As I’m new to JSF framework, wanted to know how to add the user

  • 0

As I’m new to JSF framework, wanted to know how to add the user entered data to the database.
More clearly, i’m using jsf with jsp, my jsp contains some input fields and a submit button.How do i capture all the user entered data and send it as input paramters for the button, as my back end takes all these as input parameters and updates the table with a new record.

Please look into my code and lety me know my mistake

Registration.jsp

 <f:view>
  <h:form>

Registration Bean

public class VendorRegBean {
private String stuNo;
private String stuName;
private String standard;
private String school;

  // getters and setters

    public void submitDetails() {
    Map requestMap = context.getExternalContext().getRequestParameterMap();
      String stNo = (String) requestMap.get("sNo");
      String stName = (String) requestMap.get("sName");
      String stndrd = (String) requestMap.get("std");
      String scl = (String) requestMap.get("schl");
    vReg.stuRegistration(stNo ,stName ,stndrd ,scl );

    You don’t need to get the parameters from the request parameter map as long as you register your bean as managed bean and provide getter and setter methodes for your bean members.

    Use annotations for your bean to declare it as managed bean. Getter and setter example are given for stuNo member:

    import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

    @ManagedBean
    @SessionScoped
    public class RegBean {
      private String stuNo;
      ...


      private String getStuNo() {
        return stuNo;
      }

      private String setStuNo(String stuNo) {
        this.stuNod = stuNo;
      }
    }

    In the view you have to reference the managed bean with first letter lower case, such as:

    <h:inputText value="#{regBean.stuNo}"/>

    Your command button doesn’t need <f:param>, simply use:

    <h:commandButton id="submitBtn" value="Submit" action="#{regBean.submitDetails}"/>

    Then all parameters are automatically available in your submitDetails method and you don’t need to get them from the parameter map.
