我正在努力将遗留的Web应用程序移植到JBOSS AS7。代码在Tomcat 6或JBOSS 5中运行良好。该应用程序使用struts-1.2.9,我们还定义了一些定制的taglib,它们给我带来了问题。
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。不确定是否需要这个!?
<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,出现以下错误。似乎jboss web模块无法访问war文件中的文件。我该如何解决这个问题?

我找到了解决方案。似乎Jasper,它位于JBOSS模块(jbossweb-7.2.0.Final-redhat-1.jar)中,无法访问位于/ WEB-INF / lib /中的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文件会自动从jar文件/ META-INF文件夹中获取。这是最终的代码:
在jsp:
中声明taglib<%@ taglib uri="http://mycompany/abtags" prefix="abtag" %>
打包的tld文件包含一个jar:
/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>
...

我和Jboss 8(Wildfly 8)有同样的问题。复制了所有taglib&#34; * .tld&#34;文件到META_INF文件夹,对我有用。
答案 2 :(得分:0)
您应该使用tld文件中定义的URI,是的,在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taglib,只需将jar放入类路径并使用正确的URI即可。 以下是核心jstl taglib的示例(在类路径中放置jstl-1.2.jar):
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
