The first thing I would try is taking everything out of the
<sql:update> except the query string itself and the <sql:param>
element, so that you're left with:
<sql:update dataSource="jdbc/zobarenk">
insert into test_table (testnumber_id) values (?)
<sql:param value="${param.testnumber}"/>
</sql:update>
