Is there a way to reference a component when all you have is a string with
the name of the component in it? The component has been created in the code.
A sequence is used to create unique names for the component so all i have is
a string with for the name.

Assuming that the component is accessible to the class that wants to access
it, you can find the component using the Java Reflection API:

Field f = container.getClass().getField(componentName);
Component c = (Container)f.get(container);
