Hi Rajan,
Something like that is alos happening with me as well. I have created process and they are perfectly working fine, but I really don't c any of them in my DB. There is only one entity that I have created is available with data in db.
Properties in persistence.xml
<
property name="javax.persistence.jdbc.driver" value="org.h2.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:h2:tcp://localhost/~/test;DB_CLOSE_DELAY=-1;MVCC=TRUE" />
<property name="javax.persistence.jdbc.user" value="sa" />
<property name="javax.persistence.jdbc.password" value="" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.hbm2ddl.auto" value="create" />
and I don't see test.h2.db being created as well.
