警告和錯誤在Tomcat的6啓動

Question

我是新來的Tomcat，並一直負責在Eclipse在Tomcat中6/Java的6

遷移的Tomcat 5/1.4的Java應用程序在Tomcat 6啓動時總是收到多個警告信息，如：

No rules found matching 'Server/GlobalNamingResources/ResourceParams/parameter/value'. 6 août 2012 14:49:32 org.apache.tomcat.util.digester.Digester endElement (50 times or so...)

然後

[SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:MyProject' did not find a matching property. 6 août 2012 14:49:32 org.apache.tomcat.util.digester.SetPropertiesRule begin

然後

The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\METIER\MES\java\jdk1.6.0_11\bin; [+ multiple different paths] 6 août 2012 14:49:32 org.apache.coyote.http11.Http11Protocol init

然後

Could not get url for /javax/servlet/jsp/resources/jsp_2_1.xsd 6 août 2012 14:49:32 org.apache.catalina.startup.DigesterFactory register

然後，勿庸置疑，在Web應用程序負載（）異常

我想這個問題源於的Tomcat的配置文件，但我不明白到底是什麼是上述每個警告/錯誤的原因。例如，在server.xml文件中，全局命名資源看起來是正確定義的，所以我應該查找缺少的資源參數塊，或文件中的某種語法錯誤，或缺少.jar或... ？

任何建議歡迎！

Answer 1

這裏的基本問題是，你不能簡單地把一個Tomcat 5.5 server.xml文件，放到Tomcat 6，並期望它沒有任何改變的工作。您需要閱讀Migration Guide等。最好的策略是從Tomcat附帶的server.xml開始，並根據您配置的以前版本進行配置所需的任何修改。這通常意味着<Connector>和<Resource>的定義。請注意，您不應該在server.xml中定義<Context>元素，不再需要。

還有一點需要注意：如果您要升級到不同的主要版本的Tomcat，爲什麼不直到Tomcat 7.0？

No rules found matching 'Server/GlobalNamingResources/ResourceParams/parameter/value

<Resource>元素不再接子元素稱爲<parameter>等取而代之的是，所有的參數轉換爲<Resource>元素的屬性。

[SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' ...

<Context>不支持「source」屬性：Eclipse正在添加它，它不應該在那裏。請注意，這只是一個警告：Tomcat（和你的web應用程序）將會啓動，儘管有這個消息。

您還沒有編譯Tomcat的本地庫，但你已經配置了AprLifecycleListener，它試圖加載這個庫。如果你想使用APR，去get it and compile it。如果你不需要它或需要它，請禁用AprLifecycleListener（或者只是忽略警告消息，這不會傷害任何東西）。如果您使用Tomcat進行SSL終止，則使用APR是一個非常好的主意，因爲APR比SSL的JSSE具有更高的SSL性能，如果您需要這樣的事情，則APR支持FIPS模式。即使您未使用SSL，APR連接器也會比BIO連接器的性能好得多。

我不確定我可以幫你做那個。如果沒有完整的堆棧跟蹤或其他信息（如文件中提到的URL），我們無法提供幫助。
