Tomcat的JAX-RS異常

Question

當啓動一個servlet（來自eclipse）時，出現以下錯誤： 它是tomcat 7和servlet是REST。

有沒有人有一個提示？ 謝謝！

Answer 1

首先檢查這個類是否真的存在。檢查課程名稱和包裹。它屬於Web項目還是屬於相關項目？

如果一切正常，請刷新項目，然後運行Project/Clean，然後清理並重新發布tomcat。如果它不起作用再次創建服務器（我的意思是在eclipse中）。如果仍然無效，請轉至C:\beezer\WebServerWorkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\BeezerServer\WEB-INF\classes（該路徑取自您的日誌）並檢查該類文件是否存在。

祝你好運，歡迎的是對花費在Tomcat中的Eclipse插件的蟲子夜戰人俱樂部

Answer 2

擺脫C:\beezer\WebServerWorkspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\BeezerServer\WEB-INF\lib\geronimo-j2ee_1.4_spec-1.1.jar它包含類Servlet.java，應該由提供AS本身。如果您正在使用Maven，請標記所提供的依賴關係（<scope>provided</scope>）

Btw。該jar仍然需要編譯，但不是在運行時。

編輯：哦，現在我已經注意到，它只是在日誌中的信息。所以這不是問題的根源，根本原因是ClassNotFound前。確保該類在類路徑上。
