找不到Tomcat類，並在路徑WEB-INF \ lib中有類

Question

我從服務器複製了一個應用程序，然後部署在Tomcat6上（與服務器相同），但我總是得到錯誤！我試圖重新安裝Tomcat，但錯誤仍然是一樣的。

    desc:there are the classes that could not found by tomcat still in the path /web_inf/lib 

問題1：這有什麼錯呢？

問題2：error1和error2之間是否有任何關係？

確定這是競爭堆棧跟蹤

Answer 1

問題1：這有什麼錯呢？

第一個錯誤看起來像是web應用程序或其配置中的錯誤。 Tomcat報告說，當web應用程序關閉時，某些事情（例如，某個servlet）沒有正確整理。如果這個問題沒有解決，在幾次webapp重啓之後，你的web服務器很可能會耗盡內存。

第二個錯誤是抱怨無法找到某個類。這可能是某種Web服務器或Web應用程序配置錯誤。

在這兩種情況下，如果您向我們展示完整的堆棧跟蹤信息，這將有所幫助。

問題2：error1和error2之間是否有任何關係？

可能不是。

挖一點點告訴我，你很可能會發現org.apache.axis.transport.http.AdminServlet名爲axis-x.y.jar或類似的東西，一個JAR文件（見http://findjar.com/class/org/apache/axis/transport/http/AdminServlet.html完整的列表）

爲org.jdom.input.SAXBuilder外觀像一個文件jdom-x.y.jar（請參閱http://findjar.com/class/org/jdom/input/SAXBuilder.html獲取完整列表）

第二個錯誤與您最初報告的錯誤不同，但它仍然是web應用程序中的錯誤。這可能是你第一次錯誤的結果;即它假設servlet正確啓動。

你需要看看你安裝在Tomcat上的webapp，看看Axis和JDOM JAR是否在WEB-INF/lib中。如果沒有，請回到您複製webapp的服務器，然後查看那裏的webapp ......以及服務器的公共庫區域。 （你沒有說你是從哪個服務器複製的...）
