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.
<b>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.?</b>
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.

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?

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.
is it right choice i am taking ? i.e moving to Webdynrpo 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,

Dibya

Hi
What exectly you want to check(is there any letter drafting / mail functionality in wd dynpro ?)
Webdynpro itself doesn't have this feature but you can try a workaround .
1. Use API in External Library project ([Spell check API|http://sourceforge.net/projects/jazzy]).
2. use this DC in WD component , now when ever user writes , iinvolve this API's method to check.
(Its a workaround you have to to the R & D).

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:

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.

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
