RESTEasy Client + NoSuchMethodError

Question

I am trying to write simple RESTEasy client. Below given is sample code:

Client client = ClientBuilder.newBuilder().build();
WebTarget target = client.target         


        

Answer 1

At last after banging my head for couple of days, I could resolve these issues.

Solution for issue 1:

Error: "java.lang.NoSuchMethodError: org.jboss.resteasy.spi.ResteasyProviderFactory.(Lorg/jboss/resteasy/spi/ResteasyProviderFactory;)"

Solution: I resolved this issue, by adding more resteasy modules in exclusion list inside jboss-deployment-structure.xml. My current state of jboss-deployment-structure.xml is as:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
   <deployment>
      <dependencies>
            <module name="org.jboss.resteasy.resteasy-jackson-provider" services="import"/>
       </dependencies>
       <exclude-subsystems>
           <subsystem name="resteasy"/>
       </exclude-subsystems>
     <exclusions>

        <module name="javax.xml.soap.api"/>
        <module name="javax.xml.ws.api"/>

        <!-- This one always goes last. -->
        <module name="javax.api"/>

       <module name="org.apache.commons.logging"/>
       <module name="org.jboss.as.jaxrs"/>
       <module name="org.jboss.resteasy.resteasy-jaxrs"/>
       <module name="org.jboss.resteasy.resteasy-cdi"/>
       <module name="org.jboss.resteasy.resteasy-jackson2-provider"/>
       <module name="org.jboss.resteasy.jackson-provider"/>
       <module name="org.jboss.resteasy.resteasy-atom-provider"/>
       <module name="org.jboss.resteasy.resteasy-hibernatevalidator-provider"/>

       <module name="org.jboss.resteasy.resteasy-jettison-provider"/>
       <module name="org.jboss.resteasy.resteasy-jsapi"/>

       <module name="org.codehaus.jackson.jackson-xc"/>
       <module name="org.codehaus.jettison"/>
       <module name="javax.ws.rs.api"/>
       <module name="javax.ws.rs.core"/>
     </exclusions>
   </deployment>
 </jboss-deployment-structure>

I believe, it could have worked by simply excluding modules "org.jboss.resteasy.resteasy-jaxrs" and "org.jboss.resteasy.resteasy-cdi". But I did not try further as I faced another issue. You can try by removing un-necessary exclusions.

Solution for issue 2:

Error: "Caused by: java.lang.NoSuchMethodError: javax.ws.rs.core.Response.readEntity(Ljava/lang/Class;)Ljava/lang/Object;"

Solution: JBOSS EAP 6.1, is bundled with default resteasy distribution. I downloaded latest resteasy jax-rs implementation (resteasy-jaxrs-3.0.7.Final-all.zip) from location.

It comes with zip file called resteasy-jboss-modules-3.0.7.Final.zip. Unzip this file inside modules/system/layers/base/ directory of the JBoss EAP 6.1 distribution. This will overwrite some of the existing files there. This will resolve second issue.

Hope this information would help others.

Answer 2

This problems are thrown cause of different version of Resteasy Client implementation between your app and Jboss EAP modules. You are using the newest version of jaxrs-client, but JBoss EAP 6.3.0 use very old version (resteasy-jaxrs-2.3.8.Final-redhat-3).

Just download latest pack of JBoss Resteasy implementation (sometking like this: resteasy-jboss-modules-3.0.9.Final.zip) and unzip into EAP Modules folder replacing existing files modules.xml and adding new jars. Remeber replace all JARS from the ZIP (not only resteasy-jaxrs).
