If I add a template file (simple.get.html.ftl) as this:
And
This is the response:
For one moment, I was very Happy for this, but… if I change some data, if I make any operation, if I launch exception (e.g. webscript exception with 400 code), AND if I delete my JAR, the response is still the same!!!
I think the problem is in Alfresco. It doesn't recognize the class files and it manages the Java backend webscript as a simple webscript without java code. How … ?
ops:
Anyone have the same problem?

Thank you for your reply mrogers. 
Me too.
Off course, this is the problem.
I'm new on Alfresco Web Script development, but I've only one problem: deployment!
I followed the Alfresco Wiki and "Alfresco 3 Web Services" book where is described step by step webscript deployment. The problem is in the directory path I used (I think).
Where I can put the files? :shock:
This morning I've traied another example.
HelloworldJavaWebScript.java
jhello-context.xml
jhello.get.desc.xml
jhello.get.html.ftl
I think files are correct. It's wrong?
I've compiled JAVA into CLASS and this is my directory:
Now, the problem is the files' location. I founded many location, many classpath and more. But, none is the correct place.
WHERE? XD I don't understand this. Where I could put che class file? JAR file (WEB-INF/lib doesn't work)? Descriptor and template files? Which what folder tree?
Actually, this is my situation:
And this is the result:
Thank's a lot.
I find your description unclear but I do note that I don't see your Java Backed Web Script being registered anywhere.
Me too.
