Re: [c3p0-users] C3P0Registry mbean is already registered - on redeploy

[Steve W. <swa...@mc...>]

Tom -- Disabling the JMX stuff would be fine. The issue is the  
relationship between Tomcat's classloading scheme and c3p0's use of  
static variables in C3P0Registry. This is something that I'll pay  
more attention to in the next major version of c3p0. But turning JMX  
support off will evade the whole issue for now.

All -- I'm swamped, and have let a lot of c3p0-related correspondence  
go by the last couple of weeks. My apologies. I hope to eat into the  
queue very soon.

     smiles,
        Steve
