Redirecting from an abstract portal component

Hi,
I'm trying to redirect from an abstract portal component to a quicklink. I do it like told in this thread:
Redirecting to external website from abstract portal component?
private void redirectUrl(String target, IPortalComponentRequest request) {
try {
    HttpServletResponse resp = request.getServletResponse(true);
    resp.sendRedirect("../../../../portal/" + target);
} catch (IOException e) {}
It works, but the content of my target-URL is still in the Portal-Frame. So I've two time the Portal-Framework-Navigation. Something like this:
| Welcome         |
| Welcome         |
| content         |
|                 |
|                 |
|                 |
My goal is to redirect the whole page, not only the frame.
Thanks for any help...
Regards, Markus

Perhaps I can do it with
public void doOnNodeReady(IPortalComponentRequest request){
request.redirect("http://www.google.de");
But like in this Tread, it didn't work AbstractPortalComponent and doOnNodeReady

How to use UI elements in abstract portal component

hi all
i am new to portal development..i want to use different UI elements such as textbox,buttons using abstract portal component.can anyone telme how to use them.

You can use JSP , JSPDyn pages in Abstract portal component.
You can call a Jsp file from the abstract portal component.
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
     com.sapportals.portal.prt.resource.IResource somePage =
               request.getResource("jsp", "pagelet/test.jsp");
               response.include(request, somePage);
Then you can made your desired UI in JSP.
Hope this helps..

Use WebDynpro JCO Destination in Abstract Portal Component

Hello,
I was wondering if it is possible to use a WebDynpro JCo Destination in an Abstract Portal Component? I have a portal component that make as JCO call to run an rfc. I get the MYSAPSSO2 ticket from the cookie and pass this in to the JCO client. This works fine. Now I need to be able to run this for anonymous users as well. I was hoping to be able to retrieve a WebDynpro JCo destination that is set up as a userid/password type and use this to make the connection to run my RFC. This way I could avoid having to store the userid and password somewhere and encrypt/decrypt it etc...
Thanks,
Bert

Redirecting to external website from abstract portal component?

Hi,
I have developed an abstract portal component and trying to be redirected to an external website ex : www.google.com
here is the code...
public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
HttpServletRequest req = request.getServletRequest();
String queryString = req.getQueryString();
String redirectURL = queryString.substring(queryString.indexOf("=")+1);
HttpServletResponse resp = request.getServletResponse(true);
resp.sendRedirect(redirectURL);
OR
RequestDispatcher rd = req.getRequestDispatcher("www.google.com");
rd.forward(req, resp);
But couldn't able to redirect in either ways ..
exception was ... iView not found: www.google.com.
Any help?
Thanks
MMK

Hi Mohan,
When you do a redirect you need to provide a URL. From javadocs
Sends a temporary redirect response to the client using the specified redirect location URL. This method can accept relative URLs; the servlet container will convert the relative URL to an absolute URL before sending the response to the client.
Thus when you provide just "www.google.com" the converted complete URL will be something like http://portalserver/irj....www.google.com whcih of course does not exist as a portal component. Thus you get the error iview not found.
Hence you need to give a full URL and not a relative URL.

Call jspdynpage or Abstract Portal Component from SAPUI5

Hi,
I am new to SAPUI5, so might ask basic and dumb questions.
I am trying to develop an application in sapui5 which should have the functionality to read and write a file to the server. It is different from file upload as the user wont be selecting any file, rather the data in the form should be written to a file in the server on a click of a button. After doing some research I figured out that sapui5 doesn't give an option to read/write a file to the server.
So, as an alternative I thought of developing a service, an SAP portal application (jspdynpage, WDJ, abstract portal component - or if you can suggest any other app) that can be called from the sapui5 for reading/writing purpose. The data can be received/sent as an xml, and in the sapui5 application I can parse the data and do the needful.
Now my question is how to call the portal application (that would be a url) without redirecting, and pass the necessary parameter? Sapui5 should just call that url and data should be passed or received as a parameter. I am not sure if OData model call will work, as I am getting an exception. Can you please provide a solution to this?
Ps: We are on SAP EP 7.3 and would like to stick to SAP apps, and no additional database etc.
Regards,
Piyush.

Hi All,
I found a way to do that. I created an Abstract Portal Component application that accepts data through url parameters. Used the regular java APIs to read/write files to the server.
Now the challenge, at least to me, was to call this application from SAPUI5 application. I used ajax call.
var response = $.ajax ({
url: "<url>",
type: "POST"
Next, will also try to find if I could use any of the models provided by SAPUI5 to call the portal application.
Note: Make sure both your sapui5 app and the portal application is deployed on the same server, else it wont be able to authenticate (SSO wont work) and you may receive exceptions.
Regards,
Piyush.

          response.write(" Response from Service " + uid.getData());
         }catch (Exception e)
              response.write(e.toString());

Calling a abstract portal component from portal service

Hi
Can i access a abstract portal component from portal service?
My requirement is i have a method called getsessionID in portal service. My portal service is enabled as a webservice. Who ever consumes my webservice they will call this method.
This method in portal service should call a method in abstract portal component to return the session id of the user.
is this possible.
Thanks in advance
Kishore

Hi Kishore,
This is impossible. The AbstractPortalComponent is a servlet and it can only be executed via URL. It is easy to execute the component via url but you have to pass the logon information. Also it will run under a user context that you have specified(while passing the logon information) when calling the url. I think you ought to consider a different approach.

Event Handling in Abstract Portal Component

Hi Friends,
I am using HTMLB Classlib in an Abstract Portal Component to develop a Dropdownlistbox. Now I want to handle the event of change of selection in this dropdown. However, this event is not getting captured. Sample code is as follows:
public class dropdownsimple extends AbstractPortalComponent
                       public void onClick(Event event)
                       public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
                                                IPageContext myContext1 = PageContextFactory.createPageContext(request, response);
          Form myForm = myContext1.createFormDocument("CRMForm");
          GridLayout myGrid = new GridLayout();
          DropdownListBox drp = new DropdownListBox("drp");
          drp.addItem("Key 1","Item 1");
          drp.addItem("Key 2","Item 2");
          drp.setOnSelect("onClick");
                                                 myGrid.addComponent(1, 1, drp);
          myForm.addComponent(myGrid);
          myContext1.render();
I am able to see the dropdown box along with values when I preview the PAR iView created from this component. Please let me know how to capture the event of change of selection in the dropdown?
Edited by: Shetul Chothani on Jun 21, 2011 6:37 AM

Hi,
Change this line
drp.setOnSelect("onClick");
to
drp.setOnSelect("click");
and leave the line
public void onClick(Event event)
as it is, and it should work just fine.
I.e., if you name your event "fooBar", the event handler should be named "onFooBar"
Cheers,

Difference between Abstract portal Component and JSPDyn page.

Hi Experts,
What is the difference between Abstract portal Component and JSPDyn page.
Thanks,
Jay.

Hi,
The PDK provides two methods for creating a portal component:
Abstract Portal Component
The Abstract Portal Component class offers a lean method for writing HTML commands to the Web client as well as for basic event handling. It is an implementation of the IPortalComponent, which is the central abstraction of the Portal Component API.
DynPage
The Page Processor Component, which extends the Abstract Portal Component, returns a DynPage. It provides more sophisticated event handling. Controls that produce events (such as buttons and checkboxes) have an event attribute that contains the name of the event handling method. This event handling method is invoked by the DynPage when it occurs.
The JSPDynPage is an implementation of the DynPage and allows the use of the DynPage in combination with JSP (Java Server Pages).
The PDK documentation and examples focus on the DynPage. Easier event handling and the separatation of content development (JSP) from application development (Java) make the DynPage a better choice for components with interaction and changing content.
For more details, Refer thes thread,
https://fortress.wa.gov/dop/portal/irj/portalapps/com.sap.portal.pdk.basic.portalcomponentimplementation/docs/jspdynpage.html

Access KeyStoreManager within an Abstract Portal Component

Hi together,
we have a X.509 compliant certificate located in the keystore on the j2ee engine.
The private key is used to create the digital signature on the ticket content.
We need to transfer user credentials to an external portal. This portal only supports SHA1 with RSA. The key-pair was created with the RSA algorithm.
The problem is following:
I need to use an Abstract Portal Component. It is no problem to get all the needed user credentials.
But i don´t have a clue how to get to the certificate for singing the ticket content with RSA/SHA1.
I have already read the help on http://help.sap.com/saphelp_nw04/helpdata/en/a4/d0201854fb6a4cb9545892b49d4851/frameset.htm , but it did not work.
Has anyone of you specialists a solution for this problem?
If you need more details, don´t hesitate to ask
Thanks in advance

Perhaps I can do it with
public void doOnNodeReady(IPortalComponentRequest request){
request.redirect("http://www.google.de");
But like in this Tread, it didn't work AbstractPortalComponent and doOnNodeReady
