How to access(connect) BI Data in webdynpro for java applications

Hi ,
is there any way to access and display the BI data in portal using webdynpro for java applications like we did in Visual composer.
if not how to integrate the BI data in webdynpro applications ?
Regards,
Govindu

Hi,
Yes there are ways to do it. But may your scenario and the scenario for which I have done may differ.
You can use openhub to get the data in a flat file and then read it into weddynpro through a java service OR
You can use DBlink(which i have done).
Please refer the link below:
[Link|Data from BW to Oracle.;
This I have done in NW04s. Not sure whether a better solution is available in the newer release.
Hope it helps.

PDF generation from Webdynpro for java application

Hi all,
I have a scenario in which a PDF has to be generated from the datils present in a table in the same view, on click of a button. I have found many solutions for generating interactive forms but I need to generate it from the code directly. I have also found an application for generating an excel sheet from the table data but it is not working with PDF.
So anybody suggest me how to do it or please refer any applications that have been done.
Thanks in advance.

Hi marco,
Sorry for the late reply.
I have got an application to generate an excel file and i will paste that code here for your reference.
    byte[] excelXMLFile;
    IWDCachedWebResource cachedExcelResource = null;
    String fileName = dataNode.getNodeInfo().getName() + ".xls";
    try {
      // create Excel 2003 XML data as a byte array for the given context node, attributes and headers
      excelXMLFile = this.toExcel(dataNode, columnInfos).getBytes("UTF-8");
      // create a cached Web Dynpro XLS Resource for the given byte array and filename
      cachedExcelResource = this.getCachedWebResource(excelXMLFile, fileName, WDWebResourceType.XLS);
      // Store URL and filename of cached excel resource in context.
      if (cachedExcelResource != null) {
        wdContext.currentContextElement().setExcelFileURL(cachedExcelResource.getURL());
        wdContext.currentContextElement().setExcelFileName(cachedExcelResource.getResourceName());
        // Open popup window with a link to the cached excel file web resource.
        this.openExcelLinkPopup();
      } else {
        wdComponentAPI.getMessageManager().reportException("Failed to create Excel file from table!", true);
    } catch (UnsupportedEncodingException e) {
      wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
    } catch (WDURLException e) {
      wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
In the above code "excelXMLFile" is a byte array in which the data that has to be appended to the pdf (in xml format) is present.
the toExcel method is used to convert the data in the table(i.e., the data that gets populated in the nodes of the view) in to XML format.
My Problem is when i change the filename to .pdf extension and the WDWebResourceType.XLS to WDWebResourceType.PDF and execute the application the Acrobat reader is getting opened but it says
"unsupported file type or the file has been damaged" .
I mean i am unable to put data into the file.
So, please help me in this regard.

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.

Webdynpro for Java Edit and Save.

Dear all,
ter cal
iam working on webdynpro for java i want simple code for EDIT and SAVE after calling a rfc in for using NWDS webdynpro for java.
1)HOW TO SAVE AND EDIT THE FRONT WEBDYNPRO FOR JAVA APPLICATION
2)AFTER SAVING AND THE DATA THAT SHOULD BE SAVED IN PA30 ARE PA20 AND IN PARTICULAR TABLE ALSO.
PLEASE GIVE ME GOOD TIPS.

Hi Kishore,
Creating/Updating entries in tables through Bapis (RFC calls) work in the same way as it is done for other Bapis like those for returning values or even structures. All you have to do is
1. Import the model, create a model node in your context and bind it to the Input structure of the model under used models.
2.Create an istance of the Model input structure, like
 Z_Test1_Input input = new Z_Test1_Input();
3. Set attibutes directly under the input structure
 input.setAttr1("XYZ");
4. Set attributes under any other structure under Input Structure by first creating the instance of the sub-structure
 Z_SubStruct1 subStrc1 = new Z_SubStruct1();
 subStrc1.setSubAttr1("ABC");
5. Add all available instances of sub-structures to the instance of input structure
 input.set<SubStruct1>(suStrc1);
6. Add all available instances of tables under Input Structure after setting attributes within using
for (int iCount = 0; iCount < wdContext.nodeVn_ContactInfo().size(); iCount++) {
 Z_Table1 zTable1 = new Z_Table1();
 IPublic<YourComponent>.IVn_Table1Element tab1Ele = wdContext.nodeVn_Table1().getVn_Table1ElementAt(iCount);
 zTable1.set<TableAttr>(tab1Ele .getVa_Attr1());
 input.add<Table1>(zTable1);
7. Bind the instance of input structure to the model node.
 wdContext.nodeMn_TestModel().bind(input);
8. Execute the model object and then invalidate the output structure under model node (Put this code in try catch block)
 wdContext.currentMn_TestModelElement().modelObject().execute();
 wdContext.nodeMn_TestModel().nodeOutput().invalidate();
9. Retrieve values from the attributes, tables and structures under the Output Node of the Model Node (Mn_TestModel) as usual
and store wherever in context as required. In case of output tables, you need to use FOR loop to iterate through the tables and access elements within using index (using wdContext.node<YourRequiredNode>().get<YourRequiredNode>ElementAt(int index)).
Hope it is helpful.

Open Navigation Modeler,
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.
Create 3 views with names search screen,results screen and detail screen.
Use plugs to navigate.
You can use visibility property also as another option to show/hide the views in both of these.

RE:(URGENT)WebDynpro For Java

hi all,
I have done an application in webdynpro for java that i.e accesing a java Bean by creating a model.
In my model i have taken three variables i.e a,b,c
after that i have exported the jar file of that bean...and i have created model in my webdynpro application.
in that model i have taken that jar file and i have taken in used model to....
After that in diagram view of the webdynpro componnt i have mapp that model to cntroller and from controller to the view after that i am able to use the three variables from the bean as my context attributes.....
so i have binded those attributes(from Bean) to inputfields in view layout....
so after that when i have deployed the webdynpro application the input fields are getting disabled so iam not able to give any values....
and when iam clicking the submit button the error iam getting is null pointer exception....
even i have tried with different cardinality values of that node ......but my problem was not solved so plz help me out in solving this issue as soon as possible.............

HI Mahesh,
If you have mapped variables correctly then check following
Your variables a,b,c wherever you declared them instantiate them.
and be sure that that getter setter methods are exist.
e.g if a,b,c are in your bean file then
as a = new a's class,
and check getter methods for a
i.e. getA() and setA(a's class) methods.
after this export as jar and use this new jar to create model.(It will be good if you create a new model deleting prv one)

What is Enterprise SOA and Enterprise SOA?
SOA is an increasingly popular concept. But it never really took off, because there has been no standard middleware or application programming interfaces that would allow it to take root. There were attempts to build them, then Web services came along and gave it a boost. The Web services underlying architecture dovetails perfectly with the concept of Enterprise SOA so much so, in fact, that some analysts and software makers believe that the future of Web services rests with Enterprise SOA. SAP came up with the startergic decision on coverting the Webservice methodolgy to Enterprise Services Methodology "Which would have business semantics attached as capability".
So how does EnterpriseEnterprise SOA differ from Web services?
Most Web services implementations are point-to-point, where you have an intimate knowledge of the platform to which you're connecting. The implementation is fairly solid and the interface doesn't really change,. That means that the Web service is not made available publicly on the network, and cannot be "discovered" in a sense, it's hard-coded in the point-to-point connection. In an Enterprise SOA implementation, information about the Enterprise services and how to connect to it is published in a UDDI-built directory, and so that Enterprise service can be easily discovered and used in other applications and implementations.
Why use Enterprise SOA?
A number of factors are driving the move toward Enterprise SOA. Cost savings is one. If you can reuse services you've already built, then you don't have to spend as much time and money developing new applications. Another factor is the increasing success of Web services. As companies build more Web services, unless they have an overarching architecture. For example, what happens when one of those Web services has been incorporated into other applications, but then the Web service is changed without telling developers of those applications? An overall architecture needs to be built to make sure that doesn't happen. Perhaps most importantlyis that an Enterprise SOA "increases a business's flexibility and lets it more quickly adapt to changing business needs." Most Web services are being used primarily "to solve point-to-point integration problems." But these solutions "can't solve the larger integration problems in converting hundreds of systems" to an overall, single enterprise architecture. For that, SAP Enterprise SOA is needed.
But while the basic Web services architecture fits neatly into the Enterprise concept, there are still roadblocks to setting them up. Notable among them, Is security, identity management issues, and management problems having software that will be able to track and manage hundreds or dozens of Web services and their development and deployment. SAP Software is just becoming available to do that. On the security side, the issues still haven't been solved.
Reward points if useful.

EP,ESS/MSS and webdynpro for java interview questions.

I am an ep and ESS?MSS consultant and work on webdynpro for java.I have also worked on PDK like customization of masthead and logon page.I would like to know how to prepare for an interview? I mean what should I read ? and what topics should I cover?

HI Anzar
Instead of posting this here, you could have googled it. There are no. of sites for the same thing.
Since you wrote, so just curious... EP & ESS/MSS Consultant... what does that mean?
If I am not taking it wrong, by that sentence you are trying to tell that you have worked on ESS / MSS modeule. Right?
See, if you are an EP Consultant, you must know all the below atleast -
1. PORTAL SIDE
a. Different types of iView configuration
b. User Management
c. Internal / External Portal Configuration
d. Content development
e. UWL
f. Portal bottlenecks (I mean portal related issues, like slow responding etc.)
g. Display & Desktop Configuration
h. System Landscape Directory
i. NWDI
2. WEB DYNPRO SIDE
a. Calling iviews from wd applications
b. RFC/ BAPI calls
c. JCO Connections
d. SC/DC Concept
e. Import/Export Parameters
f. Scenario Based Answering (like... if your imported BAPI import parameters are changed by BASIS, what will you do to make it work for you.... etc)
g. Singleton/Non-Singleton nodes
h. Controllers
i. Interfaces
j. Multi-lingual Applications
k. EJBs
l. PDK applications
This is the basic list, it can contain many more items... This is the list which I faced for my interview. As an EP consultant, you must be good in both Portal as well as WD end.
1 more thing, every interview is different from other, so no point in just mugging them out. Go through with there concepts. That way, you can answer twisted & scenario based questions.
Hope this will help.

Chander Kararia
if question solved, close the thread after marking it answered.

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:
