Hi Khushboo,
The "formal" way to extract data from R/3 is by calling BAPI functions. this is not wise to access R/3 tables directly, since consistent data saved on more then one table.
Therefore you should only use JCo or JCA to retrieve Data from a backend system via BAPIs or your own RFC enabled Function Modules.

XML toolkit or XERCES + XALAN in portal component Please HELP

Hello,
is there anybody that has succesfully used xalan and xerces in a portal component?
I have an application that requires them but have found no way to have them working in the restricted classloader area of portal component developed in java.
Best case my portal component still uses xml toolkit, worst case, when I try to add them as j2ee or irj libraries, portal does not even boot.
Help needed !
Thanks in advance
Vitaliano Trecca

Victor, Xavier is right.
I have already tried that but does not work. Classloader still finds SAP XML Toolkit factory. I also tried forcing System properties but things go even worst: it affects portal behaviour.
The only working way seems to be to load the parser implementation directly instead from the default factory but this is far from being a clean way.
Any suggestion to ensure my PDK will see Default factories from xerces and xalan and keep off from XMLToolkit?
Regards!
Vitaliano

Development Tool for Portal Component

Hi all,
I am preparing the environment required to develop SAP NetWeaver Portal Component. I've downloaded SAP NetWeaver Developer Studio 7.2, however, I can't create a Portal Application as has been instructed in the SAP documentation. There's is no option as "Portal Application" in the new project creation wizard.
Any help is appreciated.
Thanks.

Hi,
there are many tools for monitoring different stuff on portal in different ways, but as you said you are new i would suggest you to go with manual stuff so that more things can be viewed.
please check below links for more details:

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"

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,

Creating iViews Based on Remote Portal Component iViews

Hi,
Does anybody know if Portal 7.0 EHP 2 supports creating a local iview for a remote transactional iview? I saw this SAP Help link, but it is not really clear on Transactional iviews.
http://help.sap.com/saphelp_nw70ehp2/helpdata/en/f7/34fe8694c84512a2c62cc6d145736e/frameset.htm
Thanks
Sathish

Hi Prasanna,
this needs some clarifying concerning wordings:
1.) An iView is an "instance" of a portal component. Within the Portal, you have deployed different applications, each app consists of one ore more components (and/or services, but services are faceless).
2.) The "traditional" way to implement such a component is to do it directly via HTMLB, JSPDynPages etc. Deploy this app within the portal and then you can create an iView build directly on this component.
3.) Alternatively, you have components at hand, which import other applications / or web stuff. The most simple for example is an URL-iView. This is an iView using a component which just retrieves the content from some URL given. A more complex example is the ApplicationIntegrator, which does the same plus passing login params etc.
4.) One possibility is to integrate WebDynpro-Applications via a specific WebDynpro iView. The combination of this has the added value that from WebDynpro Applications you are able to use the Portal Services, so you have a far more tight integration.
5.) With all this at hand, the rest should be self declaring: Yes, you can develop "normal" J2EE-Apps, based on "good old JSP/Servlet + EJB" technology and integrate it via URL/AppIntegrator iViews. But you can also use WebDynpro for your frontend and EJB's for your backend with the advantage of tighter integration.
Hope it helps

Using JDO in a portal component.

Hi!
I've tried using JDO in a portal component (DynPage), but it just won't work for me (WAS 6.40).
What I've tried is this:
- Looking up a PersistenceManagerFactory using the name "java:comp/env/jdo/defaultPMF"
This does not work ... I get a NameNotFoundException: Path to object does not exist at java:comp, the whole lookup name is java:comp/env/jdo/defaultPMF
- After reading this forum I tried with the name "deployedAdapters/jdo/defaultPMF/shareable/jdo/defaultPMF" although this is probably not the correct way
This did return a PersistenceManagerFactory object, however I wasn't able to cast to the PersistenceManagerFactory interface that I had. It must have been different versions of the interface - I tried downloading the jdo.jar from Sun and compiling the portal component against that, but still the ClassCastException occured. I used the reflection API to determine that the object returned did in fact implement the interface named javax.jdo.PersistenceManagerFactory. I even tried using the jdo.jar libraries from the server, but to no luck.
So ... my question is: Is JDO not available from a portal component? Must I develop a J2EE application to make it work? If so, I'd rather use Hibernate in my portal components, but it seems stupid when JDO is available?
Thanks,
Thomas

Hi Thomas,
In order to be able to use JDO in a Portal component, you have to add a Private Sharing Reference to the application sap.com/com.sap.jdo. This is a standard application provided with the SAP WebAS Java installation.
For more info on how to do that, please refer to <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/ep/g-i/how%20to%20access%20an%20ejb%20from%20a%20portal%20component.mht">this</a> tutorial -> Accessing the EJB -> New Portal Component -> scroll to the section "Add PrivateSharingReference".

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?

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.

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);
Then you can made your desired UI in JSP.
Hope this helps..

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.

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
