错误如下：

我用到的开发框架和工具是：Myeclipse7.0 + tomcat5.5 + hibernate3.2 + spring2.5 + struts2.0，数据库是SQL Server2000，安装补丁包SP4。

Answer 1

还是把错误代码用google一下吧

目录有中文字符？

你的加载的包有误！

Answer 5

我导入的关于struts的包有以下几个：
commons-logging-1.0.4.jar
freeer-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.11.2.jar
struts2-spring-plugin-2.0.11.2.jar
xwork-2.0.5.jar这几个包有问题吗？

Answer 6

简单的，留下
(xwork-2.0.5.jar、
commons-logging-1.0.4.jar、
freeer-2.3.8.jar、
ognl-2.6.11.jar、
struts2-core-2.0.11.2jar)就可以运行了.Tomcat安装路径最好不要有中文和空格,用'_'代替空格吧..

Answer 7

struts2-spring-plugin-2.0.11.2.jar去掉，不懂别乱加，这个是和Spring配合时才能用，否则必死。因为struts2的基础webwork2中的Ioc容器本身就实现了。

Answer 8

http://zhanjianhua.javaeye.com/blog/644731试试这个,这个上面说清空所以缓存,再部署,你删掉webapps里面你的项目再试试...

Answer 9

Unable to load bean: type: class:com.opensymphony.xwork2.ObjectFactory - bean - jar:file:/F:/Tomcat%205.5/webapps/tjsm/WEB-INF/lib/struts2-core-2.0.11.2.jar!/struts-default.xml:30:72删掉一个应该就行了

Answer 10

我也用spring了，所以才需要那个包的

Answer 11

我试着把struts2-spring-plugin-2.0.11.2.jar去掉还是同样的错误提示。
tomcat安装路径是F:\Tomcat 5.5

Answer 12

我重现下载了struts2.0.14的包，导入后还是同样的问题。包如下：
commons-logging-1.0.4.jar
freeer-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.14.jar
struts2-spring-plugin-2.0.14.jar
xwork-2.0.7.jar

Answer 13

楼主在使用Spring 2.5嘛，为什么不加呢？有如下建议：
需要struts-spring插件，但是插件加入后，不用再在struts的配置文件配置Spirng的ObjectFactory，因为Struts 2采用了如同Eclipse的插件加载机制，所以只要将spring插件加入后，Struts 2便可以自动发现。建议看一下struts2-spring插件中包含的内容。

Answer 14

楼上的，你的意思是struts2会自动配置和spring的连接，我的struts-default.xml中不需要在配置ObjectFactory了是吗？

Answer 15

按照16楼的说法，我注释掉错误的地方，再启动时报错如下：
The package name 'struts-default' at location package - jar:file:/F:/Tomcat/webapps/tjsm/WEB-INF/lib/struts2-core-2.0.14.jar!/struts-default.xml:74:52 is already been used by another package at location package - file:/F:/Tomcat/webapps/tjsm/WEB-INF/classes/struts-default.xml:119:49 - package - jar:file:/F:/Tomcat/webapps/tjsm/WEB-INF/lib/struts2-core-2.0.14.jar!/struts-default.xml:74:52
这个怎么解决呀？

Answer 16

struts2-core-2.0.14这包中就有struts-default.xml了 你的配置文件中有 叫struts-default.xml的吧？重名了！！！！！
