Struts2.1.6 + hibernate3.2 开发部署_问题

1，项目由A机器迁移到另外一台B机器，jsp可以显示运行，但是Action找不到execute()方法，抛下列异常：

     java.lang.reflect.InvocationTargetException

     1）背景：

     A机器环境是MyEclipse7.1+JDK1.6.13+Tomcat6.0，B机器环境是MyEclipse7.0+JDK1.6.13+Tomcat6.0

     除了MyEclipse版本不同，其他包括项目目录都相同，项目使用SVN管理，绿色的文件图标一目了然地可以看到什么文件被修改了。

     2）操作：

     机器上的Tomcat 6.0\conf\Catalina\localhost\gaosir.xml配置容器。

     Myeclipse，JDK，tomcat6.0，均配置好后，启动MyEclipse里的tomcat服务。

     Login.jsp页面，正常显示页面，登陆用户名密码，提示500错误，

     抛出java.lang.reflect.InvocationTargetException异常。

     一般500错误，一般可以认为500错误是缺少资源，于是尝试了把所有的包手动导入一遍，无效。

     SVN可以看出文件目录的变化，没有发现任何异常。

     于是思考，工程里的文件不缺，配置都和A机器一样，不同处到底在哪里？目标很确定，就是找出不同处。

     在回头想想在B机器操作过程，A机器应用过程，细心之处见功夫了。

     在B机器，虽然配置了容器，jsp可以运行，但是没有应用部署。

     于是删除Tomcat 6.0\conf\Catalina\localhost\gaosir.xml文件，使用MyEclipse的deploy，重启，成功登陆。

     至此，问题解决。

     3）问题：

     继续调查，MyEclipse的deploy应用，以及手动配置容器，加载的不同之处。

     希望看到这篇文章的读者，能够给小生一个满意的答案。先谢过！

 

2，MyEclipse 应用tomcat，struts2.1.6 + hibernate3.2

     开发过程中新启动Tomcat一切正常。

     但是如果重新deploy，发现报严重错误如下：

    

    严重: Exception starting filter Struts2 
    Caught exception while loading file struts-default.xml - [unknown location]

    。。。

    但是把tomcat关掉，再deploy，再新启动，就一切正常。

    这个问题导致每做修改都要重启，简直崩溃啊！

    网上解决办法：去掉Hibernate core下面的xerces.jar包，彻底从lib里删除。

    删除tomcat下的webapp，和work下的webapp，再新启动tomcat，deploy，搞定。

   

    后序）hibernate中xerces.jar包作用：

 

    xalan.jar, xerces.jar, xml-apis.jar:

    Xerces是XML解析器，Xalan是格式化器，xml-apis实际上是JAXP。一般App Server都会带上，JDK1.4也包含了解析器，不过不是Xerces，是Crimson，效率比较差，不过Hibernate用XML只不过是读取配置文件，性能没什么紧要的，所以也是多余的。

 

3, 输入用户名密码登录后，页面提示错误如下：

4, Struts2 中 的表单实体对象为NUll

     究其原因，是因为表单对象里包含大写字母，mRy，在Action里也是mRy，竟然通不过，只有改成mry，重启，通过。
