未找到jboss as7 tld

Question

我正在將遺留的Web應用程序移植到JBOSS AS7。該代碼在Tomcat 6或JBOSS 5中工作正常。該應用程序使用struts-1.2.9，並且我們還定義了一些自定義的taglib，它們給我帶來了問題。

我有一個定義標籤庫

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

的/WEB-INF/web.xml文件包括以下內容的mainScripts.jsp文件。不知道這是否需要！？

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

當我在JBOSS AS7中訪問此頁面時，出現以下錯誤。看來，jboss Web模塊不能訪問我的war文件中的文件。我怎樣才能解決這個問題？

Answer 1

我找到了解決辦法。看來在JBOSS模塊（jbossweb-7.2.0.Final-redhat-1.jar）中的Jasper無法訪問位於/ WEB-INF/lib /中的我的tld文件。相同的代碼在JBOSS 5，Websphere 6以及任何版本的Tomcat中均可用。我認爲這是一個類加載問題。當我將我的tld文件移動到jar文件中的/ META-INF文件夾中時，它開始工作。我不再需要web.xml中的taglib引用，因爲tld文件是從jar文件/ META-INF文件夾自動提取的。下面是最終代碼：在JSP中

申報的taglib：

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

打包TLD文件insde一個jar：

/WEB-INF/lib/XYZ.jar 

XYZ.jar內容：

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

abtaglib.tld content

<?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> 
... 

Answer 2

您應該使用在您的tld文件中定義的URI，並且是，在web.xml中定義它的位置。例如：

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

如果您使用的是標準的標籤庫，只是把罐子在你的classpath並使用正確的URI。 這裏是與核心JSTL標籤庫的例子（把JSTL-1.2.jar在類路徑）：

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

Answer 3

我和Jboss 8（Wildfly 8）有同樣的問題。將所有taglib「* .tld」文件複製到META_INF文件夾中，爲我工作。
