Compiling a jar or zip file with Ant

Hi,
I am using Java 1.4.2 and Ant 1.6.1
I am trying to use the javac task to compile a jar file and a zip file directly (i.e. they contain compressed .java files) instead of uncompressing them first and then compiling them. Is it supported in Ant?
i.e.
<target name="compileinit">
<mkdir dir="${compile.outdir}"/>

<javac destdir="${compile.outdir}" debug="on">
<classpath refid="classpath"/>
<src refid="srcpath"/>
<include name="jarfile.jar"/>
<include name="zipfile.zip"/>
</javac>
</target>
Thanks!

Jar (or Zip) file with problems in accents, special characters

Hi! I've a servlet that creates a jar (or zip) file and then send it. My problem is that when I create an entry in which the filename has special characters such as accents, when I unjar or unzip de file, it brings a lot of garbage characters. For example, the nex entry:
Ex�menes.doc
when unzipped is:
Ex?�menes.doc
I've tried a lot of things:
-Setting the locale to ES, MX
-Replacing all the letters with special characters with its unicode (like s.replace('�','\u00E1')
-Trying to convert it to UTF8 (new String(path.getBytes(),"UTF8") )
-Replacing the file separator char (according to a workaround that I found in the bug database)
But nothing of this worked, alone or together. I've read that this is (or was) a bug in the API, but don't know if a solution has been found.
Any help will be greatly appreciated!

Classpath to .jars inside .zip files

I had post something similar to this but this time it's another idea (and another problem) - so, this is not cross-posting.
I have this .zip file with 25 .jar files, I want to use it in my Manifest file, but it seems that when the classes are in the .jars and the .jars are in a zip file they are not reached by the Classloader.

Is is possible to do that? (.jars inside a zip) Or am I dreaming here?

You would have to write your own custom classloader to do this, which is what http://one-jar.sourceforge.net/ tries to do.

Decompress ZIP file with Password

Hi all,
Does anybody know how to decompress a ZIP file with password protection?
I have a decompress code, but I don't know how to insert the pass.
Any solution?
Regards

I'm running out of suggestions over here.
Your exact command line yields this result:
zip warning: name not matched: in.txt
zip error: Nothing to do! (out.zip)
Well, it should, as I don't have an in.txt. Handing it an existing file, I get this:
zip -P pass out.zip result.txt
adding: result.txt (deflated 7%)
.. and opening in the Finder correctly prompts me:
so there must be something wrong with your system.
Very Long Shot: What version do you get when you type this? (I can't imagine this is the actual problem, but you never know.)

I am trying to organize a zip file with a bunch of links and files. But when I drag an image file to a folder, it always "Snaps to grid" instead of just landing where I put it.

I am trying to organize a zip file with a bunch of links and files. But when I drag an image file to a folder, it always "Snaps to grid" instead of just landing where I put it. All of the files are going into the same zip file but I want them visually in the space that I put them and not at the bottom of the snap to grid folder location they are looking like. I am trying to drag and drop files in groups so that I can group them for now, but image files always do their own "sort by" when I drag them from my web pages. Links don't do it though. I tried resetting the folder, and deleting the DS files. No luck.

Tried~
The problem is still here~ >___<
Anyway, thanks for information sharing~
The message is:
Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again.
The problem may be here:
if (fos != null)
fos.close() ;
if (bos != null)
bos.close();
if (zos != null)
zos.close();
if (file != null)
file = null ;
The fos is closed before bos so the last buffer is not
saved.
zos.close() is enough.

What is the max size of a zip file with the JDK1.5 ?

Hello everybody,
I'm a french student and for a project, I need to create a zip file, but I don't know in advance the number and the size of files to include in my zip.
I wish to know if someone have the answer to my question : what is the max size of a zip file with the JDK1.5 ? I believe that with the JDK1.3, the limit size of a zip was about 2Go, wasn't ?
Thank you for all answer !
Good day !
PS : sorry for my very poor english ;-)

Here is all I have found for the moment :
...Okay, what about my suggestion of creating your own 10GB file?
Try this:import java.io.File;
import java.io.RandomAccessFile;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;
import java.util.Random;
class Main {
    public static void main(String[] args) {
        long start = System.currentTimeMillis();
        int mbs = 1024;
        writeFile("E:/Temp/data/1GB.dat", mbs);
        long end = System.currentTimeMillis();
        System.out.println("Done writing "+mbs+" MB's to disk in "+
                ((end-start)/1000)+" seconds.");
    private static void writeFile(String fileName, int numMegaBytes) {
        try {
            int numBytes = numMegaBytes*1024*1024;
            File file = new File(fileName);
            FileChannel rwChannel =
                    new RandomAccessFile(file, "rw").getChannel();
            ByteBuffer buffer = rwChannel.map(
                    FileChannel.MapMode.READ_WRITE, 0, numBytes);
            Random rand = new Random();
            for(int i = 1; i <= numMegaBytes; i++) {
                for(int j = 1; j <= 1024; j++) {
                    byte[] bytes = new byte[1024];
                    rand.nextBytes(bytes);
                    buffer.put(bytes);
            rwChannel.close();
        } catch(Exception e) {
            e.printStackTrace();
}On my machine it took me 43 seconds to create a 1GB file, so it shouldn't take too long to create your own 10GB. Then try zipping that file.
Good luck.

Decrypt Zip File with AES Cryptography

Hi,
I want to make a programm to decrypt a zip file with aes cryptography in java with gui.
Our professor as a help they gave us that code [http://code.google.com/p/winzipaes/source/browse/winzipaes/src/de/idyl/crypto/zip/AesZipFileDecrypter.java?r=4].
I search in Internet to find out same help for the project but I understood , that other programm don't use all the packages in the example.And i am little confused.
I want some help to find out a solution for this problem.And if you have a similar programm jusy sent it to occupy how I resolve my own problem.

As your professor has given you the crypto code and wants you to write the GUI code this is not a Cryptography question at all. Locking this thread.

Decrypt Zip File with 128bit AES

Hello my name is George ,

Finder crashed after downloading a zip file with pictures

First my desktop icons disappeared. Then the finder, appears and disappears every 3 seconds. Simultaneously the Finder also disappears and reappers in the "Force Quit Application" window. This started after I downloaded a zip file with family photos from a friend (on a windows machine). Rebooted off the Tiger installation dick. Running disk utility off the Tiger installation disk did not help. Permissions were repaired but the finder is still crashing Tried relaunching the Finder from the "Force Quit Application" window. No help. Ran Virex (outdated by 12 months) without any benefit.
Any suggestions would be appreciated.

There's a shameful glitch in Finder where if you drag certain attachments off a mail document onto the Desktop the Finder will do its quit/relaunch jitter bug--will also do it for illegally named files on the Desktop, and will hang for dang near forever it you accidently drop 100s of files onto the Desktop. The easy solution is to start the affected machine in target disk mode, hook it up by firewire to another Mac, then navigate to the affected user's Desktop folder and move the funky file or files into a new folder.

How to define new classpath of libraries while making jar files with ant

I am useing eclipse and ant and trying to make a jar file. I have used some external jar files. I have managed to add external jar files to my jar. But Still I have a problem. In my project all libraries in lib folder. But when I put them into jar file. They are in the root folder.Classpath has changed and It couldn't find the class path.
Is there any body knows how to define a new class path for external libraries with ANT. or How can I put my libraries into a lib folder in jar ?? I think both of them would solve my problem.
thanks in advance.
My code is like that, I think it requires a little modification
<target name="jar">
        <mkdir dir="build/jar"/>
        <jar destfile="build/jar/Deneme.jar" basedir="build/classes" >
            <manifest>
                <attribute name="Main-Class" value="${main-class}"/>
            </manifest>
             <fileset dir="${lib.dir}" includes="**/*.jar"/>
        </jar>
    </target>

Zip file with password using an applescript

Hi all;
I want zip a file with a password using an apple script. The problem is that I'll run the command
zip -ejr outfile infile
but how do I submit the password to the terminal?
I don't want the terminal to be visible during the process so I'm using this command:
tell application "Terminal" to do shell script sh
where sh is the command I want to run.
Thank you!

I'm running out of suggestions over here.
Your exact command line yields this result:

Problem downloading ZIP file with Squid-3.0

Hi,
I have upgraded my Linux CentOS squid proxy servers to Squid version 3.0. Since then I can not download the following file it just hangs :
http://download.oracle.com/otn/java/sqldeveloper/sqldeveloper-1.5.5.59.69.zip
I dont see any error in the squid logs or on my firewall.
I can however download it on one of the older servers still running Squid version 2.6.
It is just very strange as I can download ZIP files from any other website with the upgraded servers.
Any ideas on what might cause this ?
Thanks
JHEFER
Edited by: jhefer on Nov 19, 2009 12:15 AM

If you have already interested, I found the solution. The problem is that oracle website (and probably others) uses “Vary” field in the header and squid doesn’t support this (by default). You have to download squid sources on http://www.squid-cache.org/Versions/ and compile these with “--enable-http-violations” parameter :
*./configure ‘--enable-http-violations’ ‘…’ ‘…’*
make all
make install
I hope this solution will be very useful to you.

How can I create a zip file with LabVIEW?

I would like to compress my data (ASCII format) to an archive.
I use LVZlib.vi to compress and decompress data but I would like to be able to read the output file with a software archiver such as PowerArchiver/WinZIP.
Someone knows how I can create a file compatible with zip or gz standard format, thanks !

>> Yes but I have to install a special archiver (with ms-dos ommand line ability
>> such as pkzip,arc,rar,arj...) on the computer where I install my LV application.
Search for "gnu tools for windows" and get zip.exe, gzip.exe, bzip2.exe and others (even the source, if you like). These are about 50kB files that run in place (no installation) - easy to include in a distributed app. Oh, since I'm logged in I'll attach a couple, though I don't have the source on this machine).
