IView Personalization (Web Dynpro Java) for Anonymous User

Hello All,
Is it possible for anonymous user to see iView personalization (Web Dynpro Java) when personalized by an administrator? What I did was create new role and iView making available to anonymous user. This work fine meaning I can view iView using URL http://<servername>:<port>/irj/portal/anonymous . But the personalization I made to iView using administrator mode launching iView in preview mode and then using personalization dialog by choosing Ctrl and secondary mouse button to personalize is not showing. Iu2019m currently on EP7 SP15 and using iView type Web Dynpro Java for the development component sap.com/tcsecumewdenduser application name LogonHelpApp.
Any help is very much appreciated.
Many Thanks,
Gary

Hello Michael,
Yes, the Web Dynpro for Java Personalization is working perfect for non-anonymous users. The issue is when I view same iView using anonymous URL http://<servername>:<port>/irj/portal/anonymous the personalization is not showing just defaults back to the original Web Dynpro Java application settings. The iView that I created and personalized is the new Logon Help Dynpro Java application (LogonHelpApp). Is there some permissions that restricts anonymous user to view personalization?
Koti Reddy Iu2019m using the Web Dynpro for Java Administrator Personalization. Here is the documentation [http://help.sap.com/saphelp_nw70/helpdata/en/42/ed3ce7f8593eebe10000000a1553f7/frameset.htm |http://help.sap.com/saphelp_nw70/helpdata/en/42/ed3ce7f8593eebe10000000a1553f7/frameset.htm ]

Problem of refreshing a tree in web dynpro java

hi all,
I'm facing a problem for refreshing a tree in web dynpro java for SAP HR.
I created a viewset with 2 cells( 1 view for each).
In the 1st view I created a droplistbyindex to select the unit ID and in the 2nd view ( defaut=false) I called a method to populate my tree according to my selection in the 1st view ( method called in wdInit).
When I make the first selection everything is ok.
But when I select another unit ID, the tree is not changed and I know the context is well changed according to my selection.
So I think the method is executed only the first the view is called.
In this case, how can I refresh my tree on real-time?
Thanks for your help

May be u can write the code wdDoModify instead.

Web Dynpro Java : Failed to get deployable object part info for component

Currently we have a web dynpro java project which connects to the ABAP backend with Web Services. Everything seems fine, and when we transport to the production server via NWDI, we have the following error. Everytime we try to access the application , the error is occurred.
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to get deployable object part info for component com.sie.attachmentcomp.AttachmentComp
    at com.sap.tc.webdynpro.clientserver.cal.ClientComponent.getComponentDeploymentDescription(ClientComponent.java:784)

    at com.sap.tc.webdynpro.progmodel.components.ComponentUsage.createComponent(ComponentUsage.java:116)
It is working properly in our development , and testing environment. Only production has this error. And one weird thing is that this particular error occurred only sometimes to some user. For example; I could not access to the application with this error yesterday but my friend can access. Today, I can access in the morning but my friend cannot. For another friend , Yesterday he can access by using IE but not by Firefox. But today Firefox is fine but not with IE. It seems crazy.
For more information, in our J2EE engine for the production server, we have 3 server nodes (clusters). And we are not sure it is the source of the problem. Is there any solution , and any way to know from the application that we are on which server?
We also go and check from the Content Administrator in Web Dynpro Console. Under our project name, in the list of Components, sometimes we can see AttachmentComp but sometimes not.
Please help us as our project is about to go-live next week.
Thanks,
Yu

Problem: Changing Language for Web Dynpro Java within NW Portal (i18n)

Hi Experts out there,
I hope all you had a nice Christmas and a big New Years Eve :)!!!
i got a challenge for you about WD Java and internationalization (i18n)
Here is the scenario:
We are using a SAP NetWeaver Portal 7.0 and my task is to implement some smaller Web Dynpro Applications.
These Applications must be i18n conform, so i just created (according to the corresponding WD Java tutorial) some ".xlf" files.
Okay...Everything is working fine. The user can log at the portal and the application is displayed in his language, which is "english" or "german". (the application is just a simple form)
So far so good...Now here comes the point where it's getting tricky...
When the user wants to change his assigned language (of the portal user) he can use the "personalize" button in the Masthead (-> change portal language). All the portal content should now be displayed in his new chosen language.
For example the user is logged into the portal with "german" as portal language and now changes his languages settings into "english". After this everything in the portal (navigation, portal iViews ) is displayed in the changed language (from english into german) ...
BUT: my Web Dynpro Java Application stays as the original languages setting was. That means the whole portal is now english, but my WD Java Appl. stays german .
Only if the user logs of and logs in again, the WD Java Appl. is displayed in the corresponding portal language...
VERY Strange?!?!
Can anybody give me a hint how to solve this problem?
I guess i have to re-initiate the Web Dynpro Application some how ...(like killing the application and restarting it ...) but is just a "weak guess"...
Any Help / Hint is more than welcome !!!
Cheers
Stefan

Hi Stefan,
This correct see SAP Note [947081|https://service.sap.com/sap/support/notes/947081]
If the locale for the Web Dynpro iView is changed in the portal (through portal personalization), this is not reflected in the running login session. The user needs to logoff and login again, in order to see the locale change in the Web Dynpro iView.

Leo

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
    I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
     procedure"
   Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
     signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

Hi everybody,
I have been reading some documentation about what is the best option to create an application for handheld device. So this is my landscape. I have SAP Netweaver 7.4 SR1 AS ABAP, and Java instance. So, I want to know whether is possible to create a normal web dynpro java application and then visualize this application on Browser of handheld device. That's all that I have to do? I read that exist another solution Developing mobile application for handhelds. By other side a need to know how to is the integration of this device with this application if exist. This application is going to consume data from SAP Backend system, so I just have to create JCO's for connect this application to this system, right?
Please, can you help me with that.
Best Regards.

Hi Deepti,,
Refer to the following thread which says that you must retrieve the data from the CRM backend system using standard BAPI's or customer Remote enabled function modules (socalled RFC's) and to access the backend system you will have to set up an RFC connection with CRM system.
Regarding web dynpro and CRM

Hi,
Web Dynpro is the SAP programming model for user interfaces (UIs).
It provides a programming framework within which you can achieve a:
u2022 Clear separation of business logic and display logic
u2022 An application specification that is both:
Client neutral and
Backend neutral
It consists of a runtime environment and a graphical development environment with special Web-Dynpro tools that are integrated in the SAP NetWeaver Developer Studio
The Web Dynpro technology provides a development and runtime environment for Web applications and enhances classical Web development to build easily adaptable user interfaces. SAP's Web Dyn-pro technology closes significant gaps between typical Web development tools and the needs of cost-effective, responsive, easy-to-use, maintainable, and professional browser-based user interfaces for business solutions. Web Dynpro uses design principles similar to SAP's Dynpro technology, but it is a completely new technology geared exclusively towards Web applications. Its main features include the following:
u2022 Usability
u2022 Abstract modelling
u2022 Personalization and customization
u2022 Separation of presentation layers and business logic
u2022 Generic services
u2022 Portability
Web Dynpro applications run in the SAP Enterprise Portal.
See https://www.sdn.sap.com/irj/sdn/nw-ui for more information.

Advantages and dis advantages of web dynpro java

Hi Guys,
May i know what are the advantages and dis advantages of web dynpro java?
Regards,
Madhu

Hi Madhu,
Web Dynpro (WD) is a proprietary web application user interface technology developed by SAP AG and exists in a Java (Web Dynpro for Java, WDJ or WD4J) and an ABAP (Web Dynpro ABAP[1] , WDA) flavor. Both have in general the same functionality, but usually one flavor is improved after the other, so temporary one flavor is more advanced than the other. Hence, the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
WD follows an adapted MVC pattern and a model driven development approach ("minimize coding, maximize design") with a large number of dedicated hooks in generated code to place custom coding. It is intended for business applications that shall follow standardized UI principles, connect to backend systems and be scalable.
Main advantages of Web Dynpro over other technologies
typed access for design time checks, e.g. navigation links and messages are accessed via types instead of string keys like in JSF
diverse services for backend access, like aRFC, JEE and Web Service data models
integration with SAP Interactive Forms by Adobe, which are interactive PDF forms, during design (same IDE) and run time (data sharing)
integration with business process management and business rules management (since NetWeaver CE 7.1 EHP 1)
designed to support development big scale applications by adding multiple grouping layers on top of Java packages (DCs, SCs, products)
runs on different clients e.g. web browser, mobile device, widget engine
comes with a big collection of UI elements providing a wealth of functionality and only have to be configured but not programmed
Main disadvantages
proprietary, running only on SAP servers
less flexible due to support for multiple clients (i.e. custom html is not possible). To reduce the limitations, several measures have been taken. For example, WD supports so-called "islands" for e.g. flash applications that enrich the Web Dynpro UI element collection by rich UI elements. This disadvantage doesn't seem so serious but in fact basic features that user expect to receive cannot be implemented (e.g. coloured rows in table, colours in general, advanced aligning of simple UI elements (due to nonexistence of more complicated ones), selecting multiple rows in tree-like tables (this is due to preserving basic concept of WD) and many more). Having the flash feature means that developer completely avoids WD UI (And thus cannot use other features).
rendering speed in browser for larger tables (>1000 rows)
The designtime and runtime environment is part of SAP NetWeaver 7.0[2] (also known as Netweaver 2004s) and following releases.
The name comes after the original Dynpro library, whose name meant "Dynamic Program".

Pradeep Kumar

Logical Destinations in Web Dynpro Java

Hi!
Is it possible to access logical HTTP destinations maintained in SAP NetWeaver Administrator via Configuration Management -> Security ->Destinations in Web Dynpro Java source-code.
I would like to use such a destination to configure an URL target for a IWDFrame UI element.
Thank you very much in advance!
Regards,
Thomas

I found out that there is a [Destination Service API|http://help.sap.com/saphelp_nwce711/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm] for this purpose. Unfortunatly I am still not able to provide the required components security.class and tc/sec/destinations/interface to the web dynpro component. Maintaining them via Project Properties -> Web Dynpro is not allowed any more, and I couldn't find them in the DC perspective to add them as DC dependency.
Has anybody got an idea where these two libraries have gone?
Regards,
Thomas
PS: The 7.0 procedure, which can be found in various posts, doesn't seem to work any more for CE 711.
