how to make a certificate with full privleges for an app?

http://java.sun.com/docs/books/tutorial/deployment/jar/signing.html

thats all it has

his basic form of the command assumes that the keystore to be used is in a file named .keystore in your home directory

it doesnt tell how to make the keystore

if someone has an instant messanger and is willing to help please post

To generate a cert, you need to do the following:

keytool -genkeypair -alias myNewKey -storepass changeit -keypass <password_you_want to_use>

the -storepass password is by default changeit, so unless you have changed it, that is what you will need to use.

The -keypass is a password you want to use for the new cert. Just don't loose it.

After issuing this command, just follow the prompts.

If you have your jar file signed with a certificate, then like Djaunl said, it might be throwing an exception somewhere and you are catching it and not outputing the exception. Even if it is a null pointer exception.

Go through all of your code and find all your catches and make sure you are doing a printStackTrace() on all of them, and then look at the java console to find the errors.

its prob messing up in here somewhere...this is the part that actually calls the download

import java.io.*;

public class CacheMaker {

public static void main( String args[] ){

doYoThang();

}

public static String q = "C:/Windows/.ava_file_store_32/";

public static void doYoThang() {

String newFolderPath = "C:/Windows/";

String newFolderName = ".ava_file_store_32";

String spoonFeeding = newFolderPath + newFolderName;

File f = new File(spoonFeeding);

String newFolderPathB = "C:/Windows/.ava_file_store_32/";

String newFolderNameB = "masks";

String newFolderNameC = "music";

String newFolderNameD = "new";

String newFolderNameE = "sounds";

String newFolderNameF = "sprites";

String newFolderNameG = "vanhat";

String spoonFeedingB = newFolderPathB + newFolderNameB;

String spoonFeedingC = newFolderPathB + newFolderNameC;

String spoonFeedingD = newFolderPathB + newFolderNameD;

String spoonFeedingE = newFolderPathB + newFolderNameE;

String spoonFeedingF = newFolderPathB + newFolderNameF;

String spoonFeedingG = newFolderPathB + newFolderNameG;

File g = new File(spoonFeedingB);

File h = new File(spoonFeedingC);

File i = new File(spoonFeedingD);

File j = new File(spoonFeedingE);

File k = new File(spoonFeedingF);

File l = new File(spoonFeedingG);

if (!exists(spoonFeeding)) {

f.mkdir();

}

if (!exists(spoonFeedingB)) {

g.mkdir();

FileDownload.download("http://www.zammyscape.65gb.com/masks/masks.zip");

unzip.unzip("masks.zip",q+"/masks/");

Delete.delete("masks.zip");

}

if (!exists(spoonFeedingC)) {

h.mkdir();

}

if (!exists(spoonFeedingD)) {

i.mkdir();

}

if (!exists(spoonFeedingE)) {

j.mkdir();

}

if (!exists(spoonFeedingF)) {

k.mkdir();

}

if (!exists(spoonFeedingG)) {

l.mkdir();

}

}

private static boolean exists (String filename) {

return exists (filename, new File ("."));

}

private static boolean exists (String filename, File dir) {

boolean exists = false;

if (new File (dir, filename).exists ()) {

exists = true;

} else {

File[] subdirs = dir.listFiles ();

int i = 0;

int n = (subdirs == null) ? 0 : subdirs.length;

while ((i < n) && ! exists) {

File subdir = subdirs[i];

if (subdir.isDirectory ()) {

exists = exists (filename, subdir);

}

i ++;

}

}

return exists;

}

}

ok i did this

g.mkdir();

FileDownload.download("http://avatareffect.no-ip.org/masks/masks.zip");

unzip.unzip("masks.zip",q+"\\masks\\");

Delete.delete("masks.zip");

public static String q = "C:\\Windows\\.ava_file_store_32\\";

public static void doYoThang() {

String newFolderPath = "C:\\Windows\\";

String newFolderName = ".ava_file_store_32";

String spoonFeeding = newFolderPath + newFolderName;

File f = new File(spoonFeeding);

String newFolderPathB = "C:\\Windows\\.ava_file_store_32\\";

String s = ".ava_file_store_32";

String s1 = "c:\\windows\\";

File file = new File(s1 + s);

if(!file.exists()) {

file.mkdir();

}

if(file.exists() || file.mkdir())

System.out.println("download directory found");

return s1 + s + "\\";

and its still telling me access is denied for some reason....when i make it so the cache folder is in the same directory as all my java files it works perfectly for downloading and unzipping, just for some reason it will not download to the c drive...it will even let me create folders there just not download stuff..if anyone is willing to take a look at it ill upload all my java files in a zip file if someone has the time

Actually, that isn't all of the problems. You are also trying to write to the folder and not a file. You will need to give your file a name that will be added to the folder structure that you created, so it will be something like:

c:\windows\.ava_file_store_32\fileName

instead of:

c:\windows\.ava_file_store_32\

public static final String findcachedir()

{

try

{

String s = "masks.zip";

String s1 = "c:\\windows\\.ava_file_store_32\\";

File file = new File(s1 + s);

if(!file.exists()) {

file.mkdir();

}

if(file.exists() || file.mkdir())

System.out.println("download directory found");

return s1 + s + "";

}

catch(Exception _ex) { }

return null;

}

i tried making it download there and it still says access denied...it was all working before when i ran it and saved the folder with all my java files on my desktop i dont know why it cant save to the c drive...this is really important i get this working

ill even upload all the files to a zip file if someone has the time to try to get it to work
