hibernate出的异常，请高手指点

[dinghw521]

我用的derby数据库，现在做的操作只是简单的用hibernate创建一个student的数据库，

hibernate.cfg.xml文件配置如下
<session-factory >

<property name="hibernate.connection.url">
jdbc:derby://localhost/stduent;create=true
</property>

<property name="hibernate.connection.driver_class">
org.apache.derby.jdbc.ClientDriver
</property>

<property name="hibernate.connection.username">
breeze
</property>

<property name="hibernate.connection.password">
breeze
</property>

<property name="hibernate.show_sql">
true
</property>

<property name="hibernate.use_outer_join">
true
</property>

<property name="hibernate.transaction.factory_class">
org.hibernate.transaction.JDBCTransactionFactory
</property>

<property name="dialect">org.hibernate.dialect.DerbyDialect</property>
<property name="c3p0.min_size">5</property>
<property name="c3p0.max_size">20</property>
<property name="c3p0.timeout">1800</property>
<property name="c3p0.max_statements">50</property>

<mapping resource="domain/Student.hbm.xml" />
</session-factory>

Student类只是一般的类，Student.hbm.xml配置没问题

是否是因为缺包呢？但是如果是的话应该是classnofound的异常啊

[dqsweet]

没有这样的方法错误
org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V

[year1234]

org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V
这个异常?
我没记错的话这是由于Spring2的asm-2.2.3.jar与Hibernate3的asm.jar的冲突造成的，需要删一个，删哪个我忘了。
再或者是asm.jar和cglib.jar的版本不对应，或者是因为用了cglib-full-XX.jar包含了asm.jar，如果用了cglib-full-xxx.jar再用asm.jar的话而且版本不一致。
所以个人认为你是多包了。
再网上搜一搜有关asm于cglib开头的包，看用哪个删哪个，好久没碰到包问题了，我也弄不好改留哪个包。
你用spring了？

你的jar包错误吧

按照楼上的方法试试吧。
