Question

目前我的项目正在linux服务器上运行，现在我在jdk5中编写了jdk版本jdk5到jdk8所以我该怎么办？

我应用了以下步骤： 1）我跟着文档库部署，所以我在apache2.27 / conf / httpd_vhost.conf文件和worker.properties中更改为我最新的编译（JDK8）位置目录。

httpd_vhost.conf：

<VirtualHost *:80>
 ServerAdmin 
 DocumentRoot /usr/local/ProjectJ8/demoregserver
 ServerName  
 DirectoryIndex      index.html
    ScriptAlias /cgi-bin "/usr/local/apache2.2.27/cgi-bin/"
    Alias /demoregserver "/usr/local/ProjectJ8/demoregserver"
 <Directory "/usr/local/ProjectJ8/demoregserver">
     Options FollowSymLinks -Indexes
    AllowOverride All
 </Directory>
            <Location "/demoregserver/WEB-INF/">
            </Location>

            <Location "/demoregserver/META-INF/">
            </Location>

JkMount /demoregserver/servlet/* wsworker
JkMount /demoregserver/*.jsp wsworker
JkMount /demoregserver/kaptcha.jpg wsworker

 #AddType application/x-httpd-php .php

   # RewriteEngine   On
   # RewriteLog "logs/rewrite.log"
   # RewriteLogLevel 10

   # RewriteCond %{REQUEST_URI} .rpm
   # RewriteCond ${tokenize:%{REMOTE_ADDR}%{QUERY_STRING}} !^$
   # RewriteRule ^(.*)$ $1?${tokenize:%{REMOTE_ADDR}} [R,L]


CustomLog           demoregserver_access_log common
CustomLog           demoregserver_referer_log referer
CustomLog           demoregserver_agent_log agent

2）我还更改了tomcate / conf / server.xml和workder.properties。在worker.properties中更改java_home = / usr / local / jdk1.8.0_101

server.xml：

<Context path="/demoregserver"
                    docBase="/usr/local/ProjectJ8/demoregserver"
                    debug="0"
                    crossContext="false" >
            </Context>

我使用来自不同项目的特定Url调用此项目并收到此错误：

我发现这个错误500：

HTTP错误500内部服务器错误引言

Web服务器（运行Web站点）遇到意外情况，导致客户端（例如您的Web浏览器或CheckUpDown机器人）无法满足请求访问请求的URL的请求。

这是Web服务器生成的“全能”错误。基本上出了问题，但服务器在响应客户端时不能更具体地说明错误情况。除了通知回客户端的500错误之外，Web服务器还应生成某种内部错误日志，其中提供了更多错误的详细信息。由Web服务器站点的操作员来定位和分析这些日志。（最近更新时间：2013年10月）修复500错误 - 一般

此错误只能通过修复Web服务器软件来解决。这不是客户端问题。由Web服务器站点的操作员来定位和分析日志，这些日志应提供有关错误的更多信息。

如何在linux中升级当前项目的Java版本？
