Question

I don’t know what library I should include to be able to use @PartType("application/json") annotation when outputing multipart/mixed data with resteasy.

Answer 1

If you’re using maven, add this dependency to your pom.xml:

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
    <version>2.2.1.GA</version>
</dependency>

If you’re not using maven, add the resteasy-multipart-provider-2.2.1.GA.jar to your classpath.
