Re: [Resin-interest] LDAP Connection Pooling
You probably already found this with a google search, but I'll point it out anyway. Sun describes simple pooling for the JNDI/LDAP stuff: http://java.sun.com/products/jndi/tutorial/ldap/connect/pool.html In addition the Spring framework has their own take on LDAP connection pooling: http://www.springsource.org/ldap Disclaimer: I haven't used any of these. -Knut On Fri, Mar 6, 2009 at 10:04 AM, Matt White mwh...@leporidae.net wrote: On Fri, Mar 6, 2009 at 11:48 AM, Scott Ferguson f...@caucho.com wrote: No, Resin doesn't have LDAP pools.
