I'm not an expert, but I suspect that the resource config parameters
will act like javabean setters.  So you should be able to specify
something like:
 
<parameter>
   <name>validationQuery</name>
   <value>SELECT 1</value>
</parameter>
<parameter>
   <name>testOnBorrow</name>
   <value>true</value>
</parameter>
