4Add the line:
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar
Then, run the command "source ~/.profile" and then the jar file should be able to run.

Running .jar files in linux on double click

Hi,
i needed a solution to run the jar files on double click in linux system.Necessity is mainly because when i run the jar file by java -jar myapp.jar in terminal it works fine .Iam running my app continuosly in system tray(a server kind).But if i close the terminal my app exits.
How to resolve this ?

I am taking a SWAG.....it sounds like your problem is how to run a java app without a terminal window. So as I recall, there is some way in Linux to enter a command and have it execute in a new process. I don't recall the syntax but maybe putting a '&' character in the command line? Anyway, you should be able to use the method and use "javaw" instead of "java" to launch your app. You should be able to do this in a batch file too. Something like, javaw -jar yourjar.jar &

Can't run .jar file with JavaSE

Hello.
I'm trying to run a .jar file with JavaSE Binary, just like I did with Windows. I Ctrl+Rclick and pick "Open with..." and there is no such option. I've been searching the whole day for a solution, I kept getting "Open Java Preferences... put on top of the list" and things like that. There is no "Java Preferences" in the Utilities folder, and nothing related to my problem in "Java Control Panel" in System Preferences. Yes, I have Java 7. I just need to run this file with Java. How?
Thanks in advance.

Strange......problem with batch file in java

hi,
my problem is that i have created one bat file and i want to run that file in java but it is not running properly. the problem is .......
i have created one bat file named "file1.bat" & content of this file is as follows :-
[ ag > b.txt]
(and content of file "ag" is "aaaaaaa" )
now i am trying to run this bat file in java and want to read this b.txt in which i have redirected the content of file "ag".
for that i have written the code like this:-file name is "runbf.java"
import java.awt.*;
import java.lang.Runtime;
import java.io.*;
public class DriveVol
public static void main(String args[]) throws IOException
int volumn;
Runtime r = Runtime.getRuntime();
r.exec("ss.bat");
FileInputStream fp;
fp = new FileInputStream("b.txt");
flush();
do
volumn = fp.read();
System.out.print((char)volumn);
}while(volumn != -1);
fp.close();
when i am running this programme first it is not displaying the content of b.txt. but when u run this prog twice then only it 'll give the correct ans. what i mean is, i'll explain that stepwise.
1. as per my prog. -- r.exec("aa.bat") -- this line 'll execute first. so content of ag 'll redirect to file "b.txt"
2. now i am trying to read the file "b.txt" using FIleInputStream...
3. but first time it is giving some garbbage value.when i give --c:jdk1.3\bin>java runbf
4. but the very next moment when again i run that file - c:jdk1.3\bin>java runbf
it 'll give the correct value.
5. again when i change the content of file ag(suppose "bbbbbbb"). & try to run "runbf.java" like this-
-- c:jdk1.3\bin>java runbf --
6. then it 'll display the value "aaaaaa". now when again i run that file
it 'll give the correct value "bbbbbb"
7. so every time i have to run that "runbf.java" twice for printing the correct
value of file "b.txt"
so what i think is that, it is not refreshing the data of file "b.txt". after executing this line
r.exec("aa.bat");
so is there any method to refresh the data of file "b.txt"??????
i think u 'll try to understand my problem...
so please help me to get the ans.......
thx.........

pls can anyone hlp............

Running exe files from java applications

Hello All,
Is it possible to run executable files from java applications?

HI,
I tried to launch a MS Word application using runtime.exec but it gives me some problem
The foll. code to launch a txt file using notepad works.
Runtime rt = Runtime.getRuntime();
String[] callAndArgs = {"notepad.exe","C:\\coo7\\wizard.txt"};
Process child = rt.exec(callAndArgs);
However, oif I try to launch a MS Word application, it asks for the entire path of WINWORD.exe, (unlike just specifying notepad.exe as the first argument in String[] callAndArgs) and this can vary from one machine to another.. how do I get around this?
The foll. code snippet works but the complete path of where WINWORD.exe might be installed on any machine, is not fixed:-(
Runtime rt = Runtime.getRuntime();
String[] callAndArgs = {"C:\\Program Files\\Office\\Office10\\WINWORD.exe","C:\\coo7\\wizard.doc"};
Process child = rt.exec(callAndArgs);
Any idea/suggestions pls..

Append to jar file using java codings

Hi,
I have codings which could create jar file and write datas in it. but i need to append datas to existing jar file using java codings.Here i have attached my codings which will write datas to new jar file. when ever i use this my existing contents gets overritten. wat can i add to this to append.
FileOutputStream stream = new FileOutputStream(archiveFile,true);// archive file is jar file name
     JarOutputStream out = new JarOutputStream(stream, new Manifest());
JarEntry jarAdd = new JarEntry(tobeJar.getName()); // tobejar is a file to write in jar.
jarAdd.setTime(tobeJar.lastModified());
               out.putNextEntry(jarAdd);
               // Write file to archive
               FileInputStream in = new FileInputStream(tobeJar);
               while (true) {
               int nRead = in.read(buffer, 0, buffer.length);
               if (nRead <= 0)
               break;
               out.write(buffer, 0, nRead);
               out.closeEntry();
out.close();

JarInputStream in = new JarInputStream(new FileInputStream(oldJarName), true); // oldJarName is the JAR that contains all the files we want to keep
JarOutputStream out = new JarOutputStream(new FileOutputStream(tempJarName)); // this is your "out" variable
// copy the files from the old JAR to the new, but don't close the new JAR yet
JarEntry inEnt;
while ((inEnt = in.getNextJarEntry()) != null) {
JarEntry outEnt = new JarEntry(inEnt); // copy size, modification time etc.
byte[] data = inEnt.getSize();
in.read(data); // read data for this old entry
in.closeEntry();
out.putNextEntry(outEnt);
out.write(data); // copy it to the new entry
out.closeEntry();
// now write an entry for the file we want to append - this is the OP's code
JarEntry jarAdd = new JarEntry(tobeJar.getName()); // tobejar is a file to write in jar.
jarAdd.setTime(tobeJar.lastModified());
out.putNextEntry(jarAdd);
// Write file to archive
FileInputStream in = new FileInputStream(tobeJar);
while (true) {
int nRead = in.read(buffer, 0, buffer.length);
if (nRead <= 0)
break;
out.write(buffer, 0, nRead);
out.closeEntry();
// and *now* we close the new JAR file.
out.close();
// We then delete the old JAR file...
new File(oldJarName).delete();
// ... and rename the new JAR file to use the old one's name.
new File(tempJarName).renameTo(new File(oldJarName));

Writing into a jar file through Java program

Is there a way to get a file from a jar (for ex. a properties file) make changes to it on the fly and write the same file back to the jar through a Java program?

I cannnot give u exact code as i am bit busy..but i am giving close to exact
below is code for reading contents of jar file
import java.io.*;
import java.util.jar.*;
public class JarRead {
public static void main (String args[])
throws IOException {
if (args.length != 2) {
System.out.println(
"Please provide a JAR filename and file to read");
System.exit(-1);
JarFile jarFile = new JarFile(args[0]);
JarEntry entry = jarFile.getJarEntry(args[1]);
InputStream input = jarFile.getInputStream(entry);
process(input);
jarFile.close();
private static void process(InputStream input)
throws IOException {
InputStreamReader isr =
new InputStreamReader(input);
BufferedReader reader = new BufferedReader(isr);
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
reader.close();
now here say u have test.jar which contains test.txt (file)
then
java JarRead test.jar test.txt
will print content of text.txt
now in ur case u write content of each file in some other file modify it there and then create a jar file from those files using jaroutput stream .....
this may not be all clear ..but what to do..bit busy...u are welcomed to make changes in above stratergy....n queries if any after using above stratergy and/or your great brain...
