I'm trying to create a service with jersey using twitter4j but when
accessing the service I get the following error:
A message body writer for Java type, class java.util.ArrayList, and
MIME media type, application/json, was not found
seems like it does not know how to serialize/deserialize tweets.
my resource class looks like this:
@Produces("application/xml")
@Path("search")
public class TweetResource {
@Produces("application/json")
@GET
@Path("{phrase}")
public List<Tweet> searchPhrase(@PathParam("phrase") String keyword)
{
Twitter twitter = new TwitterFactory().getInstance();
List<Tweet> tweets = new ArrayList<Tweet>();
try {
Query q = new Query(keyword);
QueryResult result = twitter.search(q);
tweets = result.getTweets();
for (Tweet tweet : tweets) {
System.out.println(
" Geo:" +
tweet.getProfileImageUrl() +
" Loc:" + tweet.getLocation() +
"\t - " +
tweet.getCreatedAt() + "\t - "
+ tweet.getText());
}
} catch (TwitterException te) {
te.printStackTrace();
System.out.println("Failed to search tweets: " +
te.getMessage());
}
return tweets;
}
}
There is one concrete class, TweetJSONImpl but I don't know how to
use it
any help or suggestions?
