找不到适用于媒体类型的JAXBContextFinder：application / json [英] Could not find JAXBContextFinder for media type: application/json

问题描述

我有开发resteay + ejb + json的问题。使用Jboss-5.1.0.GA。我从resteasy-jaxrs得到例子，适应我的情况。
添加jars（这让我jboss，在其他情况下抓到异常 - 找不到类）到\jboss-5.1.0.GA\server\default\lib\

I have a problem with development resteay+ejb+json. Using Jboss-5.1.0.GA. I get example from resteasy-jaxrs and adapted to use for my case. Added jars(this ask me jboss. in other case catch exception - class not found) into \jboss-5.1.0.GA\server\default\lib\

resteasy-jaxb-provider-1.2.1.GA
jaxrs-api-2.0.1.GA
resteasy-jaxrs-2.0.1.GA

resteasy-jaxb-provider-1.2.1.GA jaxrs-api-2.0.1.GA resteasy-jaxrs-2.0.1.GA

推荐答案

RestEasy不再包含JAR中的JSON支持。
http：/ /docs.jboss.org/resteasy/docs/2.0.0.GA/userguide/html_single/index.html#JAXB_+_JSON_provider

RestEasy no longer includes JSON support in the JARs. http://docs.jboss.org/resteasy/docs/2.0.0.GA/userguide/html_single/index.html#JAXB_+_JSON_provider

您需要从 http://jettison.codehaus.org/ 获取一个JAX-B JSON库

You need to go get a JAX-B JSON library from http://jettison.codehaus.org/
