Hi, all: Thanks for your help. Because BEA just changed the content of certification so I could not find the mock test link anymore. In fact I could not find the objective of the test also. It seems BEA changed a lot of for certification. I passed the weblogic 7.0 web server developer test last Saturday and got 72%. The real test is much harder than the mock test. The preparation material BEA gave us is not enough.
