12.6 PB Web Service Client .NET ENGINE TLS 1.0 PROBLEM

Hello we are developing a client for cosumming a WS.

The problem is that our firewall, ZScaler does not allow communications over TLS 1.0 (deprecated since 30th June 2016) , so we always get a sopa Exception because of emptty response(zScaler does not send the content to us).

The ws client is a .NET engine client.

Anybody knos how to solve this? Is thaere any possibility for working with the sopaconnection object using tls1.2?

    Hi Juan;

    Until Appeon can address PB's Web services deficiencies, I wonder if using a 3rd party control or a callable Java Class to broker the WS interaction might be the way to proceed?

      Hi, thanks a lot Chris...

      We have already tested with a.jar class and also with activeX. Both are good solutions and Works fine.

      For us is more "comfortable" to work with a PB client, and now we are trying to get permission of our company to use soap 1.0 through Zscaler at least for the domain of the WS.

      In order to ensuere a long lifwe solution, I asked if there is prevssion from Appeon of implementing TLS1.2 versión in nexts builds/versión.

      Thanks a lot again for your help, Chirs

    Hi Juan,

    we had also the requirement to use a webservice with TLS 1.2.

    Our Solution: We built a .NET assembly to use the webservice using .NET and use that via COM. You must use .NET 4.5 Framework because TLS 1.2 is not implemented in previous versions.

    You can use WSEWSDL3.EXE (part of Windows SDK 7.1) to build a class for WSDL. You have to extend it to set the security protocol:

    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

    For more information about build and use a COM object for an assembly look for Bruce Armstrongs detailed description: Using .NET Assemblies with PowerBuilder
