RE: [smila-user] Integration of servlets
|
Hi
Giorgio,
I don't know the necessary settings, but please try the following:
Remore the import for javax.servlet and use Require-Bundle:
Require-Bundle: javax.servlet
Also I think you have to add an import for org.apache.catalina;version="6.0.18".
Kind regards
Sebastian
