I have a Spring-based Application that was successfully running under Tomcat 5.5.
I've attempted to move it to JBoss 4.0.5, but it's having problems using the JSP Expression Language (EL). I made sure that I have the most recent JSTL 1.1 jstl.jar and standard.jar files. In the web.xml file I declare: <web-app xmlns="http://java.sun.com/xml/ns/j2ee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"; version="2.4"> In the JSP page, I have the following: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %> <%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"; %> But it continues to have a problem. Spring says that it found the JSP 2.0 ExpressionEvaluator, but it can't find: org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager I see this method in the JSTL version 1.0 standard.jar file, but not in the version 1.1 file. How can I figure out why and from where it is looking for that? 2007-04-30 16:40:36,511 INFO [STDOUT] 2007-04-30 16:40:36,511 DEBUG [org.springframework.web.servlet.view.InternalResourceViewResolver] - Cached view [index] 2007-04-30 16:40:36,511 INFO [STDOUT] 2007-04-30 16:40:36,511 DEBUG [org.springframework.web.servlet.DispatcherServlet] - Rendering view [org.springframework.web.servlet.view.JstlView: name 'index'; URL [/WEB-INF/jsp/spring/index.jsp]] in DispatcherServlet with name 'oes' 2007-04-30 16:40:36,511 INFO [STDOUT] 2007-04-30 16:40:36,511 DEBUG [org.springframework.web.servlet.view.JstlView] - Rendering view with name 'index' with model null and static attributes {} 2007-04-30 16:40:36,761 INFO [STDOUT] 2007-04-30 16:40:36,761 INFO [org.springframework.ui.context.support.ResourceBundleThemeSource] - Theme created: name 'theme', basename [theme] 2007-04-30 16:40:36,761 INFO [STDOUT] 2007-04-30 16:40:36,761 DEBUG [org.springframework.web.util.ExpressionEvaluationUtils] - Found JSP 2.0 ExpressionEvaluator 2007-04-30 16:40:36,761 INFO [STDOUT] 2007-04-30 16:40:36,761 DEBUG [org.springframework.util.ClassUtils] - Class [org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager] or one of its dependencies is not present: java.lang.ClassNotFoundException: org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager 2007-04-30 16:40:36,776 INFO [STDOUT] 2007-04-30 16:40:36,776 DEBUG [org.springframework.context.support.ReloadableResourceBundleMessageSource] - Loading properties [oesweb.properties] 2007-04-30 16:40:36,776 INFO [STDOUT] 2007-04-30 16:40:36,776 DEBUG [org.springframework.context.support.ReloadableResourceBundleMessageSource] - No properties file found for [/WEB-INF/strings/oesweb_en] - neither plain properties nor XML 2007-04-30 16:40:36,776 INFO [STDOUT] 2007-04-30 16:40:36,776 DEBUG [org.springframework.context.support.ReloadableResourceBundleMessageSource] - Loading properties [oesweb_en_US.properties] 2007-04-30 16:40:36,854 INFO [STDOUT] 2007-04-30 16:40:36,854 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[jsp]] - Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at org.apache.jsp.WEB_002dINF.jsp.spring.index_jsp._jspService(index_jsp.java:1 31) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:3 34) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Application FilterChain.java:252) ..
