ExceptionInitializerError caused by java.security.AccessControlException
We are getting an Exception condition on Solaris 10 (08/07) that does not occur on Suse Linux Enterprise Server or a Red Hat Server. It occurs in both a servlet or a Session Bean from the Java Application Server 8.2 Platform Edition. We are using JavaPOS to access a receipt printer from a servlet or from a Session Bean. The error occurs when the printer driver attempts to open a port to a network printer. The exception at the top of the message stack in the Application Server log file is ExceptionInitializerError at jpos.BaseJposControl.open(Unkown Source) and later in the stack there is a message "Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write)". We have the source code for JavaPOS and have begun to walk through it to discover the problem. However, this is the same *.ear file that is running on SLES and also Red Hat without the exception and has done so for several months. I got to ask what is the difference with Solaris 10. We have tried several different additions to the java.policy file in the jre/lib/security directory but it is basically the same file as used with SLES and Red Hat.
I have hammered on this problem for several hours and would appreciate any suggestions or more experienced insight into this problem.
One more point. The receipt printer can be accessed and used if the code is in a Desktop Application on the Solaris 10 system. The problem only occurs when the Application Server is involved.

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

mehmadI 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.

mehmadHi,
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..

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).
package my.applet;
import org.eclipse.swt.awt.SWT_AWT;
import java.applet.Applet;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import java.awt.Canvas;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Listener;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.layout.FillLayout;
public class SWTInBrowser extends Applet implements Runnable{
public void init () {
/* Create Example AWT and Swing widgets */
java.awt.Button awtButton = new java.awt.Button("AWT Button");
add(awtButton);
awtButton.addActionListener(new ActionListener () {
public void actionPerformed (ActionEvent event) {
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()) {
if (!display.readAndDispatch()) display.sleep ();
}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. -

The strange thing is that I can connect to my server if I run the client on
NT4 !!!
I solved the problem by modifying my local java.policy file with the
following settings:
// Test with HTTP tunnelling. 18.10.2001
[email protected]
permission java.util.PropertyPermission "proxyHost", "read";
permission java.util.PropertyPermission "proxyPort", "read";
permission java.util.PropertyPermission "http.proxyHost", "read";
permission java.util.PropertyPermission "http.proxyPort", "read";
permission java.net.SocketPermission "*","connect,resolve";
// Test with HTTP tunnelling. 18.10.2001
[email protected]
Have someone else experienced the same or similar problems ?
How can I make sure that the client gets access to read the properties
http.proxyHost, http.proxyPort, proxyHost and proxyPort without telling the
users of the client application to modify their java.policy files ?
Any leads will be greatly appreciated !

Anybody has experienced this before? Workaround?
Thanks.I think I figured this out. Since I installed the TP4, I used this for developing other apps without WC enabled. I noticed that when I started JDev for the first time, it creates the embedded server (?) in a directory you specified in JDEV_USER_DIR env var automatically. When I changed my TP4 to use WC, the required libraries, etc. were not copied or built for WC. I think this caused the problem I had. By closing JDev and deleting the created embedded server and restarting JDev, it solved my problem.
For TP4, the server directory looks like:
system11.1.1.0.22.49.49
I hope this will be useful for others that experience the same problem that I had. -
Applet Error:java.security.AccessControlException: access denied

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

fine within the Applet viewer, however, when I trying to load the applet in IE5.5 I got the following

ERicHi 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?

How can i deal with java.security.AccessControlException?
Hi all, I need to implement JavaMail using Servlet and deploy throught J2EE deployment tool. But when i test out the servlet i will always encounter this exception thrown. How can i solve this?
java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write)
This is the servlet i am testing. Please advise. Thanks in advance!

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.

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 KirkseyThe 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.

i signed my applet like

jarsigner TestApp.jar sgsitshave we to modify polacy file also?
if so how & which one modify
any suggestion would be greatly appreciated
thanks in advanceI assume your signature is correct.
Signing the applet enables privileges (like file IO) whenever all the calls on the stack leading
to the sensitive operation (in your case fis = new FileInputStream("c://premji.rar")) originate
from the signed jar. It is not your case, as you come into the applet from javascript.
The solution is to use AccessController.doPrivileged...(). It was designed with this situation in mind. -

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

thx in advanceYou're running the server with a SecurityManager. There's no need to do that at first. Get rid of it. When you have it working, write yourself a .policy file that grants that permission, and any others you discover it needs, and name that as your security policy file, e.g.
java -Djava.security.policy=my.policy -Djava.security.manager mypackage.MyServer ... -
Can't fix a java.security.AccessControlException exception
Hi.
I have a webapp running under j2ee with a ContextListener that performs some initialization tasks.
One of these tasks consists in querying a database and putting the results in a xml file according to an existing xml file that acts as a map for it maps the rows and columns of the result set to elements and attributes in the xml doc (this task is really performed by an EJB that the ContextListener instantiates).
To do this, at some point the EJB tries to instantiate a new org.w3c.dom.Document object pointing to the xml map file witch, like I said, will be used to 'massaje' the data in the query into a xml format.
Here's the revelant portion of the code:
mapDoc = docbuilder.parse(mapfilepath);
When the EJB tries to do this, the following exception is thrown:
java.security.AccessControlException: access denied (java.io.FilePermission c:\j2sdkee1.3.1\public_html\iFAQs\xml\temas-map.xml read)
I've checked the server.policy file and it seems ok, it has a grant section that makes me believe I should have read and write access to all files under public_html:
grant codeBase "file:${com.sun.enterprise.home}/public_html/-" {
permission java.lang.RuntimePermission "loadLibrary.*";
permission java.lang.RuntimePermission "accessClassInPackage.*";
permission java.lang.RuntimePermission "createClassLoader";
permission java.lang.RuntimePermission "queuePrintJob";
permission java.lang.RuntimePermission "modifyThreadGroup";
permission java.io.FilePermission "<<ALL FILES>>", "read,write";
Any help will be much appreciated!
Thanks!
Best regards,
Piponline, Portugalhi piponline,
