Papyrus UML to Java using Acceleo [message #1016638]

I want to convert the papyrus UML model to java using Acceleo.
I followed the steps at http://wiki.eclipse.org/Acceleo/Getting_Started
, but get this error when i run generate.mtl "An internal error occurred during: "Launching Generate".
Could not find public template generateElement in module generate."

Here is the template file I use. What could be the issue?
[comment encoding = UTF-8 /]
[module generate('http://www.eclipse.org/uml2/4.0.0/UML')/]

[template public generate(aClass : Class)]
[file (aClass.name.concat('.java'), false)]
public class [aClass.name.toUpperFirst()/] {
[for (p: Property | aClass.attribute) separator('\n')]
private [p.type.name/] [p.name/];
[/for]

[for (p: Property | aClass.attribute) separator('\n')]
public [p.type.name/] get[p.name.toUpperFirst()/]() {
return this.[p.name/];
}
[/for]

[for (o: Operation | aClass.ownedOperation) separator('\n')]
public [o.type.name/] [o.name/]() {
// TODO should be implemented
}
[/for]
}
[/file]
[/template]

Hi Roshni,

It seems you forgot to add the @main annotation.

[comment encoding = UTF-8 /]
[module generate('http://www.eclipse.org/uml2/4.0.0/UML')/]

[template public generate(aClass : Class)]

[comment @main /]
[file (aClass.name.concat('.java'), false)]
...

Hi

It looks like a design decision. The main template is different. It could have a special name such as Java's "main". it could have a reserved position - first. It could have a non-standard syntax. The designers chose an @main comment. (It might help if there was a warning for no-@main-comment.)
