Specific instance/Non Singleton

Question

How to instantiate java class with parameters and use the same instance through out the application?

What i want to do is when a tibco esb requests a web service call to my application,i will capture user information(user name) in one pojo class so that I can use this pojo class and user information at other places in application also for this particular tibco request.

This question might sounds crazy but I would like to implement something like this in my application.Waiting for your thoughts guys.

You can use a ThreadLocal solution:

public class MyClassInstanceHolder {
    private static ThreadLocal<MyClass> instance = new ThreadLocal<>();

    public static setInstance(MyClass instance) {
        instance.set(instance);
    }
    public static MyClass getInstance() {
        instance.get();
    }
}
...
MyClass myInstance = MyClassInstanceHolder.getInstance();

So in that thread you'll have access to the object stored in that ThreadLocal.
