Using request.getParameterValues for Query???

I am working on a JSP and I have come to an obstacle...

I need to get the values from a list box from an HTML form on the previous JSP...with these values I need to loop through them so as to use them for my SQL server..

I hope that I am explaining well enough...

I know that I can use the request.getParametersValues(), but what I do not know is how to loop through the array so as to extract the values, and then how to use them in my SQL Server query (view)??????????????

I am fairly new to JSP & JAVA...so any assistance will be a GREAT help!!!

Thank you!!
