IBATIS 2 SQL Map: LIKE + '%'

Jumpa 1 isu dengan SQL Mapping apabila cuba gunakan LIKE dengan '%' dalam SQL Map framework IBATIS 2 

<![CDATA[
function matchwo(a,b)
{
if (a < b && a < 0) then
  {
  return 1;
  }
else
  {
  return 0;
  }
}
]]>

Notes on CDATA sections:

• A CDATA section cannot contain the string "]]>". 
• Nested CDATA sections are not allowed.
• The "]]>" that marks the end of the CDATA section cannot contain spaces or line breaks.
