Congrats. I got the same about a month ago.
Makes you an IBM Certified Enterprise Developer - WebSphere Studio, V5.0 as well as a jCert Enterprise Developer.
I also just completed the IBM
Test 812 exam which makes me an IBM Certified for e-business - Solution Technologist.
Now I might do some Microsoft certs to broaden my eBusiness certs... though I'd like to do the Sun ONE App Server 6.0 exam (310-540) but I can't find any good study guides for it yet. Other than the training which is like $6K here in Australia.
