Creating other public methods in entity class

Question

I have an Entity class

    @Entity
    @Table(name = "rule")
    public class Rule implements Cloneable, Serializable, IPojoGenEntity, IRule, SequencedEntity {

    private String name;

    private Service service;

    //getter .. setter for service and name

      public String getServiceName() {
        return (this.service.getName());
      }

     public void setServiceName(String servicename) {
       this.service.setName(servicename);
     }

    }

I am getting exception for getting service name through RulClass object

public String getServiceName() {
        return (this.service.getName());
      }

Stack Trace

Caused by: com.ibm.db2.jcc.b.SqlException: "RULE0_.SERVICENAME" is not valid in the context where it is used.

Can we use such getter and setter in an entity class?

I am using hibernate, spring, DB2, IBM WebSphere

You should either make it @Transient as it was mentioned if you don't want to store it

OR

Define @javax.persistence.Column(name = "service_id") field annotation for the getter to let hibernate know which column to use.

OR

Rename DB to have the service field "SERVICENAME" to use default column name

There is the Transient annotation to tell Hibernate to ignore a field. So:

@Transient
private Service service;

From very similar SO question: Make hibernate ignore class variables that are not mapped.

No No. I want to save this service field. I am just getting its (service) members in Rule class also. – Muhammad Imran Tariq Feb 12 '13 at 07:46
What does your schema look like? – SimonC Feb 12 '13 at 07:48
Rule class will have two members. name and Service. Service will have only name – Muhammad Imran Tariq Feb 12 '13 at 07:55

As serviceName was not a member of Rule class so there is a problem with method name. Name cannot be like

getServiceName
setServiceName

rather it should be something other than get or set prefix

fetchServiceName
addServiceName
