RE: Re: RE: Re: several connections to shark

Hi,

Your answer did remind me of something that I have read long time ago (I think was also one of your answers to other list member)… and that was forgotten.

Many thanks, for your quick answer.

So I’m using shark as a library, how can I terminate shark correctly?

Thanks one more time.

Regards,

Pedro

Hi,

shark can be embedded into your Java application in which case it is not a server, it is used directly as a library.
Shark project also comes with several "server" deployments: it can be deployed as CORBA service, Web service or EJB service.

So you can write your (separate) application to access shark and to make connections to it.

Hello,

The example that you gave, allows to make several connections inside the same java program right?

It’s is possible to have the server running independently in one java “program” and my program (running separately)   just makes a connection to the server??

Regards and thanks,

Pedro

Hi,

this is fairly simple, e.g. to establish 2 connections:

wmci = new WMConnectInfo("test","","","");

sharkc = Shark.getInstance().getSharkConnection();

sharkc.connect(wmci);

sh = sharkc.getSessionHandle();

wmci2 = new WMConnectInfo("secondtest","","","");

sharkc2 = Shark.getInstance().getSharkConnection();

sharkc2.connect(wmci2);

sh2 = sharkc2.getSessionHandle();

Hello again,

I’m now facing a different situation.

In the papers that I have read about OMG and WFMC its possible to have several connections to shark.

Currently I can only establish one, with the code transcribed above.

What I would like to do:

                Start shark from simple java program that does nothing else. Let’s call it “SERVER”.

After that, one or several, entities of my main program will establish a connection to the “SERVER”.

Can someone help me with this subject?
