Error in velocity and log4J
Solution 1
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?
Caused by: java.io.FileNotFoundException: velocity.log (Permission denied)
Solution 2
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);

Solution 3
It appears the process attempting to open the log file does not have permission to do so:
Caused by: java.io.FileNotFoundException: velocity.log (Permission denied)
Solution 4
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.
Solution 5
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 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):

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..
