Re: problem!

I have seen the 503 before.  What has happened is you have some servlet
configured to "Load at Startup".  Something about this servlet is broke,
either it's init( ) method incurred an unhandled exception; it's classfile
got deleted, etc.  Anyway, when this happens to a servlet configured this
way, then ANY access to any servlet/jsp/html within the same webapp will
fail with a 503 error code.  This is true even if there is nothing wrong
with the resource itself.

You can circumvent this temporarily by configuring the failing servlet to
no Load at Startup.  But the real solution is to fix whatever exception
that servlet is incurring.  There should be more information in the app
server's stdout/stderr file (located in
/QIBM/UserData/WebASAdv/default/logs/ by default) that provides more
information about the exception.
