[Soot-list] one question about "No main class given.Inferred 'helloworld2' as main class."

[jiangfan shi]

Hello,

When I apply my transformer to my application classes, helloworld.java
and helloworld2.java, I encountered an warning "No main class
given.Inferred 'helloworld2' as main class."

My options for soot is following:

java soot.Main --app -w helloworld

==============the following is helloworld.java==============

public class helloworld {
	public static void main(String[] args) {
		System.out.println("hello world");
		helloworld2 tmp2=new helloworld2();
		tmp2.processOctetMsg();
	}
	
	void open1() {
	}
	
	 void processOctetMsg(){
		 System.out.println("processing in h1");
		 helloworld2 tmp2=new helloworld2();
			tmp2.open2();
	}
}
====================The following is helloworld2.java======================


public class helloworld2 {
	public static void main(String[] args) {
		System.out.println("hello world");
		helloworld tmp=new helloworld();
		tmp.processOctetMsg();
	}
	
	void open2(){	
	}
	
	void processOctetMsg(){
		System.out.println("processing in h2");
		helloworld tmp=new helloworld();
		tmp.open1();
	}
}


Any hints about the soot warning?

Thanks in advance, and I appreciate your answers.
