AccessControlException createClassLoader

[JavaCommando]

I'm using custom class loader and the Microsoft JDBC driver in my applet. When my class loader calls super() in the body of its constructor (creates new instance of class loader) I get

java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "createClassLoader")

Now, I have tried running applet through jnlp

<param name="jnlp_href" value="permissions.jnlp">

with

<security>
<all-permissions/>
</security>

...but the browser just freezes to death.

Later, I have signed the JAR containing my applet, and I still get

java.security.AccessControlException

Is there a solution to this? Please, don't suggest

grant {
permission java.security.AllPermission;
};

It's a heavy, not user-friendly solution.

Does the applet work with the shown changes to the .java.policy file?

[JavaCommando]

Yes.

It seems like signing should give you the permissions you need.

[JavaCommando]

1. keytool -genkey -keystore myKeyStore -alias me

2. keytool -selfcert -keystore myKeyStore -alias me

3. jarsigner -keystore myKeyStore jarfile.jar me

I've tried signing - no use:

java.security.AccessControlException
