is it possible to determine the exact line-position in JSP files inside a Tag (or TagSupport Class)?
We need this to generate a unique, but don't variable ID, it must the same by every request. (Depending on the actual position in the JSP)
We've thought about the possibility to generate a ID over the StackTrace, but we aren't shure if this is a save method, cause every Webcontainer may translate the JSPs in a different way.
(It must work on every web- or j2ee-container)
IDs on different containers may be different, but in the same instance they must be exactly the same. (For every position, of course)
