Creating a Grid Using Extjs and Loading Data from Database

First Creating Java Bean to set and get the Details from  DataBase.

package com.first;

public class GridStore {

    public String getEMAILID() {
        return EMAILID;
    }

    public void setEMAILID(String EMAILID) {
        this.EMAILID = EMAILID;
    }

    public String getFIRSTNAME() {
        return FIRSTNAME;
    }

    public void setFIRSTNAME(String FIRSTNAME) {
        this.FIRSTNAME = FIRSTNAME;
    }

    public String getLASTNAME() {
        return LASTNAME;
    }

    public void setLASTNAME(String LASTNAME) {
        this.LASTNAME = LASTNAME;
    }

    public String getMOBILENO() {
        return MOBILENO;
    }

    public void setMOBILENO(String MOBILENO) {
        this.MOBILENO = MOBILENO;
    }

    private String FIRSTNAME;
    private String LASTNAME;
    private String EMAILID;
    private String MOBILENO;



}
