Hi Pete
I have now downloaded the Turbine snapshot of 12Sept. I am still having problems with
classes not being found. I get the ff exception on my browser: (not the whole
exception, just the top part):
***********************************
There has been an error! Please review the exception below for more information.
Get/Post Data:
screen = WebMacroSiteScreen
template = Error
The exception is:
java.lang.NoClassDefFoundError:
org/apache/turbine/services/cache/ObjectExpiredException

*****************************
My setup is as follows:
1. I am running tomcat
2. Turbine is in my context /lib directory, with all the other libs (WM, ECS, etc)
that turbine requires.
3. There are no other Turbine classes anywhere in my context path, tomcat classpath.
4. My application has classes in Web-Inf/classes and ONE OTHER DIRECTORY as well. This
other directory has been specified in Tomcat's classpath, and some of these classes
are actually being executed.
I now have no idea what is wrong, and this problem is driving me around the bend.
Any recommendations as to what I should try?
One other question: What is the order of the classpath which Tomcat searches - is it
webinf/classes, webinf/lib, and then the specified Tomcat classpath?
Regards
Chris

nope they are seperate classloaders. Or at least they
*should* be according to spec :P. They have to be seperate
because WEB-INF/classes is reloadable (and thus has to be
disposable) while WEB-INF/lib is meant to be static. So the
disposable CL has a parent CL that is responsible for
WEB_INF/lib

But it can matter to the run time :P. CL issues always
irritate me and it usually takes me ages to track them down
- one of the reasons I use WEB-INF/lib for more of my stuff
if I can help it.
Cheers,
Pete
