Problem with java, ASCII and Linux

Hi Friends,
I has a Linux RedHat 9.0 with a jre1.5.0_04 (rpm package of Sun).
I has a problem with ASCII , for example :
import java.io.*;
public class HolaMundo
public static void main (String[] args)
System.out.println("Hol� M�ndo");
this programs runs ok on my windows jdk so it prints "Hol� M�ndo", but when i run the same HolaMundo.class program on my linux redhat it prints "Hol�� M��ndo"
I think the problem is with the ASCII table that uses the linux version of jre, but i dont know how to solve this problem. I need a Spanish-European ASCII table on my application but i think it is working with a US-ASCII table.
Then i has installed a kaffe 1.0 (rpm) java machie on this linux and this solve the problem but i has another problems of compatibility with this old version of java kaffe.
Do you know whats happening?
Thanks in advance.

The problem doesn't have to do anything with Java or Linux as far as i can see. It's more likely a problem with Windows XP and IE. Be assured that normally downloading the Linux JDK in windows is not a problem.

Problem with java installation on Linux

HI ,
I am trying to install jdk on Linux..I am new to java and Linux both. I am trying to download the file for the linux installation onto my home PC(windows XP) and then ftp it to my Linux machine. I need to do this because I have a remote login to my Linux machine( a server at school). However when I try to download file my IE jsut crashes. I can see the page for accepting the Agreement but when I click on Accept the next page just stops responding.
Could someone explain why this is happening.
thanks,
G.

Problem with Java 5 and Oracle 10g JDBC driver

Hi All,
Currently we upgrade our web application to Java 5 and Oracle 10.2 JDBC driver. And we encountered a bug, when the user entered the information through UI and data didn't store into database (Oracle 9i). The problem is that this bug is not happend so often maybe once a day and this did not happen before we upgraded to Java 5 and Oracle 10.2 JDBC driver. Does anyone encounter the same problem ? Is this Java 5 problem or Oracle JDBC driver problem ?
Thanks,

sounds like a database problem...
Are you using a driver version that's supported for your database engine?
What else did you change? We once ran into a major bug in our application that had for 5 years been masked by performance problems in our hardware and infrastructure.
Once those were resolved the bug showed itself and caused tens of thousands of records to be erroneously inserted into our database every day.
It's certainly NOT a problem with your JVM (if it's a decent one, like the Sun implementation).
So it's either your database, your driver, your network (dropping packets???), or your application.
The upgrade may just have exposed something that was already there.

Problem with Java Dates and UPDATE for SQL2000

I am having problems with the date formats for Java. I am trying to put the current date time into a SQL table, here it the code I am using:
var Today = new Date()
var conn = Server.CreateObject( "ADODB.Connection" )
conn.Open( "Provider=SQLOLEDB;Server=(local);Database=BillTracking;UID=sa;PWD=;")
var sql = "UPDATE BillAssignments SET DatePosted = " + Today + " WHERE AssignmentID = '" + Request.QueryString("AssignmentID") + "'"
var rs = conn.execute(sql)
I keep getting different errors and I have been unable to find a solution yet. I know that I need to change the date format from the Java standard to the one that SQL likes.
Help....
Norm...

Please tell us where the Java part of this comes in. I see that you are using JavaScript to load up data via an ADO connection (presumably on an IIS platform) - but I do not see where you are using Java

          You realy can do it like Xiang says, but the better way is to use packages. That's
          the way BEA is designed for. If you use packages you can but your bean classes
          in every subfolder beneath Classes. Here for example we have the subfolders test
          and beans:
          You have to declare the package on top of your Bean Source Code:
          package test.beans;
          In your JSP you don't need the import code of Xiang. You only have to refer the
          path of your bean class:
          <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
          There are some other AppServers that only can deploy Java Beans in packages. So
          if you use packages you are always on the right side.

Problem with java look and feel

Hi! This is my first time posting here. Do apologize me if I am not familiar with the regulations here. Thanks!
Currently, I am developing a project using NetBeans IDE. It is using RMI, and some basic UI. I am facing the following error when I tried applying the java look and feel code. Please see below for the code used and the error message.

Problem with Java keystore and certificates (unable to find valid cert path

Our program is made so that when a certificate is not signed by a trusted Certification Authority, it will ask the user if he/her wishes to trust the certificate or not. If they decide to trust the certificate, it will accept the self signed certificate and import it into the keystore and then use that certificate to log the user in. This works fine. It will import the certificate into the keystore and use the specified ip address to establish a connection with the LDAP server (Active Directory in our case) and authenticate properly. However, the problem arises when we then try and connect to a different ip address (without restarting tomcat, if we restart tomcat, it works fine...). It imports the certificate into the keystore fine, but always gives the exception
"Root exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
and does not authenticate with our LDAP server (which is Active Directory). The problem seems to be that it is no longer looking at the System.setProperty("javax.net.ssl.trustStore", myTrustStore);
I have tried multiple times to just reset this property and try and "force" it to read from my specified trust file when this error happens. I have also imported the certificates directly into the <java_home>/jre/lib/security/cacerts and <java_home>/jre/lib/security/jssecacerts directories as the java documentation says that it will look at those directories first to see if it can find a trusted certificate. However, this does not work either. The only way that I can get this to work is by restarting tomcat all together.
If both of the certificates are already in the keystore before tomcat is started up, everything will work perfect. Again, the only problem is after first connecting to an IP address using TLS and importing the certificate, and then trying to connect to another IP address with a different certificate and import it into the keystore.
One of the interesting features of this is that after the second IP address has failed, I can change the IP address back to the first one that authenticated successfully and authenticate successfully again (ie
I use ip 1.1.1.1, import self signed certificate, authenticates successfully
login with ip 2.2.2.2 import self signed certificate, FAILS
login again with 1.1.1.1 (doesn't import certificate because it is already in keystore) successfully authenticates
Also, I am using java 1.5.0_03.
Any help is greatly appreciated as I've been trying to figure this out for over a week now.
Thanks

When imported to Forms, i have the package with this clasess...
The problem is when i have to call a SetIva Method.
In pl/sql i have
Case 1
OraAlicIva := AlicIva.new(); --OK
AlicIva.setBase(OraAlicIva , 10); --OK
Class1.setIva(Object_to_Class1, OraAlicIva); --Error, is not type excpected
Case 2
OraAlicIva := ArrayOfAlicIva.new(); --OK
AlicIva.setBase(OraAlicIva , 10); --Error, setBase is not defined
Class1.setIva(Object_to_Class1, OraAlicIva); --OK
Case 3
OraAlicIva := AlicIva.new(); --OK
OraAlicIva2 :=ORA_JAVA.NEW_OBJECT_ARRAY(1,'ArrayOfAlicIva'); --OK
AlicIva.setBase(OraAlicIva , 10); --OK
ORA_JAVA.SET_OBJECT_ARRAY_ELEMENT(OraAlicIva2 , 0, OraAlicIva); --Error, ExceptionStoreArray
Class1.setIva(Object_to_Class1, OraAlicIva); --OK
The Solutions in Java is
AlicIva[] alicIva = new AlicIva[1];
alicIva[0]= new AlicIva();
alicIva[0].setId(Short.parseShort(1));
fedr[0].setIva(alicIva);}
Is posible to Resolve ??
Thanks and Sorry for my inglish

Thanks for the answer but the problem is the type of object of method and how from pl/sql is posiblle to call.
The method waiting a ArrayofAlicIva, but if i define this object is not posible to set the object inside the array because the wsdl not have this functions.
I need to define array of objects but the object is inside is the diferent type of array.
If i Define the array of object correct to object inside, the method expect that the other array type.
Is a Deadlock ??
The solution in Java is Simple
AlicIva[] alicIva = new AlicIva[1];
alicIva[0]= new AlicIva();
alicIva[0].setId(Short.parseShort(1));
fedr[0].setIva(alicIva);
this is the method imported in java class to form
-- Method: setIva (LArrayOfAlicIva;)V
PROCEDURE setIva(
obj ORA_JAVA.JOBJECT,
a0 ORA_JAVA.JOBJECT) IS
BEGIN
args := JNI.CREATE_ARG_LIST(1);
JNI.ADD_OBJECT_ARG(args, a0, 'ArrayOfAlicIva');
JNI.CALL_VOID_METHOD(FALSE, obj, 'FECAEDetRequest', 'setIva', '(LArrayOfAlicIva;)V', args);
END;

Problem with Java Proxy and Socket Connection

Hi Gurus!!
I have developed a Java Proxy that connects via socket with a Server Socket application. This Server Socket application accepts more than one connection at the same time.
When I connect the first time from my Java Proxy, the connection is correctly established. When the first connection opened, if a try a second connection, this is not established.
I use "new Socket(SocketServer,SocketPort);" to open the connection.
I think that all time the Java Proxy is trying to open the same connection, and this is a problem.
Is there a way to indicate to the server that is a new connection and that the existing connections remain?
Anybody could help me, please?
Thanks and regards,
Manuel Míguez.

Problems with non-ASCII characters on Linux Unit Test Import

I found a problem with non-ASCII characters in the Unit Test Import for Linux. This problem does not appear in the Unit Test Import for Windows.
I have attached a Unit Test export called PROC1.XML It tests a procedure that is included in another attachment called PROC1.txt. The unit test includes 2 implementations. Both implementations pass non-ASCII characters to the procedure and return them unchanged.
In Linux, the unit test import will change the non-ASCII characters in the XML file to xFFFD. If I copy/paste the the non-ASCII characters into the Unit Test after the import, they will be stored and executed correctly.

Problem with Java and Windows (Mainly Vista and UAC)

Hi all,
I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
During the process I have noticed that there are several key problem with java for this type of application!
The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
<code>
cd PATH TO PROGRAM
start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
pause;
</code>
Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
Has anyone else had this probem and has a suitable solution?
Any advice on these issues would realy be appricated.
Regards
Joey

Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
A link to the site I got it was
http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
This program allows you start java with a UAC dialog for high access using
Elevate java -jar myjar.jar
This then allows you to have full access using java... I guess it could be dangerous but it does the job.

Problem with java swing button and loop

Problem with java swing button and loop
I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
When I click on start button it must do next:
Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
And when I click on stop button it must do next:
Start button must set enabled and selected and Stop button must set disenabled.
Field status is set to 0.
This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
There is java code, so you can get better picture:
/** start button */
public void gStart_ActionEvents() {
try {
ivjGStart.setEnabled(false);
ivjGStop.setEnabled(true);
ivjGStop.setSelected(true);
getJTextPane1().setText("Program is running ...");
Status = 1;
} catch (Exception e) {}
/** stop button */
public void gStop_ActionEvents() {
try {
ivjGStart.setEnabled(true);
ivjGStart.setSelected(true);
ivjGStop.setEnabled(false);
getJTextPane1().setText("Program is NOT running ...");
Status = 0;
} catch (Exception e) {
/** procedure IzvajajNeprekinjeno() */
public void IzvajajNeprekinjeno() { //RunLoop
try {
int zamik = 2000; //delay
do {
Thread.sleep(zamik);
PreberiDat(); //procedure
} while (Status == 1);
} catch (Exception e) {
So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
Any help will be appreciated.
Best regards,
Tomi

This is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
Since java is task-based this will happen if you do like this:
1. Button "Start" is pressed. Thread running: GUI_Thread
2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
5. Call PreberiDat(). Thread running: GUI_Thread
6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.

I have a problem with Java and an e-procurement system integrating

I use an e-procurement system at work and yesterday I could not get my parts list from the suppliers web site to display in our in-house eprocurment finance package.
There is not a problem with the finance package. There is not a problem with the suppliers web site. I have verified both of these by other colleagues being able to complete what I am trying to do.
The difference between my version of Firefox and my colleagues' is that I am on version 6.0.1 and they are on 6.0.
I have had problems with Java not displaying certain animations on the suppliers web site but, my colleague does not and I am suspicious that this is the problem. Can anyone verify this please and what can I do about it. My Java updates are up-to-date as of yesterday and are automatic.
Thanks.

I was quite amazed I never got a reply to this, in the past people here have been helpful. In any case I was finally able to enter this website on the exceptions list in the Java panel, and I believe it is okay now.
