[HELP] using multiple value parameter in c:import tag

Question

I need to pass a multi-value parameter to a included page. e.g.
http://myhost/MyContext/dir1/page1.jsp?abc=value1&abc=value2/dir1/page1.jsp includes /dir2/page2.jsp, and would like to pass this multi-value parameter over, but change the name to xyz, some what like
<c:import url="/dir2/page2.jsp?xyz=value1&xyz=value2"/>The problem is that the number of values is not fix number, so I have to write some logic to iterate thru its parameter values. But the <c:import> tag body allows only simple listed <c:param> tags, it doesn't allow other logic/condition/iteration.
<!-- gives java.io.IOException: javax.servlet.jsp.JspException: The taglib validator rejected the page: "Illegal child tag in "c_rt:import" tag: "c:forEach" tag at runtime -->
<c:import url="/dir2/page2.jsp">
<c:forEach var="xyz" items="${paramValues.abc}">
<c:param name="xyz" value="${xyz}"/>
</c:forEach>
</c:import>{code}
I also tried <c:url> tag. The good news is that it supports jsp logic in body:
{code}<c:url var="url" value="/dir2/page2.jsp">
<c:forEach var="xyz" items="${paramValues.abc}">
<c:param name="xyz" value="${xyz}"/>
</c:forEach>
</c:url>
<c:out value="${url}"/>{code}but it prefixes the url with the current context:
{code}/MyContext/dir2/page2.jsp?xyz=value1&xyz=value2{code}
Now I run into a dead end. It seems the only way out is to use <% %> scriptlet to do my own url composite, which is pretty similar to <c:url> but avoid the context part.
Any suggestion?                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

Answer 1

out.println("<html>");
out.println("<head>");
out.println("<script language=\"JavaScript\">");
out.println("function altSubmit() {");
out.println("document.MyForm.action = \"Second.html\";");
out.println("document.MyForm.submit();");
out.println("}");
out.println("</script>");
out.println("</head>");
out.println("<body>");
My personal suggestion is to use follow the MVC (Model View Control) pattern where in you can write all your "html" part in a JSP.
Model -> Bean
View -> JSP
Control -> Servlet
