JavaDB error 'Schema 'ROOT' does not exist' - glassfish

Question

I am new to Java Server Faces and JavaDB. I am struggling to connect due to my database due to an error stating "Schema 'ROOT' does not exist". I'm pulling my hair out over this and I know it must be something simple. I did not set a username or password for the database "guest_book". The database exists under the APP schema. The managed bean is coded as follows..
package com.jsf;
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.annotation.Resource;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.sql.DataSource;
import javax.sql.rowset.CachedRowSet;
/**
*
* #author pctdeveloper7
*/
#ManagedBean(name="guestbean")
#SessionScoped
public class GuestBookBean {
private String date;
private String fname;
private String lname;
private String email;
private String message;
#Resource( name="jdbc/guest_book" )
DataSource ds;
/**
* Creates a new instance of NewJSFManagedBean
*/
public GuestBookBean() {
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getFname() {
return fname;
}
public void setFname(String fname) {
this.fname = fname;
}
public String getLname() {
return lname;
}
public void setLname(String lname) {
this.lname = lname;
}
//return a resultset of entries
public ResultSet getEntries() throws SQLException{
//Check if was injected by the server
if(ds == null)
throw new SQLException("Unable to obtain datsource");
//get connection from datapool
Connection conn = ds.getConnection("root","root");
//check if connection was successful
if(conn==null)
throw new SQLException("Unable to connect to DataSource");
try{
//Create a prepared statement to insert a new address book entry
PreparedStatement getMessages = conn.prepareStatement("Select * " +
"FROM MESSAGES ORDER BY lname, fname");
CachedRowSet rowset= new com.sun.rowset.CachedRowSetImpl();
rowset.populate(getMessages.executeQuery());
return rowset;
} finally{
conn.close(); //return connection to pool
}
}//End getEntries
//Save a new guestbook message
public String save() throws SQLException{
//Check if was injected by the server
if(ds == null)
throw new SQLException("Unable to obtain datsource");
//get connection from datapool
Connection conn = ds.getConnection();
//check if connection was successful
if(conn==null)
throw new SQLException("Unable to connect to DataSource");
try{
//create a preparedStatement to insert a new guestbook entry
PreparedStatement insertEntry = conn.prepareStatement("INSERT INTO"+
"messages values( ?, ?, ?, ?, ?)");
//define prepared statements arguements
insertEntry.setString(1, fname);
insertEntry.setString(2, lname);
insertEntry.setString(3, email);
insertEntry.setString(4, message);
insertEntry.setString(5, date);
insertEntry.executeUpdate();// insert the new entry
return "index"; //go back to the index page
}finally{
conn.close();//return connection to the pool
}
}//END Save()
}
The SQL used to create the database is as follows..
create table messages
(
fname varchar(25),
lname varchar(35),
email varchar(50),
message varchar(300),
"DATE" varchar(11)
);
Insert into messages
values('Jared', 'Rainey', 'jared.rainey.it#gmail.com', 'Hi!', '10-12-1982');
The connection pool is named GuestBookPool and the datasource is jdbc/guest_book. I didn't set passwords or username for anything and it was all created under the APP schema from what I understand. Any help would be greatly appreciated!

Answer 1

Instead of #ManagedBean(name="guestbean");
try #ManagedBean(name="guestbean", schema="APP"); or whatever your schema is.

Answer 2

If you are using JSF you can connect the to the database by creating an ApplicationContext in your Web-INF folder shown in project.
Create a singleton bean of you desired datasource.
The method that you are using is not a preferred one.
By the way, to help you more, may I ask which database you are using? Oracle, postgres, Access etc.?
