Question

I have a small Java method that inserts short messages to a MySQL Database.
the table’s default Collation is utf8_unicode_ci and the java code is:

private void insertMessageToDataBase(String lRoom, String lChatusername,
            String lMessage) {
        try {
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost/embeddedChat?" +
                "user=site_access&password=XXXXXXX");
            addMessageToDataBase = con.prepareStatement("INSERT INTO `" + lRoom + "` (username, message, action)" +
                    " VALUES (?,?,'message');");
            addMessageToDataBase.setString(1, lChatusername);
            addMessageToDataBase.setString(2, lMessage);
            addMessageToDataBase.executeUpdate();
        }
        catch (SQLException e) {
            e.printStackTrace();
        }
    }

the problem is that when lMessage is in hebrew the result is a string of ‘??????’

BTW:
I don’t know if it helps but there is also a PHP script that sometimes write to another similar table in this database and it works fine.

Set UTF-8 in your code. See this;

    Connection con = DriverManager.getConnection("jdbc:mysql://localhost/embeddedChat?useUnicode=true&characterEncoding=utf8");
