Hi all,

I am using hibernate annotations and am not using hbm mapping files. When I insert and save data in DB through my persistence class 'UserResume', I get following error


Exception in thread "main" org.hibernate.MappingException: Unknown entity: candidate.UserResume

As far as i know we get this error when no mapping file is found but as I am using annotations, I dont require hbm.xml for UserResume.java.
Please help me.....

Could paste in your UserResume class?

Regards,
Søren

code for my mapping is:

<mapping class="candidate.UserResume" />


and my UserResume class is below:


package candidate;

import java.sql.Blob;
import org.hibernate.annotations.*;
import javax.persistence.Column;
import javax.persistence.Lob;
import javax.persistence.Table;


@Entity
@Table(name = "user_resume")
public class UserResume {

private String resumeId;
private Blob resumeBlob;
private String userId;

@Column(name = "resume_blob")
@Lob
public Blob getResumeBlob() {
return resumeBlob;
}
public void setResumeBlob(Blob resumeBlob) {
this.resumeBlob = resumeBlob;
}

@Column(name = "resume_id", unique = true, nullable = false, insertable = true, updatable = false)
public String getResumeId() {
return resumeId;
}
public void setResumeId(String resumeId) {
this.resumeId = resumeId;
}

@Column(name = "user_id", unique = true, nullable = false, insertable = true, updatable = false)
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}

}

I got it....

I was using Entity from package org.hibernate.annotations whereas I was supposed to use it from package javax.persistence.

thanks anyways.
