先说怎么�?再稍微解释一下�ؓ(f��)什么这么做
1.webwork.properties里面讄��
webwork.serve.static=false
webwork.multipart.parser=cos
2.在webapp的根目录下徏一个文件夹webwork,把webwork.jar里面�?com/opensymphony/webwork/static�?template里面的文件和复制到自己徏的webwork文�g多w��?�?webwork/richtexteditor里面建文件夹data(可能�?x��)自动�?没测试过)
3.写一个RichtexteditorConnector

package test;

import java.io.FileFilter;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.ServletContext;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.opensymphony.webwork.components.DefaultRichtexteditorConnector;

public class RichtexteditorConnector extends DefaultRichtexteditorConnector {
    public static final Log _log = LogFactory
            .getLog(RichtexteditorConnector.class);

    private ServletContext servletContext;

    public void setServletContext(ServletContext servletContext) {
        this.servletContext = servletContext;
    }

    protected String calculateActualServerPath(String actualServerPath,
            String type, String folderPath) throws Exception {
        String path = servletContext.getRealPath(actualServerPath);
        path = path.replace('\\', '/');
        makeDirIfNotExists(path);
        path = path.endsWith("/") ? path : path + "/";
        return path + type + folderPath;
    }

    protected Folder[] getFolders(String virtualFolderPath, String type)
            throws Exception {
        String path = calculateActualServerPath(getActualServerPath(), type,
                virtualFolderPath);
        makeDirIfNotExists(path);
        java.io.File f = new java.io.File(path);
        java.io.File[] children = f.listFiles(new FileFilter() {
            public boolean accept(java.io.File pathname) {
                if (!pathname.isFile()) {
                    return true;
                }
                return false;
            }
        });

        List tmpFolders = new ArrayList();
        for (int a = 0; a < children.length; a++) {
            tmpFolders.add(new Folder(children[a].getName()));
        }

        return (Folder[]) tmpFolders.toArray(new Folder[0]);
    }

    protected FoldersAndFiles getFoldersAndFiles(String virtualFolderPath,
            String type) throws Exception {
        String path = calculateActualServerPath(getActualServerPath(), type,
                virtualFolderPath);
        makeDirIfNotExists(path);
        java.io.File f = new java.io.File(path);
        java.io.File[] children = f.listFiles();

        List directories = new ArrayList();
        List files = new ArrayList();
        for (int a = 0; a < children.length; a++) {
            if (children[a].isDirectory()) {
                directories.add(new Folder(children[a].getName()));
            } else {
                try {
                    files.add(new File(children[a].getName(),
                            fileSizeInKBytes(children[a])));
                } catch (Exception e) {
                    _log.error("cannot deal with file " + children[a], e);
                }
            }
        }

        return new FoldersAndFiles((Folder[]) directories
                .toArray(new Folder[0]), (File[]) files.toArray(new File[0]));
    }

    protected FileUploadResult fileUpload(String virtualFolderPath,
            String type, String filename, String contentType,
            java.io.File newFile) {
        try {
            String tmpDir = calculateActualServerPath(getActualServerPath(),
                    type, virtualFolderPath);
            makeDirIfNotExists(tmpDir);
            String tmpFile = tmpDir + filename;
            if (makeFileIfNotExists(tmpFile)) {
                // already exists
                int a = 0;
                String ext = String.valueOf(a);
                tmpFile = calculateActualServerPath(getActualServerPath(),
                        type, virtualFolderPath)
                        + filename + ext;
                while (makeFileIfNotExists(tmpFile)) {
                    a = a + 1;
                    ext = String.valueOf(a);
                    if (a > 100) {
                        return FileUploadResult.invalidFile();
                    }
                }
                copyFile(newFile, new java.io.File(tmpFile));
                return FileUploadResult
                        .uploadCompleteWithFilenamChanged(filename + ext);
            } else {
                copyFile(newFile, new java.io.File(tmpFile));
                return FileUploadResult.uploadComplete();
            }
        } catch (Exception e) {
            _log.error(e.toString(), e);
            e.printStackTrace();
            return FileUploadResult.invalidFile();
        }
    }

    protected void unknownCommand(String command, String virtualFolderPath,
            String type, String filename, String contentType,
            java.io.File newFile) {
        throw new RuntimeException("unknown command " + command);
    }

    /**
     *
     * @param path
     * @return true if file already exists, false otherwise.
     */
    protected boolean makeDirIfNotExists(String path) {
        java.io.File dir = new java.io.File(path);
        if (!dir.exists()) {
            _log.debug("make directory " + dir);
            boolean ok = dir.mkdirs();
            if (!ok) {
                throw new RuntimeException("cannot make directory " + dir);
            }
            return false;
        }
        return true;
    }

    protected boolean makeFileIfNotExists(String filePath) throws IOException {
        java.io.File f = new java.io.File(filePath);
        if (!f.exists()) {
            _log.debug("creating file " + filePath);
            boolean ok = f.createNewFile();
            if (!ok) {
                throw new RuntimeException("cannot create file " + filePath);
            }
            return false;
        }
        return true;
    }

}

4.xwork.xml加上

<package name="richtexteditor-browse" extends="webwork-default"
        namespace="/webwork/richtexteditor/editor/filemanager/browser/default/connectors/jsp">
        <action name="connector"
            class="test.RichtexteditorConnector"
            method="browse">
            <param name="actualServerPath">
                /webwork/richtexteditor/data
            param>
            <result name="getFolders" type="richtexteditorGetFolders" />
            <result name="getFoldersAndFiles"
                type="richtexteditorGetFoldersAndFiles" />
            <result name="createFolder"
                type="richtexteditorCreateFolder" />
            <result name="fileUpload" type="richtexteditorFileUpload" />
        action>
package>
<package name="richtexteditor-upload" extends="webwork-default"
        namespace="/webwork/richtexteditor/editor/filemanager/upload">
        <action name="uploader"
            class="test.RichtexteditorConnector"
            method="upload">
            <param name="actualServerPath">
                /webwork/richtexteditor/data
            param>
            <result name="richtexteditorFileUpload" />
        action>
package>

5.配置标签

   <%request.setAttribute("contextPath",request.getContextPath());%>

6.服务器端口设�|��ؓ(f��)80

原因
1.
webwork.serve.static=false
/webwork/*�q�样的URL是可以直接访问不需要通过webwork,�q�样做是��Z��自己可以在里面徏文�g,�q�且可以方便的访问这些文�?br />webwork.multipart.parser=cos
讄��为jakarta上传文�g不成�?com.opensymphony.webwork.interceptor.FileUploadInterceptor解析MultiPartRequestWrapper不成�?原因不清�?反正用cos��可以了,记得加上cos.jar
2.因�ؓ(f��)讄��了webwork.serve.static=false需要这样做
3.覆盖webwork的DefaultRichtexteditorConnector,最关键的是覆盖calculateActualServerPath()�Ҏ(gu��)��,默认是把文�g攑ֈ�/WEB-INF/classes/com/opensymphony/webwork/static/richtexteditor/data/,我们需要放�?webwork/richtexteditor/data/里面,覆盖其他�Ҏ(gu��)��是因为默认对文�g的访问都是通过
new File(new URI("file://"+filePath);来访问的,�?x��)有些问�?直接new File(filePath)��可以了
4.使用自己的RichtexteditorConnector,�q�且讄��参数actualServerPath,其他参数不要�?webwork默认的是�q�样
5.basePath必须自己指定不能用默认的,虽然指定的值和默认的是一�?但是不自己指定的话它自动加上jsessionid,�?webwork/richtexteditor/;jsessionid=301gs94034pki/editor/fckeditor.html,因�ؓ(f��)讄��了webwork.serve.static=false,所以服务器不能解析�q�个url
defaultLanguage="zh-cn",不指定的话中文默认是�J�体
6.服务器端口必��Mؓ(f��)80不能�?080,因�ؓ(f��)fckeditor链接你上传的文�g的时�?不会(x��)把端口加上去

webwork2.2.2内置了fckeditor�Q�用�?br />

<ww:richtexteditor toolbarCanCollapse="false" width="700" label="描述" name="description"/>

xwork.xml加入�Q?br />

<package name="richtexteditor-browse" extends="webwork-default"
        namespace="/webwork/richtexteditor/editor/filemanager/browser/default/connectors/jsp">
        <action name="connector"
            class="com.opensymphony.webwork.components.DefaultRichtexteditorConnector"
            method="browse">
            <result name="getFolders" type="richtexteditorGetFolders" />
            <result name="getFoldersAndFiles"
                type="richtexteditorGetFoldersAndFiles" />
            <result name="createFolder" type="richtexteditorCreateFolder" />
            <result name="fileUpload" type="richtexteditorFileUpload" />
        action>
package>
<package name="richtexteditor-upload" extends="webwork-default"
        namespace="/webwork/richtexteditor/editor/filemanager/upload">
        <action name="uploader"
            class="com.opensymphony.webwork.components.DefaultRichtexteditorConnector"
            method="upload">
            <result name="richtexteditorFileUpload" />
        action>
package>

存在如下问题:

1.中文环境默认是繁�?需要去包里面用zh-cn.js替换zh.js
2.String path = "file://"+servletContext.getRealPath("/WEB-INF/classes"+actualServerPath),windows文�g路径是\,webwork没有转义或者把\替换�?,�Ҏ(gu��)��件的讉K��都是通过new File(new URI(filePath))来访�?在我机子上会(x��)��Z��?br />com.opensymphony.webwork.dispatcher.DispatcherUtils - Could not execute action
java.lang.IllegalArgumentException: URI has an authority component
at java.io.File.(File.java:326)
at com.opensymphony.webwork.components.DefaultRichtexteditorConnector.makeDirIfNotExists(DefaultRichtexteditorConnector.java:171)

解决�Ҏ(gu��)��是自己写一个类�l�承com.opensymphony.webwork.components.DefaultRichtexteditorConnector然后覆盖它的�Ҏ(gu��)��

3.文�g囄��默认是保存在\WEB-INF\classes\com\opensymphony\webwork\static\richtexteditor\data里面,写入和读取都存在问题,写入的时候如果context是reloadable="true"则会(x��)引发context的reload,在context��h��之后新加的文件比如test.jpg不能通过url来访�?webwork/data/test.jpg,�q�个应该是classloader不会(x��)在context启动之后加蝲�q�些文�g

4.上传的表单里面没有action,虽然tag里面默认�?br />imageUploadURL="/webwork/richtexteditor/editor/filemanager/upload/uploader.action?Type=Image"
flashUploadURL="/webwork/richtexteditor/editor/filemanager/upload/uploader.action?Type=Flash"
linkUploadURL="/webwork/richtexteditor/editor/filemanager/upload/uploader.action?Type=File"
wikidocs里面说是"/webwork/static/richtexteditor/editor/filemanager/upload/uploader.action?Type=File"应该是多了个/static
但是实际上上传的form里面的action是空�?上传不了东西,�q�个可能需要去改fckeditor
