Have you configured the proxy settings in Eclipse? I believe the SimpleProxyServlet used the Eclipse Authenticator.
Internet Servers
The SimpleProxyServlet can be configured for proxy requests to internet servers in the same way as for intranet servers. Additional proxy settings may be necessary.
As the SimpleProxyServlet automatically uses the proxy settings from your Eclipse this can be configured in Eclipse under
, and select . Here you can specify the proxy entries and the proxy bypass.For example, set Active Provider to Manual, Schema=HTTP, Host=proxy, Port=8080 under proxy entries and localhost, *.sap.corp as Host under proxy bypass.
