Refer Portal service in EP7.3

Hello all,
step 1 : migrated Portal service par 7.0 to 7.3 Dc (susezp/scsusezp/dc_portalservice_ear) by using Portal Dcs under track added required code.
step2 :migrated portal component par 7.0 to 7.3 Dc (susezp/scsusezp/dc_s2p_announcement_ear) by using Portal Dcs under track added required code.
portal service DC added under dependencies of portal component DC.
now i have deployed portal component getting below error :
Caused by: com.sap.engine.services.servlets_jsp.server.deploy.impl.exceptions.WCEApplicationNotStartedException: The application [pg.com/susezp~scsusezp~dc_s2p_announcement_ear] is configured to have ALWAYS start up mode. Currently it is in STOPPED status - because of this it will not be started implicitly by the Web Container service and any internal operation that needed this application to be running will fail. The reason for STOPPED status is because the application failed to start during cluster startup. The error is: 5625350
startApp
2
Application pg.com/susezp~scsusezp~dc_s2p_announcement_ear cannot be started. Reason: it has hard reference to the following resources, which are currently not available on the system: hard to SAPPORTAL/pg_portal_service_ear (public) (f=true, cl=true); .
In order to start the application, components that provide the missing resources should be successfully deployed.
it is showing portal service in stopped but if saw in NWA java application portal service is showing status as started.

Is the reference you are using (SAPPORTAL/pg_portal_service_ear) right for sure? It looks your service has another one, since EP cant find it
cheers

Hi Mukesh,
Please refer to the document

How to acces portal services in webdynpro

Hi I want to access portal services from webdynpro, i red that for that we have to provide sharing reference in webdynpro application. which will be
PORTAL :< Vendor name>/<Full qualified name of the portal service>
my question is how to find out vendor name and Full qualified name of the portal service from par

Hi,
Web Dynpro applications can access portal services in one of the following ways:
●      Directly: The application can get an instance of the service on the machine on which the Web Dynpro application is running.
●      Via the Service Factory: The application can request an instance of the service from the service factory. The service factory provides a conduit to portal services to ensure that the proper service is called, even in cases when the Web Dynpro application and the portal are running on different machines.
Only services written in a remote-safe manner are available via the service factory. These services include the following portal services:
Page Service
Tray Service
Page Service
The page service provides information about the page in which the application is running, and enables you to perform the following tasks:
●      Getting a list of the atomic names of the visible iViews in the page.
You may want to use this method to avoid updating the user interface of an iView when it is not visible.
IWDPageService pageService = (IWDPageService)
    WDPortalUtils.getService(WDPortalServiceType.PAGE_SERVICE);
// String array receives iView names
String[] iViews = pageService.getVisibleIViews();
●      Hiding/showing iViews in the page
IWDPageService pageService = (IWDPageService)
    WDPortalUtils.getService(WDPortalServiceType.PAGE_SERVICE);
// display iView Search
pageService.showIView("Search");
// hide iView Details
pageService.hideIView("Details");
Changes to the visibility of iViews are not saved. When a user refreshes the page, the original settings are restored.
Tray Service
The tray service enables you to add a menu item to an iView or page tray, and to specify a Web Dynpro action to execute when the menu item is selected.
The following is an example of adding an iView and page menu item:
IWDTrayService trayService = (IWDTrayService)
    WDPortalUtils.getService(WDPortalServiceType.TRAY_SERVICE);
if (trayService != null) {
    // Add iView tray menu item
    trayService.addIViewItem("addItemComment", "Add Comment",
    wdThis.wdGetAddItemCommentAction(), null);
    // Add page tray menu item
    trayService.addPageItem("addItemComment", "Add Comment",
    wdThis.wdGetAddItemCommentAction(), null);
Generally, tray menu items are added in the wdDoModifyView() method. Make sure to add the menu item once; otherwise, duplicate menu items are displayed.
Procedure
This section describes how to call a portal service.
For services whose interfaces are provided by Web Dynpro (such as IWDPageService and IWDTrayService), you do not need to perform Steps 1 and 2.
       1.      Make a sharing reference to the service, by doing the following:
                            a.      Right-click the Web Dynpro development component or Web Dynpro project, and select Properties.
The Properties dialog box opens.
                            b.      From the left pane, select Web Dynpro References.
                            c.      In the Sharing references tab, add a reference to the portal service with the following format:
PORTAL:<Vendor name>/<Fully qualified name of the portal service application>
For example, the following shows a reference to the navigation service:
This graphic is explained in the accompanying text
       2.      To build the project, add the JAR file containing the service to the classpath of the project in the IDE.
Do not store the JAR file of the service in the libfolder of your development component or Eclipse project. This causes classloader problems at runtime.
       3.      Get an instance of the service.
To call a portal service directly, without the service factory, call WDPortalUtils.getServiceReference() with the key for the service, as in the following example:
IUserObjectBasedNavigation obnService = (IUserObjectBasedNavigation)
    WDPortalUtils.getServiceReference(IUserObjectBasedNavigation.KEY);
To call a portal service via the service factory, call WDPortalUtils.getService() with the WDPortalServiceType constant for the service, as in the following example:
INavigationService navService = (INavigationService)
    WDPortalUtils.getService(WDPortalServiceType.NAVIGATION)
If more than one Web Dynpro controller needs to use the same portal service, you can store the portal service reference in a controller context node. All other controllers that need to use the service must define a context node and map it to the context node with the service reference.
A portal service can be called only when the portal platform and the Web Dynpro application are running on the same machine.
It is recommended not to use your Web Dynpro-based portal content in a global or federated portal scenario.

Trouble creating a portal service

Hi,
We are trying to create a portal service with the DeveloperStudio (7.1) and are having lots of problems. We are creating the project with the "Portal Application Project" and then creating the service via "Portal Application Object". This worked well in the old 7.0 environment.
We can find the services via nwa and it says there that they are running but we have no indication that they have really started, because the functionality isn't be used. The logger is not being fired either.
Checking the traces we are finding strange warnings like "Web Model Builder: WEB-INF/web.xml is not Java EE 5 compatible, because of this annotations will not be processed." or "BcaClassFinder.addResources Can not open zip fileD:\usr\sap\CE1\J00\j2ee\cluster\server0\temp\deploy\work\deploying\TestServices.ear1215787665722\META-INF\sda-dd.xml it is not a valid zip archive"
We created another service without any code from us and we are still getting strange errors.
We also changed the permissions for the service to "Everyone" and this still didn't help.
Our functionality can be packed in some other sort of service - it doesn't have to a portal service. The main requirement is that the service is restarted after a server restart.
Does anyone have a clue what the problem might be or what sort of a service might be more appropriate?
Thanks.

Fully qualified name of the portal service application

Hi,
I want to Access portal Services from Web dynpro, for Which we have to provide Sharing reference,
this would be
PORTAL:<Vendor name>/<Fully qualified name of the portal service application>
my question is how to find out "Fully qualified name of the portal service application"
regards,
Venki.

Venki,
Please refer this thread.
Re: Changes are not getting reflected in theme
We cannot access the portal service in the browser as the service wont produce any http request. Instead you can access & utilize the service in the the portal component such as JSP Dunpage etc. which will produce the http request and display the result or o/p on the broswer.

How to log exceptions and imp logging info in Portal Service via ILogger?

Hi Experts,
I m trying to use ILogger for my application.
Information about my application:
I have created a Portal Service and exposed it as a Web Service which is deployed as a PAR file on to the SAP J2EE Engine.
I need to use the Logging facility of ILogger in this Portal Service.
I have written the following code in the Init() function of the Portal Service
public void init(IServiceContext serviceContext)
mm_logger = serviceContext.getLogger("com.persistent.pankaj");
I have put the logger.xml in the logger folder of PORTAL-INF
my logger.xml is as follows:
<Server>
<Logger name="testLog" loggerInterface="com.sapportals.portal.prt.logger.ILogger" locationName="com.sap.portal.testLog" pattern="%d # %20t %15s %m #" isActive="true">
<LoggerClass className="com.sapportals.portal.prt.logger.SimpleFileLogger" level="INFO">
<param filename="logs/com.persistent.pankaj.log" append="true">
</param>
</LoggerClass>
</Logger>
</Server>
On deploying my portal service as a web service
I m unable to get the logs.
I even dont know where will i get the log file, means wat is the exact location where i can check my log results
I m a newbie for this
Please help me out
Help will be rewarded n appreciated
-pankaj

Hi Pankaj,
In your init method try this code to create the logger:
ILogger logger = PortalRuntime.getLogger("testLog");
In your logger.xml the logger name was testLog and not com.persistent.pankaj so while creating logger you should use testLog in the above code.
By default all the logs are written to defaultTrace.log files, to check them read this:
Portal Runtime Logs
If you want to log in a seperate logfile then you should set a seperate log destination, which is not recommended on productive systems due to performance problems.
Also read these to know how to set seperate log destinations:

Error during startup of portal service after SPS11

Hi Guys,
After installation of SPS11 to our 2004s portal system we have problem with startup of our Portal service.
Before SPS11 we had SPS9 system and everything was working correctly.
Our service is connecting to Database during its initialization.
This is part of our code:
Properties p = new Properties();
p.put("java.naming.factory.initial", "com.sap.engine.services.jndi.InitialContextFactoryImpl");
try
     Context ctx = new InitialContext(p);
     _ds = (DataSource)ctx.lookup(POOLNAME);
     Connection conn = _ds.getConnection();
     conn.close();
     LogWriter.traceInfo(LogWrapper.trace,"Connection established.");
} catch (NamingException ex)
The error is:

The probleam appears only during startup of portal!
If you deploy service on running portal it is started without any problems.
We tried to apply note (Note 960199 - 2-Phase Init Mechanism for Portal Services is Deprecated) but without success.
This is modification of our portalapps.xml as described in Note.
    <service name="StatemanagementLogService">
      <service-config>
        <property name="className" value="cz.sap.statemanagement.StatemanagementLogService"/>
        <property name="startup" value="true"/>
        <property name="twophaseinit" value="always"/>
      </service-config>
Please could you help us with this problem?
Anyone has an idea what is wrong?
Thanks a lot
Ondrej

Hi Nirmal,
thanks you for your quick response. This is what the installer returns when I use your suggested command:
Mar 7, 2012 2:35:56 PM [Error]: The parameter jce_policy_zip in externally supplied configuration is invalid.
I looked up the parameters for the STARTUP:
rootdir [guiport] [httpport] [guistart] [guimode] [config] [sid] [instanceNr]
Thus the jce_policy_zip is not a valid parameter.
However, after deleting the file specified I could just run STARTUP again and this worked.
Thanks
Marcel

Get current user in portal service context

hi guys,
We want to implement a portal service which will check user's role from LDAP, and we need to get the current user id.
We know for class IPortalComponentRequest, there is method getUser().getUserId(), is there any similar method for IServiceContext? or any way for us to get user id in portal service?
regards,
Guo Feng

Hi Feng,
Implement
public String getParameter(IPortalComponentRequest arg0, String arg1)
eg in your implementation class and add the following code.
IUserContext userContext = arg0.getUser();
String username = userContext.getLogonUid();
String full_name = userContext.getDisplayName();

Consuming a webservice from a portal service...

Hello all,
I am playing around with the example code for imlimenting a federated search (found in the km section) and was trying to use a webservice call to google as an example of a the federated search.
I generated a client side portal service (from the goodle wsdl) and I am now trying to access it form the search virtual index service I wrote...
I someone can point me in the correct direction that would be great... I was looking at the following blog Accessing an External Web Services in Portal which helped setup the webservice but I find the code used to access it does not help. For one thing I can not find the IServiceName class anywhere in the portal or j2ee javadoc or jat files.
Cheers,
D.

Hi ,
I am getting the problems while consuming the web services in portal component.
I am not able to call the methods of web services.
look at my code.
IListServiceName client=
(IListServiceName) PortalRuntime.getRuntimeResources ().getService (IListServiceName.KEY);
GetListResponse glr= client.getList();
frist line is working fine.
In my web service i have a method called GetList().
Any way i have to call that method and get the result.
But there are other classes which are automatically generated when i consumed the web service, like GetListResponse().
When i try to call client.GetList(); it gives the error at run time, No error in the code but the errors are coming at run time.
Where is the problem? other things like proxy settings, etc i have done.
What could be the problem? Can any one suggest.
Regards
Bala
