我在部署一个J2EE项目到tomcat6.X的时候MyEclipse报错，

会话数据：eclipse.buildId=unknown

请大家帮我看看问题出在哪里了，感谢！
------解决思路----------------------
看不出什么问题，把工程clean一下，把tomcat的工作空间clean一下，再部署试试
------解决思路----------------------
重启下MyElipse试一试,你这可能是因为部署的webapp没有释放是否重写文件的权限。。。。。
------解决思路----------------------
解决了就好，一般还会配置自己本地的jre，这样也会避免一下版本不统一的问题
