Passing an object betweeen screens

Hi all,
I have a (main application) screen which displays a list of lets say product items so that user can select one and display it in another JFrame where he/she can edit info and save it. (this means sending it back to the previsous screen - that is the main screen)
Could anyone help me with this problem or give me some hints?
Thanks,

How are you trying to do this in general ?
You really need to be thinking along the lines of using the MVC (Model-View-Controller) approach that is built into Swing. In other words, build an object which simply encapsulates your data model (the list of items, in your case). Use the facilities offered by ListModel and ListSelectionModel. You then build two further separate objects which represent the two different views of your list (frames, panels, whatever they happen to be), and make these views 'listeners' to changes in the data. In that way, whenever changes occur to the actual data (whoever makes those changes), events get fired off to the views which are listening for those changes, and the views automagically update themselves in sync.
Sorry if I'm telling you something you already know. But if not, there's loads of Swing tutorials that tell you how to do this. E.g., take a look at:
http://java.sun.com/products/jfc/tsc/articles/architecture/
Hope I've understood correctly what you are trying to do.

Passing data to multiple screens through SAP webgui;

Hello, I'm working on building an application that requires me to pass data to multiple screens of a SAP transaction (IW31) through SAP webgui. The requirement is to enter the required information in the initial screen, "Header data" screen and in the "Object Data" screen. I'm using the below URL to launch the webgui:
http://myserver:8001/sap/bc/gui/sap/its/webgui/!?sap-client=800&sap-user=xxx&sap-password=yyy&sap-language=EN&transaction=iw31%20CAUFVD-EQUNR=20006001&AUFPAR-PM_AUFART=PM01&CAUFVD-GSBER=0001&OKCODE=/00&CAUFVD-ILART=103&~OKCODE==IOLU
This is failing with the following error message:
*Flow control: Entry SAPLCOIH, IOLU, A0, * , * , * is missing in T185*
I also noticed that if I stop at the point where I enter information in the initial screen and enter into the header data page using the below URL, it is working fine. The URL used is
http://myserver:8001/sap/bc/gui/sap/its/webgui/!?sap-client=800&sap-user=xxx&sap-password=yyy&sap-language=EN&transaction=iw31%20CAUFVD-EQUNR=20006001&AUFPAR-PM_AUFART=PM01&CAUFVD-GSBER=0001&OKCODE=/00
Can anyone please explain what is incorrect in the URL I'm passing?
Thanks in advance

Hi Vijay,
Thank you for your prompt response but I do not understand your answer or perhaps I am not makig myself clear.
Let me explain the current process:
1) Z program collects data and exports to Memory ID 'TEST01'.
2) Z program calls SAP program
3) SAP program calls User Exit '001' and data is read from Memory ID 'TEST01'.
4) SAP program collects some of the data and then executes SAP FM to continue processing.
5) SAP FM Executes User Exit for FM and data is read from Memory ID 'TEST01'.
6) SAP FM returns completed data back to SAP main program.
7) Z Program collects results from SAP program.
New process:
1) Z program collects data and exports to Memory ID 'TEST01'. Data now includes filter for CC.
2) Z program calls SAP program
3) SAP program calls User Exit '001' and data is read from Memory ID 'TEST01'.
4) SAP program collects some of the data and then executes SAP FM IN PARALLEL PROCESSING to continue processing.
5) SAP FM Executes User Exit for FM and an attempt to read data is read from Memory ID 'TEST01' fails.
6) SAP FM returns completed data back to SAP main program.
7) Z Program collects results from SAP program.
The dilemma is how to capture the proper CC filter in the FM exit when SAP is unable to read the data from memory ID 'TEST01'. I guess I can understand this since the tasks are executed in separate sessions and servers from the one that started the program since we are using a server group.
Perhaps I am missing something with respect to exporting to memory IDs?
Thanks.

Passing an object accross classes.

Hi all,
I'm trying to declare an object in one class and then pass that instance over to a second class, when I try to run my code I get "Debugger stopped on uncompileable source code" error!
I'm working with a series of JFrames, starting with a "welcome" screen and a "next" button:
    Order[] Order = new Order[99];
    int OrderNumber = 0;
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == btnNext){
            OrderNumber++;
            Order[OrderNumber] = new Order();
            Name Name = new Name(Order[OrderNumber]);
            Name.show();
            this.hide();
    }This sets up a new order and passes the object over to the next JFrame class.
The user enters some information into some text fields which is then stored in the object instance:
    Order Order;
    Customer[] Customer = new Customer[99];
    int CustomerNumber = 0;
    Name(Order Order) {
        SetupUI();
        this.Order = Order;
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == btnNext) {
            CustomerNumber++;
            Order.Customer[CustomerNumber] = new Customer();
            Order.Customer[CustomerNumber].SetName(txtName.toString());
            Order.Customer[CustomerNumber].SetTable(txtTable.toString());
            FirstCourseUI Menu = new FirstCourseUI(Order, Customer[CustomerNumber]);
            Menu.show();
            this.hide();
        }This seems to work fine, the object is passed over and I can commit the information to it. But this too uses the same method to send the objects over to the next JFrame, which should in turn begin adding some items for the customer:
    Order Order = new Order();
    Customer Customer = new Customer();
    FirstCourse FirstCourse = new FirstCourse();
    FirstCourseUI(Order Order, Customer Customer) {
        this.Order = Order;
        this.Customer = Customer;
        SetupUI();
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if(source == btnAdd) {
            String selectedItem = (String)lstMenu.getSelectedValue();
            Customer.AddItem(1, selectedItem);       // PROGRAM STOPS HERE
    }And this is where I run into problems, here is the AddItem method
    public void AddItem(int course, String item)
        int i = 0;
        switch(course)
            case 0:     // Drinks
                break;
            case 1:     // First Course
                while(FirstCourse[i] != null) {
                    i++;
                FirstCourse[i] = item;
                break;
            case 2:     // Second Course
                break;
            case 3:     // Third Course
                break;
            default:
                break;
        }As far as I can tell, this should work fine. I don't think the method itself is broken, the program just never gets to that point!
Any Ideas?
P.S. Sorry about the lack of comments in there, bad practice I know :\

Problem solved!
On the second JFrame where the user enters their name and table number, I was creating an object array of Customer - but my order class already has a Customer array! I was then passing over the wrong object array when the "Next" button was pressed.
    Order Order;
    int CustomerNumber = 0;
    Name(Order Order) {
        SetupUI();
        this.Order = Order;
    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == btnNext) {
            CustomerNumber++;
            Order.Customer[CustomerNumber] = new Customer();
            Order.Customer[CustomerNumber].SetName(txtName.toString());
            Order.Customer[CustomerNumber].SetTable(txtTable.toString());
            CoursesUI Menu = new CoursesUI(Order, Order.Customer[CustomerNumber]);
            Menu.show();
            this.hide();
    }It seems to be functioning correctly now :) Thanks for taking the time to look over it steve.

Trying to pass and object variable to a method

I have yet another question. I'm trying to display my output in succession using a next button. The button works and I get what I want using test results, however what I really want to do is pass it a variable instead of using a set number.
I want to be able to pass the object variables myProduct, myOfficeSupplies, and maxNumber to method actionPerformed so they can be in-turn passed to the displayResults method which is called in the actionPerformed method. Since there is no direct call to actionPerformed because it is called within one of the built in methods, I can't tell it to receive and pass those variables. Is there a way to do it without having to pass them through the built-in methods?

How to resolve a Lenovo PC that will not pass the Lenovo Splash screen with no access to Windows

Here is my problem and here is the solution!!!
My B540 Ideacentre would not pass the Lenovo splash screen. The only operational keys I had was F1 (BIOS) and F12 (BIOS options). F2 went to a light blue screen so no chance of even a one key recovery. Warrenty had expired four and a half months ago. I contacted Lenovo and after the guy told me to try F2 twice he said it was a HDD or other hardware failure and would cost around £200 maybe and also would take about two weeks.
AT THIS POINT YOU SHOULD NOT BE ANGRY FRUSTRATED OR PANIC. REMAIN CALM AND STOP AND THINK WHAT ACTUALLY WAS HAPPENING WHEN YOU LAST USED YOUR PC.
For me I remembered Windows had auto downloaded 8.1 and was asking me to install. Also my keyboard had lost shift W T Y keys. This told me that it was not a hardware issue but a software issue and perhaps from this update. My HDD was not clicking or beeping and this PC has a 2TB Seagate Barracuda which has a good reputation. Luckly for me I also have a Seagate external expansion 2TB and a 500MB expansion which was the HDD from my old HP Touchsmart which I converted into an external hard drive by buying a HDD enclosure with cooling fan and all leads from eBay for £25 and this is where the solution is.
If you can create an expansion drive so easily and access the HDD then why cant I do it with the HDD from my Ideacentre and of course you can. So first unplug your PC or laptop. Next remove the cover and unclip the HDD (which is easy with the B540. See user instructions). Next I removed my HP HDD from the enclosure and fitted my Ideacentre HDD in its place. Next you need a laptop or another PC. Switch it on and then connect your HDD to the laptop or PC via highspeed USB cable. My laptop is running Windows 7 Ultimate and of course has all the repair tools required. When the software has loaded you may get a box that will have two options. The first will ask you if you want to repair your files and the second to scan for bad sectors and to attempt repair recovery of sectors. Tick both boxes and click start. This is a long slow process but worth the wait. Nine hours later my HDD was ready. I connected my Seagate expansion to my laptop and moved all new files that I had not backed up. So at this point you should create a folder and move all your photos music videos documents etc to it. This can take upto three hours if you have never backed up before and are moving everything. Once completed I shut everything down and replaced the HDD into my Ideacentre. Make sure do not have any external devices connected such as expansions external drives headphones etc. Connect the power and switch on. The Ideacentre booted up and there was a pause at the splash screen then it went to a black screen and then by the miracle of logical thinking I was at my lock screen. I was never so glad to see the map of my home land "Ukraine". After jumping up and down with joy I then went in and all was as normal but to be sure I went into safemode and started a complete restore. This is the option where you completely format your HDD and restore as new. It takes a long time but it is the best option because you do not want this to happen again. When this has completed and you are in Windows do not wait a moment longer by playing with your photos or creating your desktop picture. Go to create a recovery drive (use a 32GB stick) and after that also make a copy to disc. Next go to command prompt (cmd) Admin and change a setting by typing bcdedit /set {default} bootmenupolicy legacy. This will now enable your F8 key to boot straight into safemode just incase you need to in the future. It will slow boot time a little but better to be able to get in to Windows than not at all for the sake of a few seconds.
Well I hope this helps someone out there and I know you may think its a lot to do but it is not. Ask a friend to borrow a laptop or PC and perhaps a HDD encloser. The rest is just time but when you see your lock screen you will not care trust me.
Cлава Україні!!! Героям слава!!!

Type diskutil to get a list of currently connected devices
Insert USB drive you want to use
Run diskutil again to see what your USB stick gets assigned eg - /dev/disk3
Run diskutil unmountDisk /dev/diskN (where N is the number assigned to your USB stick, in previous example it would be 3)
Run sudo dd if=/path/to/target.img of=/dev/diskN bs=1m (if you get an error, replace bs=1m with bs=1M
Run diskutil eject /dev/diskN and remove your USB stick
The USB stick will now be ready to use

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?

I am trying to set this map data using java code ,
     HashMap procADMap1 = new HashMap(5);
               PropertyTypeWS pType = new PropertyTypeWS();
               pType.setTypeIndex(2);
          AppdataDefImplWS appData1 = new AppdataDefImplWS();
          appData1.setName("Project");
          appData1.setType(pType);
          appData1.setMaxSize(400);
          appData1.setLOB(false);
     appData1.setDefaultValue("Project Default value");
          procADMap1.put(appData1.getName(), appData1);
          setVariableData("request","createNs","/createNs/namespaceData/appdataDef",procADMap1);
Then I am passing request object to the method which I want to invoke from bpel process.
I am able to deploy the application but when I do post message I am getting following exception,
NamespaceWithMap (createNamespace) (faulted)
[2004/09/09 18:35:54] "{http://schemas.oracle.com/bpel/extension}bindingFault" has been thrown. Less

Is there any other way to handle Map type in bpel process?
Thanks in advance,

Thanks for the quick reply.Actually the web service is already deployed on the server.What I want to do is use existing wsdl file of the deployed web service and invoke the method of the same using oracle PM.
If I remove element which uses apachesoap:Map type it just works fine also I am getting the complex object returned by the web service method.But when I try to set appDataDef which is of type apachesoap:Map(Axis conversion for java.util.Map and it uses namespace xmlns:apachesoap="http://xml.apache.org/xml-soap") I am getting the error.
Can you give me some direction to use this exising wsdl file to set map object or it is not possible.

Pass Value from one screen to another screen filter Parameter

Hi i am developing LightSwitch HTML client using VS 2013
need some ideas for,
I am having one browse screen for eg please refer the below,
BrowseEmployee
ID
Name
Age
1
Srikanth
25
2
Ashok
25
when i click on any row, it will lead to another screen (Not to the same entity View screen). In the another screen i am going to show with the lot of details,
ViewResourceAllocation
ID
Name
Role
Allocation
1
Srikanth
Developer
0.5
1
Srikanth
Architect
0.5
2
Ashok
Tester
0.6
2
Ashok
Manager
0.4
and in this screen i am pulling from SQL view entity, this will have ID field which is common to the previous screen (BrowseEmployee)
Now my question is,
1. If i click the ID 1 employee in the 1st screen here i need to show only the Employee ID 1 details alone.
2. Even i tried to pass the value as parameter to the filters in the second screen, nothing is working out.
so it will be convenient if i pass the value as filter parameter to the other screen.
Can anyone please tell me how to sort out this issue ?
thanks!

Hi Srikanth,
For this issue, you need pass parameter to another screen, this will help you,

How to Pass Java Objects between Web Dynpro and Java SAP iViews

Basically I have an SAP web dynpro iView that I do stuff with and I want to pass an object to another iView which is just a regular Java iView. From what I've read and tried, I can't just stick something in the session object and hope that the Java iView can pull it down the other end. I had a dream that it was possible (seriously).
Anyway, are there any possible solutions around? Please advice and share you throughts. I will try to dream about it again tonight and see if its really gonna work this time.
thanks for your help in advance

There is no easy way you can pass objects other than those supported by express such as String, map, list etc.
Though not advised, you can create a class with static variables to handle the storage of such java objects during transition between form and workflow. You will need to somehow identify the objects uniquely .

Passing CURR value to screen using PARAMETER ID's

Hi all,
I need to pass a value which is of type CURR to a screen field which is of type DEC using parameter id. As of release 6.10 only character-type field is expected to pass to screen fileds. I tried converting the CURR field to char type and pass the same to screen field,but didnt work as in the screen filed it expects some value with typr DEC.
Thanks in advance!

Hi Rob,
while debugging the code i can see the values of pid in SAP memory, but when i run the program to display those values on the screen field with type DEC,it kicks me out of the system.I commented that part of code and exceuted the program and then it went fine so i am for sure that it goes wrong at this part of the code.

Branching to DMS doc from SAP object trans screen(newly createdobject link)

Hi
I have created a new document type and been able to attach a new sap object to that DMS document and view it in the object link of that document in CV02n, Cv03N. My problem is how to display the document from sap object screen (vice versa is always possible)
For standard object already available such linking is provided by SAP
(like in mm03->Extras->Document data) but I have added a new SAP object say OIGV. How to browse to ducument data from o4v2, o4v3 transaction. Is there any generic strategy for enhancing each and every SAP object transaction screen to branch to its linked DMS document
With best of regards
Saurav Choudhury

Hi Sai,
regarding your description I would kindly ask you to go to transaction DC10 and mark a document type where the necessary object is linked under 'Define object links'. Choose the right object and display its details by double-click. Then you will see the field 'Create document' where you have to enter a value '1' (using transaction) or '2' (simple creation). Please enter a value and flag the 'Additional function' checkbox too.
Based on your description I'm sure that you are using the 'simple creation' mode for this kind of object type in the DMS customizing. Please note that for the simple creation of documents mandatory fields (if set in customizing) cannot be filled and this will lead to error messages.
Please note that the value "1" for the creation of documents is used to enable a user to simple attache a word file on object side without going to the transaction CV01n. Therefore the system behaviour is different then creating a document by CV01n and attaching a word file to it.
However, you can change the behaviour how the document is created from equipment master transaction if you change the customizing in transaction DC10 like this:
If you maintain the value "2" for creation of documents, the user is put to transaction CV01n for the creation of document info records. So maybe this would solve the issue.
Best regards,
Christoph

How can I pass an object to a function by value?

Hi
I have a function with an argument. this argument is an object. I don't want to alter this object. But java passes this object by reference and some fields in this object are altered after function return.
How can I pass this object by value and keep my original data unbroken?
thanks for any help

How can I pass this object by value and keep my original data unbroken?How you approach it is likely to depend on how much control you have over the code in question. If it's legacy code and has been badly designed, there's probably very little you can do to protect existing code short of a complete refactoring.
What you could do as an interim measure is:
1. Create an immutable wrapper to your existing mutable class.
2. Create new methods that replicate the existing ones, but take the immutable class instead.
3. Deprecate the old methods.
This won't break client code, but they will now get warnings when they compile and you can add documentation to point them to the new class/methods.
If you are in control of the code (especially if you're still in the design stages), you've got several options:
1. As Dr.Clap says, make your class immutable (probably best).
2. If this isn't possible, create mutable and immutable variants of your class. This is often best achieved by hanging them both from an interface.

Passing html object in a JSP to another JSP

Below, I have a jsp page I want to pass the object name "BP" and all its values to a jsp in another jsp page. I can't use the session object can I? The html the jsp creates is within a form.
I know the request.getParameter("BP") doesn't work because it must be a string.
out.println("<form name=myform action='RevUpdate.jsp' method=post>");
out.println("<PRE><Center><TABLE border = '5'>");
for (int i=0; i < vBP.size(); i++)
out.println("<TR><TD><font size='4'>" + ((Fetch_BP_RevLetter)vBP.elementAt(i)).getBP() + "</font></TD><TD><font size='4'><input type='text' size='3' maxlength='2' name='BP' value='" + ((Fetch_BP_RevLetter)vBP.elementAt(i)).getItemRev() + "'/></font></TD></TR>");

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
