[opencms-dev] Antwort: Re: Problems finding the lib-directory

Tue Jul 14 14:35:36 CEST 2009

This is more question about Tomcat class loading. Worth reading about the
order of class loading from Tomcat documentation, but the general rule is
that:

Commons/lib and shared/lib are shared between the webapps. Then if you put
something in webapp lib directory, this should overwrite the stuff in
commons and shared and further if you put classes in the webapp classes
directory this will overwrite all jars. 

However, sometimes you end up with conflicts between commons, shared and
webapp libs if you have different version of the same jar lying around.

Maybe check commons/lib, shared/lib and opencms/WEB-INF/lib for conflicts?

Regards,

Olli

Hello Jonathan,

thank you for your answer. I think since the directorys owner is "tomcat"
with rwx-access, this shouldn't be the problem.
More interesting ist your second question: Where can I determine, which
directory OpenCms has to look up for the libraries?

Thanks in advance

Best regards

Frank

Strange. Does the user running Tomcat have access to the .jar files in
/src/tomcat6/webapps/opencms/WEB-INF/lib? Are you sure that's the lib folder
your OpenCms instance is looking at?

Subject: [opencms-dev] Problems finding the lib-directory

Hello mailing-list,

I have a strange problem with OpenCms finding the jars in the lib-directory.
First of all, I have a windows-based development-server on which everything
runs fine: If I put a new jar-file into the directory
"C:\Program Files\Apache Software
Foundation\Tomcat-eclipse\webapps\opencms\WEB-INF\lib"
everything works fine (which means the classes in the imports of the jsp's
work).

On the openSuse Linux 11.1 production-server on the other hand OpenCms
doesn't seem to find the added jars in that directory
"/srv/tomcat6/webapps/opencms/WEB-INF/lib"
I get arrors like "Only a type can be imported. x.y.MyClass resolves to a
package ". These java-errors vanish when I manually copy the respective
class-files into the class directory of the module.
But I prefer to have the jars centrally in the opencms-lib directory, since
several modules use these libraries.

Does anybody have an idea, in which config-file I have to change something
to make this work?

Thank you in advance

Frank
