第一次用nb，本想安个nb作javafx，手痒痒建个javaee试试，花了一天时间都没能运行了一个页面。一上午配置tomcat服务器，说是没有catalina.bat文件，于是各种百度，tomcat可以在nb上面启动了，狂喜，结果一运行jsp页面，又出问题，一直报这个错误：
D:\我的文档\NetBeansProjects\EnterpriseApplication3\EnterpriseApplication3-war\n
bp
roject\build-impl.xml:785: The libs.CopyLibs.classpath property is not set up.
This property must point to
org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part
of NetBeans IDE installation and is usually located at
<netbeans_installation>/java<version>/ant/extra folder.
Either open the project in the IDE and make sure CopyLibs library
exists or setup the property manually. For example like this:
ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar
构建失败 (总时间: 0 秒)
有木有知道怎么回事的？若木有，果断放弃netbeans。
