struts2相关问题

Question

我在web.xml里加以下filter后出现异常, 怎么解决?  jar包全加上了, struts.xml在classes里.
<filter>
        <filter-name>struts2x</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>    <filter-mapping>
        <filter-name>struts2x</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
严重: Exception starting filter struts2x

Answer 1

你架包有问题，你去下最新架包用一下６个就没问题啦
ognl-2.6.11.jar
struts2-core-2.1.6.jar
xwork-2.1.2.jar
commons-fileupload-1.2.1.jar
commons-logging-1.0.4.jar
freeer-2.3.13.jar

Answer 2

Unable to load bean: type: class:com.opensymphony.xwork2.ObjectFactory
struts2默认使用spring的objectfactory.如果你把所有的jar都加上的话....它会以为你要使用webwork的objectfactory?commons-fileupload-1.2.1.jar 不是必须的吧.

Answer 3

有谁出现过和我一样的错误, 1楼,2楼的都试了还是同样的问题,我之前是只把struts2开头的都去掉,只留struts2-core-2.1.6.jar然后没出现错误. 现在那样也不行. 我把struts.xml放在classes里, 每次刷新lib它怎么自动消失啊? 我用的是struts2.1.6.
请教还有其他方法吗?
