tomcat5.5.17+jstl1.2+servlet2.5+jsp2.1配置
tomcat5.5.17+jstl1.2+servlet2.5+jsp2.1配置
在此我使用的環境是:
tomcat5.5.17
jstl1.2
servlet2.5
jsp2.1
我以一個簡單的例子hello1來說明吧,發布工程時最重要的就是目錄結構了,hello1是根目錄,放在tomcat中的webapps里,先看看目錄結構:
hello1\index.jsp
hello1\response.jsp
hello1\WEB-INF\lib\javaee.jar
hello1\WEB-INF\lib\jsf-api.jar
hello1\WEB-INF\lib\jsf-impl.jar
hello1\WEB-INF\lib\jstl-1.2.jar
hello1\WEB-INF\web.xml
如果你按照以上目錄發布工程,拋出以下異常:
(1) java.lang.NoClassDefFoundError: javax/el/ExpressionFactory
(2) 或打開頁面后顯示:
HTTP Status 404 - /hello1/
type Status report
message /hello1/
description The requested resource (/hello1/) is not available.
Apache Tomcat/5.5.17
<html> <c:if test="${fn:length(param.username) > 0}" > <web-app xmlns=" xmlns:xsi=" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee web-app_2_5.xsd" <jsp-config>

則將javaee.jar包再copy一份放在tomcat目錄的common\lib下就不會了。
關于用到的javaee.jar、jsf-api.jar、jsf-impl.jar、jstl-1.2.jar這四個包可以通過myeclipse中獲得,如果你安裝了myeclipse5.5的話,我安裝的是MyEclipse 5.5.1 GA,這四個包的所在的目錄是:MyEclipse 5.5.1 GA\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_5.5.1\data\libraryset\EE_5\
到此,再給出具體的文件代碼吧。
(1) hello1\index.jsp
<%@ taglib uri="<%@ taglib uri="
<head><title>Hello</title></head>
<body bgcolor="white">
<h2>Hello, my name is Duke. What's yours?</h2>
<form method="get">
<input type="text" name="username" size="25">
<p></p>
<input type="submit" value="Submit">
<input type="reset" value="Reset">
</form>
<%@include file="response.jsp" %>
</c:if>
</body>
</html>
(2) hello1\response.jsp
<h2><font color="black">Hello, ${param.username}!</font></h2>
(3) hello1\WEB-INF\web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
version="2.5">
<jsp-property-group>
<display-name>hello1</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
<scripting-invalid>false</scripting-invalid>
<is-xml>false</is-xml>
<!-- <include-prelude>/template/prelude.jspf</include-prelude> -->
<!-- <include-coda>/template/coda.jspf</include-coda> -->
</jsp-property-group>
</jsp-config>
</web-app>
成功之后頁面顯示為:
Hello, my name is Duke. What's yours?
Hello, afdfadsfads!
