..............


无法获取数据库链连。应如何设置数据库呢?
按网上设置也无法解决。
检查程序.....若是程序有问题，那一运行起就应该出错的。
但出错是在两天后。
应用服务器：tomcat
数据库:mysql5.0
框架：strut+hibernate

试一试，在WIN环境变量中设置： _JAVA_SR_SIGNUM=12,

若Linux下用 export _JAVA_SR_SIGNUM=12,

基本就可以解决.

谁有解决方法啊？郁闷啊

2 楼 100Air 2007-03-12  

很笨的解决方法：目前只用一个后台程序每隔5个小时链接数据库......郁闷啊!!!(这种情况是数据库相隔一段时间没有链接时，它自动切断所有程序链接)。

1 楼 Ruby&Rails 2007-02-06  

我的情况好像和楼上仁兄的一样，大家有没有解决的办法？
