===== 6.2 Object Access Across Contexts =====

The applet firewall confines an applets actions to its designated context. To enable applets to interact with each other and with the Java Card RE, some well-defined yet secure mechanisms are provided so one context can access an object belonging to another context.  

These mechanisms are provided in the Java Card API and are discussed in the following sections: 

 

  *[[6.2.1_Java Card RE Entry Point Objects| Section 6.2.1, Java Card RE Entry Point Objects]]    

  *[[6.2.2_Global Arrays| Section 6.2.2, Global Arrays]]    

  *[[6.2.3_Java Card RE Privileges| Section 6.2.3, Java Card RE Privileges]]    

  *[[6.2.4_Shareable Interfaces| Section 6.2.4, Shareable Interfaces]]
