Hi,

no long talking - here are the POJOs I want to map:

Code:
public class StaffCategory extends Category<StaffCategory> {
   
   private StaffCategory parent;
   
   private Set<StaffCategory> children;
   
   private Set<StaffResource> staffResources;
   
        // ...


As you can see StaffCategory has associations to StaffResource. Here are the hibernate mappings:

Code:
<class name="StaffCategory">
   <id name="id"><generator class="native" /></id>
   <property name="name" />
   <many-to-one name="parent" />
   <set name="children" inverse="true" cascade="all">
      <key column="parent"/>
      <one-to-many class="StaffCategory"/>
   </set>
   <set name="staffResources" table="StaffCategory2StaffResource">
      <key column="staffCategoryId"/>
      <many-to-many
         column="staffResourceId"
         class="de.mathiasewald.projektseminar.data.bo.external.StaffResource"
      />
   </set>
</class>

<class name="StaffResource">
   <id name="id"><generator class="native" /></id>
   <property name="name"/>
   <many-to-one name="address" cascade="all"/>   
   <property name="email"/>
   <property name="landline"/>   
      
   <joined-subclass name="Freelancer">
      <key column="freelancerId"/>
      <property name="firstName"/>
      <property name="email"/>
      <property name="mobile"/>
   </joined-subclass>
   
   <joined-subclass name="Agency">
      <key column="agencyId"/>
   </joined-subclass>
</class>


Some where in my code I want to get a java.util.List of all StaffCategories that know a certain StaffResource:

Code:
categories = (List<StaffCategory>)s.createCriteria(StaffCategory.class)
   .add(Restrictions.in("staffResources", new StaffResource[] {staffResource})).list();


As a result I get a big fat stack trace:

What does this "java.sql.SQLException: No value specified for parameter 1" mean an how do I fix it? I learned the basics of hibernate in approx. 2 days so I am quite helpless here.

Any help appreciated!
