Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
Hi there,

I have a bug in my software and I need help.

It's a java software that uses mysql and hibernate. The mapping is done via hbn files, not with annotation.
The problem occurs when trying to store a many-to-one relation/ bidirectional relationship.

The exeption that occurs:
com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'IStock_ID' cannot be null

The software architecture:
java 1.6 code running locally on Ubuntu 12.04 LTS (within eclipse) and it connects to a remote mysql database.

How to apply:
Please only apply if you are experienced in hibernate, java and mysql.

Please tell me what experiences you've had with the mentioned technologies and tell me what software I should install in order to give you remote access to my Ubuntu machine. We would speak during the bug fixing via Google hangout (in English) and I would take a live view on the changes you are doing.

Thanks and cheers!
