來自Eclipse服務器超時的Tomcat7

我正在運行tomcat7表單Eclipse，並且還確保Eclipse和Tomcat都使用jdk-1.7.0。服務器說「超時。服務器花了超過45秒啓動」。來自Eclipse服務器超時的Tomcat7

當我在eclipse中爲我的項目更改JDK時發生錯誤，但我在運行配置中將其更改爲相同的JDK。 PS：當我通過終端從eclipse外部啓動tomcat7時，它工作正常，但是當我嘗試在Eclipse內引導它時，它會拋出錯誤。

完整的錯誤如下

你在Tomcat的日誌中看到了什麼？服務器是否在超過45秒後啓動，或者有任何問題？ –

它不斷給我在控制檯上面顯示的錯誤。奇怪的是，如果我從外部eclipse啓動tomcat，它工作正常。但是當我嘗試運行eclipse的服務器時，它會拋出這個錯誤。 – Karthik

您是否嘗試過增加服務器超時時間？ – agpt

如果遷移到另一個JDK是唯一的變化和項目在獨立運行Tomcat，那麼問題是，您的Eclipse /項目JRE版本是從Tomcat的JRE版本不同。

它應該是一樣的。

編輯（後問題更新）：

請看this question。 Tomcat類路徑中不應該有任何冗餘庫。

還要確保你沒有觸及任何servlet特定的庫，它們應該被放置在Tomcat/lib並且只能在那裏（沒有移動或複製）。

此外，您的所有第三方庫應放置在您的web應用程序的/WEB-INF/lib，而不是其他位置。

tomcat7和eclipse JRE都指向java7-openjdk-amd64。還有什麼我需要的嗎？ – Karthik

在出現新的細節後，我正在編輯我的答案。 –

原來tomcat 7缺少一個servlet-api jar。我重新安裝它，它工作正常。再次感謝！ – Karthik
