Just refer to the variable "myCoolBean" in your java code/scriplets. It's the name of an object of class myPackage.MyBean that the
servlet container has instantiated for you. Just use it like you would any other object variable.
Ie,
myCoolBean.setSomeProperty(value);
String value = myCoolBean.getSomePropertyValue();
otherObject.invokeSomeMethodThatTakesAmyBeanObject(myCoolBean);
etc.
