为什么执行总进入catch部分

[wjj8246]

Connection Conn;
ResultSet Rs;
Statement Stmt;

String sDBDriver="oracle.jdbc.driver.OracleDriver";
String sConnStr="jdbc:odbc:Jsp";
try
{
Class.forName(sDBDriver);
Conn=DriverManager.getConnection(sConnStr);
Stmt=Conn.createStatement();
ResultSet rs=Stmt.executeQuery("select * from Jsp");
String tt1,tt2;
while(rs.next())
{
tt1=rs.getString("UserName") ;
tt2=rs.getString("UserPwd");
out.println(tt1+tt2);
}
}
catch(Exception e)
{
out.print(e.getMessage()) ;
}

改为如下试试：
String sDBDriver="oracle.jdbc.driver.OracleDriver";
String sConnStr="jdbc:odbc:Jsp";
try
{
Class.forName(sDBDriver);
Connection Conn=DriverManager.getConnection(sConnStr);
Statement Stmt=Conn.createStatement();
ResultSet rs=Stmt.executeQuery("select * from Jsp");
String tt1,tt2;
tt1 = "";
tt2 = "";
while(rs.next())
{
tt1=rs.getString("UserName") ;
tt2=rs.getString("UserPwd");
out.println(tt1+tt2);
}
}
catch(Exception e)
{
out.print(e.getMessage()) ;
}
