Invoking a remote method on a server object [4] 

 

 

 

 

 

The purpose behind RMI is to make all the implementation details transparent to the programmer so that 

remote objects and methods work just like the local objects and methods.

Miscellaneous Concerns  

 

Applet Security 

 

Web browsers like Netscape allow applets to read and write data only on t he host that serves the applet [4, 

pg. 589] i.e. it will let the applet connect only to sockets on the computer from which the applet came. The 

write restriction prevents applets from planting viruses or altering important files on the local computer. 

The read restriction does not allow applets to browse files on the local computer for sensitive information, 

such as credit card numbers, open a socket connection to the applet host, and write the information back.
