This might be the issue described at
<http://api.openoffice.org/servlets/ReadMsg?list=dev&msgNo=17855> and
turned down at
<http://www.openoffice.org/issues/show_bug.cgi?id=51323#desc4>: Once
doPost is done, the bridge will eventually be disposed when garbage
collection detects that there are no longer any live objects mapped
across it. If the Bootstrap.bootstrap of the next doPost comes at an
unfortunate time relative to garbage collection (whose timing will vary
with JVM details; which would explain why something that appears to work
fine in one scenario breaks in another), it will find an existing but
disposed bridge.
Various ways around this come to mind:
1 Change your code to do only one Bootstrap.bootstrap call, sharing the
returned context across doPost calls.
2 With issue 51323 (see above) fixed and eventually integrated, it
might be better if Bootstrap.bootstrap used an unnamed (i.e., fresh on
every call) bridge instead of a named one (i.e., reusing a bridge for
the lifetime of the involved soffice process). The drawback would be
that applications that now call Bootstrap.bootstrap multiple times but
rely on having only one bridge to soffice at any given time would then
have potentially many different bridges to soffice simultaneously, which
could be a resource problem.
3 Simply retry Bootstrap.bootstrap when it failed with a DisposedException.

We're working with soffice in a server. We use it for document creation and

Everything works fine under Tomcat Server however when we test the
application on real environment server which is Windows 2003 Server 64 bit
and Weblogic as application server we start getting the following
exception:

We're willing to solve this problem and help to debug it. Any ideas and help
