my bean

 package DC1;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.event.ActionEvent;

@ManagedBean(name = "ctrbean")
public class ctrbean {

public ctrbean() {
}

private String id ;
private String pa;
private String name;
private String rank;
private String father ;
private String dob ;

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getPa() {
    return pa;
}

public void setPa(String pa) {
    this.pa = pa;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getRank() {
    return rank;
}

public void setRank(String rank) {
    this.rank = rank;
}

public String getFather() {
    return father;
}

public void setFather(String father) {
    this.father = father;
}

public String getDob() {
    return dob;
}

public void setDob(String dob) {
    this.dob = dob;
}

public void insert(ActionEvent ee)
{
 avDC1 avd = new avDC1();
 avd.connect();


 }
 }

My Database class

package DC1;

    return rs;
}

public void setRs(ResultSet rs) {

 public void connect()

 }


public void Searchall(ActionEvent ee)

    e.printStackTrace();
    return;

}

if (connection != null) {
    System.out.println("You made it, take control your database now!");
} else {
    System.out.println("Failed to make connection!");
}

String  sql = "SELECT * FROM AVIATION" ;

Statement pdt = connection.createStatement();
 //        pdt.setString(1,ID );
 //        pdt.setString(2, panumber);
 //        pdt.setString(3,name);
 //        pdt.setString(4, rank);
 //        pdt.setString(5,father );
 //        pdt.setString(6, dob);

  rs =  pdt.executeQuery(sql);
  rs.next();

  String a = rs.getString("NAME");
  connection.close();

} catch (SQLException ex) {

 Logger.getLogger(avDC1.class.getName()).log(Level.SEVERE, null, ex);

}
} //end of search-all

}//end of class

This is the exception:

java.lang.UnsupportedOperationException: Not supported yet.
    at DC1.person.<init>(person.java:33) 
    at DC1.NewClass.<init>(NewClass.java:22) 
    at DC1.ctrbean.insert(ctrbean.java:76) 

Answer 1

DC1.person.java line 33 is explicitly throwing an UnsupportedOperationException. Perhaps you or your colleagues put that there to indicate that implementation is not complete. Otherwise you should remove the statement

throw new UnsupportedOperationException("Not supported yet");
