URL iView vs WSRP

Hi all,
I was wondering what the advantage of proxy-to portlet WSRP iViews versus URL iViews would be.
In other words, suppose we've got a portlet running on a non-SAP producer. Why would we want to WSRP it instead of creating a URL iView referencing it?
Thank you in advance.
Marco

WSRP allows sharing of portlets (iViews) between SAP and
non-SAP portals
Runtime execution of portlets remains on the WSRP producer
Consuming WSRP Content
Any WSRP producer can offer portlets to an SAP NetWeaver
consumer
The SAP consumer can integrate remote portlets into local
content as standard iViews
Producing WSRP Content
Customers and partners are able to develop Java-based iViews
and make them available for WSRP consumption
The WSRP standard provides support for integration on a generic
portlet level only

SSO to BW reports via URL iView

Hi all,
I've searched the forum on this but could not get a clear guide. Here's my scenario:
1. We use Windows logon credentials to sign on to the Enterprise Portal
2. Once signed in, authorized users load a URL iView.
3. The iView contains URL links to SAP BW reports.
4. Based on user's role, they can access only certain reports.(Available report URLs will be different)
5. User clicks on the link and opens another Internet Explorer window to show the BW report without signing on again.
Key question: How do we incorporate the SAP Logon Ticket into the URL and how do we configure BW server to accept SSO based on this URL?
Any help is much appreciated. Thanks!

Hi Kok,
The first step is you need to create a system object under system administration --> system configuration --> system landscape. Expand the portal_content. Right click the folder and create a new folder. Then right click on the folder to create a new system. This system object should point towards the BW system. You need to give the details of the BW server. The right click the system object and create an alias.
If you are using BW 3.5, you need to follow the 13 steps given under img. If BW version < 3.5 then you have to export the portal ticket to BW and BW ticket to EP.

Problem with URL iView regarding fetch mode and SSO to non-sap webapps

Hi,
I have created an URL iView which opens an internal webapp. When the fetch mode is set to client-side the page is displayed for the user. But when I set the fetch mode to server-side, the page cannot be displayed by the user.
No proxy is needed. I tried to open the wepapp direcly on the portal server without any problem. Are there any additional points to be considered?
On the other hand I want to realize SSO to this webapp (form based authentication) with user mapping. Is it correct, that I have to user server-side fetch mode, when I want to use the POST request method?
Thanks ahead,
Bernd

Yes.

Have a look at System Administration - System Configuration - Service Configuration - Applications - com.sap.portal.ivs.httpservice
This is used to do the Server side fetch.

How to change the URL of a URL-iView over Code ?

Hi all,
i am getting started with the Portal-Application-Developement and want to change the URL of an URL-iView on runtime with java-code.
i have read the context and can get the Property url with this statement.
endContext.getProfile().getProperty("url")
But if i change this property, nothing is done.
endContext.getProfile().setProperty("url", "http://www.yahoo.com");
Where is my fault.
Thanks for help.
Regards Jürgen

Hi,
the context is of Type IPortalComponentContext.
I cant find no method getParameter() at the context or the profile.
The methods to read the properties of the URL-iView are
context.getProfile().getProperty("url")
context.getProfile().getAttributeValue("url")
But if i want to set (change) this attribute, nothing is done.

How to pass SSO Login Ticket to an URL iView

Hello experts,
We have an application running on Netweaver and it is setup to accept SSO Login Tickets for authorisation.
I have the following question:
We want to expose some of the portlets in our application in a portal page using URL iViews, but we don't know, how to setup this environment, so for each iView, the SSO Login ticket is passed to the portlet of our application (this way access to it can be granted)?
How can we achive this? Or, is there another approach for this scenario?

Hi Megha,
The portlets are part of our application which is deployed on the same Netweaver App server as is the Portal.
When the user log in into the Portal - SSO Tiket is being issued and we want this ticket to be passed to the URL of the URL iView, but currently HTTP 401 error is returned or HTTP Basic authentication login popup is displayed. We want to be able to use the SSO Ticket for this purpose.

Georgi

Problem with JavaScript in URL iView

Hi,
I am facing a problem with javascript when i am trying to access my application through URL iView. In the javascript window.top is used to access the frames in the window. But the EP is not recognizing it as valid. what exctly the problem and please suggest me a solution.
Ashok.

Hi,,
thanks for the quick reply. But what i asked was different. I will put it in different way. I have deployed a application in Web Application Server and trying to access it through URL iView. My application is pure J2EE application with html,jsp and JS files. In javascript we used window.top property of the java script which is working fine MS IE. The problem is window.top is a IE specific property which is not having any equallent open standerd so EP is throwing a java script error. As I know the only possible solution for this problem is inherating IE rendaring capabilities to iView(i.e iFrame). is there any way to do that?

URL iView doesn't open link in new window

Hi All,
I'm have an URL iView that I want to display in the portal content area but whenever the user clicks on a hyperlink on that iView launch a new window for the link.
I've tried using the 'Open iView links in new window' without any success. Is this supposed to work or this property is for another purpose...? Can someone point me to a solution.
Thanks

Hi Detlev,
I checked what you said. I've already looked at that page but didn't saw that important disclaimer. My problem was that I didn't had a captured area-URL iView but a full page-URL iView as it says:
+These properties are relevant in the following instances only:
§ The iView content is displayed in its source format. The rendering type must be defined as Keep Source Formatting. See Defining the Look and Feel of the iView Content.
§ The iView content displays a captured area, and not the entire Web page. See Selecting the Capture Area.+
I only had to change the 'Open iView links in new window' to Yes after capturing a part of my page and it started working.
Thanks for sharing

Open web page from URL iview in maximized window

Hi,
I would like to open a web page in a maximized browser window, using an URL iView.
I know how to open a window in a separate window, I just can't get it maximized.
N.B. I do NOT want to open in fullscreen mode, i.e. I want a title bar and menus.
Does anyone know how to do it?
I tried to play around with the "window function" property of the iView, but no luck so far. I can't specify a fixed width and height of the target window at design time, as these values may vary at runtime.
regards
Lothar

Hi Lothar,
Yes, That will require Java Coding, Its true. Basically what the problem here is that to maximize we are trying to fetch the Screen resolution dynamically through Portal that Portal is not allowing us. Thats why I feel that we should go for Java Programing, Create a Par, Deploy it in the server and then create iView for that.
For Creating the Abstract Portal Component for Opening a Maximized Window You should do following steps.
1. Open Your NWDS
2. Create a project ie Portal Application
3. Create Portal Object ie Abstract Portal Component.
Now here is the piece of code that may help you
 response.write("<SCRIPT language=javascript>");
 response.write("function onOpenWindow()");
 response.write("{");
 response.write("window.open('http://abc.com','windowName','width=screen.availWidth,height=screen.availHeight,resizable=yes')");
 response.write("}");
 response.write("</SCRIPT>");
 response.write("<a href = \"javascript:onOpenWindow()\">abc.com</a>");
Paste this code in doContent...
I think it may help you
Thanx & Regards

Difference: SAP BW Report iview - Query iView - URL iView

Hi,
I want to show BW reports on the portal. Can anybody suggest me the different ways of doing it ? And also let me know about checklist of steps that need to be performed.
Can anybody tell me the difference between showing BW reports through URL iviews, showing reports through Query iView and showing reports through SAP BW Report iView ?
Which one can i use for showing BW reports taking into consideration the implementation of SSO between the two? I tried the URL iView (using the Web URL of reports generated by BW) but it asks for Username/password. Is that the problem with SSO. How can i check if SSO parameters have been set or not. I have imported the verify.der to BW System and added that to ACL. Is there anything else which is required?
Thanks in advance.
Rgds,
MA

Hi Manoj,
I feel BW report iview will solve your problem. You can create a query sting in BW query designer and give the same in BW query string text area while creating BW report iview.
In the case of an url iview you are just giving a URL link of the BW report (this will ask for username/password).
But, in the case of a BW report iview you can view the required query as an iview (user mapping can be successfully done in this case) You should give fully qualified domain name in Was server option while creating the system.
While using the logon ticket Login id of both the system (ie BW and Portal) should be the same.
Refer the link for SSO using logon ticket)

Print BW report embedded via URL Iview

Hi,
We have a VC application which contains a BI report. In the VC we created a "Print" button which should print the entire contents of the VC Application. Unfortunately it seems this print is not compatible with the URL Iview since it ignores the content of the BI report.
Is this normal ? Is there a workaround available in VC to print a BI Web application via the VC ?
thanks

Please let us know if there are any updates on this. I am also facing the same issue where I have a WAD report ( html link) in the VC model along with other reports in VC. The Print screen just prints the VC part and the WAD part comes as blank.

Remove Scroll bars in a URL iView

hi
I am attaching more than one( three or four) URL iview to a page and while opening the page, I don't want the Scroll bars to appear on the page.
how can this be done?
and heard of isolation method.....but doubts whether it is available in EP 7
Thanks in advance.

I don't care about the iView functionalities...
this I am doing as part of the spacing issue I am facing with the iViews.
for URL iview I guess there is no isolation method.
for pages it comes.
but for some other iviews the isolation method is there.

Webdynpro application can't display a URL iView in a new External window

Fellow developer:
In my WD4A application, I called the method 'navigate_absolute' to display a URL iView in a new External window.
The code is as follows:
data lo_portal_manager type ref to if_wd_portal_integration.
call method lo_portal_manager->navigate_absolute
exporting
navigation_target = 'ROLES://u2026'
navigation_mode = '1'. ('0' - Displayed in the Same Window, " '1' - Displayed in a new External Window)
The application can display the iView in the same Window (navigation_mode = '0'), but cannot in a new External window (navigation_mode = '1').
In the iView properties, the following attributes are set to:
1. Launch in New Window - Dipslay in Separate Window
2. Open iView Links in New Window - Yes
If you know the answer, please advise.
Thanks

Need to send cookie to non-SAP backend from URL iView

Hi,
I have a backend application which takes a cookie for
(non-SAP) SSO purposes. I have created an URL iView
in my EP 6.0 SP2 that correctly displays the content
of that web page, i. e. the login screen.
However, even when I have a cookie in my browser, it still
displays that login screen, i. e. the cookie is either
not sent or not recognized.
I then created a simple test servlet on a backend server
that prints the contents of all the HTTP headers. When
I connect my browser directly to that page, I can see
the cookie. When I connect my iView to that URL, I
do not see the cookie. So apparently the iView does
not send the cookie.
As I learned, in EP 6.0 SP3 there is a "Fetch Mode"
property for URL iViews which allow to define whether
the URL in the URL iView should be retrieved by the
server or the client. This seems to indicate that in
SP2, always the server issues that request, which would
explain why there is no cookie in the request (since only
the browser holds these cookies). So I presume if I
would use SP3 with Fetch-Mode set to Client, this might
work. But then again, this fetch mode is not really
encouraged by the documentation and only recommended
if you are really desparate ...
So the question basically is:
- are my assumptions above correct?
- is there a way to have the EP server send cookies to
my backend systems with SP2?
I'm a little puzzled that this doesn't work out of the
box, since my understanding was that SAP SSO tokens are
also transported to backend systems using cookies, and
this is supposed to be on by default for EP. So I was
expecting to see at least the SAP SSO tokens in all
HTTP requests to backends. Apparently, the world is
not that easy.
Any insights would very much appreciated!
Thanks,
Matthias

Additional thoughts:
In general your assumptions are correct. When using client side fetch mode then the cookie should be forwarded, and I would not expect problems there. When using server side mode then the cookie domain changes and becomes the portal domain, and as a result the cookie is kept in the browser, but is a little useless. I'm not 100% familiar with how we solve this problem when using SSO2 cookie in server side. Yoav, can you elaborate ?
The reason the documentation was not in favor of client side is because at the time the idea was to encourage the users to use the portal server cache. However, this seems less relevant now, because only the first request will be cached, but not the inner calls of the html page.
Bottom line - I don't see any issue with using client side, and actually the default in FP is client side. So I would simply modify the iview to use it.

Hi Avadh,
Thanks for your reply.
I tested thru connection test of the system , it was tested successflly without any issues. all are into tick mark only.
but when i am trying to use the system alias name while creating Trasaction iview also i am not able to get the system alias name in the dropdown for selecting the system alias.
but system alias what ever it is "BIDCLNT100" is in active and connection test is done correctly without any issues.
Please let me know the problem why i am not able to get the same system alias name "BIDCLNT100" not able to get in the drop down list while creating the transaction IView??
Please reply , Thanks in advance
