To write the size of collection object or array,
you can <bean:size id="size" name="thecollection"/>
and write with <bean:write name="size"/>.
The "size" bean can also be used with the tag
<logic:notEqual name="size" value="0">
...
</logic:notEqual>
In the case of toString, if you don't specify a property
attribute in the tag <bean:write>, the output is the toString
of the object, like the above example.
This may help to avoid scriptlet in the JSP in some
cases.
