Hi Pryia,

I'm having a very similar problem. I just posted the following topic: http://seamframework.org/Community/SeamExcelJBoss51Problem

If you find a solution for your problem, please let me know.

Hi,

Did you get any solution on this? I am stuck with the same problem. I am referring to the stylesheet in my workbook as:

<e:link URL="#{request.contextPath}/stylesheet/myexcel.css"/>

This works perfectly on JBoss 4.3 but I am getting the following exception on JBoss 5.1 (Seam 2.2.2 EAP):

Caused by: java.lang.NullPointerException
