問題： App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file. Apple在iOS9之後新增App Transport Security(ATS)的機制，禁止訪問未加密的連線，如果沒有特別排除這個設定，會遇到這個錯誤。 解決方法： 1. 設定排除domain <key>NSAppTransportSecurity</key>     <dict>         <key>NSExceptionDomains</key>         <dict>             <key>www.domain.com</key>             <dict>                 <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>                 <true/>             </dict>         </dict>     </dict> 2. 關閉ATS機制，此方法允許訪問ip位址  <key>NSAppTransportSecurity</key>     <dict>         <key>NSAllowsArbitraryLoads</key>         <true/>     </dict> reference: https://forums.developer.apple.com/thread/6205 https://developer.apple.com/library/prerelease/ios/technotes/App-Transport-Securit

當用jersey 1.19建立RESTful服務時，遇到java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer的錯誤訊息。 解決方法： 1.將相關jar檔全複製到web-inf/lib/之內，就可以解決。(asm-3.3.1.jar, jersey-bundle-1.19.jar, jersey-core-1.19.jar, jersey-server-1.19.jar, son-20140107.jar, jsr311-api-1.1.1) 2. the server had no jars in the lib folder. Make sure it has access to all dependencies in: project -> properties -> development assembly -> add -> java build path entries. 正常啟動tomcat產生的訊息如下： 十月 20, 2015 4:35:02 下午 org.apache.catalina.core.StandardService startInternal INFO: Starting service Catalina 十月 20, 2015 4:35:02 下午 org.apache.catalina.core.StandardEngine startInternal INFO: Starting Servlet Engine: Apache Tomcat/7.0.52 十月 20, 2015 4:35:05 下午 com.sun.jersey.api.core.servlet.WebAppResourceConfig init INFO: Scanning for root resource and provider classes in the Web app resource paths:   /WEB-INF/lib   /WEB-INF/classes 十月 20, 2015 4:35:05 下午 com.sun.jersey.api.core.ScanningRe
