Reload ResourceBundle
Hi,
I am working on a web app using Struts 1.2.4 (+ Spring 1.2.6 + Tomcat 5.5.9).
The app has two versions - English and Traditional Chinese. I use
ResourceBundle + tag to achieve this.
Properties file
==
WEB-INF/classes/message.properties
WEB-INF/classes/message_zh_TW.properties
==
Now I want to update the properties files without reloading the app. I googled
and found
Class klass = ResourceBundle.getBundle("message",
locale).getClass().getSuperclass();
Field field = null;
try {
field = klass.getDeclaredField("cacheList");
} catch (NoSuchFieldException noSuchFieldEx) {
System.err.println(this.getClass().getName()+" : "
+noSuchFieldEx.getMessage());
}
field.setAccessible(true);
SoftCache cache = null;
try {
cache = (SoftCache)field.get(null);
} catch (IllegalAccessException illegalAccessEx) {
System.err.println(this.getClass().getName()+" : "
+illegalAccessEx.getMessage());
}
cache.clear();
field.setAccessible(false);
The above code snippet can be found in numerous places but unfortunately it
doesn't work for me (no effect after executing).
Anyone help?
Thanks in advance.
Michael

RE： RE: Session without cookies
Hi Chandra,
As far as I know, the attribute "cookies" of the
"Context" node in Tomcat server.xml is the only place
I need to set. From the doc,
http://tomcat.apache.org/tomcat-5.5-doc/config/context.html
cookies:
Set to true if you want cookies to be used for session
identifier communication if supported by the client
(this is the default). Set to false if you want to
disable the use of cookies for session identifier
communication, and rely only on URL rewriting by the
application.
Thanks.

Hi Chandra,
Thanks for your prompt reply.
I have checked many many times and I have 100% sure
there is no
Request.getSession(true);
in all my action classes.
Thanks.

Session without cookies
Hi All,
I have been searching for hours and still cannot find
any useful info. Hope you can help.
I am building a Struts app. (Struts 1.2.4 + Tomcat 5.5
+ Apache 2.0.55 + Spring 1.2.6) and want to use
session without
enabling cookies. I use to create links so
;jsessionid is appended to the end. Fine. The problem
I have is every time I access a page, a new session id
is created so essentially everything stored in session
is lost. Here is some output from my test action,
test.do:
test.do
=
HttpSession session = request.getSession();
System.out.println("Is session new? " +
session.isNew());
System.out.println("Session id: " + session.getId());
First access
=
Is session new? true
Session id: B9F9E135DCBAC90AB2B5AEBCE901FAA5
Second access
=
Is sesssion new? false
Session id: 8CCE7A388E76C0F56016E8F41E29E0E5
The session is not new but the id is different...I
already set in Tomcat server.xml
What am I missing??
Thanks in advance.
Michael
