Error text file generates when creating an exe file using exe4j

My program is created using Netbeans and I need to make a .exe to make a setup file using innosetup, so I used exe4j to make the exe. This is what generates in a text file when all the steps are done.

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError:

Solution

Verify that org.netbeans.lib.awtextra.AbsoluteLayout is available in the classpath at runtime. You can locate AbsoluteLayout.jar in the NetBeans distribution, as shown below:

$ find . -name \*AbsoluteLayout\*
./Contents/Resources/NetBeans/java/modules/ext/AbsoluteLayout.jar
./Contents/Resources/NetBeans/java/sources/org/netbeans/lib/awtextra/AbsoluteLayout.java
