Assortment Planning on Solaris, Java environment variable question

I ran into a problem running a batch rule group:<N 2012Dec11 19:32:11.334> mace caught Exception:  Could not load library '/thirddisk/orpas/oretail/JDS/ap/rpas_app/rpas_13.2.3.37/rpas/applib/libaaijni.so' (Unix's errno 2; No such file or
 directory, dlerror: 'ld.so.1: mace: fatal: /usr/jdk/jdk1.6.0_26/jre/lib/sparc/client/libjvm.so: wrong ELF class: ELFCLASS32')
