[opencms-dev] Problem with Maintenance class

Hi,

Stephan Hartmann spoke about a such a problem at his installation too. But
on our system it seems to work fine. But we did a trick. This can be the
solution. We built a general maintenance class. This class is used for all
the times our new modules become installed on a server. There we load a
propsfile where all needed informations are in.
So this class is known already from the Tomcat.

When you install your class via the module-upload Tomcat didn`t know this
class. After a reload tomcat found the class via his own classloader. So
it can work. This issue isn`t a problem with our solution i think!
Hope this helps
