Problem in reading a resource file form JAR
Problem in finding a resource file from the jar.....
I have my code in the following directory structure
rootDir -
libDir -
XMLEntities.res
modelDir -
File1
File2
File3
Step1 - I create a jar file with root as modelDir and with all its files.
Step2 - I add XMLEntities.res also to the root of the jar
If I run my application using
java -classpath ;C:\aip_build\build_dm\rmi_server_files\dm.jar; model.data_model.ActivateDataManager
My application which uses Xalan.jar (lyong under ext directory in jdk) does not find XMLEntiries.res.
If I use my application as under without creating jar my application does find XMLEntites.res
Can anyone tell me why the application can not find the XMLEntities.res inside jar?
Sorry I missed one line............

something like :

I didn't do a complete inspection of your code (because it's too much and unreadable as it is) and I don't know POI, but creating a new HSSFWorkbook for each input file sounds fishy to me ... try re-using the workbook and just creating a new sheet in each iteration. -
Accessing resource files inside Jar using Fat Jar Eclipse plugin
Hi,
I want to develop single JAR file that uses a set of other JAR libraries. I am using Fat Jar Eclipse plugin. It works fine. However, I have problem to access resources files (i.e. rdf file) using relative path from my classes. Is there any idea how can I pack, set classpath and use relative path in order to make it works.
Thanks
ZoranI have solved this problem. The problem was in a way how I have trying to access it. It should be like:
URL fileURL = this.getClass().getResource("resource/myFile.rdf");

Problem in reading an Image file from a Output Stream.
I am having problem reading a JPEG file. Actually i am sending JPEG file using UDP from the client. I am using this code to convert to a byte array to transmit the file:
DataInputStream inStream = new DataInputStream(new FileInputStream("src/Bgamex.jpg"));
String str1 = inStream.toString();
byte[] bindata = new byte[65500];
bindata = str1.getBytes();
On the server side, I am using these lines to convert the bytes to a file again but it seems to be that its not working. Its making file but with a bigger size & like garbage in it, showing nothing:
byte[] buf = new byte[65500];
// receive request
DatagramPacket packet = new DatagramPacket(buf, buf.length);
socket.receive(packet);
buf = packet.getData();
java.io.OutputStream fos = new java.io.FileOutputStream("Bga.jpg");
fos.write(buf);
Could somebody lemme know the problem in converting the file.
Thanx.I propose you to perform this simple test to see by yourself: final String BIN_FILENAME = "somebytes.bin";
byte[] bin = {5, 4, 3, 2, 1};
FileOutputStream out = new FileOutputStream(BIN_FILENAME);
out.write(bin);
out.flush();
out.close();
byte[] bindata;
DataInputStream in1 = new DataInputStream(new FileInputStream(BIN_FILENAME));
String str = in1.toString();
in1.close();
bindata = str.getBytes();
System.out.print("Bytes read with in1>");
for (int i=0; i<bindata.length; i++) System.out.print(bindata);
System.out.println();
FileInputStream in2 = new FileInputStream(BIN_FILENAME);
bindata = new byte[65505];
int bread = in2.read(bindata, 0, in2.available());
in2.close();
System.out.print("Bytes read with in2>");
for (int i=0; i<bread; i++) System.out.print(bindata[i]);
System.out.println(); -
Problem in reading the excel file path in WINDOWs machine from UNIX environ
Hello friends,
My requirement is to read each row of the excel sheet and sent that row to the database. I have implemented it by using jxl and apache poi framework. locally in my WINDOWS machine it is working fine..
But when i deploy the code in UNIX machine. My application runs on a Unix server , trying to read the excel file in WINDOWS environment. I am not able to retrieve the file path. for ex : C:\Documents and Settings\sabbanik\My Documents\KARUNAKAR\excel.xls
I am getting error in this line
workbook = Workbook.getWorkbook(filepath)
Error message : input file not found.
Thanks in advance..You said: I am getting error in this line workbook = Workbook.getWorkbook(filepath) >
Based on this, I will assume you are trying to use OLE to access information about the Excel file. As mentioned by Andreas, your code will be executing on the server (Unix) and since Excel isn't on the server (and cannot be) an error will result. OLE can only be used in Windows environments (client or server). To access client side OLE calls and content, you need a java bean and Excel installed on the client machine. Oracle provides WebUtil as an option to writing your own Java Bean. To use this, you will need to be running Forms 10.1.2 or newer. Details can be found here along with a demo:

I have an xml file in a jar file other than the class that needs to read it. Most of teh posts I've seen reccomend using class.getResource to get access to the jar, but since the file is in a different jar this wont work.
I load classes using URLClassLoader and explicitely access the class I need from a specific jar by creating a url thusly....
jar:file:/" + workingDirectory + "/folder/jarfile.jar!/specificfolder/specificfile.class"
Is there a similar thing for reading an xml file for a jar?Have you tried:
"jar:file:/" + workingDirectory + "/folder/jarfile.jar!/specificfolder/specificfile.xml"

How to raplace resource files in jar file by other files?
Can I replace resource files (ex: some jpeg file which is in the jar file) when midlet execute on the phone. Is it possible?
Usualy, we use getResourceAsStream(filename) to get resource data as stream.
Is there some API function like 'setResource(filenmae,stream)' ??
Assume that I have a javaME application which displays some image in the jar file.
It is different from general image viewr program because it can display only
image file in the jar file (it means image file is resource file of java applcation).
In other words, when application executes, It shows always same image at first.
but I want that user can change image displayed if user wnat to do. I want to embed
authoring function into application. So user can replace resource file by other image files on the phone.
How to do that?I already told you, you CAN'T replace resources in a jar file.

Look into using rms to save content on a mobile device.
Now do you have anything else you want to ask?

Problem with reading from bin file into Vector
What am I doing wrong? It works fine to write the vector to the bin file and then read from it. But if I try just to read from the file it wont work.
Does anybody has any good advice to give when it comes to reading data form a bin file??
import javax.swing.*;
import java.util.*;
import java.io.*;

utFil.close();
ObjectInputStream inFil = new ObjectInputStream (new FileInputStream("HighScoreLista.bin"));
v =(Vector) inFil.readObject();
System.out.println (v);
inFil.close();
}Because what you are writing to the file is a vector, that is all you can get out. You are actually reading a single Object from the file which you can cast to a Vector, from which you can access the data stored inside. If you want to read the Spelare instances from the file, you will have to save them individually to the file. You will have to implement Serializable and look up the API to do that.

Help! Problem with reading objects from file
I wrote a "Library" program for an assignment, and one of the requirements is that the library store all of its information to file upon exit, and reload this information from file when run.
Well, the writing to file part is working. I'm using a FileOutputStream object and an ObjectOutputStream object. I can tell from the file size of the .dat file that information is going into it.
But what I can't do is read from file. For that, I'm using a FileInputStream and an ObjectInputStream. I keep getting this exception:
java.io.EOFException
at java.io.DataInputStream.readInt(Unknown Source)
at java.io.ObjectInputStream$BlockDataInputStream.readInt(Unknown Source)
at java.io.ObjectInputStream.readInt(Unknown Source)
at Library.readDataFromFile(Library.java:350)
at Library.<init>(Library.java:63)
at LibraryDriver.main(LibraryDriver.java:6)I looked this exception up and it says it's thrown when a data input stream unexpectedly ends....But I am instantiating the input streams just before I try to read from file:
fileInStream = new FileInputStream(libraryFile);
objInStream = new ObjectInputStream(fileInStream);
Object[] objectArray = new Object[objInStream.readInt()];Both input streams have methods that "return the number of bytes that can be read from this file input stream without blocking". Just for kicks, I tried writing that number to the console.
For the FileInputStream, I get 404 bytes.
For the ObjectInputStream, I get 0 bytes.
So I guess it's a problem with the ObjectInputStream? Anyone have any suggestions as to how I can fix this, please?Yep, here's the relevant code from the writeToFile() method:
for (int i = 0; i < libraryAuthors.length; i++) {
currentAlphaAuthorList = libraryAuthors;
for (int j = 0; j < currentAlphaAuthorList.size(); j++) {
currentAuthor = (Author) currentAlphaAuthorList.get(j);
objOutStream.writeObject(currentAuthor);
objOutStream.flush();
objOutStream.close(); -
Problems on reading PCM into digital form
Hi,
I'm now on a project doing heart rate detection.
Due to the project just started, therefore I do not got any device to measure my own heart rate, but I will be making up some PCM(analog) data, and try to read that into digital form and give me results of the heart rate.
I'm not sure am I on the right track now or not,
what I'm doing now is trying to convert a ".wav" into bytes array, then it should give me some data, however, I'm not sure how to relate that data into heart rate.
Please leave me any comment if u think it might help please.
Thanks,
tillI'm not too sure what should be the .wav should be, however, according to this acticle I got it from the web:
_2.1 Signal acquisition_
ECG signal frequency content lies between about 0.05Hz and
500Hz and has amplitude of few mV. The acquisition is provided
to be performed in three different ways: (i) using direct electrode
measurements, (ii) using ECG equipment with analogous output;
and (iii) using ECG equipment with digital output. For the first
two cases, a sampling rate of 8 kHz is assumed. In the third case,
the acquired discrete signals are accordingly resampled.
_2.2 Modulation_
The bandwidth of the phones voice channel is limited to the
range 300Hz-3300Hz. The signal amplitude at the microphone
input should not exceed 100mV. Modulation is performed through
multiplication with carrying sinusoidal signals. Five 500Hz-wide
channels are packed within the 500Hz-3000Hz band. The
resulting signal is appropriately refined in amplitude and directed
to the modulators output.
_2.3 Digitizing, storing and sending_
The complex signal is band-limited to 3300Hz. Therefore, a
standard sampling frequency of 8 kHz is used for its digitization.
A JAVA application performs that and in order to store the signal
intact, the signal is recorded in a lossless format such as pulsecode
modulation (PCM). The WAV audio file format implements
PCM and is used to store the recorded modulated ECG signals.
Once stored, the signals can be visualized, processed and sent by
the mobile phone.
Mobile phones firmware is accessible by programming
languages as C++ and JavaTM. Most mobile phones support
JavaTM runtime called Kilobyte Virtual Machine (KVM) [6]. This
language provides the ability to build a GUI application that could
support all the stages of recording, storing and transmitting of the
ECG signal. JSR-135 contains libraries of JavaME, which are
useful for capturing audio from the microphone's port of a mobile
phone. The above mentioned platform was used to create the
application software.
_2.4 Demodulation_
The procedure of demodulation is performed at the physicians
phone, following the reverse track of modulation. A digital band
pass filter is used to separate the spectra, corresponding to the
individual ECG signals. The filtered signal was then multiplied by
the corresponding carrier frequency and filtered with a low pass
filter, resulting in the original signal. The demodulated signals can
be stored in separate WAV files in the physicians phone.
_2.5 Matlab simulations_
In order to prove the principal feasibility of the approach, the
signal acquisition, processing and transmission procedures were
simulated in MATLAB. Five preliminary recorded ECG signals
were directly loaded and used. The signals acquisition parameters
were: 8-bit values, sampling rate of 250Hz and duration 10S.
Modulation and demodulation were programmed and performed
in a numerical way. Modulation was done by multiplication of the
ECG signals with carrying sinusoidal signals of frequencies
500Hz, 1000Hz, 1500Hz, 2000Hz, and 2500Hz. The
demodulation included first separating the spectrum of each
individual signal with the help of 4-th order 400Hz-wide bandpass
Butterword filters centered on the corresponding carrying
frequency. Next the filtered signals were multiplied with the same
carrier signals and eventually filtered with a low pass 4-th order
Butterworth filter (fc=200Hz).
btw, the system need to be implement into Symbian phone at the end,
but I'm just now testing on the PC atm =)
according to this article, what kind of wav I should be using ??

Problem in Reading a .PDF file
HI Friends,
I am reading a .pdf file from within java program using its java.io package.
I am able to read the file, but when I print the line read from file on to the screen, it all garbage. Its not in readable characters.
I guess its reagrding mismatch in Charcter Sets of original file and the stream with which I m reading the file.
So,if u know the solution plz suggest me.Hello Simple@java
Here's an exemple of a class that opens the File "rapport.pdf" located at the same place as the class.
Of course AcroRd32.exe is the name of Acrobat Reader which allows to read pdf files. You can get it on : adobe.com(http://www.adobe.com/products/acrobat/readstep2.html)
You will change "rapport.pdf" by the name of your pdf file.
Then execute "test()".

any suggestions
<Thanx in advance >while (in.readLine() != null)Right here, you are reading in the file, but you don't store the content.
temp = in.readLine();By the time you reach here, you have already read in the whole file, so there is nothing left to read. That's why temp is assigned null -

DAT File
Wayne Gretzky 99 CAN 8/13/87 R 120 222
Joe Sakic 19 CAN 9/30/77 L 123 210These are all in early development, we seem to have the idea down but keep getting the odd FileNotFound exception when making an object of the ImportHockeyPlayers class with the parameter of the DAT file.
We might even be on the wrong track with an easier way to do this. To give you an idea of what we want to do...read from the file and be able to pretty much plug in al lthe players into a GUI with a list of the all the players.
Thanks for your time.Thanks for the tip on the date format...good to
know.
public static void main(String[] args)
GUI gui = new GUI();
ImportHockeyPlayers ihp = new
ImportHockeyPlayers("HockeyPlayers.dat");
}It's just being called in the main.
Throws this error:
GUI.java:39: unreported exception
java.io.FileNotFoundException; must be caught or
declared to be thrown
ImportHockeyPlayers ihp = new
ImportHockeyPlayers("HockeyPlayers.dat");
^This error is simply telling you that an exception may occur so you must enclose it in a try catch block or change the main method to throw the exception as follows
public static void main(String[] args) throws
java.io.FileNotFoundException {
GUI gui = new GUI();
ImportHockeyPlayers ihp = new
ImportHockeyPlayers("HockeyPlayers.dat");
}or
public static void main(String[] args) {
GUI gui = new GUI();
try {
ImportHockeyPlayers ihp = new
ImportHockeyPlayers("HockeyPlayers.dat");
catch (FileNotFoundException e) {
System.out.println("error, file not found");
}I would reccomend the second approch, it will be more helpful in debugging, also make sure that the capitalization of "HockeyPlayers.dat" is correct
hope that helps -
Unable to read a resources file from my page
Hi,
I am trying to read a file from the project resources and I can't have access to the physical file. I have the following code in my page:
javax.faces.context.ExternalContext ec = this.getExternalContext();
URL url = ec.getResource("/resources/displayPassengers.xsl");
InputSource inputSourceXSL = new InputSource(url.toExternalForm());
InputStream inpStreamXSL = null;
if (inputSourceXSL.getByteStream() != null) {
log("Loading xml file: " + url.toExternalForm());
inpStreamXSL = inputSourceXSL.getByteStream();
} else {
log("Unable to extract URL from Page context: WEB-INF/displayPassengers.xsl");
The url is not null.
The inputSourceXSL is not null and inputSourceXSL.getByteStream() is always null.
Please let me know how to access the file.
Rgrds.this should work
InputSource inputSourceXSL = new InputSource(url.openStream()); -
Problem in reading from the File
Hi,
I have a dataset.txt file which is as follows:
2
4
1 2 3 4
2 3 4 5
3 4 5 6now that I need the value that is present in the 1st line of the file(ie;2) and value present in the 2nd line of the file(ie;4), upon that i'll be reading the data into an array.
for this task of mine to accomplish , i'm using the following code
String line_1;
String line_2;
int first_line,second_line;
DataInputStream dis1 =null;
DataInputStream dis2 =null;
System.out.println("Print this");
try
File f1=null;
f1 = new File ("dataset.txt");
File f2=null;
f2 = new File ("dataset.txt");
FileInputStream fis1 = new FileInputStream(f1);
FileInputStream fis2 = new FileInputStream(f2);
dis1 = new DataInputStream(fis1);
dis2 = new DataInputStream(fis2);
BufferedReader line1 = new BufferedReader(new InputStreamReader(dis1));
line_1=line1.readLine();
first_line=Integer.parseInt(line_1);
System.out.println("Value of First_line is: "+first_line);
BufferedReader line2 = new BufferedReader(new InputStreamReader(dis2));
line_2=line2.readLine();
second_line=Integer.parseInt(line_2);
System.out.println("Value of Second_line is: "+second_line);
}//end of try
catch(Exception e)
{e.printStackTrace();}The problem here I'm having is, when i'm printing I'm getting the follow result
Value of First_line is:2
Value of Second_line is:2Instead of printing the value of Second_line as 4, it is printing 2.
Why is this happening?
Any kind of response is appreciated.
Thanks is advanceYou dont have to make 2 data stream objects of the file.
To read two lines you can just do with it object
BufferedReader line1 = new BufferedReader(new InputStreamReader(dis1));and just call readLine( ) method twice
line_1=line1.readLine();
line_2=line1.readLine();
