Need to be able to specify a proxy

I have tried specifying the proxy in the communicator

<communicator uri="http://selfservice.asp.aurion.com.au/dbcdetst/servlet/services/ev397_aurion_ws?wsdl" credentials="DefaultCredentials" proxy="http://px04:8080" >
</communicator>

I have also tried a value of 'px04:8080' (no http).

Service cannot be started. Unify.Framework.UnifyServerInitializeException: Communicator configuration unknown setting of proxy ---> Unify.Framework.WebServiceCommunicatorException: Communicator configuration unknown setting of proxy ---> System.ArgumentException: Incorrect value proxy attribute in <communicator uri="http://selfservice.asp.aurion.com.au/dbcdetst/servlet/services/ev397_aurion_ws?wsdl" credentials="DefaultCredentials" proxy="http://px04:8080"></communicator> ---> System.ArgumentException: Requested value 'http://px04:8080' was not found.

Service Starts. Now getting...

Hi Peter,

Can you try changing it to "custom" and adding an additional attribute called "proxyUri" with the URI?

Furthermore, if you need to specify some credentials, change "DefaultCredentials" to "Custom" and use "domain", "user" and "password"/"securePassword" attributes to specify credentials accordingly.

Sorry that this isn't more clearly documented, it's a base communicator used for many connectors and I'm not sure where the information is.

The communicator configuration details should be the same as those for the TRIM connector IDBTRIM305:Communicator

Thanks guys - a lot further then before. I'm now getting two separate errors.

The employee connector gives:

I'm fine if the user has no rights but the different error from the employee connector I have no idea on.

Configuration

<communicator uri="http://selfservice.asp.aurion.com.au/dbcdetst/servlet/services/ev397_aurion_ws?wsdl" credentials="Custom" domain="dept" user="svc_im" securePassword="wJL6UplhBBEgc6WbWeTYC+5Wc+uQV3HyDUog6260O5I=" proxy="Custom" proxyUri="px04:8080">

Ignore me - I only changed Employee. The Security User one doesn't have the credentials in it yet so that error is fine.

This seems to indicate that you need to put the protocol (http/s) at the front - could you try that?

That worked. I'm now two more steps along.

I have used Custom credentials and got 407: Authentication required.

I reconfigured the service to use an account that would have rights to the proxy and used Default Credentials got 407: Authentication Required.

I have no found the address of the unauthenticated proxy at DBCDE and now get:

502 shouldn't be our problem but I can't get any further diagnosing the problem.

No rush on this today - I have to leave to do an install at Environment so I won't get a chance to get back here until Monday.

Sudden thought: Would the service timing out produce a 502 when viewed through the proxy? Very possible. I'll do some research on that over the weekend.

Not sure - I've seen HTTP errors (500) before with timeout problems, but I don't think 59 seconds would be long enough to trigger it.

I'll keep looking at all the material you've provided and see if there's anything I can do. If not, I'll at least be ready on Monday to respond to anything we come up with.

Hi Peter,

Has there been any more progress with getting this issue resolved? I've had a brief look but it seems to me that the web service communicator is providing all the options required to account for a proxy server. Unless a clearer problem can be defined I'm not sure what technical change I could make to help you.

Resolved with the following:

• Set URL to https://
• Set Authentication to NONE
• Set proxy to Unauthenticated proxy

Communication established successfully.
