500 errors reported after the first consolidated struts2+spring submission form

SPRING+STRUTS2 integration, do a user login test program, with the configuration file fragment
<constant name= "struts.objectfactory" value= "Spring"/>

<package name= "Struts-config" namespace= "/" extends= "Struts-default" >

<action name= "Login" class= "Loginaction" >
<result name= "Frame" >/frame.jsp </result>
</action>
</package>
</struts>
However, the following 500 errors are reported after submitting the form, if the direct write class= "com.system.actionLoginAction" can be executed

Unable to instantiate Action, loginaction, defined for ' login ' namespace '/' Loginaction

From the wrong view, Spring failed to create an action for struts2, which could be the cause:

1. Struts2-spring-plugin-2.1.8.1.jar not loaded

2. Package conflict, delete Asm.jar (online speaking)

3.struts or spring config file error (see my "struts2+spring Integration Framework")

4.spring configuration file name error, Spring profile default is Applicationcontext.xml, in Web. XML may be paired with

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/web-inf/applicationcontext-*.xml, classpath*:applicationcontext-*.xml< /param-value>
</context-param>
