Java Development Tools

Dear Experts,

I am using Jdev 11.1.1.5.0, I developed an application and the app can be successfully accessed through Integrated Weblogic Server.

Now I Installed, Standalone WLS, 10.3.5 in my system, I deployed the .EAR file in standalone,and the application is accessed fine, but I cant open a report(Jasper Report), which shows,

java.lang.NullPointerException

        at java.io.File.<init>(File.java:222)

        at test.stri.oracle.view.Serve.ReportServe.TEST.doPost(TEST.java:92)

        at javax.servlet.http.HttpServlet.service(HttpServlet.java:727)

        at javax.servlet.http.HttpServlet.service(HttpServlet.java:821)

        at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run

(StubSecurityHelper.java:227)

        at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecuri

tyHelper.java:125)

        at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.jav

a:300)

FYI, I can generate the same report in Integrated Server. Anyone pls guide me.
