Hi akumar, What exactly were you expecting from the reverse mapping tool? Were you expecting that the @org.apache.openjpa.persistence.jdbc.Index annotations to be inserted into the generated java files? Or, were you expecting something else? You mentioned unique and non-unique keys... But, the primary key is detected correctly with the @Id annotation generation. I'm guessing you meant unique and non-unique indexes...
If you were expecting the @Index annotation, per the documentation, this annotation was really meant for the other direction. That is, it's used as a hint for OpenJPA when generating the database schema [1]: "..OpenJPA uses index information during schema generation to index the proper columns." And, even the Reverse Mapping tool is not meant to be the end-all game [2]: "..Examine the generated class, metadata, and mapping information, and modify it as necessary. Remember that the reverse mapping tool only provides a starting point, and you are free to make whatever modifications you like to the code it generates." Not saying that this process couldn't be enhanced as a feature request, but I don't think there's a bug in the processing. Good luck, Kevin [1] http://openjpa.apache.org/builds/latest/docs/docbook/manual.html#ref_guide_mapping_jpa_constraints [2] http://openjpa.apache.org/builds/latest/docs/docbook/manual.html#ref_guide_pc_reverse <http://openjpa.apache.org/builds/latest/docs/javadoc/org/apache/openjpa/persistence/jdbc/Index.html> On Thu, Dec 6, 2012 at 9:00 AM, anand213 <akumar...@bankofamerica.com>wrote: > Hi, > I am trying to reverse map beans by directly connecting to H2 DB.
