We need to see if its possible to make our big complex application work on
WebSphere 4. We had it working on 5.
The ui is done in struts and it was suggested that struts1.1 couldnt be used
with WepSphere 4 as WS4 uses the 2.2 servlet API. I figured this shouldnt be
a problem as struts supports 2.2 and doesnt need 2.3
Nevertheless I havent even been able to get a simple test application to run
on WAS4. (Something of a struts equivalent to hello world". - One action
that does a println to the response to prove you reached it)
This test app deploys and runs just fine in tomcat 3.3.1a (a servlet api 2.2
container) and of course in 4.0.6, but on websphere the ActionServlet dies
in the init method with:

Is this just something Im doing wrong (ideas on what would be appreciated!),
or is it really true that you cant use struts 1.1 with websphere 4?
<useless-information>
Its a simple app I banged together with one action that writes a string
directly to the response.
Its got a whole bunch of libs in WEB-INF/lib as Im not sure what struts
needs and doesnt:
ie:
commons-beanutils.jar
commons-collections.jar
commons-dbcp.jar
commons-digester.jar
commons-fileuplaod.jar
commons-lang.jar
commons-logging.jar
commons-pool.jar
commons-resources.jar
commons-validator.jar
jakarta-oro.jar
jdbc2_0-stdext.jar
log4j-1.2.7.jar
struts.jar
My logging properties are set up to use log4j, though Im not calling the log
in my action.
Various config files are in my WEB-INF
struts-config.xml
tiles-def.xml
validation.xml
web.xml
struts-config has been set up as simple as possible - just maps one path to
one action. The other files are untouched and would be same as whats in the
struts blank war.
