How to convert DOCX to PDF in JAVA with Aspose.Words REST API

Aspose.Words Cloud Product Family
1

Hi,
I am using Aspose.Words Cloud API for doc(x) conversion to PDF without using cloud storage.
The code snippet I am using is as -

import java.io.File;
import java.io.InputStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardCopyOption;
import com.aspose.words.api.WordsApi;
import com.aspose.words.model.ResponseMessage;

public class ConvertDocumentToFormatExample {

public static void main(String... argc) {
  try{

		WordsApi wordsApi = new WordsApi("MY_API_KEY",
				"MY_SID", false);
		String format = "pdf";
		String outPath = "";
		ResponseMessage apiResponse = wordsApi.PutConvertDocument(format, outPath, new File("path_to_doc_file"));
		if (apiResponse != null && apiResponse.getInputStream() != null) {
			InputStream responseStream = apiResponse.getInputStream();
			final Path destination = Paths.get("output.pdf");
			Files.copy(responseStream, destination, StandardCopyOption.REPLACE_EXISTING);
			System.out.println("conversion completed");
		}

	} catch (Exception e) {
	  e.printStackTrace();
  }
}

}

I am getting error as -
com.aspose.words.client.ApiException: {“Message”:“MIME multipart content is not supported by the operation.”}
at com.aspose.words.client.ApiInvoker.invokeAPI(ApiInvoker.java:262)
at com.aspose.words.api.WordsApi.PutConvertDocument(WordsApi.java:765)
at com.alphasense.docconverter.ConvertDocumentToFormatExample.main(ConvertDocumentToFormatExample.java:21)

Please let me know what is incorrect in my request

Please note since Aspose.Words Cloud 19.4 we have introduced API Version v4.0. It has a more simplified API structure and better memory management than older versions. Please find the updated Java code for DOCX to PDF conversion. Please let us know if you have any questions or suggestions.
