问题:

I have this strange exception saying wrong ELF class but the wrapper is set correctly.

To read Belgiun ID card using this SDK from belgiun ID card issuers official site: http://eid.belgium.be/en/binaries/beid-sdk-3.5.3-ubuntu-9.10-i686-6193_tcm147-94066_tcm406-114986.tgz

回答1:

It doesn't work because you're using a 64-bit version of Java, and the SDK you're trying to use contains a 32-bit native library (libbeidlibJava_Wrapper.so.3.5.3). The 64-bit JRE cannot load 32-bit native libraries.

You'll need to use a 32-bit version of Java, or find a version of the SDK that has 64-bit native libraries.
