Hi,

I have a table "xpackage" and a table "xclass".
"xclass" has a primary key (xclassname,xpackageid).

I generated the DAOs from the mappingfiles. So far everything seems to be fine.

I don't know how to set the primarykey of the xclass. I get a net.sf.hibernate.MappingException: Unknown entity class: model.genDAO.Xclass

What does that mean? Is something wrong with my db-tables or is it caused by my rubbish javacode? ;)

My xclass mapping looks like that:
<hibernate-mapping package="model.genDAO">
<class
name="Xclass"
table="xclass"
>
<composite-id name="PK" class="XclassPK">
<key-property
name="name"
column="name"
type="string"
/>
<key-many-to-one
name="package"
class="Xpackage"
column="package"
/>
</composite-id>

<property
...
</class>
</hibernate-mapping>

How can the primary key of the table xclass be set???

I tried it with:
...
try {
_RootDAO.initialize();

XpackageDAO xpdao = new XpackageDAO();
XclassDAO dao = new XclassDAO();
Xclass xc = new Xclass();
XclassPK pk = new XclassPK();

pk.setName(xclass.getName());
pk.setPackage(xpdao.get(packageID));

Transaction tx = dao.beginTransaction(dao.getSession());

xc.setIsabstract(xclass.isAbstract());
xc.setIsinterface(xclass.isInterface());
dao.save(xc); // <-- here, the exception is thrown.

} catch (HibernateException e) {
e.printStackTrace();
...

Thanks in advance,
Kurt

Unknown entity class means that the session factory has not been configured with the mapping for the class you are supplying to the session.

Please post your hibernate configuration file, the hibernate version being used, and any other third-party (e.g. Spring) frameworks that may be involved if you need further help. For a full list of requirements for solving the typical problems, please see HowToAskForHelp

I found the reason why the entity class could not be found. I feel ashamed... In the hibernate.cfg.xml I commented the xlass out. I forgot that.
Thanks CollinL.
