| <h1>JSON Interop Using JSNI</h1> |
| |
| <div class="intro"> |
| This example application demonstrates a simple approach to |
| interoperating with services that return their output in JSON format. |
| It uses GWT's JavaScript Native Interface (JSNI) to analyze a JSON |
| response and create Java-accessible objects. The JSON classes in this sample |
| are general-purpose and can be reused in other projects if you find |
| them useful. |
| |
| <p> |
| When you click the "Search" button below, you can browse the cached |
| results of a Yahoo JSON image search for "potato." The response is |
| parsed into Java objects which are used to populate a tree view below. |
| <ul> |
| <li>For more details on how the JSON response is parsed into a set |
| of Java objects, see the JSONParser class. |
| <li>The search URL used in this example was |
| <a href='http://api.search.yahoo.com/ImageSearchService/V1/imageSearch?appid=YahooDemo&query=potato&results=2&output=json'>http://api.search.yahoo.com/ImageSearchService/V1/imageSearch?appid=YahooDemo&query=potato&results=2&output=json</a>. |
