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

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.
regards,
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.

the UI technology "web dynpro for java", i will to create UI elements dynamically.How can i control this
dynamical UI elements to keep layout ?

Hi,
yes you can do that....
for exaple if you observe SDN...
you can imagine like....
A big Transparent Container(TC)....
Inside that number of other TCs(depending upon the question nd its replies...)....
In side each TC, again around 9 UIElements....
one for menioning what is the question/reply?
other for your description of question/reply...
other for your name,
displaing your fourm point... etc...
So it will be
for(loop till your (Question+No of replies))
Create Transparent Container....
Add Childs to the Container...
Decide your layout....
In case if you want to know how to create UIElements dynamically....

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

Best practice for Web Dynpro for Java to connect to SAP HR

What is best way to connect Web Dynpro for Java application deployed in SAP portal to connect to SAP HR ?
Is it good practice to connect to underlying SAP database ( eg oracle) directly to get the data or is there a better way ?
This below article describes to connect to external DB, however Is there any other way for SAP HR ?
http://wiki.sdn.sap.com/wiki/display/WDJava/WebDynproApplciationwithDatabaseMS+Access

Hi,
There are 2 supported ways :
First is to use JCO connections to call abap RFC enabled function modules. (BAPIs for example)
Second is to call SOAP web services (HR enterprise services for example)
You should never access directly database tables...

Olivier

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

External jars in Web Dynpro for Java CE 7.1.1

Hi there,
Can you give me some guidance for including external jars in Web Dynpro for Java (CE 7.1.1)?
I vainly tried for some hours now to get my external jars running in the new version of web dynpro (part fo Composition Environment 7.1.1).
The routines described in some other threads didn't help me. For example, in CE 7.1.1 there's no DC Metadata that would allow me to add an external library.
FYI, in the error message during build it simply says the package is not found.
My error is javac ERROR: D:\test.jdi\LocalDevelopment\DCs\demo.sap.com\retail\_comp\src\packages\com\sap\demo\retail\javafiles\DomParser.java:12: package com.sap.semprom.retail.sc does not exist
javac ERROR: import com.sap.semprom.retail.sc.BoundEvent;
Thx in advance!

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
