Hi All,

I am using RSM 6 and 7. I need to model a class diagram with operation
that throws an exception.

public String myMehtod(int a, String b)throws Exception{

Have a look at the old uml newsgroup 'eclipse.tools.uml2' around December
14 there was a thread about this.
The title of the message was "Modeling Exception Handling".

Regards,

- James.

Thank James,

I read those messages, but I feel it is not going to solve my problem

I am further specifying my problem below,
I want to model a class diagram with a method called "ReadMyFile" and that
method throws the FileNotFoundException exception (that is built in java
exception).

So, How can I model java FileNotFoundException exception, It is better if
you can give answer related to RSM modeling.

I am specifying some RSM related exception handling tips below,

1. There is a property for method parameters in RSM called "Is Exception".
2. Also, there is another property for a method called "raised exception"

Thanks.

From RSM if you visualize your java class, you will get a "disruptable"
combined fragment for exceptions but this is a RSM customization and not
part of the official spec. You might want to try visualization of your
class to get a customized sequence diagram.

Apart from what is described in the old newsgroup regarding modeling
exception handling, I'm not aware of any other better (standard) way of
modelling exceptions. Why are those tips from the old newsgroup not
sufficient for you?

I think that modelling exceptions is a sore point for UML in general.

Regards,

- James.

In this specific scenario, where a user wants to structurally model an
operation and the exceptions it throws, I actually can't see what is
lacking. The raisedExceptions property seems to be good enough. Or am I
missing something?

It seems that what the OP wants is easily doable with UML2. The issue
here steems from the fact that the OP actually wants help on how to do
that with RSM, and that kind of question certainly does not belong to
this forum, and should be asked elsewhere.

Hi Rafael,

What's an OP?
I agree that it is not fair to focus on product specific questions in this
forum.
