Debian Sarge und tomcat 4.0.4 mit j2sdk 1.3

[Andreas Rabus <andreas.rabus@entity38.de>]

Hi List,

i had a problem with my two Sarge machines.
On both maschines were j2sdk 1.33 from Blackdowan and tomcat4 installed

j2sdk1.3       1.3.1.02b-2    Blackdown Java(TM) 2 SDK, Standard Edition
tomcat4        4.0.4-4        Java Servlet 2.3 engine with JSP 1.2  
support

On Friday both maschines were unable to start tomcat4 again.
The error given in catalina.out was:

Exception during startup processing
java.lang.reflect.InvocationTargetException:  
java.lang.UnsupportedClassVersionEr

I solved this porblem with installing j2sdk1.4.5 (Blackdown, too)
an adding an "export LANG=de_DE" to the startupskript.

But some of the running Applications have problems with java 1.4, so  
update Applications (what and where will be time consuming) or  
downgrade tomcat (if an upgrade broke it, that is)?

What happend?
Did an (unnoticed) upgrade broke the compatibility with java 1.3?
Was ist a library ?

Can anybody help?

Thank in advance,

	Andreas
