请问这是什么错误

Question

package  com.solve.myjsp;
import java.sql.*;
public class connbean{
private String forname="sun.jdbc.odbc.JdbcOdbcDriver";
private String url="jdbc:odbc:solve"; 
String sql="select * from ZH_SZJZ";
public Statement stmt;
public Connection conn;
public ResultSet rs;
public void connbean(){
try{
     Class.forName(forname);
    conn= DriverManager.getConnection(url,"sa","da");
   
    stmt=conn.createStatement();
}catch(ClassNotFoundException e){

}catch(SQLException e1){
}
}
public ResultSet getresult(){
try{rs=stmt.executeQuery(sql);}
catch(SQLException e){
}
return rs;
}
    
}
jsp里史<jsp:useBean id="conn1" class="com.solve.myjsp.connbean" />
<%ResultSet rs1=conn1.getresult();%>

Answer 1

public void connbean(){
去掉void
try{
     Class.forName(forname);
    conn= DriverManager.getConnection(url,"sa","da");
   
    stmt=conn.createStatement();
}catch(ClassNotFoundException e){

}catch(SQLException e1){
}
}

Answer 2

好像是ＣＡＳＴ的问题．
jsp里试试<%java.sql.ResultSet rs1=conn1.getresult();%>

Answer 3

改了后是可以的tomcat重起试试也可以先测一下bean
