HAL policy file to change DPI

I have Acer Aspire One... X works pretty much out of the box without xorg.conf file. Problem is that HAL doesn't seem to detect the DPI correctly... could someone please post the correct policy file to make fonts smaller?

Have you tried editting your startx file?
vim /usr/bin/startx
Find the line that says:
defaultserverargs=""
and add your dpi like this:
defaultserverargs="-dpi 96"

How can I change the policy file?

I have designed an applet to read a file from the local Machine.
This applet thro a servlet reads the contents of the file specified.
I use Tomcat 4.1.12 server and this is an client-server application.
To read the file in the local machine, I set the permission as follows in the .java.policy file in the Local Machine.
grant codeBase "http://MyMachine:8080/Example" {
permission java.io.FilePermission "<<ALL FILES>>", "read, write, delete, execute";
as the applet file is in the Example of the server "MyMachine".
Its working and my applet is able to read the file from the local machine it runs.
Now my problem is I cannot set/change the policy file in every machine where my applet runs.
Instead if there is a way to change the policy when the applet downloads,that'll be effective.
That is I donot want to go and change the policy file manually in each and every machine where my applet runs(I donot even know which are the machines going to run the applet).
Is there any means to acheieve my need?
Please explain me in detail or direct me to the relevent web sites or links.
Thank you

Hi Hosuke,
I had the same problem, thanks for the advise.
Still I have a remark to make.
The thing is that, in order for the applet to have the permission granted (for whatever), you need to have a policy file which you can include in the JAR file (like you explained before) AND also you need to add an entry in the java.security file (located for me: "C:\Program Files\Java\j2re1.4.1_01\lib\security\java.security") that tells the applet where to find all the .policy files.
Something like: policy.url.4=file:/c:/java.policy
But since we are talking about an applet we are not able to make changes to this file.
Maybe you or anyone else knows a workaround for this problem.
Thanks in advance,
Ronald Vromans.

Dynamically change the JAAS auth policy file

We want to honor the JAAS auth policy file change while the java process is still running. Currently, if you change the permissions in the JAAS auth policy file after the java process is launched, the changes are not picked up by the security manager. Is there a way to honor the permission changes without re-launch the java process?
Thank you very much!
JST

Hey,
No you do not call policy.refresh() at this time; you call it when the underlying policy file which supports the default implementation is changed - otherwise what are you refreshing.
Perhaps consider implementing a database backed policy; I can't help feeling it would be a less troublesome method if you need a certain level of dynamism in you policy entries.
Warm regards,
D

Java.policy file - Must I change it?

I just got a certificate from Verisign with which I signed my applet. It works fine and now I want to distribute it to a group of users.
Back when I was developing the applet with a self-signed cert, I changed the java.policy file to allow the applet to do things 'outside the sandbox'.
I thought, perhaps mistakenly, that when I got the Verisign ceritifcate I would not need to concern myself with java.policy in any way. But now, even with the Verisign cert, my applet won't run correctly w/o the updated policy file.
This is only important to me as I do not want to go around to 'x' number of user workstations and modify each java.policy file.
Am I missing something??
thanks

You mention
"you should be able to remove the policy file and users can just accept the certificate "
I experience the same, remove all policy files, signed applets can then access resopurces on the local machine. However, practically all the documentation I read regarding JAVA 2 (I'm using 1.4.1_02) says you must have a policy file when using a signed applet. At least they say sign your applet and then indicate what the policy file should look like to grant specific permissions for that applet. I find no policy file will still allow a signed applet to access local files... Is this a bug in JAVA 2 1.4.1_02, or the correct behavior. thanks in advance.

Hi, i changed policy file.. still this exception but file wrote plz...plz..

Server.policy file

The ejb I am developing is trying to delete the following file from a local filesystem (Linux SuSE 9.3 Pro) : /path/to/file/delete.me I get the following exception:
java.security.AccessControlException: access denied (java.io.FilePermission /path/to/file/delete.me delete)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)

at java.lang.SecurityManager.checkDelete(SecurityManager.java:990)
at java.io.File.delete(File.java:869)
I tried to modify the server.policy file adding the following line:
permission java.io.FilePermission "/path/to/file/delete.me", "delete";
but nothing changes, even when I restart the application server (don't know even if it is necessary to restart). I am using Sun Java System Application Server Enterprise Edition 8.1. Any help is welcome...
Thanks in advance

I think I solved the problem. At least I managed to delete the file :-)
First I had to add the following line to JRE's java.policy file:
permission java.io.FilePermission "/path/to/file/delete.me", "delete";Then I added the following entry to the server's server.policy file:
grant codeBase "file:${com.sun.aas.instanceRoot}/applications/j2ee-apps/MyApp-" {
permission java.io.FilePermission "/path/to/file/delete.me", "delete";
};like described here:

XMLSocket "Failed to load policy file" error

I am trying to use an XMLSocket.swf file, and it is not connecting. Do I need to open up a port on my server? I am trying to run this on a dedicated remote Windows 2008 server.
Here is the error from FlashFirebug:
     OK: Root-level SWF loaded: file:///C|/Users/vcaadmin/AppData/Roaming/Mozilla/Firefox/Profiles/70vbx4ys.default/exten sions/flashfirebug%40o%2Dminds.com/chrome/content/flashfirebug.swf

    Error: Request for resource at xmlsocket://speak-tome.com:9997 by requestor from http://speak-tome.com/flash/XMLSocket.swf has failed because the server cannot be reached.
My crossdomain.xml is saved to the root of the web directory and looks like:
    <?xml version="1.0"?>
    <!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">

    <allow-access-from domain="*"/>
    <allow-http-request-headers-from domain="*" headers="SOAPAction"/>
    </cross-domain-policy>
I notice that both ports 843 and 9997 are closed for my domain (speak-tome.com - 72.167.253.16) when I check using a service such as yougetsignal.com/tools/open-ports. Do I need to get these ports open to get the policy file to work?

As a test, I uploaded my Flash/Gaia site into an existing site on my old host. And although the site actually works in this setting, when I run things in the FlashPlayerDebugger, I'm still getting Security Sandbox Violations - so (as adninjastrator suggested in earlier post), this may have nothing to do with the DNS changes - but perhaps with my setting things up wrong somewhere so that the Flashplayer is trying to access my local computer - maybe??
Debugger logs gives me this:
Error: Failed to load policy file from xmlsocket://127.0.0.1:5800
Error: Request for resource at xmlsocket://127.0.0.1:5800 by requestor from http://recreationofthegods.com/bin/main.swf has failed because the server cannot be reached.
*** Security Sandbox Violation ***
So, I've now uploaded the identical bin (which contains all the files for my site) - but I'm getting different behaviors on the two hosts.
On the new holistic servers, the site won't go past the first page: www.yourgods.com
On the 1&1 servers, I still get runtime errors in FlashPlayerDebugger - but the site runs ok - http://www.RecreationOfTheGods.com/bin/index.html
Posting those links in hopes someone with more experience in these sandbox issues can help steer me in the right direction.

I know this is a relatively old post, but some people can stumble on this page when doing a search for this problem.
Anyway, I ran into this on my PC after I installed Sybase which had an older jre.
Solution:
1. Run regedit
2. Look for Java Runtime Environment
You may have to do multiple searches. Eventually you'll find one with the version number.
3. Modify the value and change it to the correct version number. (in your case, you would have changed it from 1.4 to 1.6).
This is much quicker than reinstalling Java every time installing something that uses an older version of Java hoses up the registry value.

File Access with unsigned Applet through editing the java.policy file

I'am starting to lose my hair on this...
I am trying to get an applet to run so that it can access the file system to move files on my local maschin. Because this applet is only running on my VM i can change the java.policy to avoid the signing of the applet.
first of all, if i wrote in the java.policy file
grant {
permission java.security.AllPermission;
};everything is working perfekt.
But I have not the intention to open the gates for any applet out there, so i want to limit the access to my applet. With every of the following versions I get at best an
java.security.AccessControlException: access denied (java.io.FilePermission...
My Setup
My Java Version: jre1.6.0_02
My applet is located unter the url
http://admin.mydomain.com/applet.jar
In Html i tryed the following different versions of loading the applet - none worked
<applet codebase="http://admin.mydomain.com/" name="shortcut" code="start.class" archive="applet.jar" width="0" height="0"></applet>
<applet codebase="http://admin.mydomain.com" name="shortcut" code="start.class" archive="applet.jar" width="0" height="0"></applet>
<applet name="shortcut" code="start.class" archive="http://admin.mydomain.com/applet.jar" width="0" height="0"></applet>in java.policy i tryed following versions with every html applet load version
grant codeBase "http://admin.x-press.de/-" {
permission java.security.AllPermission;
grant codeBase "http://admin.x-press.de/+" {
permission java.security.AllPermission;
grant codeBase "http://admin.x-press.de/applet.jar" {
permission java.security.AllPermission;
};why is it with
grant {
permission java.security.AllPermission;
};working, and not with the other versions?
i am almost bold now, please try to save my last hair from falling down.
any suggestion would be nice
thanks, feyyaz

I read the mentioned documentation and your right, some of my versions were wrong, but after reading the doumentation again i came to following result which should had worked but didn't.
java.policy
grant codeBase "http://admin.mydomain.com/*" {
permission java.security.AllPermission;
HTML File
<applet codebase="http://admin.mydomain.com/" name="shortcut" code="start.class" archive="applet.jar" height="0" width="0"></applet>if I am entering http://admin.mydomain.com/applet.jar i can download the jar, so the archive lays in the correct directory.
what i am doing wrong? do i have to change an additional file somewhere else?

JCE: jurisdiction policy files

Hello, I am new to this forum and my English is not very well. I have the following problem. I wish to use unlimited cryptography within an applet. I know, if I want to use unlimited crypto I have to install the unlimited jurisdiction policy files. Because mostly the JRE is installed under c:\programm files, where a normal user would not have the right to write, it is not very convenient to ask an admin for every workstation to install the unlimited jurisdiction policy files. Is there anyway to use unlimited crypto without touching the clients JRE?!?!
Is it possible to install the unlimited jurisdiction policy files in another location on client at runtime???
Maybe I can use an alternate JCE (BC or GNU)? But how? I think I can not install a new javax.crypto* from an applet? Maybe it�s possible to user another packet name?
Or is it possible to use the cipher functionality of a provider outside the JCE?
Have somebody had the same problem before? Any answer is very welcome!
Regards from Berlin!

If it could be done, it would be a serious security bug. Normal users cannot remove or change that file at all under Windows, only power users or admins can do that. An applet can have access to a file, but only if it gets permission to do so (e.g. by being signed by a trusted source, or by being accepted by the user). But to do something with this particular file, an admin should be starting up the browser really.

Fault policy files in MDS repository is not working..

Hi All,
I have created my fault policy and fault bindings file and tested in my local project. It worked fine.
To make it available in MDS,
I added the files under JDeveloperHome/jdeveloper/integration/seed/apps/faulthandling
I deployed this MDS repository to my server by the below method.
I created a new generic application, then a generic project, to which I added a new Deployment Profile of type JAR file.
To the JAR file, I added my folder in which the policy files exist. I created a SOA bundle from the ‘Applications’
Then I deployed the project to my server finally.
For all these things I refferred to
http://www.orafmwschool.com/soa-11g-mds/
Now in my adf-config.xml I have made changes as follows.
<metadata-store-usage id="mstore-usage_2">
<metadata-store class-name="oracle.mds.persistence.stores.file.FileMetadataStore">
<property value="D:\StudyForInstalling\SOA11gHome\jdeveloper\integration" name="metadata-path"/>
<property value="seed" name="partition-name"/>
</metadata-store>
</metadata-store-usage>
Then in my composite.xml I have,
<property name="oracle.composite.faultPolicyFile">oramds:/apps/faulthandling/fault-policies.xml</property>
<property name="oracle.composite.faultBindingFile">oramds:/apps/faulthandling/fault-bindings.xml</property>
I hav shutdown the partnerlink service.
Now, I can see remote exception while executing. My fault policy files are not executing.
In the same apps/ I have my PurchaseOrder.xsd file. When I tried importing the schema to my project from the mds, it is working fine.
I used like this in my wsdl.
<import namespace="http://www.order.org" schemaLocation="oramds:/apps/faulthandling/PurchaseOrder.xsd" />
Why is my faultpolicy file not working?
Kindly help me
Thanks,
Sabarisri .N

I am not sure if we can use oramds references as properties values in composite.xml. Did you try with preferences ??

Help me

It could mean that the location for MDS in the code isn't correct.
Can you re-verify the path provided for MDS?

Runtime parsing of policy.file - from source

Hi All
Decided to post here sinceI did not find any similar topic on forums and googling did not solve this.
Is there any way to parse polic.file like input at runtime? PolicyTool. PolicyFile are classes that do that but:
1. all methods are private so it does not give much place to have fun - cant make PolicyFile to read from StringReader for instance.
2. they make immedaite changes to jvm wide Policy object ? without access to installed code sources.
The question is is there a way to parse policy.file like data in a way that all goodies from PolicyFile are considered? - I mean keystore, principials, etc etc.
Or is it perfectly legal to create CodeSource and permissions from what is passed and dont worry about location of keystore or verification of signature?

You can work-around this by removing the language="java" altogether. The
          default is "java" and I don't expect anything else to be supported for a
          very long time to come!
