I built a webapp that works perfectly fine in my localhost (tomcat). But when I tried to deploy, velocity crashes in init(), leaving me with this strange stack trace here (sorry for the size):


ERROR [main] (VelocityConfigurator.java:62) - Error initializing Velocity!

Does anyone knows the workaround? Or at least understood the error? I've done some googling but no clues.. only this page facing the same problem but no solution..

I too had same Issue but I was able to resolve this overriding the default log file to customized log file. Just add this 3 lines of code in the method where you are calling evaluate Function.

Velocity.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,"org.apache.velocity.runtime.log.Log4JLogChute");

Velocity.setProperty("runtime.log.logsystem.log4j.logger","com.mindtree.igg.website.email.TemplateMergeUtilVelocityImpl");

VelocityContext velocityContext = new VelocityContext(parameters);

This is one way of solving it ie, without using property file.

I think this line has the answer. Looks like there is an issue creating the velocity.log file. What does your configuration file look like?

I have had exactly the same problem with my code and after hours of googling for that , I just decided to add some other Velocity libraries to my project. My project only had the apache-velocity jar file, then from here, I also added Velocity-Dep to my Maven project and Yesssssssssss! VICTORY!

I faced the same issue and have written a descriptive blog with the possible causes and solutions. Here is the link

Velocity tries to put the logfile in the directory Tomcat was started from, and I believe that is actually /.

You can force Velocity to log to Tomcat's standard log by adding these lines to your velocity.properties:

runtime.log.logsystem.class=org.apache.velocity.runtime.log.SimpleLog4JLogSystem
runtime.log.logsystem.log4j.category=velocity
runtime.log.logsystem.log4j.logger=velocity

The velocity.properties should go into /WEB-INF/velocity.properties but you can override that in you servlet definition in web.xml.

If you're initialising Velocity by properties and not the velocity.properties:

VelocityEngine engine = new VelocityEngine();

Properties props = new Properties();
props.put("runtime.log.logsystem.class", "org.apache.velocity.runtime.log.SimpleLog4JLogSystem");
props.put("runtime.log.logsystem.log4j.category", "velocity");
props.put("runtime.log.logsystem.log4j.logger", "velocity");

engine.init(props);

It appears the process attempting to open the log file does not have permission to do so:
