Hi Larry,
my virtual host configuration seems fine to me.
I suppose it is a problem of configuring the class loader!?
I have a separate 'work' directory for each virtual
host. And of course I store all classes, .jsp and so on
in the WEB-INF directory of each virtual host's
application.
When I look into the 'work' directories I can see,
that in each one there are the following files:
ls -ltr /var/tomcat/www.tiade-voboe.de/wapps_2FjRolodex
total 29
drwxr-xr-x 4 root root 104 Jan 9 23:49 ..
-rw-r--r-- 1 root root 1 Jan 9 23:49 webxmlval.txt
-rw-r--r-- 1 root root 8768 Jan 9 23:49 numguess_1.java
-rw-r--r-- 1 root root 4827 Jan 9 23:49 numguess_1.class
-rw-r--r-- 1 root root 1 Jan 9 23:49 numguess.ver
drwxr-xr-x 2 root root 176 Jan 9 23:49 .
ls -ltr /var/tomcat/javadex.tiade-voboe.de/wapps_2FjRolodex
total 29
drwxr-xr-x 4 root root 104 Jan 9 23:49 ..
-rw-r--r-- 1 root root 1 Jan 9 23:49 webxmlval.txt
-rw-r--r-- 1 root root 8720 Jan 9 23:49 numguess_1.java
-rw-r--r-- 1 root root 1 Jan 9 23:49 numguess.ver
-rw-r--r-- 1 root root 4827 Jan 9 23:49 numguess_1.class
drwxr-xr-x 2 root root 176 Jan 9 23:49 .
Looks great, doesn't it.
But I get the error regardless!
Not so cheerfull ;)
