lpsolve - NoClassDefFoundError

[neelz040]

I am trying to run the ILP algorithm through RapidProM Extension 4.0.1 on a Mac OS 10.11.6 (El Capitan).

I reinstalled the RapidProM extension through the marketplace of the RapidMiner Studio.

It ran one day after initial installation. I did not do anything strange after that except clean my download folder and bin (??). Although I do not think this is the problem.

So, it works again ! I cannot tell you what I did because I don't know?? I am happy it works though :-)

[neelz040]

Maybe simple restart of my mac?

[abolt]

Hahaha well... not ideal, but if someone else has this same problem please let me know

[s-j-v-zelst]

it still appears, see issue #43 the ProM resource is not the same as the RapidProM resource, i.e. the lpsolve55j.jni file. It might be related to that

[s-j-v-zelst]

I've tested this on my macbook (from the source code) and i can not reproduce the error, lpsolve just works.

[abolt]

I just freshly installed rapidminer and rapidprom (from the marketplce) in my macbook pro and it just works...

[s-j-v-zelst]

It seems that for the other student that had the problem, restarting also did the trick.

[neelz040]

Restarting my notebook has so far always 'fixed' this issue. Just had it again

[benyaminsalimi]

I have the same problem, and I just restart my mac and problem is gone! I have no idea about this!

[RaphaelBijiaoui]

I stumble upon the problem and I reporduce it each time I run a "Conformance Checking" componant (MXML LegacyClassifier selected, the only option though). For my testing I started with the first tutorial provided with rapid prom and started eliminated component from finish to start until the error is no more encountered. Seems "Conformance Checking" is the one responsible. any idea ? (RapidMiner 9.0, RapidProm 4.0.0.1)

HI, I'm having this problem too. It's combined with a lot of other errors in the rapidprom extention:

Reinstalled everything, cleared caches, restarted everything. Kinda out of ideas. Hope you can help.
