    <p>I have a problem using google geocoding api. For example, with this url <a href="http://maps.google.com/maps/api/geocode/json?latlng=47.3195254,5.0430687&amp;sensor=true" rel="nofollow">http://maps.google.com/maps/api/geocode/json?latlng=47.3195254,5.0430687&amp;sensor=true</a>, I want to parse the json with jackson 2 to create the POJO.</p> <p>So my class is</p> <pre><code>public class GeocoderResult { @JsonProperty("results") private List&lt;GeocoderGoog&gt; geocoder; @JsonProperty("status") private String status; public List&lt;GeocoderGoog&gt; getGeocoder() { return geocoder; } public String getStatus() { return status; } } </code></pre> <p>To deserialize json, I use </p> <pre><code>HttpURLConnection connection = (HttpURLConnection) new URL(baseUrl).openConnection(); ObjectMapper mapper = new ObjectMapper(); // disable exceptions when there is unknown properties mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES); int statusCode = connection.getResponseCode(); Log.d(Constants.D_TAG, "Status : "+statusCode); if (statusCode == HttpURLConnection.HTTP_OK) { // 200 InputStream is = new BufferedInputStream(connection.getInputStream()); status = (Status) mapper.readValue(is, GeocoderResult.class); } </code></pre> <p>I have the following error :</p> <pre><code>09:38:42.737 Thread-24889 An exception occurred during request network execution :Unexpected close marker '}': expected ']' (for ROOT starting at [Source: java.io.BufferedInputStream@428a1840; line: 1, column: 0]) at [Source: java.io.BufferedInputStream@428a1840; line: 2, column: 14] com.fasterxml.jackson.core.JsonParseException: Unexpected close marker '}': expected ']' (for ROOT starting at [Source: java.io.BufferedInputStream@428a1840; line: 1, column: 0]) </code></pre> <p>I don't understand where is the problem ...</p> <p>ps : I use jackson-core, jackson-databind and jackson-annotations 2.1.4</p>

    1. COJSON you are getting is invalid -- some content is missing, most likely. Nothing to do with data-binding, exception comes straight from streaming parser.

    3. CONo. Read the exception message. Version incompatibilities give pretty distinct errors from class-loading. This indicates broken JSON input -- why that is the case I can not speculate. You can tackle that by first reading and buffering content, then giving it to parser -- and perhaps logging the input for trouble-shooting.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
