After messing around with the parameters, I've fixed my case of "Error: null"
My solution : Replace the "not-working executable icon (.ico file)" in your JSmooth project by , for example, a very simple PNG file.
Question
Suppose I had a simple program called Main.class created from eclipse.
How would I create an .exe for that program? Does it have to be a .jar to work???
This is what I get when compiling:
Starting compilation
Scanning skeleton...
Loading Jar...
Adding Jar to Resources...
Adding Properties to Resources...
Loading icon...
Compilation failed!
(note I set the java version to 1.4)
The program itself is just a picture. There are no syntax errors at all. I had a little of bit of confusion in deciding what to put in the fields for every process in JSmooth. I only had one file to put anyway.
No correct solution

This is a common issue users come across. JSmooth seems very limited in the size and bitdepth of icons it supports. I don't know why it doesn't just toss it on as a resource like WinRun4J and let Windows pick the icon to use instead of preferring 32x32.
Try reducing the bit-depth and removing your larger icons to be just 16x16, 32x32 and maybe 48x48 and or 64x64 with only 4 or 8 bits of depth. Those are the settings that work for many people. Some use 32 bit PNGs but the docs say they are sampled down to 256 colors anyway.
I know this is an old question but I had the same problem and it was ultimately to do with my icon file.
No idea what was wrong with it but clearing the icon option fixed the problem.
