Pinaki Poddar commented on OPENJPA-340:
---------------------------------------

Currently partial support exists. Unique constraints can be specified at @Table annotation is processed.

For example, given 
  
@Entity
@Table(name="Person",uniqueConstraints=@UniqueConstraint(columnNames={"first","last"}))
public class Person {
	@Id
	private long id;
	private String first;
	private String last;
}

will generate following table schema
CREATE TABLE Person (id BIGINT NOT NULL, first VARCHAR(255), last VARCHAR(255), PRIMARY KEY (id), UNIQUE (first, last))

> OpenJPA ignores @UniqueConstraint annotations (and the corresponding XML declaration) when generating database schemas. This should be rectified.
> A workaround is to set the -ignoreErrors flag to true when running mappingtool, which will let schema creation continue despite the error.
