Compilation Failure: byte[] cannot be converted to ByteString

[LibertyWalk]

I tried to "mvn clean install" this project to get the necessary files for integration in NIFI. However, I'm getting the following error message: C:\Users\libertywalk\Downloads\nifi-opcua-bundle_hasmap\nifi-opcua-bundle\nifi-opcua-service\src\main\java\com\hashmapinc\tempus\processors\StandardOPCUAService.java:[320,73] error: incompatible types: byte[] cannot be converted to ByteString

I'm not quite sure why this occurs. Here's my environment;

mvn -version output: Maven home: C:\Users\krennd\apache-maven-3.5.2-bin\apache-maven-3.5.2\bin.. Java version: 1.8.0_162, vendor: Oracle Corporation Java home: C:\Program Files (x86)\Java\jdk1.8.0_162\jre Default locale: de_DE, platform encoding: Cp1252 OS name: "windows 10", version: "10.0", arch: "x86", family: "windows" OPC Foundation Stack Version: 1.03.342.1-SNAPSHOT nifi-opcua-bundle branch: master

Hello

I have had the issue also, and do want a correct fix, but I have found a temporary workaround.

On checking the code, Line 320 is only used, if providing a certificate for the system (not generating one).

If you insert a comment "//"to line 320, the project will build and you can at least start to check your workflows.

// endpointDescription.setServerCertificate(myOwnCert.getEncoded());

I hope this helps

Hey Andrew, You are correct. We will be submitting a fix for this ASAP.

Hi Guys

I have added the service, but when I enable it, I get the following message:

StandardOPCUAService[id=e2d91445-0161-1000-0000-00001711dd07] Failed to invoke @OnEnabled method due to java.lang.ArrayIndexOutOfBoundsException: 0: 0

Any ideas?

[cherrera2001]

@AndrewMcCutcheon I will pull and build now...I will let you know.

[cherrera2001]

@AndrewMcCutcheon I found the issue and submitted a fix, would you mind pulling the branch noted in opcnifi-46 - Update code for latest UA Stack #47. Don't forget to build 1.03.342.1 of the UA stack and copy the jar into the deploy-local module.

If it works I will merge to master.

@LibertyWalk this should work for you as well.

Thanks!!

Hi Chris

Thanks for the quick response, but not good news I am afraid...

I have pulled the branch, and added the jar file, then when building the package using mvn clean install, I get the following error in compilation:

[cherrera2001]

Thats odd, can you ensure that line 45 on TestStandardOPCUAService.java has the following method signature:

server = new TestServer(45678, "user", "test");

The error that you are seeing is that some how your local repo did not get updated with the new test class...

[AndrewMcCutcheon]

Hi Chris

I have checked the file and it does indeed have that line., here are lines 44,45,46

    try {
        server = new TestServer(45678, "user", "test");
    } catch (Exception e) {

For reference, in order to avoid tainting the build I had already done, I created a new clone direc of nifiopc-46 in to a temporary folder

Regards

Andy

Hi Chris

Some breaking news...

I wnet back to the original master branch (where i had modified the pom.xml to the correct version of OPC UA Stack), and modified the StandardOPCUAService.java file changing line 320 from

endpointDescription.setServerCertificate(myOwnCert.getEncoded()); to endpointDescription.setServerCertificate(ByteString.valueOf(myOwnCert.getEncoded()));

I left the TestService unaltered, and did a mvn clean install

The NAR built, and I have imported it to my sanbox, and able to use GetNodeID (restricted to no security and no username /password).

I will do further checking on Monday and feed back the results of accessing this in sandbox, and also in PoC environments

Kind Regards

@AndrewMcCutcheon - I am facing a similar error - java.lang.ArrayIndexOutOfBoundsException: 0 Built opc-ua-stack-1.3.343.jar and nifi-opcua-bundle-nar-0.0.1-SNAPSHOT.nar file successfully. But there is some bug I believe, that gives me the error. Is there any temporary workaround?

[cherrera2001]

Hi All,

Sorry I have been AWOL for some time. Could you please give me an idea of what OPC server you are trying to connect to and I will come out with some workaround. Also, the OPC foundation did deprecate the Java SDK so I will need to plan on porting the controller service over to eclipse milo for future support.

@cherrera2001 - Thanks for your response. I am working on a B&R PLC which has its own OPC-UA server with Basic256 security policy, no username and password.

Any help would be appreciated!
