jsp的createStatement()出问题，一直没法解决
org.apache.jasper.JasperException: Exception in JSP: /test.jsp:7

4: <%
5: DBConnection DBConn = new DBConnection();
6: Connection Conn = DBConn.getConn();
7: Statement stmt = Conn.createStatement();
8: //String sql = "select * from BigClass order by BigClassID ";
9: //ResultSet rs = stmt.executeQuery(sql);
10: %>

只要把第七句注释了，就正常;加上马上就是这么个反应。
什么问题？

[解决办法]
Conn这个是不是null啊

[解决办法]
加个异常处理看看: <%
try{
5: DBConnection DBConn = new DBConnection();
6: Connection Conn = DBConn.getConn();
7: Statement stmt = Conn.createStatement();
8: //String sql = "select * from BigClass order by BigClassID ";
9: //ResultSet rs = stmt.executeQuery(sql);
}catch(Exception ex){
ex.printstacktrace();}
10: %>
