From the error, it looks like the RPCRT4.dll DLL is causing an access violation. Is that DLL a JNI library?
Are there any other DLLs which the RPCRT4.dll library requires?

Java locates its direct JNI DLLs by searching the specified java.library.path But those JNI DLLs locate any required DLLs using the following search path. 1) working directory. 2) Windows directory. 3) Windows system directory. 4) PATH.

Is it possible that another DLL is not being located correctly? If so you might be able to resolve this by adding the following to your wrapper.conf:
set.PATH=lib;..\lib;%PATH%

You are running in Console mode, so the environment should be otherwise identical.

You can remove the Wrapper from the equation completely by doing the following.
1) Copy the full java command from the wrapper.log into a batch file.
2) Remove the -Dwrapper.key=NNN system property from the command line.
3) Run the batch file.
4) The JVM will run in a standalone mode without the Wrapper.exe, Can you still reproduce the problem?

Cheers,
Leif

I have set set.PATH=lib;..\lib;%PATH% and then run the service in console mode. Still it gives the problem.
Then i have -Dwrapper.key=NNN and run following command

"D:\Program Files\Java\jre1.6.0\bin\java.exe" -Djava.library.path="../lib;../../lib" -classpath "../lib/wrapper.jar;../../resources;../../lib;../../GlobasysLogger.jar" -Dwrapper.port=32000 -Dwrapper.jvm.port.min=31000 -Dwrapper.jvm.port.max=31999 -Dwrapper.debug="TRUE" -Dwrapper.pid=4820 -Dwrapper.version="3.3.0" -Dwrapper.native_library="wrapper" -Dwrapper.cpu.timeout="10" -Dwrapper.jvmid=1 org.tanukisoftware.wrapper.WrapperSimpleApp com.globasyslogger.startup.StartGLogger

Still it gives problem
Then i implemented wrapperListener in com.globasyslogger.startup.StartGLogger and tried it instead of org.tanukisoftware.wrapper.WrapperSimpleApp and set following properties

wrapper.java.mainclass=com.globasyslogger.startup.StartGLogger
and commented following line
#wrapper.app.parameter.1=com.globasyslogger.startup.StartGLogger

As a service it run but still have problem. Then i run the same using command prompt removing -Dwrapper.key=NNN

"D:\Program Files\Java\jre1.6.0\bin\java.exe" -Djava.library.path="../lib;../../lib" -classpath "../lib/wrapper.jar;../../resources;../../lib;../../GlobasysLogger.jar" -Dwrapper.port=32000 -Dwrapper.jvm.port.min=31000 -Dwrapper.jvm.port.max=31999 -Dwrapper.debug="TRUE" -Dwrapper.pid=4820 -Dwrapper.version="3.3.0" -Dwrapper.native_library="wrapper" -Dwrapper.cpu.timeout="10" -Dwrapper.jvmid=1 com.globasyslogger.startup.StartGLogger

And it works
I implemented WrapperListener because on service start i need to initialize some params and on stop i need to uninitialise (release) the resources. It is working in command prompt but not as a service

Please help,

I have a question, Why following command don't work

"D:\Program Files\Java\jre1.6.0\bin\java.exe" -Djava.library.path="C:\Program Files\GlobasysLogger\Java Service Wrapper\lib;C:\Program Files\Globasys Logger\lib" -classpath "C:\Program Files\Globasys Logger\Java Service Wrapper\lib\wrapper.jar;C:\Program Files\Globasys Logger\resources;C:\Program Files\Globasys Logger\lib;C:\Program Files\Globasys Logger\GlobasysLogger.jar;C:\Program Files\Globasys Logger\tools.jar" -Dwrapper.port=32000 -Dwrapper.jvm.port.min=31000 -Dwrapper.jvm.port.max=31999 -Dwrapper.debug="TRUE" -Dwrapper.pid=7576 -Dwrapper.version="3.3.0" -Dwrapper.native_library="wrapper" -Dwrapper.cpu.timeout="10" -Dwrapper.jvmid=1 org.tanukisoftware.wrapper.WrapperSimpleApp com.globasyslogger.startup.StartGLogger

And Following command works perfectly
"D:\Program Files\Java\jre1.6.0\bin\java.exe" -Djava.library.path="C:\Program Files\Globasys Logger\lib" -classpath "C:\Program Files\Globasys Logger\resources;C:\Program Files\Globasys Logger\lib;C:\Program Files\Globasys Logger\GlobasysLogger.jar;C:\Program Files\Globasys Logger\tools.jar" com.globasyslogger.startup.StartGLogger

What is the difference?
The error i get in the back end is

javafish.clients.opc.exception.ConnectivityException: The connection to the OPC Server has failed: localhost->OPCServer.WinCC
at javafish.clients.opc.JCustomOpc.connect(JCustomOpc.java:204)
at com.globasyslogger.logger.OPCMap.connectAndRegisterGroupsOfAllOpcs(OPCMap.java:90)
at com.globasyslogger.logger.SynchronousGroupReader.run(SynchronousGroupReader.java:147)
at java.lang.Thread.run(Unknown Source)

In first command if i replace org.tanukisoftware.wrapper.WrapperSimpleApp with com.globasyslogger.startup.StartGLogger it also works but then it restarts the JVM again and again

Everything is same (except in first case i use WrapperSimpleApp to launch and in second case i launched directly)then why is the error?

Please find the code for startLogger class below
public class StartGLogger {
private static Logger logger = Logger.getLogger(StartGLogger.class.getName());

public static void main\(String\[\] args\) \{ try \{ if \(\!LicenseObj.getLicenseObject\(\).isValidLicence\(\)\) \{ logger.error\("INVALID LICENSE"\); return; \} logger.error\("coinitilize JOPC"\); JOpc.coInitialize\(\); logger.error\("after coinitilize JOPC"\); \} catch \(CoInitializeException e\) \{ logger.error\(e\); \} try \{ Runtime.getRuntime\(\).addShutdownHook\(new Thread\(\) \{ public void run\(\) \{ endApp\(\); \} \}\); Thread t = new Thread\(new LoggerJob\(\)\); t.start\(\); logger.error\("main finished"\); \} catch \(Exception e\) \{ logger.error\(e\); \} \} public static void endApp\(\) \{ try \{ logger.error\("in shutdown hook"\); JOpc.coUninitialize\(\); \} catch \(Exception e\) \{ logger.error\(e\); \} \}

}

Thanks

The addition of the wrapper.jar to the classpath and the lib directory to the library path appear to be the only changes.
The WrapperSimpleApp class does nothing special re class loaders so I can think of nothing that might be caused by that.

What about the port? The Wrapper process has allocated port 32000 and the WrapperManager from java most likely allocated port 31000.
I was trying to figure out what the javafish.clients.opc.JCustomOpc class was? But didn't find much and am not sure what the jar does.

As an experiment, you can try changing the ports the wrapper uses like this:
wrapper.port=16123
wrapper.jvm.port=16124

Can't think of anything else that would be causing any problems for your application. If I knew what was happening in the source where that stack trace took place I might have more ideas.

Cheers,
Leif

I have tried changing the port. Still gives the same error.
I am also attaching the source files for OPC which is opensource and it needs JCustomOpc.dll which is placed in lib file.

If i replace
org.tanukisoftware.wrapper.WrapperSimpleApp
with
com.globasyslogger.startup.StartGLogger
The command run and don't throw this exception.
I am wondering what might be the problem?

Looking at the source for the JCustomOPC class, it looks like the native method connectServer is making a COMM call.

There have been other COM related problems in the past. See this page:
http://wrapper.tanukisoftware.org/doc/english/faq.html#4

Note the comment about the JAVA_HOME environment variable and javax.comm.properties file.

Try doing a Google search on javax.comm.properties

I do not have any experience personally with COMM so sorry if I am not directly helpful.

If you get it figured out or have more information, be sure to post back here.

Leif
