This error occurred while I was following Lab 5 of the Mulesoft partner workshop. After I got a project template from exchange and run it as mule application, following error occurs.
WARN 2017-01-30 15:04:41,778 [main] org.springframework.beans.factory.xml.XmlBeanDefinitionReader: Ignored XML validation warning org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.mulesoft.org/schema/mule/objectstore/current/mule-objectstore.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) ~[?:?]
I found an answer from the mulesoft forum as follows
Just curious, have you installed the object store connector in your AnyPoint Studio?
Coming from BizTalk background, I thought the error message suggests that my configuration for mule app was somehow screwed but it wasn’t. Installing objectstore resolved the issue.
