Hi, I'm new in the list and I begin using apache-tomcat-5.5.23 with juddi.
My question:
When I change a parameter JNDI (jdbc/juddiDB) in the juddy project with
the Administration Tool I see the following log and my session is
invalidate.

Hi
We have implemented a picture server in Tomcat.
The pictures are cached in a map. When the memory is nearly full, some
entries are removed from map.
However, eventually the entries in the map become fewer and fewer even

Well... be careful on the use of the shared/common classloader. It
works as long as all the apps can use the same version of a library. If
there are changes to the API and you have the library in the shared or

You can actually use JAVA_OPTS or CATALINA_OPTS to add the options and

I also agree with David and, uh, David, that #6 is a little dubious.
Yes, moving shared libraries into the common/lib directory will save you
some memory, but it creates a management headache when it comes to
version numbers, WAR
I agree, i'm not willing to pay the management overhead of putting my shared
libraries to the tomcat common lib, unless my gains are very big in terms of
memory consumption.
I don't really think you should change for another one though, but you can
make regards about the cons of that approach.
#6 - Shared classloaders are evil, but not as evil as the invoker
