HELP: How do i include a policy file when embedding a JApplet

This is the problem i'm facing.I've been able to successfully grant my japplet permission to access resources on the c: drive. When i run it using appletviewer there's no problem, it's able to access the database on the c: drive but when i embedd it in my html page it fails to access the database (i.e it is unable to include the policy file). Does anyone know how to get around this problem?

You can not directly include a policy within an applet. This would be a security risk.
In general you have 2 choices if you wish to grant an applet more rights than it has per default:
1. You can sign it.
2. You change your local policy file.
ad 1:
You can generate a keypair using keytool and sign the applet with jarsigner. (you need to create a jar file first)
when your applet is then loaded in the browser, a popup asks the user, if he wanna trust the signer. If the user clicks no, the applet is executed with standard applet rights. If the user clicks yes, the applet is executed with full permission (like an applet from file:/*)
ad 2:
use policytool to create/change a policy file in your home directory. You can describe the applet either with a path (=codebase) or with some meta-information like signer.
create a policy that fits your need, and save the file.
next time you execute your applet in the browser, the policy will grant the applet additional permissions.
There is a third option. You can mix 1 and 2.
You can sign your applet, and create a policy for all applets signed by you.
Then there will be no popup, and the applet has automatically the rights you defined in the policy file.
But I would suggest to consider the possibility to write a stand-alone application, instead of granting an applet access to the local hard disk.

How can I include my database file into my jar file?

Hi,
I am doing several tests for the jar command....
I tried to put the database file into my jar file, but when the program run, it just couldn't find the database file, so how may I include the database file into the jar file? Not only that, it also can't find the policy file etc.

sorry, I think I found the solution, I should have had read the API more carefully.

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.

If you managed to get to the point where the applet container is created (the "gray square"), but the form never appears then you can assume one or more of the following has occurred:
1. The JRE crashed after startup. Many times, but not always, if such a crash occurs it will leave a JRE dump file on the desktop. Its content may help to identify the cause.
2. The Forms runtime crashed at startup. Many times, but not always, a Forms dump file will be created on the server. Its content may help to identify the cause.
3. The Forms runtime was unable to start at all. This can occur on unix systems when/if there is a resource or permissions issue. One of the more common causes is if the file descriptor (nofiles) value is set too low.
4. The applet is actually running, but has attempted to display a dialog box and is awaiting your acknowledgement, but the box was wrongfully sent to the background behind the browser. A similar issue was reported in one of the JRE 1.6.0_xx series, however I don't recall which one. Uninstall your current version and install the latest which is 1.6.0_27
There are other possibilities, but these are most common.
I would recommend the following:
1. Uninstall any JRE older than 1.6.0_27. Reboot. Install 1.6.0_27
2. Set networkRetries=5 in formsweb.cfg
3. Set FORMS_TIMEOUT to 15 (default). Setting to a high value as you have is not recommended and is rarely necessary.
4. Verify that the test form works. For example:
http://machine:port/forms/frmservlet?form=test
5. It appears that you are trying to use WU_TEST_106.fmx. Instead, download an updated version of this file (the name has also changed)
http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/196249.zip
6. Ensure that you have compiled webutil.pll into .plx. Do not use an old version of this file. The installation will include one. If not, check for it in an installation that also includes the Builders.

How do you use .wsse policy file from Java Client?

I'd like to call a WSSE enabled web service from my Java client but setup my encryption/signing requirements with a .wsse policy file.
I know how to call a web service by programmatically setting up the security headers as described in:
http://e-docs.bea.com/workshop/docs81/doc/en/core/index.html
But how can I do the same thing by simply using a .wsse file?

How can I attach a policy file to a applet in IE55?

I want to use jdbc in applet, so I had to run IE55 with a policy file, how can I set it?
thant u very much.

Search the JDBC forum. It has been explained in there.

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.

How can I include a javaScript files from within jsf component

Is there any way using which I can include javascript files from my jsf component. Because otherwise I have to write all the javascript commands using writer.write which is very tedious rather than this I just want to include the javascript file which contains all the functions required. Also I want that this file should be included only once irrespective of the number of components included.
Thanx in advance

This doesn't depend on JSF. You need to include a script tag, like:
<script src="/path/script.js"
language="JavaScript" type="text/javascript"></script>
If you want to include this only once, make a file included into every page, into which you can put other resources to be included along with this script.
HTH,

Need help - How to check online status of file?

Hi.
I'd like to make my flash app checks whether a particular file is online.
Let's say this file is 1MB. How do I make it so that when the flash app checks the URL of the file, it won't download the whole thing?
That is, once the flash app confirms that the file is up, it immediately cancels the download and displays a status message that the file is up. And if there's a 4xx or 5xx message, it will report appropriately.
I'm a total newbie, so I don't know how to go about this. I'd appreciate it if you could point me in the right direction.
Thanks.

you can use the filereference class'es download() method and its listener's onProgress() method.
