Hibernate one-to-many Mapping Problem - org/odmg/DSet

[gibelium]

hello again...

i try mapping my orders collection in my customer class via hibernate one-to-many association. but get following error. everything from spring dependencies is included in my classpath, hibernate2.jar as well.

java.lang.ExceptionInInitializerError
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [applicationContext.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/odmg/DSet

the customer class holds simply a java.util.Set with the customers. both tables workung fine without mapping them together.

the interesting part of the mapping file is the following:

<set
    	name="orders">
       	<key column="CUSTOMER_ID"/>
        <one-to-many class="Order"/>
    </set>

any idea, why hibernate searches for a standard java Set and gives a NoClassDefFoundError?

You need odmg.jar on your classpath, plus make sure you only have one cpoy of hibernate and odmg on your classpath.

*yeah* it works...

i copied the odmg.jar from the spring 1.01 with dependencies distribution, because it lacks in the 1.2 distribution...

thanx for the fast help...
