You can put your parameters in a map with the parameter name as the key and the parameter value as the value. i.e. if you want to link to
myJsp.jsp?x=4&y=2:
1) create your map somewhere
<%
HashMap paramMap=new HashMap();
paramMap.put("x", "4");
paramMap.put("y", "2");
%>
2) create your link
<html:link page="myJsp.jsp" name="paramMap" />
I haven't done this exactly so the syntax may not be exactly right on the link name. However, you can always use both name and property to get a property of a bean that is declared as a Map. i.e. have a bean with a getter
public Map getLinkParams() { return linkParams; }
I've used this in the past, and it works great.
