The README file in the 2.0 beta now includes a change log so please check read this when you download new builds.
In the latest build ...
[b483] Changed some default Java type mappings on importing a schema. JDBC types BIGINT, NUMERIC, DECIMAL with scale of zero (i.e. no decimal places) now only get mapped to int or long (or their object equivalents). JDBC types BIGINT, NUMERIC with a non-zero scale (i.e. does have decimal places) now always get mapped to the java.math.BigDecimal type.
[b483] When generating CMP finders for columns that are of type java.math.BigDecimal the EJB-QL finder definitions use the float primitive type since EJB-QL does not support java.math.BigDecimal. The generated DAO implementation code takes care of conversion from BigDecimal to float when the finders are called so this change is transparent to the user.
