The List example

The List example illustrates the use of the Caffeine compiler and pass_by_value of complex types.

• Pass complex types by value

Directory Contents

• List.java


The List interface written in Java. Note that this interface could both have been written using standard IDL.

• ListUtility.java


This is the ListUtility interface. It has methods to manipulate the linked list defined above in List.java.

• ListClient.java


This is the ListClient program which binds to the ListServer, creates lists, and calls operations on them.

• ListServer.java


This is the ListServer, implementing the length, reverse(), sort methods.

Building this example

This project has to be build in two steps.

1. Make Dictionary.java: select the Dictionary.java node in the project tree and click Build | Make "ListUtility.java". This process will invoke the Caffeine compiler which will also generate java files that are going to be needed by the other java classes in this project, which is why the build has to be done in two steps.
2. Make the whole project.

Running this example

To run this example, first make sure that the VisiBroker Smart Agent (osagent executable) is running on your network. Then start the ListServer using the command:

prompt> vbj ListServer  & 
(start vbj ListServer on Windows)
// make the server run in the background

Next,

prompt> vbj ListClient
