java.lang.ClassNotFoundException

Download and Installed tdk-1.1a13.tar.gz

Started turbine and it checked my username/password on my
Informix database. Everything was working fine.

Transfer my newapp which is "ny" to "tomcat-3.2.1/webapp" directory
modified "ny/WEB-INF/conf/TurbineResources.properties" and
"ny/WEB-INF/web.xml"

copy all *.jar from "ny/WEB-INF/lib" to "tomcat-3.2.1/lib"

started tomcat and in the servlet.log:
2001-04-14 12:43:43 - path="/ny" :ny: Turbine: init() Ready to Rumble!
2001-04-14 12:43:53 - path="/ny" :ny: Turbine: doGet() Start Initializing
Services!
2001-04-14 12:43:54 - path="/ny" :ny: Turbine: doGet() Finish Initializing
Services!

But when trying to insert data to RDF table got the following in
"ny/logs/turbine.log"

[Sat Apr 14 12:53:47 EDT 2001] -- ERROR --

That is odd, because there is a
"tomcat-3.2.1/webapp/ny/WEB-INF/classes/com/realinfo/ny/modules/"
and under it there are my actions and screens directory containing the java
classes and
yes the SQL.class is in the actions directory.

This is what I have for module packages in my "TurbineResources.properties":

module.packages=com.realinfo.ny.modules,org.apache.turbine.flux.modules

Can anybody answer why Turbine is not able to find SQL.class in tomcat-3.2.1
but is able to find it in
tdk-1.1a13.tar.gz?


Thanks!
Henry

It works when I jar all "flux" and "ny" classes and put them in
"tomcat-3.2.1/lib" directory.
So It can't be my configuration. I think it have to do with the ClassLoader.

You should just be able to copy the webapp from one container to the
other then. You have probably changed or editted something, copied
jars to the wrong location or something. The webapp should be
transportable, just moving it from one webapps directory in one
container to another shouldn't break anything. Everything is self
contained. But this is why we've spent so many hours making sure
trying to make sure things work in the TDK, I don't know what
your setup is, but it's probably a simple configuration error.

If a module is not being found which is the case with your SQL action,
and the Login screen above then your modules are in the wrong place,
or TR.properties is wrong, or the classes aren't there.

yes, I generate the sample app in turbine first then moved myapp (ny) to
tomcat.
I edited newapp.props to:

turbine.app.name=ny
turbine.app.view=velocity
turbine.app.type=peer

target.package=com.realinfo.ny
target.directory=com/realinfo/ny

This is the package listed in SQL.java:
package com.realinfo.ny.modules.actions;

>So you had this app working inside the TDK? You tested everything

Yes, It works in TDK, and I tested everything from insert,edit,delete on
RDF.

another strange thing is that what I tested it in TDK, it comes up with the
Login.vm screen while
in tomcat-3.2.1 it comes up with the Index.vm screen.

Thanks!

Did you generate the sample app first and then move it over?
What is the package listed in the SQL.java action? By default
when the app is generated it defaults to com.mycompany.newapp
unless you edit the newapp.props.

So you had this app working inside the TDK? You tested everything
before you moved it over to your setup?
