Netbeans Java Enterprise Web Application: cannot find symbol class Table - netbeans

Question

so I followed this tutorial video (source)
to create a Java Enterprise Web Application and have ran into a problem. As this is pretty much the first time working with stuff like this for me I am clueless regarding how to solve this.
When trying to run the project I get an error saying "The module has not been deployed. See the server log for details." After some time trying to find out what was wrong I figured it is most likely the error I have in my "Student.java"-class. It says "cannot find symbol classTable. Create Subclass Create Test Class". What may be the problem here? I'm not sure what code would be relevant as I am a complete beginner to this, but all my files are exact copies of the source code-wise. Here is Student.java:
package com.joseph.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
/**

#Entity
#Table
#NamedQueries({#NamedQuery(name="Student.getAll",query="SELECT e FROM Student e")})
public class Student implements Serializable{
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column
private int studentId;
#Column
private String firstname;
#Column
private String lastname;
#Column
private int yearLevel;
public int getStudentId() {
return studentId;
}
public void setStudentId(int studentId) {
this.studentId = studentId;
}
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 int getYearLevel() {
return yearLevel;
}
public void setYearLevel(int yearLevel) {
this.yearLevel = yearLevel;
}
public Student(int studentId, String firstname, String lastname, int yearLevel) {
this.studentId = studentId;
this.firstname = firstname;
this.lastname = lastname;
this.yearLevel = yearLevel;
}
public Student(){}
}
