Web page refresh problem
Hi,
I am newbie to tapestry. Lately I download the tapestry and try to develop a test project to learn how it works. Now I encounter a problem. I think it is basic; but after searching around the FAQ and mail archive (http://mail-archives.apache.org/mod_mbox/tapestry-users/), I do not see any similar problem as mine. So I post it here. Hope some can give me a help.
I follow the Quick Start (http://tapestry.apache.org/tapestry4.1/quickstart/helloworld.html) page to develop my test project.
The problem is, after refreshing the web page, I can not see any change made to the Home.html, in which I add a few line of Javascript. Even a simple html tag (like button), it won't appear on the web page (e.g., http://localhost:8080/hello/app). However, there is no problem if I create another example.war directly without using tapestry. For example, in example.war, I create a page named index.html. Then, I add a button, which would appeared after pressing refresh button.
Is it because tapestry maintain a cache state, which might increase the speed of loading web pages?
Environment I use is Jboss 4.0.5 GA, Debian Sarge testing, JDK1.5.x, Firefox (2.0.0.1)
Thanks your help.
I appreciate it.
Following is the content of Hello.html:
<html>
<head>
<title>Tutorial: Hello World</title>
</head>
<!-- newly added lines BEG -->
<script language="javascript" type="text/javascript">
var request = false;
try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
/* for M$ IE */
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = false;
}
}
}
if (!request){
alert("Error initializing XMLHttpRequest!");
}else{
alert("request object obtained!");//test
}
</script>
<!-- newly added lines END -->
<body>
<h1>Hello World Tutorial!</h1>
<p>
The current data and time is:
<b>
<span jwcid="@Insert" value="ognl:new java.util.Date()">June 26 2005</span>
<!-- newly added lines BEG -->
<input type="button" onClick="alert("xxx!");">
</b>
<p>
<a href="#" jwcid="@PageLink" page="Home">refresh</a>
</p>
<!-- newly added lines END -->
</p>
</body>
</html>

Beware, however..... never use disable-caching=true in production.
Your server will blow up very quickly. I've found even during
development, reloading a complex page several times will cause memory
problems and incredibly slow speed. I'm not sure if this is still true
for 4.1.1. Luckily tapestry 5 will free us from such issues.

Yep.
Try adding "-Dorg.apache.tapestry.disable-caching=true" to whatever
starts up your web server.
