You didn't say what 'entry' is, but if it is a String or some primitive you
can just pass it as another parameter.
<s:url action='DeleteEntryForm'>
<s:param name="name" value="%{goalToAchieve.owner.fullName}" />
<s:param name="entry" value="%{entry}" />
</s:url>
Usually, every database entity object has an 'id' property (primary key) and
you would just pass the id as a parameter so your action can find the object
in the database.
In you browser do a view source on the page to ensure the url is being
generated correctly with the params you are expecting.
