Re: Tomcat 5: the classloader mystery

[Lars Ohlén <la...@ohlen.se>]

Hello again,

As I stated in the caption of this discussion. It is a mystery. But lets
face the facts:
If I had my classes to the CLASSPATH variable my application works. Else it
does not.

My WEB-INF/lib directory is empty and the common/lib directory only contains
what came with the installation.
The jre/ext/lib directory is also untouched. Tomcat installation is
out-of-the-box

And as still think it is a bad idea to have duplicates of the appserver
copied into the Tomcat directory structure. And
each EJB deploy to appserver would require an extra synch step (to make
remote interface and associated dao's available)


Perhaps I'm breaking some internal behaviour within Tomcat to alter the
CLASSPATH variable within the setclasspath.sh

Hi,

>Two things here: Classes in the CLASSPATH are visible to my web
application

They're not.  You may have placed other copies of the jars on the
CLASSPATH in your WEB-INF/lib or common/lib folders, or in the
jre/ext/lib type folders, or you may have custom built tomcat to do
this, but otherwise the above is wrong.

Several MB is nothing, disk space is cheap, unless you're working in
some sort of mobile / flash / j2me device.  You're not duplicating the
whole application server, only the EJB client jar which is typically
even smaller than several MB.
