Subject FOP class loader problems in WebSphere
Date Mon, 23 Apr 2007 23:15:35 GMT
Hello,
I am running my web application on WebSphere and I am passing a XSL-FO 
file to FOP to create a PDF.  For some reasons, I got the following 
exceptions about the WebSphere class loader.  Any help would be very 
appreciated.....
Thank you very much,
Hai-Fun Wu
