What's the EJB-QL syntax for doing BigDecimal comparison in ejb-finder methods?
I've a Entity Bean (Order) with CMP field of type BigDecimal (Price). The JBOSS CMP engine maps it to Oracle DB with column type of Number(38,15). My ejb-finder method is to find purchase orders with price greater than a given decimal number. I've tried the EJB-QL statement:
SELECT DISTINCT OBJECT (o) FROM OrderSchema AS o WHERE o.price >= ?1
with input parameter of either type java.math.BigDecimal or double. But I always get the following parsing exception:
org.jboss.deployment.DeploymentException: Could not deploy file:/home/jboss-3.0.0RC1/server/default/deploy/mex001.jar; - nested throwable is:
boss.deployment.DeploymentException: Error compiling ejbql; - nested throw
s: org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "o.price" a

Was expecting one of:

"CONCAT" ...

It looks like the parser couldn't recognize "o.price" as a floating point value. What's the right EJB-QL syntax for non-basic-type CMP fields like o.price of type BigDecimal here? I'm using JBOSS 3.0 RC1. Any help is appreciated.
