java application which starts on application-server start

[former_member471039]

hi,

how do i write a simple java project which can deployed on the sap netweaver application which gets started on startup?

i dont want to write a portalcomponent or something like that.. it just should be a sort of programm which simply starts and is deployed inside the applicaiton server.

hope you understand what i want,

thanks in advance,

constantin

Hello Constantin,

Here are three sample applications:

Just follow the steps from one of the tutorials and you will develop and deploy your first application.

hi,

thanks for your answer, but thats not what i wanted. i know how to write dynpros, j2ee applications etc.

okay.. let me try to explain it simple.

this is my java-code

public class Server {
	public static void main(String[] args) {
		System.out.println("i started with the sap application server, now i'm waiting to serve...");
		while (true) {
			// NOOP - wait for something
		}
	}
}

i just want that this application runs inside the sap application server... so i can deploy it (using nwdi and cms) and which runs at startup (maybe a deployment-descriptor)

hope you know what i want...

regards

Hello Contantin,

The J2EE Engine starts in 3 phases.

1. Startup of kernel

2. Startup of services

3. Startup of applications

In which phase do you want to execute your code?

Hi Constantin

In file META-INF\application-j2ee-engine.xml set property <start-up mode="always"/>

Hope this will help.
