 <input type="radio" name="quotation3" value="${i.widthCut},${i.lengthCut},${i.crossingNo},${i.jobWidthMulti},${i.jobLengthMulti},${i.layoutAmount},${i.layoutResult}"/>  

and this is my controller

 
public class AddQuotation3Controller extends SimpleFormController{

//	QuotationListDAO quotationListDAO;
	SelectedLayoutDAO selectedLayoutDAO;
	
	public void setSelectedLayoutDAO(SelectedLayoutDAO selectedLayoutDAO) {
		this.selectedLayoutDAO = selectedLayoutDAO;
	}
	
//	public void setQuotationListDAO(QuotationListDAO quotationListDAO) {
//		this.quotationListDAO = quotationListDAO;
//	}

You are trying to persist an a array of Strings directly - you can only persist mapped classes.

so...is there have any ways to get the data and save them in database?? because i have no experiences about this....Help me again

With JPA 2.0 you can use @ElementCollection on a collection class to persist the Strings and hibernate (also?) supports @CollectionOfElements
