It should be possible. I see a couple of issues with your serverless.yaml.

First you need to setup the version of java: runtime: java1.8.

Then you need to set the filename and the class name as the handler. For example for the file Foo.java with this content:

▶ cat Foo.java
package io.kubeless;

import io.kubeless.Event;
import io.kubeless.Context;

public class Foo {
    public String bar(io.kubeless.Event event, io.kubeless.Context context) {
        return "Hello world!";
    }
}

You will need to set the handler handler: Foo.bar.
