mysql-connector-java-3.1.10 fails to handle datatype "int unsigned" for JSTL

[dong_liu62]

I found that mysql-connector-java-3.1.10 returns wrong number for datatype "int unsigned" for JSTL sql tag.
I have used previous versions of connector on "int unsigned" without problem. However, when recently I need to redeploy the application to different machines with this version of connector, I got a huge number for the value of "1" stored as "int unsigned". After I changed all the datatype from "int unsigned" to straitforward "int", everything worked correctly.
The funny thing is, my JDBC code works fine. The only problem happens when I need to fetch the data using sql tags of JSTL, and display the value using JSTL c:out tag.

My environment:
JDK 1.5.0_04
MySQL 4.1.10
Tomcat 5.0.27
JSTL 1.0, Apache Standard Tag 1.0.3
mysql-connector-java-3.1.10
