Class JSONException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

org.apache.wicket.ajax.json.JSONException

All Implemented Interfaces:

Serializable

public class JSONException
extends RuntimeException

Thrown to indicate a problem with the JSON API. Such problems include:

• Attempts to parse or construct malformed documents
• Use of null as a name
• Use of numeric types not available to JSON, such as NaNs or infinities.
• Lookups using an out of range index or nonexistent name
• Type mismatches on lookups

Although this is a checked exception, it is rarely recoverable. Most callers should simply wrap this exception in an unchecked exception and rethrow:

  public JSONArray toJSONObject() {
     try {
         JSONObject result = new JSONObject();
         ...
     } catch (JSONException e) {
         throw new RuntimeException(e);
     }
 }
