package test;
import java.sql.*;

public class chatreg{
String sDBDriver = "org.gjt.mm.mysql.Driver";
String sConnStr = "jdbc:mysql://localhost/hc";
Connection conn = null;
ResultSet rs = null;

public chatreg() {
try {
Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e) {
System.err.println("chatreg(): " + e.getMessage());
}
}

public ResultSet executeQuery(String sql) {
rs = null;
try {
conn = DriverManager.getConnection(sConnStr,"hc_f","hcdingfaf");
Statement stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
}
catch(SQLException ex) {
System.err.println("aq.executeQuery: " + ex.getMessage());
}
return rs;
}
}
不知道是哪里错了，在服务器上调试时出现如下错误：
Note: sun.tools.javac.Main has been deprecated.
error: Can't write: /www/users/hc-edu.com/WEB-INF/classes/test/chatreg.class

请问哪位能够指点一下,在下将感激不尽！

在什么OS的服务器上调试的？用的什么方式编译？jdk什么版本？
