> I need to put in jsp file many times a set of HTML tags which are

> <input type="radio" name="English" value="0" checked>
> <input type="radio" name="English" value="1">
> <input type="radio" name="English" value="2">
> <input type="radio" name="English" value="3">
>
> <input type="radio" name="Otherlanguage" value="0" checked>
> <input type="radio" name="Otherlanguage" value="1">
> <input type="radio" name="Otherlanguage" value="2">
> <input type="radio" name="Otherlanguage" value="3">
>
> I have a set of radioboxes, four for each language. Say I have about 100
> languages to display, so I would need about 400+ lines of code written

> My solution is:
>
> ---file1.jsp---
>
> <input type="radio" name="<%= request.getParameter("language")%>"
> value="0" checked>
> <input type="radio" name="<%= request.getParameter("language")%>"
> value="1">
> <input type="radio" name="<%= request.getParameter("language")%>"
> value="2">
> <input type="radio" name="<%= request.getParameter("language")%>"
> value="3">
>
> ---end of file1.jsp---
>
> --file2.jsp---
>
> <jsp:include page="file1.jsp" flush="true">
> <jsp:param name="language" value="English"/>
> </jsp:include>
> <jsp:include page="file1.jsp" flush="true">
> <jsp:param name="language" value="Otherlanguage"/>
> </jsp:include>
>
> ---end of file2.jsp---

> This is more convenient but still time consuming.

> out.print("<input type=\"radio\" name=\"" + language + "\"

> out.print("<input type=\"radio\" name=\"" + language + "\"
