无法读取架构文档'；http://www.mulesource.org/schema/mule/core/2.2/mule.xsd'

我正在尝试使用http端点和JMS连接器执行一个简单的JMS程序。 但我的错误信息越来越少。请帮我解决这个问题

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.mulesource.org/schema/mule/core/2.2/mule.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>.
