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.

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,

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

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,

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

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,

Yes Asusha
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);

When you say submit do you mean HTMLB submit or a normal HTML form submit? If it's the latter, you just need an action on your form...
<form action="jspfile2.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

Hi Nari,
Follow the below steps:
1. Store your properties files (test.properties, test_en.properties, test_xx.properties where xx is the locale ) in the folder PORTAL-INF ->Private ->classes
2. In portalapp.xml for component-config, add this
<property name="ResourceBundleName" value="test"/>
3. In your abstract portal component you can use the below code to fetch the value for the key "SERVER_NAME".
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
         ResourceBundle resourceBundle = request.getResourceBundle();
         if(resourceBundle!=null)
              response.write(resourceBundle.getString("SERVER_NAME"));
         else
              response.write("Error");
Let me know if you still face any issue.

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.!!

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.
