Hi Luis,
this is a beautiful morning. I don't know how but i solve everything.
This morning the first thing i did was another experiment to better
understand what was happening. So i rebuild Amazon stub classes with the
axis tool:
java org.apache.axis.wsdl.WSDL2Java -v -W -p myamazonservice
http://webservices.amazon.com/AWSECommerceService/2006-06-07/AWSECommerceService.wsdl
Then i put a System.out.println("TEST") inside the code of
AWSECommerceServiceLocator.java constructor to see if Axis reach that
point. I never saw that string printed out, but after the deploy of
everything, and after including those stub classes in the same jar of my
web service putted in TOMCAT/webapps/AXIS/WEB-INF/lib directory,
everything works fine!
I really don't know how but i escape from this labyrinth!
I hope you find your way out from yours.
Thanks to all,
Roberto.
Ps: If anyone understand what's happened to me (why now everything
works, he can tell me whenever he wants)

Roberto,
I found my problem. It turned out not to be a Classloader problem,
but a NullPointer problem in the server, which I had not found
because I don't know how to debug my application in Tomcat and there
is no single log in the Tomcat directory that can give me a clue of
what's happening.
Anyway, the configuration worked as I had it initially:
1) Stubs/Skeletons and all that had nothing to do with the JNI in
axis/WEB-INF/classes
2) The classes for the JNI interface/loading the jni library under
shared/classes
I think if we can find a way to debug our application in the server,
we could get better light on what is happening and solve problems a
lot quicker :|.
Anybody knows how to debug remotely axis/tomcat apps?

Roberto,
I have not solved the problem, but managed to understand that the
problem does is not where I drop the classes that will make the JNi
calls. Dropping them inthe share directory results in the
java.lang.reflect.InvocationTargetException at the Client side.
1) To be clear, the call to th e JNi wrapper (dropped in the
share/classes directoy) is something like this:
public void getCompany(CompanyHolder company, StringHolder result)
{...}
Making this call from the Stub implementation (dropped in
axis/WEB-INF/classes directory) result in the mentioned exception.
The clases ComapnyHolder is visible to both classes, and tthey are
in axis/WEB-INF/classes and axis/WEB-INF/classes.
2) For the sake of testing, I created a new method without parameters
public Stirng getCompany();
and made the call just like in 1, and IT WORKED ... not Exception at
the client side.
3) So, the problem seems to me is not wher eI drop the
implementation classes, but the classes with all the types and
hodlers generated with wsdl2Java, and it doesn't seem to be the
shared/classes directory, because that classloader finds it correctly.
It seems that there is another classloader in the middle, between
the one for shared and the one for my WebApp that needs to know
where to get these classes from, but where? ... I tried common and
server.... no luck !!!
HELP PLEASE !!!
Thanks in advance,

Those are all the experiments i did to solve this damned problem:
* Put the Amazon stub classes in a jar in the classpath of windows:
The source code of the web service will compile, and you will be
able to correctly deploy it. But when you will try to acces it
from a client, the first try to call AWSserviceLocator( ) will
cause the exception.
* Put the Amazon stub classes in a jar in the
TOMCAT/webapps/AXIS/WEB-INF/lib directory: Axis will not start.
You will get a 404 error, and i don't know why.
* Put the Amazon stub classes in the
TOMCAT/webapps/AXIS/WEB-INF/classes directory: Nothing change from
the first point.
* Put the Amazon stub classes in the TOMCAT/shared/lib directory: :
Nothing change from the first point.
* Put the Amazon stub classes in the same jar of the web service i
try to deploy and use: I put this jar containing Amazon stub
package, my ws sources, my ws stub classes in
TOMCAT/webapps/AXIS/WEB-INF/lib directory. I can deploy it but
nothing change from the first point.
I really finish my ideas to solve this problem. Is it possible that
no one had never try to use Amazon in Axis? I wrote on Amazon
forum, Nabble Axis forum, Java forum but with no succes.
I hope we find the solution :-(
Roberto.

Roberto,
I don't know the answer, but I am having the same problem. Same
exception but with a slightly different setup. I have a class
which will use a JNI library, which according to the documentation
should be place in the shared/classes directory. So I did and I
get the dreaded java.lang.reflect.InvocationTargetException, which
I believe is a class loader problem. However, I have tried to
solve this placing it in the common/classes, server/classes and I
get the same result.
I have searched the web for solutions, some people say that it is
a classpath problem, but nobody seems to let you know where
exactly you set this so that the correct class loader finds the
class (assuming I am right and it is a classloader problem).
Any of these AXIS gurus have had a similar setup/problem and have
a solution at hand?
Thanks in advance,

But if i put those stub files in a jar under the WEB-INF/lib Axis
cannot start.
My question begin: Can i invoke a web service on axis that will
invoke with some stubs the service of amazon? If yes, why i'm
still getting this exception?

Buon Giorno Roberto-
place jars in %TOMCAT_HOME%/webapps/axis/WEB-INF/lib
OR
place class files in %TOMCAT_HOME%/webapps/axis/WEB-INF/classes
Molte Grazie,

Subject: Where to put Amazon Stub classes
Hi all,
i have big problem. I'm trying to develop a web service that
will do simply
a search using amazon ws, and i want acces my service from a
java client. So
i put my web service jar in AXIS-HOME/WEB-INF/lib directory.
But here come
the problems:
Where i have to put Amazon stub classes obtained from the
amazon wsdl file?
In order to compile my java files for my web service, i create
a jar with
those stub files and putted it in the windows classpath. But it
seems to me
that Axis cannot see them because every time i try to acces the
web service
i got a java.lang.reflect.InvocationTargetException from Axis
but i can use
ut if i simply remove the amazon code. If i put that jar with
the amazon
stub in the AXIS-HOME/WEB-INF/lib directory Axis cannot start.I
get an error
404.
Thanks in advance,
Roberto --
