Hi Experts:
I have read "class not found" in FAQ and "class loader howto" of
tomcat6, unfortunately, they don't resolve my problem.
I set CATALINA_BASE and CATALINA_HOME to my directory like:
CATALINA_BASE=/usr/share/mydir
CATALINA_HOME=/usr/share/mydir
then link subdirs (conf/, bin/ ...)of tomcat6 to $CATALINA_HOME,
the "lib/" points to /usr/share/tomcat6/lib. IMO,
tomcat6-servlet-2.5-api.jar, tomcat6-jsp-2.1-api-6.0.26.jar,
tomcat6-el-2.1-api-6.0.26.jar should be automatically be found since
they are located at $CATALINA_HOME/lib/. In fact this doesn't work, I
got errors (see paste at bottom). However, if I added full path of these
JARs to classpath, things worked. I am puzzled, why common class loader
doesn't get these files? thank you.
