Thanks,
I am not explicitly calling the dispose method .
I would expect that dispose is called by a closing frame or something
like that.
Here is an overview of what I am doing.
1.opening a XSpreadsheetDocument (called temp_doc) by calling after
creating an object using
XMultiComponentFactory::createInstanceWithContext.
a.The document is a .ots file which opens as "Untitled 1".
2.XComponent temp_comp = UnoRuntime.queryInterface(XComponent.class,
temp_doc);
3.XStoreable store = UnoRuntime.queryInterface(XStoreable.class,
temp_comp);
a. exporting "Unititled 1", to an "ODF Spreadsheet", "StarOffice XML
(Calc)" format by setting the PropertyValue FilterName property. Once
the properties are set, I use XStoreable::stopToURL to save "Untitled
1" to "RawData.ods"
4.Then I close the document:
a.XModel model = UnoRuntime.queryInterface(XModel.class, document);
b.If model not null then, XCloseable closeable =
UnoRuntime.queryInterface(XCloseable.class, model);
i.closeable.close(); (This is always the case that happens)
c.If model null then, XComponent disposable =
UnoRuntime.queryInterface(Xcomponent.class, model);
i.disposable.dispose(); (My code never gets into this condition)
5.I then immediately open the file I exported in step three above by
creating a new XSpreadsheetDocument (called doc), using the same
methods defined in step one above, but when I do a
a.document = UnoRuntime.queryInterface(XpreadsheetDocument.class,
xCalcComponent);
I receive: com.sun.star.lang.DisposedExcpetion
at
com.sun.star.lib.uno.environments.remote.JobQueue.removeJob(JobQueue.java:
210)
Is it possible that xCalcComponent still belongs to temp_doc? That
would explain why it is disposed.
Otherwise, xCalcComponent should not be disposed directly after
loading. Even if the loading failed, it should not be created in the
first place and be NULL (well, an empty Reference, that contains NULL).
I would ask for any exceptions during the second loading, but
unfortunately OpenOffice throws a lot of exceptions that don't notify
any errors but are used for normal communication (don't ask)

Hopefully, this provides some context. Basically, I am opening an .ots
file, saving(exporting) it as an .ods file and closing it. Then I
open the .ods file so that I can populate the cells with data, but
right after loadComponentFromURL, I try to query the XComponent
returned from loadComponentFromURL to get the XSpreadsheetDocument.
That is when I get the DisposedException.

If you want to know who calls dispose() then you have to place a
breakpoint in the dispose() method of xCalcComponent.
If you want to know when dispose() is called then register a
com::sun::star::lang::XEventListener at the xCalcComponent object.
When it is disposed, it will call disposing(...) at the listener.
I am just not sure if it calls disposing() when the object is already
disposed when the listener is registered. Probably not.

Without knowing the context this can easily be a timing problem in a
multi-threaded environment: in AOO 3.3 some operation took longer
resulting in the dispose() call made a few milliseconds later (or
anything to this effect.)
