Sorry i mix to many functions :) I read a second time the javadoc and i
discover you can't use both handlePut() == lowerlevel
and put() == high level.
So i have another issue if something can give me a clue:
When i try to get my data form from the handlePut() or the handlePost() with
this code it works very well !:
@Override
public void handlePut() {
System.out.println(" handlePut()");
Form form = getRequest().getEntityAsForm();
String formId = form.getFirstValue("formId");
System.out.println("=> formId = " + formId);
super.handlePut();
}
@Override
public void handlePost() {
System.out.println(" handlePost()");
Form form = getRequest().getEntityAsForm();
String formId = form.getFirstValue("formId");
System.out.println("=> formId = " + formId);
super.handlePut();
}
But now when i try to use the default implementation with put() and post()
method with this code it fails ! :
I get this from this post
http://article.gmane.org/gmane.comp.java.restlet/2420/match=form+post (i
check the sample this is how it should work)
@Override
public void post(Representation entity) {
System.out.println(" post()");
if (entity != null) {
Form form = new Form(entity); //throws error
String id = form.getFirstValue("formId");
System.out.println("=> formId = " + id);
}
}
@Override
public void put(Representation entity) {
System.out.println(" put()");
if (entity != null) {
Form form = new Form(entity); //throws error
String id = form.getFirstValue("formId");
System.out.println("=> formId = " + id);
}
}

SEVERE: Unhandled exception or error intercepted

Somebody can explain in which case to use the handlePut() and the
put(Representation entity) ?
Thanks a lot for the reply
