Hi

Its depends on the design. but one another option for this is that you create a business delegate and call the multiple EJB's in it and in your managed bean you only call this dusiness delegate.
by using Business Delegate Design Pattern it will be simple to manage the EJB. If there is any change in the EJB or if you want to add another EJB you need to change only one file, you not need to change all the managed beans.

Hi

You can create class diagrams as big as it is required. But remember the digram should be clear and easily readable. If your diagram is easily readable it dosent matter how big it is. Also donot leave any thing in the class diagram like method parameter, value objects etc they should be in the class diagram.

Also provide some notes\comments for each and every class\ejb\dao\helper classes etc in the class diagram. by providing this, it is easier for the examiner understand the diagram.


Thanks

Hi

I have not downloaded any plug in for StarUML. No need to worry Just use StarUML 5.0.2 and create your diagrams.

Thanks
Hi

You can create your UML in UML 1.0 no need to change it in 2.0. I have also used starULM 5.0.2 version.

Just remember do not mix both (UML 1.0 and UML 2.0). just use either UML 1.0 or UML 2.0


Thanks
