Tanuki uses the wrapper.conf file to define both JVM and application arguments. You need to set the wrapper.java.additional.N property (where N is the next number - for example, if there are already wrapper.java.additional.1 and wrapper.java.additional.2, you should set wrapper.java.additional.3). Here are the docs: http://wrapper.tanukisoftware.org/doc/english/properties.html By the way, the multiple exclamation points are really irritating.
