Hi all, i am new to shell scripts and have one doubt.

Can we call ava classes/methods from shell scripts? if yes how?

Yes you can call java classes.

Code:

#! /bin/ksh

export CLASSPATH=/dir/containing/the/class:$CLASSPATH

/path/to/java HelloWorld

Lets say your classfile HelloWorld is in the directory ~/java/samples/class. Then you need to either
- add that path to the classpath setting
- or add a . to the classpath.

Calling methods is the class's responsibility. It depends on how you have coded your class.

Yes but from shell script, we call class like path/to/java classname

so if i want to call method classMethod, call will be like this?

"path/to/java classname.classMethod()"
