Custom code generator, custom classes/interfaces names and new folders/files

Hi, I developed a custom code generator following the guidelines shared on the wiki. I managed to
define one that extends AbstractJavaJAXRSServerCodegen abstract class. I didn't figure out how to:

• define new folders and files inside them, in a programatic way (since I'm developing on an OSGi runtime, I was wondering if I could generate dynamically a ${component}.xml for each yaml file and ). I managed to create an OSGI-INF folder with writeOptional... method. Now I need to put as many .xml files as yaml files inside this folder.
• define my own policy for classes and interfaces names. My urgent need is to prefix interfaces with a I character to be compliant with code styling guidelines

Is it possibile ? I suppose I should work on my generator java class but I can't find any hint to do it. Also I didn't find exact references inside parent classes of my generator

Start with the custom generator Java class and its AbstractJavaJAXRSServerCodegen parent, then review the wiki guidance it follows. Trace the existing writeOptional... use for OSGI-INF and identify how generated paths and names are selected. Done means the generator can create one ${component}.xml per YAML file and apply the requested I-prefixed interface naming policy.
