I have problem when use 'JNI'

Question

Hello every body,
I have an application language "C", which, I must make a wrapper java.
To do this using "JNI".
First I try to understand the functioning of JNI, I try it for the first example helloWorld.
all steps works well, and dynamic library was well create: libHelloWorld.so
The execution, it does'nt work
When I try to java Helloworld, here's what I see:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/java/jniexamples/HelloWorld/libHelloWorld.so: Can't load IA 32-bit .so on a IA 32-bit platform
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1751)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1676)
at java.lang.Runtime.loadLibrary0(Runtime.java:822)
at java.lang.System.loadLibrary(System.java:993)
at HelloWorld.<clinit>(HelloWorld.java:7)
Although I added the link to my library like this:
export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: / home / Install / java / jniexamples / HelloWorld
I dont understand where is the problem may be in the version I use of java, I use jdk-1.5.0-13?
Thank you in advance for your help
Regards
Daniel

Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/java/jniexamples/HelloWorld/libHelloWorld.so: Can't load IA 32-bit .so As a guess that would suggest that it found a file (thus the name is correct) but that the contents do not represent a shared library that the VM will load.
That is usually because the compile/link options are wrong for the target VM.
