今天遇到Struts2与FCKeditor整合的问题，我很是无奈，上传图片有问题。还好网上有非常多的解决方案。
我的解决方案和那些差不多，struts2的filter把所有的请求都由org.apache.struts2.dispatcher.FilterDispatcher
转发了，fck的servlet也没有幸免，所以无法上传。可能会出现java.lang.NullPointerException
at com.fredck.FCKeditor.uploader.SimpleUploaderServlet.doPost(SimpleUploaderServlet.java:142)等诸多问题
我现在做个总结，集百家之所长，给出完美解决：
还是改web.xml
代码如下：
- < web-app version ="2.5" xmlns ="http://java.sun.com/xml/ns/javaee" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation ="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" >

还有个上传注意事项，上传的图片必须是英文名，不能是中文。
