Crash @Inject using RESTEasy, Weld and Wildfly

I am trying to create a REST web service using RESTEasy and Weld Injection. When the package is deployed to wildfly I have no problem, but when trying to test the service I get the below error.

I don't know how to solve this.

Can anyone help me?

You cannot add weld and relaxation constraints unless you use the special weld or restyling functions. And if you do, you have to put those dependencies in the scope provided

. Otherwise it will be packaged in your WAR.

But looking at your code, you don't seem to be using the special welding or restyling functions. What I recommend in this case simply adds one dependency for the 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.

Java EE 7 has implicit archives bean by default. Your class HelloWorld

has no scope annotation, so it is not treated as a bean driven by CDI, and injection into that class does not work.



Try adding @ApplicationScoped

.

I put the bags as said, as Benjamin said, then I remove the old wild petal and unpack the other. In the new wilderness, the solution works.

The problem is you are using single lists to represent your endpoints. Since you create them, you bypass the injection. You can remove all methods from your class RESTConfig

or return it to the class getClasses()

. There is no need to specify them in the EE application as the container is for scanning.
