when I try to call Servlet2 from index.html I got an error
Error 500--Internal Server Error

UseAMeaningfulSubjectLine, lots of people are here asking questions because they got an error. The fact that you got an error doesn't help determine whether someone might be able to or are interested in trying to help.

On to your error...

Sound like a java version issue. StringBuilder was added in Java 5. What versions of java and weblogic are you using?
