Webdynpro or JSPdynpages

Hi Experts,
I have a client requirment with 20,000 concurrent users hitting the EP 6.0 server. Need to know which is the best approach for developing the portal application between webdynpro and jspdynpages.
What will be the performance issues in both the cases, if any ?
Thanks

hi bhavaniharikrishnarao
     both jspdynpages and webdynpros have there own advantages.
but,According to ur requirement,i recommend u go with webdynpros.
The main advantages of webdynpros are
         u can reload particular components for Eg Table page of data when click of Next button.so,this reduces the load on ur server and increases performance. but where as in jspdynpages the whole page get reloaded.
The other added advantages of webdynpros are
   1. Dynamic controls and reuseability
   2. Strict separation of layout data and business data through use of the Model View Controller concept
   3. Flicker-free screen construction.
   4. Web Dynpro supports a structured design process
               upto my knowledege,i fell tat webdynpros have better performance then jspdynpages.
Thanks
Ananth.

WebDynpro and JSPDynpage

Hi all,
Could any one please send me some documents on how to communicate between WebDynpro and JSPDynpage. Are there any examples in help.sap.com
Thanks.

Hi Neha,
You should use EPCF (Enterprise Portal Client Framework),
which allows communication between iViews on the same page in the client side.
In jspDynpage it is used in the form of javascript methods, as described here:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/771fa290-0201-0010-3d93-865e66cc6d7e
In Web-Dynpro you have java methods (which, I guess, are finally rendered also to javascript methods),
which are available from the class WDPortalEventing,
as described here:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/d35bb690-0201-0010-988a-d669c8530518
Note that the jspDynpage iView must be in URL Isolation for EPCF methods to work.
Hope that helps,
Yoav.

Can't pass event from WebDynPro to JspDynPage - why?

I Created JSP project and embedded in main page script (in its title),
which subscribes to event by EPCM API,
EPCM.subscribeEvent("urn:ru.intertech.common.wd.component", "save", go);
and created WebDynPro page that fires event using, when pressing on some bution:
WDPortalEventing.fire("urn:ru.intertech.common.wd.component", "save", navUrl);
but first code newer receives that event...
why so ?
for test reason I tested firing EPCM event on same JSP page,
and it was received,
also
I tested receiving Portal event "urn:com.sapportals:navigation", "Navigate"
it was received on same JSP page.
both iViews is not URL isolated according their properties.
WebDynPro package is:
package ru.intertech.common.wd.component;
note from else people expirence:
Does it important that receiving and firing side must be in same package? as written there:
https://www.sdn.sap.com/irj/scn/thread?messageID=462647
"The problem was that I created the Sender Application in package "com.sender" and the Receiver Application in "com.receiver".
I created them in the same package and it works."
What means domain for JSP page or WspDynPro component?
Does it important?
=================
JSP code is (changed script formattin to be able to post here, and removed else business content):
[hbj_content ]
[hbj_page_title"]
[script_type="text/javascript__"]
//alert["title started"];
//EPCM.subscribeEvent["urn:com.sapportals:navigation", "Navigate", eventHandlingFunctionName];
//EPCM.subscribeEvent["urn:ru.intertech.navigation:epcm", "Navigate", eventHandlingFunctionName];
//EPCM.subscribeEvent["urn:ru.intertech.navigation:epcm", "Navigate", pop];
//EPCMP.subscribeEvent[ "urn:ru.intertech.navigation:epcm", "Navigate", window,"eventHandlingFunctionName"];
 EPCM.subscribeEvent["urn:ru.intertech.common.wd.component", "save", go];
 EPCM.subscribeEvent["urn:com.sapportals:navigation", "Navigate", eventHandlingFunctionName];
 EPCMPROXY.subscribeEvent["urn:ru.intertech.common.wd.component", "save" , window, go];
function eventHandlingFunctionName[ eventObj ]
 alert["title started=" + eventObj.sourceId + ": " + eventObj.dataObject ];
function go[ evt ]
 alert["go started=" ];
</script>
 <hbj:form id="myFormId" >

your reply is worth.
what is the domains for views on one page?
where to see it?
Also, standard SAP MDM controls which we are using not working under any other browser except IE,
I tested on FF and Google Chrome, they do not erform dynamic part of the controls.
Despite this, debugging of scripts is important thing, so every piece is worth.
One more detail:
Also, two such a controls do not receive events from each other,
but ony within self..
why so ?

WebDynpro or JSPDynPage with HTMLB

We'd like to develop JavaApplications (PortalService, EJB,..) that will be called through a Portal-iView.
Some people from SAP say that it is better to use Java-iViews for frontend and others say that WebDynpro is strategic.
When looking at it, Java-iViews run inside the PortalPage where WebDynpro is always integrated by a generic WebDynpro-Java-iView using URL-isolation (IFRAME). This means that the browser always calls the WebDynpro-Content as if it comes from a dedicated server.
But WebDynpro has an easier and more standardized UI-design than HTMLB.
What are other pro/con's or recommendations?

Hi Prakash,
so for conclusion there would be the following possibilities for developing WebApplications being accessed through the Portal:
- use WebDynpro (with standard controls) for developing UI's that connect to components like EJB, PortalService, WebService, RFC-FunctionModule... containing the business-logic. This would clearly encapsulate the logic. Communication between iViews would take place through (client-side) PortalEventing.
- use Java-iView (PortalAPI/DynPage/HTMLB with specific control over HTML/JavaScript-Code) for developing UI's that can not be developed with WebDynpro because specific control of Clientside-Code is needed or the application runs completely in the Portal and has a simple UI.
- use ABAP-BSP for developing UI's when there is no WebDynpro for ABAP available on the same server and the application can not be implemented by RFC-FunctionModules.
Taking this scenario, looking at where the UI'Component would run:
- the Java-iView must run on the PortalServer
- the WebDynpro must run on the PortalServer when using PortalService
- the WebDynpro could run on the PortalServer or a dedicated server when using WebService or RFC-FunctionModule
- the WebDynpro must run on the same (dedicated) server when using EJB, ABAP
-> is this correct (e.g. EJB must be on same server as WebDynpro) and does it make sense?

Topics on EP and the sequence to be followed

Hi ,
I have explored a few topics on the development side of the portal and there are a few on my mind .What I wish to know is if I have to develop a team of delivery capability then in what sequence these topics are to be taken with the team . I am listing the topics below . Please guide as I have never been on a project on EP so I am not aware about the importance of these topics and the sequence to be followed while taking them up with a team .
Iviews : These include
Making iviews using standard templates available .
Making iviews using visual composer .
Making customised iviews using PDK(NDS and WAS) .
Webdynpro application
JSPDynpage
Business Packages
Integration of Third party applications
Configuring your mail server with the portal .Learning the configurational concepts of the exchange server .
BSP applications
HTMLB and tableviews
BISDK and XMLA
Using JCO and JCA
Knowledge/content management
Collaboration
TREX
If you have some other topics in mind please feel free to include here and also specify where do you wish to include them in the sequence . I need to know how do we go about this as it becomes quite confusing as to what to persue and with what importance as I have never faced a real time client requirements.
I AM LOOKING FOR AN EXPERT ADVICE HERE .
Regards
Deepak Singh

Hi deepak
I think you can go for this sequence
Making iviews(Making iviews using standard templates available .) and other pcd objects like worksets,pages etc..
Creating users,roles and Assinging roles to users
Making iviews using visual composer.
Knowledge/content management
Customization of portal.

Passing parameter from JSPDynpage to Webdynpro

Hi,
I am trying to get parameter in webdynpro application from JSPdynpage and i have pasted my code snippet.
JSPDynpage Code:
EPCM.doNavigate('My Targett URL');
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
request.getServletRequest().getSession().setAttribute("PNUMBER", "10001");
In webdynpro:
HttpServletRequest request = ((IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest();
HttpSession session = request.getSession();
pNumber = (String)session.getAttribute("PNUMBER");
From JSPDynpage it navigating to webdynpro application but getparameter() always null.
I cross checked both JSPdynpage and webdynpro session getId() both are returning same id but parameter is not passing.
where i am doing wrong?
thanks in advance,
regards,
SKB

Hi SKB,
The problem is that portal applications and Web Dynpro applications have different sessions (even if they have the same session ID). All portal applications are technically one J2EE application (called "sap.com/irj") and all Web Dynpro applications are technically one J2EE application (called "sap.com/tcwddispwda"). The reason why sessions must be different, is because of the J2EE specs. Below is an extract from the Java Servlet Specification 2.4.
SRV.7.3 Session Scope
HttpSession objects must be scoped at the application (or servlet context) level.
The underlying mechanism, such as the cookie used to establish the session, can be the same for different contexts, but the object referenced, including the attributes in that object, must never be shared between contexts by the container.
To illustrate this requirement with an example: if a servlet uses the RequestDispatcher to call a servlet in another Web application, any sessions created for and visible to the servlet being called must be different from those visible to the calling servlet.
The solution to your problem is not to use session attributes, but URL parameters. In your JSPDynpage use something like this
EPCM.doNavigate('ROLES://portal_content/foo&DynamicParameter=PNUMBER%3D10001');
And in your Web Dynpro application use something like this
String pNumber = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("PNUMBER");
Kind regards,
Sigiswald

Best practice for connecting to SAP backend from JSPDynPage

Hi,
Can anyone help clear up some confusion I have over connecting to SAP from Java?
We have a number of JSPDynPage portal applications on EP7 Ehp1 that connect to SAP ECC6.
We currently use 2 methods to call remote functions on the ECC system.
1) Enterprise connector and JCo Client Service
This method has the advantage of automatically generated proxy classes and typed access to function module parameters. It is also more closely aligned to Web Dynpro from a design time point of view
However it also has a number of disadvantages in that it does not support table APPEND structures and requires regeneration for every change to the ABAP structures involved even if the field that has changed is not being referred to. In addition the use of the JCo client service means that the connection pooling must be handled ourselves explicitly
2) Connector Framework - SAP System Connector
This method has the advantage that connection management is handled by the framework. It also has the advantage that fields are referred to by name so if an ABAP structure changes then the remote call will not fall over as long as the named fields are still available.
However this method is more cumbersome because no proxy classes are generated and function module parameters are referred to generically so errors are not picked up by the complier.
Given the limitations of the above 2 methods, what is the recommended approach?
In the book u2018Inside Web Dynpro for Javau2019 Chris Whealy says the following about the Adaptive RFC Layer:
u2018Any Java program running in the AS Java u2013 not just Web Dynpro u2013 can make use of the Adaptive RFC layeru2019
Has anyone been able to use the Adaptive RFC layer from a NON-WebDynpro java application?
Any thoughts on the above would be most welcome.
Thanks,
Denis.

Hello,
The recommended way is with JCA Connector.
Adaptive RFC is included from NW7.1,
See "Creating an Adaptive RFC2 Sample Application without using Web Dynpro"
in the SAP HELP of NWCE7.1 or NWCE7.2.
Seems to be based in JCo 3.0 and Java5 so it will not work in NW70.
For older Versions like EP 5 there is also a JCo ClientService available.

Johannes

HTMLB, WebDynpro or both together?

Hi @ all,
I had a look at some possibilities to create Portal Content .
I read something about HTMLB and the comparison to WebDynpro in the SDN Forum.
Some guys are saying that they would prefer HTMLB and some others saying that they prefer WebDynpro.
My question now is, what is the difference for the EP if I have a HTMLB IView or a WebDynpro IView. I know that Webdynpro uses a SLD to get the backend connection and so on.
The Business Logic is fully implemented in R/3 so the IViews are only for displaying content.
Because we have not much time and UI Design in HTMLB take much time, would it be an solution to source out some very complex Graphical UI Views to Webdynpro. I think this would save us a lot of time, or?
Is it possible to access in Portal from an HTMLB to a WebDynpro and reverse? Could I trust in it, that these both different kinds of development will work together?
It would be really nice if someone could give me some good hints and anwsers to this topic.
Thanks and Kind Regards
Dennis

Hi Dennis,
> Some guys are saying that they would prefer
I really depends. First, it depends on experience, even if this is not a really objective comparator... And it depends on what you want to do. If for example you'd need some heavy KM integration, there are many reasons for using HTMLB.
> Business Logic is fully implemented in R/3 so the
> IViews are only for displaying content
That's a "classical" scenario for using Web Dynpro, for you have some automatism to create the backend connection as well as the mapping of the table values into your UI.
> I think this would save us a lot of time, or?
If you have some experience in WD, then yes. If you have no Web Dynpro experience but much experience in HTMLB, then you'd probably be faster in HTMLB and JSPDynPage, but that shouldn't be a reaon to stick to this technique, for once you have gained the necessary experience, at least next time you will be faster
> Is it possible to access in Portal
> from an HTMLB to a WebDynpro and reverse?
In general: Yes. But that can get quite tricky. If you only want to "enter" the WD app from the JSPDynPage app and vice versa - no problem. If you want to leave the WD app at a certain point but return later - also this is possible in the meantime.
> that these both different kinds of development
> will work together
In general they do, but a complete application should be developed in the one or the other technology. Otherwise, you would have mixed UI (even if using the same style, WD and HTMLB pages just look different), double coding for R/3 connection, etc.
Hope it helps

hi Jagadeesh,
are you using SLD related configurations anywhere for your application? From the error message it seems the CIM client generation falied due to some reason. You can check from the Visual Admin of both your DEV & QA systems to find any mismatch.
Go to Visual Admin -> Server -> Services -> SLD Data Supplier -> CIM Client Generation Settings and see if you can find any difference. Normally here in the HTTP Settings tab and CIM Client Generation tab you should mention your SLD URL and logon details. You can check the CIM client generation setting by clicking the "CIMCLient Test" button under the CIM Client Generation Setting tab.

Call a Portal Application from WebDynpro

Hi experts,
i hope you can resolve my problem!
My intention is to refresh the browser and call the first page of the portal after the portaluser pressed a button in an WebDynpro application.
For this purpose i create a portal application with an JSPDynPage and an JSP how call the JavaScript Method "top.location.reload();".
My question:
How can i call an portal application in a WebDynpro onAction Event?
Thanks,
Florian

1)Creat one action method "ReactPortalEventing" with the parameter dataObject and write the code in wdDoInit method as
//the urn and method name like "sendEvent" both should be same
WDPortalEventing.subscribe("urn:com.abc.practice","sendEvent",wdThis.wdGetReactPortalEventingAction() );
2)and in the action method display the name as
wdComponentAPI.getMessageManager().reportSuccess("Event value"dataObject);
also chk it
