I'm trying to make a REST webservice using RESTEasy and Weld for injection. When the package is deployed on wildfly I have no problem, but when trying test the service I get the error below.
I have no idea how to solve this.
Does anyone can help me?

You should not add weld and resteasy dependencies if you do not use specific weld or resteasy features. And if you do so, you should put those dependencies with the provided scope. Else it will be packaged in your WAR.
But looking at your code, you do not seem to use specific weld or resteasy features. What i recommend in this case, is just adding a single dependency for Java EE apis, and nothing else:
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
Wildfly will provide all implementations at runtime.
