这道题应该怎么分析并改正错误呢？
分析程序并改错：谢谢大家！
public void open(String iJND)
{
Context context = new InitialContext();
DataSource dataSource = (DataSource)context.lookup(iJNDI);
connection = dataSource.getConnection();
stmt =
connection.createStatement (ResultSet.TYPE_SCROLL_INSENSITIVE,Result.CONCUR_UPDATABLE);
connection.close();
}

[解决办法]
你这个方法是不是要用来打开链接的啊？？

如果是的怎么又关了连接啊？？
connection.close();
[解决办法]
public void open(String iJND)throws Exception
{
Context context = new InitialContext();
DataSource dataSource = (DataSource)context.lookup(iJND);
java.sql.Connection connection = dataSource.getConnection();
Statement stmt =connection.createStatement (ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
connection.close();
}
