Tomcat 6 vs 7 - lib vs shared / lib - jars only？ [英] Tomcat 6 vs 7 - lib vs shared/lib - jars only?

问题描述

从Tomcat 6升级到Tomcat 7时 - 我们在6上的$ CATALINA_HOME / lib目录中保留了我们想要的类路径上的一些文件 - 在Tomcat 7上移动这两个$ CATALINA_HOME / shared / lib是有意义的。

我们发现jar文件已经过了 - 但是任何不是jar文件的东西 - 例如xml文件等都没有被在shared / lib目录中加载的类。当我们将非jar文件移回$ CATALINA_HOME / lib目录时 - 它们加载到类路径中而没有问题。

我的问题是 - 这是Tomcat 7中类加载器中的错误吗？或者这是预期的行为吗？（未能将$ jar文件从$ CATALINA_HOME / shared / lib加载到类路径中，其方式与从$ CATALINA_HOME / lib加载文件的方式不一致）

操作系统：Windows7

Tomcat版本：7.0.30

Java版本：1.7.0_11

解决方案

我不使用共享库，但根据这个文档： $ b $

请注意，Tomcat 6.0.14 $ CATALINA_HOME / shared / lib目录不存在
。

你需要添加这个，你需要编辑
$ CATALINA_HOME / conf / catalina.properties，以便shared.loader行
看起来像这样shared.loader = $ CATALINA_HOME / shared / lib

When upgrading from Tomcat 6 to Tomcat 7 - we kept a number of files we wanted on the classpath in the $CATALINA_HOME/lib directory on 6 - and it made sense to move these two $CATALINA_HOME/shared/lib on Tomcat 7.

What we've found is that the jar files went across ok - but anything that wasn't a jar file - eg an xml file etc was not picked up by the class loaded in the shared/lib directory. When we moved the non-jar files back to the $CATALINA_HOME/lib directory - they loaded into the classpath without an issue.

My question is - is this a bug in the classloader in Tomcat 7? Or is this intended behaviour? (Failing to load non-jar files onto the classpath from the $CATALINA_HOME/shared/lib in a manner inconsistent to that which loads files from $CATALINA_HOME/lib)

OS: Windows7

Tomcat version: 7.0.30

Java version: 1.7.0_11

解决方案

I don't use shared lib, but according to this doc: http://wiki.apache.org/tomcat/HowTo

Note that Tomcat 6.0.14 the $CATALINA_HOME/shared/lib directory does not exist.

You will need to add this and you will need to edit $CATALINA_HOME/conf/catalina.properties so that the shared.loader line looks like this shared.loader=$CATALINA_HOME/shared/lib
