可能你是开机时，tomcat自动启动了，你没有把它关掉，在eclipse上，你又启动了tomcat.建议不要开机启动tomcat.
端口占用
说明有另外一个程序在8080，可能还是你的tomcat
打开进程杀掉把
sqlwriter看上去不是个很重要的东西，
如果这个很重要的话，tomcat换一个端口吧
tomcat conf下更改server文件下的
[code="xml"] maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" /> [/code]
其中port就是端口值 把8080改成你需要就可以了，别改错了
