One to One Mapping of Composite Keys ------------------------------------ Key: HHH-6638 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6638 Project: Hibernate Core Issue Type: Bug Components: annotations, core, entity-manager, query-hql Affects Versions: 3.5.5 Environment: Below are the list of jars included in the classpath. hibernate-commons-annotations-3.2.0.Final.jar hibernate-annotations-3.5.5-Final.jar hibernate-core-3.5.5-Final.jar hibernate-entitymanager-3.5.5-Final.jar hibernate-jpa-2.0-api-1.0.0.Final.jar log4j-1.2.14.jar dom4j-1.6.1.jar slf4j-api-1.5.6.jar slf4j-log4j12-1.5.6.jar javaassist-3.9.0.GA.jar derbyclient.jar commons-collections-3.2.1.jar jta-1.1.jar antlr-2.7.6.jar The database used is derby. Below is the table create scripts CREATE TABLE VYA6CPP ( A6VN9K VARCHAR(9), A6VN8K VARCHAR(8), A6J2CD VARCHAR(20), PRIMARY KEY(A6VN9K, A6VN8K) ) CREATE TABLE MAMAM1 ( M1VIN1 VARCHAR(9), M1VIN2 VARCHAR(8), M1SHPR VARCHAR(4), PRIMARY KEY(M1VIN1, M1VIN2), FOREIGN KEY(M1VIN1, M1VIN2) REFERENCES VYA6CPP(A6VN9K, A6VN8K) ) Reporter: Srikanth Rajkumar Attachments: src.zip When the attached source is executed, i am getting the below error. Hibernate is not able to map composite keys if the keys names are different.
