Adding on to the topic of this thread, i would like to know does the IBM certification for Websphere is covering 5.1 version as well.
It should be, as there is a small difference between the version 5.0 and 5.1. It should be some bug fix in 5.1. I think, in the exam, you may not see Qs that are so *IDE minor version dependent*. Of course, if you consider the versions 4,x and 5.x, it is another story. Nick.
