严重: Error filterStart

解决办法导入commons-fileupload-1.2.1.jar
原因
查看StrutsTest/WEB-INF/lib/struts2-core-2.1.2.jar!/struts-default.xml:46:178得知：
<bean type="org.apache.struts2.dispatcher.multipart.MultiPartRequest" name="struts" scope="default"/>
又由于错误信息
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUploadException
Caused by: java.lang.ClassNotFoundException: org.apache.commons.fileupload.FileUploadException
综上可知：缺少jar包commons-fileupload-1.2.1.jar
?
一般情况下struts工程报Unable to load configuration. - bean - jar:错误，都是缺少相应jar导致
