Examples of ServicePermission

javax.security.auth.kerberos.ServicePermission
This class is used to protect Kerberos services and the credentials necessary to access those services. There is a one to one mapping of a service principal and the credentials necessary to access the service. Therefore granting access to a service principal implicitly grants access to the credential necessary to establish a security context with the service principal. This applies regardless of whether the credentials are in a cache or acquired via an exchange with the KDC. The credential can be either a ticket granting ticket, a service ticket or a secret key from a key table.
A ServicePermission contains a service principal name and a list of actions which specify the context the credential can be used within.
The service principal name is the canonical name of the {@code KereberosPrincipal} supplying the service, that isthe KerberosPrincipal represents a Kerberos service principal. This name is treated in a case sensitive manner. An asterisk may appear by itself, to signify any service principal.
Granting this permission implies that the caller can use a cached credential (TGT, service ticket or secret key) within the context designated by the action. In the case of the TGT, granting this permission also implies that the TGT can be obtained by an Authentication Service exchange.
The possible actions are:
```
 initiate -              allow the caller to use the credential to initiate a security context with a service principal. accept -                allow the caller to use the credential to accept security context as a particular principal. 
```
For example, to specify the permission to access to the TGT to initiate a security context the permission is constructed as follows:
```
 ServicePermission("krbtgt/EXAMPLE.COM@EXAMPLE.COM", "initiate"); 
```
To obtain a service ticket to initiate a context with the "host" service the permission is constructed as follows:
```
 ServicePermission("host/foo.example.com@EXAMPLE.COM", "initiate"); 
```
For a Kerberized server the action is "accept". For example, the permission necessary to access and use the secret key of the Kerberized "host" service (telnet and the likes) would be constructed as follows:
```
 ServicePermission("host/foo.example.com@EXAMPLE.COM", "accept"); 
```

org.osgi.framework.ServicePermission
A bundle's authority to register or get a service.
- The {@code register} action allows a bundle to register a service on thespecified names.
- The {@code get} action allows a bundle to detect a service and get it.
Permission to get a service is required in order to detect events regarding the service. Untrusted bundles should not be able to detect the presence of certain services unless they have the appropriate {@code ServicePermission}to get the specific service. @ThreadSafe @author $Id: ff7fc46dd623c0a09b49965048dd6faa2b111b39 $
