Distributed systems<br />
possible without a netscape package. Is that true? Is there a simple implementation<br />
of the same functionality (source code) which I could incorporate in my applet?<br />
Answer: Those Netscape packages are part of the current VM of both Microsoft IE 4+<br />
and Netscape 4+. So, by adding the MAYSCRIPT tag to your Applet declaration, in<br />
the <strong>Java</strong> code you can obtain a handle to the document and call functions in it.<br />

Q: I'm researching methods by which one JVM can interact with another JVM,<br />
which is running on the same machine.<br />
I know that there are various network models, which can be applied if a JVM needs<br />
to talk to another one across a network, but in addition to these (which could I guess<br />
be applied to JVMs on the same machine) I wondered if you knew of a system of<br />
JVM communication that requires less system resources, where the JVMs are both<br />
running on the same system.<br />
Answer: CORBA, RMI, HTTP, sockets....<br />
But if you have no TCP/IP stack on your platform, so for Windows it could be<br />

Q: I have a question about sending a reference to the object via the socket...<br />
I have a question about sending a reference to the object via the socket. Two threads<br />
are communicating via sockets running on the same machine. I don't need to send<br />
the whole object, but I need to send just<br />
a reference.<br />
Does anyone knows how to do that?<br />
Answer: Reference to an Object? A reference is only valid within the same memory<br />
space! If you want to be able to invoke methods on an object remotely, then you will<br />
need to use a remote technology like RMI, CORBA, or some such.<br />
