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?

Test iView (htmlb & JSPDynPage) with Eclipse

Hi,
I am new and I wonder if it is possible to test "iView" generated in JSPDynPage and HTMLB with Eclipse without having a SAP Portal installed.
I developp JSPDynPage and HTMLB in local (no SAP Portal, no network) and I would like to see result of developpment before to deploy and test it in the Portal
And if it is possible, how do to it ? (plugin ...)
Thanks a lot,
Fabien

H Fabien,
simple answer: No, at least not for EP6, independent if SP2 or higher (NW04). "One upon a time", for EP5, there has been the PDK as a runtime development environment, but this has gone (which, I think, was the right decision, for having differences between this dev runtime env and the "real" portal).
The conclusion for many people is to have locally installed dev portal installations in before a central dev portal instance.
Hope it helps nevertheless

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.

Integrating WebDynpro ABAP applications with UWL for workflow in Portal

Dear
We want to integrate an abap webdynpro application as task in the workflow with UWL.
More information was found in /people/ginger.gatling/blog/2005/12/14/create-new-uis-for-existing-workflow-tasks-with-abap-web-dynpro-and-universal-worklist
But no answer on the following issue:
We use the transaction SWFVISU to prepare standard setting for our task. This defines how a task is executed, once you select the task subject line on the worklist.
Task                           TS91700001

But we want to start the abap webdynpro application with a dynamic parameter: period 07.2010 or 08.2010 or MM.YYYY. This parameter is a container element of the task, filled when the task is created. Also other parameters are available in the abap webdynpro application.

Can we set the dynamic parameter list DYNPARAM from the task
or should we read the container in our abap webdynpro application described in http://wiki.sdn.sap.com/wiki/display/WDABAP/IntegratingWebDynproABAPapplicationswithUWLforworkflowin+Portal?

Java webdynpro is compatible with VC?

Hi Experts
Whether Java webdynpro is compatible with VC?
What I mean is whether Webdynpro projects can be imported into VC and further modified.Please respond me as soon as possible
regards,
Noel

Hi,
no this is not possible.
VC is pure modelling; you can run a web dynpro from VC (and even within) by making use of HTML forms, but that's it !
In the next release (7.1) it will be possible to integrate web dynpro components, but it is not clear yet how this will be done.

BSP's with htmlb - Tags on Browsers for Apple Computers

Hello,
I have a question. I use htmlb - Tags in a lot of BSP's. At the most Browsers for Windows Systems there is no problem, but at the Safari Browser or the Internet Explorer for Apple Mac OS X the Sites with htmlb - Tags won't work.
Does anybody know why?
Greetings
Timo

hallo Timo,
Actually on Friday we got an official update on the question of Safari support. In summary SAP will <b>not</b> natively support the Safari browser. However, what we will do, for <u>design2003 only</u>, is to recognize the Safari browser as an IE6 browser. The official statement is that what works, works. No code changes will be made to handle any special cases of Safari browser. It is acceptabled that Office Integration, handling of PDF documents and any ActiveX stuff will not work.
This change should be in 620SP46 or SP47. If you should be in a hurry, consider to modify our browser recognition code already now.
bye, brian

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 <b>on the same page</b> 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 <b>WDPortalEventing</b>,
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.

Problem with htmlb:chart after upgrade

We just upgraded from BW 3.0, WAS 6.20 to BW 3.5, WAS 6.40. Testing revealed that my htmlb:chart would no longer work. I just got a white screen whether using Internet Explorer or Netscape. After much digging, I found that the values for charttype changed with this upgrade. Any value before that was COLS* now is COLUMNS*
This is just a "for your information" in case you run into this.

WebDynpro proxy page with Webdynpro iView and SAP Gui for html iView

Hello,
I have a requirement to have a page that has at the top of it a webdynpro for java iView screen with several links that when pressed pop-up various data pulled from the back-end. This part is fine and presents no problem. Beneath this the requirement calls for a SAP Gui for HTML iView to be displayed. Which is no problem either. The problem occurs when one of the links in the java webdynpro application at the top of the screen is pressed it causes the SAP Gui for HTML portion to refresh and come back to the beginning. So for example you first navigate to this screen and you go into the sap gui for html portion and drill into 2 or 3 screens in the sap gui for html transaction. If you then press one of the webdynpro links the sap gui for html (which is a separate iView) refreshes and you are taken back to the initial screen. This only occurs when using a web dynpro proxy page. If I use a standard page the SAP Gi for html does not refresh. Unfortunately there are other things not mentioned here that require us to use the webdynpro proxy page.
Any help is greatly appreciated,
Bert

Use System admin -> System Config and find your system in the PCD (under portal content). Right click and open -> permissions. Find a user or group or role and give it the end user permission. I'd suggest the group Everyone.
Cheers
