Issue

• Getting below error in DEV Server when using db2cc4 driver.In my local JBOSS server I am not getting any exception. Could you let me know if you have any idea on this?

• Both dev and QA points to same database and the column name is valid.

• Exception retrieving data from result set.

• Further to update on this issue in my local server I have db2cc.jar and in my Dev server I have db2cc4.jar.Query is executing fine if I have db2cc.jar but throwing the above error if I have db2cc4.jar.
• We have issue in hibernate JPA implementation Entity/NativeQuery mapping.
• We need to manage some cases when an entity class has many more properties that the associated SQL statement's select list but in such case we get below exception:

java.sql.SQLException: Invalid column name

• We noticed that Hibernate JPA 2.0 implementation, differently from EclipseLink, mandate that EVERY property in the entity class, that has been annotated with @Column, MUST be populated by a native query, thus the SQL statement's select list MUST include EVERY column specified in the entity class. Is that true? Can this behaviour be modified perhaps using a property in the persistence.xml file?
