How to grant that OOo is running? (Java)

[Trinkler]

Hello again,

I integrated some handles with OOo - Documents in my JavaApplication...

The first time i granted that OOo is up by launching it
on startup in -invisible mode during launch of my application.

But now I face the problem, that some users close the complete
Office after viewing one document.
The Javaapp is processing on and tries to connect to the Office
the next time a document was requested ... BUT there is no listening office anymore

I tried to initalize a loop requesting access to a remoteServiceManager before i want real access, but I despaired
catching the thousandth ConnectionException and others.
I only want to check if OOo is running and listening in an easy way.

Maybe anyone has a nice solution or want to give me a kick to get me on the right way ?

Hi there, here is a little script (in Python) that checks if OpenOffice is running, and if not start it with the appropriate parameters.

def CheckAppRun( chknam ):

k = os.popen('ps -e','r',1000)

h = k.read(1000)

l = ''

while h:

h = k.read(1000)

l += h

k.close()



try:

l.index(chknam)

Gevonden = True

except: Gevonden=False



return Gevonden



def StartOO(wppgmdir):

if os.name in ('dos','nt','xp'):

pass

elif os.name == 'posix':

if not CheckAppRun('soffice.bin'):

print wppgmdir

os.spawnv(os.P_NOWAIT, wppgmdir, [wppgmdir,'-accept=socket,host=localhost,port=2002;urp;'])

time.sleep(13)


The sleep is to make sure that OO has initialized and is ready to accept connections.

Hope this helps....


Cheers,
Dick

Many Thanks for your script

But, finally I didn't use it, cause I had an idea while reading your post...

Now I'm trying to create a socket connection at the officeport and return a "status"-int.
If a BindException occurs - status "launched" is returned (the Exception catched).
Otherwise (the connection has been created) status "not launched" is returned ... after closing the socket I execute OOo.
Now I'm looping round until i get the status "launched" returned by the function.

you can try "telnet <oohost> 8100"
if oo is listening, telnet will be accepted.
