Hi All

I have a problem with my Tomcat 4.1.24 installation which I'm hoping =
someone may have an answer for. I have a little quartz scheduler running =
in Tomcat which I start with a servlet (previously started with a =
listener but switched to servlet in the hope it might fix things - both =
ways produced the same error).

When I start Tomcat up in my development mode which has the =
configuration shown below all works fine. When I start up in production =
mode however there seems to be problems with *some* Quartz scheduler =
threads picking up the initialContext???

I have a little utility for printing out the name tree and the output =
varies between quartz threads??

Here is an example of the output
