Ok, friends. Trying to get JSPWiki set up on a new Amazon EC2 Unbuntu
16.04 instance I just stood up, and I'm having some trouble. Help?
I installed Tomcat8 using apt-get, I wound up with:
/etc/default/tomcat8
/etc/init.d/tomcat8
/etc/tomcat8
Catalina/localhost/{docs,examples,host-manager,manager}.xml
(These have docbase pointing to corresponding subdirs of
/usr/share.)
/usr/share/tomcat8
/var/lib/tomcat8, which has a webapps subdir.
It all seems to be working fine.
So, I downloaded jspwiki.war 2.10.2, renamed it to "wiki.war", and
copied it to /var/lib/tomcat8/webapps, where it promptly got unpacked.
Now, I can see it in my Tomcat app manager, but when I attempt to
start it, I get failures.
First, I got OutOfMemory errors.
I assume Tomcat's default -Xmx=128m is way too small, so I bumped it
up to 768m (I've only got a 1GB EC2 instance (t2.micro), so I think
768m is living dangerously, eh?).
Now I'm getting errors like
org.apache.catalina.core.ApplicationContext.log ERROR: Failed to create
a Wiki engine: JSPWiki: Unable to load and setup properties from
jspwiki.properties. Failed to start. Caused by: Failed to instantiate class
org.apache.wiki.PageManager; please check log files for better information.
(in localhost.2017-01-08.log)
and
java.io.FileNotFoundException: jspwiki.log (Permission denied)
(in catalina.out)
and
INFO [__DEFAULT__]
org.apache.catalina.loader.WebappClassLoaderBase.checkStateForResourceLoading
Illegal access: this web application instance has been stopped already.
Could not load [net/sf/ehcache/version.properties].
(in catalina.2017-01-08.log)
I grabbed jspwiki.properties with:
unzip jspwiki-war-2.10.2.jar ini/jspwiki.properties
and modified it as follows (renaming it jspwiki-custom.properties):

< jspwiki.baseURL=http://localhost:8080/JSPWiki/

> jspwiki.baseURL=http://web.how-hard-can-it-be.com/wiki/

885c885
< log4j.appender.FileLog.File = jspwiki.log
---
> log4j.appender.FileLog.File = /var/log/jspwiki/jspwiki.log
and tried deploying it to various places
({/var/lib,/usr/share}/tomcat8, /var/lib/tomcat8/webapps/wiki).
All to no avail.
What else can I try?
(I'm kind of a Rip van Winkle Java web app developer -- the last time
I touched this technology stack was more than ten years ago, and that
was on JBoss, all of which I've forgotten except the pain.)
Thanks.
John.
