Passing data to a method

I would like to pass a string
String st = "word" [\code]
from a void method to another
code] void useful(String a) [\code]
What kind of statement shall I use in the first method?
Thanks for any help.

Well, there is a "New to Java" forum.
But if you're asking questions on this level...you need an introduction to computer programming textbook. Every language is about the same with respect to your question.
Please don't feel discouraged from asking questions, but at this point it's going to be a lot slower to ask questions like that on forums than it would be just to work through a good introductory text.

Calling a new browser window with WD Abap and passing data via POST

Hi there,
does anybody know whether passing data via POST method is possible when opening a new browser window from within a Web Dynpro Component? In my case I use method IF_WD_WINDOW_MANAGER->CREATE_EXTERNAL_WINDOW for opening a new browser window. Now I want to pass a big amount of data which is only possible via POST method. How can I achieve that or is it not considered inside the Web Dynpro Framework?
Kind regards,

Best method for passing data between nested components

I have a fairly good sized Flex application (if it was
stuffed all into one file--which it used to be--it would be about
3-4k lines of code). I have since started breaking it up into
components and abstracting logic to make it easier to write,
manage, and develop.
The biggest thing that I'm running into is figuring out a way
to pass data between components. Now, I know how to write and use
custom events, so that you dispatch events up the chain of
components, but it seems like that only works one way (bottom-up).
I also know how to make public variables/functions inside the
component and then the caller can just assign that variable or call
that function.
Let's say that I have the following chain of components:
Component A
--Component B
-- -- Component C
-- -- -- Component D
What is the best way to pass data between A and D (in both
directions)?
If I use an event to pass from D to A, it seems as though I
have to write event code in each of the components and do the
bubbling up manually. What I'm really stuck on though, is how to
get data from A to D.
I have a remote object in Component A that goes out and gets
some data from the server, and most all of the other components all
rely on whatever was returned -- so what is the best way to be able
to "share" data between all components? I don't want to have to
pass a variable through B and C just so that D can get it, but I
also don't want to make D go and request the information itself. B
and C might not need the data, so it seems stupid to have to make
it be aware of it.
Any ideas? I hope that my explanation is clear enough...
Thanks.

Peter (or anyone else)...
To take this example to the next (albeit parallel) level, how
would you go about creating a class that will let you just
capture/dispatch local data changes? Following along my original
example (Components A-D),let's say that we have this component
architecture:
Component A
--Component B
-- -- Component C
-- -- -- Component D
-- -- Component E
-- -- Comonnent F
How would we go about creating a dispatch scheme for getting
data between Component C and E/F? Maybe in Component C the user
picks a username from a combo box. That selection will drive some
changes in Component E (like triggering a new screen to appear
based on the user). There are no remote methods at play with this
example, just a simple update of a username that's all contained
within the Flex app.
I tried mimicking the technique that we used for the
RemoteObject methods, but things are a bit different this time
around because we're not making a trip to the server. I just want
to be able to register Component E to listen for an event that
would indicate that some data has changed.
Now, once again, I know that I can bubble that information up
to A and then back down to E, but that's sloppy... There has to be
a similar approach to broadcasting events across the entire
application, right?
Here's what I started to come up with so far:
[Event(name="selectUsername", type="CustomEvent")]
public class LocalData extends EventDispatcher
private static var _self:LocalData;
// Constructor
public function LocalData() {
// ?? does anything go here ??
// Returns the singleton instance of this class.
public static function getInstance():LocalData {
if( _self == null ) {
_self = new LocalData();
return _self;
// public method that can be called to dispatch the event.
public static function selectUsername(userObj:Object):void {
dispatchEvent(new CustomEvent(userObj, "selectUsername"));
Then, in the component that wants to dispatch the event, we
do this:
LocalData.selectUsername([some object]);
And in the component that wants to listen for the event:
LocalData.getInstance().addEventListener("selectUsername",
selectUsername_Result);
public function selectUsername_Result(e:CustomEvent):void {
// handle results here
The problem with this is that when I go to compile it, it
doesn't like my use of "dispatchEvent" inside that public static
method. Tells me, "Call to possibly undefined method
"dispatchEvent". Huh? Why would it be undefined?
Does it make sense with where I'm going?
Any help is greatly appreciated.
Thanks!

Pass current row data from table and pass it to a method in AM

Hi All,
I have a table with row selection enabled. Also for each row I have a select image which on selection should pass the data from one of the columns of the current row selected to a method in AM.
Can anybody let me know on "How on selection of the image in any row, can I pass the column data to the method in AM?".
Thanks,
Vijay

Hi,
the most easiest and straight forward approach is
- Ckick the "Binding" tab at the bottom of the Visual Editor
- In the Bindings section click teh green plus icon and choose Generic Bindings | Attribute Value
- point the iterator selection to the iterator used by the table
- choose the column's attribute name from the list of attributes
- Create a method on the ApplicatioNModule IMPL class (should take single argument)
- expose it as a client interfaces so it shows in the Data Controls panel
- In the "Binding" tab, create a method binding for this exposed method
- point the method binding argument to #{bindings.column-attribute-name.inptValue}
So whenever you need to pass the value on to the AM, you just call the method binding
OperationBinding oper = (OperationBinding) bindings.get("name of method");
oper.execute();

Passing Data to a Paint Method

Total newbie here just learning the basics of Java on my own. Working a little application that will display a filled polygon which shows the correct heading of ship based on previously input Ship Heading, length and width. I have the application working fine to generate the 5 points, and then it will display correctly when I enter the points in the paint method by hand. Thing is I want to have the coords passed to the paint method. and am having some trouble doing this. All the examples I have seen show the points to be displayed already being declared in the paint method. Here is the Paint Method I have come up with based on examples I have seen. Still pretty new and trying to read through the APIs and other books, but haven't broken the code on understanding them.

What are the methods available for passing data between Labview 6.0 VI and another custom windows program

The big picture is that I'm trying to use labview to interface to a DSP board.
I already have a small windows application "app" which communicates with the dsp. Now I want Labview to grab data from the "app" and plot/analyze ... etc.
I'm a novice at this 'interprocess communication stuff", what can I use to pass data back and forth between between the "app" and LV?
use ActiveX, DMA, streams, etc.?
In a crude sense I could just have the "app" write the data to a file and then have LV read the file. (can two applications read the file at the same time?), but
this seems very slow and clumsy. I'd rather have a RAM based FIFO which both could access.
Thanks!

Details:
Pentium120 Windows 95 Host

It depends on what 'interprocess communication' your "app" program has available.
I regulary use DDE to control a PLL App which controls our PLL via the LPT Port. This is only a write process, but works very easily. The read is equaly easy. You need to know the various "keywords" like service, topic and instruction which the "app" will respond to.
Generaly I found ActieX to be more extensive, meaning its probably going to take longer and more steps to achive similar simple results.
The file does not seem to be the best way.
Hope that helps a bit.

Passing data b/w applet and apache server

Hi all,
I have an application that runs in the JApplet.I have to pass data b/w server and applet.The
datas are brought from the server using php to the browser and passed to applet using param
tags.
1.Is it possible to set value for the param tag from applet?
2.How to retrieve data from the param tag to the applet in the form of an array.
In the getParameter it is required to specify the param name.
Is it possible to retrieve data from param tag similar to that of getting data from command
line arguments array.

Hi all,

datas are brought from the server using php to the
browser and passed to applet using param
tags.
1.Is it possible to set value for the param tag from
applet?Why do you ever want to do it? It sounds like setting arguments passed to a program's main method from command line after the main method has been invoked. It is possible though to dynamically set any values for any applet params using php before the applet gets loaded to the browser window as you generate an html file on the server side.
2.How to retrieve data from the param tag to the
applet in the form of an array.
In the getParameter it is required to specify the
param name.
Is it possible to retrieve data from param tag similar
to that of getting data from command
line arguments array.You can use some naming/numbering convention for your params. For example settings1, settings2 ... Then you can loop in your code retrieving the values like getParameter("settings" + i) checking to see that it is not null or empty.
However, if you don't want to reload the applet (together with the page) just to get some new data from the server, you can establish a tcp/ip connection as elchaschab recommended.
Cheers!

Passing data from one frame to another frame

hello all, i am having a problem with passing data from one frame from another. I have a main frame when you click on connect button it display the second frame(class) that has 2 text fields and 2 buttons. When i click on connect it check if the data is correct. If the data is correct i want that frame to close and pass the data back to main frame. How can i do that.
thank you

hello all, i am having a problem with passing data
from one frame from another. I have a main frame when
you click on connect button it display the second
frame(class) that has 2 text fields and 2 buttons.
When i click on connect it check if the data is
correct. If the data is correct i want that frame to
close and pass the data back to main frame. How can
i do that.
thank you
the original problem sounded like an ideal opportunity to use Modal Dialog. if you want one frame to display another to get user input then you need to stop the method in the main frame from executing until you recieve a valid input.
you can use your own class and keep all of the components that you have in the connect frame but you would have to extend JDialog instead of JFrame.
there is a way around it!
if you must use JFrame for both, then you need to have access to the main frame in the connect frame, maybe pass the pointer to the constructor??
anyway, when the connect frame is done with its duties, you have to use the pointer to call another method in the main frame that will continue the process. otherwise main frame doesn't know when connect frame is done and by that time, the method in main frame that instantiated the connect frame has long since died.
also, it allows things to happen in the other window that you may not want to happen until the connect frame is done
typically users of software start clicking around on things and you could have three or four connect frames going at the same time
it's really best to use a Modal Dialog, it really can look just like a JFrame!!!!!!!!!!!!!!

Problem in passing data from 1 screen to another using BBP_DOC_CHANGE_BADI.

Hi Experts,
i am new to the SRM, i am facing problem in passing data from one screen to another.
my requirement is that when we select one shopping cart and press the PROPOSE SOURCES OF SUPPLY button, we will fetch all the contracts that are attached to the shopping cart.
we have implemented a BADI implementation of BBP_SOS_BADI (method BBP_SOS_CHECK) for passing some changed values to the contracts of the shopping cart into the popup screen that is displayed when we press PROPOSE SOURCES OF SUPPLY button and when we select any contract and press ASSIGN ONLY button in the popup screen the badi BBP_DOC_CHANGE_BADI is triggered.
i have implemented another BADI implementation of BBP_DOC_CHANGE_BADI for fetching the selected contract and pass the values to another screen, but the problem is that when we select one contract and press the assign only button we are fetching the wrong contract number ( that is in the BADI method BB_SC_CHANGE parameter IT_ITEM we are fetching the wrong contract), if we again do the same procedure for the second time we are getting the correct contract.
i am unable to understand why we are getting the wrong contract in the first time( that is we are getting contract other than the selected one).
as per my understanding i think when we are passing data to the popup screen using BBP_DOC_CHANGE_BADI we are not updating the shopping cart with the changed data.
can anyone tell me how we can update the SHOPPING CART with the changed contracts data, i have used BBP_PD_SC_UPDATE, BBP_PD_SC_SAVE and other shopping cart FM but nothing is happening.
Thanks
Tanveer

Hello,
What version of SRM are you on? Have you check for OSS Notes? I have had trouble with BBP_DOC_CHANGE_BADI but it was because of other issues. The BADI works pretty well and it is called almost every time something happens to the shopping cart.
I have noticed that sometimes that values are not changed til the second calling of the BADI. I have yet understand why but I think it has to do with prompt processing. Usually, we train our requisitioners to click the 'Check' button to flush things out.
I don't know if I was helpful.... another thought.... could there be an error caught by BBP_DOC_CHECK_BADI that is preventing change in BBP_DOC_CHANGE_BADI?

Passing data from one bsp application to another

Hi,
I have few queries that most of you would have done in ur projects:
1. I want to pass data from one bsp application to another:
eg based upon selected row of table view which populates material no and descriprion to another application which open the entire material master data.
Now, i have both the pages in diff bsp applications in place but unable to pass the selected material code to the second bsp application.
Had it been two different pages of same application I was able to achieve it with set parameter()
2. To stop the application from reprcessing the data:
eg: Suppose I have a bsp page where user fill details of a customer and on submitinng the details a customer is created in background and the entire page is disabled by my code. Even now if the user press refresh (F5) button then another customer gets created in the background. So basically i want to avoid the reprocess of the onSubmit event
Few lines of sample code would be very helpful.

What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,
LaVIEWan
Solved!
Go to Solution.

Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

Passing data from one screen to another(web-dynpro) in SRM sourcing cockpit

HI Experts,
i am facing problem in passing data from one web-dynpro screen and assigning the data it to another web-dynpro screen.
my requirement is that when ever user selects a contract in PROPOSE SOURCES OF SUPPLY screen popup and press only assign only button, the data of the contract should be copied to the shopping cart.
i have already used the BADI BBP_DOC_CHANGE_BADI, but unfortunately it was not working.
so i tried to use the context, element and other web-dynpro fields to pass the data, i am able to pass the data from the popup to the second screen and able to assign it.
but when ever i deselect the shoppping cart which has been assigned with the data of the popup and select another shopping cart the data of the above shopping cart is cgetting changed.
i am unable to figure out the exact reason why this is happeing.i have written code in the ASSIGN ONLY button method to fetch the popup data and in the WDONMODIFYVIEW method of the second screen to assign the popup data to the shopping cart.
i have tried to bind the elements using the BIND_TABLE, BIND_STRUCTURE, BIND_ELEMENT, BIND_ELEMENTS methods, but nothing is working.
can anyone suggest me where i am making mistake and try to solve the issue.
Thanks

How to specify a date in a method signature

How do I specify a date as a method parameter of a bean that will be used to generate
a SOAP service? If I specify java.util.Date, I get NullPointerExceptions, perhaps
because the internal structure of Date is not compatible with SOAP supported types.

Hi,
There are few simple ways for date validation as follow,
1.If you would like to handle it in XI only, then in message mapping you could verify about it with the help of generating smart exception.
For e.g in mapping there is one Date conversion API i.e. somthing DateTransformation It converts the incoming date format to required format. Here give the date format i.e expected from Sender File.
If in case the format miss-matched then it will create the exception.
You could handle this exception with the use of [Alert notification|http://help.sap.com/saphelp_nw04/helpdata/en/2c/abb2e7ff6311d194c000a0c93033f7/frameset.htm] and could be even able to notify to sender system about it.
2. The another solution is easy for SAP synchornous communication --If you are passing the file data to SAP, then you could use below function modules to verify date format in receiver RFC/BAPI or inbound IDOC program. If the sy-subrc is not 0 then don't process further.
CONVERT_DATE_FORMAT
ISU_DATE_FORMAT_CHECK

I has successful use the RequestDispatcher.forward(request, response) to post data from servletA to servletB. whereas i faced a trouble to post data back from servletB to servletA, which i unable put the queried result into request obj before post it back to servletA.
Any genius recommendation about this? or Any method composed data to send via post method?

Here's a quick rundown that might help:
Use request.setAttribute() to put an item in request scope in a servlet before dispatching to another servlet or JSP.
Use <useBean> tag in a JSP to read the data on the JSP that the servlet put in request scope.
Alternatively, you can use request.getAttribute(), but the useBean is preferred.
Use request.getParameter() in a servlet to read data that the <form> tag on the JSP page put in request scope.
Use request.setAttribute() and request.getAttribute() to get send/get data between servlets (it could be request.getParameter(), but I dont think so).
There is a RequestDispatcher.forward() and a RequestDispatcher.include(). I'm not sure what the differences are (you'll have to research it.
In MVC, I have a single servlet for the controller (receive all url's, and dispatch to the appropriate JSP). I dont hava a separate servlet for the model. Instead, I instansiate a business object on the servlet, pass data to it, and let it do the calcuations. Then I have it return the data to the servlet which puts it in request scope for the JSP page when I dispatch to it. My MVC usuallyconsists of:
JSP -presentation layer
servlet - control layer
business logic layer
database layer (DAO).
Each layer does not contain the functionality of one of the other layers (clean separation of concerns).
Last note: Whereas you can use a servlet for the controller, a framework such as Spring or Struts is often used instead.
