The grant without a codebase gives the included permissions to all codebases. If you want to limit the permissions to a single codebase, move the permissions to the grant that specifies that codebase.

I've never been able to figure it out completely. It changes with each new version of the browsers. Here's a sample from my .java.policy file:

grant codeBase "file:/D:/JavaDevelopment/-" {
  permission java.io.FilePermission "<<ALL FILES>>", "read";
  permission java.util.PropertyPermission "*", "read, write";
};

grant codeBase "file:/C:/Miscellaneous/-" {
  permission java.io.FilePermission "C:/", "read";
};
/* These are for a search applet I use when searching local doc files */
grant codeBase "file:/E:/Java/-" {
  permission java.io.FilePermission "E:/", "read";
  permission java.io.FilePermission "E:/Java/Tutorial/", "read";
  permission java.io.FilePermission "E:/Java/Java-1_6_0/docs/", "read";
};

I put absolute path for the codebase and archive.

For instance, my java applet class is located at C:\Users\xh2453\IBM\rationalsdp\workspace_70\TestWebAppl\WebContent\WEB-INF\classes

How can I change it to fit HTML tradition?

NormR1 563 Posting Sage Team Colleague · Answer 2 · 2011-11-29T21:28:40+00:00

Read the doc for HTML syntax
Ask Google for how to code the applet archive= attribute
Ask Google for URL protocols.

I put everything in one directory (C:/Users/xh2453/IBM/rationalsdp/workspace_70/XuggleTest/bin) and call then from there and still get errors. Any clues for what's going on there?

Source code:

Buried in the middle of the error messages.
Your code needs permission to read files that are not from its codebase.
Move that image file to the folder with the .class files and try it.

What program generates that long error message you posted?

Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission java.library.path read)

It looks like you still do not have permission.

Did you look in the .java.policy file? Not the java.policy file. NOTE leading . in name
You can use the policytool program that comes with the IDE to edit the .java.policy file instead of using an editor.

After adding numerous permissions into my java.policy file, I finally got it to work. Thanks for your help.

What I've done for a quick way to test if your permissions file is being used, is to grant all permissions to all codebases. If the code now worked, then you could narrow down the permissions to the minimum.

mydreamgirl 0 Light Poster · Answer 11 · 2011-12-01T03:00:48+00:00

I put all permissions under grant {..}, not under grant codebase {...}. Do I need to do the same thing in grant codebase{ }?

mydreamgirl 0 Light Poster · Answer 12 · 2011-12-01T03:18:12+00:00

I am kind of struggling with the codebase thing. I am testing my applet in my pc. How can I define my codebase? Absolute path is not accepted. Even relative path is not working either.
