 Posted: Mon Apr 24, 2006 10:29 am Post subject: Solution to close OOo connection (MessageDispatcher Thread) |
 |
|
Hello,
Many people close the jvm with system.exit but it is not the good solution. So I post this solution to close correctly the connection with OOo without system.exit or xDesktop.Termante().
The solution is in the XBridge service.
See the code to open or close a connection to OOo :

I find this solution in the snippets of openoffice.org :

Try with the document hidden, if it's not hidden, OOo wait the user close the window and so the application is not closed. Hidden is a property of the documùent when you open it.
I don't know but I think it's not the solution because OOo is running in server mod and so it must not be closed. If you open a connection like this, the jvm is closed normally and open office stay open. The only problem is OOo don't clean up open ressources but when it is launch in server mod, it is not possible to close it to clean ressources.
It's the better solution I find.
