Hi everybody,

I’m evaluating the Java SDK 2.0.0 in order to use it in a software of mine.

I have a project and I was integrating the SDK inside my project. I ghace created a ScadaServer class where I have all the initialization stuff the same as in the Tutorial. I call this initialization at the beginning of my main, and when it comes to the call server.init(), I have the following exception trace:

Exception in thread “main” java.lang.RuntimeException: NodeManagerRoot

Any ideas?

Thank you very much in advance.

Hi David and welcome to the forums!

Apparently something goes wrong when initializing the information model. Does SampleConsoleServer work OK for you? Which parts have you copied into your own solution?

Yes, SampleConsoleServer works fine. I have copied your SampleConsoleServer.initialize function into a class of mine, and I call it at the very beginning of my program. In Netbeans I debug and when it goes through server.init() the exceotion arises.

Unfortunately the log doesn’t have enough information to say what the problem is. Is it possible for you to send us the relevant code to uajava-support@prosysopc.com so we can take a closer look?

Mmm, I think it is not necessary. I think this is a problem about packaging and executing.

I mean, I first opened your sample code with Netbeans, and compiled it. It created a jar file. Here I have two cases:

– If I embed every library inside this jar file to get a single, executable jar, I get a problem with th bouncycastle library. and JCE. I get an exception: JCE cannot authenticate the provider BC. You can read about this issue in : http://stackoverflow.com/quest…..pplication
– If I build the jar without libraries inside, I can execute the jar but I get the ModelException

So, I tried to execute the compiled classes like you did in SampleConsoleServer.bat, and everything went OK.

Is there any way to execute your library inside a jar file? or is there any documentation on this?

You cannot repackage it, since like you said JCE won’t accept it. You must use the original jar.

Can you check if the jar without the libraries inside contains Opc.Ua.NodeSet2.xml?

No, it is not. It is contained in your Prosys jar library only.

Could you modify the log.properties file to DEBUG and see what kind of log output you get? You can send it to us also.

It seems to be a problem with the dependencies. I write here how I am executing the project and the result. In build/clases there are the compiled classes in the folder com/soltec/scada/server/, and in the folder scada-server-scratch/lib there are all the libs from your SDK. And in dist there is the jar file generated from the compilation of the entire project.

Note that if I execute D:\scada-server-scratch>java -cp build\classes:lib\* com.soltec.scada.server.ScadaServer, everything works OK.

D:\scada-server-scratch\build\classes>java -cp ..\..\dist\Scada-server-scratch.jar;..\..\lib\* com.soltec.scada.server.ScadaServer

Can you try to isolate the problem (minimize what’s in your server)? The log is not informative in this case, since it does not show the cause of the NullPointerException. If you change the log level (row log4j.logger.com.prosysopc.ua=INFO -> DEBUG) you may get more information.

I have tried that, and the log is very long. If you need it complete, I can send you. But the first exception is:

Posting the fix in case someone else has the problem.

The line at start of SampleConsoleServer’s main method

PropertyConfigurator.configureAndWatch(SampleConsoleServer.class.getResource(“log.properties”).getFile(), 5000);

should be changed to call configure(…) method of PropertyConfigurator instead of the configureAndWatch method. This may should unrelated but it anyway fixed the problem.
