Answer 1

你的JDK或者Tomcat路径出了问题。你按路径检查下看看能不能找到。

Answer 2

我都重新装过的刚才那个是说得不是太准确，上面的错误信息是在启动服务器的时候出现的页面可以加载出来，但是在进行操作的时候就会报下面的异常javax.servlet.ServletException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection

Answer 3

打不开session或事务，你把代码贴出来看看

Answer 4

public Users getUser(String userName, String password,String codeName) {
try{
List<Users> userList=( List<Users>) this.getHibernateTemplate()
.find("from Users where username=? and userpwd=?",

if(null!=userList&&userList.size()==1){
//判断输入用户的角色名与角色表中的名称是否相同
//如果相同则返回用户
if(userList.get(0).getCode().contains(codeList.get(0))){
return userList.get(0);
}
}
}catch(Exception ee){
log.debug(ee.getMessage());
System.out.println("登陆失败！");
}
　　　　}public ActionForward doLogin(ActionMapping mapping, ActionForm form,

Answer 5

lz，这段代码没问题。问题应该出现在你的sessionfactory中。
Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Cannot open connection 
很明打不开connection

Answer 7

org.com.jing.orm.Power.fatherid
这个类里的这个属性好像发生的异常。

Answer 8

如果用Hibernate与数据库 Microsoft SQLServer 2000组合，在取子表集合的时候会抛出异常:
org.hibernate.exception.GenericJDBCException: could not initialize a collection:
和异常:SQL Server 2000 Driver for JDBC ResultSet can not re-read row data for column 1
这是因为微软的Microsoft SQLServer驱动有以下问题:
1、如果采用jdbc-odbc驱动，那么就必须按照查询顺序来一次读取（不论有没有image或text类型）2、如果采用微软提供的ms sql server jdbc driver，如果查询语句中，不存在image或text类型字段，那么可以按照无序获取3、如果采用微软提供的ms sql server jdbc driver，如果查询语句中，存在image或text类型字段，那么就必须按照顺序读取，否则就会报告Driver]ResultSet can not re-read row data for column之类的错误4、如果想不查询语句中有没有image或text类型字段，都可以不按照顺序获取，或重复获取。
Hibernate在取子表集合时，它的不是按查询顺序来一次读取的，所以会抛出上述异常.
解决办法:
更换Microsoft SQLServer驱动，我现在用的是jtds-1.2.jar,这个驱动包大家可以到CSDN下载.
它的连接字符串是:jdbc:jtds:sqlserver://localhost:1433;DatabaseName=数据库名
驱动类:net.sourceforge.jtds.jdbc.Driver,
问题解决了. 本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/chinahgf/archive/2008/03/18/2193513.aspx
