    text
    copied!<p>I am using <code>spring android rest template</code> and trying to convert a JSON response into a java class as shown <a href="http://static.springsource.org/spring-android/docs/1.0.x/reference/html/rest-template.html#rest-template-examples" rel="noreferrer">here</a>.</p> <p>Here is my snippet trying to do the work:</p> <pre><code> RestTemplate restTemplate = new RestTemplate(); restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter()); //I have already tried to manually setting converters with no luck //List&lt;HttpMessageConverter&lt;?&gt;&gt; messageConverters = new ArrayList&lt;HttpMessageConverter&lt;?&gt;&gt;(); //messageConverters.add(new MappingJacksonHttpMessageConverter()); //messageConverters.add(new FormHttpMessageConverter()); //messageConverters.add(new StringHttpMessageConverter()); //restTemplate.setMessageConverters(messageConverters); Result result = restTemplate.getForObject(url, Result.class); </code></pre> <p>I think I have done everything required as it is told in the document:</p> <ul> <li>I have following jars in my classpath <ul> <li>jackson-all-1.7.6.jar</li> <li>spring-android-rest-template-1.0.0.M2.jar</li> </ul></li> <li>the <code>url</code> really returns a JSON object.</li> <li>My <code>Result</code> class is a POJO with all the required fields</li> </ul> <p>Basically having the <code>Jackson dependencies</code> in my classpath must be enough to get it work as it says:</p> <blockquote> <p>The MappingJacksonHttpMessageConverter is conditionally loaded when you create a new RestTemplate instance. If the Jackson dependencies are found in your classpath, the message converter will be automatically added and available for use in REST operations.</p> </blockquote> <p>So what I am missing here, what I am doing wrong?</p> <p>Thanks</p> <p>Full exception can be found here:</p> <pre><code>04-20 04:25:52.706: ERROR/AndroidRuntime(9638): FATAL EXCEPTION: main 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): java.lang.IllegalStateException: Could not execute method of the activity 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.view.View$1.onClick(View.java:2083) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.view.View.performClick(View.java:2421) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.view.View$PerformClick.run(View.java:8869) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.os.Handler.handleCallback(Handler.java:587) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.os.Handler.dispatchMessage(Handler.java:92) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.os.Looper.loop(Looper.java:143) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.app.ActivityThread.main(ActivityThread.java:5068) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at java.lang.reflect.Method.invokeNative(Native Method) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at java.lang.reflect.Method.invoke(Method.java:521) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at dalvik.system.NativeStart.main(Native Method) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): Caused by: java.lang.reflect.InvocationTargetException 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at xxx.SamplePageActivity.doRest(SamplePageActivity.java:83) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at java.lang.reflect.Method.invokeNative(Native Method) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at java.lang.reflect.Method.invoke(Method.java:521) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at android.view.View$1.onClick(View.java:2078) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): ... 11 more 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): Caused by: org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [[Lxxx.SamplePageActivity$Result;] and content type [application/json;charset=UTF-8] 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at org.springframework.web.client.HttpMessageConverterExtractor.extractData(HttpMessageConverterExtractor.java:77) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:449) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:404) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): at org.springframework.web.client.RestTemplate.getForObject(RestTemplate.java:202) 04-20 04:25:52.706: ERROR/AndroidRuntime(9638): ... 15 more </code></pre>
