Hi Team,

We have started using hibernate-memcached component as Second Level Cache in our hibernate projects.

Since this is a plugin kind of configuraiton, we are note able just exact perfomance benefits, would like to know if hibernate-memcched is a proven framework to use as Second Level Cache. Becasue, i dont see frequent updates are happening to the thirdpary component and i dont see any moment in teh http://code.google.com/p/hibernate-memcached/ site.

Any suggestion woudl help me greatly, i am okay to switch to a different caching emcanism if this is not a good one.


I am often getting the below exception:

org.hibernate.exception.GenericJDBCException: could not inspect JDBC autocommit mode
ploaduser.txt:Caused by: org.hibernate.exception.GenericJDBCException: could not inspect JDBC autocommit mode
ploaduser.txt: at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:91)
