Description

Description:
The full error stack on Linux follows:

 
Exception in thread "main" java.lang.UnsatisfiedLinkError: /tibco/tibco/tibic74/icapps/shared/native/lib/libicjni.so: /tibco/tibco/tibic74/icapps/shared/native/lib/libicjni.so: wrong ELF class:                ELFCLASS32 (Possible cause: architecture word width mismatch)

On Windows 7, the error stack looks like:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\TIBCO\InConcert740
PCGUI\icapps\shared\native\bin\icjni.dll: Can't load IA 32-bit .dll on a AMD 64-

Symptoms:
See above.

Cause:
InConcert is a 32-bit application which will run in 64-bit environments. The IcJava programs fail because they need to load native libraries and are also restricted to using 32-bit Java instead of the 64-bit version.

Resolution

Install and use a 32-bit Java release.
