NIGHTMARE! Signed Applet - No Access. Please Help.

Hi:
I'm trying to make a signed applet gain access to my directory structure.
I created a simple applet to test with one line:
sErr = System.getProperty("user.dir");
The code is below.
I sign it using the following:
keytool -genkey -keyalg rsa -storepass MyCerts
As you can see I'm using the default keystore but I've tried it by using -keystore MyKeystore too.
It runs me through all the questions which I answer, no problems.
Then I sign it:
jarsigner -signedjar SSignedApplet.jar SignedApplet.jar MyCerts
It asks for the passwords which I enter.
It completes without error and the SSignedApplet.jar file shows up in the directory.
If I open the signed jar file it has all 3 of the files in the META-INF folder and the Manifest file looks right to me.
I upload the jar and the Default.asp file to a Web server (I've tried localhost and a remote host).
I open the page and the pop up comes up asking if I want to trust the unverified applet. I click 'Run'.
Once the applet is 'Started' I click the 'Get Properties' button and I get the error:
access denied (java.util.PropertyPermission user.dir read)
I've tried 2 examples that work fine on my machine (that I didn't write).
The first is by Francois Orsini (Derby Demo) and the other is by Laura MacDougal (successfully wrote a file to my user.dir directory).
No matter what I do, I can't sign an applet and make it access anything.

Thank you for reading my reply in your other thread:
http://forum.java.sun.com/thread.jspa?threadID=762212&messageID=4368224#4368224
If you've really run through it you would have known that code called from
javascript is not trusted and you have to use doprivileged (hey its in bold...
why would that be?).
Call getProp from init within the applet and you've got no problem.
As for your imageIcon, creating one with string as a parameter
the string is used as input for a File. I had no problem loading one with a signed applet.
I'll post the example later in your other thread.

I need some help with my java game using applets, CAN SOMEBODY PLEASE HELP

Hi,
I am in the process of creating a RPG program using Java. I am not very experienced with java, however the problem i am currently facing is something i can't seem to figure out. I would like to draw a simple grid where a character (indicated by a filled circle) moves around this grid collecting items (indicated by a red rectangle). When the character moves on top of the grid with the item, i would like it to disappear. Right now i am not worrying about the fact that the item will reappear after the character moves away again, because sometimes, when the character moves over the item, nothing happens/another item disappears. i have been at this for 4 days and still cannot figure out what is goign on. can somebody please help me? it would be most appreciated.
Thanks
PS if i needed to send you my code, how do i do it?

Thank you for replying.
The thing is, I am taking java as a course, and it is necessary for me to start off this way (this is for my summative evaluation). i agree with you on the fact, however, that i should go in small steps. i have been doing that until this point, and my frustration caused me to jump around randomly for an answer. I also think that it may just be a bug, but i have no clue as to how to fix it, as i need to show my teacher at least a part of what i was doing by sometime next week. Here is my code for anybody willing to go through it:

APPLET in jsp (please help)

hi ,
can someone tell me please how can i load an applet dynamically in my jsp
i have some thing like this:
<APPLET code=" SimpleApplet.class" width=800 height=500>An Applet</APPLET>
in this case i have allways to copy the "SimpleApplet.class" to the same directory on my jsp and the redeploy.... how can i make it dynamically??
the "SimpleApplet.class" is in the xxx.jar of my appllication....
please any idea??
thanx

First thing is the applet cannot access the classes in the WEB-INF folder so all the applet classes have to be in the webroot directory.
Change ur build script so that it will copy it in the web root directory
Try this
<applet code="SimpleApplet.class" archive="SimpleApplet.jar" name="SimpleApplet"
codebase="." width=325 height=325>
<PARAM NAME="fileName" VALUE="test">
<PARAM NAME="basePath" VALUE="test">
</applet>
Review this tutorial and you should find the problem:

Applet Problem. Please Help.

Hello,
I've written an rmi-based application and would like to run a client side as an applet. My client app works fine when I type: "appletviewer app1.html" but when I run it in a web browser, none of the *.gif images are there. Can somebody please tell me why I can't see *.gif images in web browser? I looked at java.policy and said something like:
grant codeBase "file:C:/Sun/AppServer/jdk/bin/*" {
     permission java.security.AllPermission;
with no effect
I then read CoreJava book and implemented:
grant
permission com.sun.rmi.rmid.ExecPermission
     "${java.home}${/}bin${/}java";
     permission com.sun.rmi.rmid.ExecOptionPermission
     "-Djava.security.policy=*";
and this one too:
grant
     permission java.security.AllPermission;
But, I am not sure what to do with these policy files other than add them in the \jre\lib\security directory. Please tell me what should I do?
Thank you,
Victor.

Wrong sign in COPA. please help!

Hi,
I'm an SD consultant, so forgive me if this question is a bit fuzzy. I need help figuring out how the +/- signs are used in COPA.
I have two COPA postings, both from Debit Memos, and both posting to cost elements with category 12.
1) Condition Type Y represents Deferred Costs. It is posted via SD to FI with a DR and to PA with a DR.
2) Condition Type Z represnts Royalty Income, but we want it reflected <i></i>not as income, but as a credit to cost<i></i>. It is posted via SD to FI with a <b>CR</b> and to PA with a DR. However, if I make a manual posting in FI, it is reflected in PA correctly.
Does anyone have ideas as to why this is happening? The condition types only differ in the Plus/Minus setting (Y = ' ' either ; Z = 'A' positive) and the Condition Category field. Both conditions are transferred to PA with "Transfer +/-" = ' '.
Thanks!!!!
Ben

Hi Ben,
Please check if in pricing condition if Transfer values with +/- signs flag is ON
Also please refer below link:

Please assign points as way to say thanks

Problems understanding open text for access, please help

Hi all,
I'm experiencing some problems with this script, and I think knowing what the error is will help me a lot to understand better how applescript handles access to files.
When i launch this script it tells me somethihng like "document some object has not been opened" (could be slightly different in english).
So, i guess is a problem with openening and closing, but as you can see i open and close the doc, so I shouldn't encounter this problem. Do I?
Thanks for any tip!
set Report to "myfile.txt"
-- in case previously not closed I'll close again
try
close access Report
end try
set the_file to (open for access Report with write permission)
write return to the_file starting at eof
write "test" to the_file
write return to the_file
write return to the_file
close access the_file
repeat with numero from 1 to 3
write numero to the_file starting at eof
write return to the_file
write return to the_file
close access the_file
end repeat

Each time your application is run the files associated with it will also be released, so all you need to do is make sure that each open is balanced with a close. This can be done easiest by using a handler that has been tested, so you don't have to worry about leaving something out elsewhere in your script. For example:
on run -- example
          set report to ((path to desktop) as text) & "myFile.txt"
write_toFile_("testing one" & return, report)
write_toFile_("testing two, three" & return, report)
write_toFile_("testing again" & return, report)
end run
on write_toFile_(someThing, someFile)
try
    set theOpenFile to (open for access someFile with write permission)
    write someThing to theOpenFile starting at eof
    close access theOpenFile
on error -- make sure file is closed on any error
    try
      close access theOpenFile
    end try
end try
end write_toFile_

public class calcg extends JApplet implements ActionListener{ in many different ways, but it didn't work. Can sombody help me make it work?
Below is the source code for my calculator program.
Thanks in advance,

//execute application
public static void main( String args[] )
    calcg application = new calcg();
    application.setDefaultCloseOperation(
JFrame.EXIT_ON_CLOSE );
}

Ok I think I know what you problem is.
First move the main method above the calcg method ok. Just to make it easy.
Then you did something like
public static void main( String args[] )
calcg application = new calcg();
>> application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); }}
the arrows indicate your error. You need to put the setDefaultCloseOperation inside the calcg method then you would put this:
public static void main(String[] args)
calcg application = new calcg();
application.calcg();
see you call the application to run the calcg method which will start your program.

Signed Applet to Access Smart Card Reader

I am trying to develop an applet that will access a smart card on the client's side. The applet will need to load the PKCS#11 library(.dll) from the client side.
What is the most secure way to implement this design?
1 solution I am think of is to use Java Web Start which will download the applet onto the client desktop. Is this the right way?
Is there a solution where the applet can run in the browser and access the smart card without downloading the applet?
Thanks.

This is a duplicate of this and is probably better dealt with in the WebStart forum. I'm locking this thread.

NIGHTMARE! Signed Applet - No Access. Please Help.
