Epson JavaPOS ADK for linux 在与 eclipse 和 java 代码一起使用时出现错误

Question

I have an Epson TM-T88V printer and want to print a receipt with my own java code using eclipse. Have done the installation of javapos adk for Linux, set the /opt/EpsonJavaPos/bin to /root/.bash_profile, and of course java. Installed the tmt-cups driver as well and set up the printer using the PPD file. But after all these setups, I am getting the below error every time while trying to run my java code using eclipse. All the required javapos jars are present in jre/lib/ext folder and even set the native JNI library from /opt/EpsonJavaPos/bin to my java code using eclipse. Used SetupPOS to get the jpos.xml and dumped into the eclipse as well. Used check health test and getting the same below error as from eclipse while running my code-:

jpos.JposException: Failed to load the JNI.

I am stuck here for a long time and have no clue. Any help will be very appreciated.
