Thisis the error:

these are the jars dat i have included till now

hibernate3.jar
hibernate-testing.jar
asm.jar
cglib-2.1.3.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
hibernate3.jar
jta.jar
junit.jar
sqljdbc4.jar
mysql-connector-java-5.1.11-bin.jar
mysql-connector-java-3.1.12.jar
log4j-1.2.15.jar
slf4j-api-1.5.8.jar
slf4j-log4j12-1.0.jar

Also can u tell me on which all factors does the selection of these jars depend ?

You're having a problem with logging here: the api and the impl should use the exact same version


that's also going to give you more trouble later, choose one not both

Is hibernate3.jar really a duplicate on classpath?

As I see you're having much trouble in identifying and selecting the jar, I'd suggest you to study how to use maven2 which is a powerful tool to handle this for you and correctly identify what to put on classpath, and also shows the dependency tree to answer your last question; all hibernate libs are maven friendly.

Also this is not the right forum for such questions, this is about hibernate Search, Validator and Shards
