In continuation to my mail below, I've tried running the compile option
using the beta release and here are my worries:
1. As mentioned in my previous mail, the compiler is unable to resolve
the referenced project classes. If I manually copy the referenced classes in
this project, the compiler runs fine.
2. Another thing regarding the Ant build option. As per the information
on the site, whenever I add the <taskdef .. to my build file, the jibx
target is the first task that runs even if it is not the first task that
should run. Any idea how can I suppress it to run after some default tasks,
like other ant tasks using "depends" attribute?
Thanks for your help and suggestions.

Hi Dennis -
Thanks for the reply, though I had tried running the compiler without using
the "extends" keyword first and after failing to make it work went for the
latter. I shall try working with the beta package and let you know if it
works as suggested by you.
On the "JIBX fails to find classes
that are included as dependent projects when I run the compile option" -
What I meant was that my project set up uses one project referring another
project as project dependency while setting class path for the project. Now
when I run the compiler on this dependent project, the referenced project
classes are not seen by the binding compiler and it throws off an error. One
of the Jibx users had replied that they use a workaround for this problem
and copy the dependent classes while running the Ant task by using unzip
task, which is not what I want.

Hi Anurag,
You probably don't actually need the extends="..." on the <mapping> in
this case. It seems like a lot of people use this unnecessarily, and
that sometimes creates problems. It's only really needed when you're
doing the equivalent of schema substitution groups, to implement
polymorphism. So try taking off the extends and see if that helps.
It's still a nasty bug in the binding compiler that this can occur at
all, though. Can you try this using the current JiBX 1.2 beta 1 test
release (in the "test" package on the download page
https://sourceforge.net/project/showfiles.php?group_id=69358)? I think
I'd encountered this issue and fixed it during the development of the
1.2 code, but I'll add in another check for the condition which could
cause this for the upcoming beta 2 release.
I don't understand your other issue, that "JIBX fails to find classes
that are included as dependent projects when I run the compile option".
Can you explain this in more detail?
