Start Portal Service from EJB

hi developers,
I want to start a portal service from an ejb which runs on my portal server (this ejb is called from a r/3 system).
The portal service than has to do set km file authorizations.
Has anyone an idea how I can do this and which portal service is the best for this?
Thanx a lot

Retrieve Portal Service from EJB

Hi All,
I am trying to use a custom Portal Service from an EJB application. I assume that I have to do the JNDI lookup for the service since I can not use the usual "PortalRuntime" to get the service instance.
Looking at the JNDI browser in the Visual Admin, I can't seem to find it. I have seen some code snippets on SDN for UWLService where lookup is done via "/broker/services/XXXX.KEY"
Any insight?
Thanks,

Is there a possibility to implement a Portal Services by EJB Bean?

Let suppose we have a Portal Service class ITestPortalService and EJB called TestEJB
Can we do this in this way or any other way?
public class TestBean implements javax.ejb.SessionBean, TestPortalService

Question: Is there a possibility to implement a Portal Services by EJB Bean?
I don't think you can do this directly as the portal service is maintained and called from the irj (portal) application, while the EJB beans are called directly from the web application server (as far as I know).
The only think you could do is to have the Portal Service be a bridge, which basically only calls the EJB and returns the results.

Web service from ejb

Hi All,
I am new to java web services.
I made web services from ejb with netbeans.
I like only some people to have access to this services with user and pass stored in database.
In other words I need authentication and authorization.
How can I do this?
Regards

Well it depends also on application server you are using.
It depends also on web service stack you are using.
For example here is the hint for glassfish (Metro):

Calling portal service from web service

Hello,
I'm trying to call portal service from web service. Is this possible? I'm getting an error.
For example, code:
IJCOClientService clientService = (IJCOClientService) PortalRuntime.getRuntimeResources().getService(IJCOClientService.KEY);
.. is generating exception:
java.lang.LinkageError: Class com/sapportals/portal/prt/runtime/IPortalRuntimeResources violates loader constraints
Do anybody knows what's wrong?
Best regards,
Josef Motl

Hi Josef,
Is the IJCOClientService located on the producer side or on the consumer side?

How to call a portal service from a servlet

Hello all.
I have a functioning portal service that I would like to call from a servlet.
When I try to do so, I get a ClassCastException when I do this (on line two):
IPortalRuntimeResources runtimeResources = PortalRuntime.getRuntimeResources();
IDocumentPersistence docPer = (IDocumentPersistence) runtimeResources.getService(IDocumentPersistence.KEY);
However if I do the following I can get a generic IService and use reflection to invoke the method (in the IDocumentPersistence interface) that I want to invoke:
IPortalRuntimeResources runtimeResources = PortalRuntime.getRuntimeResources();
com.sapportals.portal.prt.service.IService aService = (com.sapportals.portal.prt.service.IService) runtimeResources.getService(IDocumentPersistence.KEY);
There must be a better way to use portal services (hopefully like scenario one above) in servlets. In web dynpro you can use portal services and cast them to the correct type. What am I missing?

Hi Kim,
how did you integrate the references to your Portal Service Interface into your web application?
You should do this using the references in your application-j2ee-engine.xml, did you do this? It might be a problem with the classloader otherwise.
The way you are calling portal services does work normally, however it is not the recommended way as it is documented in the SAP documentation.
Please check the SAP documentation on how to access a portal service from a j2ee app:
http://help.sap.com/saphelp_nw70/helpdata/EN/42/9ddd0cbb211d72e10000000a1553f6/frameset.htm

Calling a Portal Service from within a Web Dynpro DC

Hello,
I am trying to call a Portal Service from within a Web Dynpro development component without sucess.
Can anyone give me some hints on the necessary steps in order to accomplish this task?
Thanks
Diz

Hi Diz,
I tried doing the same thing by following the steps as mentioned by you. Just to re iterate,
1. Created a DC "Portal Application Standalone" project by the name myservice.
2. Created a portal service inside myservice by the ame AmitsService.
3. Exposed IAmitsService.class in the public part.
4 Build and deployed the DC on server and tested it through an abstract portal component and it worked FINE !!
Now..
5. Created anoter DC of type WebDynPro
6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
7. Specified the sharing reference in the properties as PORTAL:sap.com/myservice
8. Tried to reference the service using the following code..
IAmitsService portalservice=(IAmitsService)WDPortalUtils.getServiceReference(IAmitsService.KEY);
9.Build and deployed the DC.
10. When I run the application I am getting the following error
Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sapportals/portal/prt/service/IService
Exception id: [000D6008418B005C0000002C00000D200004163CE6719E1D]

Unable to start obiee services from "Services"

Can somebody please help me with this.

Hi,
Regarding the Java Service have you installed the Java JDK (can be found here ) in a directory that contains no spaces?
Installing it in Program Files will cause issues so perhaps reinstall it into a location like C:/Java/jdk1.6/
After installing it to the new location you will need to update the instanceconfig.xml file (mine is located C:\OracleBIData\web\config\instanceconfig.xml).
Change the location of the Java Home between these tags to the root of your newly installed Java sdk. eg <JavaHome>C:/Java/jdk1.6</JavaHome>
Try launching the service again.
Let me know if this works or doesn't,
J

Accessing custom Portal service from a java application

We have a custom portal service that connects to BW using xmla. How do you access this portal service from a java application. Not from web dynpro, jsp or servlet but from the java code.
Can we use the INITIAL_CONTEXT_FACTORY to get access to the portal service.
Thank You
D.K

Now I tried the following:
I've added the prtapi.jar and the service's jar to the additional-lib folder and added the appropriate entries to library.txt and reference.txt.
Now I can obtain now the PortalRuntime, but this is not initialized.
Has anybody a solution for this problem? Help would be high appreciated!

Matthias

I can't start OLAP Service from OEM 9.0.2

I don't know how start Olap Service from OEM 9.0.2. Please tell me how to do this! May be somebody will send me letter. [email protected]

Yes.
First, get an app called MPEG Streamclip, which is free. (google MPEG Streamclip from Squared 5)
Open MPEG Streamclip.
In iMovie, select the clip you need. Then, right-click/Reveal in Finder.
Drag this clip into MPEG Streamclip
In MPEG Streamclip, move the playhead to the frame you want.
In MPEG Streamclip, click FILE/EXPORT FRAME.
Choose JPEG, TIFF, or PNG and give it a name.
You can then drag this photo into iPhoto.
Here is a video I made that steps through this...

Consume Portal Service from J2EE web application

hi, i am a newbie to portal content development. My team have developed a J2EE web application to be run on the portal. Is it possible to consume a Portal Service from J2EE web application? If possible, deeply appreciate if you could provide some guidelines. Kindly advise. Thanks.

Hi Theodore Yu,
You need to expose your portal service as a webservice to consume it in a j2ee web application.
For exposing a portal service to webservice check this link
