It has been a long time that I did not look in the update center and development wiki of Netbeans. And I have been very pleased to see that it is possible now to register OC4J 10g as a server in Netbeans 5.5 (and 6.0). To add it in your environment just do a :
- Tools > Update Center
- Select "Netbeans Update Center Beta"
- Select OC4J 10g
