jahlborn commented on HBX-964:
------------------------------
no patch, but here's a simple algorithm:
1. xor together the hashes of each property name -> hash1
2. xor together the hashes of each property type -> hash2
3. construct serialVersionUID as long with hash1 as high 32 bits and hash2 as low 32 bits
add serialVersionUID to entity classes
--------------------------------------
Key: HBX-964
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-964
Project: Hibernate Tools
Issue Type: Improvement
Components: hbm2java
Affects Versions: 3.2beta10
Reporter: Dan Allen
Priority: Minor
Attachments: HBX-964-v1.txt
Original Estimate: 5 minutes
Remaining Estimate: 5 minutes
The serialVersionUID is recommended for classes that implement java.io.Serializable. The
hbm2java task should either set the serialVersionUID to 1L or automatically generate a
value. I prefer setting it to 1L because it is easy and it will work, but if you feel
motivated, you can look at what Eclipse does to generate this value from the class
signature.
I have included a patch that just sets it to 1L.
