I am trying to interface one SmallTalk process with a Java process.
Can you please help me by giving the appropriate JAVA API/class/package to enable this Inter-process communication or Can you provide some JAVA sample code which has ability to do the Inter-process communication.
Since Sun's mantra has been "the network is the computer" you will find lots of possible communication methods.
In addition to Henry's suggestions you could: communicate using email communicate using messaging communicate using HTTP requests and the servlet API (SOAP and XML-RPC come to mind) and probably a lot more.
Probably the critical questions have to do with the communication facillities in your SmallTalk installation. If this was my problem I would be searching the smalltalk docs for topics like XML-RPC and SOAP. Bill
