最后，事实证明，您实际上必须替换比Oracle建议更多的jar。这是我的weblogic-application.xml的样子：
<prefer-application-packages> <package-name>com.sun.jersey.*</package-name> <package-name>org.glassfish.jersey.*</package-name> <package-name>org.glassfish.hk2.*</package-name> <package-name>org.jvnet.hk2.*</package-name> <package-name>jersey.repackaged.org.objectweb.asm.*</package-name> <package-name>com.sun.research.ws.wadl.*</package-name> <package-name>com.sun.ws.rs.ext.*</package-name> <package-name>org.prehaus.jackson.*</package-name> <package-name>com.fasterxml.jackson.*</package-name> <package-name>org.prehaus.jettison.*</package-name> <package-name>javax.ws.rs.*</package-name> <package-name>org.objectweb.asm.*</package-name> <package-name>antlr.*</package-name> </prefer-application-packages>
希望能帮助到你。
