How to Implement JCRE,JCVM as well as JC api ??

Hi ,
i am a member of Sim Card Development team but i dont hv any idea abt how to implement JCRE,JCVM & JC api as i have got the resources from different card manufacture in that they hv implemented these three things ?so my question is that..
1.is sun java providing any help for implementing these 3 things to card manufacture.
2.or sun java will implement the 3 things according the requirement of card manufacture.
3.or sun java only provide the specs & card developer has to implement everything.
4.is sun java selling these 3 things implementation to 3rd party if yes whats the procedure for that.[[/b]i]

plz help on this ...bkz soon i hve to reach conclusion

1.is sun java providing any help for
implementing these 3 things to card manufacture.
May be but I don't think so.
2.or sun java will implement the 3 things
according the requirement of card manufacture.No. I never heard of that.
3.or sun java only provide the specs & card
developer has to implement everything.
That is the usual way. In most cases java card implementors are also member of the Java Card Forum (http://www.javacardforum.org) which will give them the ability to influence the further development of the JavaCard specifications.

  • How to implement Sync-Sync scenario in BPM? Please help!

    Hi Experts,
       I have a Sync-Sync scenario (SOAP - RFC) where both sender as well as receiver are synchronous.
       I have created outbound sender sync interface, abstract sender sync interface, Receiver abstract sync interface and Receiver inbound sync interface.
      In BPM I have started with Receive step.
      But in receive step I can give either Async Abstract interface or Open Sync-Async bridge. I am confused!
      How to implement my scenario in BPM?
      It will be really great if somebody can send me the step by step info or doc.

  • How to implement this function in JSP/Servlet env?

    Hi all,
    I working on a project, it provides functionality to upload file using JSP/Servlet. In the first JSP page, there is file location and submit button. After user select a file to upload and click submit button, a message, like "sending file to XXXX", will be shown on the screen. Once uploading and validation are done on the server-side, a successful/error msg will be shown to user.
    Here I have a question for the "sending..." msg and the successful/error msg. They should be put in one jsp page or in two separate page? how to implement them?
    Thanks for any help!
    Tranquil

    For the sending message... Well, the thing is, when you click submit, it's sending the file to the server and the server is processing it, and this is all done before the "complete" page is sent to the server. So one would need to use some Javascript on the page before the actual submit happens to show some message. This is done on Ebay when you put something for sale, you can upload an image, and there is a little popup message telling you that it's uploading, and it is removed when the process is done. Now, I'm not sure the exact details of how this works, but my educated guess is this:
    1) The onsubmit function of the form checks that the file upload fields have a value (no need to popup a message if no file upload, since that's what usually takes the time, although it could just be assumed there is a file). If a file is to be uploaded, or just want to show the message anyway, a new popup window is opened with the window.open method and the "sending" message is shown (either written via Javascript or just load a small web page to the window).
    2) The popup window, since you can't transfer the window object from the form page to the next page, has to check window.opener for some value that the success/error page would have to set. The success/error page could use it's body onload function to set a variable in it's own window object to denote that the page is loaded. The popup window can use a looping check using setTimeout or setInterval in Javascript to check for window.opener.isLoadedVariable to be present, and if so, close itself.
    I've never done that, but I see no reason why it wouldn't work.

  • How to implement an independent static stub client ? Please, help

    Hi everybody!
    I'm using the jwsdp1.2 and i got the static stub tutorial client to test my webservice. It works fine! However, i tried to compile the client code separately and it didn't worked. The jvm can't find the webservice class. So, the questions are:
    - How to implement an independent static stub whithout the ant help?
    - How can the client get the endpoint to create the proxy?
    - Must I use any javax.xml.rpc interface (call or service maybe) to do the job?
    - Could anybody show me some sample code?
    Well, that's it. I'm waiting for some answer. Please, help me.
    Tks in advance,

    Can you explain what you mean by "independent static stub" ?
    JWSDP Tutorial explains all the steps required to create a static stubs client and invoke the service. In addition, https://jax-rpc.dev.java.net/whitepaper/1.1/index-part2.html#Scenario2 explains the detailed steps to achieve the same from command line.

  • How to implement wafer mapping using LabVIEW?

    Hello LabVIEW Masters!
    I am having an incoming project which includes controlling and gathering information from a PROBER. One of the difficulties I am having now is how to implement a WAFER MAP using LabVIEW. According to my customer requirements, the wafer element ranges from 6k to 23k. I guess doing all the element (one die = one led ctl/indicator) will be a hell of a task, especially on how to effectively manipulate each elements. Does anyone have better idea on how to this?
    Please, I badly need your help.. 
    Thanks and Regards,
    Dennis DG
    Solved!
    Go to Solution.

    Hi Dennis,
    Is it okay if you send to me the working VI also?
    No, it's not ok. I made that program for my customer...
    As I am not too familiar in using intensity graph.
    That's no reason to hand over programs for free...
    My customer also request me that if the cursor hover on the wafer map, he wants the x,y corrdinates to be displayed.
    I also have such a feature. Did you notice the little yellow cursor near the center of the wafer? One could easily change that to use a MouseMove event instead...
    He also wants to select some elements in the wafer map and come up with the coordinate values to do some testing.
    That's related to the cursor thing...
    Some points:
    - You have a customer that pays you. Why should I offer work for free?
    - You can send me contact dates of your customer, I will make him an offer...
    - When you take an job to provide software you should be able to code the software...
    - The VI(s) are now some years old. I didn't code so well back those days and don't want to hand out those VIs as they are right now.
    - I included some "license management" deep inside that program, I would have to remove this and spend time on testing afterwards...
    - The VIs are based on the PROBER output format used by the customer. All the file handling has to be changed for/by you...

  • How to implement google search in portal application

    Hi,
      I am using  "http://api.google.com/GoogleSearch.wsdl" file to implement google search in portal application. but i am not able to get the search result. how to implement google search. is this "http://api.google.com/GoogleSearch.wsdl" is vaild now ?. how to achieve the soultion.
    Regards,
    Shanthakumar.

    Hi Shanthakumar,
    The "GoogleSearch.WSDL" is no longer available as google has replaced it with the new AJAX based searching and they have eventually removed it from public use as well from 7th September 2009. So, I would imagine you would not be able to use the earlier WSDL file for google search. You might have to look in using the new "AJAX Search API". For more information have a look the following links. You can notice "No Longer Available" at the top of the page.

    Hi Timo,
    Thanks for response!
    But as i read from the following url: http://docs.oracle.com/cd/E15051_01/apirefs.1111/e10653/oracle/jbo/ViewObject.html, the setQueryTimeOut(int timeOutMills), the timeOut is mentioned in milliseconds. Please correct me if I am wrong.
    and i have overriden the executeQuery() method in the View Object Impl class as shown below:
    public void executeQuery() {
    Map sessionScope = ADFContext.getCurrent().getSessionScope();
    sessionScope.put("MyQuery", this);
    try {
    super.executeQuery();
    } finally {
    sessionScope.remove("MyQuery");
    throw new JboException("Query Taking too long to respond");
    and in the JAVA class i am calling the above method like this:
    monitor.setQueryTimeOut(6);
    monitor.executeQuery();
    But the issue is:
    1. The above exception message is getting carried forward to other pages as well. I mean somewhere in the session/ADFContext this message is being saved and error comes up/pops up when i click on other tabs of the page. How do i clear this?
    2. The above exception message is coming for the first time but when i click the 'Submit' button second time, i am getting the results and also the message that 'Query is taking too long to respond'. This should not be the case, everytime it should show the same message as the timeout limit is less and the query should end without fetching the results.
    Kindly let me know how to resolve the above issues, any pointers will be helpful.
    Thanks in advance.

  • How to implement autocomplete?

    Hello,
    I have a String array with strings in non-alphabethical order.
    I would like to implement autocomplete (just like in IE address line) on a JTextField.
    I guess I'll need to put some listener on textfield, but which? And how to handle array - sort it before use? Any other possibilities?

    Well, first you'd need something to compare the String being typed in to, so that you know what the user might be trying to type. Then, I guess you'd need a KeyListener on text field, so each time a key is pressed, you run a search and return all the possible Strings that could match it.
    I'd be a little lost as to how to implement the drop-down list like IE (or Windows in general) has to handle auto-complete. The other way to handle it would be to have the word fill itself into the textbox as you type, leaving the guessed part highlighted so you can continue to type, and continue to get suggestions. This approach seems a bit easier, and could be handled fairly easily.

  • How to implement content caching for jsp page ?

    Hello everyone,
    I am reading an article <Servlets and Jsp Best Practice>,at
    http://developer.java.sun.com/developer/technicalArticles/javaserverpages/servlets_jsp/#author, on one section it is saying :
    "Cache content: You should never dynamically regenerate content that doesn't
    change between requests. You can cache content on the client-side, proxy-
    side,or server-side. "
    Now I am working on a project. For every user, some of the content servlet generated will be the same for at least a week . I am thinking if I implement caching for these jsp pages, that would increase performace a lot.
    But I have no idea how to implement it either client-side or server-side, can someone give me a hint ?
    Thanks,
    Rachel

    You mean actually you are caching the response stream
    and the key to distinguish between different response
    streams are made of user's different request
    parameters. And the filter's function is to intercept
    the request to see if this request parameter's
    combination already exists in the Hashmap,then either
    use the cached response or forward to
    servlet.....really interesting...Do I get it right ?Yes that's it in a nutshell.
    >
    Then how do you build those response streams in
    advance ? You did it manually or have some mechanism
    to build it automatically ?
    The data gets cached the first time somebody visits the page.
    Find some examples on Filters, and take a look at the HttpServletResponseWrapper class. You need to cache response headers as well as the body. Another pitfall that you might run into is handling an If-modified-since header on the request. Don't cache the results of those requests.

  • How to implement metadata keyword tags

    Can someone please advise me on how to implement meta keyword tag <meta name="keyword" content="..."> for individual community page? We have a set of keywords for each community page. I know we can just add the line above to base page layout if they are common keywords to all the community page but not sure whats the best way to add unique set of meta keyword tags to individual community page? FYI - We are using UCM for managing content for our site.

    I always did this using a property on the page object.
    1. Create a new property called "meta-keywords" and associate it to the community pages object through the global object property mapper utility.
    2. Edit your community page and add any keywords you desire.
    3. Write a custom tag for said property that takes a uuid as input (this way you can migrate and the tag remains the same.
    4. same idea works for any meta tag.
    Note: you are limited to 255 characters this way.
    Or you can probably code some kind of tag that reads from UCM as well, but i always did it the above way.
    Here is a tag example:
    public class MetaPropertyCurrentPage extends ATag {
         private OpenLogger log = OpenLogService.GetLogger(
                   OpenLogService.GetComponent(PTDebugHelpers.COMPONENT_PORTAL_COMMON),
                   "customizations.tag.standard.MetaPropertyCurrentPage");
         public static final RequiredTagAttribute UUID;
         public static final ITagMetaData TAG;
         static {
              TAG = new TagMetaData("currpageproperty",
                        "Displays the value of the property in the current page from the uuid.");
         UUID = new RequiredTagAttribute("uuid", "The UUID for the property you want to open.",
    AttributeType.STRING);
         @Override
         public ATag Create() {
              return new MetaPropertyCurrentPage();
         @Override
         public HTMLElement DisplayTag() {
              log.Info("Entering meta lookup");
              String objectid;
              String classid;
              HTMLElement result = new HTMLElementCollection();
              IEnvironment env = GetEnvironment();
              AActivitySpace owner = TaskAPIUICommon.GetEnvTypeObject(env);
              //get pageid
              int pageid = TaskAPIUICommunity.GetCurrentCommunityPageID(owner);
              //check if not a community page
              if (!TaskAPIUICommunity.IsCurrentPageCommunityPage(owner))
                   return result;
              //convert to objectid
              try
                   Object[] objectAndClassId = ((IPTMigrationManager)(((IPTSession)GetEnvironment()
                   .GetUserSession()).OpenGlobalObject(PT_GLOBALOBJECTS.PT_GLOBAL_MIGRATION_MANAGER,
                   false))).UUIDToObjectID(GetTagAttributeAsString(UUID));
                   objectid = objectAndClassId[PT_MIGRATION_OBJECT_COLS.PT_MOC_OBJECTID].toString();
                   log.Info( "found objectid" + objectid);
                   classid = objectAndClassId[PT_MIGRATION_OBJECT_COLS.PT_MOC_CLASSID].toString();
                   //check to make sure its a property
                   if (Integer.parseInt(classid) != PT_CLASSIDS.PT_PROPERTY_ID)
                        return new HTMLComment("UUID does not belong to a property");
              catch (Exception e)
                   log.Error(e, "error getting the objectid from the UUID.");
                   return null;
              //now get the property from it
              IPTSession session = (IPTSession)GetEnvironment().GetUserSession();
              IPTObjectManager objMgr = session.GetPages();
              IPTPage page = (IPTPage)objMgr.Open(pageid, false);
              log.Info("Page name: " + page.GetName());
              IPTQueryResult qresult = page.GetObjectProperties().GetSinglePropertyData(Integer.parseInt(objectid), PT_PROPIDS.PT_PROPID_PROP_VALUE);
              if (qresult.Data() != null)
                   IPTObjectManager objMgr2 = session.GetProperties();
                   IPTProperty prop = (IPTProperty)objMgr2.Open(Integer.parseInt(objectid), false);
                   String propName = prop.GetName();
                   log.Info("Property name is: " + propName);
                   String value = (String) qresult.Data()[1][0];
                   if (lang.equalsIgnoreCase(propLocale) && value != null && !value.equalsIgnoreCase(""))
                        result.AddInnerHTMLString("<meta name=\"" + propName + "\" content=\"" + value + "\" />");
              else
                   log.Info("Property Value not found.");
              return result;

  • How to implement Master-Detail Search in TopLink without using DataControl

    Hi,
    I am using TopLink and EJB in our requirement. But we are not creating any data controls. Without data controls how to implement master detail search using TopLink and EJB. I did search for a single table. It is working fine. The way i implented is as follows.
    1) Taking search parameter from UI and passing it to A delegator class's method.
    2) Delegator class's method calls the EJB's NamedQuery which i already created using expression builder.
    3) EJB executes the NamedQuery with the parameter we are passing. And it returns the results back to UI.
    But as i am new to TopLink, can anyone tell me the procedure to implement Master - Detail search. Here we need to search based on Master table's column.
    Waiting for the replies regarding this.
    Thanks & Regards,
    Suresh Kethireddy

    Hi,
    I did it successfully. Following is the code.
    Session session = getSessionFactory().acquireSession();
    UnitOfWork uow = session.acquireUnitOfWork();
    ReadAllQuery raq = new ReadAllQuery();
    Dept d = new Dept();
    d.setLoc(loc);
    raq.setExampleObject(d);
    List<Dept> res=(List<Dept>)uow.executeQuery(raq);
    for(int i=0; i<res.size();i++){
    System.out.println("Dept DeptNo ---"+res.get(i).getDeptno());
    System.out.println("Dept DeptName ---"+res.get(i).getDname());
    System.out.println("Dept Location ---"+res.get(i).getLoc());
    List<Emp> eRes=res.get(i).getEmpCollection();
    for(int j=0; j<eRes.size();j++){
    System.out.println(" Emp No ---"+eRes.get(j).getEmpno());
    System.out.println(" Emp Name ---"+eRes.get(j).getEname());
    System.out.println("Emp HireDate ---"+eRes.get(j).getHiredate());
    System.out.println(" Emp Job ---"+eRes.get(j).getJob());
    System.out.println(" Emp Mgr ---"+eRes.get(j).getMgr());
    System.out.println(" Emp Sal ---"+eRes.get(j).getSal());
    But now my question is, i want to search by providing Dept param as well Emp(Which is child table) param also. Is it possible?
    I tried in 2 ways like this.
    1) Emp emp = new Emp();
    emp.setEname(eName);
    dept.addEmp(emp);
    raq.setExampleObject(dept);
    2) Emp e = new Emp();
    e.setEname("ADAMS");
    List<Emp> list = new ArrayList();
    list.add(e);
    d.setEmpCollection(list);
    raq.setExampleObject(d);
    But in both cases i failed to search based on the values i am passing to Emp.
    Is there any other way to achieve my requirement?
    Any help on this is great.

  • E-Recruiting - how to implement questionnaires in candidate profile?

    Hello experts,
    has anyone experience in how to implement questionnaires into the container sequences of the candidate profile (for internal as well as external candidates)?
    I think, I know all the necessary tables (T77RCF_CS_ID, -_SEQ and -_ITEM), have also studied the IMG, but simply don´t get it.
    Thanks in advance.
    Greetings,
    Florian

    Hello,
    as I said you can just solve it out of the front end within the registration workflow, or the candidate status change workflow.
    So it is just possible to do this via a correspondence activity and not via the standard front end.
    From the correspondence you can jump back to a front end application. But it is not possible to integrate it into a startpage.
    If the candidate filled out a questionnaire (trm activity), then  you can search on those questionnaires and its answers via the talent pool search. Prerequisite is, that the questionnaire is assigned to a trm activity (Assigned to NA).
    There is no possibility handling pool candidates as applications. You will always have problems looking at each pool candidate. The talent pool is just meant to be a pool of candidates you can search on.

Maybe you are looking for
