运行时，

[qsl_2010]

tomcat启动后一切正常，可运行期间会偶尔报空指针（时间间隔较长，异常时，应该也是没有操作的），但对程序的正常运行好像没有影响，具体大大们帮看一下。

用的tomcat7吧，是最新的吗，下载最新稳定版的。

是因为你的tomcat在server.xml里配置的有问题，即使域名配置了，也必须要有<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true"></Host>这个localhost配置，不然就会报你那个错，因为这个request请求是很不寻常的才会出现这个错，你配置一个localhst就可以了 www.firstrunner.net
