我无法从MuleStudio启动Mule应用程序。有什么指针吗？
这是我的Configuration xml：
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
xmlns:spring="http://www.springframework.org/schema/beans" version="CE-3.4.0"

xsi:schemaLocation="http://www.springframework.org/schema/beans http: //www.springframework.org/schema/beans/spring-beans-current.xsd

http: //www.mulesoft.org/schema/mule/http http: //www.mulesoft.org/schema/mule/http/current/mule-http.xsd">
<flow name="testFlow1" doc:name="testFlow1">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>
<logger message="testing" level="INFO" doc:name="Logger"/>
</flow>
</mule>
....这是我得到的例外
