Enable HTTP/1.1 support in Cognos SOAP SDK to prevent “426 Upgrade Required”

We are currently unable to call CACC (Cognos Analytics Certified Containers) ServiceMesh endpoints via the Cognos SOAP SDK because the requests fail with HTTP error 426 Upgrade Required. The root cause appears to be that the ServiceMesh URL requires HTTP/1.1, while the Cognos SDK still relies on an outdated Axis library that only supports HTTP/1.0.

There is already a newer library available, org.apache.axis2, which supports HTTP/1.1 and would technically resolve this limitation.

I would like to request that the Cognos SDK be enhanced to:

  • support HTTP/1.1 for SOAP calls to modern endpoints such as CACC ServiceMesh, and

  • replace or upgrade the current legacy Axis implementation with org.apache.axis2 (or another HTTP/1.1-capable client library).

This enhancement would:

  • remove the 426 Upgrade Required error when integrating with CACC,

  • modernize the SDK’s HTTP stack, and

  • improve compatibility with current and future Cognos Analytics containerized deployments.
