  org.javaWebGen.data.WebLogicDataManager

All Implemented Interfaces:

DataManager

public class WebLogicDataManager
extends java.lang.Object
implements DataManager

Handles talking to Weblogic to get a database conneciton. only can be used inside the Weblogic container(IE inside a EJB, or JSP) sure will be more efficient than doing a JNDI lookup! This has not been tested much because I do not have WebLogic installed. And ony has been tried with an Oracle Database. Will use the built in weblogic connection pool WARNING this is Experimental(
