Hi Daniel,
    You'll need to use a javaType="java.math.BigDecimal" for your 
INTEGER/BIGINT field (with canBeNull="true").  This is actually the only 
non-primitive datatype for numbers that is supported in JDBC by its own 
setXxx() methods (in the java.sql.PreparedStatement interface) and getXxx() 
methods (in the java.sql.ResultSet interface) - which is my guess as to why 
DODS doesn't support it (yet).  Especially in the case of a BIGINT, it 
sounds like this would be the javaType you'd want.

Regards,
Mike.

P.S. to the DODS developers:  Are there any plans for extending the DODS 
code templates to support the use of the Integer, Long, Float, or Double 
wrapper classes for the javaType attribute, at some point in the future?
