using jacl and tcljava with tomcat - was Re: problem calling tcl
from jsp (maybe OT)
Hi all - just as info (and to get it in the archive and maybe a FAQ somewhere)
I found that to get jacl and tcljava jars to work with tomcat (3.3.1 anyway)
I had to do the following...
1. place the jacl and tcljava jars in $JAVA_HOME/jre/lib/ext
2. remove the jacl and tcljava jar's from the classpath (not sure this
is absolute requirement but it works)
3. remove the jacl and tcljava jar's from the tomcat container dirs
(i.e. apps, common etc.)
4. it is OK to leave the jacl and tcljava jar's in local WEB-INF/lib
after this, jacl is able to find the init.tcl file located in the
jacl.jar file and things work like a charm -- in jsp, in beans,
taglibs etc.
I was using tomcat 3.3.1 and Java HotSpot Client VM Blackdown-1.3.1_02a-FCS
with javc/tcljava 1.2.6 (also tried 1.3 though it's, apparently, not ready
for prime time)
