Subject Solved! Re: Geronimo WTP client for eclipse doesn't work as expected
Date Wed, 27 Feb 2008 12:55:39 GMT


Finally I found the source to the problem. When a project is created within
eclipse, an eclipse that has the Geronimo WTP client installed the Targeted
Runtime is set to Apache Geronimo as a default.

For my project that was created outside eclipse this isn't the case.

After comparing every little detail between these projects I found that
setting Apache Geronimo v2.0 as a targeted Runtime changes was noticed by
Geronimo. Looking back this seems quite obvious, it wasn't for me believe
you me.

over and out! // mett
