ARP and RARP request in Java

Hello,
I'd like to send ARP and RARP request in Java, but I don't know how to.
Thanks for help.

Potentially you can find the RFCs for ARP and RARP and then code the functions at the socket level. To be a real pal, make the code into an open source library when you're done.

XFIRE - Java class from wsdl and soap request from java class

Hi,
Firstly i'm newbie programmer with little experience, so please help me if u can.
I have found an example on how to create java classes from WSDL under maven:
(...)<taskdef classname="org.codehaus.xfire.gen.WsGenTask" name="wsgen">(...)
I've created the below java class and I create new object of this class: UploadChunk up = new UploadChunk()
and up.setSomething(123) etc....
I have some service for which I have to prepare soap request manually - suitable for my service requests.
I'm doing it using dom4j to create xml documents and i rewrite values to it from my variable up.
I wonder if it is possible to do it automatically - I have UploadChunk object and I want do use xFire library somehow to produce ready or almost ready soap request. I want to do it in my code, no some ant or maven task.
So I propably need a couple line of code, when I have:
up.setSomething(123);
//////CONVERTION - CAN U TELL ME HOW TO DO THAT PLEASE? I haven't found the way :( it seems I need your help.
//////Document result =....
callService(result,namespace,qname);

Hi,
Can u Please post the WSDL..here. I remember long back i resolved this kind of issue...when i was getting "*parameters is already defined in - - -*" while using ClientGen.
Once i will get the WSDL may be i can recall it...
If u have any problem in Posting the WSDL..in Forums .. then let me know I will send my E-Mail Address...
As far as i remember ..it usually happens when we Run ClientGen task of WLS81 ON the WebService/WSDL generated by WebLogic 9.x or Above. Please let me know if this is the Case with you as well... . I remember there is a Patch for it...for WLS8 ClientGen task...I dont remember the Patch Number Exactly.
Just For testing:
Just Use WLS9.x ClientGen task On the Same WSDL
<taskdef name="clientgen" classname="weblogic.wsee.tools.anttasks.ClientGenTask" />
I am sure you will not see this issue... because the issue is there only with WLS8 Clientgen...
Thanks

IPS and IDS- ARP Inbalance-of-Requests and TCP High Port Sweep

Does anybody knows about ARP Inbalance-of-Requests and TCP High Port Sweep IPS signature? We've been receiving numerous numbers of alerts with this kind of signature in the IPS.
Actually, I'm planning to tune these events in IPS and I really need your inputs if it is safe to tune. Based on my investigation, most of the source and destination IP's are internal to our network (e.g servers, workstation and other device).
I think this is false positive incidents...
Best regards,
Carlou

This will be a normal signature to see triggered if you are watching outbound traffic from your internal network. As long as the source of the traffic is your internal hosts, and the destination is external hosts, this is likely just normal behavior.
This signature triggers when a single host sends TCP SYN packets to a number of different hosts, perhaps because of multiple web sessions going, or pop-up windows while web surfing.

Proxy Login Request on Java applets

• 10.4.5 Client
• Windows 2.3k ISA 2005 Proxy Server
• Users' fileserving to Win2.3k - ADmitMac for AD integration
The client is a test machine on which I build campus master NetInstall images. In my testing procedures I've come across a bizarre problem with Java in the browsers (IE, Safari, & FireFox).
We use ISA proxy server with web filtering, and users must authenticate to the proxy. On a new user's first use of any browser, the proxy username & password are requested, and the Add to Keychain checkbox is available. If the user checks the box, no further proxy login requests are made; the user's Keychain is updated with the proxy information.
On pages with Java applets, however, each and every applet will ask for a proxy login, but the login window does not offer a Add to Keychain checkbox! If a page has 15 applets on it, the user will be asked 15 times to authenticate against the proxy.
Naturally, this is a BIG problem, especially when several of the sites our teachers use in classes and labs contain many Java applets.
On the web, there is almost nothing concerning setting up Java with proxy servers, as all Apple Java from v. 1.4.2 onwards picks up proxy information from the system's network settings.
On the Apple Developer site, Tech Note QA1263 demonstrates a way of setting HTTPS proxy settings by entering text strings in the 1.3.1 and 1.4.1 Plugin Settings apps Java Runtime Parameters. The same capability exists in the J2SE 5.0 Java Preferences app, too. Unfortunately, the Java applets do not use HTTPS, so far as I can tell, so this remedy is useless.
Any clues I can pursue? Any help or fixes?
Thanks in advance!

After some more research with the J2SE 5.0 Java Preferences app, I turned on the Java console, booted Safari and went to my favorite Java applet - babynamewizard. This is the output of the console log. From what I can glean, the plug-in sees the proxy server settings as it should, and reports them.
In addition, the J2SE 5.0 Java Preferences app allows you to turn off all security settings. No change in behavior.

Initiate request from java class

Hello
I got a peculiar question
My web container contains the following
a JSP page[b] page1.jsp
second JSP page page2.jsp
A servlet PushPage
A java class ContactServlet
What I want to achieve is when browser is displaying page1.jsp. The ContactSevlet.java class calls the servlet PushPage which redirects to page2.jsp
I am able to successfully load the servlet from ContactServlet.java since I am able to print the response(the contents of page2.jsp) on to console.
But the page2.jsp does not display on the browser, it still displays page1.jsp after servlet completes its function.
Any idea how can I make the page2.jsp to display on the browser?
In other words i should make the Servlet feel like the request has come from page1.jsp for page2.jsp.
The code for servlet and java class are below
package testpackage;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
* Servlet implementation class for Servlet: PushPage
public class PushPage extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
     public PushPage() {
          super();
     protected void processAll(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          response.sendRedirect("http://localhost/rimpush/page2.jsp");
     protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
           processAll( request, response);
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          processAll( request, response);
/*Java class*/
package testpackage;
import java.io.*;
import java.net.*;
import javax.servlet.http.HttpServletRequest;
public class ContactServlet {
     public ContactServlet(){
     public static void main( String [] args ) {
          /*Call the servlet PushPage*/
          try {
            URL url = new URL("http://localhost/rimpush/PushPage");
            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
        catch ( MalformedURLException ex ) {
            // a real program would need to handle this exception
        catch ( IOException ex ) {
            // a real program would need to handle this exception
}Any idea would be gracefully appreciated
Thank you.

Your ContactServlet program does makes a request to the "PushPage" servlet independant of the browser. In fact you may as well have just opened up a new browser window - it is the same effect.
In most cases the only way you can put a new page in the browser is if the browser requests it. So if you want something to be loaded into the browser with page1.jsp displayed in it, then that browser needs to make a request to the server.
The standard way of doing this is to either use a meta-refresh tag on the page, or a javascript window.setTimeout.
If you want a "push" technology, you might take a look at [url http://www.pushlets.com] pushlets . I haven't actually used them, but they might be applicable in this case.

BUGS and FEATURES REQUESTED. Please add to it.

I've been using the z10 for the past couple weeks and wanted to start a thread of comprehensive Bugs and Features Requested.
I've labeled Bugs by letters (A,B,C...) and Features Requested by numbers (1, 2, 3...) so that others can add sequentially.
BUGS
(Not listed in any particular order)
(A.) Contact App adds current date as birthday. When I edit my contact, the current date gets listed as the birthday in local contact.
(B.) Duplicate telephone numbers listed. Telephone numbers show up twice in my Contacts (e.g.., if I have the contact's cell saved in (000) 123-4567 format and the person has the number listed in Facebook, I get a duplicate entry of +10001234567).
(C.) Telephone numbers and emails are not actionable in Web pages. In webpages, I can't click on telephone number to call (e.g., I look up a phone number for a restaurant). I should be able to easily call or copy into the Phone App or E-mail App.
(D.) Auto capitulation for words on the word substitution list is wrong. For example, when the word substitution contains more than one word. I have "ru" change to "are you" but if the first letter is capitalized (R) then both words become capitalized words (Are You). I used to have shortcuts like "mysig" to create email signatures with legal disclaimers but I can't do that now.
(E.) Backspace delete doesn't work consistently. The Shift+Delete function seems only to work after moving the cursor. This feature is the Alt+Del action to delete words after the cursor.
(F.) All Emoticons do not list. Emoticons do not all fit on the the two screens (lists) of emoticons. I.e., two columns are missing from view and can be seen when sliding (swiping) between the lists. Also, sometimes when I select an emoticon, it doesn't correspond with the picture of the one I intended. I believe this error is related. As a separate note, there should be a way to see the underlying symbols of the emoticon. (Often times, other people don't have BlackBerrys so I'd like to know what symbols would be sent--my prior 9800 would show the characters as i scrolled through them).
(G.) BlackBerry keyboard doesn't always work in input fields. E.g., certain Web pages. (I found a work around; two finger swipe up from the bottom makes the keyboard appear)
(H.) Sent messages stay unread. This seems to be an issue when an app sends an email (e.g., share article). The email with the sent indicator (checkmark) stays bold and I have listed 1 unread email. I can't mark as read/unread but if I delete the sent email, my unread message gets cleared.
(I.) Contact already added but I get the option to add instead of view contact. For some contacts, I get the option to add to contacts in the action menu cascade when that person is already in my address book. This bug is for emails and text messages.
(J.) Cannot call from text message. When I hold a text message and select call under the action menu cascade, the OS opens up the phone app but doesn't call.
(K.) Composing messages by name. When composting messages, the input must be by first, middle and last name. It should be, instead, by string and include nickname. E.g., if the person's name is "Andrew B. Cameron" I must type the name in as such. I can't type in "Andrew Cameron" or "Andy Cameron."
Features Requested and Suggestions for Improved User Experience
(In no particular order)
1)      Option to reply in different ways from the Call List. Be able to select a name in a call list and have options to call, text or email the person. The action menu allows calls to other numbers but I can't choose to text or email the contact instead. Sometimes, I missed a call and want to reply via text because I’m not able to talk. (Long hold on the Torch 9800 trackpad button brought up the action menu allowing me to call, text, view history, add to speed dial, e-mail, delete, etc.)
2)      Option to reply in different ways from the Hub. Related to above, when selecting an item in the hub, have the option to contact the sender or caller with multiple different ways.
3)      Only show number once in contacts application. Tap on the number to bring up the "action" cascade menu with options to call or text the number. Why is the same number listed twice (once to call and below again to text it)?
4)      Timestamps for individual text messages. I can't tell exact time on individual text message if it comes in near the time of another text. All messages are in one "bubble."
5)      Ability to select MMS or text for a message. Sometimes I write a text longer than 160 characters and I prefer it to be sent in one message (i.e., MMS mode) rather than being broken into one or more standard text messages. I had this ability with my 9800.
6)      Send button should be moved for text messages!!! Why the heck is it right underneath the delete button?!? Or next to the period button? I often times have accidentally hit send when composing text. It's very annoying and embarrassing. (Also, what happened to the ability to hit enter for a return carriage to next line?)
7)      Bigger magnifying glass. My finger is often over the area I need to place the cursor. I find it difficult and erratic to place the cursor.
8)      Select all option. Add the option to select all text in action menu cascade.
9)      E-mail recipients and message headers. Difficult to tell if you are one of many email recipients. Can we have a way to pull the email down to see the list of recipients rather than have to click to expand the header info? I know this request is a little picky, but that's how it was done in the previous BlackBerry OS which I preferred; it is easier and faster to pull the e-mail down and 'peek' to see which e-mail box received the message, message status, from and to fields. This change would be consistent with BB's flow/peek rather than click.
10)   Browser navigation. Hold down back arrow to get a list of recently visited websites similar to a desktop browser.
11)   Dark/Night mode. A night mode (maybe in the drop down menu) to change all the white and bright backgrounds to black or dark which would be helpful when reading/viewing things at night in bed/etc.
12)   Number of contacts. Ability to see how many contacts I have.
13)   What happened to groups or categories? I'd like to have back the ability to filter or see categories and also a way to contact everyone in a category. E.g., family or friends or coworkers, etc.
14)   Shutter sound mute. I was at a wedding and wanted to take pictures during the ceremony but the shutter would was too loud.
15)   East Asian Language Input. I bought my parents two Samsung Galaxy S3 phones over the weekend because they need Korean input (and the Kakao talk app). (BTW, S3 is a great phone but I prefer the Z10 after having the weekend to use the Android phones).
16)   Ability to freely place icons on the homesreen. Currently, icons are forced top left-right-to-bottom. I prefer to space my icons out.
17)   Add a contact to the homescreen. I'd like to place a shortcut (similar to a Webpage) to the homescreen for a contact which will open up the contact. Android allows this feature and so did my previous 9800.
18)   Search Contacts by nickname. The contacts app doesn't allow me to search by, e.g., Andy, even if I have that as my contact's nickname. The previous OS allowed this type of search which was very helpful.
Finally, as a note, I've been using the BlackBerry Z10 for the past 2 weeks and it's a great platform. I just bought two Samsung Galaxy S3 phones over the weekend for my parents so they could use the Korean language input and related features so I spent a lot of time with the Android platform, setting it up and teaching them how to use it. The S3 is a great phone too.
I prefer, however, the way BlackBerry has done their OS 10 and the integrated management of messages.
It's too bad that BB doesn't have Korean input and apps like Kakao Talk or I would have considered it for them.
The BlackBerry 10 is a great platform and I look forward to the continual improvements that will only make the experience better.

This is a great post.
I couldn't have written it myself better.
I'm also in dying need of Korean input as I can't communicate with my Korean friends.
But I second every point.
I hope the tech teams are reading this.

Using Runtime exec() to open and close process like java or javac

Hi, I m a student who is learning IT and is wondering if

Can someone post the code to do so here?Thank you

Problems with page and event paramters in java portlets

Hi there!
Following the documentation in "A primer on Portlet Parameters and events" and "Adding Parameters an Events to Portlets" I tried to develop two portlets (who will be at the same page), one showing some content of a repository (with possibilities to browse throw it) and another showing a sitemap of the repositories whole content, presenting links to the content's pages to be shown in the content portlet.
So I added:
1. a page parameter called pageMenuID to identify the current content page to be shown in the content portlet
2. an input parameter for content portlet called portletMenuID. This input parameter is mapped to the page parameter pageMenuID
3. an event for content portlet called changeContent with output parameter contentMenuID. When this event rises, "go to page" is set to the current page and the output parameter contentMenuID is mapped to the page parameter pageMenuID.
4. an event for sitemap portlet called changeContentFromSitemap with output parameter sitemapMenuID. When this event rises, "go to page" is set to the current page and the output parameter sitemapMenuID is mapped to the page parameter pageMenuID.
This is the code for some constants and a function to build the links in the content portlet, that I want to use:
// page parameter (shouldn't be used here)
private final static String pageParamMenuID = "pageMenuID";
// parameter names as given in providers.xml:
// portlet input parameter
private final static String inputParamMenuID = "portletMenuID";
// event name
private final static String eventName = EventUtils.eventName("changeContent");
// parameter name for event parameters
private final static String eventParamMenuID = EventUtils.eventParameter("contentMenuID");
String getEventUrl( PortletRenderRequest portletRequest, long menuID) {
NameValuePair[] eventParams = new NameValuePair[2];
eventParams[0] = new NameValuePair(eventName,"");
eventParams[1] = new NameValuePair(eventParamMenuID, "" + menuID);
try {
return PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(),
eventParams,
true,
true);
} catch (Exception e) {
return "null";
This is the analog code from the sitemap portlet:
// page parameter defined on "edit page mode" (shouldn't be used here)
private final static String pageParamMenuID = "pageMenuID";
// parameter names as given in providers.xml:
// event name
private final static String eventName = EventUtils.eventName("changeContentFromSitemap");
// parameter name for event parameters
private final static String eventParamMenuID = EventUtils.eventParameter("sitemapMenuID");
String getEventUrl( PortletRenderRequest portletRequest, long menuID) {
NameValuePair[] eventParams = new NameValuePair[2];
eventParams[0] = new NameValuePair(eventName,"");
eventParams[1] = new NameValuePair(eventParamMenuID, "" + menuID);
try {
return PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(),
eventParams,
true,
true);
} catch (Exception e) {
return "null";
But what actually happens is nothing. I also tried to construct the links with EventUtil.constructEventLink() with the same result. Checking the produced html-code in the browser shows that the same URLs are produced. So I'm of the opinion, that proper event links are created.
After checking the sent and received request parameters I came to the conclusion, that the event output parameters are never mapped to the page input paramters, as they should. So I changed the code to the following:
// page parameter (shouldn't be used here)
private final static String pageParamMenuID = "pageMenuID";
// parameter names as given in providers.xml:
// event name
private final static String eventName = EventUtils.eventName("changeContentFromSitemap");
// parameter name for event parameters
private final static String eventParamMenuID = EventUtils.eventParameter("sitemapMenuID");
String getEventUrl( PortletRenderRequest portletRequest, long menuID) {
NameValuePair[] eventParams = new NameValuePair[1];
eventParams[1] = new NameValuePair(pageParamMenuID, "" + menuID); <-- Note that the page parameter and not the event output parameter is used here -->
try {
return PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(),
eventParams,
true,
true);
} catch (Exception e) {
return "null";
Now everything works fine, including addition of persistent private portlet parameters and further input/page/event parameters as well as working with a third portlet with performs a search (and presents the search results as links which change the content in content portlet).
But this is actually NOT the way it should work: The names of the page parameters are hard-coded in the portlets, so the roles of page designer and portlet developer are not separated in the way it is presented in the documentation. I coulnd't find a way to map the event output parameters to the page parameters to work this out.
Now I wonder whether there's some known bug in PDK or perhaps a mistake in the documentation or wether I'm just missing doing the right things. I've already read some postings in this forum concerning this problem (for example how to change the query??? but I think I've done all the things that are suggested there (checked the entries in provider.xml and the proper mapping of page parameters, public (input) portlet parameters and event output parameters, also the way I read the received request parameters and build the links)
Has anybody an idea what's wrong here?
Best regards
Torsten

Hi Amjad,
thank you very much for time and effort you spent on helping me solving this problem.
Unfortunately, I think I already tried what you suggest in your answer, but without success. From my experience, the following two calls:
1.
<%!
private static String eventName = "changeContent"
private static String eventParamID = "menuID"
String getEventUrl(PortalRenderRequest prr, long menuID) {
NameValuePair[] eventParams = new NameValuePair[1];
// no addition of eventName in the array
eventParams[0] = new NameValuePair(eventParamID, "" + menuID);
return EventUtils.constructEventLink(prr, eventName, eventParams, true, true);
%>
<a href="<%= getEventUrl(portletRequest, 1234) %>">some link for ID 1234</a>
2.
<%!
private static String eventName = EventUtils.eventName("changeContent");
private static String eventParamID = EventUtils.eventParameter("menuID");
String getEventUrl(PortalRenderRequest prr, long menuID) {
NameValuePair[] eventParams = new NameValuePair[2];
eventParams[0] = new NameValuePair(eventParamID, "" + menuID);
eventParams[0] = new NameValuePair(eventName,"");
return PortletRendererUtil.constructLink(prr, prr.getRenderContext().getEventURL(), eventParams, true, true);
%>
<a href="<%= getEventUrl(portletRequest, 1234) %>">some link for ID 1234</a>
produce identical links. I took the second way because it is easer to add private portlet parameters to the link: just as additional NameValuePairs in the eventParam- Array (name constructed with HttpPortletRendererUtil.portletParameter()), instead of constructing the link "by hand" as mentioned in the javadoc for constructEventLink(). I have to add these private portlet parameters here because when an event from a private parameters owning portlet is fired, the private parameters are lost (in difference to when an event from ANOTHER portlet is sent).
So I think, when you also look closely to the code snippet I added in the first posting, I made shure that I added the name of the event and not just the event parameters to the link.
I hope that I understood your answer right. Perhaps you have another idea what might be wrong. Thank you again,
best regards
Torsten

Difference between customizing request and workbench request?

Hi ,
What is the difference between customizing request and workbench request?
please reply.........

HI,
Workbench Requests
When you change a Repository object of the ABAP Workbench, a query window appears in which you need to specify a Workbench request. You can only save the changes if you have assigned the object to a change request.
Workbench requests and the tasks assigned to them are normally used to record changes to Repository objects and Customizing for all clients. However, you can also include client-specific Customizing.
Whether the changes to Repository objects are transported depends on whether a transport route is defined from the current SAP System for the package of these objects. From the system settings, the system automatically determines whether the change requests are transportable and to which target system they should be transported.
Customizing requests
Customizing requests record client-specific Customizing settings made in a single client (the source client of the request).
Automatic recording of configuration activities in the Customizing work for a client can be activated or deactivated for each client with Client Control. If automatic recording is active, a query window appears when you change Customizing settings, asking you to specify a Customizing request.
Whether Customizing requests are transported or not, does not depend on the objects entered, as is the case with Workbench change requests. The Customizing requests in an SAP System (or in a client if you use Extended Transport Control) are either all transportable or all local, depending on the system setting. The system uses the standard transport layer to determine automatically whether the change requests are transportable and to which target system they should be transported. However, you can change this manually.
pl reward if it helps.
Thanks

What are the pros and cons of installing java+abap stack for portal?

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

Thomas Pham

Difference between task request and change request

What is the difference between task request and change request during sap implementation. In general how many tasks will generate during a normal company inmplementation by any functional consultant?

Hi,
Change request and task request are same.But generally change request is generated during newly created objects or reports that are transported and task request is used when u regenerate the change request by modifying that object again and transporting it in new change request.
A particular change request may contain multiple number of task request but that number depends upon number of objects u transfer during generation and transportation.
Pls do reward points if ans is useful.

Suhas.

Do i need a network card to install and run a local java web server

Friends,
Do i need a network card in my computer to install and run a local Java Web Server or any Web Server.

network cards are only for connecting equipment together... you can set up a webserver without any more equipment than you have already! Indeed Tomcat... BUT you would be better off with apache for production stuff. It depends what you need to serve... if its mainly static pages (i guess it probably isn't) then apache will be enough by itself; but if you need to serve dynamic pages (JSP, Servlet blah blah) then you will need tomcat. Tomcat has it's own webserver and its perfectly ok for testing or low-load stuff, but you can integrate with Apache (a moderately compex task, but do-able, see tomcat-user forum off of apache site) for greater stability, and you don't have to show the port in the URL... Don't set up a webserver on any pc that contains stuff you don't want hacked into... it becomes very succeptible when the service is up...

I am trying to install the OS Mavericks upgrade on my MAC and it requests for me to enter an administrator password. I do not use an an administrator password on the machine. Any ideas how to resolve this?

I am trying to install the OS Mavericks upgrade on my MAC and it requests for me to enter an administrator password. I do not use an an administrator password on the machine. Any ideas how to resolve this?

If you bought the machine new yourself, and did not enter a password when configuring it, leave the field blank.
If you bought it used, then you need to reset the password, as described here:

How SDA and DDA works in Java Card?

Hi Friends,
I want to know how exactly SDA and DDA works in Java Card technology..
Yes, i know that SDA (Static Data Authentication) is valid for every transactions, but the key used is always same for every transaction made..
and DDA (Dynamic Data Authentication) uses dynamic key for every transactions, it means that one key is valid for one transaction..
But, i'm a little bit confused how this is implemented in Java Card..
Is it related with SCP01 and SCP02?..
Please help me regarding this..
Thanks in advance

Hi,
I want to know how exactly SDA and DDA works in Java Card technology..This is an EMV concept and as such is not implemented in Java Card as such. You would have to create an implementation to be able to use SDA and DDA.
But, i'm a little bit confused how this is implemented in Java Card..
Is it related with SCP01 and SCP02?..It is not implemented natively in Java Card and are not related to SCP. SDA and DDA are for the EMV card application (card application data updates) and SCP is for the card manager (card content updates). While they could be considered similar concepts, they are not related in a Java Card sense.
Cheers,
Shane
