我正在尝试将Struts 2与Hibernate ORM集成。我在eclipse中创建了一个Maven项目。我添加了项目所需的所有依赖项。我在尝试在Tomcat 7中部署和运行应用程序时收到HTTP状态500 - java.lang.NoClassDefFoundError：com / opensymphony / xwork2 / util / ValueStack。
我已查看此论坛中与此问题相关的所有帖子，其中我发现的解决方案是添加xwork-xxx.jar文件。我添加了xwork2.3.4.1 jar，它是Struts2-core.jar附带的依赖项的一部分。依赖关系已存在于pom.xml中。我还能够在war文件中看到所需的jar文件，该文件是在maven中构建的并部署在tomcat服务器中。但我仍然得到HTTP状态500 - java.lang.NoClassDefFoundError：com / opensymphony / xwork2 / util / ValueStack Exception。
List of Jars in war:
javax.servlet-api-3.1.0.jar
struts2-core-2.3.4.1.jar
xwork-core-2.3.4.1.jar
