HelloWorld:

引入：

<script type="text/javascript" charset="utf-8" src="../ueditor/editor_all.js"></script>
<script type="text/javascript" charset="utf-8" src="../ueditor/editor_config.js"></script>

配置：

//配置Ueditor的地址
var URL = window.UEDITOR_HOME_URL||"/company/ueditor/";

JS：

//name="content"  后台获取数据的名字即 request.getParameter("content");
<textarea id="myEditor" name="content" cols="80" rows="20" class="textarea">可以写入初始化内容</textarea>
      <script type="text/javascript">
      UE.getEditor('myEditor',{
            initialFrameWidth:1000
            ,initialFrameHeight:350
            ,initialContent:""
            ,charset:"gb2312"
            //工具栏上的所有的功能按钮和下拉框，可以在new编辑器的实例时选择自己需要的从新定义
            ,toolbars:[["fullscreen","source","undo","redo","insertunorderedlist","insertorderedlist","unlink","link","cleardoc","selectall","print","searchreplace","preview","help","pagebreak","insertimage","music","snapscreen","emotion","insertvideo","attachment","insertframe","date","time","horizontal","blockquote","highlightcode","template","background","bold","italic","underline","strikethrough","forecolor","backcolor","superscript","subscript","justifyleft","justifycenter","justifyright","justifyjustify","indent","removeformat","formatmatch","pasteplain","customstyle","imagecenter","imageright","imageleft","imagenone","fontsize","fontfamily","lineheight","rowspacingtop","rowspacingbottom","paragraph","inserttable","deletetable","mergeright","mergedown","splittorows","splittocols","splittocells","mergecells","insertcol","insertrow","deletecol","deleterow","insertparagraphbeforetable"],[],[]]
           });
      </script>

据此helloworld就配好了。

图片上传：

配置上传地址(采用默认地址也可上传，但是在ueditor/jsp/ 文件夹下)：

//和生成图片链接有关
,imagePath: "/company/uploadImages/"

配置JSP地址：

//和保存文件有关，由于处理的JSP文件和实际图片上传的文件夹不是同级别关系，因此配置路径比较麻烦，不过多测试几次就可以
request.setCharacterEncoding("gbk");
response.setCharacterEncoding("gbk");
Uploader up = new Uploader(request);
up.setSavePath(../../uploadImages/);
...

//这里返回的地址使用up.getUrl(); 通常也是有问题的，需要处理后才能生成正确的链接地址。
response.getWriter().print("{'original':'"+up.getOriginalName()+"','url':'"+up.getUrl()+"','title':'"+up.getTitle()+"','state':'"+up.getState()+"'}");
