Tomcat 8启动中缺少Jar文件 [英] Jar files missing in tomcat8 startup

问题描述

我目前正在从事云迁移活动. 我们在云服务器中安装了一个新的"Apache Tomcat/8.0.43"，并将war文件从本地转移到了云中. 启动tomcat服务器时，出现以下错误:

I am currently working on cloud migration activities. We have installed a new "Apache Tomcat/8.0.43" in cloud server and transferred the war files from local to cloud. while starting the tomcat server I’m getting below error :

警告[localhost-startStop-1] org.apache.tomcat.util.scan.StandardJarScanner.scan无法从类加载器层次结构扫描[文件:/usr/share/java/tomcat8/gdk_custom.jar] java.io.FileNotFoundException:/usr/share/java/tomcat8/gdk_custom.jar(没有这样的文件或目录)

Similary，我在下面的jars中得到FileNotFoundException:

 java.io.FileNotFoundException: /usr/share/java/tomcat8/orai18n-tools.jar (No such file or directory)

请帮助我解决此问题.

推荐答案

通常，JAR应该保存在tomcat的lib目录中，而您可以scanAllDirectories.看看 JARScanner (有关conf/context.xml)，并尝试使用值true的所有JarScanner属性.

Generally JARs should be kept in tomcat's lib directory, rather you can scanAllDirectories. Have a look at JARScanner ( its about conf/context.xml ) and try all attributes of JarScanner with value true.
