# Assume that everything is declared properly and the TLD specifies <body-content>scriptless</body-content>. What is the output of the JSP? (1 correct answer)





1. (Before)(After)
2. (Before)
3. (Before)My Body(After)
4. (Before)My Body

Answer: 3

But I think it should be 2

Can some one help?

Thanks

Kay

SKIP_PAGE is an invalid return value for doStartTag(). SKIP_PAGE will cause the rest of the page to be skipped when returned from doEndTag(), since you don't override this one, the TagSupports default implementation comes in which returns EVAL_PAGE

ok but if we return SKIP_PAGE from doStartTag() then does't it show any compiler error?

SKIP_PAGE is an int. It won't cause a compile error.

even if it is int, then how it decides its next step in the lifecycle? whether to skip body or to eval body?
