beans and C code in java prog.

[Nishi Bhonsle]

I have to write a bean that triggers an event that removes a given file on the condition of the file system being full.
Since I am new to java beans, can you someone please let me know if I could do the follow the below approach-->

Create 3 classes --
FileSystemFullListener--interface extending EventListener
FileSystemFullBean--source bean that fires the systemFull event
FileSystemFullEvent
I will write a C program to detect the systemFull event. I should be including the systemFull call in the FileSystemFullEvent class, right?
How can I execute a C program call through a java program?


Thanks.

You have two options: if the C program is indeed a stand-alone
executable application, you can use one of the java.lang.Runtime.exec()
methods.

If, instead the C code you want to call is part of a library, you're
going to have to use JNI, the Java Native Interface.

HTH!
