Answer 1

i had tried the given two ideas but it's not working.the overall code i had used is
simple bean
public class Catg1 {
int catgid;
String catgname;
public String getCatgid() {
     return catgid;
public void setCatgid(String catgid) {
     this.catgid = catgid;
public String getCatgname() {
     return catgname;
public void setCatgname(String catgname) {
     this.catgname = catgname;
business bean
public class Catgdisp{
public static ArrayList catgDisplay()
          Catg1 catg1=null;
          ArrayList catg=new ArrayList();
          try{
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               con=DriverManager.getConnection("jdbc:odbc:dsn_library","erplibrary","erplibrary");
               st=con.createStatement();
               String query="SELECT catgid,catgname FROM mst_catg";
               rs=st.executeQuery(query);
               while(rs.next())
                    catg1=new Catg1;
                    catg1.setCatgid(rs.getInt(1));
                    catg1.setCatgName(rs.getString(1));
                    catg.add(catg1);
Managed Bean
public class display {
protected ArrayList catg = new ArrayList();
     public ArrayList getCatg()
          catg1 =Catgdisp. catgDisplay();
          return catg;
     public void setCatg(ArrayList catg)
          this.catg=catg;
