Use Authentication class

hi all,
i see when i downloaded the urlservices that there is a class
oracle.portal.provider.v1.http.Authentication
that can dynamically change attr in provider.xml
the question is where can i make use of the class ..
should i create a dynamic page and write java code in it that uses this or what?

Ahmed,
Take a look at the Yahoo External Application sample. This sample uses the Authentication class.
The Authentication class is used to authenticate your user against an existing external web application and then display the personalized contents as a portlet.
Take a look at both the Basic Authentication and External application samples and articles

Not able to get group name by using memberof class, getting Total groups as 0 even I am member of that group.

Not able to get group name by using memberof class, getting Total groups as 0 even I am member of that group. Through this memberof class I am trying to find full qualified name(DN) of my group.
code I have used:
//specify the LDAP search filter
               String searchFilter = "(&(objectClass=user)(CN=Username))";
               //Specify the Base for the search
               String searchBase = "";
Also I have used,
             String searchFilter = "(&(objectClass=user)(CN=Username))";
               //Specify the Base for the search
               String searchBase = "ou=ibmgroups,o=ibm.com";
But in both cases I am getting value for Total groups as 0.

Error: SHA1 digest error for javax/mail/Authenticator.class

I am using javax.mail api to sending emails.
when I calls main method of the class to send email its works perfect, but when I imports the same class in jsp its shows me above said error.
My email server requires authentication before sending mails.
please guide me how to use this class in jsp .
class code is as below :

Find all the jar files under Tomcat's installation directory and all the jar files in the jre/lib/ext directory.
Make sure only one of them includes javax.mail.* classes.
Note that setting CLASSPATH to a directory does not cause all jar files in that directory to be loaded.
Finally, make sure Eclipse isn't copying the class files out of mail.jar and packaging them with your
application.

Need info on using Kerberos classes

Does anybody know, offhand, a decent site that maybe has a tutorial or some explanation about how to use the Kerberos authentication classes that come with the JDK? I haven't looked around yet, but I was wondering if somebody knew a good place.
Thanks,
Jason

if you go to the top of this page you will notice a search engine, type in Kerberos classes and presto, you will get a result, i am sure if you were to do the same on the google homepage you would be suprised to see many websites with the info you seek.

Hi stallon,
Thanks for ur reply.Actually my application is at server2. I have an account in server1 and sending mail from server2. server1 requires authentication to send it to server3. Though we provide it is not accepting.There no errors while execution but mail couldn't be send.

Logon failure: unknown user name or bad password... ?Authenticator class?

I'm connecting to a MS Exchange server (internally) but I'm getting the following error:
........Non SSL........
POP3: connecting to host "xxxx.xxx.com", port 110
S: +OK Microsoft Exchange POP3 server version 5.5.2658.25 ready

I can get my email using Outlook because I don't have to provide a password to connect. So I left it blank in my program but I still can't
login. Does this mean that I need to use the authenticator class?
Here's the code I'm using to connect:

Using List Class in java.awt / java.util ?

have a program that:
import java.util.*;
List list = new LinkedList();
list = new ArrayList();
... read a file and add elements to array
use a static setter
StaticGettersSetters.setArray(list);
next program:
import java.awt.*;
public static java.util.List queryArray =
StaticGettersSetters.getArray();
If I don't define queryArray with the package and class, the compiler
gives an error that the List class in java.awt is invalid for queryArray.
If I import the util package, import java.util.*; , the compiler
gives an error that the list class is ambiguous.
Question:
If you using a class that exists in multiple packages, is the above declaration of queryArray the only way to declare it ?
Just curious...
Thanks for your help,
YAM-SSM

So what you have to do is explicitly tell the compiler which one you really want by spelling out the fully-resolved class name:
import java.awt.*;
import java.sql.*;
import java.util.*;
public class ClashTest
    public static void main(String [] args)
        java.util.Date today    = new java.util.Date();
        java.util.List argsList = Arrays.asList(args);
        System.out.println(today);
        System.out.println(argsList);
}No problems here. - MOD

Creating a triangle using polygon class problem, URGENT??

Hi i am creating a triangle using polygon class which will eventually be used in a game where by a user clicks on the screen and triangles appear.
class MainWindow extends Frame
     private Polygon[] m_polyTriangleArr;
                   MainWindow()
                          m_nTrianglesToDraw = 0;
         m_nTrianglesDrawn = 0;
                         m_polyTriangleArr = new Polygon[15];
                         addMouseListener(new MouseCatcher() );
        setVisible(true);
                     class MouseCatcher extends MouseAdapter
                         public void mousePressed(MouseEvent evt)
              Point ptMouse = new Point();
              ptMouse = evt.getPoint();
            if(m_nTrianglesDrawn < m_nTrianglesToDraw)
                            int npoints = 3;
                    m_polyTriangleArr[m_nTrianglesDrawn]
                  = new Polygon( ptMouse[].x, ptMouse[].y, npoints);
}When i compile my code i get the following error message:
Class Expected
')' expectedThe two error messages are refering to the section new Polygon(....)
line. Please help

Cannot find symbol constructor Polygon(int, int, int)
Can some one tell me where this needs to go and what i should generally
look like pleaseI don't think it is a good idea to try and add the constructor that the compiler
can't find. Instead you should use the constructor that already exists
in the Polygon class: ie the one that looks like Polygon(int[], int[], int).
But this requires you to pass two int arrays and not two ints as you
are doing at the moment. As you have seen, evt.getPoint() only supplies
you with a single pair of ints: the x- and y-coordinates of where the mouse
button was pressed.
And this is the root of the problem. To draw a triangle you need three
points. From these three points you can build up two arrays: one containing
the x-coordinates and one containing the y-coordinates. It is these two
arrays that will be used as the first two arguments to the Polygon constructor.
So your task is to figure out how you can respond to mouse presses
correctly, and only try and add a new triangle when you have all three of its
vertices.
[Edit] This assumes that you expect the user to specify all three vertices of the
triangle. If this isn't the case, say what you do expect.

Uploading bitmapData using FileReference class ?

Hi gurus ;)
Question nr 1.
Is it possibly to upload bitmapData to server using
FileReference class ? How should i approach this issue, is there
any ready classes available for this purpose. I'm generating
bitmaps inside my Flash/Flex App and need to store them under users
profile in server.
Question nr 2.
Can i upload files from remote server to another using
FileReference class
e.g Somehow like :
uploadURL = new URLRequest();
uploadURL.url = "
http://www.[yourDomain
fileURL.url = "
http://www.myLocation.com/myfile.JPG";
file = new FileReference(fileURL.url);
file.upload(uploadURL);
This is just an idea, sure not working ;)
Any ideas are helpful
Thx
iquaaani

I did a small application that uploads a file to the server
every hour. If the server response that a login is required to
upload the file, it goes to a login page to do the login and
retried to upload the file.
I got the server response in order to know if the file did
upload correctly or not (I have to send more form data than just
the file). I didn't try the mime type since it's not relevant for
my application and usualy this information is not very trust worthy
anyways.
I'm not sure what you mean with exceptions, if you are
referring to HTTP errors, I think there is an event for that, but I
used the IOError event for this, and it seems to work good
also.

Problem with constructors and using public classes

Hi, I'm totally new to Java and I'm having a lot of problems with my program :(
I have to create constructor which creates bool's array of adequate size to create a sieve of Eratosthenes (for 2 ->n).
Then it has to create public method boolean prime(m) which returs true if the given number is prime and false if it's not prime.
And then I have to create class with main function which chooses from the given arguments the maximum and creates for it the sieve
(using the class which was created before) and returns if the arguments are prime or not.
This is what I've written but of course it's messy and it doesn't work. Can anyone help with that?
//part with a constructor
public class ESieve {
ESieve(int n) {
boolean[] isPrime = new boolean[n+1];
for (int i=2; i<=n; i++)
isPrime=true;
for(int i=2;i*i<n;i++){
if(isPrime[i]){
for(int j=i;i*j<=n;j++){
isPrime[i*j]=false;}}}
public static boolean Prime(int m)
for(int i=0; i<=m; i++)
if (isPrime[i]<2) return false;
try
m=Integer.parseInt(args[i]);
catch (NumberFormatException ex)
System.out.println(args[i] + " is not an integer");
continue;
if (isPrime[i]=true)
System.out.println (isPrime[i] + " is prime");
else
System.out.println (isPrime[i] + " is not prime");
//main
public class ESieveTest{
public static void main (String args[])
public static int max(int[] args) {
int maximum = args[0];
for (int i=1; i<args.length; i++) {
if (args[i] > maximum) {
maximum = args[i];
return maximum;
new ESieve(maximum);
for(int i=0; i<args.length; i++)
Prime(i);}

I've made changes and now my code looks like this:
public class ESieve {
ESieve(int n) {
   sieve(n);
public static boolean sieve(int n)
     boolean[] s = new boolean[n+1];
     for (int i=2; i<=n; i++)
s=true;
for(int i=2;i*i<n;i++){
if(s[i]){
for(int j=i;i*j<=n;j++){
s[i*j]=false;}}}
return s[n];}
public static boolean prime(int m)
if (m<2) return false;
boolean x = sieve(m);
if (x=true)
System.out.println (m + " is prime");
else
System.out.println (m + " is not prime");
return x;}
//main
public class ESieveTest{
public static int max(int[] args) {
int maximum = args[0];
for (int i=1; i<args.length; i++) {
if (args[i] > maximum) {
maximum = args[i];
return maximum;
public static void main (String[] args)
int n; int i, j;
for(i=0;i<=args.length;i++)
n=Integer.parseInt(args[i]);
int maximum=max(args[]);
ESieve S = new ESieve(maximum);
for(i=0; i<args.length; i++)
S.prime(i);}
It shows an error for main:
{quote} ESieveTest.java:21: '.class' expected
int maximum=max(args[]); {quote}
Any suggestions how to fix it?

End of Page event in ALV report using SALV class[cl_salv_hierseq_table]

Hi ,
have been working on a ALV report using the class SALV cl_salv_hierseq_table
I am facing few issues pertaining to two things:
1. Displaying some subtotal text along with the subtotals.
Example refer the standard demo example: SALV_DEMO_HIERSEQ_FORM_EVENTS
Now instead of A 17 and A26 I would like to show text like Subtotal for the Carrid.for subtotals and grand totals
Like Subtotal for A 17 is : XXXXXXX
GrandTotal is : YYYYYY
2. We have a page break and a new page for every purchasing group as in the standard example SALV_DEMO_HIERSEQ_FORM_EVENTS for CARRID.
I need to display some variable values as number of documents ,total number of records etc at the end of each CARRID group before a new page starts for the next CARRID.Please note i do not want it on every page.it should only be diaplyed at the end of page whose next page would be for next CARRID.[basically at end of every carrid]Example:after displaying all details for AA need to display the number of records for that carrid at the end of the page[as page break is based on CARRID]/
Thanks
Jyotsna

at end of page event, for CL_SALV_EVENTS_HIERSEQ, has some useful parameters allowing to know where you are at the time of event
parameter VALUE is of type CL_SALV_FORM which contains public attribute IF_SALV_FORM~ACCDESCRIPTION; you can slo get contents of it
about text of total/subtotal, this is normally set in the layout

Use of classes Vs tables

Hi All,
I have e requirement where i need to select data from tables....... It was told to me that i can make use of classes instead of tables...... I am working on Inbound delivery in EWMmodule.......
can any one through some light on this....... how can i make use of classes to get data from sap tables.........
Regards,
Poonam

Hi Faisal,
Just to correct you it's "Methods of Global Persistent Classes".
Not to hide my ignorance in OOPs, but i don't think persistent classes should be used for mundane selects. It's much easier to write, maintain & troubleshoot a select construct than a persistent class
You can go through this discussion on: Why do we need Persistent Classes ?

Help using scanner class to count chars in file

Hi all, I am learning Java right now and ran into a problem. I need to use the Scanner class to accurately count the number of chars in a file including the line feed chars 10&13.
This what I have and it currently reports a 201 byte file as having 194 chars:
     File file = new File(plainFile);
     Scanner inputFile = new Scanner(file);
     numberOfChars = 0;
     String line;
     //count characters in file
     while (inputFile.hasNextLine())
          line = inputFile.nextLine();
          numberOfChars += line.length();
I know there are other ways using BufferedReader, etc but I have to use Scanner class to do this.
Thanks in advance!

Wow guys, thanks for the help! I've got a RTFMWell, what's wrong to have a look at the API docs for the Scanner class?
and directions that go against the specs I said.Is that so strange to suggest a better option? What if I ask a carpenter "how do I build a table with a my stapler?". Should I give the man an attitude if he tells me I'd better use a saw and hammer?
I'm also aware that it "eats" those chars and obviously looking for a way around that.
I've looked through the java docs, but as I said, I'm new to this and they're difficult to understand. The class I am auditing req's that this be done using Scanner, but I don't see why you demand an explanation.
Can anybody give me some constructive help?Get lost?

Customizing FD01 and FB70 using PS Class and Characteristics

Hello SAP Experts
I have the following issue:
My client has a requirement where we need to customize the Customer Master (FD01) screen and the Invoice Posting Screen (FB70). A few additional fields have to be added by creating a separate tab. I was intending to take Abaper's help and do this using user exits but I have been suggested by the cleint to use SAP PS Class and Characteristics feature to do this. Can someone please throw some light on this feature and how can i create custom fields on FD01 and FB70 screens. Is there a way we could customize these screens using PS class and characteristics. Your opinions would be much appreciated.
Please kindly give your suggestions. Thanks in advance

Joao Paulo,
Thank you for the response. I have tried to obtain some info from OSS but no luck. Tried all means but there is limited information available.
