Page Imports in Abstract Portal Component

Hi,
I have created an abstract portal component where I have called a JSP using IResource.
The JSP is called and displayed.
<%@ page import = "java.util.*;" %>
<%@ page import = "com.sapportals.portal.prt.component.*;" %>
<html>
<body>
hello
</body>
</html>
In my JSP the moment I add the second import i.e. prt.runtime, it throws an error when I run the application:
Error when rendering jsp.
Am I missing out something?

Hi Prem,
Add that particular jar file in the lib folder of your application and also add it to the build path of your project properties.
<b>Project -> Properties -> Java Build Path -> Libraries</b>
Add to this build path as well.
I hope this helps you.!!

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,

Abstract Portal component - KM Html

Hi,
We are developing an external facing portal wherein the Home page has 6 components. In that 5 components are static components which refer to the HTML file in the KM repository. For that I have made KM document iview and given the path of the HTML file.
But as it is an internet page and as its loading time should be less, we planned to make each component as an abstract portal component which refers the HTML file in the KM and displays the same.
Can somebody tell me as to go about it?
Thanks & Regards,

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");

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

But, the request object is not available.
How to I get the same object available here?

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

Refreshing a Abstract Portal Component in Specific Intervals

Hi All,
I have developed an Abstract Portal Component which reads Data from an XML File which is stored in KM.
Requirement :
I need to REFRESH this iView for every 5 Minutes-Automatically (Just like Websites showing Live Cricket Scores), to read the Updated Data from that XML File. The XML File will be updated every 5 mins.
If anybody has Idea on this, Please Guide me..
Thanks in Advance.

Here are the instructions for Client-Pull method using meta tag
1. Use META in the HEAD section of your document.
2. Write HTTP-EQUIV and CONTENT in META to accomplish client-pull.
Examples
To reload the document itself:
HEAD
META HTTP-EQUIV=REFRESH CONTENT=5
HEAD
CONTENT=5 means wait for 5 seconds to reload the page.
To load visitors to another page:
CONTENT=5 means wait for 5 seconds to reload the page.
To load visitors to another page:
HEAD
META HTTP-EQUIV=REFRESH CONTENT="5;URL=http://mbiz.co.th/tips_tricks/"
HEAD
URL=...... This is the URL of the page you want to load a visitor to.
using java script window location you can refresh the page
like window location equals your location
and call the method which contains window location in body onload

Abstract Portal Component VS Dynpage

Can any one explain the differences between Abstract portal component and JSP DYN PAGE?
When to use where ?
How can we provide communication between iViews with in the same component / different components.
Useful answers will be rewarded with points.
Thanks

Mohan,
Abstract portal component as it says its an abstract component .In portal applications we have certain requirements which include only some business logic to be implemented ,for such cases u write the function in abstractportalcomponent and use this as a single entity.It generally not used for building applications with UIs..
So for a portalapplication wher u need to include UI,controller,and databased/Backend connectivity .JspDynpage suits here.It is the framewrk provided which has JSP view,java controller,and beans model..
For instance if u have developed a user login form and saving it to database.
U develop it using JSPdynpage.
But her if u have an enhancement of including the page to be printed.
U can create a abstractportalcomponent and use it in earlier Jspdynpage.
So advatage is modular specific business process can done and integrated with an application..
Future advancements is easy.

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,
Robin

How to Link another JSP Page in the same portal component

Hi Guys,
I am a new guy to SAP, currently, I want to add href link to another JSP in the same component, so I used <a href="<%=webpath%>/jsp/AboutPage.jsp">, but obviously, the link can not display target page due to privilege restriction, does anyone know how to resolve this problem? thanks very much!
Best Regards
James

Thanks srinivas,
   Sorry for late response, too busy yesterday.
   Currently, I want to create a URL link in the page which links another JSP page in the same portal component, but the problem is this JSP page is under PORTAL-INF folder, so due to privilege problem, I can not create the link like the following:
<a href="jsp/test.jsp">Link</a>
   I konw if I move test.jsp out of folder PORTAL-INF, the above way should work, but then, I found the JSP page can not access componentRequest and get resource bundle object.
Am I clear, please let me know, thanks!

Reading Session Variables in Abstract Portal Component/ JSP Dynpage or Java

Hi All,
I have a web dynpro for Java component which passes parameters in a session and also navigates to a Java application.
Now when I try to read the session parameters in the Java application (JSPDynpage or Abstract Portal Component) I cannot retrieve the values.
Can someone throw light on how I can achieve this within a Java application.
Code is as enclosed below -
WD for Java Code
public void onActionClicked(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionClicked(ServerEvent)
IClientSession session = Utils.getCurrentClientSession();
IScope scope = session.getScope();
scope.put("TestSession", wdContext.currentContextElement().getTxtValue());
WDPortalNavigation.navigateAbsolute(
"ROLES:portal_content/com.be.pct.cr.Test/DynProToNet",
WDPortalNavigationMode.SHOW_INPLACE,
(String)null,
(String)null,
WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
(String)null,
(String)null,
(String)null);
    //@@end
Code within the Abstract Portal Component doContent method is -
IPortalComponentSession ses;
ses = request.getComponentSession();
String TestSession = new String();
String sTest = new String();
String sTesting = new String();
if(ses.getValue("TestSession")!= null){
TestSession = ses.getValue("TestSession").toString();
if(request.getParameter("TestSession")!= null){
sTest = request.getParameter("TestSession");
if( request.getValue("TestSession")!= null)
sTesting = request.getValue("TestSession").toString();
response.write("Display"TestSessionsTest+sTesting);
Any help is highly appreciated.
Thanks in advance,
Divya

Hi,
Why not use eventing between webdynpro and portal applications? That would be more easy. Check these documents.
