tagdependent means that your TAGLIB will manage the body content.
text in its own manner. You can have tagdependent as
``empty'' to mean that there is no body content
<eg:contextPath/> == out.println( request.getContextPath() )
You should use subclass the `javax.servlet.jsp.tagext.TagSupport' class
Or suppose you written a custom tag to perform an SQL query
<eg:querySQL>
SELECT customer_name FROM preferred_customers
</eg:querySQL>
Then here it the tag `querySQL' must be tagdependent, because your
tag in dependent on the body content, that appears between the
start tag and end tag.
You should use subclass the `javax.servlet.jsp.tagext.BodyTagSupport' class
In particular you have create a `doAfterBody()' method that retrieves the
body content
doAfterBody() {
BodyContent bc = getBodyContext();
JspWriter out = getPreviousOut():
// You perfrom the JDBC query here but I make the string
// UPPERSCASE here!
out.write( bc.getString().toUpperCase() );
return SKIP_BODY;
}

Subject: Tag Library Descriptor problem - What does tagdependent mean?
Hi gurus!
I have a problem when writing a tag library. The problem is:
I want to get the content of a custom tag in the corresponding tag
handler, but I don't want that content is displayed in the browser. I have
written:
<tag>
<name>testiterationtag</name>
<tagclass>com.mycompany.TestIterationTag</tagclass>
<bodycontent>tagdependent</bodycontent>
</tag>
in my tag library descriptor. And this is the extract from my JSP page:
<%@ taglib uri="WEB-INF/testtag.tld" prefix="eg" %>
<eg:testiterationtag>aa</eg:testiterationtag>
I think "aa" will not be displayed. But it alway is displayed in the
browser.
So why is it displayed? When should we use the tagdependent value in tag
library descriptor? I can't find any examples using tagdependent value.
Thanks in advance.
Regards,
Thai
