Portal integration: Navigation from Web Dynpro to other iviews

Hello,
I am trying to implement a navigation from my web dynpro application (which is embedded in our corporate Netweaver portal) to another portal iview.
Therefor I use the "absolute navigation" functionality:
CALL METHOD lo_portal_manager->navigate_absolute
EXPORTING
navigation_target = 'pcd:portal_content/BOSCH_CONTENT/INTERNAL/CONTENT/MY_WORK/MANAGEMENT_SUPPORT/ORDERINGS/PAGES/rb.inside.page.EWORKS_PROCUREMENT'
By hitting a button in the web dynpro this functionality is executed but nothing happens.
The iview defined as target is not called.
The SAP documentation (http://help.sap.com/saphelp_nw70/helpdata/de/18/f96f4132f15c58e10000000a1550b0/frameset.htm) says, the "Absolute address, path for page or iView in the portal content directory. " should be defined as target.
Address, for example ROLES://portal_content/...
I also copied the address from the portal content directory, but it always starts with "pcd:portal_content" and not with "ROLES://portal_content/".
Is this an issue of the portal or of the method call?
Thank you a lot in advance...
Regards
Stefan Löhlein

Hi,
1.first check if popup blokcer is is disabled for the portal url you are testing with.(This is asuming you are navigating to the iview as an external window).
2.Make sure you are testing this in the context of portal .ie you are runnning the web dynpro within portal and not outside portal as an application.
3.The iview that you would be prefixing with ROLES:// should have the permissions set for the user you are testing with.

Ashok

Accessing portal dictionary tables from Web Dynpro project

Hi
Am a new to whole portal and webdynpro thing, and I hope that you can help here
I created a new dictionary project through NWDS and created a table with columns and I successfully deployed it
I also created a web dynpro project and I added a TABEL UI to the layout
how can I connect or access the table I created in the dictionary project from the Web dynpro project so I can query all data to fill the TABEL UI in the web dynpro ?
is there a driver that I can use like JDBC where I can just write regular SQL queries ?

Change portal Page layout from Web Dynpro

I have some problem:
I need to rearrange Portal Page layout from 2 columns to 1 collumn from Dynpro action. Decision to hide 1 Column or resize its width to 0 is good idea, but I do not now how.
Absolute Navigation is wrong idea, because I need to go back to multiply IViews mode and I will lost my data context.
I saw PageService - custom Portal service, where I can resize IViews.
In my Netweaver 2004 this class is absent.
Probably exist some Portal events to manage Page layout? Anybody knows?
Thanks!

Hi,
For this we have to use eventing among the webdynpro components of two different views.You can refer this example for this.

Navigate from Web Dynpro app to portal page

Dear All,
I've created a number of Web Dynpro applications which I run from various portal pages. From one of the Web Dynpro's I navigate to a different portal page using the WDPortalNavigation.navigateAbsolute method. This works fine, but I'm left with one problem:
I'd like to pass parameters from the Web Dynpro which navigates to the portal page to the Web Dynpro applications which run on that specific page. I've appended the parameters to the URL I'm navigating to (eg ROLES://<pcd location>?<param=xxx>) and in the Web Dynpro's I've added a parameter to the Default interface plug. This doesn't seem to work. As an alternative I've added the statement WDWebContextAdapter.getWebContextAdapter().getRequestParameter("param") to the doInit() method of the view, but this also doesn't work.
Either I'm doing something wrong, or what I want to accomplish is not possible. Does anybody know of a way to access parameters passed to a portal page from Web Dynpro applications contained on that page?
Thanks,
Arnoud

I hope you are passing parameters between two WebDynpro applications.
Please go through the example available for passing interaction between two webdynpro components.
Please check the following link
Alternative method for navigating to another page ?

Portal dynamic iView from Web Dynpro ABAP?

I wish to use a "Dynamic iView" from a Web Dynpro ABAP application, but it appears the API is only available in Web Dynpro Java. Can this feature be used from Web Dynpro ABAP, or can this be accomplished in another way?
Scenario: I have two iViews on a page, one Web Dynpro ABAP and another iView whose source I want to change dynamically based on something a user clicks in the Web Dynpro ABAP.
Dynamic iView:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/a72c155df77038e10000000a422035/frameset.htm

So you are suggesting the WDA fires an event to a new WDJ that we would need to create that would in turn use the Dynamic iView service mentioned in that help document?

Accessing Portal Service from web dynpro : NoClassDefFoundError

Hello Experts,
I tried to develop a portal service (EquiService) and a web dynpro application (wdequset) which accesses the portal service. I put my web dynpro in an IView to show it in the portal. The service is running but when I try to open the IView I always get an error. I debugged my web dynpro application and found out that I didnt get a reference to the service (portalEquiService is always null). See the following code and have a look to my comments.
public void wdDoInit()
    //@@begin wdDoInit()
    String key = IEquiService.KEY;
     * Here I get the right key. Thats OK so far.
//    IEquiService portalEquiService = (IEquiService)PortalRuntime.getRuntimeResources().getService(key);
     * When I use this line to get an instance of the service, I get the following error:
     * java.lang.NoClassDefFoundError: com/sapportals/portal/prt/runtime/PortalRuntime
     * The package "com.sapportals.portal.prt.runtime.*" is imported
     IEquiService portalEquiService = (IEquiService) WDPortalUtils.getServiceReference(key);
      * I found this in the "How to Access a Portal Service Within a WebDynpro Java Application" document.
      * When I use this line, I get the following error:
      * java.lang.NoClassDefFoundError: com/company/service/equi/IEquiService
      * The package "com.company.service.equi.IEquiService" is also imported.
    wdContext.currentContextElement().setEquinummer(portalEquiService.getEquiData().getEquiNr());
    //@@end
When I have a look to the service in the portal I see that the service is running and the following additional lines under Dependents:
service: psequinr|EquiService
SAPJ2EE::company.com/wdequset
So the service seems to know my web dynpro application (after debugging for the first time).

The prtapi.jar is set in the classpath:
<classpathentry kind="lib" path="C:/Programme/SAP/JDT/eclipse/plugins/com.sap.tc.ap/comp/SAP_JTECHS/DCs/sap.com/epbc.prtapi._api/_comp/gen/default/public/default/lib/java/prtapi.jar"/>
and when I look in the portal (System Administration -> Support -> Portal Runtime -> Application Console), select my service and press the "show" Button, I see that the service has a dependency to my web dynpro application.
service: psequinr|EquiService
SAPJ2EE::company.com/wdequset
So I think that the sharing reference of the web Dynpro should be ok. Or not?

How to get the Response Code when a URL is launched from Web Dynpro

Hello Experts,
I have a Web Dynpro Application in which in one of its views i have an IFrame UI element in which i will show a resource stored somewhere ..
But before showing it i want to check if the resource actually exists. For this i have to check the HTTP Response code from Web Dynpro Application without setting it in the Iframe..
I am using the following code to get the Response Code:
try{
URL url = new URL("Some Url");
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();
wdComponentAPI.getMessageManager().reportSuccess("Response code ="+connection.getResponseCode());
}catch(Exception e){
wdComponentAPI.getMessageManager().reportSuccess("Exception");
Now the Problem is whatever response Code occurs 403 (for No Proper Authorization), 404 (for Resource not found) etc..
i always get Response Code= 500 (which is for Internal Server Error) shown in the messgae i have printed.
Please let me know the correct way of getting the Response Code from Web Dynpro.
Also my resource is lying on a SAP Portal 6.4
Best Regards

CAF DB Update for CAF Entity Service from Web Dynpro

Hi all,
I have created an entity service in CAF called Contacts which contains the following attributes.
phoneNo
cellNo
emailID.
Another entity service called "Person" is created. This contains the following attributes.
personId
personName
personAddr
contactsRef. (Cardinality -> 0..n , Relational Type -> Composition)
That means Contacts entity service is used within Person entity service. Now it is working fine within CAF service browser. Now the Web Dynpro DC of CAF application is used within another custom Web Dynpro DC project. I want to store data from Web Dynpro.
Within the context of component controller of Web Dynpro the structure is like
APerson
     |_ personId
     |_ personName
     |_ personAddr
     |_ contactsRef
                |_ phoneNo (Under contactsRef)
                |_ cellNo (Under contactsRef)
                |_ emailID (Under contactsRef)
So I have written the following code within web dynpro custom method.
APerson person = PersonServiceProxy.create();
java.util.List ls = new ArrayList();
for(int i=0; i<4;i++)
AContacts contact = ContactsServiceProxy.create();
contact.setCellNo("9092130156");
contact.setEmailID("[email protected]");
contact.setPhoneNo("432258");
contact.getAspect().sendChanges();
ls.add(contact);
person.setRelatedModelObjects("contactsRef",ls);
person.setPersonID("9999");
person.setPersonName("xyz");
person.setPersonAddr("ABC, KOL");
wdContext.nodeAPerson().bind(person);
person.getAspect().sendChanges();
CAFServiceFactory.getServiceFacade(idendityDefinition.class);
After saving the data from Web Dynpro I am trying to test it from CAF service browser. But I am getting only the parent row. I mean only the value of personId, personName and personAddr fields which I have stored from Web Dynpro. But no value is coming within the table for Contacts entity service for composition relation.
Could anybody help me how can I solve my problem?
Thanks & Regards

Hi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.

Connecting to SAP from Web Dynpro

Hi,
I am new to web dynpro, but have downloaded the java sneak preview edition and worked through it a bit. I understand that we have to use JCo to connect to SAP from Java Web dynpro, . Is it true?
What about web dynpro for ABAP? Can we use normal select statements to connect to SAP? How is it exactly done in that case?
Thanks in advance
PG

hi pg
Just go thru this example which describes how to connect to SAP from web dynpro application.

Using Portal Theme for a Web Dynpro ABAP Application

Hello everyone,
I've created a web-dynpro abap application that I display on one of my portal pages using a Web-dynpro iView.
Somehow, the WDA app never reads the portal theme properties and has the default SAP roadshow theme colors. I've tried almost everything including passing the theme as an application parameter using WDTHEMEROOT and WDFORCEEXTERNALSTYLESHEET params.
Documentation states that the application should automatically read the portal's theme, but it never does.
Interestingly, I have one more web-dynpro java application that works fine and uses the portal theme correctly.
Am I missing anything? Are there special considerations for WDA apps to adapt to the current portal theme?
Any ideas, suggestions, solutions would be greatly appreciated.

>Am I missing anything? Are there special considerations for WDA apps to adapt to the current portal theme?
What are the release and support package levels of both your ABAP system and your portal? If the ABAP AS has a later release or SP level than the portal, the Web Dynpro framework will always fall back to using the theme of the backend ABAP system. This is to protect the application rendering. Running with a theme (CSS and JavaScript) from an older release or support package level could cause the application to render incorrectly.

Set Portal Page URL in Web Dynpro IFrame

Hi All,
I've a Web Dynpro application that runs in the portal.
The application creates iframes dynamically.
I want to set in the iframes portal pages.
In order to get the page's url, I go to content admin, navigate to the page and then press the 'preview' button then I copy the url from the browser's address bar.
I copy the url from the '/irj....' to the src property of the IFrame UI element.
So the source property looks something like this:
/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.mycomp.Omri!2fcom.mycomp.TestPage
When I run the project I get:
<i>Portal Runtime Error
An exception occurred while processing a request for :
iView : N/A
Component Name : N/A
Access denied (Object: portal_content/.../...).
Exception id: 06:01_17/10/06_0015_4401150
See the details for the exception ID in the log file</i>
The page's permissions are set to everyone so I don't know why do I get this error.
So, how do I set portal page url in Web Dynpro IFrame?
p.s
I tried to use NavigatinTarget in the URL and it works. The problem is that the TLN is included. I want to display only the page.
Thanks,
Omri

Hi Valery,
I have only one domain...
I searched SDN and I found this post:
/message/1259616#1259616 [original link is broken]
Daniel Wroblewski from SAP says:
<i>This, naturally, sounds like a permission issue. Two steps:
You must give the Everyone group end-user permission to the iView. This will eliminate the error and cause a login screen to display.
If you want to eliminate the login screen, you must set the iView property Authentication Scheme to anonymous.</i>
I will try it tomorrow in the Office.

CAF DB update from Web Dynpro

Hi all,
I have created an entity service in CAF called Contacts which contains the following attributes.
phoneNo
cellNo
emailId.
Another entity service called "Person" is created. This contains the following attributes.
personId
personName
personAddr
contactsRef. (Cardinality -> 0..n , Relational Type -> Composition)
That means Contacts entity service is used within Person entity service. Now it is working fine within CAF service browser. Now the Web Dynpro DC of CAF application is used within another custom Web Dynpro DC project. I want to store data from Web Dynpro. So I have written the following code within web dynpro custom method.
APerson person = PersonServiceProxy.create();
     java.util.List ls = new ArrayList();
    for(int i=0; i<4;i++)
    AContacts contact = ContactsServiceProxy.create();
     contact.setCellNo("9092130156");
     contact.setEmailID("[email protected]");
     contact.setPhoneNo("432258");
     contact.getAspect().sendChanges();
    ls.add(contact);
     person.setRelatedModelObjects("contactRef",ls);
     person.setPersonID("9999");
     person.setPersonName("xyz");
     person.setPersonAddr("ABC, KOL");
     wdContext.nodeAPerson().bind(person);
     person.getAspect().sendChanges();
     CAFServiceFactory.getServiceFacade(idendityDefinition.class);
After saving the data from Web Dynpro I am trying to test it from CAF service browser. But I am getting only the parent row. I mean only the value of personId, personName and personAddr fields which I have stored from Web Dynpro. But no value is coming within the table for Contacts entity service for composition relation.
Could anybody help me how can I solve my problem?
Thanks & Regards
Chandan

Hi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.

Calling Remote-Enabled JAVA Module from Web Dynpro Java

Anyone have a clue how I can call a Remote-Enabled JAVA Module in ECC from a Web Dynpro Java app? I'm on Portal 7.0. When I try and create an Adaptive RFC model in NWDS and put in the Function Module name (CFG_API_FIND_KNOWLEDGEBASES) or its Function group, that RFC is not returned for me to import. Can I not use this method to get at this function?
(I CAN call this function module and run it from the old SAP Business Connector software. That, however, does not help me get it into my Web Dynpro app.)

If anyone stumbles upon this thread, the long and short answer is you can't call a Remote-Enabled JAVA module in SAP from Web Dynpro Java.....using Adaptive RFC.
You can, however, if you create your own session and function call directly in Java code and give up on being able to use Adaptive RFC.
