Grant permissions dynamically in a applet

I am try to write a java applet and wants it can the access the local disk...
I know one way is modify the Security policy files in the JRE ( this method can support signed or unsigned applet ), but this need user manually modification before run the applet.
Can any method support grant permissions dynamically in java applet.
e.g
prompt a dialog to ask the user do they allow the applet grant the permissions

Just try to sign your applet , it's easy to do . if you want to know the process of how to sign your applet , i can give you some advise , my email address is :[email protected] . Best wishes !

Problem of granting permissions for a signed applet

I'm writing an applet, which needs to
1. write a file into client file system, then
2. launch an application to edit this file, then
3. read the edited content from the file
Obviously, all the above 3 steps are restricted operations, they are not allowed for an applet by default. So I suppose that if the applet is signed, it will get the additional permissions. And because I want this applet work for both IE and NS browser, I choose to use Java Plug-in.
But base on the Java 2 Security Tutorial, it seems I can't specify the permissions in the jar. I can only sign my applet, let the end user knows this applet comes from me. And it's the end user's job to run the policytool program, and give the "FilePermission" of "read, write, delete, execute" to the code signed by me(or download from a specific codebase, or both), if they decide to "trust" me.
I can't imagine how to make the business user understand the Security concept of Java, and ask them to configure their system properly. It's just a mission impossible! So, did I miss some important part in the signning process? Is there such a way which keeps the policy setting for this applet in the signed jar, so the business user only need to click "Grant" to allow it running?
Thank you very much.
Kevin Zhang
P.S. some interesting facts confuse me:
1. I signed the jar (which I'm not sure if I signed it currectly, I will tell you why later), and converted the <applet> tag to <object> tag for IE. It works, which makes me confused :-) Because I didn't specify the permissions at all, neither in the code nor in the signning process. Should I consider that by default it gives all the permissions?
2. Same jar file. I use the original <applet> tag on Netscape 6.2, which use java plug-in to handle <applet> tags. This time an AccessControlException is thrown. I can understand that's obviously because of no permission. But both this one and the above one are using same JRE 1.3.1_01 plug-in, why they behave differently?

Hi Kevin
I have the exactly the same requirement as yours....
(1. write a file into client file system, then
2. launch an application to edit this file, then
3. read the edited content from the file).
Plz go thru the following. I signed my applet as follows:-
makecert -sk exec -n "CN=Hemanth" exec.cer
cert2spc exec.cer exec.spc
javac ExecNP.java (ExecNP.java is the applet code. I have given the code of the applet)
cabarc -s 6144 n exec.cab ExecNP.class
setreg 1 true
signcode -j javasign.dll -jp exec.ini -spc exec.spc -k exec exec.cab
chkjava exec.cab
Code of ExecNP.java :-
import com.ms.security.*;
import com.ms.security.permissions.*;
import java.lang.Runtime.*;
public class ExecNP extends java.applet.Applet
public void init()
     try {
          PolicyEngine.assertPermission(PermissionID.EXEC);
          Runtime.getRuntime().exec("c:\\windows\\notepad.exe");
     } catch(Exception e) {
Here is the html code :-
<applet code=ExecNP width=800 height=200> <PARAM NAME='cabbase' VALUE='exec.cab'> </applet>
When I try to open this html file I get the following exception in the Java Console
java.lang.UnsatisfiedLinkError: initPolicyEngine
Please tell me whats wrong.
Hemanth.

No Grant Permissions Dialog Showing

Hey guys, I am trying to write a simple applet that executes a file on the users local filesystem. I have signed the applet by first creating a keystore and then using jarsigner to self-sign the applet. However, when the applet is executed it throws an AccessControlException when trying to execute the file (a FilePermission error on the execute)
The applet is compiled in 1.5.0_09 and run in the 1.5.0_09 JRE. I have tried running the applet from an HTML page both locally through the filesystem and remotely through my webserver on 2 separate machines.
The problem is, it just throws an exception and doesn't even ask the user to grant it permissions which I imagine is what I need to do
Here is the code:
package Jim;
import java.awt.*;
import java.applet.*;
import java.io.*;
import java.util.*;
import java.security.*;
import netscape.javascript.*;
public class WinampConnect2 extends Applet {
     private String msg;
     public void init()
                           GetWinampInfo();
     public void paint(Graphics g) {
          g.drawString("MSG: " + this.msg, 50, 60 );
     public void GetWinampInfo()
          String msg2 = (String) AccessController.doPrivileged(new PrivilegedAction()
            public Object run()
                   try
                        FilePermission MyPerm = new java.io.FilePermission( "c:\\WinampMagic.exe", "execute" );
                        Runtime runtime = Runtime.getRuntime();
                        Process process = null;
                        process = runtime.exec("c:\\WinampMagic.exe");
                          DataInputStream in = new DataInputStream(process.getInputStream());
                          // Read and print the output
                          String line = null;
                          return in.readLine();
                   catch (Exception e)
                        System.out.print(e);
                        System.out.flush();
                        return "error";
          this.msg = msg2;
}If anyone could offer me any advice on what I am doing wrong or how to correct this I would be very appreciative. Thanks in advance guys.
Jim.

Thanks for the input but that seems a bit of a cop-out. I realise that Applets are by default limited in their abilities which is why there is the ability to sign them in the first place.
I know permissions aren't a problem as other applets I have tried which request permissions pop up the grant permissions dialog which my applet does not.
I need this applet to run from a webpage and communicate with the DOM/Javascript on the page from my website for an experiment I am working on. I have worked with applets before and not had this problem with security so am wondering if there is something wrong with my code or a known bug that I am encountering.
Please don't get me wrong, Lion-O, I appreciate your response, I just would really like to learn from this problem by fixing it rather than giving in.
Can anyone else help?

What are the default permissions for "self-signed" applets?

Hello!
I have a self-signed applet (=signed with a self made certificate) and under most plugin-enviroments java asks the user if it accepts this certificate as trustworth.
On my linux-box I do not have any problems to write files to the local filesystem after I accepted this self-signed applet.
However I've often read that users must grant some permissions even for signed applets, so is there a list of permissions that are denied by default?
Are there differences between java releases starting with 1.2.2?
Thanks in advance, lg Clemens

Default settings are like you said, jre asks the user and everything will work.
Unless.your applet uses classes that are not signed like with calls from javascript to your applet the plugin.jar is used and you'll get an exception when writing to files.
When writing to files the OS might not allowe the user to write to a certain file or folder.
Don't know what type of exception will be thrown if the OS doesn't allowe it but it has
nothing to do with applet permissions.
To change the default setting you can add the following line in the grant { bit of the
java.policy
permission java.lang.RuntimePermission "usePolicy";
When this line is there all signatures will be ignored and an applet can only do extra
things (like access to local files) if a policy is set up for this applet.
To find out what's wrong at your clients site you should ask them to send a full trace
and check that. I hope you did a .printStacktrace() on the exception in your code so
you can see if any other classes are involved when the exception is thrown.
To turn the full trace on (windows) you can start the java console, to be found here:
C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
In the advanced tab you can fill in something for runtime parameters fill in this:
-Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
if you cannot start the java console check here:
C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
I think for linux this is somewhere in youruserdir/java (hidden directory)
add or change the following line:
javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
for 1.5:
deployment.javapi.jre.1.5.0.args=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
The trace is here:
C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
I think for linux this is somewhere in youruserdir/java (hidden directory)

Assign file permissions dynamically through FTP adapter

In my composite, i have a requirement to assign the file permissions dynamically.
I know the static way of doing it is to use the property 'Permission' in the jca file of the ftp adapter.
Is there any way to pass the value to this property dynamically?
I tried using jca.ftp.Permission. but not working.
Any help on this is much appreciated.
Thanks,
Naveen Kumar T.

Hi,
The document with the properties is this... It doesn't mention any properties for permissions though...

Problem with granting permissions in the security policy file

Hi,
I have a security policy file. I am granting permissions to some files. Now even if I have given permissions explicitly it doesnt taking it and gives error. My code snippet is as follows:

Any clues?!

Need urgent help on dynamic download of applets in smart card

hi
Can anyone help me on dynamic download of applets onto smartcard using javacard kit.
I need to know : 1. how much memory it requires?
2. how fast it is?
3. the limitations?
Regards
Bharath

Hi Joseph,
I wanted to know the minimum memory requirements / constraints (if any). The size of the smallest capplet I have is around 10K . I dont want any extra features on the install method as of now. I am still not clear how to take up the scriptgen path of dynamic applet downloading. Can you please elaborate some initial steps to start with? I have already gone through the JCDK users guide, HC12 users guide and CW manuals. I have also successfully flashed and tested JCDK on HC12 for maskgen path.

Grant permission for a signed applet

I have my jar file signed. Now, I hate to have the user to modify their .java.policy file, beside, I did not have my certificate verified by Verisign. Is there any other way to do it? I have read some posts which the user of the signed applet will see a pop up dialog while loading the signed applet, if they click on "grant all access", then the applet will have all the permission. Can anyone tell me how to do that?
Thanks
Andy

nicoleman1 put together a "tutorial" on signing your applet (jar). The instructions will work for all browsers that support the Java Plugin.

ERROR: policy does not allow granting permissions at this level outlook

Hi All,
Our users are attempting to send sharing requests to each other via Right Click Calendar | Share | Share Calendar
Availabilty only works fine but Limited and Full Access fails with the error: policy does not allow granting permissions at this level.
I can see that the default sharing policy is set for availabilty only so I assume I need to add our internal SMTP addresses to the sharing policy with increased right's.
But... From our testing in our LAB we found that if the exchange org does not have a connection to the federation setup it works fine straigh out of the box.
Does this sound right or is my LAB just messing with me?

SP2013 Form to populate a list without granting permissions

Hey All,
I have someone who wants a way to populate specific fields in a list, without granting permissions to the site or list. I don't think it can be done, but I figured I would check with everyone anyways. Is it possible?
Thanks for the help!

You are right. without permission it is not possible.
Please 'propose as answer' if it helped you, also 'vote helpful' if you like this reply.

Granting permissions for JAVA STORED PROCS

If I imported a java class file as user test and created a stored proc, how can I grant permissions to all the users in the DB? Do I have to grant permissions on JAVA CLASS itself when I load it or Do I have to grant permissions on the Stored proc or Both?
Any help will be greatly appreciated.

Note: I can manually add the file with the command -
loadjava -v -user user/password@sid sqljdbc.jar (pg 261 in Oracle Database Programming using Java and Web Services by Kuassi Mensah)
Which is what I have done to get this to work. But the question still stands - How do I get the sqljdbc.jar file to be loaded when deployed using the deployment descriptor?

Removing and granting permissions - can item.systemupdate(false) be used

Hi,
When removing and granting permissions programmatically, can the item.systemupdate(false) be used?
I have used the below code for removing permissions. Is this systemupdate(false) the right thing to use or item.update?
oSPWeb.AllowUnsafeUpdates = true;
CurrentlistItem.BreakRoleInheritance(false);
oSPWeb.AllowUnsafeUpdates = true;
using (DisabledItemEventsScope scope = new DisabledItemEventsScope())
CurrentlistItem.SystemUpdate(false);
//or is it better to use - CurrentlistItem.Update();
Thanks

you should not need the DisabledItemEventsScope.
You do not need to use SsytemUpdate.
You *probably* don't even need to use AllowUnsafeUpdates.
just BreakRoleInheritance and then Update.

Hi Manuk
In Grant Permissions block, two methods are provided for you to choose when granting permission to others. One is a drop-down list for you to add users into, the groups in the list are the groups in Site settings > people and groups. Another is to for you
to grant permissions directly, it explains permission concept with actions could be done. Two methods are nearly the same.

Problem in Granting permissions for Signed Applet

Hi,
I have signed my applet with my self generated certificate. The client browser has imported this certificate in his cacerts keystore as trustcacerts. When I grant permission for my client(manually,in the client machine), I have peculiar errors.
Case 1 : grant codeBase "http://***.XXX.***.XX/-" { permission java.security.AllPermission; };
This permission works fine. But the client is able to download all applets from the granted machine, including unsigned applets.
Case 2: grant SignedBy "dcard" codeBase "http://***.XXX.***.XX/-" { permission java.security.AllPermission; };
If I add the signedBy tag, this particular grant section is completely omitted by the system. That is, the browsers does not recognize the signedBy tag( & its entire grant block) and throws SecurityExceptions for accessing the local machine.
Please help me to grant permission for the applet coming from a particular source AND signed by a particulr person.
Thanks in advance,
Rajesh
Note : Plug-in is java1.3.0_02. The public certificate is imported as trustcacerts in all cacerts files in system.
