Thanks Stephan for your reply.
Overview - our system is for newspapers. We have a Java application
which rives OpenOffice. The ad taker uses our Java application, which
has multiple tabs. On one tab is OpenOffice, we size and move OpenOffice
so it stays within our window. The user enters the ad text in
OpenOffice. On the other tabs (Java panes) the user enters customer
info, billing, credit info etc. When the user first opens/creates an ad
we:
We add ourselves to XEventListener.
We setup our own service to talk to OO and for OO to talk to the Java
side.
We get the following interfaces
XTextDocument
XMultiServiceFactory
XTextFieldsSupplier
XDrawPageSupplier
XStyleFamiliesSupplier
XPrintable
XModifiable
XStorable
XRefreshable
XNameAccess
XWordCursor
XParagraphCursor
XViewCursor
XLineCursor
We use these same interfaces during the session of the ad. We do a lot
of getPropertySet and setPropertyValue. We make calls from Java into OO
macros, we respond to events, and we save the document via an OO macro.
This all works fine most of the time.
There seems to be cases (especially when the computer is busy) when we
get the exceptions. Once we start getting the exceptions, we do not
recover.

Regarding, "What requests are you sending exactly?"
For
com.sun.star.lib.uno.protocols.urp.Unmarshal.readboolean -
unexpected:java.io.EOFException
We called XModifiable.isModified ()
For
com.sun.star.io.IOException: java.net.SocketException: Socket closed
XPropertySet pagePropertySet =
getPropertySet(pageStyles.getByName("Standard"));
pagePropertySet.setPropertyValue("Width", pageWidth);
For
java_remote_bridge
[EMAIL PROTECTED] is
disposed
We called XModifiable.isModified ()
Regarding, "Do you have an idea how many synchronous UNO requests from
your local Java side are outstanding," no but there could be several.
Regarding, "...remote side of the bridge is closing the connection,"
this is very interesting. Why is it closing the connection? Is there a
way to keep the connection open until we are finished?

Hm, this means the remote side of the bridge is closing the connection
while the local side of the bridge thinks it still has to read data. Do
you have an idea how many synchronous UNO requests from your local Java
side are outstanding (have not yet received a reply from the remote OOo
side) when the exception occurs---none, one (i.e., on a single Java
thread), or multiple (i.e., on multiple Java threads simultaneously)?
What requests are you sending exactly?
