I beleive primary keys must be Serializalble. Try using an Integer object
instead.

Subject: OR mapping with Oracle
Hi guys,
Coupld you please help with teh below problem? I haven't found any solution
yet.
I am using Orion 1.3.8, Oracle 8.1.5.
I want to use a Compound object as a primary key to my CMP Entity Bean.
This PK class has one public member key of int datatype.
The PK class:
public class ProductPK implements java.io.Serializable {
public int key; //this should be mapped to a column in the Oracle
bean table
public ProductPK(int key) {
this.key=key;
}
}
I edited orion-ejb-jar.xml to map the primary key field (this is necessary I
think, because Oracle maps Serializable objects to blobs that cannot be part
of primary keys):
<primkey-mapping>
<cmp-field-mapping name="key">
<fields>
<cmp-field-mapping name="key" persistence-name="key" />
</fields>
</cmp-field-mapping>
</primkey-mapping>
The error message I always got:
Auto-deploying beantest-ejb.jar (orion-ejb-jar.xml had been updated since
the previous deployment)... ProductRemote_EntityBeanWrapper0.java:781:
Incompatible type for method. Can't convert beantest.ejb.ProductPK to int.
statement.setInt(4, object.key);
^
ProductHome_EntityHomeWrapper7.java:388: Incompatible type for method. Can't
convert beantest.ejb.ProductPK to int.
statement.setInt(4, response.object.key);
^
2 errors
Error compiling file:/E:/Java/BeanTest/build/beantest/beantest-ejb.jar:
Syntax error in source
I've already looked at OrionSupport and the mailing list archive, but found
no solution ti this problem.
Any idea would be gratefully appreciated!
Tibor
