JAR包不全！Unable to load configuration.-bean-jar:file:/.../struts2-core-2.2.1.jar!/struts-default.xml:7
【现象】
eclipse+jetty启动一个java web工程的时候，报错如下：
2015-09-06 13:29:22.884:WARN::failed struts2: Unable to load configuration. - bean - jar:file:/D:/jars/omch_hubei/struts2-core-2.2.1.jar!/struts-default.xml:71:140

【原因分析】
工程没有使用maven库，所有jar包都在自己创建的user library下。
使用的是struts-2.2.1，怀疑是引用的jar包不全。
【解决办法】，查看用到了哪些jar包。
查看struts2自带示例程序struts2-blank.war，用rar解压后会看到用到了如下基本的jar包：
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
freemarker-2.3.16.jar
javassist-3.7.ga.jar
ognl-3.0.jar ----------------------------------->>>> 我少的就是这个。添加到自己的user library下，重新编译，就OK啦。
struts2-core-2.2.1.jar
xwork-core-2.2.1.jar
另附struts2-core-2.2.1.jar编译打包用的pom.xml
