Hi all, I am trying to insert a record into database table using Hibernate and I get the following exception, when I tested it using JUnit.

(BasicPropertyAccessor.java:66): - expected type: java.lang.String, actual value: java.lang.String

Hibernate version: 3.0.5
database: Oracle9i Enterprise Edition Release 9.2.0.1.0
JDK 1.4.2.08
websphere 5.1.2

Exception :

}

Code:

HibernateTemplate template = getHibernateTemplate();
Class clazz = OrgRoleTyp.class;
ClassMetadata classMetadata = template.getSessionFactory().getClassMetadata(clazz);
classMetadata.setPropertyValue(clazz,"orgRoleTypNm","APradesh",EntityMode.POJO);
template.save(clazz);


Could some one please let me know what is the cause for this exception.

Thanks in adv.

Could it be because of the 'type="java.lang.String"' attribute? The ref docs say to use hibernate types, not the java types, so 'type="string"' is correct. However I've seen people post mappings using 'type="java.lang.Integer"' and it seems to work for them. I've only ever used the type="string"/type="integer" way of doing things, so this is just a guess...

what are you trying to do here ?
looks like you trying to set a property on java.lang.Class object.

I am trying to set the orgRoleTypNm property of OrgRoleTyp Object , which is a Pojo object.

where is the instance of this pojo ? cannot see it in the code.
Why can't you just call the setter method on the pojo instance?

Yes, you are correct, but I am trying this code not specific to one pojo object. Later I would set - Class clazz = OrgRoleTyp.class; dynamically, so that this code works for any pojo Object.

Yes but hibernate needs the pojo instance not the class object.

classMetadata.setPropertyValue(clazz,"orgRoleTypNm","APradesh",EntityMode.POJO);

This method expects the first parameter to be an instance of a mapped entity not a class object.

I think you are correct, I need to find a way to dynamically get a pojo object and pass it to classMetadata.setPropertyValue method.

Thanks

please rate also if a post helped.

Sure, I was just about to do it... :) Thanks for correcting my mistake.

I will come back again after I get any solution, in mean while if some one can suggest me that would be of great help.

Thx

Try something like this:

Yes, Finallly I am able to insert successfully and if I pass OrgRoleTyp.class dynamically, I would make the following code working for any pojo object. :)

HibernateTemplate template = getHibernateTemplate();
Class clazz = OrgRoleTyp.class;
Object obj = clazz.newInstance();
ClassMetadata classMetadata = template.getSessionFactory().getClassMetadata(clazz);
classMetadata.setPropertyValue(obj,"orgRoleTypNm","APradesh",EntityMode.POJO);
template.save(obj);

Thank you all

Some corrections to the my previous post :D

Yes, Finallly I am able to insert successfully and if I pass OrgRoleTyp.class,orgRoleTypNm and APradesh dynamically, I would make the following code working for any pojo object. :)

HibernateTemplate template = getHibernateTemplate();
Class clazz = OrgRoleTyp.class;
Object obj = clazz.newInstance();
ClassMetadata classMetadata = template.getSessionFactory().getClassMetadata(clazz);
classMetadata.setPropertyValue(obj,"orgRoleTypNm","APradesh",EntityMode.POJO);
template.save(obj);

Thank you all
