Best regards,

Hi
You can use and implement the FunctionKey UI Element in WebDynpro. Find the below link to know about that.

Charts creation with Webdynpro for Java

Hello everyone,
I am really new to SAP technologies and I have to create charts showing statistics for an application based on CE 7.1 and Webdynpro for Java.
I would like to have some inputs about the best way to achieve this, I saw it exists a business graphics UI and flash islands to use flex with webdynpro.
Thank you for your opinions

Hi Friends,
I am on Netweaver/SAP Enterprise Portal 7.0 SPstack12, I am developing UI for BI reports using VC, I am interested in developing UI using flex and want to integrate those apps with EP, I came to know flux Island supports flux with webdynpro java, basically I am a webdynpro for java developer, I want to develop flux applications with webdynpro for java in NWDS. And i want to know how to use Flex Island with webdynpro for java. So could u please post some useful links.
Thank in advance

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:

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.

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

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.

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.

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)
