How can i encrypt an ddecrypt a string using java

please if anybody help me with a small example and with code
thanks
ravi chandra

hi,
of course there are better ways to crypt your code, but the following 2 functions do their job....
as far as i know java has an own api for crypting stuff.
private String GetEncryptedString(String aCryptedString)
String result = "";
String str = aCryptedString;
int[] asciiArray = new int[str.length()];
for(int i = 0; i < asciiArray.length; i++)
asciiArray[i] = (int)str.charAt(i);
char tempChar = (char)(asciiArray[i]+3);
result = result+tempChar;
return result;
private String GetDecryptedString(String aString)
String result = "";
String str = aString;
int[] asciiArray = new int[str.length()];
for(int i = 0; i < asciiArray.length; i++)
asciiArray[i] = (int)str.charAt(i);
char tempChar = (char)(asciiArray[i]-3);
result = result+tempChar;
return result;
andi

How can we get requester's user id using java code

Hi,
How can we get requester's user id using java code?
eg: If i had logged in as xelsysadm and request a resource for user uid101 on the userid field it should display uid101 and not xelsysadm.
also,
I have a resoure "A" which on revoking should also revoke resources B and C. How can it be done. Resource A, B, and C are 3 different resource objects.
==Thanks,
doki

Ok, so there is a way, but it's not available during submission. You can use the findRequests api. From the result set, get the "Requests.Consolidated Data Value" value. In this information, you will get an xml formatted data. It provides the list of users on the request on the left side after submission. After the request is completed, this value is available. Upon completion, you could get the request information, get this value, and parse the information for user ids.
In the same adapter, use the following API:
formIntf.setObjectFormData(objInstanceKey, formHash)
The formHash is a hashtable containing the field name on your object form, and the values you wish to populate it with. You could create a textarea box on your object form and populate the userids for who the request is for.
However, this makes absolutely 0 sense. When you get a request, the list of userids are listed right there on the request.

How can I encrypt/decrypt data in Forms using a specified Package?

Hi All,
I have searched in the Internet for ecnrypting/decrypting data in Forms.
That is when I want to query the data outside the Form Application it will be encypted, otherwise if I want to query it in the form application it will be dycrypted
I found this package:
CREATE OR REPLACE PACKAGE Encrypt_pkg AS
FUNCTION encrypt (p_text IN VARCHAR2) RETURN RAW;
FUNCTION decrypt (p_raw IN RAW) RETURN VARCHAR2;
END Encrypt_pkg;
CREATE OR REPLACE PACKAGE BODY Encrypt_pkg AS
-- All VARCHAR2 inputs are padded to multiples of 8 charaters,
-- with the encryption key also being a multiple of 8 charaters.
-- The encryption key and padding characters can be altered to suit.
g_key RAW(32767) := UTL_RAW.cast_to_raw('12345678');
g_pad_chr VARCHAR2(1) := '';
PROCEDURE padstring (p_text IN OUT VARCHAR2);
FUNCTION encrypt (p_text IN VARCHAR2) RETURN RAW IS
l_text VARCHAR2(32767) := p_text;
l_encrypted RAW(32767);
BEGIN
padstring(l_text);
DBMS_OBFUSCATION_TOOLKIT.desencrypt(input => UTL_RAW.cast_to_raw(l_text),
key => g_key,
encrypted_data => l_encrypted);
RETURN l_encrypted;
END;
FUNCTION decrypt (p_raw IN RAW) RETURN VARCHAR2 IS
l_decrypted VARCHAR2(32767);
BEGIN
DBMS_OBFUSCATION_TOOLKIT.desdecrypt(input => p_raw,
key => g_key,
decrypted_data => l_decrypted);
RETURN RTrim(UTL_RAW.cast_to_varchar2(l_decrypted), g_pad_chr);
END;
PROCEDURE padstring (p_text IN OUT VARCHAR2) IS
l_units NUMBER;
BEGIN
IF LENGTH(p_text) MOD 8 > 0 THEN
l_units := TRUNC(LENGTH(p_text)/8) + 1;
p_text := RPAD(p_text, l_units * 8, g_pad_chr);
END IF;
END;
END Encrypt_pkg;
** Now How can I use this package to encrypt/decrypt data in the form as I said Plz???

<p>Read this article and go to chapter 2.3.2.</p>Inserts, Update and Delete orders are managed by a stored procedure. In the sample dialog, the Select is handled by the emp_pkg.emp_query() stored function:
PROCEDURE emp_query(emp_data IN OUT emptab) IS
    ii NUMBER;
    CURSOR empselect IS
      SELECT empno, ename, job, sal, comm FROM emp
       ORDER BY ename ;
BEGIN
    OPEN empselect;
    ii := 1;
    LOOP
      FETCH empselect INTO
        emp_data( ii ).empno,
        emp_data( ii ).ename,
        emp_data( ii ).job,
        emp_data( ii ).sal,
        emp_data( ii ).comm;
      EXIT WHEN empselect%NOTFOUND;
      ii := ii + 1;
    END LOOP;
END emp_query;In your case, all you have to do is th use your decrypt() function in the cursor definition:
    CURSOR empselect IS
      SELECT decrypt(empno), decrypt(ename), decrypt(job), decrypt(sal), comm FROM emp
       ORDER BY ename ;
...For Insert and Update events, use the crypt() function in the related stored procedures.
PROCEDURE emp_insert2(t IN emptab) IS
BEGIN
    FOR i IN t.first..t.last LOOP
     INSERT INTO emp (empno, ename, job, sal, comm)
     VALUES(crypt(t(i).empno), crypt(t(i).ename), crypt(t(i).job), crypt(t(i).sal, t(i).comm));
     END LOOP ;
END emp_insert2;Idem for the Update procedure.

How can I authenticate to a XI server using java via SOAP (SAAJ)

Hi everybody!
I need to connect (SOAP) to a XI server using JAVA
I'm using SAAJ api.The problem is XI server need authentication but I can't found the way to do it! this is a part of code
SOAPConnectionFactory soapConnFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnFactory.createConnection();
URL destination = new URL("https://host:port");
SOAPMessage reply = connection.call(message, destination);
(message is the XML code)
but the application has the following error:
com.sun.xml.messaging.saaj.client.p2p.HttpSOAPConnection post
GRAVE: SAAJ0009: Fallo en el envío del mensaje
I think, maybe is a authentication problem, because the XI server needs it. But I don't have idea how can I send the user and pass
Any IDea???? please
the libraries are ok imported, I use netweaver to develop-
thanks in advantage

hi Leslie,
there are only a few of these errors,
you can try this:
http://www.oxygenxml.com/forum/ftopic1103.html&sid=0abee8c719481a3dd783ff7d5cd84105
are you sure your URL is accessible from your location?

How can i turn off the computer remotely using java?

is it possible to use a java code for turning off the computer remotely by other computer in LAN?
or if it is not possible how can i achieved that goal?
thanx

Well, if you're running linux you could use Runtime.getRuntime().exec() to execute 'halt -p', if the process was being run as root. Not terribly elegant but I suppose it would work. Although I wouldn't want an unattended process running as root.Yes, this is how you can do it, but on Windows machines as well. I'll go into pseudocode:
App1: Server (running on every lab machine)
open server socket on port X
wait for connection
verify connection is yourself so that not everyone can shut it down
if not, wait for connection again
if it is, run halt for linux or shutdown for windowsApp2: Client (running on just your computer)
open a socket to each machine running the server app (or you could use multicasting)
validate yourself however you did that
close socketThere are some implications of this though - unless your validation mechanism is decent, pretty much anyone can shut down anything they want. Also, if you don't check for a logged-in user, you may destroy someone's work. Just keep those in mind.
Also, if it is a Windows setting, there are usually better ways to do this - a well-managed windows network has built-in functionality to shut down computers remotely.

How can i encrypt "String" which present a Password

i have a String which present password, how can i encrypt the password while i save it to an XML file and how i decipher the password when i load it from the XML file.
Thanks

You don't generally encrypt passwords. You simply hash them. There should rarely, if ever, be a reason to decrypt a password.

How to search for upper/lower case using string using JAVA!!!?

-I am trying to write a program that will examine each letter in the string and count how many time the upper-case letter 'E' appears, and how many times the lower-case letter 'e' appears.
-I also have to use a JOptionPane.showMessageDialog() to tell the user how many upper and lower case e's were in the string.
-This will be repeated until the user types the word "Stop".
please help if you can
what i have so far:
[code]
public class Project0 {
public static void main(String[] args) {
String[] uppercase = {'E'};
String[] lowercase = {'e'};
String isOrIsNot, inputWord;
while (true) {
   // This line asks the user for input by popping out a single window
   // with text input
   inputWord = JOptionPane.showInputDialog(null, "Please enter a sentence");
   if ( inputWord.equals("stop") )
    System.exit(0);
   // if the inputWord is contained within uppercase or
   // lowercase return true
   if (wordIsThere(inputWord, lowercase))
    isOrIsNot = "Number of lower case e's: ";
   if (wordIsThere(inputword, uppercase))
     isOrIsNot = "number of upper case e's: ";
   // Output to a JOptionPane window whether the word is on the list or not
   JOptionPane.showMessageDialog(null, "The word " + inputWord + " " + isOrIsNot + " on the list.");

How can i execute excelsheet without giving path in java

Hi,
How can i execute excelsheet without giving path in java, through this code, you can open the notepad but
I want whereever the excel is installed in your machine , fine and open excelsheet without given absolute path.
class ExecuteCommand{
public static void main(String d[]){
     Runtime r = Runtime.getRuntime();
     Process p= null;
     try{
     p = r.exec("notepad");
          catch(Exception e){
               System.out.println("error");
If you know please send me your idea and code samples.
regards
Mohan kumar

just execute the exelfile with the Windows "start" command:
Runtime.exec("cmd /c start "+excelFileName);But this requires that Excel is the default application for the Excel file type (*.xls). You can test this by simply typing "start myTestExcel.xls" in a dos box.
