Hello team,

AOD version:7.1.0.1202
AAEP version: 7.0.2
Tomcat: 7.0.57

I am using rest operation to connect with the web services but getting error on the Content-Type header. I am able to run these services on google's rest client just fine with the URL, Key and content-Type: application/xml
Not sure whether its the web services that are expecting a different header value in content-Type or is it the rest web service operation.

Here are the trace logs:

Please advice.

Thank you,

For some reason, you get an exception from the Axis stub code when making the request. Did you have some headers configured for the request? They shouldn't be necessary though. Maybe try enable more tracing in the log by setting localsoaptrace=enabled in the data/ddrt.properties to show more detail in the request and response.

The trace logs I has shared earlier was with soap localtrace enabled.
Is there a way to find what is the content-type sent in the request? On the rest web service operation content-type is not a variable that is set, so what is the default value for this header?

There is an existing post on a similar issue that might be helpful to you.
