List files/directories in JSP page

Hi. How can i list all files in a specified folder? I need to list all files from some directory and create a select element with retrived filenames. What class i need to use?.
Thanks.

File directory = new File(url);
     if(directory.isDirectory()) {
          File[] files = directory.listFiles();
        }Then, in your JSP page, you take the file list (with a JavaBean for example) and with a for loop you create a SELECT BOX.
<%
    for(int i=0; i<filelist.size(); i++) {
%>
        <OPTION>filelist.get(i).getName()</OPTION>
<%
%>

    JSPs are compiled into servlets automatically and those classes are stored in WEB-INF/classes folder. Servlet engine handles servlets.

  • How to include a .class file in a jsp page

    hi everyone,
    i know the syntax as:

    if i use,
    <%@ page import = "FileName.class" %>
    then also the same problem persists
    & if i use

    please help me out...i am working on developing an EJB application in which client interacts with server's Stateful session bean through a jsp page...it is necessary for me to include the home interface class file in my jsp page.

    "package University does not exist".How can i overcome this problem. The package University, which you are trying to import, must be in the classpath. If you removed it then you will have to add it back.
    i have tried my best..but tell me if there's any possible way of including a class file in the jsp page without involving a package.No, there isn't.
    If not,then pls help me to generate the class file of my home interface within a package called test.Read the New To Java Tutorial and understand how packages work.

  • Uploading a file in a jsp page

    Hii Javaites
    I am developing an application in which i need to upload file from a jsp page, right now i am using tomcat can anyone tell me the code for uploading a file.
    Thanking in Advance

    Hi,
    For uploading file from jsp:
    1) Goto javazoom.com, then download latest version for upload the files.
    2) Extract the zip & thay giving four jar files
    they are:
    i)uploadbean.jar
    ii)struts.jar
    iii)fileupload.jar
    iv)cos.jar
    put all this jar in lib of u r web application
    ex:
    C:\jakarta-tomcat-5.0.25\webapps\URWEBAPP\WEB-INF\lib\
    3) Set it in class path
    4) create one jsp with file option<input type='file' name = 'somename'>
    5) In action page(next page)
    <%@ page language="java" import="javazoom.upload.*,java.util.*" %>
    <%@ page errorPage="error.jsp" %>
    <jsp:useBean id="upBean" scope="page" class="javazoom.upload.UploadBean" >
    <jsp:setProperty name="upBean" property="folderstore" value="c:/uploads" />
    </jsp:useBean>
    Set the folder where u want upload the particular file.
    MultipartFormDataRequest mrequest = new MultipartFormDataRequest(request);
    Hashtable files = mrequest.getFiles();
         UploadFile file = (UploadFile) files.get("somename");//Give name u r given in the previous page.
         String fileName = file.getFileName();     
    upBean.store(mrequest, "userFile");
    follow this steps it works fine.

  • I used tag to show PDF file inside my JSP page, It is working properly in IE but nothing shows in Mozilla. What should I do?

    I've used to display a PDF file inside my JSP page. It is working fine in IE. However, many of users of this application are using Mozilla and the platform is Ubuntu so it is vital that the file is shown in Mozilla as well. How can I solve this problem.
    == This happened ==
    Every time Firefox opened
    == I run my jsp page

    Such conditional code will only work in IE and not in other browsers like Firefox.

  • Write an image file to a jsp page

    Hy,
    I've writen a small program, which draws a chart. The program normally creates a .png file of this chart which it stores on the file system and then read the png file and display the chart on a jsp page. Now, what I want is that, instead of writing the png file on the filesystem, i write it on a jsp page and then read the file from that jsp page. (i.e Its the jsp page which contains the image file).
    Can anyone please explain to me how to achieve this and if possible the codes also
    thanks in advance

    Hi, gulshan21
    JSP pages are intended to send text type content (though in the most of the containers this approach seems works fine). The best thing is to make a servlet, like this:
    import javax.servlet.*;
    import javax.servlet.http.*;
    import java.io.*;
    import java.awt.*;
    import javax.imageio.*;
    import java.awt.image.*;
    public class GraphicServlet extends HttpServlet {
      public void doGet(HttpServletRequest request,
                                       HttpServletResponse response)
                               throws ServletException, IOException {
        response.setContentType("image/jpeg");     // Or "image/png"
        OutputStream os = response.getOutputStream();
        ImageIO.write(getImage(100, 100), "PNG", os);      // Sends the image
        os.close();
      private synchronized BufferedImage getImage(int width, int height) {
        BufferedImage img = new BufferedImage(width, height,
                                                                                    BufferedImage.TYPE_INT_RGB);
        Graphics g = img.createGraphics();
        // Here you draw the image with the graphics methods
        g.dispose();
        return img;
    }Salud

    Any kind of help will be highly appreciated.
    Pinkesh

    Hi Adam Winer,
    I want to try your solution.
    just wanted some more clarification .....
    So, let's say you have:
    DWStaticJSP.jsp: plain JSP
    report_palm.jsp: JSF JSP included by DWStaticJSP.jsp
    What you should do is use an URL of:
    /faces/DWStatic.jsp
    to access the outer plain JSP (yes, even though it's not really a faces page), and then have
    /faces/DWStatic.jsp include just plain /report_palm.jsp.
    In essence, the critical thing is that the FacesServlet wraps the entire request - FacesServlet cannot run
    for just a piece of the request.My question is where should i store the DWStatic.jsp file ... As u said i should acces it using /faces/DWStatic.jsp do i need to save it in the faces folder or just in the web app root.
    I cant save the DWStatic.jsp in the faces folder as this file is used for lot of different purpose in my company application.
    So can u give me a solution where in i can keep the DWStatic.jsp in the web-root folder and still try your solution
    Also is this the right setting for facesServlet in the web.xml.
    <servlet>
    <servlet-name>FacesServlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- Faces Servlet Mapping -->
    <servlet-mapping>
    <servlet-name>FacesServlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    Whatever follows below this line is the describtion of the web appp structure which i have in my company.
    We have an application where in all the jsp files are stored in the web-app root folder.....
    I will be using alphabets like a.jsp ... b.jsp .... to keep the explanation small...
    I have an a.jsp file which includes a b.jsp file which in turn includes a c.jsp......
    Now we have started using JSF.....
    Now as a developer .... i want the c.jsp to include a d.jsp file which contains JSF components...
    The thing is i cant change the location of a.jsp, b.jsp and c.jsp......
    Can u tell me how i should call " a.jsp" ... imean the url so that the "d.jsp" file gets processed properly.
    Also where should i save all the jsp files and what config is requiered in the web.xml for your solution
    I thank you for your help

    Did you try Object-> insert HTML, see if that helps

  • File Chooser into JSP pages

    Hello, i would like to allow the user of one of my JSP page to choose a file on his computer, as doing attachment. Is it possible?? Do you see some better way to do that??
    Thanks

    Yes, it's possible. But you can't use a FileChooser, that's a Java class. You need an HTML solution, and there is one. You use a form with enctype="multipart/form-data" and an input box with type="file". Do you use Internet e-mail like Hotmail? If you do, then look at the HTML they use when you send a mail with attachments.
