我想问一下,一个jsp的网站首页是用servlet通过jsp生成静态页面,运行环境是linux+jsp+mysql,在服务器的tomcat的文件夹下的logs日志文件怎么记录着如上错误呢??到底什么原因引起的???应该怎么解决呢??

怎么没人看吗??

为什么一报这个错网站的访问速度就很慢~mysqld进程占用cpu的资源就很高呢??

估计你的配置有问题，不过具体什么问题我也看不出来，帮你顶下

[benma0520]

你看看你是不是把MYSQL连接后，没有释放。

[bear88]

顶~~

为什么每天早上8,9点钟tomcat就报StandardContext[/manager]HTMLManager: list: Listing contexts for virtual host 'localhost'这个错呢,接着网速很慢?然后过了这个时间段就恢复正常了呢?

2007-02-27 15:48:30 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
java.lang.StringIndexOutOfBoundsException: String index out of range: 10
at java.lang.String.substring(String.java:1441)
at org.apache.jsp.newsmode_jsp._jspService(newsmode_jsp.java:221)

答案是:
newsmode_jsp 的221行有一个substring的方法,这个方法引发了一个高危的JVM异常StringIndexOutOfBoundsException;

StringIndexOutOfBoundsException异常属于数组越界,一般这情况Tomcat会进入假死机,所有运作"停止",情况严重会引发Out of Memery(OOM);

建议:
到该网页修改一下那Substring的方法,加一个If限一下长度.
