PropertyAccessException: exception setting property

kaylanx · **Posted:** Fri Dec 01, 2006 1:09 pm

I have an object with RedemptionPenaltyValue with a property ...

Code:

private double year1Percentage

In the column on the table that this maps to (oracle10g) it is NUMBER(7,3)

I get this exception when the column is null.....

Code:

org.springframework.orm.hibernate3.HibernateSystemException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.hidden.value.RedemptionPenaltyValue.setYear1Percentage; nested exception is org.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.hidden.value.RedemptionPenaltyValue.setYear1Percentage
Caused by: org.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.hidden.value.RedemptionPenaltyValue.setYear1Percentage
   at org.hibernate.tuple.PojoEntityTuplizer.setPropertyValuesWithOptimizer(PojoEntityTuplizer.java:215)

   at org.hibernate.engine.TwoPhaseLoad.initializeEntity(TwoPhaseLoad.java:126)

....<snip/>

I have figured out that if I change the year1Percentage property (and its getters and setters etc) to a java.lang.Double then it works. Any ideas why???

This is a bit annoying as this is existing code that we are converting from JDBC to Hibernate, and I dont really want to go and change all doubles to Doubles etc.

Thanks

Andy.

This is because your code has a primitive double, not DOUBLE, hence you can't have nulls. Primitives can only be used with not-null fields.

Thanks thought that might be the case.
