First of all thank you very much for your reply ....

In this case , I should have a java code that builds query string based on a
loop that goes through the 2-D array , correct ?
Any tips or reading material is extremely apprecited...

JSTL (JSP Standard Tag Library) and JSF (Java Server Faces) to the rescue,
specifically, EL (expression language).

<c:forEach items="${outer}" var="${thing}" >
   <a href="thetarget.jsp?Col2=${thing.b};Col3=${thing.c}">
     <c:out value="${thing.a}" />
   </a>
   <br />
</c:forEach>

or some variation thereof. Nowadays, thanks to JSF, we'd prefer the enhanced
EL, that usually uses an octothorpe instead of a dollar sign to indicate an
expression:

     <h:outputText value="#{thing.a}" />
