JSP 连接SQL2000数据库问题
在JSP中我用JDBC-ODBC可以连接SQL2000，但是用JDBC 纯JAVA方式老是连接不是，错误为：

type Exception report

[解决办法]
java.lang.NullPointerException，空指针。把DBConn贴上来看看
[解决办法]
空指针 什么没有加载完全
[解决办法]
com.messboard.dbconn.DBConn.executeQuery(DBConn.java:81)
DBConn有问题
[解决办法]
SQL2000的SP3补丁打了没有？
JDBC补丁打了没有？

[解决办法]
应该是你bean没有遵守javabean的规范
[解决办法]
windows和sqlsever混合登陆!!!OK!!
