2004.12.14 This is the problem that the Elearning project was discovered yesterday, and the corresponding type of Numberic type

The corresponding type of Numberic type in the PostgreSQL database in Java is BigDecimal.

Java.math.bigDecimal;

Usage:

the first method:

You assign it in the reset method in the AFORM. public class AActionForm extends ActionForm {private String usertype; public void setUsertype (String usertype) {this.usertype = usertype;} public String getUsertype () {return this.usertype;} public void reset (ActionMapping actionMapping, HttpServletRequest httpServletRequest) {usertype = "P"; / / here is attribute to support}}}

The second method: public class AAction extends Action {public ActionForward execute (ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throwsNWException {AActionForm aForm = (AActionForm) form;

AFORM.SETUSERTYPE ("P"); .......}
