NoSuchMethodError javax.ws.rs.core.Application.get

Question

I am trying my first REST application.

Below is my configuration:

• Java 7
• JBoss AS 7.1
• Jersey 2.22.2

Below are list of jars downloaded by Maven:

On server starting, I am getting the below exception:

According to the logs above ApplicationHandler.init() method is calling Application.getProperties().

ApplicationHandler is in jersey-server-2.22.2.jar and Application is in javax.ws.rs-api-2.0.1, both jars are present in build path.

But still I am getting NoSuchMethodError. I have checked below links:

• link 1 I am not using swagger at all;
• link 2 I couldn't see more than one version of Application class;
• link 3 I am using JRE 7 and JBoss AS 7.1 is also JDK 7 compatible.

So I have only one Application which contains getProperties() method and even then I am getting NoSuchMethodError. Can any one please give me reason why this is happening?

Answer 1

As mentioned in the JBoss AS 7 documentation, the version of the JAX-RS specification used is 1.1.

Therefore, in order to use Jsersey 2.X, which provides support for JAX-RS APIs and serves both JAX-RS 1.x and JAX-RS 2.x reference implementations, you need to exclude the conflicts with RESTEasy by adding the following to your WEB-INF/jboss-deployment-structure.xml:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <!-- Exclude RestEasy conflicts -->
            <module name="javaee.api" />
            <module name="javax.ws.rs.api"/>
            <module name="org.jboss.resteasy.resteasy-jaxrs" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

Also, you need to add the following to your web.xml:

<context-param>
    <param-name>resteasy.scan</param-name>
    <param-value>false</param-value>
</context-param>
<context-param>
    <param-name>resteasy.scan.providers</param-name>
    <param-value>false</param-value>
</context-param>
<context-param>
    <param-name>resteasy.scan.resources</param-name>
    <param-value>false</param-value>
</context-param>
