Setting converter pattern in java

I am using a DoubleConverter in my backing bean as part of a dynamically created page as follows:

HtmlInputText htmlAmount =new HtmlInputText();

...

Converter converter =new DoubleConverter();

htmlAmount.setConverter(converter);

...

I need to set the pattern for this converter. How do I do this? There is no setPattern or applyPattern method on the DoubleConverter.

Thanks in advance.
