AsynchronousDispatcher error

i am getting the error when i try to upload a file based exactly off the example shown here Sample

The error is

Allocate exception for servlet com.testapp.rest.JaxRsActivator: java.lang.RuntimeException: Unable to find a public constructor for class org.jboss.resteasy.core.AsynchronousDispatcher

What can this mean?

Solution

  • If deploying to JBoss 7.x you need to change the scope of your resteasy dependencies to provided. This is because those particular libraries are already included in JBoss as modules:

    <dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>2.2.1.GA</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
    <version>2.2.0.GA</version>
    <scope>provided</scope>
</dependency>
