What requirements are necessary in order to properly call getString(String key) function in a Wicket WebPage?

Question

I have one Wicket (6.19) bundle including:

HomePage.java
HomePage.html
HomePage.properties.xml

In the .java file I have this code :

public class HomePage extends BasePage {
    public HomePage() {
        add(new Label("message", getString("greetingMessage")));
    }
}

and in the .properties file I have this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM
    "http://www.oracle.com/webfolder/technetwork/jsc/dtd/properties.dtd">
<properties>
    <entry key="greetingMessage">Hello</entry>
</properties>

The problem is that calling the getString method returns an exception :

java.util.MissingResourceException: Unable to find property: 'greetingMessage' for component: [class=com.mycompany.HomePage]. Locale: null, style: null

What am i doing wrong ?

Check your console:

WARN - PropertiesFactory - Unable to find resource file:/.../HomePage.properties.xml
java.util.InvalidPropertiesFormatException: org.xml.sax.SAXException: Invalid system identifier: http://www.oracle.com/webfolder/technetwork/jsc/dtd/properties.dtd

So replace the doctype declaration:

<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">

Better use add(new Label("message", new ResourceModel("greetingMessage")));.

Also make sure the .properties.xml file is copied by your build tool to HomePage.class, so it is available later at runtime.

yes , it is copied and is available at runtime , adding ResourceModel instead of getString did not resolve the problem – Moroianu Alexandru Feb 18 '15 at 14:13

try

new Label("message", new StringResourceModel("greetingMessage", this, null).getString());
