Error Message: Application not found

[Former Member]

Hi,

I have got a problem with my developer studio. If I want to run any webdynpros, there appears the message "Application not found". I do not know how it happened, before yesterday it worked very well and I did not change any settings.

who can help me?

Hi,

Can you logon to your portal and navigate to Content Administration->Webdynpro. Check if the application that you are trying to run is present there. If it's present there try running it from there. If not then try redeploying your app.

Regards,

Satyajit.

Hi Satyajit,

I tried to run it from the portal (it is in the content, so rebuilding function worked). I get the following error message if I try to run the appl. from the portal:

An error has occurred:

"Failed to process the request."

Please contact your system administrator.

Manuel,

Are you using ViewContainerUIElements? Does your application has a view called Empty_View? Are you trying to show it in more than one places, say in different UI elements?

Regards,

Satyajit.

[Former Member]

Yes, I used it in different places. I changed it and now it works if I start the application from the portal. Thank you for that. But I have got the same problem, that I can not run any applications in my developer studio.

[Former Member]

Hi Manuel,

When you launch any application from the NWDS, can you note the URL from the browser address field? Does it seem to be correct?

Then try launching the same URL in a stand-alone browser session.

Regards,

Satyajit.

[Former Member]

I copied the link into a stand-alone browser and the application appeared correctly. It seems that there are some wrong settings in my NWDS. This is very strange, because I did not change anything.

Do you know what I can do?

[Former Member]

Hi,

Can you share the URL that results out of your NWDS?

Regards,

Satyajit.

[Former Member]

Hi,

Try undeploying your application from the DeployTool utility. Then do a redeploy from the NWDS.

Regards,

Satyajit.

[Former Member]

Hi Satyajit,

Can you tell me how to undeploy an application?

By the way, the problem appears in every webdynpro, I created a completely new one and the error occured already after the first build and deploy.

(also after I uninstalled and reinstalled the NWDS)

regards

Manuel,

Go to C:\usr\sap\<server>\Shortcuts and launch visualadmin.bat. Then navigate to <ServerName> -> <ServerID> -> Servives -> Deploy.

Under deploy service, expand "Server" -> "WebDynpro" and choose the WD application that you want to remove and press "Remove".

Hi,

I did that and rebuild the project again. It does not work. Always the same problem, if I want to run my webdynpro in the developer studio: "Application not found"

With the copy of the link into a stanalone browser, it works.

I hope that I do not have to remove my whole portal.

regards

Manuel,

I guess, something got corrupted in your NWDS. So, create a new project with the same name under different workspace, and copy the "src" folder of the actual project to the new project that you created. Then do a "Reload" (+Rebuild).

Deploy the application then..

[Former Member]

hi Bala,

I can create as many new projects as I want, I always got this error.

greetings

manu

[Former Member]

Manu,

By the way, where do you see the error message..In "Deploy Output View" of your IDE??.

Go to "Windows -> Show View - > Other -> PDE Runtime -> Error Log"..and post the stack trace..

Bala

[Former Member]

Bala,

there are not any errors during building and deploying of the webdynpros, so no error in the error log.

the error occurs (pop up window) during the run of the applications in the developer studio.

The popup window in the NWDS shows me the link to my application:

http://pta1315:50000/webdynpro/dispatcher/local/WebDynproQuiz/QuizApp and the information: Application not found.

maybe something is wrong with the path of the developer studio, but I did not change anything an last week it worked very well

[Former Member]

Hi,

Can you start your Visual Administrator and check if your application is started?

Regards,

Satyajit.

[Former Member]

Hi

Rebuild your project. Other wise close and open Webdynpro. Last choice to Relod(Relod+Rebuild) your project.

Kind Regards,

S.Saravanan.

[Former Member]

still the same problem, I do not hope that this was my last choice 🐵

[Former Member]

Hi,

Are u running your application from portal and getting this error message? OR while deploying you get error?

Kind Regards,

S.saravanan
