String as Parameterwith html:link
Hi,
I have a question concerning the Struts-HTML-Tag <html:link>. I want to
generate a link to an action with one parameter which is a hardcoded
String (not a value of a bean property which is present in a scope). And
I don't want to use the url-Attribut but the action-Attribut to generate
the link to the action. One example link could be:
http://mydomain/setLocale.do?lang="de".
What I'm doing now is: create a HashMap with one entry and use the
name-Attribut:
<jsp:useBean id="langParamMap" class="java.util.HashMap"/>
<c:set target="${langParamMap}" property="lang" value="de"/>
<html-el:link action="setLocale" name="langParamMap">
lang
</html:el>
That works fine, but just out of curiosity: Is there really no
possibility to just provide a string via an attribute of html:link which
then is appended literally to the generated URL as a parameter. And if
not is there a special reason for it?
Regards
Franz

You can use paramId, paramName and paramPropery to supply a single parameter w/out building a map, though that still requires the parameter value to be stored in a bean in some scope. There's no way to supply arbitrary values directly (i.e. not from a bean or map) unfortunately.

RE: caching staticJavascript.jsp?
Posted by Aymeric Alibert <ay...@neuf.fr>.
Found the answer to my own question. Just need to give the browser some
hints that it should cache the page. Something like:
- staticJavascript.jsp:
<%@ page language="java" contentType="application/x-javascript" %>
<%@ taglib uri = "http://struts.apache.org/tags-html-el" prefix =
"html"%>
<% response.setHeader("Cache-Control", "max-age=3600");%>
<html:javascript scriptLanguage="true" dynamicJavascript="false"
staticJavascript="true"/>

Subject: caching staticJavascript.jsp?
I am building a Struts (1.2.7) application that client will access using
a slow connection (56K modem) and I am trying to limit the amount of
data downloaded from the server.
Since I am using the Validator, I would like to create an external
staticJavascript.jsp page that could be cached by the browser to hold
the javascript generated by the Validator.
Here is what I have:
- staticJavascript.jsp:
<%@ page language="java" contentType="application/x-javascript" %>
<%@ taglib uri = "http://struts.apache.org/tags-html-el" prefix =
"html"%>
<html:javascript scriptLanguage="true" dynamicJavascript="false"
staticJavascript="true"/>
- agencies.jsp
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<%@ page contentType = "text/html;charset=UTF-8" language = "java"%>
<%@ taglib uri = "http://struts.apache.org/tags-html-el" prefix =
"html"%>
<%@ taglib uri = "http://java.sun.com/jstl/core_rt" prefix = "c"%>
<%@ taglib uri = "http://java.sun.com/jstl/fmt_rt" prefix = "fmt"%>
<html:html locale="true">
<head>
<link rel="stylesheet" type="text/css" href="css/eacadmin.css">
<script type="text/javascript" src="<html:rewrite
href='staticJavascript.jsp'/>" ></script>
</head>
<body>
...
The application is working fine, but the staticJavascript.jsp is
downloaded for each page (I tried both IE and FireFox). Any idea why the
browsers are not caching that page?
Using a sniffer, here is the Request/Response I got each time:
Request:
GET /eacadmin/staticJavascript.jsp HTTP/1.1

Any idea?
Thanks,
Aymeric.
