I'd like to connect to the JMX server on a WebSphere application server instance using a SOAP over HTTP connector but I don't know where to find a compatible SOAP protocol provider.
I get a MalformedURLException when using a JMXServiceURL starting service:jmx:soap:... that says Unsupported protocol: soap. What jar(s)/protocol provider string do I need to include?
Update: I am playing with a standalone Java client.
Unfortunately, IBM only provides a proprietary API to connect with SOAP over HTTP. They don't provide an implementation of the standard JMX API for that protocol. I faced the same issue and I developed such a connector (which is basically a thin JMX compliant wrapper around IBM's proprietary API), which is now available as Open Source. You can find more information here:

The following document describes how to set up a standard JMX tool (VisualVM) to use that connector:

As you can see from these documents, after adding the relevant JARs to the class path and setting the necessary system properties, you would simply connect using wssoap as protocol.
