oAW has moved to Eclipse.

Hello

My name is nabil, I'm an enginner in 'SOFTEAM Objecteering software' in paris, and I work in about openarchitectureware 4.2 for code generation in Java

I try use Extensions whith Java, the class is :

package help;

[b]import data.*;

public class EntityHelper{
        public static String className(Entity e) {
        return e.getName()+"Implementation";
        }
        public static String classFileName (Entity e) {
        return className(e)+ ".java";
        }[/b]}

and file of extension is :

import data;
[b]import metamodel;

String className(Entity e): 
JAVA help.EntityHelper.className(data.Entity);
        
String classFileName(Entity e): 
JAVA help.EntityHelper.classFileName(data.Entity)[/b];

But, when I execute the woorkflow,I have always a problem which I can't resolve,The problem is 'argument type mutch'.

I don't see what I do wrong

Thanks.

Hi Nabil!

I assume the class Entity is really in package "data". Then the definition of your JAVA extension is right in principle. The argument must state the full qualified type names (here data.Entity). This would not explain the argument type mismatch problem.

But I wouldn't code this type of helper functions in Java anyway, since they are more easily defined in Xtend:

import data;
import metamodel;

String className(Entity e): e.name+"Implementation";
        
String classFileName(Entity e): e.className()+".java";

If you want to solve the type argument problem anyway you could try to debug this. You could define an exception breakpoint for the exception you get. You have to switch the launch configuration to debug in Java. Therefore open the Debug dialog and check the "Java debug" option.

Perhaps you could provide us some stack trace are other helpful information.

Hope this helps,
