Problem in java.io.file reading

Hi
I have a servlet and it calls some classes which are kept in a jar file in WEB-INF/lib directory. With in one of the classes there is a IO file read happening. How should i read the file and what path should i put if the file is in WEB-INF/resources
my jar files are in web-inf/lib directory. How will i read the file and what should be the patch to be given
regards,
Sujesh

Hi Sujesh,
you can use getResource(path) or getResourceAsStream, see http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html
See http://www.slamb.org/projects/axamol/sql-library/manual/ch01s03.html for an example.
Hope it helps

Problem opening java code file

I downloaded some code for a slide out menu and am unable to open the file after unzipping it. Yes, I am a beginner and know near to nothing about java.
Here's the message that came up:
Script: C:\Documents and Setting\etc...etc
Documents\passion\ssm6_6\ssmitmes.js
Line: 1
Char:1
Error: Syntax error
Code: 800A03EA
Source: Microsoft JScript compilation error
So what's with that? I know it's my computer but I don't know where to go for answers so I thought here'd be a good start.
Any hints are greatly appreciated, thanks ya'll!!

There is some errror in The ssmitmes.js java script file. Just try to edit it and clear it.

Java.io.File and uppercase/lowercase

Hello,
I am running into a weird problem with java.io.File on a Windows system. My program needs to validate a path the user entered. Sometimes, the path will contain a directory name that should be uppercase, but which the user entered in lowercase instead, and the <File>.exists() returns true anyways. I know on Windows, on the command line, directory and file names are not case-sensitive, which is probably why it was done that way. But this is causing problems because once the path is (supposedly) validated, it is handed to a Unix program (case-sensitive), and if it's not really valid there, the user has no way of correcting it. Whereas if it were found as invalid in the Java program, I could pop up an error, and the user could correct it.
The bottom line is, is there a way of telling a File object to return false if the path name is not EXACTLY identical, on Windows? Or would I have to check the path myself, without relying on File?
Thanks in advance,
J-S

In this case, this is not acceptable, since the files or directories on disk can be in any case. I just need the entered case to be exactly the same as the files.
In other terms, I need File.exists() to return false if the case does not match. I would think there is a way to do this, since internally, the function checks if the operating system is Windows or Unix before doing the comparison, and acts differently in each case...
From http://java.sun.com/j2se/1.3/docs/api/java/io/File.html (see equals or compareTo method) :
"On UNIX systems, alphabetic case is significant in comparing pathnames; on Win32 systems it is not."
I would like to force the Unix way of doing.

Problem with Java and Zip Files

Hello there everyone. I have a problem with trying to zip up directories with empty folders in them. They zip fine with my code, but according to winzip, the number of files in the archive is incorrect. It's supposed to have a total of 288 files in it, but when it's zipped up, it only says 284. I mention specifically the "empty directories" note because the zipping works fine without empty folders.
Below is the code for the zip method:
public static void zip(File[] list, File zipfile, File zipRoot)
     throws IOException {
      if (!zipfile.exists()) {
               zipfile.createNewFile();
          else if (!zipfile.isFile()) {
               throw new IOException("The zip file, " + zipfile.getAbsolutePath()
                         + " is not a file.");
          if (list.length == 0) {
              LOG.error("The list of files to zip up is empty.");
          for (int i = 0; i < list.length; i++) {
               if (!list.exists()) {
                    throw new IOException("The file or directory, " + list[i].getAbsolutePath()
                              + " does not exist.");
          FileOutputStream fos = new FileOutputStream(zipfile);
          ZipOutputStream zos = new ZipOutputStream(fos);
          for (int i = 0; i < list.length; i++) {
               if (LOG.isDebugEnabled())
                    LOG.debug(i + ": " + list[i].getName());
               String entryName = getRelativeName(list[i], zipRoot);
               if (list[i].isDirectory()){
                    if (list[i].listFiles().length == 0){
                         ZipEntry entry = new ZipEntry(entryName + "/");
                         zos.putNextEntry(entry);
               else {
                    ZipEntry ze = new ZipEntry(entryName);
                    zos.putNextEntry(ze);
                    byte[] buffer = new byte[8096];
                    FileInputStream fis = new FileInputStream(list[i]);
                    int read = 0;
                    read = fis.read(buffer);
                    if (LOG.isDebugEnabled())
                    LOG.debug("\tFound " + read + " bytes.");
                    if (read == -1){
                         //empty file, but add it for preservation.
                         //zos.write(buffer,0,0);
                    while (read != -1) {
                         zos.write(buffer, 0, read);
                         read = fis.read(buffer);
                    fis.close();
                    zos.closeEntry();
          zos.close();
The files look like they're there, but I need the system to be able to determine the number correctly.
Here's the interesting thing: It zips the files, and then when I use the size() method for zip files in java, it says 284 files. But when I unzip, it says 288 again. It's like there's files missing when compressed, but when decompressed, they return. Note that the files are actually there. If I open the archive in a third party app such as Winzip AND Winrar AND IZarc, they all show 288 files. Any idea what would make the number of files appear incorrectly in a zip file when zipped by java with the code above? Thanks in advance.
- Chris

I figured out the problem. When zipping files in windows using winzip, it doesn't explicitly count folders as a "file/folder" as a file in itself. It will create the folders for files to go in, but the folder itself will not be 'counted' when you query the info of the file itself. You have more control of the zip file in java, and can count the folder as a file or not.

Static lookup lists:read data from a Java *.properties file

Hi
i need to make static lookup lists i am using read data from a Java *.properties file
i am using the Class "PropertyFileBasedLookupViewObjectImpl" that wrote by Steve Muench in ToyStore.
but i need to use the default language for that i update the loadDataFromPropertiesFile()
method to find the correct properties file
String temp=Locale.getDefault().getLanguage();
String propertyFile =
getViewDef().getFullName().replace('.', '/')+"_"+temp+ ".properties";
the problem:
For English(TEST_en.properties) it is good and working
For Arabic(TEST_ar.properties) read from correct file _ar.properties
but the dispaly character is wrong
When Debug
In the File 1=دمشق
In debug 1=/u32423

Depending on your use case you can either use a programmatic VO or directly expose the JV class as a data control.

I need your help again, i think this is a minor thing.
i have compiled the class file that i needed and i signed it too. but now it is giving me a new error and need your tip.
here is the java console loyout and my java file ((i think here is the problem in java file, something must be missing)).
thanks in advance for any help.

Synchronous File Read on Invoke Problem

I am trying to invoke file adapter to read the file once(Synchronous File Read) as described in Bpeltechadapter guide.
Read about Synchronous File Reading Capability here download.oracle.com/otndocs/products/bpel/bpeltechadp.pdf
Also read this: Re: Help! Three questions about FileAdapater. .
I get this process generation failed when i try to build it. The Empty_msg in inputvariable of invoke works but problem is with Charges_msg in output variable.
I am sure its something to do with ns but not getting it to work.

I would really appreciate your help here.

I face the same issue and I have given all permissions to the folder for OS user.
Because of this error my server is not starting up . Is there any way I can undeploy this composite to get my server running.
I cant do this from EM because SOA server is failing to start up.
I have tried removing it from $DOMAIN_HOME/deployed-composites but still when i try restarting the soa server the composite comes up there. Do we need to delete the entry some where else too. Kindly help.
Thanks,
Sri.

Problem With File Reading And Sorting

I'm having problems with a particular task. Here is what I have to do:
Write a program which reads 100 integers from a file. Store these integers
in an array in the order in whcih they are read. Print them to the screen.
Sort the integers in place using bubble sort. Print the sorted array to the
screen. Now implement the sieve of Eratosthenes to place all prime numbers
in an ArrayList. Print that list to the screen.
Here is the code I have so far:
import java.util.ArrayList;
import java.io.*;
public class Eratosthenes
    private ArrayList numbers;
    private String inputfile1 = "numbers.txt";
    public Eratosthenes()
        numbers = new ArrayList();
    public void readData()
        try {
            BufferedReader reader = new BufferedReader(new FileReader(inputfile1));
            for(int i = 1; i <= 100; i++) {
                String temp = reader.readLine();
                numbers.add();
        catch(Exception e)
This is the file reading part I have done but it doesn't recognise the line numbers.add() . It brings up the error - 'Cannot resolve symbol - method add(). Thats the first problem I have, can anyone see any way to fix it and to achieve the task. Also can someone help with the structure of a bubble sort method and a sieve of Eratosthenes method as I have no clue whatsoever. Any help will be greatly appreciated.

Ok, I've done that but I'm having another problem. When I'm printing an output to the screen, it prints 100 lines of integers and not 1 line of 100 integers. Can you see the problem in the code that is doing this?
import java.util.ArrayList;
import java.io.*;
public class Eratosthenes
    private ArrayList numbers;
    private String inputfile1 = "numbers.txt";
    public Eratosthenes()
        numbers = new ArrayList();
    public void readData()
        try {
            BufferedReader reader = new BufferedReader(new FileReader(inputfile1));
            for(int i = 1; i <= 100; i++) {
                String temp = reader.readLine();
                numbers.add(temp);
                System.out.println(numbers);
        catch(Exception e)
}

Problem in finding java class file

I am writting an application using servlets , JSP and a simple java classfile. The simple java class file is for connection pool and the name of connection pool class is DBConnectionManager . I am using JavaWebserver2.0 and I have placed this class file in .\JavaWebserver2.0\classes
I am placing my servlets in .\JavaWebserver2.0\servlets folder. Since I am using wfm package so my servlets are placed in .\JavaWebserver2.0\servlets\wfm .
The problem is with compiling the servlet placed in wfm folder . I get the following error:-
TestServlet.java:11:cannot resolve symbol
symbol: class DBConnectionManager
location: class wfm.TestServlet
However when I try to compile this class in servlets folder and remove the package statement from the source file, it compiles and works very fine. I am having lot of confusion as the class DBConnectionManager is in classpath but even then compiler gives error. The same class when placed in servlets folder and package statement is removed works very fine.
Kindly help.

Hi,
Is the DBConnectionManager class declared public?
Does the TestServlet import the package that contains the DBConnectionManager?
This is all I can come up with, with the current information.
Cheers,
--Arnout

Hello Sorry for the inconvenience, but I have a problem in Java I can not open files, audio chat, which type of jnlp after the last update of the Java 2012-004 Please help me in solving this problem.

Hello Sorry for the inconvenience, but I have a problem in Java I can not open files, audio chat, which type of jnlp after the last update of the Java 2012-004
Please help me in solving this problem.

Make sure Java is enable in your browser's security settings.
Open Java Preferences (in Utilities folder)
Make sure Web-start applications are enabled.
Drag Java 32-bit to the top of the list.
jnlp isn't an audio file format. It's just a java web-start program (Java Network Launching Protocol).

     char ch;
     while((ch=(char)in.readByte()) != 0x00)
          System.out.print(ch+"");
System.out.println();
     System.out.println("Integer 1 --> " + in.readInt());
     System.out.println("Integer 2 --> " + in.readInt());
     in.close();
     fis.close();
catch(Exception ex)
     System.out.println(ex.toString());
And I am getting following output:

Integer 2 --> 0
File file.ext is created in vc++
I am not getting integer data. Plz guide me for this problem.

If the "it" refers to a compressed (zipped) spreadsheet that you downloaded, the ".ods" extension is used by LibreOffice and probably OpenOffice (which are free versions of MS Office) for spreadsheets, which would suggest that wherever you're getting that "Excel" file from has switched to one of those programs. I've tried opening an .ods file from LibreOffice using MS Office 2013 for Windows and it does open though with a warning that some things have been changed. I don't know if Office for Mac can normally open .ods files. But if your need is to just open .ods files, take a look at LibreOffice.
