Ubuntu 12.04，Tomcat7，NetBeans 7 - 獲取java.lang.NoClassDefFoundError：Lorg/slf4j/Logger;

我有一個Java EE項目，在我們的遠程服務器和tomcat容器之一中工作正常。無論何時我們想對應用程序進行一些更改，我們都會在本地計算機上執行該操作，然後構建它並將ws.war複製到tomcat根目錄中的服務器上。Ubuntu 12.04，Tomcat7，NetBeans 7 - 獲取java.lang.NoClassDefFoundError：Lorg/slf4j/Logger;

我想設置本地開發環境，我可以對應用程序進行更改。我有我的項目源文件。我下面的事情：

1. Install tomcat7 in my home directory and set up `CATALINA_HOME` 
    environment variable in `.bashrc` 
2. Install oracle-java and setup JAVA_HOME in `.bashrc` 
3. Install Netbeans 7 and import the project in it. 
4. Since, the Netbeans came with `glassfish` as default server, I added 
    a tomcat as the server with proper configuration. 
5. I try running the application (through Netbeans), and I receive the following error:

我做了一些研究，我發現有一些版本不兼容與1.6.1版和slf4j以前的版本。但是，我無法找到解決辦法。

任何幫助表示讚賞。我的POM.xml如下：

您可以發佈'mvn dependency：tree '你的項目命令？ – Ceki

首先它有點奇怪你有sl4fj-log4j12但不是實際的log4j依賴本身。通常你需要這個，因爲sl4fj只是一個門面。嘗試添加類似：

<dependency> 
    <groupId>log4j</groupId> 
    <artifactId>log4j</artifactId> 
    <version>1.2.17</version> 
</dependency>

其次，你可能要檢查什麼在你的生產服務器的內部$ TOMCAT_HOME/lib文件夾中。如果有任何額外的瓶子放置在默認的頂部，您需要將其複製到您的本地環境（或重組部署，使所有內容都包含在您的應用程序中）

好的，會嘗試，並會讓你知道。 – VaidAbhishek

現在，我越來越...由...引起：java.lang.NoClassDefFoundError：Lorg/slf4j/Logger; – VaidAbhishek

聲明對org.slf4j的依賴：slf4j-log4j12將引入org.slf4j：slf4j-api以及log4j：log4j。因此，通常不需要分別聲明org.slf4j：slf4j-api或log4j：log4j。 – Ceki
