I can specified two field to primary key

[Richard Banks]

Yes, no problems at all.

Just mark each of the attributes in the primary key as key="primary".

For example:

  <class name="A" table="TableA" database="DB">
    <attribute name="AKey1" column="KeyCol1" key="primary" />
    <attribute name="AKey2" column="KeyCol2" key="primary" />
    <attribute name="Data1" column="Data1"/>
    <attribute name="Data2" column="Data2"/>
    <attribute name="CreatedDate" column="Created" timestamp="true" />
    <attribute name="ModifiedDate" column="Modified" timestamp="true" />
  </class>
