关于JSP里查询语句SQL的一个简单问题!help!
源代码:

<%Class.forName( "com.ibm.as400.access.AS400JDBCDriver ").newInstance();  
//连接数据库
String   url= "jdbc:AS400://A46cm:23/DATA1 ";  
String   user= " ";  
String   password= " ";  
Connection   conn=   DriverManager.getConnection(url,user,password);  
Statement   stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

String   sql1= "select   *   from   table1 ";
String   sql2= "select   *   from   table2 ";

ResultSet   rs1=stmt.executeQuery(sql1);
ResultSet   rs2=stmt.executeQuery(sql2);

while(rs1.next())   {%>  
<table>
<tr>
<td>
Total   Qty: <%=rs1.getString( "T1 ")%>  
</td> </tr>

<%}%>  

<%
if(!rs1.next())
out.print( "没有找到! ");%>  

<%rs1.close();  

stmt.close();  

conn.close();  

%>  


我在jsp里连接数据库,然后查询database,一开始只定义一个sql1语句查询table1表单,可以运行,后来加了一句,sql2语句,想查询table2的表单,就报错误:
javax.servlet.ServletException:   Cursor   state   not   valid.
这是咋回事阿?难道一个jsp里只能有查一个表单?
Help!!!!!!


------解决方案--------------------
Statement stmt2=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

ResultSet rs2=stmt2.executeQuery(sql2);
