Can't set a codeBase in my .policy file

[Dupont Girard]

Hello,
When i run the following java code:

FilePermission fp = new FilePermission("C:/workspace/CLO_TP3/lib/libM2/tp2/container_v2.jar", "read");
AccessController.checkPermission(fp);

I get this exception:

Exception in thread "main" java.security.AccessControlException: access denied ("java.io.FilePermission" "C:/workspace/CLO_TP3/lib/libM2/tp2/container_v2.jar" "read")

Here is my file .policy:

grant codeBase "file:C:/workspace/CLO_TP3/lib/libM2/tp2/*"  {
	permission java.io.FilePermission "container_v2.jar","read";
};

But it works fine if i remove the codeBase and set the full path as follow:

grant {
permission java.io.FilePermission "C:/workspace/CLO_TP3/lib/libM2/tp2/container_v2.jar","read";
};

Is there something wrong with the codeBase ?
Please help me !

No. The way you are specifying it is wrong.

Note: a codeBase value is a URL and thus should always utilize slashes (never backslashes) as the directory separator, even when the code source is actually on a Win32 system. Thus, if the source location for code on a Win32 system is actually C:\somepath\api\, then the policy codeBase entry should look like:

Thank you for your quick response.
Still get the same error, here is my new code:

FilePermission fp = new FilePermission("C:\\workspace\\CLO_TP3\\lib\\libM2tp2\\container_v2.jar", "read");
AccessController.checkPermission(fp);

.policy file:

grant codeBase "file:C:\workspace\CLO_TP3\lib_libM2\tp2\*"  {
	permission java.io.FilePermission "container_v2.jar","read";
};

Did you visit the link?
Did you notice this?

grant codeBase "file:/C:/somepath/api/" {
        ...
    }

i tried many things, but none of them works.

Here are my code as you you told me and as i read on the website:

FilePermission fp = new FilePermission("C:\\workspace\\CLO_TP3\\lib\\libM2\\tp2\\container_v2.jar", "read");
		AccessController.checkPermission(fp);

grant codeBase "file:/C:/workspace/CLO_TP3/lib/libM2/tp2/*"  {
	permission java.io.FilePermission "container_v2.jar","read";
};

it gives me the same exception

Many thanks
