JAVA + MYSQL + ACCESS + ENCODING!!! help needed here!!!!

i have to migrate some data from access to mysql. however, i have some japanese characters in the access table and whenever i am done w/ migration and open the mysql table, i see bunch of ?????? instead japanese character. since im now working for a japanese company, this pc is in japanese eviorioment.
i set mysql table to use utf8. does anyone here know whats going wrong? i guess there is something to do w/ encoding stuff. please help!!!
here is some more information:
java1.5.1, access2003, mysql5.1 and japanese xp

This is the third thread you have opened on the same problem within the last couple of days, and you have not provided any more information than in the first one that would let people figure out what you are doing and thus help you.
In the first thread you opened it seems you had gotten to the point of realizing that you couldn't insert Japanese characters correctly in your mysql database, right? So it seems that the problem is simply with your mysql configuration and/or the way you interact with it from Java.
So, to narrow the problem down further:
1. Can you insert Japanese directly into mysql (not from Java) and get them rendered correctly? That would indicate your DB is configured correctly.
2. What is the code you use to insert Japanese characters into mysql? (start with hardcoded Japanese, don't mix the Access migration into this yet)

Multiple ethernet network adaptors + MySQL/php5: configuration help needed

I would be grateful if someone could give me some advice on how to configure multiple ethernet adapters under OS X 10.5.6
I have set up my system to work nicely with two ethernet network adapters, each with its own fixed IP. This bit works just fine. The machine supports two separate servers - a mail server and the OS X Apache2 server. I have configured the mail server to only listen to one of the IPs, and the Apache2 server to listen to the other (via httpd.conf). The system also has MySQL and php5 installed / enabled, and these services are only used by the Apache2 server.
The problem I have is that when I start the machine, initially the php5 system cannot connect reliably to the MySQL database system. The fix I have found is to temporarily make the ethernet adapter connected to the mail server 'inactive'. While this is so, the php5/MySQL connection to Apache2 works. Curiously, once an initial connection between php5 and MySQL has been made, subsequently I can make the mail server's ethernet adapter active again without further problems.
I initially thought this might be due to 'service order' issues - but changing the service order (e.g. putting the Apache adapter 'above' the mail adapter in the service order does not help. The fix only works by making the mail adapter inactive temporarily.
I suspect that there is some configuration change I can make to clarify the setup I have. The MySQL and Apache installations only need to talk to the Apache server - but I am not sure how to record this configuration in the OS X system.
Thanks in advance for any assistance that you can provide.

I need to learn how to use all about java & mysql...help me!

I have a situation here, I need to learn how to use java with mysql
. Can I connect to a MYSQL DB with servlets?
how can I build an e-mail server with java (no matter how difficult)
please, I need help, and I really apreciate your help.
thank you very much!!

I have a situation here, I need to learn how to use
java with mysql
. Can I connect to a MYSQL DB with servlets?Yes... documentation to help you connect to any database can be found at http://java.sun.com/products/jdbc. To connect to MySQL, you'll need drivers (sourceforge.net), and the specific connection URL for those drivers will be included in the documentation.
how can I build an e-mail server with java (no matter
how difficult)If you're fairly new to JSP/Servlets, you may be in over your head here, since an email server is no easy application to code. Here's a link to the source code for the JAMES project... Apache's Java email server... maybe you can find some useful information there...

"com.mysql.jdbc.PacketTooBigException": Help needed urgently

hi,
I am using mm.mysql j/connector ver 3.0.6 and MYSQL server version 4.0.
Max_allowed packet= 8MB at the server side
I am getting PacketTooBigException when i am trying to update a particular column.
What should i do.
Any help will be greatly appreciated!!!

the driver uses a 64 k max packet size by default. it is supposed to change this as neccessary upon connection but perhaps that is failing?
below is the 3.0.7 connection code that i have slightly modified for you so that it prints out the connection properties after they have been initialized so that you can see what they are.
try it out and i hope you find this helpful.

Java Wireless Toolkit Setup Help Needed

I am interseted in mobile application development, and I have recently tried to set up the Java Wireless toolkit 2.0 on my laptop.
I have spent gours trying to get it to work correctly - still nothing!!
When it's all installed, I have opened up the sample projects -- e.g. Games.
When I hit 'Build' I am given the following error:
Project "games" loaded
Project settings saved
Building "games"
C:\WTK20\apps\games\src\example\pushpuzzle\PushPuzzle.java:145: cannot access java.lang.StringBuilder
file java\lang\StringBuilder.class not found
alert.setString("Could not load level " +
^
com.sun.kvem.ktools.ExecutionException
Build failed
Can someone please tell me what to do?!?
Is it to do with setting the classpath?? How do I do that??
What other Java tools do I need to have prior to installing the Wireless toolkit?? JVM?? Where do I get this? How do I install it correctly and set paths correctly??
Any help would be HUGELY appreciated as I have downloaded so much stuff at this stage I have compleely confused myself!!

Hey.
Right, last night I downloaded the latest version of JDK - version 1.5.
I installed it successfully.
So in the folder C:\ Java there are two folders: Jdk-1.5_etc and JRE-1.5_etc.
Next I downloaded and installed the latest version of the wireless toolkit.
It saw that I had the JDK installed at th correct folder, and it installed at C:\WTK20 - said it installed correctly.
So, next I select create project - call it hello world.
Then I place the following code in the src folder of the helloWorld folder:
* Copyright 2000-2001 by Sun Microsystems, Inc.,
* 901 San Antonio Road, Palo Alto, California, 94303, U.S.A.

public class HelloWorld extends MIDlet implements CommandListener {
private Command exitCommand;
private TextBox tb;
public HelloWorld() {
exitCommand = new Command("Exit", Command.EXIT, 1);
tb = new TextBox("Hello MIDlet", "Hello, World!", 15, 0);
tb.addCommand(exitCommand);
tb.setCommandListener(this);
protected void startApp() {
Display.getDisplay(this).setCurrent(tb);
protected void pauseApp() {}
protected void destroyApp(boolean u) {}
public void commandAction(Command c, Displayable d) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
I hit build and it builds correctly - no errors - YAY!!.
I hit run, the phone emulator pops up. I hit launch and:
An error pops up on the screen of the phone.
The error below appears in the Wireless toolkit window:
Project "HelloWorld" loaded
Project settings saved

Build complete
Running with storage root DefaultColorPhone
Unable to create MIDlet HelloWorld
java.lang.ClassNotFoundException: HelloWorld

I'm using version 1.5 of JDK - what have I not done - why won't it run.
I keep getting Java.lang errors!!!!
AAAGGGHHHHH!!!!!!!!!!!!!!!

Java Card Gurus.. help needed!!! Could be a hidden bug with JavaCard Tools!

Hello,
I've run into a small problem, if u could help me out, Id be really grateful.
The problem lies in the WAY the tools are used(apdutool, jcwde etc). The project envisages the running of the tools from a RELATIVE point of view and not absolute. That is, (simplistically speaking),
The Host side is handled thus:
I AM NOTrunning jcwde as : jcwde -p 9025 jcwde.app
The mode is : c:\javacarddk\bin\jcwde.bat -p 9025 c:\temp\raj\jcwde.app
The Card side is handled thus :
The CAP file generation is : c:\javacarddk\bin\converter.bat -config c:\temp\raj\walletfile.opt
The SCR file generation is : c:\javacarddk\bin\scriptgen.bat -o wallet.scr com/sun/..../javacard/wallet.cap
However. the SERVER responds positively with the "T=0 listening on port 9025" message,
but as soon as the CLIENT is started, ie
c:\javacarddk\bin\apdutool c:\temp\raj\wallet.scr,
The following exception is thrown :(SERVER)
java.net.SocketException: Connection reset by peer: JVM_recv in socket input str
eam read
jcwde terminating on receipt of SimulationException. See previous messages for
cause.
and on the CLIENT :
com.sun.javacard.apdutool.ReaderWriterError: Card powered down. (0x15)
Please help, as the source codes of the JavaCard API are not available, so I am unable to determine if this
RELATIVE path access is the root of the problem.
Any help is appreceiated!!!!
Thanks
--Raj

cref is not the same as JCWDE.
JCWDE uses class files to emulate Java Card environment. It doesn't support package installation.
If you want to test a package using JCWDE you should a) add path to your class files to classpath that is used by JCWDE and b) specify in JCWDE configuration file AIDs for your applets.
JCWDE receives APDU commands and transfer them to your classes, everything is executed in usual java VM. You can even put debug output (System.out.println(...)) into your sources.
cref if a 'c reference implementation' of Java Card VM. It executes Java Card bytecodes and emulates real device. It supports package installation (scriptgen/apdutool) and works with converted packages.
If you want to test a package using cref you should compile sources, convert class files into cap file, create a script for package installation and use apdutool to install and 'run' package in cref.

Actionscript Help Needed Here!!

Swuut up
My Event Listener wont work once the thumb_mc has loaded the
jpg... with this line commented out
//thumb_mc.loadMovie("images/dj1.jpg"); it works !!...but then all
im looking at is an empty movieClip that acknowledges when its
being clicked! great but it would be even better if i could get the
same result with an image loaded into the movieClip..mmMM.
The Code is attatched. If someone can help me out id really
appreciate it.
thanx

While I'm not going to post the working code for you, I can certainly point you in the right direction.
Take a look at the class java.util.GregorianCalendar. It contains methods (some located in Calendar) to do manipulations with dates. You should be able to use the API to figure out how to create two GregorianCalendar objects... one with the current date, one with the due date. Once you've got those, there are plenty of methods to retrieve the day of the week, the date in the month, etc. which will guide you to calculating your answer.
Excluding the weekends is going to be the trickier part, but then again, that's why it's your homework assignment. Try to get some code punched out, and if you have problems, come back here and post an exact problem, and someone will help out.

Encoding help needed

Dear all,
I am having a doubt about encoding and I would appreciate help from or a comment from an expert. Encoding sometimes is tricky.
I have a method that generates a byte array from a text:
public byte[] getBytes() {
StringBuffer sb = new StringBuffer();
sb.append(some text);
byte[] textInBytes = sb.toString().getBytes();
Returning a byte array is a requirement.
Then another team gets this byte array and stores it in a file like:
public void doStore() {
File file = new File(a_name);
FileOutputStream outputStream = new FileOutputStream(file);
outputStream.write(getBytes());
outputStream.flush();
outputStream.close();
The thing now is that another team that is reading that file needs it to be generated in latin1 (ISO8859_1), not UTF8 as it looks like it is being generated now due to a new customer.
The team generating the file says I should pass them the bytes in latin1 and thats what I am doing:
public byte[] getBytes() {
StringBuffer sb = new StringBuffer();
sb.append(some text);
byte[] textInBytes = sb.toString().getBytes(ISO8859_1);
Till tomorrow we wont be able to test the whole thing coordinating the three teams but I feel it is not only me returning the byte array in latin1 but also the team generating the file should save it as latin1. I think the default saving is UTF8.
Maybe something like:
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file),"8859_1"));
out.write(getBytes);
out.close();
but unfortunately write method of BufferedWriter doesnt accept byte arrays.
What is your idea about it? Do you think the team generating also needs to do some changes in their code? What changes? All I can see now is after they generate their file, opening it with Ultra edit it detects it is UTF8.
Any ideas or help will be welcome.
Thanks,
Dani.

Returning a byte array is a requirement.Then you are responsible for generating the correct byte array. You are doing that by specifying the character set to String.getBytes().
I feel it is not only me returning the byte array in latin1Correct.
but also the team generating the file should save it as latin1.The team generating the file is saving it as the bytes you gave them. Nothing else.
but unfortunately write method of BufferedWriter doesnt accept byte arrays.That's because it accepts char arrays, because Writers are for chars and Streams are for bytes. You said byte arrays were a requirement so they have to use Streams, or possibly the Stream came first and the byte[] array is a consequence of that decision. You might be able to get the interface changed to char arrays but you would then just be moving the problem of who sets the charset from you to them.
>
Do you think the team generating also needs to do some changes in their code?No.
What changes?None.
All I can see now is after they generate their file, opening it with Ultra edit it detects it is UTF8.I don't know what 'Ultra edit' is or how it makes its decisions. As the team writing the file isn't writing a BOM marker, there is no basis for that decision. It is probably a guess.

Any ideas or help will be welcome.

BER TLV Encoding Help needed

Hi all,
I am workig with personalization of Java card cardlet, I am building a desktop application for loading, installing and personalization of the CAP file.
I need to build some personalisation data in BER TLV encoded as per ASN.1. So any one has code for encoding and deoding BER TLV objects in J2SE
please share it.....
Thanks and Regards,
Anish

Hi,
That standard outlines how BER-TLV's are used in ISO7816-4 commands that have commands/responses as BER encoded objects. That is the same as how EMV formats data in a TLV. ASN.1 is just another structured data stream like XML and each standard that uses it will be the same, the only differences are the encoding methods use e.g. PER, DER, BER, XER etc. ASN.1 notation and the encoding rules are defined in ITU-T recommendations X.680X.699.
If you want a more complete example you should look at the links in my previous post for the layman's guide. This covers BER encoding rules for all data types.
Cheers,
Shane

Help needed here.........

hi , i want to display a progress bar in the client in a jsp file, after i had submitted a file to server.... that progress bar should be displayed untill the server responds..........
plese provide some code if possible

The java code in a JSP page is interpreted on the server, before the page is loaded into the browser on the client. My suggestion is that what you wish to achieve can be accomplished with javascript/DHTML.
And in the future, please use descriptive subject headings. This helps others who can benefit from this thread.

Mysql connectionpropertiestransform issue - help needed

Hi,
I have implemented com.mysql.jdbc.ConnectionPropertiesTransform class.
In the jdbc connection url, I have added
propertiesTransform=com.mysql.jdbc.ConnectionPrope rtiesTransformImpl
attribute.
I made jar of this implementation class file and i have placed this jar file inside webapps/ (application)/WEB-INF/lib. mysql-connector-java-5.0.4-bin.jar file is present inside \tomcat\common\lib.
I am getting following exception.
Unable to create the properties transform instance 'com.mysql.jdbc.ConnectionPropertiesTransformImpl' due to underlying exception java.lang.ClassNotFoundException: com.mysql.jdbc.ConnectionPropertiesTransformImpl
If I place mysql-connector-java-5.0.4-bin.jar inside webapps/ (application)/WEB-INF/lib, its working fine.
Any idea? Is it classpath/class loader issue?
Thanks in advance

Thank you very much..
But I cannot move my connection properties implementation jar file to tomcat common lib.
Actually i am mapping application user to database user. Depending on user who logged into the application, i have to connect to the database with that user id and password.
We are using spring framework for authenticating user.
If i move connection properties implementation jar file to common lib, i am not able to retrieve Authenticaton details of user.
(SecurityContext of spring is becoming null if we are calling from outside application)
Is there any other alternative?

WAG160N - setting as Access Point; help needed

Hi all, I have a WAG160N router currently acting as my main router and a spare Technicolor TG58n. I want to use one of them as a router extension but 1) not sure if it matters which way round, and then 2) how to do it!..
Also, if it helps/ is relevant, I do have a Homeplug in the lounge, where I want to put the router extension (going into a Gigabite switch, out to the TV, Blu-Ray and Amp). Not sure if plugging the extension router into this is worth it?
Thanks for all your help guys....

Hi there, Dean. It may be best to let the Linksys router act as a second router. You may refer to this link, http://kb.linksys.com/Linksys/ukp.aspx?vw=1&docid=785463d9ecaf4cac84aed245b08d615f_3733.xml&pid=80&r...
Just use the LAN to WAN steps.
By the way, check if the Homeplug works directly behind the router. If it does, then it should work while connected to the Gigabit switch that's in turn wired to the Linksys router.
Hope that helps.
