Mule SAXParseException: cvc-complex-type.2.4.a: Invalid content when running Flow with propietary Connector.

Question

I've developed a connector, with Jersey, Jackson and OAuth 1. The connector project builds ok with Maven, then I install it in my Mule project, included it on a flow and when I run the project I get:

    Invalid content was found starting with element 'g4:config'.

The XML of my Mule project is:

<?xml version="1.0" encoding="UTF-8"?>

        <g4:test-rest config-ref="G4" id="123" doc:name="Intelisis G4 Connector"/>
    </flow>
</mule>

I've been stuck in this for two days and don't know what else to do.

If you need the XML of the connector (or the Java), please let me know.

Thanks for your help!

Answer 1

You need to configure the mule maven plugin to include your connector when the application zip gets created. You can refer to the salesforce connector as an example
