Question

I have three textfields (ID,Name,Address) which reflects columns in DB table i’m trying to insert arabic characters into that table but it appears as “?????”

iam connecting to DB using JDBC
my Database info. : MySQL Server 5.5.14 community
Server characterset: latin1
Db characterset: utf8
Client characterset: latin1
Conn. characterset: latin1

i try to encode strings using the following code:

private String ArEncode(String text){
    String txt="";

    try {

        Charset cset = Charset.forName("utf8");
        CharsetEncoder encoder = cset.newEncoder();
        CharsetDecoder decoder = cset.newDecoder();
        ByteBuffer buffer = encoder.encode(CharBuffer.wrap(text));
        txt=buffer.asCharBuffer().toString();        

    } catch (Exception ex) {
        Logger.getLogger(UserView.class.getName()).log(Level.SEVERE, null, ex);
    }
    return txt;
}

then the returned string “txt” is inserted in to the database

note: when i try to insert values directly into DB from netbeans it is inserted correctly and the Arabic characters appears correctly.

Why would you do this? It’s the job of the mysql JDBC driver to encode strings correctly in the declared database character set. Set your character set in the database to UTF-8, set the JDBC options correctly, and just do a plain insert of a plain old String.
