Hi all,
I've build a little util class for sucking in properties. When I use it
from "command line" progs it seems to work okay, but when I call it from
a servlet it never seems to load an *updated* version of the
.properties file.
I am using a HashMap to cache the Properties and associated timestamp
(of type long). It detects a stale timestamp okay - then goes through
the Properties.load( ... ) but the returned Properties seem to always be
the ones it first loaded.
If I restaart Tomcat the newest version of the Properties file *is*
loaded.
Here's some of the util code...
<snip>
static private Properties loadPropertiesFile(Class callerClass,
String configName) {
Properties appProperties = null;
...
if detect "stale" timestamp on disk property file
vs. the cache one, set "entry = null" - this works...
...
if (entry == null) {
// create and load properties
appProperties = new Properties();
appProperties.load(callerClass.getResourceAsStream(
configName + ".properties"));
// stuff it in the cache
entry = new MapEntry(lastModified, appProperties);
propertiesCache.put(appName, entry);
appProperties.list(System.out);
}
...
...
<snip>
And here's how I test it from a servlet...
<snip>
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws
ServletException, IOException {
PrintWriter out = res.getWriter();
try {
Properties prop = null;
prop =
HAL_PropertiesUtils.getPropertiesHandler(this.getClass(),
"PropertiesUtilsServlet");
out.println(prop.getProperty("name"));
}
catch (Exception ex) {
}
}
<snip>
Any wisdom on this? Do I have to do something different/extra when
loading properties in this way under Tomcat?
I just do all this so the .properties files can be found in the same dir
as whatever class calls the util.
