How to update translations in client-app

[rula]

Hello,

how can I reach a simple update of the the messages-catalog in the client-app?
Only if I stop and start the server, the message-resources are updated.
I think a simple reload is enough, but I can't find a way to reach this.

In admin-app there is no problem, I do the changes and klick only F5 in the browser and the all seems to be okay.

Hi,

The application uses the Struts message resource file which is loaded into memory when the Action servlet is initialized. Rather than starting and stopping the server, just reloading the application should work. If you do a search on the web you will find that many people have worked around this problem by making some struts customizations (e.g. http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=58&t=007061 ).

Hi,

i found many different solutions in the java-ranch-threat.

The last entry by Michael Böckling is my private favourite.

two utility-classes:
- ReloadablePropertyMessageResources.java
- ReloadablePropertyMessageResourcesFactory.java
and one change in struts-config.xml:
<message-resources parameter/>

Have anybody here proved this way?

Hi,

i need the reload of message-resources prior for configuration and performance is not so important.
So, i think i should solve this problem in tomcat with the reloadable-attribute of the context-element.

like here in the tomcat-doc:

Set to true if you want Catalina to monitor classes in /WEB-INF/classes/ and /WEB-INF/lib for changes, and automatically reload the web application if a change is detected. This feature is very useful during application development, but it requires significant runtime overhead and is not recommended for use on deployed production applications. That's why the default setting for this attribute is false. You can use the Manager web application, however, to trigger reloads of deployed applications on demand.

First i test to use the tomcat-manager-app!

Hi,

in server.xml i use this:
        <Context path="/konakart"
                 reloadable="false"
                 docBase="C:\Programme\konakart2.2.4\webapps\konakart"/>

by the reload occurs the exception below:

'Has no functional impact', but where is the problem.

It works for me, the message-resources are refreshed.

Could not load java.net.BindException
