RE: STRUTS and EJB
Title: RE: STRUTS and EJB If a value object is used within the ActionForm for holding the form data, how should the html elements be named so that the data elements in the value object is automatically populated. Or should the data elements also reside in the ActionForm as separate fields, for which the setters and getters would go and get the information from the value object ?

The problem here is simply that I would not want to make another, exactly similar (except "extends ActionForm"), class for transporting the information to the EJB. Of course, I can do that, but I don't like the idea.

Using multiple ActionServlet's
Is anyone using multiple action servlets for one application. For example, if we have a main Action Servlet which delegates to other Action Servlets, each of which accomplish substantial amount of functionality. Any suggestions on the Pros and Cons of this architecture?

RE: Error messages
How were you able to access the "Collection" object containing the error
messages
from your extension?

Had to do similar stuff in the prototype I'm working on. We have error
icons that the users want displayed beside input fields that had validation
failures. So, the direction I leaned towards was a conditional tag if a
specific error is present. I could not find a tag provided with Struts
that let me do that, so I wrote one. There may have been a way to do it
with existing Struts logic tags.
example:
The tag code is similar to Struts ErrorTag. It would have been best to
inherit my tag class straight from Strut's error tag, but it didn't look
like it was factored in such a way as to make that possible (I believe the
code that looked for errors and assembled them into a collection was mixed
in the same method with the code that outputs the error text).
This is not a good final solution obviously, but it seems like some kind of
conditional error-presence-based-on-property tag is a good general approach
for this kind of problem.

Please
respond to
struts-user
Using ActionError and the html:ErrorTag I am able to display errors on the
page & also format the error messages using errorheader and
errorfooter.
Is there any way ( Tag or otherwise ) to highlight the field ( field label
&
the field itself) that the error refers to? e.g Displaying the label
and the textbox/checkbox in red.
Thanks
