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?

How to handle the java.policy file ?

Can somebody tell me how to handle the java.policy file?
I always get java.net.SocketExceptions and java.security.AccessControlExceptions while connecting to an appserver from an applet.
What do I have to write in the java.policy file, where do I have to place it and do I have to call it in some way form my applet?
Thanks in advance.
don call

The java.policy file goes in your jre installation directory in .../jre/lib/security (there should be one there already).
I used it to allow otherwise restricted permissions for an applet using javax.comm. Add something like the following to the file:
grant codeBase "URL:http://yourDomainName/rootDirectoryOfYourApp/*" {
permission java.security.AllPermission;
This will give the applet downloaded from your site all permissions. You might want to give only certain permissions, I don't know.

Have file name with date working but appending the time to file name can't get a result

DECLARE @dt AS VARCHAR(26)
SELECT @dt = REPLACE(CONVERT(VARCHAR(26),getDate(),110),'-','-'
Have this appended to a filename like: log_01-15-2015. Don't know what to add to SQL code to get the get the time and append time in hours, min, sec. like: log_01-15-2015_10:01:33
DECLARE @dt AS VARCHAR(50)
SELECT @dt = REPLACE(CONVERT(VARCHAR,CURRENT_TIMESTAMP,110),'-','-') +'_'+ CONVERT(VARCHAR,CURRENT_TIMESTAMP,108)
EXEC master.dbo.sp_configure 'show advanced options',1
RECONFIGURE WITH OVERRIDE
EXEC master.dbo.sp_configure 'xp_cmdshell',1
RECONFIGURE WITH OVERRIDE
SET @bcpCommand = 'bcp "SELECT * FROM ##Temp ORDER BY barcode" queryout "C:\TEMP\Log\ContainerHistory_Log_' + @dt +'" -c -T'
EXEC master..xp_cmdshell @bcpCommand
I am trying to append to the file created with the date a time stamp but when appending the time part for the filename results aren't creating the file. If it's just doing the date part then it is working. Any idea what is wrong?

Since you added ":" to the file name, the file name is not valid. You can change ":" to "-".
DECLARE @dt AS VARCHAR(50)
SELECT @dt = CONVERT(VARCHAR,CURRENT_TIMESTAMP,110) +'_'+ REPLACE(CONVERT(VARCHAR,CURRENT_TIMESTAMP,108), ':', '-')
SELECT @dt

created by Sara.Forsberg in Adobe Acrobat.com Services - View the full discussionHi samueli11326032, Do you have PDF file or a Word document (.doc or .docx file) that you're trying to edit? To edit a PDF, you need to use Acrobat. If you have Word doc that you converted from PDF, you can download the file from your account at https://cloud.acrobat.com, so that you can open it and edit it in Microsoft Word. If you've made that far and are having trouble selecting/editing the text in Word, try triple-clicking in the text block that you want to edit. And, if I've completely misunderstood your question, let me know a bit more about the file that you're trying to edit it, and what software you're using, and I'll do what I can to get the issue resolved.

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.

.java.policy file problem

Is there someone who knows how to reinitialise the java policy file at runtime?
My signed applet writes a policy file to the users home directory, but that file is only used after closing the browser and surfing back to our page. It should immediatly use that new file.
Someone who got some experience with that...?
Regards

And is it true that if you use a Thawte or verisign certificate, you will not have to change the .java.policy file?

".java.policy" file where is this located

Hi,
Where is the .java.policy file located. Do I have to create it? Do I have to use any editor for this? Please help me.
Thank you,
Regards
Uma

It'll probably be in the lib/security directory of your JRE.
If you've got a JDK then it'll be something like jdk1.3/jre/lib/security/java.policy

Where to put java.policy file?

Under which directory the "java.policy" file must be kept in?

Hi!
The policy file must be indicated in the command line or by system property, when you starts the service, like the following: -Djava.security.policy = yourfile.policy. If you want to indicate another directory, you can do like this: -Djava.security.policy = C:\temp\yourfile.policy.
I hope it helps you,
Sandra.

How open and edit the coherence.xml file?

How can I open and edit the coherence.xml file?
I cannot find the coherence.xml file in the coherence.jar package.
Thank you,
June

If you are intent on changing the coherence.xml file, then you could use the JAR command (that comes with Java) to extract the coherence.xml file from coherence.jar and the later repackage the coherence.jar file using the udpated coherence.xml file, e.g.:
C:\java\opt\coherence-331\lib>jar -xvf coherence.jar tangosol-coherence.xmlextracted: tangosol-coherence.xml>
Instead of using JAR, on Windows you can associate the .JAR, .WAR and .EAR extensions with WinZip and use it to access / modify the contents of JAR files.
However, the suggested approach is as follows, and does not include any changes to the tangosol.jar file:
The tangosol-coherence-override-dev.xml file can be found in the coherence.jar file. After editing this file (in this case to define a unique value for the port system-property value for the multicast listener), save the file and add it to the server's classpath. When the server is executed, the values in the tangosol-coherence-override-dev.xml file will override any corresponding settings in the tangosol-coherence.xml file.Peace,

The type tool has a circle with a strike through on the bottom corner and won't insert words when iI type

I've just restored from a computer crash and re installed Creative Cloud 6 on my clean computer. Since then I've tried to use illustrator but can't get the type tool to function. It appears but has a small circle with a strike through on the bottom right corner and won't insert words when I type. I'm a newbie to illustrator and other Adobe products so please be gentle. Thanks for any help.

Thanks for your suggestion.
This was a bigger problem than I thought so I contacted support. The type issue was fixed in the repair.
BTW I am running Creative Cloud 2014 and not cc6 like I thought. Also on PC Windows 7
Here is the result:
I also have had a difficult time with Adobe Illustrator CC 2014 crashing upon launch. The support staff was great even though we had to work through several sessions. Below is the email explaining our final session.
This email is in regards with the issue you had been facing with Illustrator CC 2014.
While going through the installer logs, we found that there was an issue with the installation & the program installer had been denied access to several critical files & folders during installation.
This was the main reason for Illustrator crash as several critical components had not been installed properly.
We tried installing the program in a new user account & that worked.
Though the program has been installed properly now & is working in your old account, I will still strongly recommend you to get your computer user account repaired with a Windows 7 operating system diskette.
This is required so that you do not run into more trouble later while working with the Adobe Applications or even while installing other programs.
Avanish Divya was the final support person that successfully resolved my problems.
I hope this helps other panicked users.

HT5177 How can two people edit the same FCPX file? One company, so both people/computers share the same license. Example: I work on revision A and my boss takes it and makes revision B and gives it back to me using two separate computers.

How can two people edit the same FCPX file? One company, so both people/computers share the same license. Example: I work on revision A and my boss takes it and makes revision B and gives it back to me using two separate computers.

Have the project, events and media on one drive which is common to both macs.
You can download FCP X to both macs using the same Apple ID that it was purchased with.

How do I show the bookmarks toolbar while in fullscreen on Firefox 20? In older versions you could edit the userChrome.css file. Does that still exist?

After searching for this option, it appears it was very easy to do in older versions of firefox on windows 7. Many posts say you can edit the userChrome.css file to add:
#PersonalToolbar[moz-collapsed="true"] {
visibility: visible !important;
However, on 2 machines with firefox 20, I've searched for that file and cannot find it. Does it even exist any more? if not, how can I set firefox to go to fullscreen mode and continue to show the bookmarks toolbar? Unchecking hide toolbars does not work for the bookmarks toolbar.

userChrome.css does not exist by default. You can create it; it's an ordinary text file. Note that you do need a namespace at the beginning of the file.
You could try this:
@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
#PersonalToolbar[moz-collapsed="true"]{
visibility: visible !important;
#navigator-toolbox[inFullscreen="true"]{
margin-top:-62px !important;
I added the second rule to prevents the toolbar area from rolling all the way up. The specific value may need to be adjusted by a few pixels depending on your toolbar heights.
