Interactive problem in Web Dynpro for Java and Flex

Hi, all:
     Now I'm can use the FlashIsland to embed a flash developed by flex builder 3 in a Web Dynpro View, I have made the data transfer between Web Dynpro View and the flash, also have I got events of the flash in Web Dynpro View. But now the problem is that in the flex flash, how can I get the actions such as button action from the Web Dynpro View?
     Is there anybody that has the experience to deal with such a problem ? Can you give me some help ?
     Thank you all !

Hi
Are you sure it asked for JDK 1.9
Please let me know from where you downloaded JDK 1.9

How to develop Web Dynpro for Java and run it locally

I want to learn Web Dynpro for Java but still struggling with the running it locally in my PC. What software do I need to install in my own PC in order to do that? I have NWDS in place and I can write the code and compile it already. Thanks!

Hi Anthony,
You need to have SAP Web Application server (SAP WAS) to run all the webdynpro applications. WAS can be installed either on your local system or on a server which can act as a central server.
You can download WAS from SDN, which is a trial version. Check this link.
http://www.sdn.sap.com/irj/scn/nw-downloads
For checking the minimul system requirments for installing WAS please check the PAM (Product Availability Matrix).
I hope this solves you issue. Please revert back in case you need any further information on this.

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.

Angelo

Hardware requirement for Web Dynpro for JAVA

Hi Friends,
I am a starter in Web Dynpro for JAVA and about to develop web dynpro application in JAVA.Can anyone please guide me on the hardware requirement for this application of SAP?
Presently I have ECC 5.0 installed in 1 GB RAM using 160 GB harddisk.
Regards
Ashish.

Hi Ashish,
If you want to install NWDS only then as said 1g.b is sufficient.
But if it's Personal System then you have to install Portal also( WAS).
You will require minimum of 2g.b of RAM and 120g.b of hard disk.

Reg:Locking in Web Dynpro for JAVA.

Hi All,
When a user logged in the front end i am calling the lock function module(based on this locking mechanism is working) and when a user logged out i am calling the unlock function module(now the locked mechanism is getting unlocked).
now my problem is when a user closes the window abruptly without loging out,the unloeck mechanism should work at that particular instance.Please suggest me if this is possible or not in web dynpro for java.
Thanks,
Mahesh Nuli.

Hi,
I will give you two different solutions, use whatever you think fits best for you.
First One:
Whenever you call your "LOCK" function module, do not disconnect the ModelInstance. Create a Locking method in Java which returns a "com.sap.tc.webdynpro.modelimpl.dynamicrfc.DynamicRFCModelClassExecutable" instance. It should look like this:
InputClass inputInstance..
node.bind(inputInstance);
inputInstance.execute();
if fails, return null;
otherwise, return your inputInstance;
Keep this inputInstance into some Context Attribute. Whenever you wanna "Unlock", you can disconnect this input from the backend system.
InputClass inputInstance = wdContext.getInputInstance();
inputInstance.modelInstance().disconnectIfAlive();
This will work for all the cases you are currently having problem. However, this solution holds one connection.
Second One:
Assuming your transaction runs in one View, you can set this View lifecyle to "when_visible" - Doing that, whenever you navigate "away" from this View the method wdDoExit of that ViewController will be executed.
In this appoach, you dont need to store any "InputClass" - You can perform your Lock and disconnect from the backend. In your wdDoExit method you can code a "Disconnect If Connected" method.
Use whatever fits best.

Daniel

Design header in Web Dynpro for java

Dear experts
I used PageHeader UI Element for design header in web dynpro for java. How to insert a image and set padding logo in page header?
Ex : Create a SAP header includes the content as SAP logo, application title, functions, user name, logout button.
Thanks.

Hi,
I couldn't understand your requirement for keeping an image in page header but i suggest you not to do so, because it is not a good practice and creates a performance issue. Page header UI element is not much customizable for same purpose and should not contain interactive UI elements according to [UI Element Guide|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b06c8c9a-19a4-2b10-d985-9ae7a4383478]. You can also refer to the same document for the usage of the Page header and other UI Elements its a very useful and nice article.

Creating a purchase order in web dynpro for java.........

hello all,
i am new to web dynpro for java.i have already done an application
"Creating a Web Dynpro Application Accessing ABAP Functions" this application
have good document on sdn.
this application is working fine .
Now i got an requiremnt for creating a purchase order in web dynpro for java.
in normal report when i call the bapi the parameter are the header, headerx,item, itemx is an internal table.
CALL FUNCTION 'BAPI_PO_CREATE1'
EXPORTING
    POHEADER                     = HEADER
    POHEADERX                    = HEADERX
POADDRVENDOR                 =
TESTRUN                      =
IMPORTING
EXPPURCHASEORDER             =
EXPHEADER                    =
EXPPOEXPIMPHEADER            =

i just want to know how can i fill these internal table in web dynpro
for java to create an application accessing "Bapi_po_create" .
Thanks

Hi Gopal,
I'm not sure what is your issue, it seems you're not really understanding how the Model structure works in WDP.
I'll assume few things here, like you know how to Import the Model into the WDP, and you know a little bit about what Java Classes will represent this Model in the Project.
Try these steps:
1. Import your Model into the Project;
2. Open your Component Modeler, create a Data Link between your Model / Component (Or Custom Controller, as you prefer)
- You can also use the "Apply Template -> Service Controler"
3. Map the Input of your Model as the Main Node, check the Input Tables (you prob. will have two, POITEM = ITEM - POITEMX = ITEMX)
4. Also, check the Return box, since this is BAPI return (You can use to display Backend messages)
Now you have the Model mapped into your Controller, you need to develop the Java function to execute it.
1. Create a new Input class, like
BAPI_PO_CREATE1_Input purchaseOrderCreateInput = new BAPI_PO_CREATE1_Input();
2. Bind your Input Node, in the Controller, with your Input Class;
wdContext.nodeBAPI_PO_CREATE1().bind(purchaseOrderCreateInput);
3. Set any Import parameters you need:
purchaseOrderCreateInput.setEXPPURCHASEORDER(XXXX);
4. To Add references to the Table, you will perform something like:
First, you need to know what "Structure" you need to add (POItem Structure) - You have a Java class that represents that Structure..
POITEM_Element poItemElement = new POITEM_Element();
poItemElement.setPROPERTY();   /// Set your Properties
purchaseOrderCreateInput.getPOITEM().add(poItemElement);
5. Execute your Input,
purchaseOrderCreateInput .execute();
Hope it helps,
Regards,
Daniel

Creating Sales Order using Web Dynpro for java

Hi SDN,
I am new to Web Dynpro for java. I have developed an application for creating a sales order using adaptive RFC Model using BAPI. It's working fine when i create a single order. I wanna create SO with more than one line item. I have used the Table UI Element to do so. But i could not able to enter the 2nd item details. Please suggest me how to pass more than one line item from the Table UI element.
Thanks in advance.
Regards,
Basha

Hi Basha,
Do you need to display the header items and detailed items?
If the BAPI Contains Output values in R/3 side.
I mean to say if BAPI contains 4 line items.u can get thru wdjava the followinf way.
1. Create webdynpro application.
2.Import the model.
3.Create Customcontroller and model binding .
4. Write the execute method in controller.
BAPI b = new BAPI();
WdContext.node<BAPI>.bind(b);
give inputs for BAPI
b.setname(" ");
b.setno("");
wdContext.currentBAPI().modelObejet().execute();
wdContext.node<output>.invalidate(); in try catch
5. create view or when u give the dynpro application its
in the add custom to view and drag BAPI custom to view .
6.Crete UI for ur table thru insertTemplate table directly mapp the output values.
7. deploy and run
U can get the out line items .
Or any thing else post ur requirement.
Thanks

In Web DYnpro for java there is any Configuration controller?

Hi,
Experts,
I am having a confusion that is there any "Configuration Controller" present in Web dynpro for java.Where as i know that it is present in Web dynpro for abap could u please pass some idea on it.And how can identify the type of component in metadata files.
Thanks in advance,
Shabeer Ahmed.

Hi,
you have Configuration Controller that we can call it as CC in Webdynpro application which developed using FPM that is Floor Plan Manager, which is used as part of developing the ESS and MSS business package.
The configuration Component is used to difine all the View Navigations and Road Map steps and define prespectives, and Vac's, Events for navigation from one view to another view.
go through this link u came to know abt FPM

Catching errors in Web Dynpro for Java when thrown from RFC Raise Exception

Hello Developers,
I'm looking for information that explains how a Web Dynpro for Java application responds and processes errors that are thrown from a Raise Exception event within an RFC.
The Exceptions do not appear to be part of the Model and I can't identify how they get processed.
When rfc HRXSS_CAT_WD_RECORD raises exception PERNR_NOT_LOCKED this exception is passed back to the calling webdynpro CAT DC that displays the exception on the web page along with the log.
I would like to display a friendlier message and without the log. Any information on how to customize the handling of this error would be greatly appreciated.
Thank you,
Terry

Why Web services are used to send data not HTTP in Web dynpro for Java?

Is Web Dynpro for Java supports Web service , RFC as communication to other systems why http cannot be used in Wweb dynpro for java.........
Thanks and Regards,
CSP

Hi Pradeep,
Yes, Web Dynpro java supports web service, you can expose your web service as RFC Model to
communicate with others system. As per as HTTP is concern we don't have any
supportive method in web Dynpro. Insted of HTTP we use context in web dynpro to communicate.
