How to publish a component using SDL Core Services in Java?

Question

I am trying to publish a component using core services in Java but on running the code, I am getting this error :-

Exception in thread "main" com.sdltridion.contentmanager.coreservice.ICoreServicePublishCoreServiceFaultFaultFaultMessage: Value cannot be null. Parameter name: publishInstruction.ResolveInstruction.

Here's my code

         ReadOptions readOptions = new ReadOptions();

    ArrayOfstring componentsArray=new ArrayOfstring();
    componentsArray.getString().add("tcm:1010-2312-16");


    ArrayOfstring publicationTarget=new ArrayOfstring();
    publicationTarget.getString().add("tcm:0-2-65537");

    PublishInstructionData publishInstructionData = new PublishInstructionData();
    ResolveInstructionData resolveInstructionData = new ResolveInstructionData();
    resolveInstructionData.setIncludeChildPublications(false);


    JAXBElement<ResolvePurpose> resolvePurpose =    new JAXBElement<ResolvePurpose>(new QName("http://www.sdltridion.com/ContentManager/R6","Purpose"), ResolvePurpose.class, ResolvePurpose.PUBLISH);
    resolveInstructionData.setPurpose(resolvePurpose);


    JAXBElement<ResolveInstructionData> jaxbElement =    new JAXBElement<ResolveInstructionData>(new QName("http://www.sdltridion.com/ContentManager/CoreService/2011","com.sdltridion.contentmanager.coreservice._2011.Publish"), ResolveInstructionData.class, resolveInstructionData);
    publishInstructionData.setResolveInstruction(jaxbElement);

     RenderInstructionData renderInstructionData = new RenderInstructionData();


      JAXBElement<RenderMode> renderMode =    new JAXBElement<RenderMode>(new QName("http://www.sdltridion.com/ContentManager/R6","RenderMode"), RenderMode.class, RenderMode.PUBLISH);
      renderInstructionData.setRenderMode(renderMode);

    JAXBElement<RenderInstructionData> renderInstruction =    new JAXBElement<RenderInstructionData>(new QName("http://www.sdltridion.com/ContentManager/CoreService/2011","com.sdltridion.contentmanager.coreservice._2011.Publish"), RenderInstructionData.class, renderInstructionData);



  publishInstructionData.setRenderInstruction(renderInstruction);




      ArrayOfPublishTransactionData ad= endpoint.publish(componentsArray, publishInstructionData, publicationTarget, PublishPriority.LOW, readOptions);

Answer 1

Looking at your implementation, publishinstructiondata has two main objects: ResolveInstructionData and RenderInstruction.

In your implementation, you have created object for ResolveInstructionData however you are missing RenderInstruction object. That could be reason the publishing is not working.

Answer 2

I think this is mainly a question on how to construct a proper SOAP request in general in Java (using JAXB?)

I recommend to enable WCF Tracing in the Core Service (there are comments in webservices/web.config on how to do that). This allows you to see the SOAP request sent to the Core Service to check what's in there and what's not.

Just adding this answer here since there was no accepted answer and might help people. The namespace URI and the service name used for the QName objects are incorrect for ResolvePurpose, ResolveInstruction and RenderInstruction.

To get the publish to work, I had to use the right namespace URIs and the service names. Something like this should work:

public class PublishService {   
    private static final QName RENDER_MODE_Q_NAME = 
                 new QName("http://www.sdltridion.com/ContentManager/R6", "RenderMode");
    private static final QName RESOLVE_PURPOSE_Q_NAME = 
                 new QName("http://www.sdltridion.com/ContentManager/R6", "ResolvePurpose");
    private static final QName RESOLVE_INSTRUCTION_DATA_Q_NAME = 
                 new QName("http://www.sdltridion.com/ContentManager/R6", "ResolveInstruction");
    private static final QName RENDER_INSTRUCTION_DATA_Q_NAME = 
                 new QName("http://www.sdltridion.com/ContentManager/R6", "RenderInstruction");

    public void publish() throws ICoreServiceGetApiVersionCoreServiceFaultFaultFaultMessage, 
                 ICoreServiceGetDefaultDataCoreServiceFaultFaultFaultMessage, 
                 ICoreServiceCreateCoreServiceFaultFaultFaultMessage,
                 ICoreServicePublishCoreServiceFaultFaultFaultMessage  {
        CoreService201603 coreService = new CoreService201603();
        ICoreService coreServiceClient = coreService.getBasicHttp();

        ArrayOfstring targetIdsArrString = new ArrayOfstring();
        targetIdsArrString.getString().add("tcm:0-20-65538");

        List<String> itemsToPublish = new ArrayList<String>();
        itemsToPublish.add("tcm:150-1365-512");

        ArrayOfstring itemsToPublishArrString = new ArrayOfstring();
        itemsToPublishArrString.getString().addAll(itemsToPublish);


        JAXBElement<RenderMode> renderModeJaxElement = 
                new JAXBElement<RenderMode>(RENDER_MODE_Q_NAME, RenderMode.class, RenderMode.PUBLISH);
        RenderInstructionData renderInstructionData = new RenderInstructionData();
        renderInstructionData.setRenderMode(renderModeJaxElement);

        JAXBElement<ResolvePurpose> resolvePurposeJaxElement = 
                new JAXBElement<ResolvePurpose>(RESOLVE_PURPOSE_Q_NAME, ResolvePurpose.class, ResolvePurpose.PUBLISH);
        ResolveInstructionData resolveInstructionData = new ResolveInstructionData();
        resolveInstructionData.setPurpose(resolvePurposeJaxElement);

        JAXBElement<RenderInstructionData> renderInstructionDataJaxElement = 
                new JAXBElement<RenderInstructionData>(RENDER_INSTRUCTION_DATA_Q_NAME, RenderInstructionData.class, renderInstructionData);
        JAXBElement<ResolveInstructionData> resolveInstructionDataJaxElement = 
                new JAXBElement<ResolveInstructionData>(RESOLVE_INSTRUCTION_DATA_Q_NAME, ResolveInstructionData.class, resolveInstructionData);

        PublishInstructionData publishInstructionData = new PublishInstructionData();
        publishInstructionData.setRenderInstruction(renderInstructionDataJaxElement);
        publishInstructionData.setResolveInstruction(resolveInstructionDataJaxElement);

        coreServiceClient.publish(itemsToPublishArrString, publishInstructionData, targetIdsArrString, PublishPriority.NORMAL, new ReadOptions());
    }
}

We can view how the SOAP body should look like and the namespaces and the service names to be used by loading up the WSDL in a tool like SoapUI.
