It is very easy to generate code using Hbm2java, which is much easier to use than the Schemaexport (profile to database) provided by Hibernate. I don't know what the author is doing, writing a schemaexport so hard ... 1. Before the beginning of the preparation 1.1 prepare Hibernate-2.1.6.zip 1.2 prepare Hibernate-extensions-2.1.2.zip 1.3 prepare Logging-log4j-1.2.9.zip 1.4 to put the relevant. jar Files all Duplicate The Lib directory under the engineering directory 1.5 knows how to use ant. Read my article "very simple Ant file" 2. Create the Engineering directory and file structure as follows
Payment <dir>|-src <dir>|-hbm <dir> |-payment <dir> |-payment.hbm.xml|-classes <dir>|-lib <dir>|-build.xml|- Hibernate.codegen.xml|-log4j.properties3.
