How to get ep authority in jsp page

Hi all:
I want to create a j2ee project and some jsp pages to deploy to EP server.
My question is how to get user name or user authority in jsp page.
Is there any APIs to use or something else.
Thanks in advance.
Allen

Hai ,
I Think  This will help ful for u check it ,
File=new FileLog("f:/WebServiceTrace/trace2.%g.log", 800000, 10,                                        new  TraceFormatter());
The above code specifies the path for your log file.
Then add this file as a log location and then log the traces. For this you can use the following code like:
Location location=Location.getLocation(className);
          location.addLog(file);
          location.setEffectiveSeverity(Severity.ALL);
          location.entering(methodName);
To Create j2ee apllication
In path new-j2ee-jsp to create JSP's can only be used for J2EE applications.
So as you are using this in Portal Application, this does not work.
You can test this bahavior by creating a new Web Application (New-Project-J2EE-Web Module Project)
In this Web Module Project, try creating JSP, this will work.
So dont use new-j2ee-jsp to create JSP in Portal Application instead use New-File and name the file as jsp.

  • How to get Tree structure in JSP page?

    Hi,
    I would like get data from the database and display the data in tree structure with the check boxes at each nodes on a jsp page with out using any third party tools. how can i do that? Do i require any new tags to fulfill this requirement?
    can any one help me out by sending any example code?
    thanks in advance.
    Regards,

    Once you have the data in a list or something, can't you just use <c:forEach> and then output standard nested <ul> and <li> tags to give the tree structure.

  • How to get Parameters in a jsp page called by VB program via xmlHttp

    I have a VB programm sending a request using xmlHttp.
    xmlHttp.Open "POST", varTarget, True 'True means asynchronous
    xmlHttp.Send xmlSendStr
    This worked fine with ASP
    the crucial ASP code was:

         xml.load(request)
         VBData = cstr(xml.getElementsByTagName("value").item(0).firstChild.nodeValue)

    seems not to do the job.
    what do I have to do
    I am thankfully looking forward to you reply
    peter

    Hi,
    thanks for your reply!
    If I have the parameters in the URL and use the method GET it works all right.
    but I need the method to be POST. I suppose, I have the wrong way identifying the parameter name
    This is from VB
    varTarget = "http://localhost:9090/gm/getData" ' getData is my servlet
    xmlSendStr = "SQLStmt=SELECT TCPD_Cars.* From TCPD_Cars WHERE (((TCPD_Cars.CarIdent)=45));"
        xmlHttp.Open "POST", varTarget, True   'True means asynchronous
        xmlHttp.Send xmlSendStrthis is part of my Servlet

                   throws ServletException, IOException {
              response.setContentType("text/html");
              PrintWriter writer  = response.getWriter();
              String SQLStmt = request.getParameter("SQLStmt") ;
            //make the database query and get the returns
            writer.println(GetSQLData(SQLStmt));

  • How to Hightlight the Data in Jsp Page

    How to Hightlight the Data in Jsp Page,
    I am doing doing search page,based on values given search page those are sent to servlet,in servlet based on some conditions if particuler id i am getting then i am redirecting to Respective jsp page with highlight the data from database..
    Thanks in advance...

    "Highlighting data in JSP sounds strange".
    Without looking at your search specific algorithms I feel you are finally going to display a page (HTML content) to user which contains highlighted text. Highlighting is not directly related to server side language you use (JSP, ASP, PHP etc.). This is purely HTML and CSS. However, server side script (such as JSP) should generate HTML content for getting highlight effect.
    Following HTML shows highlighted text using background-color property on span element.
    <html>
      <head>
        <title></title>
        <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
      </head>
      <body>
          <p style="font-size:1.1em">This is a long paragraph which contains <span style="background-color: yellow;">highlighted text</span> and non highlighted text.</p>
      </body>

  • How to get rid of the Login page in Portal?

    Hi Guys,
    I have a newly developed intranet portal project for my company which does not need login no more. I hope you can help me how to get rid of the login page in portal which is I know in every application you create, there should be a login. Is this possible that I can just simply type in to the URL address bar my application then it will no longer ask for any logins? Please help! Many thanks!
    Russel

    Hi Russel,
    You can give public access to pages, applications etc. Users won't need to supply a username/password then, while you still can hide some of the pages to authorized people.
    Check the access tab for pages and the manage tab for applications.

    A lock object is a virtual link of several SAP tables which is used to synchronize simultaneous access by two users to the same set of data ( SAP lock concept).
    Locks are requested and released in the programming of online transactions by calling certain function modules which are automatically generated from the definition of the lock objects. These lock objects must be explicitly created in the ABAP Dictionary.
    <b>To set locks, you must perform the following steps:</b>
    1. You must define a lock object in the ABAP Dictionary. The name of the lock object should begin with E.
    2. The function modules for requesting and releasing locks which are created automatically when the lock object is activated must be linked to the programming of the relevant online transactions.
    <u><b>Reasons for Setting Locks</b></u>
    Suppose a travel agent want to book a flight. The customer wants to fly to a particular city with a certain airline on a certain day. The booking must only be possible if there are still free places on the flight. To avoid the possibility of overbooking, the database entry corresponding to the flight must be locked against access from other transactions. This ensures that one user can find out the number of free places, make the booking, and change the number of free places without the data being changed in the meantime by another transaction.
    <u><b>Lock Mechanisms in the Database System</b></u>
    The database system automatically sets database locks when it receives change statements (INSERT, UPDATE, MODIFY, DELETE) from a program. Database locks are physical locks on the database entries affected by these statements. You can only set a lock for an existing database entry, since the lock mechanism uses a lock flag in the entry. These flags are automatically deleted in each database commit. This means that database locks can never be set for longer than a single database LUW; in other words, a single dialog step in an R/3 application program.
    Physical locks in the database system are therefore insufficient for the requirements of an R/3 transaction. Locks in the R/3 System must remain set for the duration of a whole SAP LUW, that is, over several dialog steps. They must also be capable of being handled by different work processes and even different application servers. Consequently, each lock must apply on all servers in that R/3 System.
    <u><b>SAP Locks</b></u>
    To complement the SAP LUW concept, in which bundled database changes are made in a single database LUW, the R/3 System also contains a lock mechanism, fully independent of database locks, that allows you to set a lock that spans several dialog steps. These locks are known as SAP locks.
    The SAP lock concept is based on lock objects. Lock objects allow you to set an SAP lock for an entire application object. An application object consists of one or more entries in a database table, or entries from more than one database table that are linked using foreign key relationships.
    Before you can set an SAP lock in an ABAP program, you must first create a lock object in the ABAP Dictionary. A lock object definition contains the database tables and their key fields on the basis of which you want to set a lock. When you create a lock object, the system automatically generates two function modules with the names ENQUEUE_<lock object name> and DEQUEUE_<lock object name> . You can then set and release SAP locks in your ABAP program by calling these function modules in a CALL FUNCTION statement.
    <u><b>Lock Types</b></u>
    There are two types of lock in the R/3 System:
    <u><b>
    Shared lock</b></u>
    Shared locks (or read locks) allow you to prevent data from being changed while you are reading it. They prevent other programs from setting an exclusive lock (write lock) to change the object. It does not, however, prevent other programs from setting further read locks.
    <u><b>Exclusive lock</b></u>
    Exclusive locks (or write locks) allow you to prevent data from being changed while you are changing it yourself. An exclusive lock, as its name suggests, locks an application object for exclusive use by the program that sets it. No other program can then set either a shared lock or an exclusive lock for the same application object.
    example uses the lock object ESFLIGHT and its function modules ENQUEUE_ESFLIGHT and DEQUEUE_ESFLIGHT to lock and unlock the object.
    For more information about creating lock objects and the corresponding function modules, refer to the Lock objects section of the ABAP Dictionary documentation.
    The PAI processing for screen 100 in this transaction processes the user input and prepares for the requested action (Change or Display). If the user chooses Change, the program locks the relevant database object by calling the corresponding ENQUEUE function.
    MODULE USER_COMMAND_0100 INPUT.
      CASE OK_CODE.
        WHEN 'SHOW'....
        WHEN 'CHNG'.
    * <...Authority-check and other code...>
          CALL FUNCTION 'ENQUEUE_ESFLIGHT'
    EXPORTING
    MANDT = SY-MANDT
    CARRID = SPFLI-CARRID
    CONNID = SPFLI-CONNID
    EXCEPTIONS
    FOREIGN_LOCK = 1
    SYSTEM_FAILURE = 2
    OTHERS = 3.
    IF SY-SUBRC NE 0.
    MESSAGE ID SY-MSGID
    TYPE 'E'
    NUMBER SY-MSGNO
    WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
          ENDIF.
    The ENQUEUE function module can trigger the following exceptions:
    FOREIGN_LOCK determines whether a conflicting lock already exists. The system variable SY-MSGV1 contains the name of the user that owns the lock.
    The SYSTEM_FAILURE exception is triggered if the enqueue server is unable to set the lock for technical reasons.
    At the end of a transaction, the locks are released automatically. However, there are exceptions if you have called update routines within the transaction. You can release a lock explicitly by calling the corresponding DEQUEUE module. As the programmer, you must decide for yourself the point at which it makes most sense to release the locks (for example, to make the data available to other transactions).
    If you need to use the DEQUEUE function module call several times in a program, it makes good sense to write it in a subroutine, which you then call as required.
    The subroutine UNLOCK_FLIGHT calls the DEQUEUE function module for the lock object ESFLIGHT:
    FORM UNLOCK_FLIGHT.
         CALL FUNCTION 'DEQUEUE_ESFLIGHT'
              EXPORTING
                  MANDT     = SY-MANDT
                  CARRID    = SPFLI-CARRID
                  CONNID    = SPFLI-CONNID
              EXCEPTIONS
                  OTHERS    = 1.
         SET SCREEN 100.
    ENDFORM.
    You might use this for the BACK and EXIT functions in a PAI module for screen 200 in this example transaction. In the program, the system checks whether the user leaves the screen without having saved his or her changes. If so, the PROMPT_AND_SAVE routine sends a reminder, and gives the user the opportunity to save the changes. The flight can be unlocked by calling the UNLOCK_FLIGHT subroutine.
    MODULE USER_COMMAND_0200 INPUT.
      CASE OK_CODE.
        WHEN 'SAVE'....
        WHEN 'EXIT'.
          CLEAR OK_CODE.
          IF OLD_SPFLI NE SPFLI.
             PERFORM PROMPT_AND_SAVE.
          ENDIF.
          PERFORM UNLOCK_FLIGHT.
          LEAVE TO SCREEN 0.
        WHEN 'BACK'....

  • How to print new line in jsp page

    hi
    how to print new line in jsp page
    thanks

    \n - new line character is in java specific not HTML
    specific.Well, if the correct line separator sequence (by far not always \n) would be used, it does add a new line to the HTML output. Too bad that you don't want to see HTML but formatted text. The BR tag is a formatting element for the displayed text, not a line break in HTML. ;)
