Duplicate key value violates unique constraint

I am using hibernate, jboss6.0.final and I am getting following exception:

ERROR: duplicate key value violates unique constraint "tablename"
  Detail: Key (pkey)=(11929) already exists.
2011-07-18 06:28:04,373 ERROR [org.hibernate.event.def.AbstractFlushingEventListener] (http-69.89.2.245-8080-1) Could not synchronize database state with session: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update
    at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:94) [:3.6.0.Final]
    at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) [

I have excluded the jta.jar from hibernate-core.jar in my pom.xml. What is the reason?

The record you're trying to insert already exists. You need to use update or saveOrUpdate.

This exception is because you insert already persisted bean.
