我安装的jivedon的版本是2.5,我用的tomcat5.0+mysql4.1,我一路上下来,安装安装的提示,都没有错误,可是到了安装测试的第3步,测试数据库连接的时候，提示出错:数据库连接不能建立。打开日志文件"jiveHome\logs\DefaultConnectionProvider.log" 查看错误信息然后返回修正错误。日志里消息:--->Attempt (1 of 5) failed to create new connections set at startup:
java.sql.SQLException: Communication failure during handshake. Is there a server running on localhost:3306?
Will try again in 10 seconds...
--->Attempt (2 of 5) failed to create new connections set at startup:
java.sql.SQLException: Communication failure during handshake. Is there a server running on localhost:3306?
我在mysql下,show tables;能显示出所有的表,就是不知道为什么不能连接上mysql,写了个测试的jsp文件,证明是可以连接数据库的.
真的不知道是为什么,请大家帮忙解决,多谢!
