由于以下错误，我无法在Glassfish v2.1.1中部署EAR：
PWC1270: Exception starting filter struts2
Caused by: Bean type class com.opensymphony.xwork2.ObjectFactory with the name xwork
has already been loaded by bean - jar:file:/C:/Programs/Sun/glassfish_2-1-1/domains
/domain272/applications/j2ee-apps/JabEAR/JabWeb_war/WEB-INF/lib/struts2-core-2.2.3.jar!
/struts-default.xml:29:72 - bean - jar:file:/C:/Programs/Sun/glassfish_2-1-1/domains
/domain272/applications/j2ee-apps/JabEAR/JabWeb_war/WEB-INF/lib/struts2-core-2.2.3.jar!
/struts-default.xml:29:72
耳朵的Web应用程序部分实际上是基于Struts 2.2.3构建的。
我检查了EAR文件，但找不到任何jar重复。我检查了glassfish域lib文件夹，glassfish通用lib文件夹，JDK认可的lib文件夹，struts2-core-2.2.3.jar不存在 怎么可以加载那个罐子？
下面的完整堆栈跟踪：
