Currently, the only way to create a Petals POJO, is to create a new Java project, make it reference the required Petals libraries, implement the POJO, package it as a JAR and create a new SU project for POJO that will import this JAR.
The studio should provide a single wizard for this.
This wizard would ask the qualified name of the POJO, create a SU Java project, that would directly reference the required Petals libraries, and generate a skeleton for the POJO class.
The project export would, in addition to generating the SU, package the Java implementation as a JAR that would be part of the resulting SU archive.
