Got Exception when run a report

Jliu

Hi there,

I got an exception like when I render a page which contains a birt report through JSP tag <birt:viewer reportDesign="myreport.rptdesign"/>. Exception is like this:

Caused by: org.eclipse.birt.report.engine.api.EngineException: Can not open the report archive.

The weird thing is if deploy my WAR file separately on JBoss, the page renders OK. But If I deploy my WAR under a enterprise.ear, it gives me this error.

In my application.xml, I have this:

<module>
<web>
<web-uri>birt.war</web-uri>
<context-root>/_enterprise/birt</context-root>
</web>
</module>
I wonder if I should adjust reportDesign="myreport.rptdesign" to reportDesign="/_enterprise/birt/myreport.rptdesign" ? I actually tried that, but still not working. I wonder why the error msg says "Can not open the report archive", is there an archive folder located somewhere?

thanks,
Jane

Jane,

My guess is this is a permission error. When the viewer is deployed there is a setting to write the report documents to a specific folder.

<!--
Temporary document files directory. Defaults to ${birt home}/documents
-->
<context-param>
<param-name>BIRT_VIEWER_DOCUMENT_FOLDER</param-name>
<param-value></param-value>
</context-param>

If you are using a frameset mapping in the viewer tag a rptdocument gets created in the above directory. My assumption is the document is not getting created. To test this add the pattern attribute to the viewer tag and set it to run instead of framest. This will not create the report document which is needed for pagination etc, but will test to see if it may be a permission issue.
