I actually use JNA (Java Native Access) to access shared libraries (DLLs on Windows) instead of JNI. I added the jna.librabry.path to conf.bat as follows: rem # Path to jna.library.path set "JAVA_OPTS=%JAVA_OPTS% -Djna.library.path=C:\Software\VMWare\VSphere-4.1" I also added this code to my class:    static {                System.setProperty("jna.library.path", "C:\\Software\\VMWare\\VSphere-4.1");    } When I run the program in Jboss, I still got the following error: java.lang.UnsatisfiedLinkError: Unable to load library 'vix': The specified module could not be found. 2011-05-06 10:26:45,950 ERROR [STDERR] (WorkManager(2)-3)           at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:163) 2011-05-06 10:26:45,950 ERROR [STDERR] (WorkManager(2)-3)           at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:236) It seems that JBOSS could not find the DLLs resulting to UnsatisfiedLinkError. BTW, I tested this code in Eclispe and it ran fine! Certainly, Eclispe and JBOSS are two different environments. Also, I could not find the properties MBean in JMX-Console. Please let me know what additional info is needed for debug purpose. Any help from the community is greatly appreciated!

Should I have Jboss referenced this path? I could not locate MSJAVA.DLL. I did global search but yield nothing! Thanks for your prompt response.

But I think you're right. The load failed because it could not find the DLLs mneeded for vix.dll, which caused java.lang.UnsatisfiedLinkError.

If so, turn it on. If not, add logging code to it. Basically, you have to debug JNA and find out why it is not working correctly. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/604301#604301] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

The easiest way to find the pid is to look for the java.exe process in Task Manager. If there are multiple such processes, you will have to determine which one is running JBoss AS - usually has a large memory footprint, also it helps if you can view the command line. Task Mangere for Server 2003 doesn't showthe command line, if I recall correctly, so you might need to get Process Explorer for sysyinteranls also - it will provide the command line used to start java.exe - look fo the org.jboss.Main class. You might want to set a second filter that shows only file operations. Unfortunately, you can't set that as a single filter, but you can set the filter to remove events you don't care about. You don't need to filter out everything, just the really verbose stuff (that is, events that you don't care about but which happen quite often. Once the filtering is set up, run your app which attempts to load the dll. Then see what files are being accessed, and whether it was successful or not. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/605010#605010] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
