Pat, I am not talking from a great deal of experience, so others will confirm.
If you create a multi instance of Coldfusion there is a few things you need to take into consideration, I'll address your questions first. As far as class path order, I believe it is the order that is set in the jvm. As for the best location to place them, as long as it is in a class path then all will be fine. As for access via each instance, as long as you know if it will be accessible by all or just one then you can create them in the global resource, or instance resource. Each instance has its own jvm settings for this reason, so you can even use the resource to make datasources global or instance only. The best example I used this for was the mysql jdb connector, by placing this in the class path of the jrun jvm settings this becomes available to all instances and/or Context paths. The class path as long as it is in a jvm setting, can sit anywhere on the HD. Of course if these instances are clustered then, they are going to be global to each instance anyway.

We run a multi- instance enterprise installation and as far as i know there are number of ways to get a jar file into the classpath. 1. drop into WEB-INF\lib folder 2. drop into WEB-INF\cfusion\lib folder 3. edit the java.class.path property in the <JRUN_HOME>\bin\jvm.config file. 4. edit web.xml and change the cf.class.path variable 5. put the file into the <JRE_HOME>\lib\ext folder (usually only when theres a conflict with built in cf libraries ill do this) 6. Use the classloader method (but this means code changes to existing apps) Im thinking that i can set up on my server a 'C:\thirdy_party_apps\' and then put each JAR i need into this folder. This would mean i only have to put 1 entry into the cf.class.path setting in web.xml. Sometimes i have separate instances that use the same JAR, so id like an external folder if possible rather than copying files into each instance. Im just a little confused about the order that the server does the classpath lookups in I *think* it does it in this order cf.class.path (which includes the web-inf sub folders) java.class.path (defined in jvm.config) <JRE_HOME>\lib\ext Can someone confirm this ? I cant find much in the docs on it. Any thoughts on this setup ? Pat No virus found in this incoming message. Checked by AVG Free Edition.
