Hi,

I'm trying to use hibernate 2.1 beta 5 and I get the following error while it's starting. What could be the problem?

Hello,


pls look into the following settings in the hibernate.properties. I believe it got something to do with your hibernate.properties setting.

#################################
### Plugin ConnectionProvider ###
#################################

## use a custom ConnectionProvider (if not set, Hibernate will choose a built-in ConnectionProvider using hueristics)

hibernate.connection.provider_class net.sf.hibernate.connection.DriverManagerConnectionProvider
#hibernate.connection.provider_class net.sf.hibernate.connection.DatasourceConnectionProvider
#hibernate.connection.provider_class net.sf.hibernate.connection.C3P0ConnectionProvider
#hibernate.connection.provider_class net.sf.hibernate.connection.DBCPConnectionProvider
#hibernate.connection.provider_class net.sf.hibernate.connection.ProxoolConnectionProvider



#######################
### Transaction API ###
#######################

## the Transaction API abstracts application code from the underlying JTA or JDBC transactions

#hibernate.transaction.factory_class net.sf.hibernate.transaction.JTATransactionFactory
hibernate.transaction.factory_class net.sf.hibernate.transaction.JDBCTransactionFactory


## choose a cache implementation

hibernate.cache.provider_class net.sf.hibernate.cache.HashtableCacheProvider
#hibernate.cache.provider_class net.sf.ehcache.hibernate.Provider
#hibernate.cache.provider_class net.sf.hibernate.cache.TreeCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.OSCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.JCSCacheProvider
#hibernate.cache.provider_class net.sf.hibernate.cache.SwarmCacheProvider



## MySQL

hibernate.dialect net.sf.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class org.gjt.mm.mysql.Driver
hibernate.connection.driver_class com.mysql.jdbc.Driver
hibernate.connection.url jdbc:mysql://localhost/booky3,
hibernate.connection.username onix
hibernate.connection.password abracadabra

normal output would look something like this

Thanks

Same error. :(

Be sure that the file:

%orion_home%\lib\ehcache.jar

is in your classpath.

Are you using ehcache? JCS caching? The errors keep changing. :)

Sorry, I jumped the gun a bit.

I am actually not using caching.

I had just downloaded 2.1rc1, installed and executed app and received:

net.sf.hibernate.HibernateException: could not instantiate CacheProvider: net.sf.ehcache.hibernate.Provider

Searched for net.sf.ehcache.hibernate.Provider in the jar files and discovered that ehcache.jar was needed in my classpath for app to execute.

I am guessing that Hibernate pulls in net.sf.ehcache.hibernate.Provider by default.

I did not read the error messages deep enough to distinguish the differences in cache provider classes.

Anyway,

I searched for JcsCacheProvider and HashTableCacheProvider and found that they are both in Hibernate2.jar - at least in 2.1rc1.

Just a hunch, in your properties file, do you have the proper end-of-line charaters at the end of each record. Sometimes between unix and dos they can get botched up and have a hidden control code at the end of each line.

If the problem is the caching system, as it appears to be, you should try turning it off, initially. Does your hibernate.properties or hibernate.cfg.xml file contain an entry:

hibernate.cache.provider_class ?

If so, you should start that line with a pound sign to disable it (for now). That should take the errored section out of the loop so you can continue and get it working.

Regards,
David
