Yes, I had upgraded to Catalina in November, but it screwed up a lot of things, so reverted to Mojave. I thought that I restored everything back to what it was, but maybe not.

Thanks,

Hey Valerio,

That sheds some light… did you upgrade to Catalina or other OS changes? Many people got burned by Catalina moving directories under root to other locations messing up your class path. It’s very possible that your beans were arranged above your frank without you knowing… just by an OS upgrade.

In other words, it can find the magic locations for your frameworks anymore. “Configure build path” and see if things are read and need to be re-mapped. *Aaron Rosenzweig* / Chat 'n Bike <https://urldefense.proofpoint.com/v2/url?u=http-3A__www.chatnbike.com&d=DwMFaQ&c=slrrB7dE8n7gBJbeO0g-IQ&r=zZK0dca4HNf-XwnAN9ais1C3ncS0n2x39pF7yr-muHY&m=bRvHvGoIE939lB-I22_KxvKkW3ZMv0zUs8X5LpWJgJM&s=y3LkTL0h31RLWNB0rwny6icU-m6hISpKWjcsWFPJwcA&e=> *e:* aa...@chatnbike.com <mailto:aa...@chatnbike.com> *t:*  (301) 956-2319

Thanks for the reply.

I started that project about 15 years ago and the last time I fired it up successfully from Eclipse was in September. Then in December, without changing anything in the project, I could not do it anymore.

The JavaFoundation.framework in my path is /Library/WebObjects/Versions/WebObjects543/System/Library/Frameworks and NSCoding is definitely there.

I guess I'll have to try reinstalling Eclipse (sigh).

Sorry Valerio, 6 weeks is a long time indeed - you’ve been patient.

JNI has to do with Java making calls to a C library. That’s the “native method” part.

If it were me, I’d trash Eclipse and start over. I know that’s not what you want to hear but…

Hmm… thinking some more…

“NSCoding” lives inside the “JavaFoundation.framework” from Apple. Do you have that framework included in your project? Can you find it when you “configure build path” for your project? *Aaron Rosenzweig* / Chat 'n Bike <https://urldefense.proofpoint.com/v2/url?u=http-3A__www.chatnbike.com&d=DwMFaQ&c=slrrB7dE8n7gBJbeO0g-IQ&r=zZK0dca4HNf-XwnAN9ais1C3ncS0n2x39pF7yr-muHY&m=zNRTRtL2oKMEEiIf7TZw6uoVu7OjEorP2LTNGIVQQ8I&s=CJPoFIXrpAoGaeUPBMEl0iEevpJ6LnRfeG-05Aqm6VI&e=> *e:* aa...@chatnbike.com <mailto:aa...@chatnbike.com> *t:*  (301) 956-2319

6 Weeks ago I sent this message, but got no replies. Really nobody has any clue ?

btw: I get the same using a simple example app and trying from a clean workspace.

Hello all,

I have Eclipse Mars.2 running on a Mac with Mojave with JavaSE 1.8. I hadn't fired up my web app from Eclipse in a couple of months and today, without having any major changes to the O/S, when I tried I got:

    Error: A JNI error has occurred, please check your
    installation and try again
    Exception in thread "main" java.lang.NoClassDefFoundError:
    com/webobjects/foundation/NSCoding
        at java.lang.ClassLoader.findBootstrapClass(Native Method)
    .....

I find this message terribly vague. What should I be looking for ?

Thanks,
