store quite huge object into request variable
MyObject o = new MyObject();
o.setObjectName(name);
request.setAttribute(myObejct, o);
These are correct steps how to make it, aren't they? But the object MyObject

I'd concentrate on the bit of code in your action:
request.setAttribute(serverBean, new Server());
Server s = (Server)request.getAttribute(serverBean);

If this returns null then nothing else

You shouldn't ever have to create the form yourself if you:

Do I also need to use the following line at the end

Is there a way around this issue?
