Description

I have a big problem, look my example:

public abstract TemplateNode {}

public class FieldTemplate extends TemplateNode{};
public class FieldGroupTemplate extends TemplateNode{};

public class Template {
private List<TemplateNode> nodes;
..
}

Template t = new Template();
t.add(new FieldTemplate());
t.add(new FieldGroupTemplate());
// get service

service.insertTemplate( template );

****
I get error, 'cannot instantiate class null'.
In debug, i found this:
if(isInterface) {

} else if (isException) {

} else {
object = clazz.newInstance(); // but is abstract!!!
}
Xfire is trying to instantiate TemplateNode but he can't, because is abstract.
What i need to do?

Tkz.

Its not possible to instantiate abstract classes currently with Aegis. I think we could add it as a feature at some point in the future though.

Well you could add the feature yourself and submit a patch.

If you are trying to use object inheritance with Aegis, check out the section in the user's guide: http://xfire.codehaus.org/Aegis+Inheritance. This way if you send Foo which extends AbstractFoo, it will be correctly reconstructed on the other side.

I have this same issue using 1.2.5, has there been any workaround/patch created for this? I did follow the instructions on Aegis in the user's guide and still have same issue. I guess at this point one of our alternatives is to use JaxB, but we have spent a lot of time on configuring Aegis for the webservice and from our XFire client within Mule.

Thoughts on how we can proceed?
