Question

I have a web application made with Spring that runs on Tomcat. On the same machine there is a normal Java application.

I would like to execute the Java application by calling it from the web server, but i want to make it so the application won’t use the server’s resources (it involves the training of a classifier so it may take up a lot of resources and time) and it must not hang the server (so it must be called asynchronously).

Is there any way to do that?

Answer 1

You have two options.

1. Start a separate JVM instance by doing a exec and using a java command.

2. Spawn a new thread – this will use server’s resources though.

You can also combine options 1 and 2 and create a thread that does the exec call.
