id to load is required for loading
id to load is required for loading is a common error you may face while runtime .
I have faced this error while a bean call . A session bean of type entity is interacting with JPA project This can come due to several reasons based on your project .Some of them are as below:
If you invoke find method by passing null as primary key hibernate will throw the following exception to you .
If it is not set you might face the following exception .

org.hibernate.MappingException: Unknown entity:
Hi Guys ,
org.hibernate.MappingException: Unknown entity: is a common error you may face while runtime .
I have faced this error while a bean call . A session bean of type entity . This can come due to several reasons based on your project .Some of them are as below:
1.In your persistence.xml you need to dd that particular class like as below :
<class>model.Account</class>
If it is not set you might face the following exception .

'hibernate.dialect' not set
Hi Guys ,
'hibernate.dialect' not set is a common error you may face while deploying your EAR . This can come due to several reasons based on your project .
Check the below stack trace ..
To find the root cause you need to check the following :
1. make sure your bean's persistance.xml is having the following entry :
<persistence-unit name="your unit name" transaction-type="JTA">
2. make sure your jpa project's is having the same entry .
<persistence-unit name="your unit name" transaction-type="JTA">
3. make sure your bean is using the same unit name .
@PersistenceContext(unitName = "ConsultingJPA")
If it is not set you might face the following exception .
Caused by: org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set
