hi khushi, you can make the name attribute of all the textfields generated same(name="TField"), and make an String array and its getter amd setter methods[get/setTField(String  _tFields)]. the struts will autometically fill in this field in form bean.
hope this work with you too(it worked in mine case).
The best way to deal with this type of scenario in Struts is to use "Indexed Properties". You will find an explanation of how to use indexed properties along with a simple example in the JavaRanch Struts FAQ, question number 6.
