Hi,

my project involves struts,springs and hibernate. i am new to these techs.

i created a small new functionality in project to understand the complete flow of project . To get the overall idea of project and complete mechanisam i used strut-config.xml,mvc pattern and orther concepts of hibernate. in this process, i am stuck with an error while saving the hibernate object . i used the existing methods , formbeans,jsp etc to fetch the date from front end and wrote a new function to save the date on to a new table in database using pojo and hbm files.however when it comes to saving data i used same method available in the code.
below i mention the exception while saving the object using hibernate saveobject.

exception was :

HIBER TEMP: org.springframework.orm.hibernate3.HibernateTemplate@ad4bb0
exception isorg.springframework.orm.hibernate3.HibernateSystemException: Unknown entity: com.syntel.sb.appl.bo.vendor.SBBillingAddress;
nested exception is org.hibernate.MappingException: Unknown entity: com.syntel.sb.appl.bo.vendor.SBBillingAddress

function used to save in hibernate was :

public void saveObject(Object o)
{
System.out.println("HIBER TEMP: " + getHibernateTemplate());
try{
getHibernateTemplate().save(o);
}
catch(Exception e)
{
System.out.println(" exception is"+e);
}
}


kindly suggest me to troubleshoot this error in detail.
Thanks in Advance

Please UseCodeTags. I would start with not using HIbernateTemplate. Spring now advises against the use of this. Please follow the current best practices as outlined here:
http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/orm.html#orm-hibernate

Are you using annotations or xml for your hibernate mapping? If you are using annotation make sure you are importing javax.persistence.Entity and not org.hibernate.annotations.Entity on your SBBillingAddress class.

Thanks Bill Gorder. problem got solved. the poblem was that I was using wrong mapping file and replaced with new one.

Hi ,

After adding the mapping file at application contex hibernate file, my entire web application was down.

if i remove the newly added mapping file, the application was working fine with previous post error "no entity found" .

after a deep work with tag libraries , and jars my application was running good with new functionality along with mapping file inlcuded

day before yesterday, i simply added 2 new columns in my database, and so updated corresponding hbm files and POJO files ,action classes,forms,serviceimple .

Now my application was down again. with below errors.
