问题描述
在Java EE项目中，我将所有库从 WAR / WEB-INF / lib 移动到 EAR / lib 。
In a Java EE project, I moved all the libraries from the WAR/WEB-INF/lib to the EAR/lib.
打开JSP，现在我收到此错误：
Opening a JSP, now I get this error:
Stacktraces
org.apache.jasper.JasperException: File "/struts-tags" not found
...........
...........
如何解决这个问题？
推荐答案
将库从WAR移到EAR可能非常有用，例如如果在一个EAR中有多个WAR *，则为了避免库的冗余。
Moving the libraries from the WAR to the EAR may be very useful, e.g. if you have more than one WAR* inside one EAR, to avoid redundancy of libraries.
制作（没有库的WAR）工作，条件是：
To make a Skinny WAR (a WAR without libraries) work, the conditions are:
-
WAR的
META-INF / MANIFEST.MF必须包含链接库的Class-Path属性：
The WAR's
META-INF/MANIFEST.MFmust contain a Class-Path property linking your libraries:
Class-Path: lib/struts2-core-2.3.15.2.jar
lib/xwork-core-2.3.15.2.jar
lib/all_your_libraries_here...
EAR的 application.xml 必须包含：
< library-directory> lib< / library-directory> 。
要在Maven上实现这个条件，不需要在EAR的POM.xml中声明WAR的POM.xml的每个库的依赖关系，可以使用。
To achieve this conditions on Maven, without the need of declaring the dependency of each library of WAR's POM.xml in EAR's POM.xml, you can use this amazing trick.
那说，问题在问题中报告的事实是 TLD 查询仅在WAR上执行，EAR超出范围
。
That said, the problem reported in the question is given by the fact that the TLD lookup is performed on the WAR only, the EAR is out of scope.
解决方案：
从 struts2-core-2.3.xxjar struts-tags.tld c $ c>，并将其置于（每个） WAR / WEB-INF 文件夹。
extract the struts-tags.tld from struts2-core-2.3.x.x.jar, and place it under (each) WAR/WEB-INF folder.
在JSP中：
<%@ taglib prefix="s" uri="/WEB-INF/struts-tags.tld" %>
