Hello rakesh16d

Do you have multiple front ends? Are they load balanced?

If you have the webservice on one of the front ends, the one which you are testing the form on, then it will preview ok. Once it's published, and if the webservice isn't on all of the front ends, in the same location, then it will fail.

Regards,

Robbie_Leggett

:-)

I was able to do it by using the correct username and password.

Thanks
rakesh

 

by: Robbie_LeggettPosted on 2009-07-01 at 00:52:33ID: 24752259

The webservice would be inaccessible when previewed if you were using an incorrect username and password.

NO I was previewing it on development server and i am admin on tht server so everything worked fine there. but when i published my web service on my application server and user tried accessing it from the web frontend it never worked. so I added the authentication to the web service data connection and added the admin username and password to it and its working very much fine now. :)

 

by: Robbie_LeggettPosted on 2009-07-01 at 04:48:22ID: 24753278

The example of the webservice you gave had no indication that you were using some sort of passthrough authentication. It actually states "use explicit". Of course it was assumed you were using an account with access rights as you specified explicit credentials.

Out of interest, when you published the form, which explicit credentials did you provide?

:-)

 

by: rakesh16dPosted on 2009-07-01 at 04:51:42ID: 24753295

I was using mine and i am not admin on the servers. But we have one that we use for other purpose and that ID is admin on all the three servers. I never used explicit credentials on the development server as i am admin there. I only used these explicit credentials when i published it on the production server and that resolved my error.  :)

It's worth mentioning that next time, if you use a different connection string for a successful connection than the one you use for an unsuccessful connection, then ask a question revolving around the unsuccessful connection, it's worth mentioning you used a different connection string.

:-)

Thanks for the suggestion :)
