I have the following jars in my classpath:
ant-antlr-1.6.3.jar
asm.jar
asm-attrs.jar
cglib-2.1.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.jar
jta.jar
log4j-1.2.8.jar
hibernate3.jar
hsqldb.jar
mysql-connector-java-3.1.14-bin.jar

Do I need anyother jar?
These jars were mentioned in the hibernate tutorial.

Query qr=session.createQuery("select userID from Users" );
where Users is a simple java bean mapped to the table (users) in MySQL.

Whenever I call the function containing the line,
I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: antlr/ANTLRException
