struts2上的fckeditor插件

struts2下的fckeditor插件
1、不需要fckEditor原文件
2、支持注入UserAction
3、上传文件自动改名和排序
4、支持fckEditor根目录不在WEB应用内
5、fckEditor的filter不需要了
6、自动对大的图片文件进行裁减
6、修改/fckeditor.properties可以适应struts.action.extension的变化

jar和war都做了更新
fckeditor.image.max.size = 1024fckeditor.image.max.width = 450fckeditor.image.max.height = 450
4、struts扩展名不是action的情况；

fckeditor.struts.extension = do

5、在jsp中:

<%@ taglib uri="http://java.fckeditor.net" prefix="FCK" %><FCK:editor instanceName="EditorDefault"/>

<constant name="struts.multipart.maxSize" value="20971520" />
fckeditor.image.max.size是用来判断大图片文件的
超过这个尺寸的图片文件需要做缩略图
2、缩略图的代码对jpg是支持的
引用很希望您能做个比较详细的例子（关于图片上传的）
3、例子可以参看上传的fcktest.war


8 楼 dengquangang 2009-06-23   如果我想移除fckEditor里面的某项功能，不想要上传图片，不想要上传flash等，该怎么解决呀，谢谢啦 9 楼 wanghui_chris 2009-11-13   有个问题请教，如果我想把上传目录不放到web应用下，该如何做呢？
我在fckeditor.properties中增加了下面一行：
connector.userFilesPath = c:\tmp，但查看服务器时系统告诉我是个无效目录。
希望楼主帮我解决一下这个问题。我的测试环境就是楼主提供的那个war.
