In a custom task, I need to use a nested element to set the port number.
The nested element looks like this:

<c:myCustomTask>
<port>9090</port>
<context>myApplication</context>
</c:myCustomTask>

The problem I am getting is:

build.xml:76: class java.lang.String doesn't support nested text data
("myApplication").

And the same thing for the port.What type of objects I need to use to set
these values ?
Thank you.
