Re: tomcat 5.5 and jndi context naming error
I've been trying out many different avenues to make this work and finally found the following bug, hopefully this will save other people some time: http://www.mail-archive.com/tomcat-dev@jakarta.apache.org/msg64410.html which says: And finally i find the solution,that is to remove all Naming-*.jar out from /%myapp_home%/WEB-INF/lib.I firmly think there's some disorder with tomcat classloader.In other words,ClassLoader may not check which class to be loader first and which to be loaded second and which have already be loaded! -Ken From: Ken Hall Sent: Thursday, December 16, 2004 3:41 PM To: '[EMAIL PROTECTED]' Subject: tomcat 5.5 and jndi context naming error Since downloading the new version of Tomcat 5.5.4, I have been experiencing problems with jndi resources within my web app. I am porting over from an existing server where that resource is working.

Tomcat 5 IIS 5 Integration
I am running Tomcat 5.0.25 and IIS 5.0 in tandem and am getting some strange configuration errors from the JK2 connector. It seems to lose connection between Tomcat and IIS and I can't seem to correct it. It appears to be random and happen at different times during the day. If I get 500 hits on the server, there will be about 5 cases, where Tomcat and IIS become disconnected and the session data is lost. Any help would be greatly appreciated. Here is from the Windows event viewer.
