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:
|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.
