Re: [aspectj-users] Re: Aspect and Exception Handle

Hi,

If you have a situation like this:

class Foo {
   public void boo() {
       try {
           ...
       }
       catch(Exception e) {
           ...
       }
   }
}

and you would like to advise the handler, you could have an advice
that is something like the following:

before(Foo foo, Exception e): handler(Exception) && within(Foo)
       && args(e) && this(foo) {
   ...
}

You would then have access to the class via the foo object.  Is this
what you are looking for?  Or did you want to completely remove the
try/catch block via an aspect?

Hi ! This is the sample code that i sad in the early message.I hope for your
helps.

// Method in the Class

message = "Erro ao Iniciar Conexão";

title = "Servidor Indisponível ! :-(" ;

CaixaLogon.showMessageDialog(contentPane,message,title,CaixaLogon.NO_OPTION);

}

...../////////////////////// end class

}

// Aspect to replace the catch block.

public aspect HandlerTeste {



pointcut erro(): call(*
ClassName.jMenuFileCon_actionPerformed(..));



pointcut erro(): handler(MalformedURLException+);

before(ClassName cl): erro() && target(cl){

// to have access to variables in the class like message,title and
Caixa.Logon to replace the bloc catch to // aspect

System.out.println("Tratamento de runtimeexceptio !!");

System.out.println("Trate o erro aqui !!");

}



}


Thanks !
