hi guys:
i'm having trouble getting going with turbine (tdk-1.1a4 on linux) and
webmacro. i'm trying to get just the example template parsed and
returned. it seems to me that everthing is working except the call to
my class. i have edited and checked my
webapps/ProjectManagerWM/WEB-INF/conf/TurbineResources.properties files and
Webmacro.properties files but when i call my template with
http://frink:8080/ProjectManagerWM/servlet/Turbine/template/HelloWorldWM.wm;
i get the following html (snipped) --
<br>
<font color="red">
<!--
warning: attempt to write out undefined variable hello:
java.lang.NullPointerException
--> of the emergency broadcast station.
</font>
<br>
i do get the example nav top and nav bottom, so i can see that turbine
is handling the request...i have tried manually putting the class directory of my
webapp into my shell CLASSPATH, among other things, but still can't seem to
get it to call the class when i call the template.
any help or suggestions much appreciated.
