EBExtensions : Tomcat JVM Options

Question

Hi,  
I am new to Elastic Beanstalk and require help with the following issue.  
I have a Tomcat based web application which requires access to a native library.  
Running my application and specifying the -Djava.library.path=/path/to/my/lib in the JVM options field in the software configuration in the Elastic Beanstalk console works a treat.  
However, I wish to add this configuration to the .ebextensions file so that it gets applied automatically when additional instances are spun up. I have not been able to get this working using the configuration below :  
  
option_settings:  
  aws:elasticbeanstalk:container:tomcat:jvmoptions:  
    Xms: 756m  
    Xmx: 756m   
    XX:MaxPermSize: 128m  
    JVM Options: -Djava.library.path=/path/to/my/lib  
  
Thanks for your help.

Answer

I worked around the issue by setting the java.library.path as an environment property rather than via JVM Options.  
i.e.  
  aws:elasticbeanstalk:application:environment:  
    java.library.path: /path/to/my/lib

Answer

I had problems with this configuration as well. 
My mistake was that I wasn't enclosing the values in single quotes. 
The parameter value should be in single quotes: '-Duser.language=pt -Duser.region=BR'
My tomcat-setting.config ended up like this:

{ "option_settings": [ {
"namespace": "aws:elasticbeanstalk:container:tomcat:jvmoptions", "option_name": "JVM Options", "value": "'-Duser.language=pt -Duser.region=BR'" } ] }
