nested custom tags in JSP

[Saurabh Singhania]

Hi All,

Is it possible to pass attributes to a JSP custom tag using another custom
tag? I.e.:

<mytag:something parm1="value1" parm2="<mytagther/>"/>

Works as expected if I pass a string or a JSP expression, but embedded
custom tags are not evaluated. They are simply passed as plain text to my
code, which is of course not very useful.

Any help would be appreciated!

JSP obeys XML rules, which don't allow for a tag within another tag (by
which I mean a tag within the < > for an opening tag).

But, a tag can be contained by another tag (which would actually fit the
definition of nesting), such as:

<mytag:something parm1="value1">
<mytagther />
</mytag:something>

Or maybe:

<mytag:something parm1="value1">
<param>
<name>parm2</name>
<value><mytagther /></value>
</param>
</mytag:something>


Then your logic for mytagther can set values that the
mytag:something.doCloseTag can work with.
