RuntimeException: There are no proxy providers registered

mjm.ent Dec 12, 2016 3:35 AM

I can't get any RPC / Rest calls to work, this error occurs during the call to :

@PageShown

void onPageShown() {

MessageBuilder.createCall((final Result result) -> {

Window.alert("Result received : " + result.toString());

}, ResultService.class).getResult(number);

}

Remote service interface :

@Remote

public interface ResultService {

Result getResult(final int number);

}

Remote service implementation :

@Service

public class ResultServiceImpl implements ResultService {

@Override

public Result getResult(final int number) {

final Result result= new Result();

result.setNumber();

return result;

}

And the DTO

@Portable

public class Result implements Serializable {

private Integer number;

public Integer getNumber() {

return number;

}

public void setNumber(Integer number) {

this.number = number;

}

Note that I do not have errai-weld-integration.jar on the classpath, so I have included in web.xml :

I think weld-integration is not compatible with v4.0.0.6Beta, I am using errai-cdi-server which seems to make no difference, I still need to declare the servlet in web.xml

<servlet-name>ErraiServlet</servlet-name>

<servlet-class>org.jboss.errai.bus.server.servlet.DefaultBlockingServlet</servlet-class>

<init-param>

<param-name>auto-discover-services</param-name>

<param-value>true</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>ErraiServlet</servlet-name>

<url-pattern>*.erraiBus</url-pattern>

</servlet-mapping>

I am not using the RPC in a @Postconstruct method and I have verified that RpcProxyLoaderImpl.java contains the code to make the RPC call.
I have also registered listeners to InitVotes to ensure that setup initializes properly.
The console log confirms that the server handshake

21:54:13 INFO [ClientMessageBus] sending handshake message to remote bus ErraiConsoleLogHandler.java:83

21:54:14 INFO [ClientMessageBusImpl$ProtocolCommandProcessor] my queue session id: 76bdafb05de7da7fa1b813b094cf9a603a7687d383be8adce610f546c5ae2f

The method onPageShown() fails systematically with :

@ Impl.java:77

ErraiConsoleLogHandler.java:87 java.lang.RuntimeException: There are no proxy providers registered.

Hi Mathieu,

In my experience there are two things that can cause this issue. The first possibility is that a remote proxy has not been generated for @Remote interface. You can check for this by running super devmode and opening the app in chrome: use the chrome dev tools source tab and search for the RpcProxyLoaderImpl. If the RpcProxyLoaderImpl does not contain an inner class that extends your @Remote interface or you cannot find the RpcProxyLoaderImpl type, then there was a problem generating the @Remote interface. Usually this issue is fixed by clearing your GWT code server cache in SDM (launch SDM, go to the codeserver URL in a browser, navigate to your app, click the "clear cache" button).

The other possibility is that your @PageShown method is invoked before the proxies are registered. This shouldn't happen, but I have recently observed this behaviour in a demo. You can test for this by changing your @PageShown to an @AfterInitialization.

Cheers.

Hi Max,

It seems that I had some serious build issues, they're resolved now.

I think the reason for my troubles is that the output directory is outside the ${basedir}. The org.jboss.errai.cdi.* and org.jboss.errai.marshalling.* classes were not created (or only created in the temp directory and never copied to /WEB-INF/classes. The compiler output is below :

Is there any way to configure the output directory ?

Hi Mathieu,

You can use this system property to explicitly declare the directory where Errai should emit generated class files: errai.server.classOutput

Cheers.

Hi,

I cannot get this to work, classes are always compiled to ${basedir}/target/classes

I have also tried using errai.marshalling.server.classOutput instead...

I have tried setting maven properties :

    <properties>
        <errai.server.classOutput>${basedir}/target/classes/war/WEB-INF/classes</errai.server.classOutput>
    </properties>

Or GWT compiler properties :

   <systemProperties>
       <property>
           <name>errai.server.classOutput</name>
           <value>${basedir}/target/classes/war/WEB-INF/classes</value>
       </property>
   </systemProperties>

Or Maven properties-plugin :

            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>properties-maven-plugin</artifactId>
                <version>1.0.0</version>
                <executions>

                        <goals>
                            <goal>set-system-properties</goal>
                        </goals>
                        <configuration>
                            <properties>
                                <property>
                                    <name>errai.server.classOutput</name>
                                    <value>${basedir}/target/classes/war/WEB-INF/classes</value>
                                </property>
                            </properties>
                        </configuration>

mbarkley Dec 28, 2016 10:34 AM (in response to mjm.ent)

Hi Mathieu,

I just verified that setting the property in the errai-tutorial works. I added "-Derrai.server.classOutput=$PATH" to the "extraJvmArgs" tag for the gwt-maven-plugin configuration. Maybe setting the property this way will work for you?

Cheers.
