I am testing Spring + DWR.
This should be very easy but the integration never works.
I have been getting stuck here for a week.
Can someone tell me what's wrong?

My Action is to access the following URL link:

Dear Theodore Casser

Thank you for the information.
The website does have a forum and some free mock exams.
I will try to join it.

Once again, thanks.

Dear Java Ranchers

Currently, the company I am working for decides to make a development team for Microsoft solution.
Can anyone tell me which website forumlike JavaRanch would like to help people pass Microsoft Certificates?

I appreciate for any information.

http://javaboutique.internet.com/tutorials/Swing/ (Part 1 & II)

After reading "Struts meets Swing", I think this article is great.
It provides a solution about how to integrate heterogeneous clients with the same backend server application.
I learned something new.

Thank you, Leo.

Please read UML 2.0 for fragments, frames, interaction operators.

http://www.sparxsystems.com/EAUserGuide/index.html?interactionoperators.htm

admin use case should be out of scope.

Congratualations !!!

Congratualations !!!

In StarUML, manually change framekind attribute to ref.

I used RSA to draw UML diagrams for SCEA.

Congrats........

no, api is not necessary.
Using ref fragment in sequence diagram is enough.

Thank you, all java ranchers here.

Steve,

Congrats.... Good luck for the future endevours...

Also, i really don't think score matters a lot. As long as you learn from the mistakes and understand what you have done wrong, its great.

By the way, wats next ?

Dear Muhammad.

I have not decided yet..
Maybe SCMAD....not sure

Congratulations!

How long did you wait for the result?

about 8 weeks.

Congratulations Steve !

BTW, you mentioned that you have used Ant ? Did you implement your design ?

Wei-ju

No.
I ran jar command to pack html pages and jpg files in Ant build of RSA.
