public class ServerFileBrowser
extends DialogBox

Lets GWT applications browse and selects files that are present in the web server hosting the GWT application. For system administration purposes, very often, users have to specify a file or a directory in the server. This widget lets the user browser the files in the server using a file selector user interface.

Note that this component requires a GWT servlet to be running on the server. You will need to include the gwtcomp-servlet.jar in the WEB-INF/web.xml file and in the web.xml file, add the following segment:

   <servlet>
        <servlet-name>DirListingService</servlet-name>
        <servlet-class>
            org.cafesip.gwtcomp.server.DirListingServiceImpl
        </servlet-class>
    </servlet>
    ...
    <servlet-mapping>
        <servlet-name>DirListingService</servlet-name>
        <url-pattern>/gwtcomp/directoryService</url-pattern>
    </servlet-mapping>
 

CSS Style Rules:

• .gwtcomp-ServerFileBrowser { } - style for the file browser diaglog box
• .gwtcomp-ServerFileBrowserList { } - style for the file list
• .gwtcomp-ServerFileBrowserServerWait { } - style to be applied while the file browser is waiting to hear back from the server
