Adding a JSP page to an application

Question

Hi,
I want to add a JSP page called image.jsp to an oc4j service called analytics. I probably have to change something in the web.xml, but keep running into: 500 Internal Server Error
Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response.
my web.xml now looks like this:
<?xml version="1.0"; encoding="UTF-8"?>
<!DOCTYPE web-app
     PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN";
     "http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
     <servlet>
          <servlet-name>SAWBridge</servlet-name>
          <servlet-class>com.siebel.analytics.web.SAWBridge<;/servlet-class>
          <init-param>
               <param-name>oracle.bi.presentation.sawserver.Host<;/param-name>
               <param-value>localhost</param-value>
          </init-param>
          <init-param>
               <param-name>oracle.bi.presentation.sawserver.Port<;/param-name>
               <param-value>9710</param-value>
          </init-param>
     </servlet>
     <servlet-mapping>
          <servlet-name>SAWBridge</servlet-name>
          <url-pattern>/saw.dll<;/url-pattern>
     </servlet-mapping>
     <servlet>
          <servlet-name>image</servlet-name>
          <servlet-class>/image</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>image</servlet-name>
          <url-pattern>/image</url-pattern>
     </servlet-mapping>
     <mime-mapping>
          <extension>xsd</extension>
          <mime-type>text/xml</mime-type>
     </mime-mapping>
     <welcome-file-list>
          <welcome-file>default.jsp<;/welcome-file>
          <welcome-file>image.jsp<;/welcome-file>
     </welcome-file-list>
</web-app>
any pointers are much appreciated.
I'm a total newbie with configuring OC4J...

maybe something else?

hi John
There does seem to be a problem on line 44 of your image.jsp page:
java.lang.NullPointerException
at _image._jspService(_image.java:90)
SRC:/image.jsp:44
...Would you mind posting a part of your image.jsp page that includes line 44 (or the complete page if it is not too big)?
You wrote "... I probably have to change something in the web.xml, ...", why do you think that is the case?
