Character to numeric conversion error on java.lang.Double

Hi,
I know it's maybe more a hibernate question, but we are using Spring's HibernateTemplate , so maybe you can help.
I have a quite simple configuration (and problem):
In the POJO object (InputTransactionLNC.java) there are java.lang.Double types. I'm using Informix database, where the attributes in table aro of FLOAT types.
When I try to save an instance, where these Double are filled,
I got an Char to numeric SQLException (see below).

I tried to map the double attribute to java.lang.Double/didn't specify the type, but neither of those works (ends up with exception).

any ideas? thank you
