[置顶] 将项目从tomcat 迁移到JBoss

注：针对的是jboss5.0,其它版本没有测试过 ，主要参考了：http://www.diybl.com/course/3_program/java/javajs/20100719/460908.html，在些表示感谢

将项目从tomcat 迁移到JBoss，一般情况下会出现很多问题，下面是相关问题的记录及解决方法。
1. (1)首先要新增两个jar包：jboss-as-sprint-int-5.0.0.GA.jar 和 jboss-spring-int-vfs.jar
（2）然后在web.xml 文件中加上以下配置
  <context-param>
          <param-name>contextClass</param-name>
          <param-value>
              org.jboss.spring.vfs.context.VFSXmlWebApplicationContext
          </param-value>
   </context-param>

2. 在web.xml 文件中，如果spring 相关文件是按以下方式配置的：
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext*.xml
  </param-value>
 </context-param>
 则要改为如下形式：
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
   classpath:applicationContext.xml,
   classpath:applicationContext-compass.xml,
   classpath:applicationContext-security.xml
  </param-value>
 </context-param>

3. 如果在其它的spring 配置文件（如applicationContext.xml等文件）中引用了xml 文件，如下
 <import resource="quartz.xml"/> 
 则要将改为如下引入方式：
 
 <import resource="classpath:quartz.xml"/>

4.启动时如果报类似如下错误，则将jboss common/lib 中 hibernate-validator.jar 删掉
Caused by: org.hibernate.AnnotationException: java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator.<init>(java.lang.Class, java.util.ResourceBundle, org.hibernate.validator.MessageInterpolator, java.util.Map, org.hibernate.annotations.common.reflection.ReflectionManager)

 at java.lang.Class.getDeclaredConstructor(Class.java:1985)
 at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:343)
 ... 149 more
5.经过上4个步骤后，启动一般不会报错了，但在访问程序时，可能会报类似以下错误：

 （注，根据你具体访问的url，报的错可能不是com.opensymphony.xwork2.ActionSupport.login() 方法以，而是其它方法）

这个错误解决方法如下 （这样解决只是权宜之计，如果哪位有更好的解决办法，请告之下）：
在classpath 路径下增加一个struts-plugin.xml 文件，内容如下 ：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

另注：以上过程都是通过在myEclipse中部署到jboss中的，接下来如果将程序导出为war包直接放到jboss下，启动时会报错，此时应该将war解压，将解压后的目录名后面加上.war，（如etshop.war包，解压后目录为etshop,将目录重命名为etshop.war）然后启动就不会报错了。
