eclipse支持8.0的tomcat,可以配置tomcat8.5版本吗?

3个回答

不可以的,低版本不能搭配高版本的

可以的,不过要修改Tomcat配置文件里的版本号,网上有教程的,毕业设计改过所以还有点印象。

可以,只要在eclipse中添加server tomcat 8选择就可以。只要保证eclipse支持的版本,就没问题。
最新的eclipse 支持tomcat 9 。

eclipse无法安装Tomcat8.5版本
![图片说明](https://img-ask.csdn.net/upload/201709/05/1504590194_231743.png) 重新安装了个Tomcat然后在eclipse中无法添加8.5的tomcat,求大神告知. workspace下的org.eclipse.wst.server.core.prefs和org.eclipse.jst.server.tomcat.core.prefs我已经删除还是添加不了Tomcat 原因: Tomcat版本比较特别,无法与eclipse绑定,选择8.5提示: The Apache Tomcat installation at this directory is version 8.5.12. A Tomcat 8.0 installation is expected. 解决方案:http://blog.csdn.net/change518/article/details/52577132 http://jingyan.baidu.com/album/48a42057f8dfafa92525044d.html

eclipse tomcat 无法配置runtime environment
不懂 eclipse 加载插件的原理 按网上说的去 workspace\.metadata\.plugins\org.eclipse.core.runtime\.settings 下删除 1. org.eclipse.wst.server.core.prefs 2. org.eclipse.jst.server.tomcat.core.prefs(我的环境下找不到此文件) 环境 eclipse: Neon.1a Release (4.6.1) (安装路径:~/) tomcat:apache-tomcat-8.5.6-windows-x64 (安装路径:C:/) jdk:Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)(安装路径:C:\Program Files\Java\jdk1.8.0_101) tomcat任何一个版本都选择不了,path里面也设置了tomcat的bin路径 ![图片说明](https://img-ask.csdn.net/upload/201610/29/1477700894_603245.png)
求问,为啥把tomcat6.0换成tomcat7.0、tomcat8.0就报错了呢?
开发工具是用的是MyEclipse14,jdk1.6和1.8,使用tomcat6没有任何问题,但是换了tomcat7和tomcat8都出错 Tomcat7:在谷歌浏览器输入http://localhost:8080/test/报错:The requested resource is not available.但是此时Console没报错。 tomcat8:Console报错:java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.FilterDispatcher 在谷歌浏览器输入http://localhost:8080/test/出错: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. 求问该如何解决呢?

springboot 多模块打包war,tomcat启动提示找不到配置文件

Java springboot项目,使用javax.mail的邮件发送功能,提示javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed
Java项目:框架用的是spring boot。 本地运行环境:开发工具:eclipse;jdk版本:1.8.0_171; 功能描述:用户登陆时如果使用邮箱登录,会给用户邮箱发送一个验证码。用户通过【邮箱+验证码】进行登录。 问题描述:这个邮箱登录功能是几个月之前就已经开发完成了,并且是可成功运行的。 这几天闲着没事去点这个邮箱登录的时候发现以下问题。 不知道大家有没有遇到过这个问题,希望大家能帮忙解答一下。谢谢各位啦 ``` javax.mail.MessagingException: Could not connect to SMTP host: smtp.vip.163.com, port: 465; nested exception is: javax.net.ssl.SSLHandshakeException:

如何在高版本的tomcat下运行低版本的项目
如何在配置有高版本tomcat的Eclipse内将低版本的项目抛弃来,比如说我的Eclipse配置tomcat是9.0,我得怎么将8.0的项目抛弃来,直接导入是这样的。 ![图片说明](https://img-ask.csdn.net/upload/201906/07/1559897010_773372.png) 打开项目的xml,Tomcat9.0跑出来的版本是version = "4.0",而需要导入的项目版本version = "2.5"。求助前辈们如何破?

tomcat7.0运行报错:No rules found 'Server/Service/...
tomcat7.0下运行工程报错:No rules found matching 'Server/Service/Engine/Host/Resource' 我的web工程中有个配置: 在contextConfigLocation中配置加载app-context.xml 然后在app-context.xml文件中有个配置: < jee:jndi-lookup id="mDS" jndi-name="java:comp/env/jdbc/MDS" /> 然后我在ecplice的service标签下配置tomcat后,修改tomcat的context.xml文件,在< Context中添加了一个Resource配置如下: < Resource driverClassName="org.gjt.mm.mysql.Driver" maxActive="8" maxIdle="4" name="jdbc/MDS" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/mdb?characterEncoding=UTF-8" username="root" password="root" /> 其余就没有配置了,然后再启动tomcat的时候就报了如下的错误: 2014-12-5 21:40:23 org.apache.catalina.core.AprLifecycleListener init 信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.6.0_43\bin;C:\Windows\Sun\Java\bin;C:\Windows\system32;C:\Windows;C:/Program Files/Java/jdk1.6.0_43/bin/../jre/bin/server;C:/Program Files/Java/jdk1.6.0_43/bin/../jre/bin;C:/Program Files/Java/jdk1.6.0_43/bin/../jre/lib/amd64;C:\Program Files\Java\jdk1.6.0_43\bin;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;D:\software\apache-maven-3.2.1\bin;D:\tools\SVN\bin;D:\tools\MYSQL\MySQL Utilities 1.4.4\;D:\tools\MYSQL\MySQL Utilities 1.4.4\Doctrine extensions for PHP\;.;;D:\eclipse;;.;;. 2014-12-5 21:40:23 org.apache.tomcat.util.digester.Digester endElement 警告: No rules found matching 'Server/Service/Engine/Host/Resource'. 2014-12-5 21:40:23 org.apache.tomcat.util.digester.SetPropertiesRule begin 警告: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:m' did not find a matching property. 按照网上的各种方法试了都不行,请为下各位大神是什么原因,我用的tomcat7.0,jdk是jdk1.6.0_43,ecplise版本是Kepler Service Release 2,实在是黔驴技穷了,求帮助~~
eclipse+tomcat9的web.xml已经用了4.0的servlet和约束,每次保存还是卡很久
``` <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0" metadata-complete="true"> </web-app> ``` 约束是从tomcat的examples里的web.xml找来的,创建web工程的时候也确认了是4.0,jdk是1.8.0_201,每次保存web.xml还是要卡很久 把网断了或者打开eclipse后不打开project explorer的话,修改web.xml也不,这是为什么
关于tomcat和jdk的问题
最近jdk10发布了,本人想项目中的jdk,现发现,tomcat8配置jdk10 可以正常运行,环境变量也是java10我也查看了官网说是tomcat8能够支持jdk8或以上的jdk版本。 但是问题来了: 我安装了最新版本的eclipse 4.7.3a然后也配置了相应的java10的相关参数,运行tomcat8服务就提示 -Djava.endorsed.dirs=/xxx/apache-tomcat-8.0.51/endorsed is not supported. 请资深java高手作答同样的tomcat为什么直接运行是可行的,但是在eclipse下又不可行了? PS:eclipse java compiler还有tomcat的Server runtime的JRE都设置成jdk10
eclipse tomcat 配置问题
求各位大神解决一个问题 用的是eclipse3.7 tomcat7 jdk1.6 大体是按照这个步骤做的 <http://wenku.baidu.com/link?url=4f8RcEfdjCfuIihOEe288xDV2c977fwj3ROuOE2SWob5QvU3YVVOliNSOTuG3e0XYMzH-rJvXPVlDtlik1pJv-Sf7AUWsTRNzmgilq_uoCW> 结果就是.... ![CSDN移动问答][1] 1.首先点那个tomcat图标 下面控制台显示已经成功启动 ![CSDN移动问答][2] 2.但是servers毫无反应 ![CSDN移动问答][3] 3.运行时状态也一样,无法通过服务器运行 ![CSDN移动问答][4] 4.本地计算机服务管理也显示 tomcat 没有启动 ![CSDN移动问答][5] 5.但是,打开localhost的时候,居然打开了 所以,结果就是,eclipse 可以启动tomcat 但是自己的程序却不能跑,而且在系统服务中并未显示tomcat启动,但的确能打开localhost。。凌乱了 求高手指点下 [1]: http://img.my.csdn.net/uploads/201311/19/1384860703_8397.png [2]: http://img.my.csdn.net/uploads/201311/19/1384860707_9771.png [3]: http://img.my.csdn.net/uploads/201311/19/1384860708_9293.png [4]: http://img.my.csdn.net/uploads/201311/19/1384860708_4231.png [5]: http://img.my.csdn.net/uploads/201311/19/1384860709_4992.png

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
