#Create a new Code Generation Configuration or edit an existing
##specify the existing output directory
##specify via the reveng.xml setup dialog the tables for reverse engineering
##select the exporters
##press ''Run'' or later ''Run->Hibernate Code Generation->&lt;Code Generation Configuration>''

===Debugging===
====Java Remote Debugging====
For example uweheuer:
# [[EDTLaptop1#Enable_Java_Debugging|start Wildfly for Debugginging]]
# select 'Debug Configuration' form Debug Menu and press 'Debug'
# after change to Debug View set breakpoints

====Java Applet Debugging====
There is a integrated applet viewer but setting breakpoints doesn't work, so it's better to use remote debugging. For example configuration 'uweheuer_applet_laptop'. Precondition is the configuration of the java runtime for applets:
* '''MS Windows:''' s. [[EONISLaptop#Java|Windows Java Configuration]] 
* '''Ubuntu:''' s. [[HomePC#Java_2|Ubuntu Java Configuration]]


====PHP Debugging====
s. http://www.eclipse.org/pdt/documents/XDebugGuideForPDT2.0.pdf
* set breapoints
* Run->Debug Configurations...-> e.g Local XT Sport Boeckmann -> Debug
