How to use a debug proxy with hybris and datahub?

[Former Member]

I need to use a debug proxy to see the REST calls between hybris and datahub.

Normally you can get java to use a proxy by specifying the parameters:

 -Dhttp.proxyHost=localhost -Dhttp.proxyPort=8888

e.g. as JAVA_TOOL_OPTIONS environment variable. In Maven it will need to be put to the configuration of the tomcat7 plug-in.

I have been trying different things that I could find via google for hybris and datahub and neither of them would use the proxy. Did anyone do that yet and knows how to do that?

Have you considered a debugging proxy tool like Fiddler or Charles and just pointing the Datahub or hybris side directly to the proxy to see the request contents? i.e. datahub.extension.exportURL=http://localhost:{fiddlerport}/ or datahubadapter.datahuboutbound.url=http://localhost:{fiddlerport}/datahub-webapp/v1

Also, Wireshark can capture the messages as well.

I am using Charles. But pointing datahub or hybris to the proxy directly is not bringing me very far as I can't see them talking to each other, I see only one initial post. And sure, I could use Wireshark, but generally it's not really hard to get java to go through a proxy, just in these cases there are wrappers that start the jvm and I need them to use the proxy parameters.

I've also experienced issues setting a proxy with JVM parameters in hybris. Although advice is quite good and I've used it to see requests between hybris and datahub. With Fiddler you can root incoming requests to a new port so it allows to keep communcation between hybris and the datahub AND tracking request in Fiddler. To do that in Rules->Custom Rules, edit the OnBeforeRequest method and add if (oSession.host.toLowerCase() == "localhost:8888") oSession.host = "localhost:8080"; (Fiddler is listening on port 8888 by default)
