Hi He Feng Su,
Please try to use "com.sun.star.awt.AsyncCallback" service to get a
callback from the office main thread. You will need an own object
implementing com::sun::star::awt::XCallback interface. This object will
be provided to the com::sun::star::awt::XRequestCallback::addCallback()
call.
Just to explain the mechanics for better understanding. When java
application calls an UNO API method through a bridge, a new thread is
created on Office side and the method is executed in this thread.
When the XRequestCallback.addCallback() is called it sends a
notification with arguments to the main office thread and returns. After
a while the main thread calls XCallback::notify(), and if this method
does a call to the office back, the call is handled in the office main
thread.
Hope that helps.
Best regards,
Mikhail.

Thanks Mikhail!
The error is "0x8001010E The application called an interface that was
marshalled for a different thread ".
It's true that the OLE creation and activation happen in different
thread. I make use of "LoadComponentFromURL" UNO interface to load the
MS office document and it
happen in OOo non-main thread. And activation happens in OOo main
thread. How can I make sure the loading happen in OOo main thread by UNO
API calling on java side?

Re: [dev] OLE can not be activated in Windows OS after Java integration
------------------------------------------------------------------------
Hi,
If the object can be activated when the document is loaded in the normal
office, that would mean for me that a threading problem takes place. COM
does not support multi-threading ( as well as actually OOo ), so the
object should be activated from the same thread where it was created.
So I suspect that either the object is created in OOo non-main thread or
activated in OOo non-main thread, or both is done in two different OOo
non-main threads.
Which exactly error do you get from DoVerb() call?
Best regards,
Mikhail.
