Dear All,
I am having a very bizarre problem to do with Tag Libraries. I am
currently designing a set of libraries to perform
Simple database connections and operations. As a result, I need a
"ifNotNull" tag, which takes a column attribute and only allows the
nested contents to be parsed if the current row is not null.
However, the tag I built for this does not work properly, so I reduced
the functionality to a basic tag, and it still does not work. The code
is as follows:
public class RandomTag extends BodyTagSupport
{
public int doStartTag() throws JspTagException
{
return EVAL_BODY_TAG;
}
public int doAfterBody()
{
return (SKIP_BODY);
}
}
This should simply allow any contents within the body to be parsed.
The TLD for this particular tag is:
<tag>
<name>ifNotNull</name>
<tagclass>dbTagLib.RandomTag</tagclass>
</tag>
The usage within the JSP is:
<dbConn:ifNotNull>
<dbConn:header fieldIndex="3"/> = <dbConn:field fieldIndex="title"/><br>
</dbConn:ifNotNull>
However, this header and field elements will not output, they work
normally, but not when nested within this ifNotNull element.
Can anyone shed any light on why this may not be working?
Best regards,
Peter Dolukhanov
