Problem reading property file in GWT

[Vibhuti Agarwal]

Hello 

I am facing problem reading property file in GWT. I created an interface which extends the Constants interface and defined methods corresponding to the properties in properties file. 

When I run my application I get the following errors:

com.google.gwt.i18n.rebind.AbstractResource$MissingResourceException: No resource found for key 'display.alert'

    at com.google.gwt.i18n.rebind.AbstractResource$ResourceList.getRequiredStringExt(AbstractResource.java:246)

    at com.google.gwt.i18n.rebind.SimpleValueMethodCreator.createMethodFor(SimpleValueMethodCreator.java:95)

    at com.google.gwt.i18n.rebind.AbstractLocalizableImplCreator.delegateToCreator(AbstractLocalizableImplCreator.java:313)

    at com.google.gwt.i18n.rebind.ConstantsImplCreator.emitMethodBody(ConstantsImplCreator.java:163)

    at com.google.gwt.user.rebind.AbstractGeneratorClassCreator.genMethod(AbstractGeneratorClassCreator.java:265)

    at com.google.gwt.user.rebind.AbstractGeneratorClassCreator.emitMethods(AbstractGeneratorClassCreator.java:233)

    at com.google.gwt.user.rebind.AbstractGeneratorClassCreator.emitClass(AbstractGeneratorClassCreator.java:116)

    at com.google.gwt.i18n.rebind.AbstractLocalizableImplCreator.generateConstantOrMessageClass(AbstractLocalizableImplCreator.java:133)

As per the java docs, I have created the properties file in the same name as the interface i.e. Test.java(I) and Test.properties. 

I am accessing the constants the following way:

public interface Test extends com.google.gwt.i18n.client.Constants{

@Key("display.alert")

    String displayAlert();

}

public static Test constants = (Test) GWT.create(Test.class);

constants.displayAlert();

Any ideas on what am I missing here.

Thanks

You may have better luck in GWT discussion groups...
Anyway it seems you're mixing Constants and Message annotations.

The correct way is

class Test extends Constants{
@DefaultStringValue("this is my alert!!")
public String displayAlert();
}

//use
public static Test constants = GWT.create(Test.class); //No cast
needed
Window.alert(constants.displayAlert());

Test_**.properties
displayAlert = message for language **

Thanks Lorenzo. The link was very useful. 

Actually the issue was resolved when I placed the properties file in the same package where my interface was placed.
