Claude Brisson commented on VELTOOLS-68:
----------------------------------------
I don't know exactly why, but this patch breaks velocity 1.4 compatibility:
Velocity 1.4 will search for Avalon and fail with:
java.lang.NoClassDefFoundError: org/apache/log/format/Formatter
at
org.apache.velocity.runtime.log.LogManager.createLogSystem(LogManager.java:162)
at
org.apache.velocity.runtime.RuntimeInstance.initializeLogger(RuntimeInstance.java:553)
at
org.apache.velocity.runtime.RuntimeInstance.init(RuntimeInstance.java:226)
at org.apache.velocity.app.VelocityEngine.init(VelocityEngine.java:80)
at
org.apache.velocity.tools.view.servlet.VelocityViewServlet.initVelocity(Unknown
Source)
at
org.apache.velocity.tools.view.servlet.VelocityViewServlet.init(Unknown Source)
...
And it will throw this exception even when velocity.properties contains:
# VelocityViewServlet uses the WebappLoader.
resource.loader = webapp
webapp.resource.loader.class =
org.apache.velocity.tools.view.servlet.WebappLoader
webapp.resource.loader.path = /
webapp.resource.loader.extension = vtl
Everything works fine with velocity 1.5-dev.

> Project: VelocityTools

> Affects Versions: 1.3
> Reporter: Henning Schmiedehausen
> Priority: Minor

> Attachments: velocity-tools.patch
>
>
> VelocityViewServlet configures the Velocity engine to use the ServletLogger
> (~line 323). Integration of the servlet into applications that use other
> logging systems (e.g. log4j / commons-logging) is very hard because of that.
> - VVS should honor the logging setttings in velocity.properties (e.g. for
> explicit jdk logging)
> - It should add the ServletLogger to the log engine search path and only use
> it if no other logger was found (log4j / avalon etc.)
> - The ServletLogger class implements the deprecated LogSystem. VelocityTools
> should provide a LogChute implementation of the SrevletLogger.
