the statement needs to appear underneath your root element:

<xsp:page>
 <xsp:logic>
  static private int counter = 0;
 </xsp:logic>
 <page>
  <xsp:logic>
   String id = request.getParameter("id");
  </xsp:logic>
 </page>
</xsp:page>

xsp:logic elements outside of your root element are treated as class
variables - they don't appear in a method. it's like writing:

public class test {

  static private int counter = 0;
  String id = request.getParameter("id");

}

even if request was in scope at the time, it's forbidden for statements to
appear outside of a method or static initializer block.
