Hi Sami,

Same here.

Actually I am using the link which comes as output in URL field when we test using HTTP client.

The same link I am using in a java code to connect which is giving me 401 error .

Also the same link when i copy paste in browser give same 401 error.

This scenario used to work in PI 7.0 but now we migrated it to PI 7.1.

Hi,

I hope you are using PI 7.1 access to test the http url.

Can you please share the format of URL that you are testing?

The link is

http://<host>:<port>/sap/xi/adapter_plain?namespace=http%3A//rediff/ProjectSTAR/Vendor&interface=SI_...

This link when I copy paste in browser leads to a login popup asking for credentials.

When I enter the proper credentials , It gives 401 error .

Same happens when I use it in a Java code for HTTP connection.

Check the follwoing sap note. I may be helpful:-

Hi Fariha,

I suggest you use a Network packet Sniffer / Grabber and analyze the HTTP Request from the Java Program as well as the Tester and Browser. If you spot a difference in the Request (which i am sure you will), then we can proceed from there.

Refer the below Weblog for more details:
