Java POS health check returns “java.lang.Unsatisfi

Question

I installed the Java pos adk (1.11.18) for Epson printer TMU230 connected through ethernet. I configured the printer by running setupPos.exe file. When I run the healthCheck.bat file it is showing this error in console.

I am using Windows Server 2003 and JDK 1.5.

Which library files are missing?

Answer 1

From a technical Java perspective: a DLL and a java library are either missing or expected at a different location.

From an application perspective: As you have an installation routine (manual) and some batch file shipped with the adk, I'm pretty sure that you should read the documentation again. I guess that you've missed a single step or changed installation paths so the batch file looks at wrong locations.

Answer 2

Short Answer: Check you java.library.path (System.out.println(System.getProperty("java.library.path"). Make sure there is jp_co_ epson_upos_firm_FirmNativeAccess.dll in the path.

Long Answer: If you are installing EPSON Java POS, open (Program Files)\EPSON\JavaPOS\SetupPOS\CheckHealth\checkhealth.bat. Check which jre is using to start CheckHealthTest.jar. Copy the jp_co_ epson_upos_firm_FirmNativeAccess.dll from jre\bin into Windows\System32\ or any path in java.library.path

Sample Program To Test

public class Test {

    public static void main(String[] args) {      
        System.out.println(System.getProperty("java.library.path"));
        System.loadLibrary("jp_co_epson_upos_firm_FirmNativeAccess");
    }
}
