Check this link for more info on class loading. http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html
But it was my understanding that only Tomcat loads the classes and jars located in the /server directory. If you need access to it in your webapp, you have to either put the jar in yourwebapp/WEB-INF/lib or in the shared library section. For 4.0.4, shared libraries go in %CATALINA%\lib. With 4.1.x, they go in %CATALINA%\shared\lib. - Andrew > -----Original Message----- > From: Andreas Probst [mailto:[EMAIL PROTECTED]] > Sent: Monday, July 15, 2002 7:07 AM > To: [EMAIL PROTECTED] > Subject: RE: newbie - finding class files > > > Hi all, > > does Tomcat really look into tomcatdir/server/lib?
