这个问题是在使用Struts2想做一个上传文件的页面时候Tomcat报出来的错误,详细信息如下:
2007-7-19 21:34:09 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet jsp threw exception

最后Google了不少文章,找到了原因:(缺少了必要的jar包)

Struts2使用开源项目Apache Jakarta Commons FileUpload和内建的FileUploadInterceptor拦截器实现文件上传,所需的jar包如下:

commons-logging-1.1.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.6.jar
xwork-2.0.1.jar
commons-io-1.3.1.jar
commons-fileupload-1.2.jar

我也出现了这样的问题,不过我那jar包添加进去了的
不过改web.xml,把原来的
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
改为
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
就行了  回复  更多评论
