Jsp-file="/WEB-INF/index.jsp" cannot load

Question

          Hi,
          I am defining a servlet in the web.xml file using the following syntax.
          <servlet>
          <servlet-name>TestServlet</servlet-name>
          <jsp-file>/WEB-INF/index.jsp</jsp-file>
          </servlet>
          Then when I tried to access this servlet, I get a 404 not found error. The weblogic.log
          file complains with the following message:
          java.io.FileNotFoundException: no resource '/WEB-INF/index.jsp' in servlet context
          root '/home/dev/web/apps/MyApp'
          at weblogic.servlet.jsp.JspStub.compilePage(JspStub.java:293)
          at weblogic.servlet.jsp.JspStub.prepareServlet(JspStub.java:227)
          at weblogic.servlet.internal.ServletStubImpl.getServlet(ServletStubImpl.java:200)
          at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java:115)
          at weblogic.servlet.internal.ServletContextImpl.invokeServlet(ServletContextImpl.java:922)
          at weblogic.servlet.internal.ServletContextImpl.invokeServlet(ServletContextImpl.java:886)
          at weblogic.servlet.internal.ServletContextManager.invokeServlet(ServletContextManager.java:269)
          at weblogic.socket.MuxableSocketHTTP.invokeServlet(MuxableSocketHTTP.java:380)
          at weblogic.socket.MuxableSocketHTTP.execute(MuxableSocketHTTP.java:268)
          at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:129)
          My jsp file in located in /home/dev/web/apps/MyApp/WEB-INF/index.jsp, I know weblogic
          doesn't support jsp under WEB-INF, however, according to Sun's Servlet specification,
          anything under web-inf should be accessible to getResource and getResourceAsStream
          method, and it looks like that's what weblogic implementation is using (from the
          error message). So I am not sure whether this is weblogic issue or I am doing
          something wrong. By the way, the above config in web.xml is supported in Tomcat.
          

Answer 1

          What version of WebLogic will incorporate Servlet spec 2.4 and allow jsp under
          web-inf?
