public class SelectorASTFactory

extends antlr.ASTFactory

This class was created to override the 4 methods in antlr.ASTFactory that use Class.forName(java.lang.String). In the case of interaction with OpenJMS, the ClassLoader for the Factory class must not be higher in the tree than the OpenJMS classes. In the case of Weblogic 8.1 SP3, some antlr classes, including ASTFactory are encapsulated in the weblogic.jar, the ClassLoader on the antlr.ASTFactory class is the System ClassLoader. If you have openjms.jar in your EAR or WAR files, the antlr.ASTFactory class will not be able to find the OpenJMS classes when it is doing a Class.forName to load them.
