seam pdf generation configuration problem.

[bhaskarpatle]

Hi,

I am trying to generate pdf file using Seam's iText document support. For that i have added jboss-seam-pdf.jar and itext-2.0.1.jar to WEB-INF/lib directory. but I got the following exception

18:33:13,218 ERROR [ExceptionFilter] handling uncaught exception
javax.servlet.ServletException: Servlet execution threw an exception
Caused by: java.lang.NoClassDefFoundError: org/jboss/seam/core/Pages

for that I add jboss-seam.jar which removes above exception
but now I am getting another exception

17:46:30,531 WARN  [lifecycle] executePhase(RENDER_RESPONSE 6,com.sun.faces.context.FacesContextImpl@d90e02) threw exception

I had components.xml and web.xml which contains configuration as given in itext example.

Any help would be appreciated!!

Thanks

The stack trace looks like your forgotPass seam object does not have a get/set for the field testMe.

For packaging advise (jars files and locations) view the seam examples.

hope this helps

[bhaskarpatle]

No it is not like that I had get/set methods for testMe.
This exception comes only when I add jboss-seam-pdf.jar.
If I remove this jar from WEB-INF/lib the application run properly without any exception.
I had configured jar files and their locations as per seam examples, but no luck.
my components.xml is

Do I miss anything???

Hi,

I'm not sure what deployment model you are using, but if it's an EAR with a WAR inside it, then rather than having the jar files in WEB-INF/lib of your WAR, they should be inside the EAR, and with <module> entries in your application.xml, example:

   <module>
      <java>jboss-seam-pdf.jar</java>
   </module>   

Your above exception may come from having two copies of Seam classes in action.

[bhaskarpatle]

Yes, it's an EAR with a WAR inside it.
So I did changes and moved jar files from WEB-INF/lib of WAR to EAR and added an entry in application.xml but still having the exception

11:43:34,265 ERROR [ExceptionFilter] exception root cause

and browser gives warning message The page isn't redirecting properly
I had jboss-seam.jar in my EAR with entry of it in application.xml and I think above exception generally came because of not having jboss-seam.jar.

Still struggling to find the solution :-(

Thanks
