The IBM #155 is in fact the SCJP2 ver 1.2 (310-025) test. I took the IBM 155 and received a certification from Sun for taking the Sun 310-025 exam as well as the pin from SUN. If you are going to take the JCert exams on a IBM track then
you should use the IBM 155. If you took the test with the SUN 310-025 exam you need to call IBM and make sure they know you took it. It apparently does not make a flash on there screen. Both tests (being the same) are accepted for JCert SCJP2 requirements.
If you take the test now you may consider taking the Sun 310-035 exam. This exam is the Version 1.4 exam. Then call IBM and make sure they know about it.. I would imagine IBM will be adding another number besides 155 to account for the new exam.
