try{String temp_p=str;
byte[] temp_t=temp_p.getBytes("ISO8859-1");
String temp=new String(temp_t);
return temp;
}
catch(Exception e){ }
return “NULL”;
}
%> <%
request.setCharacterEncoding("gbk");
Connection con=null;
String username=request.getParameter("username");
username=getStr(username);
String email=request.getParameter("email");
email=getStr(email);
String doc=request.getParameter("doc");
doc=getStr(doc);
try {
Class.forName("com.mysql.jdbc.Driver");
Connection connection=DriverManager.getConnection(
"jdbc:mysql://localhost:3306/notepad,"root","1234";); String str="insert into notepadtable(username,email,doc) values(?,?,?);";
PreparedStatement pstmt=con.prepareStatement(str);
pstmt.setString(1,username);
pstmt.setString(2,email);
