Problem to insert Chinese Characters(GB3212) into MySQL

I met a problem to insert Chinese Characters (GB3212) into MySQL using Entity Bean (or JPA).
For example, when a hardcoded string "{color:#ff0000}电器me元件{color}" is inserted, it is displayed as "{color:#ff0000}??me??{color}" in MySQL.
The NamedQuery is also not working for Chinese Characters.
The setting are as following:
GlassFish JDBC connection pool: useUnicode=true, charecterEncoding=gb2312
NetBeans IDE: source encoding set to GB2312;
MySql table: the column set to CHARACTER SET gb2312;
Any experts, please give advice
Thanks lot

I didn't noticed that there is a {color:#ff0000}sun-resources.xml{color} file under {color:#ff0000}<ejb project>/server resources{color}.
This file has a pool configuration. This config just overwite the paremeter i added using Admin Console every time a client is lauched. So there are two option to fix this problem.
1. Insert the follwowing two lines into the {color:#ff0000}sun-resources.xml{color}
<property name="characterEncoding" value="gb2312"/>
<property name="useUnicode" value="true"/>
2. delete the everthing in the {color:#ff0000}sun-resources.xml, using Admin Console {color}config your own pool & DataSource
I tried first option & it works.

Hi, Jenny,
When you said unable to insert to database, do you mean you get all ? marks in the database or garbage characters in the database?
? marks mean there are some byte chop off, and garbage characters mean the bytes are ok, just encoding problem.

Insert chinese characters to mysql

I have searched the forum and found a useful links --http://forum.java.sun.com/thread.jspa?threadID=530358 about inserting chinese characters to mysql. However, I can't see the chinese characters displayed in the db. The charset and collation of my table are utf8 and utf8_bin respectively. Can anyone help me? Below is my source code

Besides, if I code the chinese characters directly in the servlet page, what is the encoding of the chinese characters by default? Is it related to my OS locale?
Thanks a lot.

objConn.execQuery(conn, "insert into TBL_test
st (test_desc) values ('" + sValue.getBytes("UTF-8")
+ "')");You would be better off using a PreparedStatement and parameters. This will let the MySQL JDBC driver take care of the required encoding.

Problems in displaying chinese characters with utf-8 encoding

Hi,
I got problem in displaying chinese characters in my web application.
I am creating a web application supporting both English and Chinese charaters. What I am trying to do is:
1. storing some chinese characters via a web page (page1) into database.
2. retrieve the chinese characters via another web page (page2) from the database.
Once I put the Chinese characters on the webpage (page1 in step #1), it displayes well (the readable chinese characters) before I submit this page (after submit, the data will be stored into the database).
But when I tried to display the chiese characters via page2 in step#2, I got un-readable characters displayed.
The running configuration is: Sun Application Server (coming and with the JSC2) and MySQL server 5.0. And I setup the database server with utf8 as character-set.
It seems like the chinese characters got messed up throught the round-trip (from page1<----via jdbc---->database<----via jdbc------>page2).
From the database, I found the chinese characters are there. Any helps are appreciated.

Hi,
I am trying to insert new record.The record may contain chineese or English data.
I did same what u specified.
first I converted to the byte UTF8.again,I converted byte to string using 8859_1.
the values are not storing chinese characters.
pls suggest me.
below is my code.
                              ascCode = req.getParameter("asccode");

How to insert chinese characters in a table use FDK?

Hello~~
I am expecting to insert chinese characters in an XML file's table.
I'm using FDK7.2, if i use:
F_ApiAddText(docId, &tRange.beg, "asdf");
The English letters "asdf" can be insert correctly in the right place,
But, if insert chinese characters like this:
F_ApiAddText(docId, &tRange.beg, "人们");
No characters insert.
How can i solve this problem?
Please advise
Thanks
zhaopeng

Zhaopeng,
Which encoding are you using for the Chinese characters? FrameMaker 7.2 does not support Unicode or UTF-8. I have not done this before, but I guess you need to supply the characters in Big5 resp. GBK encoding, see
http://help.adobe.com/en_US/FrameMaker/8.0/chinese_korean.pdf
[Ignore the 8.0 in the URL, the document talks about FrameMaker 7]
You also may have to make sure the paragraph format at your text location uses a Chinese font before inserting characters.

How to Insert Chinese characters in Japanese Database

Hi all,
I am having following characteristics on my computer
Machine OS --Windows Server 2003
OS language --Japanese

NLS_LANGUAGE JAPANESE
NLS_CHARACTERSET JA16SJIS
Now, i want to insert into database chinese characters. Please guide me how to do the following thing.
How to insert chinese characters on local machine and if i want to insert on the remote databse (i can not create database link for remote database). I have to send batch file or SQL file and they will execute it on their side.
if i use this command
alter session set nls_language = "SIMPLIFIED CHINESE"
and then insert the records and revert back to japanese character set. Is this correct way....?
Thanks in advance,
Pal

As dombrooks has pointed out, unless all the Chinese characters you are trying to store can be represented in the Shift-JIS character set, which seems unlikely, but I'm not an expert on East Asian languages and I believe there are some glyphs that are shared between various languages, then you're not going to be able to store this data in this database in CHAR or VARCHAR2 columns.
Depending on the national character set, you may be able to store the data in NCHAR/ NVARCHAR2 columns, though using these data types can substantially increase application complexities since various languages and libraries don't support NCHAR/ NVARCHAR2 columns or require you to jump through some hoops to use them. Your applications would also have to support both character sets, so your applications would all have to be Unicode enabled most likely, which is certainly possible but it may not be a trivial change.

Unable to insert Chinese characters in Database

My problem is that I am not able to insert chinese
(to traditional chinese) characters into my tables in the
database.
I have changed the character set to UTF8 while creating the
database and also tried the alter session command in SQL to
alter the NLS_LANGUAGE and NLS_TERRITORY (to say traditional chinese).
But this did not solve my problem.
Also tried all possibilites like getting Chinese characters
in my notepad by copy - paste from a Chinese web site
but while giving the insert into command in my database
it takes some junk values.
Someone PLEASE HELP!!!URGENT!!!
Thanks in advance.

You mentioned in your first note that you have set your database character set to UTF-8? If so, then you are able to store and retrieve multilingual data, including Chinese and Japanese characters. Your issue is not the database. Your client OS must be able to support these languages as well. It is likely that your version of OS supports only Latin and Western European characters. By the way changing your NT regional setting only effects sorting, date formats etc. It doesn't help you change the languages that your keyboard will support.
1.To determine your Win32 operating system's current ANSI CodePage (ACP). This can be found by bringing up the registry editor (Start --> Run..., type "regedit.exe", and click "OK") and looking at the
registry entry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\CodePage\ACP (there are many registry entries with very similar names, so please make sure that you are looking at the right place in the registry).
2.To find the character set in the table below based on the ACP you got above.

(*1) The character sets listed here are compatible with Win32's non-Unicode graphical user interface (GUI). Since Win32's MSDOS Box (Command Prompt) uses different character sets, NLS_LANG needs to be manually set in the MSDOS Box (or set in a batch script) in order to handle the difference
between Win32's GUI and MSDOS Box. (Please see "NLS_LANG Settings in MS-DOS Mode and Batch Mode" in the Oracle8i Installation Guide Release 2 (8.1.6) for Windows NT, part# A73010-01.)
(*2) If you use UTF8 for the 3rd part of NLS_LANG on Win32, client programs that you can use on this operating system would be limited to the ones that explicitly support this configuration. Recent versions of Oracle Forms' Client/Server mode (Fat-Client) on NT4.0 would be an example of such client
programs. This is because the user interface of Win32 is not UTF8, therefore the client programs have to perform explicit conversions between UTF8 (used in Oracle side) and UTF16 (used in Win32 side).

INSERTing chinese characters in SQL*plus

Db version: 10gR2
NLS_NCHAR_CHARACTERSET for my DB is AL16UTF16 by which i can store chinese characters. To INSERT using SQL*Plus, i tried to copy and paste some chinese characters from internet. When the characters get pasted, it becomes '?????' (question marks). What else do i have to set to store Chinese characters?

Inserting chinese characters

hi
I have my Database with UTF-8 characterset.
I have sql file that contains data in chinese characters.
I need to run this sql and insert data into my database tables.
The sql file is simple text file saved in UTF-8 encoding.
Do I need to install chinese font on my machine to be able to run the sql successfully?
My nls_lang setting is AMERICAN_AMERICA.UTF8.

What is your operating system characterset? What is your database's operating system? What version of Oracle do you use?

Do I need to do any changes to anything ??
Thank you in advance.

How to insert a bean variable into MySql using jsp

Hi, I have a problem that I have been trying to work out for ages..unsuccessfully.
My web-site takes 2 inputs off a user...does a calculation on them and returns the result to the user.
I want to then use another jsp page that will take this result and insert it into a database...
My class code for this is :
public void updateRepmax(String userName, String repmax) throws SQLException, Exception{
     if(con != null){
     try{
     PreparedStatement update;
     update = con.prepareStatement("UPDATE repmax SET Benchpress = ?, WHERE Member_Name = ?");
     update.setString(1, repmax);
     update.setString(2, userName);
     update.execute();
     } catch(SQLException sqle){
     error = "SQLException: could not update repmax";
     throw new SQLException(error);
     catch(Exception e){
     error = "An exception occured while updating repmax";
     throw new Exception(error);
     } else {
     error = "Exception: connection to database was lost";
     throw new Exception(error);
My JSP is :
<%@page import="java.sql.*, placement.*"%>
<jsp:useBean id="conn" class="placement.DBConnect" />
<jsp:useBean id="query" class="placement.DBQuery" />
<jsp:useBean id="bpcalc" class="placement.repmaxBean" />
<jsp:useBean id="userin" class="placement.User" />
<html>
<head><title>Update Repmax</title></head>
<body>
<%
conn.connect();
     String repmax = bpcalc.getRepmax();
     String userName = userin.getUserName();
query.setCon(conn.getCon());
     query.updateRepmax();
conn.disconnect();
%>
     </body>
     </html>
The variable I am tryin to insert is repmax ,in the class that does the calculation the repmax is a double so I assume that is my first problem(how can this be changed to allow it to insert?)....any help you have to offer would be greatly appreciated...

Thanks for your reply sathishkb,
I am not actually receiving any error message,
The jsp page is processed and the code seems to be correct however the table in my mysql database is not updated.. my JDBC drivers are working correctly etc.
I expect that the problem is in my JSP page but dont know what it is
I have removed that comma in my update statement
I no longer have the problem of the variable being of type touble as I altered my other code to convert the variable from double to string
jsp is now:
<%@page contentType="text/html"%>
<%@page import="java.sql.*, placement.*"%>
<jsp:useBean id="conn" class="placement.DBConnect" />
<jsp:useBean id="update" class="placement.DBQuery" />
<jsp:useBean id="bpcalc" class="placement.repmaxBean" />
<jsp:useBean id="currentuser" class="placement.currentuserBean" />
<html>
<head><title>Insert Into Repmax</title></head>
<body>
<%
String repmax = bpcalc.repmax;
String userName =currentuser.name;
conn.connect();
     update.setCon(conn.getCon());
     update.updateRepmax(repmax,Username);
conn.disconnect();
%>
     </body>
     </html>
the segment of my bean code is :
public void updateRepmax(String repmax,String userName) throws SQLException, Exception{
     if(con != null){
     try{
     PreparedStatement update;
     update = con.prepareStatement("UPDATE repmax set Benchpress = ? WHERE Member_Name= ?");
     update.setString(1,repmax);
     update.setString(2,userName);
     update.execute();
     } catch(SQLException sqle){
     error = "SQLException: could not update employer";
     throw new SQLException(error);
     catch(Exception e){
     error = "An exception occured while updating employer";
     throw new Exception(error);
     } else {
     error = "Exception: connection to database was lost";
     throw new Exception(error);

Encoding or font problem? Simplified Chinese characters

Would be great if someone could help!
I don't know much about Dreamweaver but trying to use it to create an invitation in Chinese. I tried to edit a template I used for an English invitation. But when I preview it in IE, some characters become weird but some are fine. I tried to use different fonts to test, and set different encoding from Edit > Preference. But nothing really changes. I have attached the file in IE. Anyone knows what's wrong?
Thanks a ton!

The only help I can offer is a post made by David Powers to a similar question some time ago:
Change the page encoding. Modify > Page properties > Encoding. Depending
on the type of Chinese, choose Chinese Traditional (normally used in

I have a requirement that when ever user enters the value in Billing Qty input which is in VF01 tcode and the table is VBRP-FKIMG, and client want billing qty and previous month reading, the fields are not in VBRP. So I have created a custom table name as YSD-EXPORT_QTY with fields of CUSTOMER, MONTH, YEAR, BILL_QTY, PREV_READING, CUMULATIVE... When ever user enter the Billing Qty I want to update database table and initally there is no data in custom table. I tried below code but i am not getting and i am getting the error as
"The type of the database table and work area (or internal table) "WA_EXPORT" are not Unicode convertible. "
So, How can I resolve this issue.. I am trying this since from 3 days... if u have any sample code please give me...
MOVE WA_VBRP-FKIMG TO WA_EXPORT-BILL_QTY.
WA_EXPORT-CUMULATIVE = WA_EXPORT-BILL_QTY + WA_EXPORT-PREV_READING.
WA_EXPORT-PREV_READING = WA_EXPORT-CUMULATIVE.
APPEND WA_EXPORT TO IT_EXPORT.
INSERT INTO YSD_EXPORT_QTY VALUES WA_EXPORT.

If it overrides existting record, you should add new key fields to your database table, there can be only one record per set of key values.
I suppose keys look like MANDT, KUNNR, GJAHR, MONAT or MANDT VBELN POSNR or a combination of both set of keys (not sure to understand you requirement)
You have to first read from database if some data already exists,
- if yes, add the new quantities and UPDATE the record
- if no, INSERT a new record
Remember keys define a unique record, and cannot be updated once inserted.
If your program should never update records, add a "technical" key field, and fill it using a timestamp or a number range counter (FM NUMBER_GET_NEXT)

Problem in printing Chinese characters by using JavaPrintService

Hi, I just develop a tool to print txt files by using Java Print Service.
Everything seems to be good, but when the file contains Chinese character, it can't be print correctly.
I tried to use the DocFlavor.Reader and DocFlavor.STRING, however all of them are failed.
My code is below, please help me, thanks so much
PrintRequestAttributeSet pars = new HashPrintRequestAttributeSet();
// TODO:Printing is not correct because of the Chinese Encoding
DocFlavor flavor = new DocFlavor.INPUT_STREAM("text/plain;charset=UTF-8");//DocFlavor.INPUT_STREAM.AUTOSENSE;
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
if(defaultService != null){
Iterator<String> it = filename.iterator();
while(it.hasNext()){
shortname = it.next().toString();
abstractPath = GlobalVar.SRC_DIRECTORY_PATH + shortname;
File file = new File(abstractPath);
if(file.exists()){
try{
DocPrintJob job = defaultService.createPrintJob();
FileInputStream fis = new FileInputStream(file);
//BufferedReader br = new BufferedReader(new InputStreamReader(fis,"UTF-8"));
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(fis,flavor,das);
job.print(doc, pars);
}catch(PrintException ex){
Log.doLog("Print failed\t" + shortname, Log.ERROR);
System.out.println(ex.fillInStackTrace());
}else{
Log.doLog("File can't be found: "+abstractPath, Log.ERROR);
}else{
Log.doLog("Can't find printer", Log.ERROR);
}

Everything seems to be good, but when the file contains Chinese character, it can't be print correctly.And how exactly did you determine that the character set in that file is UTF8?
