Deferred binding failed

Question

My application is throwing:

java.lang.RuntimeException: Deferred binding failed for 'com.mygwtapp.client.gin.ClientAppGinjector' (did you forget to inherit a required module?)

on this code inside the EntryPoint:

private final ClientAppGinjector injector = GWT.create(ClientAppGinjector.class);

What could be the problem?

Here's the full error Log:

Answer 1

In your ".gwt.xml" file, add the following line:

<inherits name="com.google.gwt.inject.Inject"/>

Answer 2

I had the same problem. My getter method of Boolean object called getBooleanObject() instead of isBooleanObject(). Class JsonEncoderDecoder looked for method called isBooleanObject(), didn't find him, compilation failed. (gwt 2.8.0)

Answer 3

I had the same problem, I resolved lom adding the following libraries:

• javax.inject.jar
• guice-assistedinject-3.0.jar
• aopalliance.jar

Answer 4

I've had the same error message during runtime. When I tried "Google > GWT Compile" the stack trace helped me better. My problem was that the service interface used a class that wasn't serializable.
