStartTag(RewriteTag.java:55) at _jsp._login._jspService(_login.java:51) [SRC:/jsp/login.jsp:12] at com.orionserver[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].http.OrionHttpJspPage.service(OrionHttpJspPage.java:56) at oracle.jsp.runtimev2.JspPageTable.service(JspPageTable.java:350) at oracle.jsp.runtimev2.JspServlet.internalService(JspServlet.java:509) at oracle.jsp.runtimev2.JspServlet.service(JspServlet.java:413) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java:65) at oracle.security.jazn.oc4j.JAZNFilter.doFilter(Unknown Source) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:663) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:330) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:830) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpRequestHandler.run(HttpRequestHandler.java:285) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.HttpRequestHandler.run(HttpRequestHandler.java:126) at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:186) at java.lang.Thread.run(Thread.java:568)

The log file always shows below err, no matter what change I make:
