Download an image with RestTemplate

andrea2453 — Wed, 05 Jun 2013 14:19:17 GMT

Hi,
is it possible to download an image from a Spring RESTful web service using RestTemplate?

Normally RestTemplate support this through java.awt.BufferedImage (See here in "Retrieving the photos"), but it's not available in Android.

How can I download an image with RestTemplate? And what's the Spring MVC counterpart?

Thank you.

No validating DocumentBuilder implementation available?

a2836572 — Mon, 03 Jun 2013 22:17:22 GMT

Hello,
I am Bernard a novice at Android spring.
I try to use a simple program that can print a "Hello world". in my android phone.
However, the part of spring code work well on PC, but fail on the android environment.

My code is so easy

Code:

        ApplicationContext context = 

            new FileSystemXmlApplicationContext("beans-config.xml");

         

        HelloBean hello = 

            (HelloBean) context.getBean("helloBean"); 

        System.out.println(hello.getHelloWord());

but, There are some Exception as below:

Code:

06-03 13:42:30.530: E/AndroidRuntime(3655): Caused by: javax.xml.parsers.ParserConfigurationException: No validating DocumentBuilder implementation available

06-03 13:42:30.530: E/AndroidRuntime(3655):     at org.apache.harmony.xml.parsers.DocumentBuilderFactoryImpl.newDocumentBuilder(DocumentBuilderFactoryImpl.java:61)

06-03 13:42:30.530: E/AndroidRuntime(3655):     at org.springframework.beans.factory.xml.DefaultDocumentLoader.createDocumentBuilder(DefaultDocumentLoader.java:130)

06-03 13:42:30.530: E/AndroidRuntime(3655):     at org.springframework.beans.factory.xml.DefaultDocumentLoader.loadDocument(DefaultDocumentLoader.java:74)

06-03 13:42:30.530: E/AndroidRuntime(3655):     at org.springframework.beans.factory.xml.XmlBeanDefinitionRead

Do it imply that the JAVAX in android are distinct from Java platform?
I use eclipse IDE and import the the android-spring jar
Should me use Mavon to build my project,? Then, everything will all right, isn't it?
Or,Could someone give me some advise?
Thank you

Upload Multipart JSON and File combination

CarlMeyer — Mon, 27 May 2013 08:27:28 GMT

Good day,

I am currently using RoboSpice with Spring Android framework to perform REST calls. I would like to perfrorm a multi-part form post, with a combination of JSON and files. I build up my REST template and add the necessary converters:

Code:

public RestTemplate createRestTemplate() { 

        RestTemplate restTemplate = new RestTemplate(); 

        

        restTemplate.getMessageConverters().add(new FormHttpMessageConverter());

        restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());

        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

        

        return restTemplate;

}

I then perform the post:

Code:

public boolean loadDataFromNetwork() throws IOException {

                String url = context.getString(R.string.service_url) + "Registration";

                

                HttpHeaders requestHeaders = new HttpHeaders();                                

                requestHeaders.setContentType(MediaType.MULTIPART_FORM_DATA); 

                

                MultiValueMap map = new LinkedMultiValueMap(); 

                map.add("request", registration); 

                for (FicaDocument document : registration.documents)

                        map.add(document.documentPath, new FileSystemResource(document.documentPath)); 

                HttpEntity> requestEntity = new HttpEntity>(map, requestHeaders);

                RestTemplate restTemplate = getRestTemplate(); 

                ResponseEntity responseEntity = restTemplate.postForEntity(url, requestEntity, String.class);                 

                

                return true;  

}

I now get the following error:

05-27 09:53:22.380: E//RequestProcessor.java:250(10601): 09:53:22.384 pool-2-thread-1 An exception occured during request network execution :Could not write request: no suitable HttpMessageConverter found for request type [com.flash.flashfica.types.FicaRegistration]

The registration type looks as follows (using Jackson here):

Code:

@JsonSerialize

@JsonIgnoreProperties(ignoreUnknown=true)

@SuppressWarnings("serial")

public class FicaRegistration implements Serializable {                                        

        @JsonProperty("FicaRegistrationId")

        public long ficaRegistrationId; 

        @JsonProperty("Name")

        public String name; 

        @JsonProperty("Surname")

        public String surname; 

        @JsonProperty("Documents")        

        public ArrayList documents;

}

I can confirm that the call works fine when I do not use multi-part and just post the registration object in isolation. The JSON in this instance is created perfectly. In fact, I use the same pattern all over my application.

Essentially, I need to perform a form post that combines JSON and Files in a single call.

Carl

Correct way to receive a binary file

deepwinter — Thu, 23 May 2013 05:48:18 GMT

I'm looking for an example of the correct way to receive a binary file with AndroidSpring (with RoboSpice). I put together the following, but I'm getting errors that indicate InputStream isn't the right parameterization. The error complains that there is no message converter to convert to InputStream from text/plain. The file is a binary sqlite database, so I'm also not clear why Spring thinks it is test/plain. What do I change to make this work? Thanks!!!!

class PlantListRequestListener implements RequestListener< InputStream > {
@Override
public void onRequestFailure( SpiceException e ) {

showProgress(false);

Observer.unhandledErrorToast("Error during request: " + e.getMessage(), DownloadProjectAssetsActivity.this);
e.printStackTrace();

}

@Override
public void onRequestSuccess( InputStream response ) {
FileOutputStream fos;
try {
fos = getBaseContext().openFileOutput( project.id+".plantlist.sqlite" , Context.MODE_PRIVATE);
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = response.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
response.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}

spiceManager.execute( Observer.observerAPI.getBinaryFileRequest(project. plantlist), null, DurationInMillis.NEVER, new PlantListRequestListener() );
