在eclipse中部署REST Web服务的问题

标签： eclipse rest tomcat jax-rs

我正在eclipse中使用JAX-RS编写REST Web服务，并将tomcat作为服务器。 我指的是以下教程来编写Web服务： http://www.vogella.com/tutorials/REST/article.html

当我运行项目时，我收到以下错误：

3 个答案:

答案 0 :(得分：10)

错误消息显示：

Unsupported major.minor version 51.0
(unable to load class org.glassfish.jersey.servlet.init....)

这意味着您正在使用java 6 VM，并尝试加载包含为java 7构建的类的jar。 您应该尝试升级到java7，或者找到/重建与java6兼容的泽西版本。

您可以在http://en.wikipedia.org/wiki/Java_class_file看到java类的不同major.minor值，以及相应的jdk版本：

J2SE 8 = 52,
J2SE 7 = 51,
J2SE 6.0 = 50,
J2SE 5.0 = 49,
JDK 1.4 = 48,
JDK 1.3 = 47,
JDK 1.2 = 46,
JDK 1.1 = 45

答案 1 :(得分：0)

使用更高 Java版本进行编译，而不是用于运行应用程序的版本。

正如@tonio所建议的那样，要么升级运行时JRE，要么使用以下代码编译为较低的Java版本：

javac -source 6 *.java

答案 2 :(得分：0)

dynamic web module版web.xml版2.5使用{{1}}它应该有效。
