WebDynpro development : KM reference - PortalApplicationNotFoundException

Hello All,
I have created a WebDynpro application where i would read an XML in KM folder and display the content.But, when i *** the sharing reference "PORTAL:sap.com/com/sap.km.application" as WebDynpro sharing reference, i get teh application but with warnings. When i open the message, i see the PortalApplicationNotFoundException.
I have added the JARs bc.util.public_api.jar,bc.sf.framework_api.jar,bc.rf.global.service.urlgenerator_api.jar,bc.rf.framework_api.jar,com.sap.security.api.e p5.jar.
I would like what could be the cause, our team had used the same reference in previous project.

Thanks & Regards,

Hi Sharath,
the SharingReference should point to PORTAL:sap.com/com.sap.km.application.
Not to PORTAL:sap.com/com/sap.km.application.
Hope this helps.

WebDynpro development vs. ports and IE security settings?

Hi!
We have Sapgui running in a Citrix server and its hosted there for multiple developers. The backend they access is SRM where they need to do WebDynpro development work.
Problem is that when going to the WebDynpro editor screen and choosing the layout tab they can see only a blank page!
What are the requirements for the WebDynpro development workbench in terms of:
- Ports required open between the Citrix host machine and SAP server? We have already opened ports 32nn and 80nn.
- Internet Explorer settings that should be looked at? Security settings that must be enabled?
- Any other settings in host or client side that needs to be checked?
Thanks in advance!

you are sending back the wrong mime-type + it appears that you are not using response.close after streaming back the image in your asp.net code behind.

ensure Internet Options>Security tab, click "Reset all zones to default"... (IE has security settings for mime types) and also that Tracking Protection is turned off for the site (Tools>Tracking protection)

Webdynpro Development Component Callable Object Escalation

Hi,
In gp sequential block workflow using webdynpro development component callable objects When the initiator intiates a workflow ,it is assigned to the first approver.Now if the approver does not take any action within 2 days i want to escalate the task to the second approver.How can i do this escalation?
There is a standard parameter call due date...in action.How can I set this value dynamically from my application..
During escalation , the next approver has to be taken by executing an rfc in the background
Please help....
Thanks,
Shamila

Hi,
You can define a CAF Core application service (implemented in the CAF Core layer) or a background CO (implemented by a J2EE class interface) which can call a RFC to get the next approver and return the next approver's user id as an output parameter. You can use dynamic user assignment in the next action (approval), by selecting the processor as "Filled From Context Parameter" (at the Roles tab in block level) and select the user id output parameter of the background CO/CAF app service CO.
You can get more details on different types of CO at the CAF Tutorial Center @SDN

Technical specification template for WebDynpro development required

Dear All,
Can you please provide any pointer to SAP provided technical specification templates for WebDynpro development.
Thanks and regards,
Sudhir

Hi Sudhir
Does that mean you got the documents you were looking for?
I too am looking for sample documents and/or templates for Technical Specification for WebDynpro (Java) Application but was not able to find any.
If you have them will you please forward them to me?
If you can share a tech spec done for a real project (or even a sample one) along with any such documents, I'd much appreciate it as I'm new to the technology. I still have to find my way around these..... :o)
Thanks in advance.

Webdynpro development for portal integration

our requirement is to run the adoe interactive form in enterprise portal and store the entered data in SAP system.
Can i develop in NWDS (call LIfecycle designe inside) and create webdynpro object by selecting new project as
1) webdynpro project or
2) development component project and type as webdynpro and select domain is Enterprise portal etc.,
which one is correct way for webdynpro development and deploy in . If I select the 2nd option, how to deploy it.
Please advise
Thanks
Gopal

Hi Gopal,
EP7:
Expand the local and sap.com webdynpro components.
You will see your WebDynpro DC in "sap.com" which is the default vendor while creating a DC.
After you found the DC select an application and follow the other steps to create an iView.
If it is WebDynpro Project then you can see that in local.
If you are using EP6 then follow the document:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3e36d690-0201-0010-cd99-bfbb81bd33d9

WebDynpro development in GP: only WD java ?

Hi,
I want to develope a custom webdynpro component that can be used as a callable object, may i choose Webdynpro for ABAP as the development tool? I noticed that in some tutorial that certain APIs are necessary to develop webdynpro component, does that mean Webdynpro for JAVA is the only option?
thanks and best regards.
jun

Hi,David,
We are seeking a development tool that is more easy for our abap developer to learn and integrated into GP.
So according to library, WD for abap has following limitation:
Currently only input parameters of type String are supported and it is not possible to add input parameters. You can only change the order in which the parameters are displayed.
then how about BSP? I read the library, and it does not mention such limitation, and it seems that BSP can return status back to GP. So, for callable objects whose logic are in R3, is BSP a good choice?
thanks and best regards.

         Public Parts
         External files used

        iii) Methods of Component - Each method explained separately
        iv)Message Pool
        v) Views - Each view explained separately with methods written, plugs, events
         vi) Windows

Hi ,
Are you editing ESS WebDynpro applications ? If its a error in the standard component its a product issue and u can raise a OSS message.
But I doubt , you have edited the same.
In that case , can u post the code in FcPersonalInfo s interface controller 's onCleanUp function.

Webdynpro development standards

Hi All,
Does anyone knows whether there are any development standards recommended for Webdynpro (WDJ or WDA) development?
Thanks, Jin

Hi,
for WDJ, ask in the WDJ forum.
For WDA, see the [documentation|http://help.sap.com/saphelp_nw70/helpdata/en/81/809d4e09f84eb98103c4317c9ee9a5/frameset.htm]

Problems with initial setup of Java WebDynpro development environment

Hi Experts
I am very new to Java WebDynpro environment. I am trying to setup the J2EE engine and SAP Netweaver Developer Studio on my local machine. I have installed MaxDB, SAP NetWeaver Developer Studio and NW2004s on my local machine. After this I have started my server node from SAPMMC. I have following doubts to be clarified:
1. How do I know the Message Server Port number of the SAPJ2EE engine which needs to be specified in the SAP J2EE engine settings in Developer Studio.
2. How do I make sure that my server process are properly started and running properly?
Best Regards
Anand.

Hi Arun
In my SAPMMC, I am seeing two instances under my server node running in green status. I assume that one is J2EE instance and other in SCS Instance. J2EE instance number is 30 and SCS instance number is 31. I tried to access the links:
http://localhost:53000/index.html and
http://localhost:53100/index.html
I was unable to access both these links. However when I tried to access only
http://localhost/index.html , I got the SAP Web Application Server Homepage. Here on clicking the System Info link, it asks for user/password. The default user/password can be used as Administrator/abc123.
Here I got all the info about my server ports.
For me http port was set as 80 and thatswhy 53000 and 53100 were not working for me.
Thanks a lot for your help.
Cheers & Best regards
Anand.

Standards to follow in webdynpro developement and how to transport ??

hi , i want to know
1) the best programming standards to follow while developing a webdynpro component or application..
2) how to transport a developed application ..?
plz help me..
thanks in advance..

1) there were so many best practices ...so better check below links
http://www.sdn.sap.com/irj/scn/index?rid=/media/uuid/40523a47-5dac-2d10-42a4-d7d234d95fd4
http://community.altiusconsulting.com/blogs/adamadshead/archive/2009/12/17/sap-web-dynpro-best-practices.aspx
2)
To transport a developed application we have to move corresponding transport request number to quality then production.
to transport, open se09, click on F5 then provide the transport number...click ok..
now press F9 to release the transport the request number from development.
Now that request wil be in quality or production( depends on ur company landscap ).
ask your basis team to import that request into quality. he will do it using STMS tcode.

Srinivas
