UnsatisfiedLinkError: wrong ELF class

[jelabarre59]

Trying to bring up a Remote Console for a Lenovo TS200 server.

I managed to finally get past the unsigned JAR file messages (hopefully not putting the rest of my system at risk in the process), but now I'm hitting a problem with OpenWebStart trying to run the JAR files.

eventually after a long LONG wait it starts to run the remote console application. At which point it fails with a "wrong ELF class" message.

I can't change the JAR files, the IMM is at the last firmware level made, so what's there is what I'm stuck with.

Running Fedora 38, java version java-1.8.0-openjdk-1.8.0.382.b05-2.fc38.x86_64

This sounds like the libavctKVMIO.so is a 32-bit library and you are currently running a 64-bit JVM.
OWS for Linux only supports 64-bit VMs. So if the 32/64 bit mismatch is the root of the problem your only option is to get a a 64-bit version of libavctKVMIO.so

Well, that's not going to happen. The firmware for this system was last updated in 2010 or 2011. Short of finding the source code hidden somewhere, and then a hack to call a local recompiled version rather than the version on the server's IMM. I guess I wasted my time hunting down the Virtual Media Key, since I can't make use of it (and I wanted to put this machine in another location where the circuit isn't already maxed out).
