I really can't seem to figure this out.
I'm going to post my source code:
UserInterest
Code:
package com.tkassembled.data ;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import org.red5.io.amf3.IDataInput;
import org.red5.io.amf3.IDataOutput;
import org.red5.io.amf3.IExternalizable;
/**
*
*/
@Entity @Table(name = "userinterest")
public class UserInterest implements IExternalizable
{
/**
* @private
*/
@Id @GeneratedValue @Column(name = "id")
private Integer id;
/**
* @private
*/
@Column(name = "realm")
private Integer realm = 999;
/**
* @private
*/
@Column(name = "level")
private Integer level = 0;
/**
* @private
*/
@Column(name = "years")
private Integer years = 0;
/**
* Contains values for a User's realms of interest.
*/
public UserInterest()
{
}
/**
* @see IExternalizable
*/
public void readExternal(IDataInput input)
{
this.id = input.readInt();
this.realm = input.readInt();
this.level = input.readInt();
this.years = input.readInt();
}
/**
* @see IExternalizable
*/
public void writeExternal(IDataOutput output)
{
output.writeInt(this.id);
output.writeInt(this.realm);
output.writeInt(this.level);
output.writeInt(this.years);
}
public Integer getId() {return this.id;}
public void setId(Integer id) { this.id = id; }
public Integer getRealm() { return realm; }
public void setRealm(Integer realm) { this.realm = realm; }
public Integer getLevel() { return level; }
public void setLevel(Integer level) { this.level = level; }
public Integer getYears() { return years; }
public void setYears(Integer years) { this.years = years; }
}
Again, this is an entry in a collection that I've defined in my User class as so:
Code:
@OneToMany
@JoinTable(
name="users_userinterests",
joinColumns = @JoinColumn(name = "user_id", unique = false),
inverseJoinColumns = @JoinColumn(name = "interest_id", unique = false)
)
And, for kicks, here's my Hibernate output and errors:

Help is extremely appreciated in this. I'm totally hung up on development until I can get this done. Looks like it's gonna be a long day today and it's already 6pm :/
