Hi Friends,

Hi
If you want to try out using ADOBE Flash Islands with WDJ, you would need to download SAP CE 7.1 EhP1 trial version, if not done so already.
The following link may help you in building the WDJ component with Flash Islands..
The specified item was not found.
If you donot want to develop the Flex project you can download the .swf file provided by the SAP mentors:

Adobe Interactive forms & WebDynpro for java problem with IE7 and IE8

I have Interactive form ui-element in WebDynpro for java (ver. 7 SP 10) application. It works fine with IE6, but in IE7 (or IE8) it doesn't show that ui-element at all. We have tried to change IE7 security & advanced settings, but we have not made any progress. We have also tried to install/uninstall different Adobe reader versions etc.

I know a little more about the problem now. After viewing the XML source I change the property of the inputfield.
It was like this:
<field name="verdipers_felt" y="130.7001mm" x="180.1801mm" w="101.6004mm" h="44.4501mm" locale="no_NO" access="ReadOnly">
but i changed the access to be nonInteractive
<field name="verdipers_felt" y="130.7001mm" x="180.1801mm" w="101.6004mm" h="44.4501mm" locale="no_NO" access="nonInteractive">
now view2 shows the linebreak as in view1... Buut! when im going back to view1 from view2, the linebreaks gets converted into spaces
thats pretty wierd, aint it?

Hi,
Iterate through the result set object
populate the context node
Ex:Replace the context nodeName with that of yours.
ResultSet resultSet = stmt.getResultSet();
 //Iterate through the resultset
 while(resultSet.next())
 //Create element of the context node
 IWDNodeElement nodeElement = wdContext.nodeOrders().createElement();
 //assign value from the database to the context attribute
 //Replace attributeName with your attribute name
 //Replace value with resultSet.getShort("<ColumnName>")
 nodeElement.setAttributeValue(attributeName, value);
 //Add the element to your node
 wdContext.nodeOrders().addElement(nodeElement);

Hi Suresh,
You can have the MDM JAVA API javadocs from the link
http://help.sap.com/javadocs/MDM/SP06P2/index.html
There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
Right click on project-> properties->Java Build Path - > Add external JARs
At run time you can add them the reference in
Right click on project-> properties->web dynpro references->library reference.

The project was not built since its classpath is incomplete. Cannot find the class

Create a ViewSet with properties column 1, rows 3.
1. In the tool selection list, select Embed View.
2. In the layout area of the Navigation Modeler, click on the cell of the view set in which the view is to be embedded.
3.In the wizard, choose Embed New View and, in the next window, enter a name for the view.
4.Use the package that you entered for the component definition or select another package by choosing Browse.
5.Choose Finish.
Create 3 views with names search screen,results screen and detail screen.
Use plugs to navigate.
II. Display one view at a time:
Create a main View. Insert ViewContainerUIElement
Open Navigation Modeler.
1. In the layout area of the Navigation Modeler, click on the cell of the ViewContainerUIElement.
2.In the wizard, choose Embed New View and, in the next window, enter a name for the view.
3.Use the package that you entered for the component definition or select another package by choosing Browse.
4.Choose Finish.

How can I read cookies in WebDynPro for Java

Hi,
in WebDynPro for Java I found a possibility to to get a "request-object" like the standard "HttpServletRequest-object"
IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
IWDRequest request = protocolAdapter.getRequestObject();
debugEnabled = (request.getParameter("Debug") != null);
With this request-object I can read request-prameters but I couldn't find a possibility to get cookies from the request.
There is no method like the "getCookies().method" in the HTTPServletRequest-Interface:-((
Has anybody an idea, how I can read cookies in WebDynPro for Java ?
Regards
Steffen

Hi,
This is the latest update I could look for regarding cookies and webdynpro.
Panic - WebContextAdapter is depracted - no more cookies now?

Problems between Xcelsius and WebDynpro for Java

How should I do to show Xcelsius in WebDynpro for Java?
How should I transport data between Xcelsius and WebDynpro?
How should I control WebDynpro with Xcelsius?For example,firing plugs in Xcelsius like in WebDynpro to change one view to another.
How should I do to execute a Java method in Xcelsius?For example,scheduling a job on clicking a button in Xcelsius.
Besides these,I also want to know the same problems between other BOE contents and WebDynpro for Java.
Regards,
Abe

Hi Pradeep:
Well that purely depends on the business application (project) your client is proposing. Following are very few factors which will drive for creating web-based applications:
VC: it's a UI modeling tool (non-programming) for creating rapid creation of web-based applications.
WD: its a powered by Java and ABAP with which you can create robust business applications.
If your client is very choosy about rapid application development, reporting, rich user interface, to reduce TCO then VC is the choice. Or if the project contains typical integration with SAP and non-SAP systems, complex business logic development, integration with WCM systems...etc then WDJ is the option.
If youve some sort of custom development with facilitating the Development Infrastructure (NWDI) then WDJ is the only option I could say.
We hope with NW CE 7.1.1(referred by Priyanka Singh) tighter integration between these TWO tools may over come the ambiguity of using them.
Tnx,
MS

How to learn webdynpro for java/ABAP

hI Experts,
i am new to webdynpro technology.
and i am having the knowlgedge on Portal contenet development&administration,and having the strong knowledge on Visual composer7.0,7.1 and also trined in ABAP(currently i am not useing it).
now i wants to learn webdynpro for java/abap.

what are the minimun skills i need to be a good webdynpro developer for java/ABAP. ?
is it requires straong java knowledge since i am not familiar with that too much ?
please give your valuable inputs
Thanks&Regards,
Govindu

SAP uses Webdynpro to build portal content, which later will be configuted as an Iview in the enterprise portal. Webdynpro comes with Java and ABAP flavors. Both have in general the same functionality,the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
If you are good in ABAP go with ABAP Webdynpro, if you are good in JAVA, go with JAVA Webdynpro. But you will get good opportunities in JAVA Webdynpro compare to ABAP Webdynpro.
Thanks,
Chenna.

Retrieve already deployed webdynpro for java source code from portal server

HI ,
We have webdynpro for java apllication already deployed on the J2EE server. We found the ear file related to this application. But I am not able to make any changes to the ear file in NWDS as it cannot be directly imported into NWDS. We do not have NWDI for software logistics and the resource who built the WDJ application has left the company. Is there any way that I can retrieve the complete source code of the application from the portal. I need to make some changes to Webdynpro component and its view. I have worked with basis team to retrieve the ear file from portal server. But I could not make any progress just with the ear file. Thank you for your help in advance
Regards,
KMM.

You are probably breaking some license agreement by de-compiling the content of the 'war' files. Why not ask the people who provided the 'war' file if you could have the source and build system.

Hi, Michael,
First and formost, Welcome to the amazing world of WD Java. Since you have some experience with C#, coding will not be a mammoth task for you. As per, basic concepts of WD Java are concerned, you can refer the following Link:[Concepts Of WD Java|http://help.sap.com/erp2005_ehp_04/helpdata/DE/14/c897427f18d06ae10000000a155106/frameset.htm]
To try your hands on WD Java, there are few sample applications that you can refer:
