Use the Military Analyst/MOLE Java sample applications on Linux

Summary

When Java applications that depend on Defense Solutions MOLE/Military Analyst libraries are run on Linux with ArcGIS 10, the following error displays when invoking objects from these libraries:

"[java] AutomationException: 0x80040154 - Class not registered"

Instructions provided describe the workaround, which is to force the load of these libraries at runtime using a JNI call.

Procedure

1. Run 'make' from the $ARCGISENGINEHOME/bin folder. This builds 'libdefsolinitializer.so' and copies it to $ARCGISENGINEHOME/bin.
   
   If the ArcGIS Engine CPPAPI is not installed or a C build environment is not configured, a pre-built library file has been provided: libdefsolinitializer.so-prebuilt. Rename this file to libdefsolinitializer.so and manually copy it to $ARCGISENGINEHOME/bin. This pre-built binary has been tested only on a Redhat 4, 32-bit machine.

2. Insert the following code to the project or add the provided file DefSolInitializer.java to the project:
   
   package arcgissamples.defensesolutions;
   
   public class DefSolInitializer {
   /* Native method declaration */
   public native void initDefSol(); // needed to load COM types after 9.3.1
   
   /* Use static intializer */
   static {
   System.loadLibrary("defsolinitializer");
   }
   }
3. From the Java application requiring Defense Solution(MOLE/MA) libraries, add this code immediately after the call to AOInitialize().initialize:
   
   // Force load of Defense Solution Libraries:
   new arcgissamples.defensesolutions.DefSolInitializer().initDefSol();
