Jasper basic issue (with websphere?)

[j alex <st...@gmail.com>]

Hi,

I just started using the S2 - Jasper plugin ; new to Jasper as well ; but
not able to get a simple report to show.

Below is my struts xml entry :

    <package name="cap-default"
extends="struts-default,jasperreports-default">

            <action name="newapp" class="com.mypage.TestAction">
                  <result name="success" type="jasper">
                   <param name="location">/jasper_compiled.jasper</param>
                   <param name="dataSource">ds</param>
                   <param name="format">PDF</param>
                 </result>
            </action>
    </package>

and in TestAction :

        JREmptyDataSource ds = new JREmptyDataSource();
        return SUCCESS;

The jasper_compiled.jasper is a compiled report (generated using a
standalone Java program) in WebContent.

The console trace is :

I'm not sure if this is a websphere specific issue since all the messages
are coming from the container.

Please advise.

Thanks,
