Unable to locate the application's 'man' class. The class 'org.jempeg.empeg.manager.Main' must be public and have a 'public state void main(String[])' method. (LAX).

I click on Details and get:

java.lang.ClassNotFoundException: org/jemepg/empeg/manager/Main
at java.lanc.Class.forName0(Native Method)
at java.lang.Class.forName(Unknown Source)
at com.zerog.lax.LAX.launch(Unknown Source)
at com.zerog.lax.LAX.main(Unknown Source)

I installed the full environment, and then made these chages:
1. renamed jemplode.jar to jemplode.jar.old in lib subdir (that's the 45 version)
2. move the jemplode.jar (54 version) into lib subdir (it's 1,963,869 bytes)
3. Commented out the old LAX.MAIN.CLASS setting in jEmplode.lax.
4. Added the following LAX.MAIN.CLASS setting in jEmplode.lax:
lax.main.class=org.jempeg.empeg.manager.Main
