How to reuse the jakarta regexp

Hi,

is it possible to reuse the jakarta regexp?

The library comes with EP60 and can be found at

"cluster\server\additional-lib\com\sapportals\dqp\lib\jakarta-regexp-1.2.jar"

I can include the library in Eclipse and compile everything fine, but get runtime errors in the portal. Being an EP development newbie I tried to declare the library in the SharingReference property of the portalapp.xml, but this did not work either.

Thanks in advance

Wilfried
