DbUnit

This is my table definition.
create table example(name varchar(25),id int(50) not null,m1 tinyint(1))
This is my XML file

<?xml version='1.0' encoding='UTF-8'?>
<dataset>
<table name="example">
<column>name</column>
<column>id</column>
<column>m1</column>
<row>
<value>robi</value>
<value>1</value>
<value></value>
</row>
</table>
</dataset>

while populating data dbunit expect a value for m1, but it is a nullable
column.Only for type tinyint dbunit expect a value even if it is a nullable
column. But i want to populate data without a value for the column m1.

TestCase:

public void testIt() throws Exception{
IDataSet ds = new
XmlDataSet(getClass().getResourceAsStream("dataset.xml"));
IDatabaseConnection dbConn =
MySqlTinyintTest.getDbUnitConnection();
DatabaseOperation.INSERT.execute(dbConn, ds);
}

Thanks to kalpana for reporting this one.
