Hi.
I have not bin able to solve this problem.
It's all about @OneToMany - @ManyToOne relations in entitys.
As long as I use my entitys in a session bean, there is no problem.
But, when I try to use them as objects in a webservice I'll get plenty of
errors.
I've tried serveral methods with @XmlRootElement and @XmlTransient with no
luck.
Using the webservice I'm able to create objects, connect objects, but when I
try to recive an object from the db it allways gives errors.
So, if you have anything, any tips or other questions, please let me know.
I've bin strugling with this for over a year now.
Best Regards
Kristian
