最近在研究Servlet3.0,它是JavaEE6.0规范中的一部分
而Servlet3.0对服务器是有要求的,比如Tomcat7+(而Tomcat7.0要求JDK6+,即编译级别应该是6+)
但我一直使用的MyEclipse6.5不支持Tomcat7,可也不能为了这个就去装一个MyEclipse8.0啊
好吧,还是像当初我用TongWeb5.0的方式一样,自己DIY一下吧
1)下载Tomcat7 2)由于我已经配置了tomcat6,为了同时拥有tomcat6和tomcat7的环境,所有我们在MyEclipse的Tomcat5.x里配置tomcat7 MyEclipse-->Window-->Preferences-->MyEclipse Enterprise Workbench-->Servers-->Tomcat-->Tomcat5.x Tomcat5.x-->Enable Tomcat5.x-->Tomcat home directory-->D:Developapache-tomcat-7.0.41 Tomcat5.x-->JDK-->Tomcat JDK name-->jdk1.6.0_45 3)第二步配置完,在MyEclipse6.5的Servers视图里启动Tomcat5.x(实际为tomcat7.0.41)会发现弹出一个对话框 Could not find the main class: org.apache.catalina.startup.Bootstrap. Program will exit. 同时MyEclipse6.5控制台会输出下面的异常信息 java.lang.NoClassDefFoundError: org/apache/juli/logging/LogFactory at org.apache.catalina.startup.Bootstrap.<clinit>(Bootstrap.java:60) Caused by: java.lang.ClassNotFoundException: org.apache.juli.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 1 more 4)所以我们还要修改一下 Tomcat5.x-->Paths-->Append to classpath-->把D:Developapache-tomcat-7.0.41bintomcat-juli.jar加进去-->Apply-->OK 然后再启动Tomcat5.x(实际为tomcat7.0.41)会发现启动成功!!浏览器访问http://127.0.0.1:8080/成功!!
下面是控制台输出
