十分钟在jb里面运行hibernate的简单例子。

为什么我换成ms-sql后就会出现这样的错误呢？
程序没有变过啊，只是jdbc改过了:(

不知错再那里。恳请帮忙！

确实和jdbc驱动有关系，我使用的是官方的最新的jdbc驱动就解决了这个问题。如果使用mm的jdbc好像就有问题。

谢谢楼主
已经解决了

在引用第三方库文件时不要导入log4j这个包

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

## to use JTATransactionFactory, Hibernate must be able to locate the UserTransaction in JNDI

## you do NOT need this setting if you specify hibernate.transaction.manager_lookup_class

#jta.UserTransaction jta/usertransaction
#jta.UserTransaction javax.transaction.UserTransaction
#jta.UserTransaction UserTransaction


## to use JCS caching with JTA, Hibernate must be able to obtain the JTA TransactionManager

## set the JDBC fetch size

#hibernate.jdbc.fetch_size 25


## set the maximum JDBC 2 batch size (a nonzero value enables batching)

hibernate.jdbc.batch_size 0


## enable use of JDBC 2 scrollable ResultSets (specifying a Dialect will cause Hibernate to use a sensible default)

#hibernate.jdbc.use_scrollable_resultset true

## use JDBC 3 PreparedStatement.getGeneratedKeys to get the identifier of an inserted row

### JNDI ###
############

## specify a JNDI name for the SessionFactory

#hibernate.session_factory_name hibernate/session_factory


## Hibernate uses JNDI to bind a name to a SessionFactory and to look up the JTA UserTransaction;
## if hibernate.jndi.* are not specified, Hibernate will use the default InitialContext() which
## is the best approach in an application server

#file system
#hibernate.jndi.class com.sun.jndi.fscontext.RefFSContextFactory
#hibernate.jndi.url file:/

#WebSphere
#hibernate.jndi.class com.ibm.websphere.naming.WsnInitialContextFactory
#hibernate.jndi.url iiop://localhost:900/
