Applet and data base error. java.security.AccessControlException:

Hi All
I am new to java.
I am trying to access data base SQL 7.0 thru an applet but its giving an error "java.security.AccessControlException:"
Can any one help me plz!!!!
Thx in advance
Vipin

Is a Applet Application so, u have to sign the application using jarsigner tool
visit :
http://java.sun.com/j2se/1.3/docs/tooldocs/win32/jarsigner.html
http://java.sun.com/j2se/1.3/docs/tooldocs/win32/keytool.html
If NOT/before
Create a file name called ".java.policy" and placed/saved it in user home directory.
All the best

Amir,
You have to make your applet a signed applet.
Please search the Internet to find out how to do this.
Good Luck,
Avi.

Applet Error:java.security.AccessControlException: access denied

Hi,
I just successful deploy an business component project to oralce 8.1.6 as an EJB Session bean, and
the test of application module is successful. In the same workspace, I create an new project with
an applet(which contains only an grid control)as a client of the business component. Everything works
fine within the Applet viewer, however, when I trying to load the applet in IE5.5 I got the following

Hi Shaji,
Are you calling a webservice from within an Xacute Query for your applet? On first glance, it looks like a web service call is being rejected due to security permissions. If you have a webservice call (or HTTP post/get), can you test it separately with the same credentials as the webpage is using?

Signed applet not working in firefox - java.security.AccessControlException

Hello,
I have a signed applet that works fine in IE 7 but in Firefox I'm getting this exception in the java console:
java.security.AccessControlException: access denied (java.net.SocketPermission myhost.com resolve)
I already tried to run the applet with different JRE versions in Firefox with the same result: 1.6.0_01, 1.6.0_02, 1.6.0_03, 1.6.0_05
I'll appreciate your help.

thanx 4 replying
using the browser to view Applet is not recomended that is because if u change the the source-code and recompile the applet then run it using the broswer it will run the old-version
Also i've found the solution here

Hi,
I need a applet that check a flag in my database each "x" seconds...
Must I to use RMI for access the remote database, ok? How (if yes)?
If the flag is found then a "new MyFrameClient()" is open... This system is for instant communication for two active users in my site! First, a user click on link for invitation (then update fields in my database) and a "new MyFrameServer()" is open.

Java.security.AccessControlException when calling web service from applet

I have an applet that calls a webservce (Xmethods' delayed stock quote service). When I run the applet in appletviewer, I get the following:
[SOAPException: faultCode=SOAP-ENV:Client; msg=Error opening socket: java.security.AccessControlException: access denied (java.net.SocketPermission 66.28.98.121:9090 connect,resolve); targetException=java.lang.IllegalArgumentException:
Error opening socket: java.security.AccessControlException:
access denied
etc.....
My code works fine as an application, but not as an applet. (This was after I eventually had to extract the necessary SOAP .jar files into the same directory as my applet, but that's another topic...or maybe not?)
Help!
Regards,
John Kirksey

The default security settings does not give an applet to connect to any other server apart from the one from which it was downloaded. This is your problem. To mitigate that you have to change the security setting of the applet conatiner i.e the JVM in the browser.

Putting images in an applet - java.security.AccessControlException

So I made this Blackjack game using many many classes and a GUI and it worked fine. I then decided to put it online and turned it into an applet. This isn't my first applet that i've put online, so I know that I did all the syntax in the code right. On the other hand, this is the first applet i've put online that includes pictures. The game has a Card class with an ImageIcon variable for the image of the card. The problem is that the applet won't run in a browser, and I receive the follow exception:

"Back.png" refers to a picture of the back of the card. I have this picture, along with the other 52 card pictures uploaded to the website (i'm hosting on Netfirms). Please help me. I'm willing to share any necessary source code if the need arises.

You're trying to read the images off the local hard drive or from a server other than the one the applet came from.
That's normally not allowed.
Use Class.getResource and/or getResourceAsStream, and javax.imageio.ImageIO.read, to read the images. You specify the image paths as relative to the applet (e.g., don't start them with "C:\").

Java.security.AccessControlException: access denied; for a signed applet

Hi,
I have a signed applet which is used to read local files. When I call the applet method which is reading the file, from javascript I am getting "java.security.AccessControlException: access denied ". Where as if the method gets called during applet load, file is read without errors? How can I get over this problem?
If there is a way loading the applet based on a condition from Javascript, please let me know.
Thanks,

Java.security.AccessControlException: access denied when loading from a jar

Hello!
I am trying to deploy an applet into a browser but I have encountered a security problem.
The name of the applet is SWTInBrowser(not exactly mine, it's an example from the web).

import org.eclipse.swt.awt.SWT_AWT;
import java.applet.Applet;
import java.awt.event.ActionListener;

public class SWTInBrowser extends Applet implements Runnable{
 public void init () {
 /* Create Example AWT and Swing widgets */

 add(awtButton);
 awtButton.addActionListener(new ActionListener () {

 showStatus ("AWT Button Selected");
 javax.swing.JButton jButton = new javax.swing.JButton("Swing Button");
 add(jButton);
 jButton.addActionListener(new ActionListener () {
 public void actionPerformed (ActionEvent event) {
 showStatus ("Swing Button Selected");
 Thread swtUIThread = new Thread (this);
 swtUIThread.start ();
 public void run() {
 /* Create an SWT Composite from an AWT canvas to be the parent of the SWT
 widgets.
 * The AWT Canvas will be layed out by the Applet layout manager. The
 layout of the
 * SWT widgets is handled by the application (see below).
 Canvas awtParent = new Canvas();
 add(awtParent);
 Display display = new Display();
 Shell swtParent = SWT_AWT.new_Shell(display, awtParent);
// Display display = swtParent.getDisplay();
 swtParent.setLayout(new FillLayout());
 /* Create SWT widget */
 org.eclipse.swt.widgets.Button swtButton = new
 org.eclipse.swt.widgets.Button(swtParent, SWT.PUSH);
 swtButton.setText("SWT Button");
 swtButton.addListener(SWT.Selection, new Listener() {
 public void handleEvent(Event event){
 showStatus("SWT Button selected.");
 swtButton.addListener(SWT.Dispose, new Listener() {
 public void handleEvent(Event event){
 System.out.println("Button was disposed.");
 // Size AWT Panel so that it is big enough to hold the SWT widgets
 Point size = swtParent.computeSize (SWT.DEFAULT, SWT.DEFAULT);
 awtParent.setSize(size.x + 2, size.y + 2);
 // Need to invoke the AWT layout manager or AWT and Swing
 // widgets will not be visible
 validate();
 // The SWT widget(s) require an event loop
 while (!swtParent.isDisposed()) {

}It works perfectly in the Applet Viewer, but not in the browser. In the browser, I only get two buttons working, the SWT button doesn't appear, because of this error:

If you read the above trace from bottom to top, it shows none of you classes, only classes from that Eclipse library, which seems to loadLibrary() a native DLL. In order to do this, it needs to call System.getProperty( "sun.arch.data.model" ). This call is not allowed from un unsigned applet. So I guess you need to sign the applet and this problem will go away. Many other problems may follow. Just read very very carefully all the related documentation, which I did not.

HELP!!! java.security.AccessControlException: access denied

Please help!
I have the project to use the applet to show the form, this applet is needed to read the file from the server side. when i using the jbuilder to coding, it can work to use the appletviewer to run the program to read the file.
After that i placed the code to the webapp (localhost), when i start up tomcat and use the ie to view the http://localhost:8080/auditForm/AuditForm.html. (this AuditForm.html is embedded the test.class. test.class use to read the file.
but error was occurred.
i am using the File Object to read file

Hey guys,
You can access what ever file you want on the originating host i.e. the server.
Im guessing you guys are testing your applet code probably before it takes the form of an applet. It's fundamental to realise that applets are downloaded to the client and excuted in a 'sandbox' by the java-plugin installed in the client browser. Hence using a File instance pointing somewhere on the C:\ drive is totally pointless as you likely won't have permission to access the client's hard drive anyway. More to the point, it is totally wrong; the property files or movies do not reside on the client machine.... and there is no need to confuse matters by talking about signing Jars.
My advice is to read the Applet/JApplet APIs which cleary show how to access 'resources' on the server - no extra permissions are needed so it is not even a security issue. Also, you web application usually can not see outside its context/document base so you will need to put the property file or movies in the same directory (or a visible sub-directory) as the applet code/jar itself.
Hope this info is of some use.
Warm regards.

You posted a thousand lines of badly-formatted code and didn't have the sense to say which one had the exception.
My guess is that it was this one:Session session = Session.getDefaultInstance(props, null);because that happened to me. I fixed it by calling getInstance instead of getDefaultInstance.
However if that isn't the problem, how about spending a few seconds to post a less useless question?

Java.security.AccessControlException: access denied (java.util.PropertyPerm

Hi All,
I try to run an applet from Solaris 8 server on some client machine using IE5 and NetScape 6.2 ( I installed JRE 1.4, I also try other JRE versions) but I get the following errors again and agian,
I even try to use appletviewer on the Solaris Box itself to open the applet but it makes no difference same errors
could somebody please help or give me a hint how should I start tracing what the problem might be ?
this applet comes with Solaris Bandwidth Manager as a gui administration tool ( webbased ) it supposed to change the configurations remotly over the web. I asure there is no solaris permission problem exist.
I use Tomcat on the server side.Installed JDK 1.3 on Solaris 8 with all the default settings.
i suppose something should be done with java.policy or java.security files i know nothing about java security please at least give me some URL's to find out more about this matter i searched a lot but couldn't find good documents about java default security restrictions

I dont know, but It may be that an Applet can only access the local machine. ie. If you run the applet on computer A and you want to edit the config on computer B, I do not believe you can. The applet can only talk to Computer A. You would have to:
1) Run an application on computer A and the applet would tell the application what to change.
2)Maybe sign the applet in a JAR File
You will probably have to do #1.

Hi,
Please make changes in the java.security files present in the jdk1.3/lib/jre/security/java.security.There you make the changes in the property which gives you the error.See if this helps..

Re: java.security.AccessControlException: access denied (java.util.PropertyPermission weblogic.kernel.allowQueueThrottling read)

This looks like it might be a bug in 6.1SP5,
 weblogic/kernel/Kernel.java at line 85.
 It's trying to do the right thing to ignore an exception if in
 an applet but it's ignoring the wrong exception
 (SecurityException, when it looks like the stack
 trace is throwing a java.security.AccessControlException).
 If you need a fix, this would need to go through support
 and be filed as a problem with WLS Core.

I suggest going through customer support, I don't know what
 the resolution was. You might also try the security newsgroup,
 as no JMS code has been called by the application yet at
 the point the exception is thrown.

Java.security.AccessControlException when executing java from the DB

Hello
I'm running a Oracle 10.1.0.3.0 on Linux
I'm having trouble with executing some java code from the DB.
I created following java stored procedure used to create the directory given by the parameter
package be.vlaamsparlement.dis.os_commands;
import java.io.*;
import java.lang.*;
import java.sql.*;
import java.util.*;
public class ManageOSDirectory {
public static String createDir(String directoryName) throws Exception
if ((new File(directoryName)).mkdirs())
{ return ("TRUE");}
else
{ return ("FALSE");}
Wrapped it in a pl/sql procedure an execute it as follows under DB schema DIS :
begin
declare
b boolean;
begin
b := pck$os_commands.CreateDir('/data/files/vp_docs/schv/2004-2005/jan/1/');
end;
end;
Where /data/files/vp_docs/schv/ already exist, so the proc needs to create the direcories '2004-2005', 'jan' and '1'
this gives me following error :
ORA-29532: Java call terminated by uncaught Java exception: java.security.AccessControlException:
the Permission (java.io.FilePermission /data/files/vp_docs/schv/2004-2005/month/1 write) has not been granted to DIS.
The PL/SQL to grant this is dbms_java.grant_permission( 'DIS', 'SYS:java.io.FilePermission', '/data/files/vp_docs/schv/2004-2005/jan/1', 'write' )
I can't give this permission as the given directory does not yet exist. File permissions on os are ok and when i execute
the code on the os (not from the DB) it works fine.
This also worked on a Windows 10G DB without any extra grants.
Also, i can execute the followint
b := pck$os_commands.CreateDir('/data/files/vp_docs/schv/2004-2005/');
but if i then execute
b := pck$os_commands.CreateDir('/data/files/vp_docs/schv/2004-2005/jan/');
I get the same error. So i can only creaet 1 directory beneath the schv directory
Any ideas anyone ?

The Error message is right.
You need to:
Ensure the Directory exist in Unix.
Create the Directory in the Database as SYS.
Grant Read,Write permission on th DIrectory to DIS
Grant Java permission on th DIrectory to DIS (using the syntax already shown in the Error message).
See my example below (10g R1)
SQL> connect /as sysdba
Connected.
SQL> GRANT CONNECT,RESOURCE TO DIS IDENTIFIED BY DIS;
Grant succeeded.
SQL> create or replace directory DIS_DOWNLOAD_DIR as '/data/files/vp_docs/schv/2004-2005/month/1';
Directory created.
SQL> col DIRECTORY_PATH format a50
SQL> select * from dba_directories;

SQL> GRANT READ,WRITE ON DIRECTORY "SYS"."DIS_DOWNLOAD_DIR" TO "DIS";
Grant succeeded.
SQL> EXECUTE DBMS_JAVA.GRANT_PERMISSION( 'DIS', 'SYS:java.io.FilePermission', '/data/files/vp_docs/schv/2004-2005/jan/1', 'write' )
