ITlife365 生活网分享一下解决HTTP Status 500 - Unable to compile class for JSP
首先，百度查了很多，貌似对说这个是自己项目的问题。但是我只是一个index.jsp 页面呀，
于是重新新建。
过程如下：
1、文件问题报错：
HTTP Status 500 - Unable to compile class for JSP:
type Exception report
message Unable to compile class for JSP:
description The server encountered an internal error that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 10 in the jsp file: /index.jsp
Syntax error on token ";", delete this token
7: </head>
8: <body>
9: <h1>JSP Test Pagei on undure public</h1>
10: Today is <%=new java.util.Date() ;%></br>
11: 2014023 :22212: <br/><% out.print("Helloworld"); %>
13:
Stacktrace:
org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:92)
org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:330)
org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:443)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:356)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:334)
org.apache.jasper.compiler.Compiler.compile(Compiler.java:321)
org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:592)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:328)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)
javax.servlet.http.HttpServlet.service(HttpServlet.java:723)
删除index.jsp文件的;后，重启tomcat ,还是报错如下：
HTTP Status 500 - org.apache.jasper.JasperException: Unable to load class for JSP
type Exception report
message org.apache.jasper.JasperException: Unable to load class for JSP
description The server encountered an internal error that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: org.apache.jasper.JasperException: Unable to load class for JSP
org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:161)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:340)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)
javax.servlet.http.HttpServlet.service(HttpServlet.java:723)
于是乎，我把整个文件删除index.jsp，重新插入如下内容：
<html>
<head>
<title>Jsp test title</title>
</head>
<body>
<h1>JSP Test Pagei on undure public</h1>
Today is <%=new java.util.Date()%></br>
<br/><% out.print("Helloworld"); %>
<br/>
<%System.out.println("hello world");%>
</body>
</html>
呵呵，问题解决，不报Unable to load class for JSP了，原来是项目本身的问题。
报了如下的新错误：
HTTP Status 404 - /index.jsp
type Status report
message /index.jsp
description The requested resource is not available.
Apache Tomcat/6.0.37
原来是server.xml 文件配置错误了。在Host 下添加<Context 的内容即可。具体如下：
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
<Context path="" docBase="" debug="0" reloadable="true" crossContext="true"/>
</Host>
重启可以访问了。
