Hi,

I followed the basic tutorial to translate my application.

1) I created a Message class
package biz.company.i18n;

public class Messages {
public String label;
public String msg;
}

2) In my package biz.company.i18n I have my property file: Messages.properties
label= testTitle
msg= Mon message

3) In my custom classes I have for example:

public class Test {

@Inject
@Translation
Messages messages;

private void test(){

MessageBox messageBoxTest = new MessageBox(shell, SWT.ICON_QUESTION
| SWT.YES | SWT.NO);
messageBoxTest.setMessage(messages.label);
messageBoxTest.setText(messages.msg);
int responseTest = messageBoxTest.open();

...

Result:
org.eclipse.e4.core.di.InjectionException: java.lang.NullPointerException
