PLz Help New To Java
Hey im brand new to java and i just downloaded and installed jdk-1_5_0_01-windows-i586-p now im tryin to set up the PATH permanently but i have no clue how to i went to the install notes and typed in C:\Program Files\Java\jdk1.5.0_<windows>\bin in the command.com but everytime i do it says access is denied. i have no clue how to set up the path permanently beside what i tried plz help!!!
You didn't which OS you are running, but it's fairly similar for all windows.
Start->settings->control panel->system->advanced->environment variables
Go to System variables, click on path, click edit button and add a semicolon and the path at the end. DO NOT REPLACE EVERYTHING THAT'S THERE NOW.
I don't have 1.5 installed on this computer, but I'm willing to bet the real path doesn't have '<windows>' in it. Use Windows Explorer to find out where java.exe actually exists on the hard disk and use that path

Plz help to install java plug-ins
hi everybody,
i am new to the world of java, i want to install java plug-ins in mozilla 1.7 on redhat linux 9.
how to do it, plz help, thanx in advance..If Java was installed prior to Mozilla, it should have automatically installed.
If not, or Mozilla was installed first, use these instructions from Mozilla:

Dear experts,
I have a java application in form of a running thread that periodically does an activity ie running a BAPI in
SAP.I like to schedule this application at evening time.
Problem is that incase somebody remotely login to this Windows server using RDP and leave an open RDP session,
two instance starts one on RDP and other on console.
Now to overcome this problem i devised a solution myself that incase application detects session is remote
then it should exit itself. This is mentioned in forum undergiven.
http://forums.sun.com/thread.jspa?threadID=5410674&messageID=10835701#10835701
My perception behind carrying out this development was that incase session starts in remote then
app will automatically close and finally letting running only in console.
Now what happens is that scheduled task doesnot start at all on console ,incase console as well as RDP are open.
Instead it starts only on RDP failing instantly.So in nutshell,task doesnot start at all.My app log say that
service tried to open in remote session and got closed.Plz help as i have no way out.
My second question is that if i schedule task using RDP on remote server,will it run on Remote,console or both
of them.
Regards,

My app also generates a .lock file and make sure that only one instance is running.Still problem remains unresolvedAnd combining your other thread with the word "also" from this post just exacerbates your "problem". Also, the "lock" file was not to prevent two simulteneous runs (that leads to very distasteful race condition), but rather to prevent two runs within a set period of time when combined with the ServerSocket approach to prevent simulteneous runs. -

But I couldn't complete it or make the connection to the database, I want to fill in the blanks and then add it to the data base.
My database name is doctrak and the table name is employee_info and below the design of the table :
emp_code char 10
emp_name char 30
emp_dept char 15
emp_title char 10
emp_doj datetime 8
emp_dob datetime 8
I've installed the apatchi tomcat 401 and make the java environment.
So plz can any one help me in that?
ThanksBut I don't know how to handel the code, I didn't
study JSP or Java. I'm trying to learn it by doing
this, so please can you write the code for me in jsp
and how to put it in html then , how to do the
connection to my database?Iam sorry to disappoint you, but no.
If you are new to java and jsp taking up such a task to learn it is not ideal, nor
viable. I would suggest you learn the basics of the language first, then the basics
of jsp, then some jdbc and finally graduate to the example in question. There are
excellent tutorials avbl for all on the net.
Maybe someone else would even post the code here, but suggest you dont
waste time waiting on it.
All the best.
Cheers,

PLZ help me out i'm very new and confused to java
Hi~
I'm very new to java and I just brought a phone (Nokia 6670). It's capable of J2ME, as it says in the instrusction book, but I'm not so sure which Java to download. (THERE ARE SO MANY). Please help me out, I'm not sure what to do, since I'm putting games in Java.you want to develop your own game or just want to have some games on your new device?
your phone has java runtime already, and that's all you need to run java games .. you can download them from several locations
if you want to develop your own game then download Sun's J2ME Wireless Toolkit; also have a look at Nokia Developer's Suite and emulator for your device... -

<snip>The subject of this forum is Oracle databases. How does your problem relate to that subject?
Two bits of advice:
1) Make sure you ask questions in a forum related to your problem.
2) If you want to be taken seriously as a professional, drop the MS IM Speak and use the language of the forum. In this forum it is English, which is successfully used by many people for whom English is far from their native language. -
How can I access my java class file in a .jar file ...PLz Help anyone!!
Hi Folks,
I am new in Java programming, have a .jar file that contains .java files that I want no access and use from another .java file. These files in the .jar file basically form a library thus have no main-method. However I can not declare an instance of the library (in the .jar file) and use it within my program.
Plz help ...I have tried all I know in vain.

How to use padding scheme FIPS81 in java plz help?
Plz refer the below code using this code I m trying to decrypt XLS file using pass phrase.
I m using the same pass phrase which was used @ the time of encryption.
But the problem I m facing is that the file was encrypted in DOT NET_ using padding scheme FIPS81 and there impelmentation of FIPS81 is not available in JAVA so that it gives exception at the time of decryption which is given below
Exception : javax.crypto.BadPaddingException: Given final block not properly padded
I urgently need the solution of this problem so somebody plz help me to find the solution of this problem.....Ur reply would be appriciated.....!!
The File is Encrypted using below mechanism
ALGORITHM : AES
MODE : ECB
PADDING SCHEME : FIPS81
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import javax.crypto.*;
import javax.crypto.spec.*;
public class DecryptTest {
public static void main(String[] s){
String passPhrase = "passphrase";
String encFileName = "encsample.xls";
String decFileName = "decsample.xls";
FileInputStream encFileIn = null;
FileOutputStream decFileOut = null;
File f = null;
byte[] message;
try {
f = new File(encFileName);
encFileIn = new FileInputStream(f);
decFileOut = new FileOutputStream(decFileName);
message = new byte[encFileIn.available()]; //Read the encrypted file in from disk
encFileIn.read(message);
SecretKeySpec spec = new SecretKeySpec(passwordToKey (passPhrase), "AES");
//decrypt it
Cipher c = Cipher.getInstance("AES/ECB/NoPadding");
c.init(Cipher.DECRYPT_MODE, spec);
System.out.println("Block Size is >-->" + c.getBlockSize());
String decryptedString = new String(c.doFinal(message));
System.out.println("Decrypted message: " + decryptedString);
//To write into another files
decFileOut.write(decryptedString.getBytes());
}catch (Exception e) {
System.out.println(e);
}finally {
try {
encFileIn.close();
decFileOut.close();
} catch (IOException ioe) {
}Is there any mechanism is available for FIPS81 or Is there any third party Provider available for it plz reply........????????I suggest you look in google http://www.google.co.uk/search?q=SWF+java

hello all,
i'm new to java. i need to know answers to these questions..
1. What is the purpose of CLASSPATH? How �classpath� is used by �java� and �javac�?
2. What is the purpose of finally block?
3. What is �Ant�?
4. Explain the difference between abstract class and interface. When to use an abstract class and when to use an interface?
5. What is the purpose of �Xms option of �java�?
6. What is the main difference between java.util.Date class and java.util.Calendar class?
7. What are the differences between wait and sleep methods?
8. What is the advantage of using ArrayList over Vector?
9. Explain the word �casting�
could u plz help me.. i need them very much..1. What is the purpose of CLASSPATH? How �classpath�
is used by �java� and �javac�?Classpath is the paths along which javac or the jvm searches for classes to load.
2. What is the purpose of finally block?Cleanup if something went wrong

4. Explain the difference between abstract class and
interface. When to use an abstract class and when to
use an interface?You should really google this. It's hard to answer this in 1 line

5. What is the purpose of �Xms option of �java�?Increase the java heap size
6. What is the main difference between java.util.Date
class and java.util.Calendar class?RTFM http://java.sun.com/j2se/1.5.0/docs/api/

7. What are the differences between wait and sleep
methods?sleep sleeps. Wait and Notify work together in multithreaded apps.

Could you plz help me?!?!?!I'm NEW!!!
Hi to everyone!
I'm new at java,I mean that i just started learning how to program in Java and i have a problem while compiling my fisrt program in Java!
Firstly,i have to say that i have downloaded the jre-1_5_0_04-windows-i586-p.exe and installed it in my pc.From the installation a Java folder was being created.
I used Cygwin(an editor on my PC) in order to write the program :
public class HelloWorldApp {
public static void main(String args[ ]) {
System.out.println("Hello World!");
Then after storing the program i tried to compile it using javac and it outputted :
user@owner ~
$ javac HelloWorldApp.java
bash: javac: command not found
I tried then to use sthg else(java only,not javac) and it outputted
user@owner ~
$ java HelloWorldApp.java
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorldApp/java
Well,could you plz help me and tell me where is the problem?
I mean that ,shall i use a different editor or sthg else?
Thanks in advance! : )
Good evening!!!Then save ur prog in bin
folderYou should definitely not do this.
and then compile it will surely work. Bye.You can compile it, though, after saving it to a better place. That's what the path is for. You wouldn't set the path if you were going to store everything in the bin folder.
Instead, store it in a java specific folder under My Documents (Windows) or your home directory.
Maybe you are looking for
