关于ejb事务回滚的问题！

Question

在会话bean里，异常部分加入回滚代码即可。

也可以,在ejb-jar文件中设置一下.<assembly-descriptor>
<container-transaction>
<method>
<ejb-name>JuchuProcInvoker</ejb-name>
<method-intf>Remote</method-intf>
<method-name>*</method-name>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>

Answer 2

public void afterCompletion(boolean committed){
System.out.println("afterCompletion:"+committed);
if (committed ==false){
try {
checkingBalance =selectChecking();
savingBalance =selectSaving();
}catch (SQLException ex){
throw new EJBException("afterCompletion SQLException:
"+ex.getMessage());
}
}
}
