The tomcat test environment of IBM for VAJ is still
version 3.1.
I heard that after the release of patch3 (which
also brings the internal Websphere TE to JSP1.1/Servlet2.2)
the will release another one with i presume the
latest final (3.2.1)
Struts works perfectly well in VAJ. I work with it
every day and it is very easy.
You have 4 projects and a updated Java Lib
Classes one (or another seperate project for javax.sql.Datasource)
1> Tomcat Test Environment
2> Struts project (imported source of binary's,
i preffer source)
3> You're project (with the \Web
inf)
4> JAXP the XML parser ect.
5 or The updated Java Lib Classes in which i have
the javax.sql and all the transaction pacakages.
Then alter the Tomcat Runner class in the Tomcat
Test Environment classpath so that i uses all
those projects.
I have the struts.jar also in the \WEB-INF\lib dir
but i don't think VAJ or Tomcat uses that because
i bug through the struts in internal the
project.
I do think struts get's loaded with the system
classloader. But why is that a bad thing in a development
environment?

& Struts
Tom,
We have Struts (Jan 16 build) and VAJ
3.5.2 working with the Tomcat Test Environment from IBM. It took a little
while to figure out, but we seem to have a repeatable process now. We started
with the "Mini-HOWTO" contributed by Nikolaus Rumm (http://kephera.dhs.org/services/vaj_jonas_struts_howto.htm)
and tweaked it a bit, since we weren't using Jonas. I'll attach our notes that
we kept on it if they provides any new insights for you.
Note that we're not using vanilla
Tomcat 3.2.1, but rather whatever version IBM packaged in their "Tomcat Test
Environment" (which appears to be 3.2.x?). The installation of the TTE is much
simpler than the process described by Sheldon Wosnick in his VAJ & Tomcat
articles.
Let me know if you still have any
problems, or if the Word doc doesn't come through, and maybe I can
help.

Struts Amigos
I am still trying to work out a way to develop
Struts applications
within Visual Age for
Java. (Feb. 19 Struts build, Tomcat 3.2.1, VAJ
3.5.2, see 'Problem w/ Struts and VA for Java' last Tuesday). I got
some
suggestions but have been unable to
reproduce the results.
I believe the problem has to do with the custom
class loader mechanism
of Tomcat which is
used for individual web apps. Craig explained in
"Classpaths and the "struts.jar" file (Feb. 13th (#4566)) why it is
that
struts.jar must be in WEB-INF/lib
and NOT on the classpath at execution
time. Classes visible on the CLASSPATH are loaded on by the
system
loader, and cannot find class for
classes which are loaded earlier by
the
custom class loaders of the web apps.
In trying to use VAJ, one would want all code (at
least all Struts code
(contents of
struts.jar plus your application code)) in the IDE instead
of in WEB-INF/lib. But that seems to put it effectively on
the
CLASSPATH, and thus loaded by the
system loader (the IDE environment).
It is not that hard to get Tomcat running from
within VAJ, but when one
trys to access a
Struts web app, say the struts-example, the first
bean:message tag throws a JSP exception, presumeably
because it is
looking for
WEB-INF/lib/struts.jar, instead of the Struts code within
the IDE.
I'm not sure, but I have a feeling that the
custom class loaders for web
apps may
pose a significant challenge to developing with Struts inside
VAJ. I know my understanding and/or my VAJ setup
are hosed somehow or
other, and that is
why I'm asking for help.
