How to get the results of a custom form-classification model with Java.

Question

I am trying to call out to a custom classification model in Azure form recognizer in Java with no success. Is there a Java sample available yet for the custom form classification preview, or an idea of when the API may be ready for full use? When I use the form-recognizer studio, I am pointed to the message below.
""" The code sample for Custom Classification Model operation will be coming soon. """ I have tried utilizing the API 3.0 documentation, but it appears to be more suited for custom document models and not the document classification models. Ideally, I was hoping there would be a similar approach to the code found here: https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/formrecognizer/azure-ai-formrecognizer/src/samples/java/com/azure/ai/formrecognizer/AnalyzeTaxW2.java Thanks in advance for the help.

Hello @Erik N
Thanks for reaching out to us. For Custom Classification Model, the JAVA SDK has not been released yet, so there is no working example for it. I will forward this feedback to product team and request the code sample to come soon. For API, could you please try if below code sample works or not? 1.Classify document with document classifier.

// // This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class JavaSample 
{
    public static void main(String[] args) 
    {
        HttpClient httpclient = HttpClients.createDefault();

        try
        {
            URIBuilder builder = new URIBuilder("https://westus.api.cognitive.microsoft.com/formrecognizer/documentClassifiers/{classifierId}:analyze?api-version=2023-02-28-preview");

            builder.setParameter("pages", "{string}");
            builder.setParameter("locale", "{string}");
            builder.setParameter("stringIndexType", "textElements");

            URI uri = builder.build();
            HttpPost request = new HttpPost(uri);
            request.setHeader("Content-Type", "application/json");
            request.setHeader("Ocp-Apim-Subscription-Key", "{subscription key}");


            // Request body
            StringEntity reqEntity = new StringEntity("{body}");
            request.setEntity(reqEntity);

            HttpResponse response = httpclient.execute(request);
            HttpEntity entity = response.getEntity();

            if (entity != null) 
            {
                System.out.println(EntityUtils.toString(entity));
            }
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

2.Gets the result of document classifier.

// // This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class JavaSample 
{
    public static void main(String[] args) 
    {
        HttpClient httpclient = HttpClients.createDefault();

        try
        {
            URIBuilder builder = new URIBuilder("https://westus.api.cognitive.microsoft.com/formrecognizer/documentClassifiers/{classifierId}/analyzeResults/{resultId}?api-version=2023-02-28-preview");


            URI uri = builder.build();
            HttpGet request = new HttpGet(uri);
            request.setHeader("Ocp-Apim-Subscription-Key", "{subscription key}");


            // Request body
            StringEntity reqEntity = new StringEntity("{body}");
            request.setEntity(reqEntity);

            HttpResponse response = httpclient.execute(request);
            HttpEntity entity = response.getEntity();

            if (entity != null) 
            {
                System.out.println(EntityUtils.toString(entity));
            }
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

I hope this helps. Regards, Yutong -Please kindly accept the answer if you feel helpful to support the community, thanks a lot.
