RE: [tcljava-user] Tcl scripts inside EJB

[Vikram R. <Vi...@PL...>]

hi,

It was a classpath problem. The Jacl interpreter loads classes using the
JAVA_CLASSPATH, while weblogic uses the WEBLOGIC_CLASSPATH. For the
interpreter to be able to load classes within scripts, they need to be in
the java classpath. This again can be a problem at times with weblogic since
classes specified in both classpath variables cannot be loaded correctly by
weblogic. But I guess, we need to live with that :-)

regards,
Vikram Rajan
