Supported Java communication protocols

The Java Record Replay (JRR) protocol enables full VuGen functionality when recording a script on a Java application or applet. VuGen creates a script in pure Java and enhances it with Java-specific functions.

VuGen supports a variety of different communication protocols for Java applications:

Protocol Description
RMI
  • See Working with RMI
  • CORBA
  • See Working with CORBA
  • JACADA
  • See Working with Jacada
  • JMS (Java Message Service). Supports messaging between computers in a network
    JDBC (Java Database Connectivity) Used for defining how a client may access a database

    VuGen's built-in support for the Java protocols utilizes hook files to define how different classes communicate with each other. By default, VuGen only records client side activity in a script, which then emulates the load on the server. You must edit the hook file to change the actions recorded by VuGen.

    Note: If you are recording a script that does not use one of the supported protocols above, you must define your own hook file. Otherwise your Vuser script will be empty.
