「警告：無法找到所需的類」在製作Web服務客戶端時

Question

我必須從wsdl文件創建Web服務客戶端。我遵循教程來創建和測試eclipse嚮導中的服務客戶端，（我認爲我已經實現了調用該服務的代碼），但我一直得到這個堆棧跟蹤，我知道它可能微不足道，但我沒有設法在互聯網上找到任何東西。我已將這些庫附加到路徑中，因此我無法理解這是什麼，我非常感謝任何幫助，第一次處理Web服務。我不知道，如果它是確定後在這裏整個堆棧跟蹤，其相當大的，但這裏是它的一部分.....

Answer 1

確保activation.jar從JAF (Java Activation Framework)是在類路徑中。

Answer 2

我用eclipse birt reporting viewer在tomcat 8上解決了這個警告/錯誤。

從獲取最新的：

• http://central.maven.org/maven2/javax/activation/activation/
• http://central.maven.org/maven2/com/sun/mail/javax.mail/

並將它們放到安裝目錄（就像在類路徑）：

• /apache- tomcat-v/lib/

這應該可以解決你的問題
