Fill-paragraph for javadoc in netrexx mode

[Arjan Bos]

Hello,

I'm in the process of writing a new major mode for NetRexx. NetRexx is a 
language that compiles straight into java and allows the use of all the 
nice features of java without the cumbersome syntax.[1]

One of the features NetRexx uses from java is the javadoc comment style. 
Could anyone enlighten me please how to use the feature from java-mode 
in my personal mode.
Do I need to copy the relevant elisp-code to my own mode? If so, which 
parts are the relevant ones?
Or is there a more elegant way to tap into that elisp-code?


Kind regards,
Arjan Bos
