Re: Cross context c:import not working?
For the archives : this is bug 27309 ( http://nagoya.apache.org/bugzilla/show_bug.cgi?id=27309 ) and has been fixed in head. -a Aadi Deshpande wrote: Hi, I'm not sure if this or the taglibs-user is the right place for posting this, but it looks to be a Tomcat error.
