I am not sure why I am experiencing this error. As I have the SWT properly installed and it was working fine before.

I reinstalled the F4 IDE and everything works fine now. Still unsure what I did to create this issue in the first place.

It sounds like it couldn't find the swt.jar usually located under %FAN_HOME%/lib/java/ext/<platform>/ - but as to why it would disappear from your environment I don't know.

I believe there is an Error with the IDE. It seems to always throw this Error if you don't use the embedded Library.

I'd be very surprised if that's the case - for I rarely use the embedded Library and have never suffered any problems.

What library are you using? How is it set up? And what system are you running? (mac / linux / win? 32 / 64? bit)

edit: deleted duplicate posting.

I added a win 64 SWT file and reloaded all my pods and that seemed to have fixed everything. Not quite sure what happened before, but everything seems to be working now.
