Web Dynpro with Bapis using Miniwas 6.20 or Sneak Preview 6.40 ABAP

Does anyone know if I can I use a web Dynpro that uses BAPIs to connect to a Miniwas 6.20 like a Backend system?
I have the SLD configuration OK, I was able to create the Jco connection, but when I test the Metadata application with this Technical System (Miniwas 6.20) at the Content Administrator I get an error message: "Group PUBLIC not found" (I also tried with SPACE, like a Logon Group). I have the corresponding settings in the service file on Windows folder (sapmsBSP 3600) and the others settings too.
I think the problem is to try to define Logon Groups at this kind of R/3 system (Miniwas 6.20) ... It's possible to use Logon Group with Miniwas?
I want to know if somebody had tried to do this practice (Web Dynpro using BAPIS)against to Miniwas System.
Please I would like to get a yes or no answer
Janett

Hi,
You have to configure the PUBLIC logon group in SMLG transaction.
Once configured the SLD and JCO-Destinations in the WebDynpro Content Administrator, we had the same problem with METADATA_DIRECTORY JCO-Connection. When we tested it, we got an error related with the PUBLIC LOGON GROUP. This JCO destination is a metadata directory connection and use the SAP message server to connect to the PUBLIC logon group.
You can create the PUBLIC logon group easly with SMLG, but it is necesary to add a "Logon Favorite Storage" in "SMLG Transaction - Display control/status Area" called PUBLIC too.
More information at:
http://help.sap.com/saphelp_nw04/helpdata/en/28/1c623c44696069e10000000a11405a/content.htm
After that, all JCO connections and the webdybpro application should run fine.

SAP Web Dynpro With Java

Hi Guys
A situation at work has forced me to learn web dynpro with java. I already have some experience with the ABAP web dynpro . Now the question is how much "java" do i need to learn to learn sap WebDynpro based on java. Should I first try and get a fair 'hands on' on core java and then shoot for web dynpro or should I take the other approach, that is just learn as much java as is required for web dynpro . Any suggestions?
thanks
sameer

Hi Sameer,
I believe you need not thoroughly know Core Java to begin for Web Dynpro Java but yes, you should have a fair idea about object, class and exceptions that i believe you would already have after working in ABAP. The UI elements can be just inserted into the component by drag and drop and codes correspondly would be auto generated. Only for customization of some functionalities, you will have to write code in Java using APIs.
Just go through the following tutorials recommended by SAP to start over Web Dynpro Java on NWDS.

Java Web dynpro with ABAP Clients?

Morning,
We have a situation where we would like to use a Java Web dynpro with multiple ABAP backend data sources. This is for autorization as well as data. We are not using Enterprise Portal.
We've created a pair of system Jcos and mapped them to the Web dynpro via the URL. This works and the correct data from the correct Client is retrieved depending on which pair of Jcos we define in the URL.
The problem we are having is that we are only able to logon using the ABAP Client defined in the ume....master.client parameter.
Is there a way to achieve this (again without EP) either in the system configuration or programatically in the web dynpro?

Hello,
Thanks for the updates. Actually my query is we have a SCM 5.0 system which has a java stack in it. But now we are going to upgrade it to SCM 7.0. - Is SCM 7.0 has a java stack ?
If it doesn't have , can we upgrade SCM 5.0 to SCM 7.0 without Java Stack ? Is it posssible to upgrade without Java Stack or not ?
Is it possible that we can convert Java Stuff into ABAP web dyn pro ? If yes , how shall we can achieve it ? If not, how shall we proceed in an alternate way ?
Thanks for your help in advance.

Problem Web Dynpro Java applications using JasperReports

Hello all,
We have followed the footsteps of these blogs but we can not make it work.
Part I --> Part-I: Print Web Dynpro Java applications using JasperReports
Part II --> Part-II: Print Web Dynpro Java applications using JasperReports
Part III --> Part-III: Print Web Dynpro Java applications using JasperReports
Details system: 7.02 SP3
We believe that the problem is in the library, because it finds them.
1) We created project as a DC external library with *.jars
2) Public part DC external library.
3) Add public part of DC Library into new project DC WebDynpro Java.
4) Development Component -> Build is OK
5) Development Component -> Deploy is OK
6) Test app ERROR.
When we run the application shows the error:
The initial exception that caused the request to fail, was:

Hello John,
Thanks for the link. We have performed the steps in this blog:
1) Create DC Project "External Library" with name js/jars:
- Add *.jars in folder Libraries.[Screenshot Libraries|http://img846.imageshack.us/img846/8395/jsjars.jpg]
- Add archives (*.jar) to public part with name ExternalLib. Which option to choose?
a- Provides an API for developing/compiling other DCs (Option chosen)
b- Can be packaged into other build results (eg SDAs)
- Development Component -> Build
Step 1 is OK.
2) Create "J2EE Server Component / Library" DC with name js/lib:
- Add Used DC -> public part project ExternalLibrary -> "ExternalLib"
- Specify both build time and run-time dependency here and strong.
- Generated SDA file in <var>gen/default/deploy</var> How do we check that it contains <var>js.jar</var>?
- folder gen/default/plublic/defLib/lib/java then you meet *.jars files again. is OK.
- Development Component -> Deploy.
- Go to Visual Administrator. We found the library js/lib, but has no associated *. jar. It is the problem.[Screenshot Visual Administrator|http://img542.imageshack.us/img542/5537/visualadminlib.jpg]
3) Create "WebDynpro" DC with name pdf_jasper
- Add used DC (defLib) to WebDynpro DC with option "Build time".
- WebDynpro References -> Library references --> add <var>jslib
- Deploy
- Run error: java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

Integrate Web Dynpro with Flash Viewer for JasperReports

Hello,
I am trying to integrate the Flash Viewer with Web Dynpro in order to render the jasper reports generated in my web dynpro component. I am using a Flash Island within the view which has the SWF file bound to it.
I need to pass the URL of the XML report to an attribute called FlashVars of the embed tag, where the flashviewer SWF file is embedded.
What I have done so far is: created a property named "FlashVars" for the flash island, and then pass the file location of the generated report to it. However I am not getting the report rendered in the Flash Viewer.
Best Regards,
Baez

How to use JCo Provider Service w/Sneak Preview and Test Drive

I have both SAP Web AS Sneak Preview (6.40) and MiniWas 6.20 Test Drive installed on a single system. I have implemented a Java server program which can be RFC called from an ABAP program using JCO.
The only disadvantage to this process is that I must manually run the server program each time I bring up the J2EE system.
I would like to set things up so that when I start the WebAS 6.40 J2EE system, the server function can be automatically registered (if I'm using the correct terminology - not at all sure about that...). It looks to me that I should be able to use JCo Provider Service to do what I want to do, but I don't know how to do any of the session bean creation and I esp. can't seem to find out how to run the J2EE Visual Administrator, which the documentation I've found leads me to believe needs to be used.
Is there a tutorial, or example, that will lead me through this entire process? I have the ABAP calling program working OK, and I have the Java JCo server program working ok - I just want to create something in Java that will operate like a good old C Language function installed as an RFM.
Can anyone help? Is it possible?

Stefan:
Well, I guess I'm stuck at the first step.
As I understand it, I have to use the Visual Administrtor to register the Web AS 6.40 Sneak Preview system as an RFC destination. When I bring up the Visual Administrator, it has essentially two tabs showing: Dispatcher and Server. It's inviting me to define a connection and Login. So, Q1: Is it inviting me to login to the J2EE or the Web AS? Either way, I am never able to login - I get this error:
com.sap.engine.services.security.exceptions.BaseLoginException: Cannot create new RemoteLoginContext
I used all of the NetWeaver sneak preview defaults when installing, and I recorded these:
Type               Account
OS User            Compaq-laptop/J2EAdm
OS User            Compaq-laptop/SAPServiceJ2E
DB User            SAPJ2EDB
J2EE Engine User   Administrator
J2EE Engine User   Guest
Q2: Is it possible to do what I'm trying to do with the Sneak Preview system?
Or am I trying to connect and logon to the Web AS 6.20 Test Drive (I don't think so...)? I used the defaults when installing the Test Drive, and have these users:
BCUSER
DDIC
Is it one of these I should be logging onto?
Also, Visual Administrator wants a port specified on the J2EE Engine connection paramters - what port should I be specifiying?
Can you get me past this dilemma, Stefan? Thanks...

How to use a CAS in web dynpro with NWDS 7.0

Hi, all.
I implemented a cas project (some entity services and application services). Now I want to use it in a web dynpro project.
I know how to do that with NWDS 7.1, but it seems something differernt with NWDS 7.0.
Can anyone give me a hand? Thanks.

hi
CAF Core project comes with a sub-project WebDynpro.
You can implement business logic using CAF Core Service ,integrate it in WebDynpro UI.
1)Select your CAF project root , right click on it and select u201CCreate Web Dynpro Modelu201D from the context menu.
2) Switch to the Web Dynpro Perspective
3)You can find the CAF Core services have been generated and are available to the WebDynpro component.
you can find caf services under modelclasses of webdypro project .
4)Then you proceed with creating component etc..

Download Excel file through Web dynpro with no windows open?

Can we have a web dynpro application that just returns an Excel file in the response with no open windows? Similar to a java servlet that is used to download a Excel file?
This basically means that I cannot use wdComponentAPI.getWindowManager().createNonModalExternalWindow()
Java Servlet Code
HttpSession session = request.getSession();      // get a handle on the session id
response.setContentType("application/download");
response.setHeader("Content-Disposition", "filename=RTIS_Report.xls");
PrintWriter out = null;
out = response.getWriter();
String report = request.getParameter("REPORT");
JCO.Table lines = download(request, session, report);
for (int i = 0; i < lines.getNumRows(); i++) {
     lines.setRow(i);
     String content = lines.getString("LINES") + "\n";
     out.write(content);
     out.flush();
out.flush();
out.close();

Hi,
I think you can use IWD Cached Web Resource to achieve this..
See the below code FYI..
public void downloadToExcel( )
    String fileName = "Customer" + ".xls";
     IWDCachedWebResource cachedExcelResource = null;
     try
          File f = new File("Customer.xls");
          WritableWorkbook workbook =   Workbook.createWorkbook(f);
          WritableFont black = new WritableFont(WritableFont.createFont("Trebuchet MS"),WritableFont.DEFAULT_POINT_SIZE,WritableFont.BOLD,false,UnderlineStyle.SINGLE,Colour.BLACK);
          WritableCellFormat blackFormat = new WritableCellFormat(black);
          WritableFont blue = new WritableFont(WritableFont.createFont("Trebuchet MS"),WritableFont.DEFAULT_POINT_SIZE,WritableFont.NO_BOLD,false,UnderlineStyle.NO_UNDERLINE,Colour.BLUE);
          WritableCellFormat blueFormat = new WritableCellFormat(blue);
          WritableSheet sheet = workbook.createSheet("Customer", 0);
               Label label;
               String[] header={"Corporate Code","Batch ID"};
               for (int i=0;i<2;i++)
                    label = new Label(i,0,header<i>.toString(),blackFormat);
                    sheet.addCell(label);
               WritableCellFormat integerFormat = new WritableCellFormat(NumberFormats.INTEGER);
               jxl.write.Number number;
               // Reading the contents
               for(int i=0;i<wdContext.nodeVn_DownloadToExcel().size();i++)
                    String strCorpName = wdContext.currentContextElement().getVa_CorpCode();
                    String strBatchID =     wdContext.nodeVn_DownloadToExcel().getVn_DownloadToExcelElementAt(i).getVa_BatchID();
                    label = new Label(0,i+1,strCorpName,blueFormat);
                    sheet.addCell(label);
                    label = new Label(1,i+1,strBatchID,blueFormat);
                    sheet.addCell(label);
               workbook.setColourRGB(Colour.LIME, 0xff, 0, 0);
               workbook.write();
               FileInputStream excelCSVFile = new FileInputStream(f);
               IWDCachedWebResource cachedWebResource = null;
               if (excelCSVFile!= null)
                    cachedWebResource = WDWebResource.getWebResource(excelCSVFile, WDWebResourceType.getWebResourceType("xls","application/ms-excel"));
               cachedWebResource.setResourceName(fileName);
          cachedExcelResource = cachedWebResource;

Security Provider for a web dynpro with tool Visual Administrator

Hello all,
after deploying successfully my web dynpro on the J2EE 7.0 WAS, I'm trying to set up authentication to it but I cannot find my applicaiton in the list of policy configurations of the Security Provider entry. When I try to add the path to my local web dynpro, the engine doesn't find it.
I have noticed that all other policy configurations reference a servlet_jsp application. Should I transform my web dynpro into a servlet_jsp? How do I do that?
Thanks for your input,
Tanguy Mezzano

Hello Marcel,
in fact, I don't succeed to redeploy with another provider name... I have undeployed my webdynpro with SDM on the Java stack, but from NWDS, when I change the application-j2ee-engine.xml and application.xml files, and that I rebuild the webdynpro, when I run and deploy, it always redeploys under the former provider: local.
When I create the application, I tell to use the existing component, should I select create a new one, but that means that I have to rebuild the whole application.
Will then the webdynpro be in the Security Provider list, so that I can configure it with http header?
Thx for your help,
Tanguy

Web Dynpro Callable Object : use of RFCs

Hi All,
I've to create a callable object using Web dynpro.
In this web dynpro to display a table data populated by calling RFC and we need to select one row of the table and sent it as output parameter.
My question is how we gonna set the getDescription Method in this case for creating the Callable Object?
How we define the execute Method in the Interface Controller.
Where I should bind the Model to Controller (Component Controller / Interface Controller)
Can someone explain how we gonna use RFC in Web dynpro while calling it as Callable Object.
Thanks
Srikant

Hi,
You need to have the SCs for local development of Web Dynpro callable object.
Refer the following documents for more details:

Web dynpro with adobe interactive forms and button submit

Hi,
I'am new with webdynpro and adobe interactive forms so i just trying some example with an adobe interactive form with a submit button event handler inside the webdynpro. But i can't catch the event handler submit that i creaate on onSubmit property of the interactive form.
Can anyone help please.
Thank you very much.

I think I understand but just to make it clear. I use texts created using function module "SAVE_TEXT". In my Web Dynpro I select one or more of them and use the button "insert text" (with appropriate functionality behind it) to insert them to specified location in my PDF form opened in this Web Dynpro. Considering what you said it is not possible to replace this "insert text" button by drag and drop functionality. Am I correct?
Btw great job with the book "Next Generation ABAP Development" Thomas!

Hi Experts,
We have developed a web dynpro component with adobe flex integration. In development system everything is ok. Now the object moved to quality. In quality we are not getting the landing page. I checked in debug mode that the control come into SAP and code got executed. Finally the message which is issued from SAP is displaying in the page but the remaining page is blank. What reason might cause for this defect. If any one faced same kind of issue earlier. Respond to my request if you know the answer.

Hi Romero,
Ur guess is correct, i have investiagte in the system, the variants saved a $tmp, thats why it is not migrated.Later i migrated the variants. Now it is perfectly working. Thanks for the inputs.. Sorry for the delay response.
