Directory Contents

• Dictionary.java


The Dictionary interface written in Java.

• DictionaryClient.java


This is the Dictionary client. It binds to the Dictionary Server and puts a variety of data types into the Dictionary. the client passes a string, a vector, creates a hash table and a vector, fills them in with words and passes the built in types into the CORBA Dictionary. This shows the mixing and matching of built-in Java types which are all passed using Java serialization.

• DictionaryServer.java


This is the Dictionary Server. The dictionary is implemented using a Java hash table. The benefit of using the Java hash table is that each of the methods that the Dictionary supports can be simply implemented as a one-line call to the underlying hash table.

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 "Dictionary.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 Dictionary server using the command:

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

Next,

prompt> vbj DictionaryClient
