JNI Error with Java1.8.0_112 and Apache POI

Question

I have just installed Java1.8.0_112, both jdk and jre 64bit on my Windows 7 machine.

I am attempting to run one of my programs via a .bat file and am getting the following error:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/ss/use

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 7 more

I have uninstalled and reinstalled the jre and I have restarted my machine. I have made sure I am pointing to all the libraries needed.

What really baffles me is that this error is showing about the POI workbook, but I have all the apache libraries I need and their appropriate dependencies so I'm not sure why this is an issue. Like I said, runs like a charm in Netbeans on the jdk, but completely implodes when I run it on my desktop via .bat

The program runs just fine in the Netbeans8 environment, which is using the jdk of 1.8.0_112 and the JDK8 binary.

My .bat file is as follows, I've added line breaks for readability:

C:\jre1.8.0_112\bin\java -cp

Any help or guidance would be greatly appreciated, thank you!

Answer 1

Found the solution. The .bat file did not like me having libraries on mixed drives. Moving all the libraries to either my C: or the network S: drive solved the issue.

For whatever reason Netbeans was able to handle libraries in multiple locations but the .bat file does not.
