FileNotFoundException problem
i have a simple program which uses FileInputStream and makes a copy of that file by using FileOutputStream. I am sick of getting following errors
Exception in thread "main" java.io.FileNotFoundException: C:\abc\abc.jpg (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:106)

at socketprogramming.ClientT.main(ClientT.java:15)
I am 100 percent sure that the file exist in the location.checked many times with file name ...everything good..pls look at my code below..

fileout.write(b);

}I would appreciate your help or any suggestion to fix this!

It specifically states: "If the named file does not exist, is a directory rather than a regular file, or for some other reason cannot be opened for reading then a FileNotFoundException is thrown."
I suggest you try setting up a File object first and check File.exists(). If that returns true, then the problem is not that it can't find the file.

PDF generation : FileNotFoundException problem
Hi all,
I'm developing a dynamic PDF generation module in web application using iText framework. This module creates PDF on the server side then sends it to the client. Sometimes, Even though the PDF file is created on the hard disk, I got FileNotFoundException when calling the servlet that sends it.
My program is very simple (no thread used) :
1- The client calls enters some inputs,
2 - The iText based class generates the PDF,
3 - The PDF created is saved as an attribute in the client session (HttpSession).
4 - The request is redirected to servlet that sends the PDF.
What could be the problem ?
thx,In fact, I don't know what you mean by:
3 - The PDF created is saved as an attribute in the client session (HttpSession).What do you mean by this? Did you save the proprietry PDF object? Or the java.io.File object? If it is the PDF object, does its class implement java.io.Serializable?
Um ... Here are some suggestions ...
First of all, make sure that the file really exists there.
Secondly, try to write a Java SE program to read the file using the absolute path you provided.
Then, if the Java SE program works, I think the reason may be that you haven't closed the "OutputStream" which writes the PDF file, or the security settings of your JSPServer prevents you from getting the file.

Any idea? No luck with increasing the document disposal timeout or sweep interval...Our pdf-files is about the size of 130 kb.
With the current configuration we have set the document max-inline-size to 512 kb. Now the FileNotFoundException to the GDS has disapeared. But i still wonder why this error was shown when we used the GDS instead on the memory.....
Could it be problem with Synchronizing clock times in our cluster..?
Now and then we have another FileNotFoundException ERROR in the tmp-directory. In what way are LC using this directory..?

Problem with FileNotFoundException
Hi. Sometimes in my application i have problems with FileNotFoundException, but file which i want to open exists. In the documentation I found that:"It will also be thrown by these constructors if the file does exist but for some reason is inaccessible, for example when an attempt is made to open a read-only file for writing." What can be another reason that the file is inaccessible?
EJP wrote:
That doesn't happen unless the file is currently in use ...I would have to dissagree with you there. Not frequently, but on occasioin, I have had windows just not release a lock that is has on a file. I've had this happen with various editors--Word and Notepad are ones that recently come to mind. It has also happened to me doing a copy from one folder to another. Windows Media Player has also expressed a problem and also Excel and Access. I have had these problems in Windows 7, XP, and other previous Windows versions. And please do not think this is limited to accessing a file with Java--it has expressed in various MS development tools and even just using MS products--no programming outside of the shrink wrap MS product was used. -

File and FileInputStream problem
Hi all
I have downloaded from developpez.com a sample code to zip files. I modified it a bit to suit with my needs, and when I launched it, there was an exception. So I commented all the lines except for the first executable one; and when it succeeds then I uncomment the next executable line; and so on. When I arrived at the FileInputStream line , the exception raised. When I looked at the code, it seemed normal. So I want help how to solve it. Here is the code with the last executable line uncommented, and the exception stack :

Thank you very muchOne easy way to send a file through RMI is to read all bytes of a file to a byte array and send this array as a parameter of a remote method. But of course you may have problems with memory when you send large files. The receive is simillary.
Other way is to split the file and getting slices of the file, sending slices and re-assemble at destination. This assume that the file isn't changed through the full transfering is concluded.
I hope these could help you. -
Arraylist.add() problem
Hi,
I'm trying to read a CSV text file into an arraylist.
I can read the text file fine, its just when it gets to the actual arraylist.add() part it just .. .. doesn't work. It can print the values from the CSV file no problem. I'm sure my syntax is fine, everything compiles. I've read it and double checked it and checked it again.
It just doesn't work .. I don't know why.
The arraylist I am trying to read into is
ArrayList<Customer> customers = new ArrayList<Customer>();Within other parts of the program I can read in dummy data, eg
customers.add(new Customer(01, "Jims Mowing", "16 Long Grass Street", "Thorndale", "123-4567", "[email protected]"));
but suffice to say, yes, it is kaput.
* READING THE CUSTOMER TEXT FILE INTO THE ARRAY LIST
private void custFileToArray ()

while (line !=null) // test for end of file (EOF)

// close file

Hi,
Cheers for the replies & the printStackTrace tip.
The thing is it's not actually throwing up any errors or crashing. It's acting as if everything is AOK - but since it then says there's nothig in the arraylist there must be a problem ... somewhere.
Sorry if I've mis-understood what you were saying
Here's the dummy data I'm using just incase it's at all relevant

Hello,
I am having a problem with a program I am trying to write. The idea of the program is to:
A) read a list of movies list from a text file
B) create an object for each movie using the information from the text file
C) place the objects into an arrayList

String tempYear = array [1];
String tempRating = array [2];
String tempFormat = array [3];

public ValidMovie(String tTitle, String tYear, String tRating, String tFormat)

Bamboozled 2000 2 DVD
What Lies Beneath 2000 1.5 DVD
Beneath the Planet of the Apes 1970 1 DVD
You Can Count On Me 2000 3.5 Theater
And finally this is the result when I run the code:
item at index 1 is: Bamboozled 2000 2 DVD
item at index 1 is: Bamboozled 2000 2 DVD
item at index 1 is: Bamboozled 2000 2 DVD
item at index 1 is: Bamboozled 2000 2 DVD
I am sure that it is something simple that I am overlooking but I cannot figure it out. When I change the index in the code:
System.out.println("item at index 1 is: " + movieList.get(1));to 0 or 2 or 3 then result is the same, it will just show the first movie in the text file. Any help would be greatly appreciated. ThanksThanks for the reply, it helped but I am now getting 4 of each of the movies after adding you suggestion. This is much better now I just need to figure out why the loop is causing the extra copies. Thanks again :)

Reading into ArrayList problem - what is wrong?
Hi, I am trying to read a list of strings into an ArrayList and am having some problems. I have created a main() which at the moment does nothing, its just to make sure that the array's content is genuine (meaning consistent with the string in the text file) so I am having it simply printed out to screen. The error I am getting is "cannot resolve symbol, variable array" by my compiler (Jcreator). I will paste the code below:
import java.io.*;
import java.util.*;
public class hostList{
public hostList()
try
File input = new File("hosts.txt");
BufferedReader in=new BufferedReader(
new InputStreamReader(new FileInputStream(input)));
ArrayList list=new ArrayList();
String line;
while((line=in.readLine())!=null)
list.add(line);
String[] array=new String[list.size()];
list.toArray(array);
in.close();
catch(FileNotFoundException e)
System.err.println("File not found...");
catch(IOException e)
System.err.println("IO Problem");
}//hostLst()
public static void main (String [] args){
System.out.println("Array content:");
System.out.println("array " + array[0]);
for (int i=0; array[i] !=null; i++)
System.out.println(array);
}//main
}//class
Also, how would I use the array objects in another class, say class B. How can I access the arrays in class B so that i can use its methods? eg. array[i].doSomething(); where doSomething() is a method in class B. What libraries would i need to import (if any) ?
Help is appreciated, thanks.this code wont compile bcas in main method u r not creating the object of this class also the var array is not globally declared hence wont be accesibile outside
u can try this modified code
import java.io.*;
import java.util.*;
public class hostList{
String[] array=null;
public hostList()
try
File input = new File("hosts.txt");
BufferedReader in=new BufferedReader(
new InputStreamReader(new FileInputStream(input)));
ArrayList list=new ArrayList();
String line;
while((line=in.readLine())!=null)
list.add(line);
array=new String[list.size()];
list.toArray(array);
in.close();
catch(FileNotFoundException e)
System.err.println("File not found...");
catch(IOException e)
System.err.println("IO Problem");
}//hostLst()
public static void main (String [] args){
hostList h=new hostList();
System.out.println("Array content:");
System.out.println("array " + h.array[0]);
}//main

[Solved] Installation problem on HP-UX

Have you got any idea what is going wrong there.
Thank you VERY much in advance and sorry for my bad English (this is not my native language).

You have to login https://support.oracle.com/CSP/ui/flash.html and you have to CSI account.
This site is oracle site for tech. documents for can rise SR etc.. for more details please check Re: Installing Oracle Database 10.2.0.4
you need to customer support identifier which is called CSI for can login metalink(https://support.oracle.com/CSP/ui/flash.html)
If you dont have metalink account there is no legal way to see this doc
Pretty simple process:
1) You purchase a perpetual or term license from Oracle;
2) At the beginning of the period, during the valid term you purchase
Support for the period (1 year);
3) Oracle sends you the CSI.
Easy to do at http://store.oracle.com armed with a credit card.
Sorry, I'm sure you'll think I'm stupidNo I dont think mate :)

RE: [iPlanet-JATO] Re: Deployment problem
Chidu,
I think that you are mired in the very common confusion of the default
behavior of the ApplicationServletBase.parsePathInfo() which will determine
the controlling/handling ViewBean via a URL design pattern. Lets take a look
at the URL
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.jsp
is decomposed as follows:
/NASApp -> well, this is long story but is absolutely necessary, welcome to
iAS
/MigtoolboxSampleAppWar -> is the web application name, taken as the name of
the WAR file when there is no EAR file (this allows the Servlet/JSP
container to deferences the web application root under
<ias>/APPS/modules/MigtoolboxSampleAppWar) I think this part of the URL is
called th Context Path
/MigtoolboxSample -> is the Servlet Path, and will either directly reference
or match a Servlet Mapping
for instance
<servlet-mapping>
<servlet-name>MigtoolboxSampleServlet</servlet-name>
<url-pattern>/MigtoolboxSample/*</url-pattern>
</servlet-mapping>
tells the Servlet Container that the Servlet Path
/MigtoolboxSample
maps to the Module Servlet MigtoolboxSampleServlet
This is how EVERY request makes its way to the "front controller" pattern in
JATO. It is fundamental to JATO Applicatioan that every request pass
through the ModuleServlet.
every else on the URL past the Servlet Path is the PATH INFO. Based on this
understanding, you will see why the
ApplicationServletBase.parsePathInfo()
is so important. In parsePathInfo() the PATH INFO is compared to the design
pattern
/VIEWBEANNAME*
to determine the handling ViewBean from the first String Token in the path
info. For instance, the starting URL of the Sample Application is
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage
The PATH INFO is [IndexPage]
and IndexPage[ViewBean] is the handling ViewBean. Therefore, any simiarl
URL like
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.jsp
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.matt
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.mike
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.chidu
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.XXX
will all result in the same handling View Bean
IndexPageViewBean
It is very important to understand that you CANNOT hit the JATO JSPs
directly. You must hit the "front controller" ModuleServlet which will
always delegate control to the handling ViewBean (a la, the "service to
workers" pattern)
You can attempt to hit the JSP directly but you need the right J2EE URL
/NASApp/MigtoolboxSampleAppWar/MigtoolboxSampleApp/MigtoolboxSample/IndexPag
e.jsp
this URL will directly hit the JSP. However, you will recieve an error
because the JATO framework quickly determines that there is no
RequestContext in the HttpRequest attributes and assumes that the "front
controller" was bypassed. Try it. You will get ERROR.
Lets go back to what you are trying to do, place Models and Viewbeans in
separate directories. I recommend that you move the Models. Models are
ONLY referenced by TYPE via the ModelManager, the compiler will ensure that
your code is correct and matches the packages, file locations, import
statements, etc. ViewBeans, on the other hand are related to the
ModuleServlet their are contained in and are loaded via type names according
to a design pattern.
if you want to separate models and Viewbean then simply move the Model and
make sure everything compiles.
you cannot move the ViewBeans
if you do want to move the JSP peers of the Viewbeans, then you can put them
anywhere in the web application doc root. When you do, update the
DEFAULT_DISPLAY_URL as Mike suggested
matt

Chidu,
Did you have it running fine in the original default configuration, before
you started changing things around? The URL should not access the .jsp
directly. The URL should look more like this
"/NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage", without the
.jsp.
Also, please read the "Migration Tech Notes" document that is
linked to the
main doc index page. There is some information in there related
to trying to
run the sample application under iAS (see Tech Note 4 in
particular, "Note
on running the iMT "MigtoolboxSample" in iPlanet Application Server )

Hi Mike,
I tried changing the url in all the viewbeans to reflect the new sub-
directory for the viewbeans(I have placed the jsps and viewbeans in
a sub-directory under MigtoolboxSampleApp/MigtoolboxSample). But I'm
still not able to get access to the jsps. I basically see the
message "GX Error Socket Error Code missing!!" error on the browser
thrown by iPlanet, but the log doesn't tell me anything. Does the url
which I give to access the jsp change accordingly, i.e., should I
give something other
than /NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.jsp.
If I try to use any other url other
than /NASApp/MigtoolboxSampleAppWar/MigtoolboxSample/IndexPage.jsp, I
see the FileNotFoundException in the log.
I guess I'm still missing something.
Thanks for your help.

Did you also adjust the following member in each of the ViewBeans?
public static final String DEFAULT_DISPLAY_URL=
"/jatosample/module1/Index.jsp";
Try adjusting this to be consistent with your new hierarchy.
Also, if you still have problems, send us the error message thatyou recieve
when you try to access the page. That would help.

I tried seperating the two in the MigtoolboxSampleApp application
provided by JATO. I changed the package and import statements
accordingly in the viewbeans, jsps and the models. But when I

Problem with downloading file from FTP server
Hello all
I have uploaded a file from an application i developed and i want to download this file from another application. The code is
public static void FTPcon() throws FtpException{
String hostname = "my.ftp.server";
String username = "myusername";
String password = "mypass";
Ftp ftp = new Ftp(hostname,username,password);
ftp.setHostname(hostname);
ftp.setUsername(username);
ftp.setPassword(password);
ftp.connect();
ftp.setBinary();
ftp.download("file.dat");
ftp.disconnect();
}The error i receive is java.io.FileNotFoundException: public.dat (The system cannot find the file specified) but the file is on the server.
Thanks in advance for any helpCotton thank you for your reply
Any other sugestions please?The server disagrees. So...
- the file does not existThe file exists.I checked it with an FTP client program.
- the file has a different nameThe file name is correct
- you are connected to the wrong serverI am connecting to the correct server
- you are in the wrong ftp directoryThe file is placed in the home directory
- the ftp library you are using is broken (less
likely)I am using the library from jscape.I dont think is broken because i can upload the file from the first application.
>
FTP isn't somehow broken in Java. I use it all the
time. The problem is something listed above. I would
check all of the first four if I were you because
that's most likely where the problem is.Message was edited by:

Redeploying an EJB onto OAS 4.0.8.2 from JDev 3.1 - problem
My previous message should have had in the topic, OAS 4.0.8.2 instead of OAS 4.0.8.3.
So, I'll explain my problem again:
I'm trying to redeploy an EJB onto the OAS, and I get the following error:

I tried to go delete the client.jar file from the OAS machine, and it won't let me saying it is a sharing violation (File is in use). I deleted the EJB from the OAS, stopped the OAS, and still I cannot delete the client.jar file.
First, why couldn't I redeploy, and second, how do I delete the _client.jar file?
Thanks!
