Spring with Hibernate JPA using Virtual database columns not working -

i have scenario have entity variable (say x) points virtual column in db. used variable x project data onto ui or , don't want inserted or updated when iam updating or creating entity object.

for achieved have introduced insertable , updatable false shown below

  @column(name = "virtual_column_name_in_db", length = 4000, updatable = false, insertable = false)   private string x; 

i have introduced associated getters , setters well.

with annotations introduced, expected variable x not included part of insert or update opeartions

but, not case , see coming in insert , update operations, inturn causing me have db error below

org.springframework.orm.hibernate3.hibernatejdbcexception: jdbc exception on hibernate data access: sqlexception sql [n/a]; sql state [99999]; error code [54017]; ora-54017: update operation disallowed on virtual columns ; nested exception org.hibernate.exception.genericjdbcexception: ora-54017: update operation disallowed on virtual columns     @ org.springframework.orm.hibernate3.sessionfactoryutils.converthibernateaccessexception(sessionfactoryutils.java:651)     @ org.springframework.orm.jpa.vendor.hibernatejpadialect.translateexceptionifpossible(hibernatejpadialect.java:105) 

please let me know how use virtual columns in spring based application hibernate jpa

have tried @transient annotation? supposed that: "this annotation specifies property or field not persistent. used annotate property or field of entity class, mapped superclass, or embeddable class."
