Problem with Cache Velocity for template design

[nicolas muller <n....@nouvellemarque.com>]

Hello,

 I am using Roller 3.0 compiled from SVN with jdk 1.5, Tomcat 5.5.20 and
Mysql 4.x. I would like to desactivate the velocity cache because it is
impossible to
do web design with templates.

The parameter "reloadable='true'" is defined into conf / Catalina /
localhost / roller-3.0.xml for Context.

For the moment, I have the following configuration into velocity.properties.

# log invalid template references?

runtime.log.invalid.reference=false

# tell Velocity to use Log4J
runtime.log.logsystem.class=org.apache.velocity.runtime.log.SimpleLog4JLogSystem
runtime.log.logsystem.log4j.category=org.apache.velocity

# Override the default global library, set to blank to load no default
velocimacro.library = weblog.vm,feeds.vm,roller-custom.vm

# Change to false for deployment environments.
# Caching for the 'class' & 'webapp' ResourceLoaders must be false for
this to work
velocimacro.library.autoreload=true

# Allow Velocimacros to be defined in regular templates
velocimacro.permissions.allow.inline=true

# Allow template authors to define macros in any template
velocimacro.permissions.allow.inline.local.scope=false

# set encoding/charset to UTF-8
input.encoding=UTF-8
output.encoding=UTF-8
default.contentType=text/html; charset=utf-8

I Don't understand why the cache is not desactivated. For each
modification, I must restart Tomcat :-(

 Thanks Much. Best regards, Nicolas

Yes, that is painful. You might want to try the Velocity mailing list
if you have not already done so.
