1. EVAL_PAGE
2. They both do nothing and return EVAL_PAGE
3. doStartTag is called before setBodyContent so I wouldn't realy on it
4. everything seems to throw JspException - I'm not convinced the difference
bewtween JspError and JSpException has been finalised yet (anybody from Sun
care to comment)
5. pageContext is a protected variable in 'TagSupport' - why do you need
getPageContext - it's available anyway? - It's also an intrinsic, available
to the JSP page as a variable called pageContext
6. never seen this one,
Kevin Jones

Subject: Six questions on Tag Extensions (PR2)
1. What is the return value of the methods doStartTag(), doEndTag()
respectively doAfterBody() in the support classes TagSupport and
BodyTagSupport?
2. How do the implementations of doEndTag() differ in the classes
TagSupport and BodyTagSupport?
3. Is it possible to use the method getPreviousOut() of class
BodyTagSupport in the implementation of the methods doStartTag() or
doEndTag() in subclasses of BodyTagSupport? Or can these methods
only use pageContext.getOut()?
4. Why does the method doInitBody() in class BodyTagSupport not
include the clause throws JspError?
5. What happend to the method public PageContext getPageContext() in
class Tag? Why was it deleted?
6. What happened to the method public java.lang.String getTagName() in
class Tag? Why was it deleted?
