Invalid Response Code: (407) Proxy Authentication Required

[Former Member]

Hi all,

I have created a EJB that will access an external webservice to receive data and will display it in a jsp. But when i call it, i get the folllowing error-

com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeExcpetion: Invalid Response Code: (407) Proxy 
Authentication Required (The ISA Server requires authorization to fulfill the request. Access to the Web Proxy is denied)

I have already set the proxy user name and password in <i>visual admin</i> under <i>destinations</i> and also under <i>Web Services Container->Runtime->Settings</i>. Still i get this error. I checked a couple of threads here, that answer to my problem, but none helped! Am i missing something?

Thanks in advance,

Swarna

You are using Microsoft ISA server as the Proxy?

If so, I new rule may need to be put in place on the ISA to allow the communication to go through.

Hi Swarna

What is the patch level that you are running on?

May be the "auth-scheme" element required by the HTTP specification is missing in the "Proxy-Authorization" HTTP header.

I think that the solution is there in the new support packages or the patch update.

Please check out the latest support packages and apply them.

This should solve your problem.
