我創建的Servlet這個原型:http://maciejwalkowiak.github.io/servlet3-maven-archetype/的Tomcat無法編譯類JSP Servlet 3.0中
mvn archetype:generate \
-DarchetypeGroupId=pl.maciejwalkowiak \
-DarchetypeArtifactId=servlet3-webapp-archetype \
-DarchetypeVersion=1.0.1
然後我添加的index.jsp到的src/main/webapp目錄
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>hello, world</h1>
</body>
</html>
時我跑mvn tomcat7:run
和開放http://127.0.0.1/mycontext/index.jsp
此錯誤時:
HTTP Status 500 - Unable to compile class for JSP:
type Exception report
message Unable to compile class for JSP:

有什麼問題?
更新
我使用java8但我已經在我的行家以下Maven編譯配置:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
嘗試清理您的項目。 –
mvn乾淨,但沒有解決 –
