Loading System libraries in MID server using Java Class

[Ebe]

Hi Folks,

I am trying to develop a POC in my personal ServiceNow instance and facing issue with MID server Java Call. So, to give an overview of what I am trying to do... 

-> I am trying to call Java class file from MID server and return the results in ServiceNow instance to build some reports and charts.

-> To do this, I have installed and configured my MID server. 

-> Deployed JAR file into ServiceNow instance (verified it in ~/extlib/ folder as well)

-> Start the MID Server and make sure it is up and running.

-> Call my java class by defining a "Queue" of JavascriptProbe. This is how my queue code looks like

<parameters>
<parameter name="script" value="var wsc = new Packages.com.client.TestClass(); wsc.searchByAttributes('Bobby','Jones','null','null','null');"/>
</parameters>

-> That particular java class in MID server has a line of code to load System library. (System.loadLibrary("G2"))

-> I have also verified that library is available in MID server "java.library.path" and also placed it under /usr/lib/ and /usr/lib/x86_64-linux-gnu/

After all these setup, when I executed the queue, no matter what I get below output all the time. 

Evaluation error: JavaScript evaluation error on:
var wsc = new Packages.com.client.TestClass(); wsc.searchByAttributes('Bobby','Jones','null','null','null');
Root cause of JavaScriptException: java.lang.UnsatisfiedLinkError

Please let me know how can I load libray in MID server from ServiceNow queue? Is there any alternate way to accomplish this? Any thoughts are greatly appreciated!

does any one have any insights on this? Any help is greatly appreciated!

I couldn't fix this issue since this involves accessing System Libraries of MID server in Service Now server. So, I have hosted API in MID server as Web Service and was able to access it outside without any issue.
