What is a .ALL file?
The file extension .ALL is associated with a Cubasis Project File, which is a type of security policy file used by Java RMI (Remote Method Invocation)-enabled technologies. These technologies include Apache River (formerly known as Jini) and GigaSpaces. The .ALL file contains data access permissions and is specifically configured to grant full permissions to all entities. This setup is typically used during the development phase of applications, where developers are working within a secure environment and need unrestricted access to resources.
The .ALL file, often named "policy.all," plays a crucial role in managing security policies for applications that use Java RMI technology. This file is used to specify security permissions and is passed as a parameter when starting a Java RMI application. For example, to invoke a Java RMI application with full permissions, you would use the command: ``` java -Djava.security.policy=policy.all ``` This command tells the Java system to use the "policy.all" file as the security policy for the application being launched.
Programs that can open .ALL files include Apache River and GigaSpaces. However, it's important to note that Apache River has been discontinued, so while older documentation might still reference it, ongoing support and updates may not be available. GigaSpaces continues to support the use of .ALL files in its environment.
In summary, the .ALL file extension is crucial for developers working with Java RMI technologies, allowing them to configure and manage security permissions easily during the development of distributed applications.
