There are no proxy providers registered

mprk Mar 26, 2014 10:29 AM

I'm having trouble connecting to any JAX-RS service or having the @AfterInitialization

annotated method to fire. It seems like the MessageBus never actually activates.

Do the share Service endpoints have to be in the top-level "shared" directory,

or can they exist in subpackages within the "shared" directory? Or do I have

to explictly defined them in some configuration file?

I'm running Errai 2.4.3.Final. It's compiled and run with maven. Running on JBoss AS 7.

I've looked at the suggestions listed for 14.3 in this guide:

http://docs.jboss.org/errai/2.2.0.Final/errai/reference/html/sid-32473113.html

1. ErraiApp.properties is in /src/main/resources.

2. I'm not sure what the proxy code looks like for .errai/RpcProxyLoaderImpl.java. I've included the generated version below.

3. My service endpoints exist in a subpacked of the shared directory.

My goal is to populate a map on start-up, which calls into a web service to get the data from a lucene index.

=========================================

I have a class to hold the Map.

=========================================

@Page

@ApplicationScoped

public class MapView extends DockPanel {

@Inject

Caller<SearchEndpoint> searchService;

//I check that this does get initialized prior to calling searchService

RequestDispatcher dispatcher = ErraiBus.getDispatcher();

public MapView() {

super();

defaultMapOptions = new MapOptions();

defaultMapOptions.setNumZoomLevels(16);

defaultMapOptions.setProjection("EPSG:4326");

defaultMapOptions.setMaxExtent(new Bounds(-180, -90, 180, 90));

defaultMapOptions.setUnits(MapUnits.DEGREES);

initMapWidget(defaultMapOptions);

}

// @AfterInitialization -- tried this, never was activated.

public void initializeMap(){

GWT.log("!!!!!!!!!!!!!!!!!!! AfterInitializing map....");

GWT.log("Dispatcher null? : " + (dispatcher == null) );

//code omitted.

//Recursively start populating map.

try {

populateMap(1);

} catch (Exception e ){

GWT.log( e.toString() );

e.printStackTrace();

}

/**

* Recursively populate map

* @param start

@SuppressWarnings("rawtypes")

public void populateMap(final int start){

// code removed....

// First way I tried to call it.

//RestClient.create(SearchEndpoint.class, new RemoteCallback<List>() {

// Revised way of calling it. This is where the stack trace occurs.

searchService.call( new RemoteCallback<List>() {

@Override

public void callback(List response) {

// good response.

}

}, new RestErrorCallback() {

@Override

public boolean error(Request message, Throwable throwable) {

// bad response

}

}).searchMap(criteria);

}

==========================

Here is the final stack trace:

I have a JAX-RS interface defined in

package com.test.client.shared.services;

Here is the generated code for the RPCProxyLoaderImpl. I can't tell whether this is correct,

or whether it should have specific references to the JAX-RS service endpoints. It was difficult to

discern what is actually required according to the 14.3 reference material.
