Hi.,
 I debugged inside Seam code and found that in DocumentStorePhaseListener documentData is NULL


  |   DocumentData documentData = DocumentStore.instance).getDocumentData(contentId);
  |   byte[] data = documentData.getData();
  | 


Here's my web.xml file

In previous project we used JasperReports and now we want to use all features of SEAM. I don't want to go back to jasperreports. I think its just a silly config problem. 

Please help me.

Thanks
