How to pass an object as a parameter

how do you pass an object as a parameter? (what type should it be ?)

Well you can use a [url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html]String
Or you can take a [url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Double.html]Double
And you can pass [url http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Event.html]Events
and get yourself in trouble
and you can use a [url http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Frame.html]Frame
or maybe take a [url http://java.sun.com/j2se/1.4.2/docs/api/java/util/List.html]List
but some will use [url http://java.sun.com/j2se/1.4.2/docs/api/java/util/Collection.html]Collection
depends you your direction
so if you need to know
if you should use a [url http://java.sun.com/j2se/1.4.2/docs/api/java/util/Map.html]Map
then this is what to do
just browse the [url http://java.sun.com/j2se/1.4.2/docs/api/]API

  • How to pass class object  as in parameter in call to pl/sql procedure ?

    hi,
    i have to call pl/sql proecedure through java. In pl/sql procedure as "In" parameter i have created "user defined record type" and i am passing class object as "In" parameter in call to pl/sql procedure. but it is giving error.
    so, anyone can please tell me how i can pass class object as "In" parameter in call to pl/sql procedure ?
    its urgent ...
    pls help me...

    I want to pass a cursor to a procedure as IN parameter.You can use the PL/SQL type called sys_refcursor - and open a ref cursor and pass that to the procedure as input parameter.
    Note that the SQL projection of the cursor is unknown at compilation time - and thus cannot be checked. As this checking only happens at run-time, you may get errors attempting to fetch columns from the ref cursor that does not exist in its projection.
    You also need to ask yourself whether this approach is a logical and robust one - it usually is not. The typical cursor processing template in PL/SQL looks as follows:
    begin
      open cursorVariable;
      loop
        fetch cursorVariable bulk collect into bufferVariable limit MAX_ROWS_FETCH;
        for i in 1..bufferVariable.Count
        loop
          MyProcedure( buffer(i) );   --// <-- Pass a row structure to your procedure and not a cursor
        end loop;
        ..etc..
        exit when cursorVariable%not_found;
      end loop;
      close cursorVariable;
    end;

  • How to pass an object from jsp to other jsp using SendRedirect

    How to pass an object from one jsp to the other jsp using ssendRedirect with out using the session
    I am having 2 jsps
    x.jsp and y.jsp
    From x.jsp using sendRedirect iam going to y.jsp
    From x.jsp i have pass an object to the y.jsp
    Is it possible without putting the object in session
    Is it possible using EncodeUrl
    Please help me Its Urgent

    Is it possible without putting the object in sessionAnything is possible. Would you accept that it is very difficult?
    When you send a redirect, it tells the browser to send a new request for the target page. That means any request parameters/attributes are lost.
    Is it possible using EncodeUrl response.encodeURL() puts the session id into a url if the browser does not support cookies. It is purely for retaining the session.
    There are two ways that you can communicate across a sendRedirect.
    1 - use the session
    2 - pass a parameter in the url.
    parameters are string based, so passing objects is almost out of the question.
    Potentially you could serialize your object, encode it in base64 (so it is composed completely as characters) and pass it as a parameter to the other page, where you retrieve it, unencode it, and then load the serialized object.
    Or you can just use the session.

  • How to pass a Class as a parameter of a method?

    I have a method like below. Inside this method I need to create a variable that his type is the type of the class I have passed as a method's parameter.
    For example, if I call the method like this "Meth1(ClassPerson);" insed the method I need to declare a  variable of class "ClassPerson", but if I call like "Meth1(ClassCity);" I need the same variable to be declared as a ClassCity.
    public function Meth1( /*I dont know what to put here*/   ):void{
         /*I dont know what to put here to declare my variable*/
         /*here
         comes
         more
         code
         using
         the
         variable*/
    I tried as below but dont worked:
    public function Meth1( classtype:Class):void{
         var var1:classtype = new classtype();
    Can someone help me?

    evyatarBH, after declare the variable like you said an error occurs when I try to access some property of the variable. I receive a mesage telling that this property dont exists.
    public function Meth1( classtype:Class ):void{
         var var1:* = new ClassFactory(classe);
         //when I try to do something like the line below the error appear
         inputtext1.text = var1.fieldname;
    rashare, I can't do this because I can't declare the object before the method is called. I must inform to the method only which class I will use, but the object must be created only inside the method.

    type of parameter is read-only and not accessible in parent report.
    This varies from a Hidden Parameter, which the user is not prompted to provide, but can still be configured through the URL to the report server.
    So no matter you access the report through report manager, URL or Report Viewer. The passing value to the internal parameter will not work.
    As you have mentioned that I will also suggest you use the hidden parameter instead.
    More details information in this blog for your reference:
    SSRS – Understanding Report Parameter Visibility
    How to pass value to  hide parameter is the same as that of the visible parameter, similar thread for your reference:
    Passing the value in action property of a text box
    If you still have any problem, please feel free to ask.

  • HOW TO PASS SELECT-OPTIONS AS IMPORT PARAMETER TO A CLASS

    Hi experts,how to pass select options value as a export parameters to a zclass.
    can  give me some idea.
    Thanks
    sai

    As Sachin already said, selection options are stored in an internal table. You can reconstruct the table type without the corresponding input fields using the type addition RANGE OF.
    So - assuming you have the following in your program:
    DATA: wa TYPE sflight.
            SELECT-OPTIONS so_car FOR sflight-carrid.
    you can create a publically-visible type in your class using direct type entry and the code
    TYPES: my_selectoption TYPE RANGE OF sflight-carrid.
    and use this to define the importing parameter of the method.
    The only other thing you have to remember is that select-options generates an internal table with header line. Thereore, to pass the table to the method, you would use (in the above example) so_car[], and not just the name of the select-option.
    Hope this helps.
    Regards
    Jon.

  • How to pass value to select-option parameter using SET PARAMETER Command

    Hi,
        Am passing values to selection-screen fields in report RV13A004 ( used in VK11, VK12 and VK13). using below statement but material number is select-option in this report. am able to pass  MATERIAL FROM using SET PARAMETER ID, can i know how to pass values MATERIAL TO range in select-options fields using SET PARAMETER Command ??
    Passing values to parameter id
    set parameter id 'VKS' field kschl.
    set parameter id 'VKO' field vkorg.
    set parameter id 'VTW' field vtweg.
    set parameter id 'KDA' field erdat.
    set parameter id 'MAT' field matnr_from.
    Change condition price.
    call transaction 'VK12' and skip first screen.
    Thanks in advance.
    Regards,
    Balamurugan.

    Hi,
    instead of using set parameters and dden call transaction use this..........
    submit RV13A004  WITH SELECTION-TABLE rspar
    Effect
    If you specify this addition, parameters and selection criteria on the selection screen are supplied from an internal table rspar. You must specify an internal table with the row type RSPARAMS for rspar. The structured data type RSPARAMS is defined in the ABAP Dictionary and has the following components, all of which are data type CHAR:
    SELNAME (length 8),
    KIND (length 1),
    SIGN (length 1),
    OPTION (length 2),
    LOW (length 45),
    HIGH (length 45).
    To supply parameters and selection criteria for the selection screen with specific values, the lines in the internal table rspar must contain the following values:
    SELNAME must contain the name of a parameter or selection criterion for the selection screen in block capitals
    KIND must contain the type of selection screen component (P for parameters, S for selection criteria)
    SIGN, OPTION, LOW, and HIGH must contain the values specified for the selection table columns that have the same names as the selection criteria; in the case of parameters, the value must be specified in LOW and all other components are ignored.
    If the name of a selection criterion is repeated in rspar, this defines a selection table containing several lines and passes it on to the selection criterion. If parameter names occur several times, the last value is passed on to the parameter.
    The contents of the parameters or selection tables for the current program can be entered in the table by the function module RS_REFRESH_FROM_SELECTOPTIONS.
    Notes
    In contrast to selection tables, the data types of the components LOW and HIGH in table rspar are always of type CHAR and are converted to the type of the parameter or selection criterion during transfer, if necessary.
    When entering values, you must ensure that these are entered in the internal format of the ABAP values, and not in the output format of the screen display.
    Cheers
    Will.

  • How to pass JSON object for a PUT operation of restful

    Hi,
    I am trying to proxy restful call through an OSB proxy and I would like to know how I can pass json object via OSB proxy to an external rest service for a PUT operation? I am using Oracle 11g.
    I have created a business service, that point to the external rest service and created a proxy service that route to the business service. I thought it automatically takes the JSON, which is the data need to be send to the rest service, but didn't work, I get 405 error in the osb access log. is that how it works, or there is something else I need to do? if so, can you please help and tell me how?
    appreciate any kind of help.
    thanks
    Marwa.

    Hi Anju,
    Most of the example I see is dealing with data being pass either as query-string or html form. We are passing JSON object from the UI and rest services are configured to take JSON. therefore, in the PUT and POST data are passed either as an attachment or part of the request object. Do you know or have an example how to do it? I don't need to any kind of transformation of data because I need JSON on both end and I am trying to use the OSB proxy in between my UI and rest services to take advantage of monitoring capability of the OSB.
    appreciate any help, my deadline is getting close and I kind stuck.
    Thanks
    M.

  • How to passing multiple values for a parameter of discoverer(url parameters

    Hi All,
    I am trying to pass multiple values for a parameter of disco report. I am trying to include my url for discoverer viewer report. the values has the following
    'jeff,mark'
    'sfophiee,angela'
    Thanks and Regards
    Venkat

    Hello Venkat,
    I know there are some problems with 10.1.2.0.2, maybe if you haven't done yet you can try with 10.1.2.2, assuming this version should be working for multiple parameter values :
    OracleAS Discoverer 10.1.2.2 is installed with the following patch :
    Patch 4960210 PLACEHOLDER BUG FOR AS/DS 10G R2 PATCH SET 2 10.1.2.2
    So, once installed you can try adding your parameter as param_<parameter_name>='sfophiee,angela'
    Hope this helps, otherwise feel free to log a Service Request to Support.
    Best Regards,
