#4 click "Generate Source Codes" create NullPointerException
I use dbgen v1.2 on NT with JDK j2sdk1.4.1_01.
It works first time. But when i click on the button
"Generate Source Codes" the SCG-Wizard is not comming
up. The Project-Check runs with no errors.
What can i do? Please help.
Error after pressing the SCG button:
java.lang.NullPointerException
