Hi Everyone!

I have a question about an error that 1 in 10 times occurs when I use an HTTPS web service created in .NET, does anyone have any idea why I have this error on some occasions that can help me? thanks.

Hi Antonio; Its easy to change ... just replace your SOAP library with the .NET SOAP one ... for example: pbsoapclient190.pbd => pbwsclient190.pbd After that, redo (rebuild) your WS "proxies" via your PB "Proxy" project and then re-test. HTH ... Chris Note: Change 190 to nnn that matches your PB version.

Hi, 

Here is an example http://powerbuilderworld.blogspot.com/2012/09/calling-web-service-from-powerbuilder.html

How to Call a Web Service using .NET instead of EasySoap.

Hi Antonio;

  Can you tell us ...

1) Is the .Net Web Service built in PB or VS?

2) Which side gets the error (WS or PB client)

3) Do you automatically retry the WS call? If so, does it work OK the 2nd time?

4) What PB feature are you using to interact with the WS?

Regards ... Chris

Hmmm ... EASYSOAP is the very old WS protocol (circa PB v8.0). PB also supports .NET Soap as well (circa PB v11.0). That should be transparent and might work better. The latest releases of Appeon PB can now use HTTP as another option but, that would require some code refactoring.

Thanks Chris!!! Can you give me some example to do that, how to invoke a web service, in the way you tell me?
