Abstract: A solution is proposed for populating a policy file in a Java environment automatically. For this purpose, there is provided a wrapper for a security manager in charge of controlling any access to protected resources. A generic Java application is run in a test environment. Whenever a specific operation must be executed on a secured resource, the Java application submits a corresponding permission request to the wrapper. The wrapper forwards the permission request to the security manager, which verifies whether the required permission is available in the policy file. The wrapper logs any denied permission. In any case, the wrapper always grants the required permission to the Java application, so that its operation can continue without any problem. At the end of the running of the Java application, the logged missing permissions are added to the policy file.

Abstract: A solution (300) is proposed for populating a policy file (320) in a Java environment automatically. For this purpose, there is provided a wrapper (325) for a security manager (315)—in charge of controlling any access to protected resources. A generic Java application (310) is run in a test environment. Whenever a specific operation must be executed on a secured resource, the Java application submits a corresponding permission request to the wrapper (A1). The wrapper forwards the permission request to the security manager (A2), which verifies whether the required permission is available in the policy file (A3-A4). The wrapper logs any denied permission (A5); in any case, the wrapper always grants the required permission to the Java application (A6-A7), so that its operation can continue without any problem. At the end of the running of the Java application, the logged missing permissions are added to the policy file (A8).

Abstract: A method and a corresponding apparatus for controlling and metering usage of software products on a computer are proposed. In a license manager software product, when several licenses are available for the same product a method for determining the best license is proposed in order to maximize the exploitation of the licenses. The solution of the invention is based on the idea that, if a choice is possible, it is preferable to use a license with a narrower scope, leaving a license with a wider applicability for future needs. According to the present invention the licenses are stored on a catalogue with an associated list of attributes indicative of usage constraints of the product. The licenses are ordered according to predetermined attributes optimization criteria, so that when a request is received, the license manager can easily find the best license, i.e. that license, suitable for the requested use, having the highest usage constraint, saving the more flexible licenses for future needs.
