Subject Re: Unable to compile class for JSP
Date Thu, 30 Sep 2004 12:16:29 GMT

Probably because JWSDP 1.4 force me to use ant of them distrib which is 
and some others elements I use need 1.6.1 or more. So I have both 
releases install 1.6.1is in my classpath and jwsdp ant is set in the script.
This must generate a conflict.

I probably have to swictch to tomcat 5.028 which will enable me tu use 
ant1.6.1 for everything. (yes ?)
I use only jsp and servlets. Do I need to download something more than 
Tomcat distrib ?

Best regards
