我正在将旧版 Web 应用程序移植到 JBOSS AS7。该代码在 Tomcat 6 或 JBOSS 5 中运行良好。该应用程序使用 struts-1.2.9，我们还定义了一些自定义 taglib，这给我带来了问题。

我有一个定义 taglib 的 mainScripts.jsp 文件

<%@ taglib uri="/WEB-INF/lib/abtaglib.tld" prefix="abtag" %>

/WEB-INF/web.xml 文件包括以下内容。不确定这是否需要！？

<taglib>
    <taglib-uri>abtags</taglib-uri>
    <taglib-location>/WEB-INF/lib/abtaglib.tld</taglib-location>
</taglib>

当我在 JBOSS AS7 中访问此页面时，我收到以下错误。似乎 jboss web 模块无法访问我的 war 文件中的文件。我怎样才能解决这个问题？

我找到了解决方案。似乎位于 JBOSS 模块 (jbossweb-7.2.0.Final-redhat-1.jar) 中的 Jasper 无法访问位于 /WEB-INF/lib/ 中的我的 tld 文件。相同的代码适用于 JBOSS 5、Websphere 6 和任何版本的 Tomcat。我认为这是一个类加载问题。当我将 tld 文件移动到 jar 文件中的 /META-INF 文件夹中时，它开始工作。我不再需要 web.xml 中的 taglib 引用，因为 tld 文件是自动从 jar 文件 /META-INF 文件夹中提取的。这是最终的代码：

在jsp中声明taglib：

<%@ taglib uri="http://mycompany/abtags" prefix="abtag" %>

将 tld 文件打包到 jar 中：

/WEB-INF/lib/XYZ.jar

XYZ.jar 内容：

/META-INF/abtaglib.tld
/META-INF/MANIFEST.MF

abtaglib.tld 内容

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
  PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
  "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
    <tlib-version>1.0</tlib-version>
    <jsp-version>1.1</jsp-version>
    <short-name>abtag</short-name>
    <uri>http://mycompany/abtags</uri>
    <display-name>XYZ Tag</display-name>
...

我在使用 Jboss 8（Wildfly 8）时遇到了同样的问题。将所有 taglib "*.tld" 文件复制到 META_INF 文件夹中，为我工作。

您应该使用在您的 tld 文件中定义的 URI，并且，是的，在您的 web.xml 中定义它的位置。例如 ：

<%@ taglib uri="http://mycompany/jsp/abtablib" prefix="abtag" %>

如果您使用的是标准标记库，只需将 jar 放入您的类路径并使用正确的 URI。这是一个带有核心 jstl taglib 的示例（将 jstl-1.2.jar 放入您的类路径中）：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
