我正在关注教程:
http://www.vogella.com/tutorials/REST/article.html - 这是Eclipse中的初学者Jersey / REST教程。
我的tomcat服务器自行启动正常,但是当我尝试在教程的6.5节中运行Hello.java时,我得到了一些错误并且tomcat无法启动[有几个错误 - 全部类似]

我的WEB-INF\lib\
文件夹包含:
javax.ws.s-api-2.0-sources.jar
javax.ws.rs-api-2.0.1.jar
jersey-client.jar
jersey-common.jar
jersey-container-servlet-core.jar
jersey-media-jaxb.jar
jersey-server.jar
JRE
是1.8.0_101
JAX-RS
为2.23.2
Tomcat
8.0.36
我想知道这是否是我的问题:
Whenever I try to run Tomcat with Jersey, it refuses to load
但不确定如何检查我需要匹配的版本?
答案 0 :(得分:1)
确定。答案是 ALL 为Jersey下载的jar必须被复制到\ WEB-INF \ lib(即从泽西档案库中的\ lib \ ext和\ api中的jar)。
也感谢这个帖子。
