problem when reading properties file
I want to read a properties file test.properties, and show the value which is
defined in properties file in a lable. But I can't read the properties file
I have tried
property.load(ClassLoader.getSystemResourceAsStream(test.properties));
property.load(this.getClass().getClassLoader().getResourceAsStream(test.properties));
property.load(PackageResource.get(test.class,
test.properties).getResourceStream().getInputStream());
property.load(((WebApplication)
Application.get()).getServletContext().getResourceAsStream(test.properties));
But it always generate null point error
java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Properties.java:365)
at java.util.Properties.load(Properties.java:293)
Then I tried to test reading in main method, and it works fine there.
public static void main(String[] args){
Properties property = new Properties();
try {
property.load(ClassLoader.getSystemResourceAsStream(test.properties));
} catch (IOException e) {
e.printStackTrace(); }
System.out.println(property.getProperty(a key));
}
Really can't understand why. Did I do something in wrong way? Thanks for any
help or sugestion.

Re: problem when reading properties file
Thanks. But still the lable will show different messages according to different error situation. So even to make it show up conditionally can't solve the problem.

Re: problem when reading properties file
I'm not sure what's wrong, but why not use the i18n feature?
Create a .properties file with name of the page that your label is located,
put it in the same folder of the page (like were you put the html).
The label should be something like this:
add( new Label( page.label, new ResourceModel( page.label ) );
check:
http://cwiki.apache.org/WICKET/general-i18n-in-wicket.html
Hope that was helpful.

Re: problem when reading properties file
so the problem is that you can get different messages? if so, why not use isVisible() as Gabor suggested. And for the String itself, why not use a utility that converts the message to your liking?

Re: problem when reading properties file
Thanks Eyal. I have tried with resourceModel before, it works fine. But my label only show the message when the web service returns error, not constant showing.

Re: problem when reading properties file
Have we discussed *why* you're doing what you're doing? Perhaps you're approaching the problem the wrong way. Care to share the actual problem you're facing which caused you to choose this approach with us?

Re: problem when reading properties file
:) The problem is that I have to get different massages from properties file, and then comes to my original question. hmm i tried Chinese, Thais and some others. But i never got a massage from a property file, how does that feel?? johan
Re: problem when reading properties file
Sure.
Maybe I need to explain more explicitly.
I will get the unique error code from web service if there is something
wrong. And then I would like to map the error codes to user-friendly
messages (which are in properties file), and show the messages conditionally
based on the error type in a label.
For example
if(error code == 1){
add(new Label(a, property.getProperty(key1)));
} else if (error code ==2){
.
}
So the first thing is that I have to read the properties file and let the
property to load it, so I can get the value(the message which I want to
show).
And problen is whatever I tried, it failed to read as what I wrote before

Have you looked at org.apache.wicket.model.ResourceModel? You could do:
new Label(a, new ResourceModel(key1))

Re: problem when reading properties file
Exactly as James suggest and what I said earlier:
use something like this,
add( new Label( page.label, new ResourceModel( page.label ) );
Instead of 'page.label' do something like error.label.key#
where key# is what you get from the service.

yup, it works. But I would like to know the way to read the file, for studying and also maybe future use. jwcarman wrote: Have you looked at org.apache.wicket.model.ResourceModel?
