Re: tomcat 6 - setting classpath
We ran into an exact same problem. Our workarround hack classpath.bat and classpath.sh works perfectly. I also considered running down the ClassLoader route. That also works but it felt more wrong. I was just going to ask what the accepted way of doing this was but I think I've got my answer.

tomcat 6 - setting classpath
Hi On tomcat 6.0.18 i need to set the classpath of a webapp, its the only webapp running inside this tomcat. i believe i need to do something like the following in the web.xml context-param param-nameclasspath/param-name param-value/my/webapp/conf/param-value /context-param but this seems ignored so can anyone point me to the syntax of what this is and where to put it ? thanks - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: tomcat 6 - setting classpath
Why not use WEB-INF/lib directory? quite a long story BUT that locations contains _default_ setting ie those for dev and when it goes into prod i need to override those with settings from the config directory - so i need to be able to manipulate it on the fly so to speak while still being able to use the same war. hope that helps explain a little - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Is the difference only between configuration files, or between jar files
also?
I suggest to keep such configuration file outside of webapp - e.g. in
${tomcat}/lib/classes. So you'll have dev tomcat setup, prod tomcat
setup and one war file.

it is only configuration files - no jar changes. I am trying to get
these stripped from the war but thats a difficult process, i know i can
do it in about 5 seconds but its a 'process' thing and then the war is
'different'
Is what i am asking not possible?

One can nest Loader component inside a Contex one. Your custom Loader component could use different class loading mechanism. I have never tried it, and I doubt it's worth your time. It's better to process your 'process' and change the way war file is built ;-) http://tomcat.apache.org/tomcat-6.0-doc/config/context.html http://tomcat.apache.org/tomcat-6.0-doc/config/loader.html -- Mikolaj Rydzewski m...@ceti.pl smime.p7s Description: S/MIME Cryptographic Signature
