I found the following document:

But I what know When I should use the Web Dynpro Proxy Page option and When I should use Default Page Template
Can Anyone help me with suggestions, please.

Hi.
Default Page Template: Creates a page based on the regular portal page template
Web Dynpro Proxy Page: Creates a page based on Web Dynpro technology
But I created the page with the two options, but I not find differences between the two options with respect to Layouts, and others.
Can anyone help me with suggestions.
Thank You in advance.

Custom Layout for Web Dynpro Proxy page

Hey all
I have a requirement to display 4-5 Web Dynpro for ABAP iViews on a page.
I have the option of using the standard PRT page to display these iViews for which I can create a custom layout using com.sap.portal.layouts.default.par and the simple JSP layout file in it.
However, they should really be on a Web Dynpro Proxy page but custom layouts created using above component wont work.
In the document [Integrating Web Dynpro and SAP NetWeaver Portal|https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/0c7b2f25-0c01-0010-f2a2-f8a65a9dcad9] it says -
Within the SAP NetWeaver 04s release it is not possible to define application specific page layouts for Web Dynpro pages. Within the SAP NetWeaver 07 release this will be possible. Layouts for Web Dynpro page are implemented then as Web Dynpro components implementing a special ILayout Web Dynpro component interface.
Has this been released as yet?
Anyone find the APIs or workaround for this?
Cheers

I have the same question, but can't find any good solutions for this.
For standard portal applications you can use com.sap.portal.design.layouts and modify layouts via JSP. But all webdynpro proxy pages are using their own layout.
I'd like to change that layout too.
Anyone?

Web dynpro proxi page

Hi,

I am having a similar problem.
I cannot see the Default Page Template, and wondering what I need to do to make it available.

EREC: theme for Web Dynpro ABAP pages (external candidate)

Hello,
I have created a custom theme in the SAP Netweaver Portal for my customer and now I have the requirement to use the same theme for my stand-alone Web Dynpro ABAP applications (pages for the external candidate). Is it possible to use the same stylesheet as in the portal, without having to recreate a theme?
I tried several options, but none of them did work:
A. Downloading the portal theme as a ZIP file and then uploading it in ERP using the report BSP_UPDATE_MIMEREPOS (after unzipping) to a location /SAP/PUBLIC/BC/UR/nw5/themes/CUSTOM_THEME. After that, I call my application with the additional URL parameter sap-wd-themeroot=/SAP/PUBLIC/BC/UR/nw5/themes/CUSTOM_THEME but it does not work (the app is displayed with the default sap_tradeshow stylesheet)
B. I also tried calling my app using the URL parameter sap-cssurl=/SAP/PUBLIC/BC/UR/nw5/themes/CUSTOM_THEME but here again, it does not work (the app is displayed with the default sap_tradeshow stylesheet)
C. Downloading the portal theme as a ZIP file and then uploading it (zipped) using the report WD_THEMES, but here I receive the error "no themes found in the ZIP file". I have the same error if I upload only the ur.zip I receive from the portal (instead of uploading the whole *.zip file)
I checked the UR versions both in portal & ERP, and we had a lower version in the portal than in the ERP, so we upgraded the portal version according to SAP note 1446099. Now we have a higher version in the portal than in the ERP. We regenrated the portal theme and downloaded it again, but with the same result.
Does anyone have an idea what could be the solution to our problem?
Thanks in advance!

I would recommend to try another way. If it is possible to access any SAP Portal from outside you can use two URL Parameters to integrate the Portal style sheets in a standalone WDA application. The parameter sap-cssurl contains the absolute URL address to the style sheet and parameter sap-cssversion the current SAP Portal style sheet version. For all external facing scenarios it is important to use the whitelist mechanism to block unknown URLs.
Example
?sap-cssurl=http://myportal.myserver.com:50000/irj/portalapps/com.sap.portal.design.urdesigndata/themes/portal/mytheme/ur/ur_ie6.css
&sap-cssversion=7.11.5.20.0
I canu2019t recommend to raise manually the version number. You will not get an consistent system this way. The meta data (project.zip) are outdated and of course you will get an outdated theme.

I am getting a error while executing the Web Dynpro Application Page.

Hi All,
I am getting a Error while executing a web dynpro application :::
: Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered. Component: Z_WEP_PERSONAL_DATA, View: OVERVIEW, Window: Z_XXP_PERSONAL_DATA
I have checked this error description in ST22 :
What happened?
    The exception 'CX_WDR_RT_EXCEPTION' was raised, but it was not caught anywhere
     along
    the call hierarchy.
    Since exceptions represent error situations and this error was not
    adequately responded to, the running ABAP program
     'CL_WDR_CLIENT_APPLICATION=====CP' has to be
    terminated.
Error analysis
    An exception occurred which is explained in detail below.
    The exception, which is assigned to class 'CX_WDR_RT_EXCEPTION', was not caught
     and
    therefore caused a runtime error.
    The reason for the exception is:
    Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered. Component:
    Z_XXP_PERSONAL_DATA, View: OVERVIEW, Window: Z_XXP_PERSONAL_DATA
Can u plz help me regarding this error.
Thanks,

>Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered
Looks to me like you are trying to fire a navigation plug within WDDOMODIFYVIEW. According to the rules of the WD Phase Model this is not allowed.

Abap web dynpro proxy error

hi all...
i m getting error while testing my abap application.. can anyone pls suggest me, where should i set the proxy settings for that?
error is like this:
Proxy Encountered Error
Host Address Not Found: The proxy could not find an IP address for the host in your request. Possible causes include mistyped URL, misconfigured DNS and transient network problems.
thanks...

1.      Choose Web Services Container -> Runtime -> Settings.
       2.      Enter the required data.
¡        Proxy Host the host of the HTTP server.
¡        Proxy Port the port of the server.
¡        Exclude List contains addresses or parts of addresses, which are ignored by the proxy server. Use semicolons ( to separate entries. You have to add the local IP addresses and domains, which do not use the proxy server. For example, .sap.corp and 10.
¡        Proxy User Name a user name for authenticating before the HTTP proxy server, if required.
¡        Proxy Password a user password for authenticating before the HTTP proxy server, if required.
¡        WS Clients Socket Timeout a socket timeout (in seconds) for the Web service clients requests. By default, it is 60 seconds.
       3.      Choose Save.

Webdynpro proxy page and portal event

Hello there,
is it possible to capture the event from employee search iview into my custom webdynpro ABAP iview?
Since it occurs to me that when a portal page is developed as a "Default page template" I am able to capture the event whenever manager clicks on any employee in the list. But when i create a page with "Web dynpro proxy page" template, I cannot subscribe to the event.
We are trying to use employee search ivew and general data iview provided by SAP plus a custom WDA iview. But when I do a default page template, I am able to caputre the event but general data iview does not show any data...and when I use the proxy page template...I get data in general data iview but I am not able to capture the event....and my custom WDA iview does not show anything...
Employee search iview (previously known as team viewer) and general data iview are standard SAP iviews.
any ideas...
appreciate the help!
Thanks....
J.

Hi Srivastava,
The scenario is like this....
page lay out:
Team viewer iview here----provided by SAP
General data iview here-----provided by SAP
my WDA iview here-----custom iview
if the page template is default template....I get data in my WDA iview for selected employee in the team viewer...but I go not get any data in General data iview
if the page template is web dynpro proxy page...i do not get any data in my WDA iview...but i get data in general data iview...
after debugging this thing...i found that for webdynpro proxy page...the portal event is not getting caught in my WDA iview...
how to subscribe to a portal event if the iview is embedded in a page which is using web dynpro proxy page template...
Just want to share this...that portal eventing is working fine...if the my iview is embedded in a page which is using default page template...
any ideas????
anyone???
Thanks...

Controlling visibility of Web Dynpro Java iView in portal WDJ page

I should be able to use the WDPortalUtils interface in my Web Dynpro Java DC application to get the name of the iView in my Portal WDJ page using IWDPageService method getVisibleIViews(). My intent is to add another iView to this page and programmatically control the visibility of each iView from my WDJ application.
-> Instructions I have found through my online research indicate I should not have to specify a sharing reference because I am using the WDJ framework, but I tried it anyway. It didn't work.
-> I have added DC epbc.prtapi._api public part to my used DC's, and specified dependency at both Build time and Run time.
-> My portal page template is of type Web Dynpro Proxy Page.
-> My iView template is of type Web Dynpro Proxy iView.
-> The Page Content view of my page shows the 'visible' checkbox set for my iView.
The following statements in the wdDoInit() method of my DC's view controller should return the portal name of my iView:
IWDPageService pageService = (IWDPageService) WDPortalUtils.getService(WDPortalServiceType.PAGE_SERVICE);
String[] iViews = pageService.getVisibleIViews();
I get no compile time errors or runtime errors when I execute these statements.
BUT...
Instead of a String array, I get back a memory space pointer.
Example: [Ljava.lang.String;@664e664e
What am I missing?

Hi Jennifer,
That's what this forum is all about; finding solutions to hard-to-solve issues, which might also help someone who may face the same issue in the future. So I hope my input is valuable
The last thing I can think of is the method is been called before the portal page has been rendered completely, which may lead to the faulty results.
Is it possible to move the getVisibleIviews() to a method which is called later in the phase (for instance, at the bottom of wdDoModify or wdDoPostProcessing) or, even better, in an onAction event handler when a button is clicked?
If this doesn't work I'm afraid I'm running out of options and i would file an OSS message with SAP
Hope this helps!
Robin

Portal page template

If I got a rendered portal page and I want to change just the template saving the content, how can I do it???
My question come from the necessary of creating a print template;
from portal rendered page with all my portlets, I need to display just the content and non the applications, so my idea is to change the template of the page and in the new one create only a region for the content and his items too.
Anyone has got a better idea????
Thanks

Hi Praveen,
do you know any internal differences between Web Dynpro Proxy Page and Default Page Template? Because I am using EP 7.0 and it is possible to add web dynpros also to the page created with Default Page Template and they seem to work fine.. The only differences I can see is the slightly different background color of embedded web dynpros and the fact that with Web Dynpro Proxy Page it is not possible for me to set the iView height type to FULL_PAGE (well, it is possible but it does not work)

Tomas

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

Custom Webdynpro Proxy Page Layout

We recently upgraded from NW04 to NW04s. We see the new Webdynpro Proxy Page template.
I successfully created custom page layouts with the default page layouts in NW04.
However, our custom page loyouts do not appear in the drop down list for the webdynpro proxy page, but they do appear in the list for the default page layout.
How do we create a custom page layout for the webdynpro proxy page template?

Yes, you can validate the fields using jquery. Check the status of each field before the validation. Refer to the following post for more information

Display Appraisal Templates in Web Dynpro

Hi All,
I have a requirement to build a Web Dynpro Application that exposes the Appraisal Templates built in the backend to the users.
Can someone guide me as to how I can go about with this. How can I access the Templates in Web Dynpro?

Ashwini.

Hi
As per your question, I understand that HTML output is getting generated through a R3- Bapi call. Fine, create a model with the data binding to the context to some text view. Simply create view with the relevant UI element through which you want to exhibit the data and call the R3 call through your model. instead of a HTML output, you will get your data in the view.
you may not get the exact format / style of the html output.
Otherwise, directly HTML content cannot be shown in webdynpro. You need to have some UI control to take its content.
Or else, you can go in for j2ee stack and end up with a java based appl, use a simple jsp and get the output!
if you have any specific queries do let us know
hope this helps you
thanks

Portal theme not picked for SAP Web Dynpro Iview

Hi,
We have used light framework page for our portal and all the iviews display the content within the iviews in the same set of colors (blue for buttons). However, for a WD java content, I have created an SAP Web Dynpro iView and the contents displayed here appear in the SAP colors without picking those set for the portal.
The same application parameters display the portal colors when we use the Web Dynpro Proxy iview.
Any idea how I can make the SAP Web Dynpro iView appear like the other portal iviews?
Note: The stylesheet property for the iview is already entered (ur), and I have also set the 'Supply Portal stylesheet' property to 'Yes'.
Please provide your inputs.
Thanks,
Vinay

Hi ,
In ABAP Webdynpro for similar problem we used WDFORCEEXTERNAL Sheet property of WDA.
The Web Dynpro framework automatically compares the versions of the portal and Web Dynpro
for ABAP style sheets. If the Web Dynpro for ABAP has a newer version, the WDA style sheet is used. This avoids unattractive rendering and JavaScript errors.You can deactivate this behavior again using the WDFORCEEXTERNALSTYLESHEET application parameter of WDA.See also SAP Notes 1033496 .
If you use the stylesheet of the portal to display the application, the rendering may not appear correctly and Javascript errors can occur(If portal style sheet is lower than WD).
Though Iam not familiar with WD java , the property force portal style sheet in WD java application should be enough to make WD accept portal theme.
