[#5666] - Dynamic query not working on Jasperserver

I have developed a report using Ireport 4.5.0 which used a dynamic query (query with keyword WHERE using a parameter).
That report works fines in IReport but don't work in JasperServer 4.5.0
The aim of the parameter is to filter data by date.
The report has Three parameter
- type_de_sonde (String)
- Start_date (String : date in format YYYYMMDD)
- Stop_date (String : date in format YYYYMMDD)
The two date parameter are used to define a specific date or a default date base on current date.
