Subject MariaDB LocalDate field casting issue
Date Sat, 29 Apr 2017 21:07:49 GMT
Hi,

I'm having an issue using a LocalDate field in my MariaDB table.

I'm using mysql  Ver 15.1 Distrib 10.0.30-MariaDB, for debian-linux-gnu 
(x86_64) using readline 5.2

The table is defined as the following...

<?xml version="1.0" encoding="utf-8"?>
<obj-attribute name="defaultTimeZone" type="java.lang.String" 
db-attribute-path="defaultTimeZone"/>
<obj-attribute name="expireDate" type="java.time.LocalDate" 
db-attribute-path="expireDate"/>
<obj-attribute name="maintenanceDate" type="java.time.LocalDate" 
db-attribute-path="maintenanceDate"/>
<obj-attribute name="name" type="java.lang.String" 
db-attribute-path="name"/>
<obj-attribute name="status" type="short" db-attribute-path="statusID"/>

The code generating the error is the following ...

             Client client = context.newObject(Client.class);
             client.setExpireDate(LocalDate.now());
             client.setMaintenanceDate(LocalDate.now());
client.setDefaultTimeZone(TimeZone.getDefault().getID());
             client.setName(CLIENT_TEMPLATE_NAME);
client.setStatus(EnumSimpleStatus.STATUS_INACTIVE.toShort());
             context.commitChanges();

Upon execution of this code I'm getting

java.sql.SQLException: Cannot convert class [B to SQL type requested due 
to java.lang.ClassCastException - [B cannot be cast to java.util.Date

I'm not sure why I'm getting the casting error.  Is there some 
underlying version compatibility?

Thanks,

Andrew
