Question

When I run this:

<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns="http://www.mulesource.org/schema/mule/core/2.2"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <inbound>
                <http:inbound-endpoint host="localhost"
                                       port="9000"
                                       synchronous="true"/>
            </inbound>
            <outbound>
                <chaining-router>
                    <outbound-endpoint address="https://localhost"
                                       synchronous="true"/>
                </chaining-router>
            </outbound>
        </service>
    </model>
</mule>

I get this:

Answer 1

You need to explicitly configure the HTTPS connector with a client keystore so you can make outbound HTTPS calls. This is explained here (free registration required to read this doc).

In essence, it boils down to this:

<https:connector name="httpConnector">
    <https:tls-client path="clientKeystore" storePassword="mulepassword"/>
</https:connector>
