Sample client code using apache commons http client:-

private static void tableExtractionHOCR() {
		HttpClient client = new HttpClient();
		String url = "http://localhost:8080/dcma/rest/batchClass/tableExtractionHOCR";
		PostMethod mPost = new PostMethod(url);
		// adding file for sending
		File file1 = new File("C:\\sample\\sample.xml");
		File file2 = new File("C:\\sample\\US-Invoice_HOCR.xml");
		Part[] parts = new Part[2];
		try {
			parts[0] = new FilePart(file1.getName(), file1);
			parts[1] = new FilePart(file2.getName(), file2);
			MultipartRequestEntity entity = new MultipartRequestEntity(parts, mPost.getParams());
			mPost.setRequestEntity(entity);
			int statusCode = client.executeMethod(mPost);
			if (statusCode == 200) {
				System.out.println("Web service executed successfully.");
				String responseBody = mPost.getResponseBodyAsString();
				// Generating result as responseBody.
				System.out.println(statusCode + " *** " + responseBody);
			} else if (statusCode == 403) {
				System.out.println("Invalid username/password.");
			} else {
				System.out.println(mPost.getResponseBodyAsString());
			}
		} catch (FileNotFoundException e) {
			System.err.println("File not found for processing.");
		} catch (HttpException e) {
			e.printStackTrace();
