Two values on "input" attribute
Hi all:
I have a page validated with Validation Framework, but I can get that page from two diferent jsp inputs. When an error ocurs, the validator always turn me back to the same jsp input (the one especified) not matter which was the selected input. It is possible to set two values to "input" attribute in an ActionMapping?? Is there any other way to do something like that??
Best regards.

That always helps. So, your JSPs weren't compiling or something? It's
odd that it would "work", and yet, not work.

JSP compilation errors should show up right in the page. When something
like this happens, it's best to shutdown Tomcat, kill your "work"
directory and any expanded WAR files (usually killing the work dir does
that), and re-starting. It doesn't happen often, but sometimes TC goes
brain-dead and you just have to lobotomize it.

Certainly, and this is not the way it should work. I suspect that there
was a datestamp issue so it looked like the already-compiled version of
your JSP was more up-to-date than your new version.
Do a clean build and re-start and I think you'll find that TC will
report those compilation errors.

The simplest way to show the error in browser is to capture the OutputStream for the Response Object and stream the exception code,/desc/whatever back to the user as in this example-
response.getOutputStream().out("Exception text is "+excp.getMessage());
if you want to dress it up you can use css stylesheets/fonts/colors etc
Anyone else?

Re: Two values on "input" attribute
Posted by Thom Burnett <th...@gmail.com>.
First, I found my error and it's (of course) not in any of the code listed.
I had neglected the import statements in the jsp pages. :-(
So you can ignore this question but it does bring up another one.
Is there a way to get warnings or error messages when I've made a mistake
like this in the jsp?
In my build there was no compiler error or warning. Finding this type of
error by inspection is very time consuming.

Re: Two values on "input" attribute
Posted by Thom Burnett <th...@gmail.com>.
I tried this technique for my situation where several jsp pages contribute
to one ActionForm.
I'm getting the correct page selection behavior by my errors don't show up.
For the first page (the donation page) everything works very nicely.
For the second page (the honoree page) there's no trace of an error message.
That is, when (and only when) there's an error, the page will not continue
on to the next page but
the <html:errors/> tag seems to return no contents - that part of the
displayed page is blank.
I can't see any meaningful difference between the two pages. Is this a
question of where the ActionErrors instance is stored?

Yep; the other option is to set validate to false and call it manually,
then return the appropriate mapping in your action's execute, but the
above solution is probably easier.

Generally, this is done with two separate ActionMappings, like this:
<!-- submit to here from first.jsp -->
<action path="/path1"
type="MyAction"
name="MyFormBean"
validate="true"
scope="request"
input="/first.jsp">
...
</action>
<!-- submit to here from second.jsp -->
<action path="/path2"
type="MyAction"
name="MyFormBean"
validate="true"
scope="request"
input="/second.jsp">
...
</action>
You are doing the exact same thing in both cases, except that the
"input" attributes are different. The validation should be the same,
using the same form bean, etc.
Hope that helps,
