去年在美期间在外导的项目中，需要用到el-finder的完美界面，但苦于没有java后端，因此做了一个elfinder-2.x-servlet。

附上项目说明，以后有空了附上中文版的：）

elfinder-2.x-servlet

elfinder-2.x-servlet implements a java servlet for elfinder-2.x connector

elfinder is an Open-source file manager for web, written in JavaScript using jQuery and jQuery UI. see also http://elfinder.org

for elfinder-1.2 users, please go to https://github.com/Studio-42/elfinder-servlet.

in the zip file you downloaded:

• WebRoot: a normal j2ee application includes elfinder, WEB-INF, jars ...
• src: source codes for elfinder-servlet

just use following codes to tell elfinder to connect with server-side servlet:

    <script type="text/javascript" charset="utf-8">
        $(document).ready(function() {
            $('#elfinder').elfinder({
                url : 'elfinder-servlet/connector',
            });
        });
    </script>

in your web.xml, following codes should be added to enable the servlet:

<servlet>
    <servlet-name>elfinder</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>elfinder</servlet-name>
    <url-pattern>/elfinder-servlet/*</url-pattern>
</servlet-mapping>

yes! elfinder-2.x-servlet is developed upon SpringFramework (http://springframework.org)

a sample elfinder-servlet.xml configuration is shown below:

<!-- find appropriate  command executor for given command-->
<bean id="commandExecutorFactory"
    class="cn.bluejoe.elfinder.controller.executor.DefaultCommandExecutorFactory">
    <property name="classNamePattern"
        value="cn.bluejoe.elfinder.controller.executors.%sCommandExecutor" />
    <property name="map">
        <map>
        <!--
            <entry key="tree">
                <bean class="cn.bluejoe.elfinder.controller.executors.TreeCommandExecutor" />
            </entry>
        -->
        </map>
    </property>
</bean>

<!-- FsService is often retrieved from HttpRequest -->
<!-- while a static FsService is defined here -->
<bean id="fsServiceFactory" class="cn.bluejoe.elfinder.impl.StaticFsServiceFactory">
    <property name="fsService">
