Creating a File object in a JSP page

Hi,
I am trying to create a File object in my JSP page by passing it a relative path. The jsp page is in 'website/testfolder/index.jsp' and the File is in 'website/photos/1.jpg'. In my jsp page i do the following:
<% File f = new File("../photos/1.jpg");
boolean test = f.isFile(); %>
The value returned is false. I am trying to figure out why it can't locate the file.
Thanks

You have to use absolute paths. You can get the absolute path for the given relative path by ServletContext#getRealPath().

Using Java Objects in my JSP page... objects are in a different directory

Hi,
I would like to call and use an object from a JSP page. The java object is in one directory, the jsp is in another. When I call my object, I get a JSP error that says it can't find the object and lists the directory name as part of the file.
For example, here are my two files:
/java/MyObject.class
/web/page.jsp
When I make the call to new MyObject(), I get an error message saying _web.MyObject cannot be found. Any ideas on this?
Thanks!

Okay, I figured it out. In case anyone else needs it, here is what I needed to do.
1) I created my object in a package. The JSP page was looking for the object in _dir directory because a package wasn't specified. I created a subdirectory in one of the directories in my classpath and named it the same thing that the package was named.
2) Import the package
3) Make sure all methods in the classes are public, since only public methods can be accessed from outside the package.
Thanks for the help, it got me going in the right direction.

How to display XML file(as markup) in jsp page..?

Hi All,
* I have to display the XML file(as markup) in jsp page (Tree Format)....
* My XML file is an java.io.file object , and how to view this XML file on my JSP page...........
Thanks in Advance,
JavaImran

You mean you want to see the XML source?
You need to replace the characters '<' and '&' with corresponding entities '<' and '&'. You can use replaceAll, but do the ampersands first.
Then I suggest you probably want to put them in a <PRE> block.

Retrieving an ArrayList object in a JSP page and loop it

i have these statements in the java servlet class:
request.setAttribute("searchresults",searchResults);
request.getRequestDispatcher("/searchStaff.jsp").forward(request, response);
return;the searchResults is the ArrayList object.
i would very much like to know how i can retrieve this object in a JSP page and iterate through this ArrayList using JSTL. I know i will need to use the <c:forEach> tag but i don't know what i should include in the body of this tag.
thanks a lot~~~~~

<c:forEach var="columnName" items="${requestScope.searchResults}">

Can I create a File object without writing it to the disk?

I need construct a mechanism where I can "write" instructions to a file and then FTP this file to a remote system. It is basically a Telnet-like integration for a system that does not support Telnet. Once the file is on the remote device, it knows how to read the file and process its instructions.
I would like to logically create this File object, by that I mean that I would like to use a FileWriter object to write the text instructions to the File, then use the Jakarta Commons NET API to FTP the file to the remote system. My question: can I create this File object without the file actually being written to the file system? Can the File just be memory resident for this creation and FTP?
There could be tens of thousands of these transactions per day and I would like to just avoid any kind of deletion strategy, if I can. Thanks.

Apart from the questionable decision to try and mess with the File object, I think the answer to (my guess at) your original question is "Yes".
Jakarta Commons/Net FTP can upload to a server from any input stream you like. It doesn't have to be a FileInputStream. In particular it could be a ByteArrayInputStream, which reads from a byte array in memory.

Importing Class Objects created in IFS Manager into a JSP page

I create a class object using IFS Manager which consisted of extended attributes. I hope this is the right thing to do when I want to manage some extra attributes of a DOCUMENT. But the question is what package do I import to access this newly create Class Object

Thank you. The information was very helpful.
<BLOCKQUOTE>quote:<HR>Originally posted by Joyce Peng:
I believe you created a subclass of Document using iFS manager.
Your new subclass is like any other class object in iFS.
Here is an example of how to access a custom class EXPENSEREPORT with a custom attribute APPROVER.
//Gets the the collection of all the class objects.
//Then gets the specific EXPENSEREPORT class object.
Collection classObjectCollection = session.getClassObjectCollection();
ClassObject expenseReportClassObject =
(ClassObject) classObjectCollection.getItems("EXPENSEREPORT");
//Gets the APPROVER attribute for the class object.
Attribute attribute = expenseReportClassObject.getEffectiveClassAttributes("APPROVER");

i am very glad and appreciate for your help, but i would like to know how to get the value of a radio button.
like in another JSP file i have :
<input type="radio" name="type" value="Return" checked>
Return

Creating a file download link on jsp

I have the following on my jsp. The code worked fine until I tried to use it in a new html design page.
<code>
//page name is index.jsp
try //DISPLAY THE CONTENTS OF THE DATA DIRECTORY
File dirname = new File(PATH); // create an instance of the File class
if (dirname.exists()&&dirname.isDirectory())//check to see if File class dirname exists and is valid
String [] allfiles = dirname.list();//create an array of files in the dirname File class
 for (int i=0; i< allfiles.length; i+=2)//loop through allfiles[] and print out file links
out.println(" <table border='1' cellspacing='1' width='99%'>");
 out.println("<tr><td width='50%' class='pageFont'><input type='checkbox' name='cb' value='"+allfiles[i]+"'>"+allfiles[i]+" ");
%>
<a class="a" href="index.jsp?downfile=C:\\data\\<%=allfiles[i+1]%>">DOWNLOAD</a></td>
<% if(i+1 < allfiles.length)//PRINTS OUT THE SECOND TD SO THAT WE HAVE 2 COLUMNS OF LINKS
out.println("<td width='50%' class='pageFont'><input type='checkbox' name='cb' value='"+allfiles[i+1]+"'>"+allfiles[i+1]+" ");
%>
<a class="a" href="index.jsp?downfile=C:\\data\\<%=allfiles[i+1]%>">DOWNLOAD</a></td></tr>
<%
out.println("</form></table>");
catch (IOException excep)
 out.println("An IO exception has occured.");
</code>
Then when clicked this code is run:
<code>
try{
//CHECK TO SEE IF THE FILE HAS BEEN CLICKED TO DOWNLOAD SINGLE FILE
if (request.getParameter("downfile") != null)
String filePath = request.getParameter("downfile");
File f = new File(filePath);//CREATE AN INSTANCE OF THE FILE CLASS AND POINT IT TO THE LOCATION OF THE DIRECTORY CONTAINING THE FILES
if (f.exists() && f.canRead())
response.setContentType ("application/octet-stream");
response.setHeader ("Content-Disposition", "attachment;filename=\""+f.getName()+"\"");
response.setContentLength((int) f.length());
BufferedInputStream fileInputStream = new BufferedInputStream(new FileInputStream(f));
int i;
out.clearBuffer();
while ((i = fileInputStream.read()) != -1) out.write(i);
fileInputStream.close();
out.flush();
</code>
When I click on this link I get the download dialog box. If I open it I get the following open up in notepad(the files I am trying to give download links are .txt files)
Below is what is displayed in notepad ALL on 1 line:
<html>
<head>
<LINK rel="stylesheet" ty
That is displayed in all of the links that I click on. It is the first few lines of html code for index.jsp.
I know this code is probably not a good way of doing what I need but I got it to work fine until the change.
I am sure there is an easier way to code the download link without resubmitting the page.
Thanks in advance!!

Well all was fine with this jsp until I moved it to ApacheJServ. Now the problem has resurfaced(although it is a little different now)
I had moved the following code to the top of my page:
//CHECK TO SEE IF EITHER DOWNFILE OR ZIPFILE VARIABLE EXIST, AND IF THEY DO SET CONTENT TYPE BEFORE SENDING ANY HTML CODE TO THE BROWSER
try{
//CHECK TO SEE IF THE FILE HAS BEEN CLICKED TO DOWNLOAD SINGLE FILE
 if (request.getParameter("downfile") != null)
 String filePath = request.getParameter("downfile");
 File f = new File(filePath);//CREATE AN INSTANCE OF THE FILE CLASS AND POINT IT TO THE LOCATION OF THE DIRECTORY CONTAINING THE FILES
 if (f.exists() && f.canRead())
 response.setContentType ("application/octet-stream");
 response.setHeader ("Content-Disposition", "attachment;filename=\""+f.getName()+"\"");
 response.setContentLength((int) f.length());
 BufferedInputStream fileInputStream = new BufferedInputStream(new FileInputStream(f));
 int i;
 out.clearBuffer();
 while ((i = fileInputStream.read()) != -1) out.write(i);
 fileInputStream.close();
 out.flush();
 response.flushBuffer();
catch (Exception e){}
//This is where the java code ends and the javascript/html code begins.Then further into the page I create the file download links like so:
 <a class="a" href="main.jsp?downfile=C:\\data\\<%=allfiles[i+1]%>">DOWNLOAD</a>I know this isnt a secure way of doing this but I am on a intranet.
The problem I am having now is that when I click on one of the links and download the file and then open it, I get the contents of the file plus concatenated to the end of it is the first few HTML lines of the actual jsp that I downloaded the file from. Before I was just getting the first few lines of html from the jsp, not the actual contents of the downloaded file.
This is an example of what I am getting:
This is the contents of the file that I downloaded.//This is where the file contents ends.
<html>
<head>
<LINK rel="stylesheet" type="text/css" href="default.css">
<script language="JavaScript1.2">
//function that allows user to select all checkboxes
function doIt(v)
for(var i=0;i<document.form1.cb.length;i++)
 document.form1.cb.checked=eval(v);
function swap(imageName,image)
imageName.src = "templateImages/"+image;
function imageOver(imageSrc, imageName)
 changeImage = new Image();
 changeImage.src = imageSrc;
 document.images[imageName].src = changeImage.src;
var hide = true;
function hideShow( ) /
Any morre ideas?
TIA!
BTW, I went to ApacheJServ because they wont let me use tomcat :(

Get the class file name of the JSP page

Hi
I'm wondering how I can get the class name associated with the current JSP page...
I found on this forum how get the name of current JSP page, but it doesn't help me...
Thanks

Hi,
Sometimes I can be really dumb; of course, the solution is to call the getClass() method on the this object, and eventually store the Class object returned in the SessionBean file if it's necessary (in a SessionBean field/property, or in a parameter of a SessionBean's method).
Sorry for this thread without any interest. :(

How to break up a huge XML file and generate serialized JSP pages

I have a huge xml file, with about 100 <item> nodes.
I want to process this xml file with pagination and generate jsp pages.
For example:
Display items from 0 to 9 on page 1 page1.jsp , 10 to 19 on page2.jsp, and so on...
Is it possible to generate JSP pages like this?
I have heard of Velocity but dont know if it will be the right technology for this kind of a job.

Thank you for your reply, I looked at the display tag library and it looks pretty neat with a lot of features, I could definitely use it in a different situation.
The xml file size is about 1.35 MB, and the size is unpredictable it could shrink or grow periodically depending on the number of items available.
I was hoping to create a documentation style (static pages) of the xml feed instead of having 1 jsp with dynamic pages
I was looking at Anakia : http://jakarta.apache.org/velocity/docs/anakia.html , may be it has features that enable me to create static pages but not very sure.
I think for now, I will transform the xml with an xsl file and pass the page numbers as input parameters to the xsl file

How to create a file object for a file on Remote Server? UNIX

Hi all,
I am working on two servers A and B. BOTH ARE UNIX MACHINES. My java class exist on server A and executes on same server. The file that I need to process resides on server B. (Lets call it test.txt in MYTEST directory. So path will be /MYTEST/test.txt on server B) I need to do few things before I can process it:
1) Check if file exist
2) If it does FTP it to Server A. (I already know how to.)
For both of these tasks, I need a File object for that file.
My problem is that I am unable to set it up.
\\B\MYTEST\test.txt will not work on UNIX. I already tried that. (It only works on Windows)
I tried:
/B/MYTEST/test.txt ---- Does not work
B:/MYTEST/test.txt ---- Does not work
:B/MYTEST/test.txt ---- Does not work
B:MYTEST/test.txt ---- Does not work
All of these instances say the same thing: "File does not exist."
Any ideas? Please help!!!

I by no means want to sound belittling... so don't take me that way..
You need to understand the basics of files, and networks. You can't check if a file exists on another machine if you don't have a network protocol to communicate with. The reason \\ works under windows is because you are using an invisible (to you) network protocol. You probably know it as windows sharing. If your file were not shared under it's own name, that method wouldn't work (I'm assuming your entire drive is shared without a password... a horrible security flaw...but one thing at a time)
You can use FTP protocol to check if a file exists. You can either send the raw text FTP commands through a socket connection in java, or you can use a freely available FTP java API to make it a bit more simple. You could also write a small java server on the other machine, and have it tell you what you need to know with a socket connection. In this way, you have created your very own network protocol.

How to create and place two dropdowns in JSP page

How do I create two dropdowns side by side in a JSP page? Also, hw do I place them side by side so that there's no overlapping?

How do I create two dropdowns side by side in a JSP page?
Also, hw do I place them side by side so that there's no overlapping?
Also, how do I populate these dropdowns from the database and
include them both in the final page?None of those questions has anything to do with Javascript (just like this forum has nothing to do with Javascript).
If you want 2 select fields side by side, put them side by side in the HTML code or put them in adjacent table cells if the area they are in is forcing the second to the next line. This is all an HTML issue, nothing to do with JSP.
For the last question, you get the database data and you write the select options dynamically based on that. Get a result set, loop thru it.

Is it possible to create a file object from a resource?

Is it possible to create a File from a resource call rather than from a path
e.g.
File myFile= new File("C:/j2sdk/sampledir/mypage.htm");is how im doing it now
how can i call it from a resource something like
File myFile= new File(this.getClass.getResource("mypage.htm"));

you may be right
im trying to load a file into a string then display that string
my resource thingy isnt working anyway :s
[code[
URI pTURI=null;
URI pBURI=null;
try
pTURI= new URI(this.getClass().getResource("/resources/prev_header.htm").toString());
pBURI= new URI(this.getClass().getResource("/resources/prev_fullpac.htm").toString());
catch(URISyntaxException e)
warnUser("URI Error");
File previewTop = new File(pTURI);
