sw->thoriredd: the fact that xModifiable.setModified(false) doesn't return lets
me thinks that the office isn't properly working at this stage anymore, maybe
because of something that has been done beforehand.
Generally I would avoid to use "xComponent.dispose" to close the document and
instead query xCloseable from your xModel and use the method
"xCloseable.close(true)" instead. This way the possibility of a
CloseVetoException is given in case the document can't be closed for whatever
reason.
Could you check if changing your code this way avoids the "freeze" of your program ?

I try to us XCloseable 
                com.sun.star.util.XCloseable
xClose=(com.sun.star.util.XCloseable)UnoRuntime.queryInterface(
                        com.sun.star.util.XCloseable.class,xModel);
xClose.close(true); 
instead of 
xComponent.dispose(); 
but the problem remain..
The very strange thing is that the first time that i run the application after
the start of OO, all is ok, then at the second or third,ecc...(it is random) i
can obtain 2 different situations: I don't obtain any error and the process
remains suspend.., or the process goes down with a DisposedException..

Sometimes openoffice crash and obtain this error_log that i have attached

Created attachment 34959 [details]
Error Log of OO crash

sw->thoriredd: The log you send only tells me that your OOo1.1.4 crashed
somewhere in writer ;-) ... to understand the scenario a wee bit better could
you elaborate what exactly you are doing ? ... does your program load a
document, manupilate it and then closes it again ? ... If so does it happen with
a special document are with every you used so far ? ... If it is only one
document does the office survive loading it via UI ? ... If the UI manages to
load it, do you load it hidden when using the API and how is the office started
"headless" ? ... questions over questions :-) ... And one final one ... does the
problem still appear with OOo2.0.2 ?

I try to explain better what my macro does:
First of all it loads a blank document and creates headers,footers and sections.
Then it imports about 20 rtf files and before everyone it creates a table with 4
column and 1 row.
Then the macro inserts about 2-5 images (anchored at paragraph or as character)
Finally, the macro replaces some string in the document, and then save and close
the document.
However the document is generated correctly even though the error.
The soffice process is started before the macro run, with the parameter
-headless and -minimize; during the execution of the macro, the document appear
on the display.
I have the same error also with OOo2.0.2.
With this changes to the code:
...
               // xModify.setModified(false);
                com.sun.star.util.XCloseable
xCloseM=(com.sun.star.util.XCloseable)UnoRuntime.queryInterface(
                        com.sun.star.util.XCloseable.class,xModel);
                com.sun.star.util.XCloseable
xCloseC=(com.sun.star.util.XCloseable)UnoRuntime.queryInterface(
                        com.sun.star.util.XCloseable.class,xComponent);

                try {
                    xCloseM.close(true);
                    xCloseC.close(true);
                }
                catch  (com.sun.star.util.CloseVetoException exCloseVeto)
                {
                     exCloseVeto.printStackTrace();
                }

...
I obtain a DisposeException and that, in case of error, the office goes down,
but don't crash..

sw->thoriredd: quite a lot of things your program does :-) ... briefly to the
changed code ... no reason to get XCloseable twice this way you will always get
a DisposedException in the line with the second "close" call since the object is
already disposed at this point. 
The original issue stated that you freeze when calling
"xModifiable.setModified(false)" ... since you commented that out does it now
freeze within the first "xCloseable.close(true)" ?

With or without the code xModifiable.setModified(false) i obtain the same error..
I have commented this line because i save the document before in the code.
I cancel the second xCloseable.close(true) but the result doesn't change.. and i
obtain always the DisposedException when OpenOffice goes down..

sw->thoriredd: I try to understand the behaviour ... maybe my brain doesn't work
properly at the moment ;-) ... originally you had

xModifiable.setModified(false);
xComponent.dispose();

and sometimes your program stopped at the first call and you had to kill the
office manually which will no doubt raise a DisposedException in the dispose()
call because the office is gone.

Now you only have 

xCloseable.close(true)

what happens now ... does it sometimes freeze in this call and you have to kill
the office manually followed by the DisposedException ... or do you always get a
DisposedException when calling close(true) now ?

I try to be more clear now:
The program doesn't stop at the first call, but at the second or third or fourth
call.
I don't kill the office manually, when the execution of the macro is on the
line-code xCloseable.close(true) it remains some second, and then it goes down!
and when this happened, i have the DisposedException return on the Apache log...
The only change between the first and the second version of my code, is that
don't happened that office freeze and display the window of "Send Error"...
I hope that now the situation is more clear..

I don't know if it is a good thing, but now, i obtain the same error also on the
first call :-) , the code that i use to save and close now is this:
XStorable
xstorable=(XStorable)UnoRuntime.queryInterface(XStorable.class,xComponent);
               PropertyValue[] storeProps=new PropertyValue[0];
               xstorable.storeAsURL(url+".sxw",storeProps);
               //System.gc();         

           xstorable.store();
           XModel xModel=(XModel)UnoRuntime.queryInterface(XModel.class,xComponent);

            if(xModel!=null)
            {
                com.sun.star.util.XModifiable xModify =
(com.sun.star.util.XModifiable)UnoRuntime.queryInterface(
                    com.sun.star.util.XModifiable.class,

                xClose.close(true);
            }
            else
            {
                com.sun.star.frame.XController xController =
(com.sun.star.frame.XController)UnoRuntime.queryInterface(
                    com.sun.star.frame.XController.class,
                    xComponent);

                if(xController!=null)
                {
                    if(xController.suspend(true)==true)
                        com.sun.star.frame.XFrame xFrame = xController.getFrame();
                        xFrame.dispose();
                    }
                }
            }
        }
        catch (com.sun.star.io.IOException exIO)
        {
            System.out.println("ECC2");
            exIO.printStackTrace(System.out);
        }
        catch(com.sun.star.lang.DisposedException exDisposed)
        {
            System.out.println("ECC3");
            exDisposed.printStackTrace();
        }
        catch(com.sun.star.uno.RuntimeException exRuntime)
        {
            System.out.println("ECC4");
            exRuntime.printStackTrace();
        }
        catch (Exception e )
        {
            System.out.println("ECC5");
            e.printStackTrace(System.out);
        }
The error is the same, in the line xClose.close(true) office wait 2-3 second,
then goes down, and return the DisposedException...

sw->thoriredd: reproducible is good, that it happens at all not so good ;-)
When xCloseable.close() throws a DisposedException there are good chances that
the document you want to close or the office at all isn't there anymore.
There are two things I'd like you to do ... firstly open an arbitrary empty
document which you keep open to ensure that your "headless" office doesn't shut
down after the last document was closed ... if this doesn't help please secondly
strip your program down and attach the essentiels to this issue so that I can
reproduce it two ... hopefully we so can figure out which part of the things you
do in your program causes the problems.

Ok, i think that i have found where is the problem: xCloseable.close() crash
only when i try to insert an image in the footer..
This is the method that i use:

The first part of the method is used to count how many section(and so now many
styles) will be in the final document, then i insert the number of the page in
the center of the footer and with a \t i insert the image in the bottom-right
corner of the page..
If i don't insert the image, all is ok...
The very "fun" thing is that, if i run the program on a Window platform with my
local open_office, there aren't any kind of problem..the method XClose.close()
run correctly, and the office document close correctly (with the right image in
the footer)

what does "newurl" contain when you do the remote run ... is it a valid url or
null ?

newurl contain a string like this:

vnd.sun.star.GraphicObject:1000000000000176000000BD1F52B828

I think this is the reference internal to the image...

sw->thoriredd: mmm that is really strange, since I don't have any problems
inserting graphics with different urls wherever I want and then close and save
the document ... so I thought maybe on the remote side (since you said it works
locally) the string might be accidently NULL which would kill the java-bridge
and with that the office ... doesn't seem to be that way ... can you provide a
working sample to make the bahaviour reproducible ?

All the objects are correctly istantiate, in fact the image is insert correctly
in the final document, the strings are not null. I found that the line that
bring office to crash during the call of the metod xClose.close() is this:

xCellText.insertTextContent(cellcursor,gContent, false); (There is another way
to insert an image?? i don't think so...)
It's difficult for me to make a working sample, because we extract the data from
a   database..

sw->thoriredd: mmmm ... none of the snippets you posted so far contains
insertion of graphics in text tables, but a quick check showed that this also
throws any exception when I try it ... to really get a clue what is going wrong
I'll need a running sample that reproduces the behaviour.

In the zip there is an example: now i explain to you how use it:
This is a web-application, so you must copy it in a webapps on Tomcat.
Then you must change the file config.properties that is in WEB-INF/classes in
this file you must modify this parameters:
test.portaO the port where OpenOffice run (in headless and minimize mode)
test.portaT the port of the Tomcat
test.host = the host name of the server where you run the web-application
test.server = the address on the file-system of the server
test.percorso = Don't change this
test.percorso_img= the address on the file-system of the server+path
MacroWeb/FileMacro/Bitmaps/ 

Then you can try the macro with http://hostname:port/MacroWeb/prova.jsp and
click on go to launch.

If you want the sourcecode is in the path WEB-INF/src 
In the path WEB-INF/lib there are the OO 1.1.4 library (this in the
OFFICE_HOME/program/classes)
I hope that you can try this!!!
The document that you will obtain is a simply version of the one that i generate
in my application(without the files RTF), but with the image in the footer that
bring xClose.close() to crash...

sw->thoriredd: after removing all references to the Oracle-jdbc calls and adding
a nuovo.bmp I manage to make it run and indeed the office dies prematurely as
soon as xCloseable.close() is called.

sw->mba: the created document can't be closed until I completely shut down the
web-server, even if I keep the document open in the java-code by commenting out
"xCloseable.close()" and close the document via UI after the servlet returns and
then close the document via UI the office dies without creating a crash report
... in the command line I see

So you have my same problem...is little comforting..:-)
I use the Jakarta Tomcat 5.0.28 and Sun Solaris 10, so how can proceed now?? I
suppose that i must wait for the OOo 2.0.4 (when it will be released?) There
isn't another way??

@sw:
Sorry but what means "can't be closed"? 
Does it refuse? Does it crash? From former comments I assume it's the latter but
please let me know if I'm right.

If it crashes: did you create a crash report?

I think that "can't be closed" means that OO don't close property calling the
method xClose.close(true), the document is created correctly, but OO crashes
when i try to invoke the method..

So to Stephan: can you provide a crash report?

seems to be a lot more work to do

There are any news??? 
This problem is mission-critical for our application...

No news; Stephan is no longer with us and until now nobody else had the time to
take over. Perhaps you can speed up things by describing shortly what needs to
be set up to reproduce the problem (as distilling this information out from the
issue surely is a tedious and longish procedure). Can we reproduce the problem
with a standalone Java application (did you try?) or do we need to have a Web
server installed (what most developer machines don't have).

Did you try the same with a recent OOo version?

There are any news??? 
This problem is mission-critical for our application...

Sorry...i post the same message two times...
I tried also with 2.1 but the problem is the same...
I have posted in a zip, an example of the issue, as i said time ago, the problem
is the image in the footer..
