You can use Runtime.exec() to do this.

I understand this would start only a process with in this JVM and not another JVM?

It will start another projess and if that other process is, for example, "java SomeOtherProcess" then that other process will be running another instance of the JVM.

Hello,
In the JVM which I create using the Runtime.Exec method, I am not able to create a Connection to a database.
It throws a socket exception,
Failed Logon:com.jnetdirect.jsql.p: TCP/IP connection failed to host:java.net.SocketException: create (code=10106)

Any hints on this??

I am otherwise able to create a connection from the parent JVM i,e where I call Runtime.Exec.

Regards,
Ankur

But how does that matter??
I guess its not that only one client can connect at a particular port at on epoint in time !!
If that is the case then not more than one user would be able to connect to a database, but that does not happen.

I guess there is some other missing link here.
