小编All*_*sen的帖子

我正在使用Apache Derby嵌入式数据库在Maven项目中进行单元测试.不幸的是,每当我运行测试时,我最终都会derby.log在项目的根目录中找到该文件.数据库本身是在target目录(jdbc:derby:target/unittest-db;create=true)中创建的,因此这不是问题.在查阅参考指南之后, 我尝试logDevice在JDBC url(jdbc:derby:target/unittest-db;create=true;logDevice=/mylogs)上设置参数,但这似乎是针对不同的日志,因此derby.log仍然会出现.

任何帮助深表感谢.

符合这个问题:如何获得线程的堆栈跟踪

我想知道是否有人可以指出有关解释提取的Java线程堆栈的信息jstack.

我的情况是我有一个在GlassFish v2.1.1上运行的Java EE 5应用程序,它定期挂起(每天至少2-3次).要让它再次运行,我必须杀死Glassfish进程并再次启动域.应用程序通常会变得越来越慢,直到它最终完全挂起.一旦挂起,我就无法获得线程堆栈.我已经能够获得一个线程堆栈,因为它越来越慢,但我看不到找到问题或挂起的线程.

这是最新的线程转储:http://issues.i2m.dk/attachments/66/threadstack.201103211046.txt
