游标该如何设置？

[HowHowHow]

<%@ page contentType="text/html;charset=gb2312" language="java" import="java.sql.*,java.io.*,java.util.*"%>
<%
Connection con=null;
int scrollType=ResultSet.TYPE_SCROLL_INSENSITIVE;
int concurType=ResultSet.CONCUR_READ_ONLY;
Class.forName("COM.ibm.db2.jdbc.net.DB2Driver");
con=DriverManager.getConnection("jdbc:db2://xxx.xx.xxx.xx/xxx","xxx","xxx");
Statement statement=con.createStatement(scrollType,concurType);
%>

为什么出错？
Error 500: Server caught unhandled exception from servlet [JSP 1.1 Processor]: COM/ibm/db2/jdbc/net/DB2Connection.createStatement

老哥
Class.forName("COM.ibm.db2.jdbc.net.DB2Driver");
应该写成Class.forName("COM.ibm.db2.jdbc.net.DB2Driver").newInstance();吧？

但我只要把
Statement statement=con.createStatement(scrollType,concurType);
改为
Statement statement=con.createStatement();
就不会出错呀？

[ls]

jdbc不支持

[HowHowHow]

我用的是WebSphere 4.0和DB2 7
不支持吗？
怎么用rs.getInt(1)等也出错，

怎么才能检查JDBC支持的游标类型
