When using digester rules xml file, digester connot assign date, int or foalt setter fields type to a bean.
Summary: When using digester rules xml file, digester connot
assign date, int or foalt setter fields type to a bean.
Product: Commons
Version: 1.5 Final
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: Normal
Priority: Other
Component: Digester
AssignedTo: commons-dev@jakarta.apache.org
ReportedBy: pierre.lessard@promutuel.ca
When using digester rules xml file, digester connot assign date, int or foalt
setter fields type to a bean. Look at the sample code attached below.
Meanwhile, when defining rules programmatically, it works, see Digester Driver.
The setters which are not working are setId(long), setDate(java.sql.Date) and
setPrice(float) on the Magazine class.
For more info, please email-me.
