Easiest way to populate a bean using servlet params

without using any big web framework (just servlets), do you know a ready to use small library that can populate my bean properties from the params of an http request?

Solution

  • You could take a look at Commons Beanutils, it has a whole bunch of methods for populating beans (including nested beans):

    http://commons.apache.org/beanutils/

    The method, in particular, that you want to look at is populate in BeanUtilsBean:

    public void populate(Object bean,
                     Map properties)
