我的EC版本是3.2，tomcat版本是5.5.26，安装配置好后在EC中启动TOMCAT没有问题，但新建JSP文档时无法编辑，还有打开JSP文档时出错，在网上读了很多文档发现可能是插件问题（我当时用emf-sdo-runtime-2.0.0，lomboz.301，tomcatPlugin3.1.0）于是下了lomboz-wtp-emf-gef-jem-3.1.2与tomcatPluginV31。用之前的办法把相应的文件复制到相应的位置，再重启EC，启动画面变成了橙色，但随后弹出窗口说发现错误，打开窗口所说的文档看了一下却不知所云，唯有在此向各位求教。
相应文档说明如下：

------解决方案--------------------
你使用那种all in one的版本吧！
比如
wtp + eclipse http://download.eclipse.org/webtools/downloads/
myeclipse + eclipse
免得有插件兼容问题！
