无法找到媒体类型的JAXBContextFinder:application/json

Question

我有开发resteay + ejb + json的问题.使用Jboss-5.1.0.GA.我从resteasy-jaxrs得到了例子并且适合我的情况.在jboss-5.1.0.GA\server\default\lib \中添加了jar(这个问我jboss.在其他情况下捕获异常 - 类未找到)

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

得到例外

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

你需要从http://jettison.codehaus.org/获得一个JAX-B JSON库
