Hi All,

Pls clarify my below doubts in Custom Tags.

1.The JspFragment of the tag body is invoked by the container before the
doTag() method is called. This value, a BodyContent object is passed to the tag handler using the setJspBody() method.

---> Based on the tag life cycle, it seems to me that the above is true,
but it is not.(KB's Page:564) Pls help me to understand the concept.

2. In KB's Page 491,it is mentioned that tag-file is better than <jsp:include>. But later pages says that we can not use any JSP directives such as page, include and taglib in tag-file. Then how could we say that the tag-file is better than <jsp:include>?...

Thanks in advance.

Regards,
Yasin

You can use the regular JSP directives in a tag-file except the tag directive replaces the page directive. You do not have to declare the attributes in a TLD if you use the attribute directive (not on the SCWCD exam). There is also a variable directive for synchronizing page scoped variables (also not on SCWCD).

I hope that clarifies the latter part of your question.

Kevin
