twitter4j error - connect timed out - twitter4j

Question

I am using the twitter4j code and I get connect timed out for making about 5 queries a day.
I am using twitter4j with a servlet and I get the error a lot with timeout.
What happens is that I run the code and the system provides the error when searching and hence the system stops and no more details are provided.
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
try {
Query query = new Query(searchTerm);
twitter4j.QueryResult result1;
do {
result1 = twitter.search(query);
List<Status> tweets = result1.getTweets();
int i=0;int maxint = 20;
for (Status tweet : tweets) {
i++;
if (i<maxint)
{
out.println("procvess");
xmlStr=xmlStr+"<tweet>";
String tweetText = tweet.getText();
tweetText=cleanStringData(tweetText );
HashtagEntity[] hashtags = tweet.getHashtagEntities();
URLEntity[] urls = tweet.getURLEntities();
Date createdDate = tweet.getCreatedAt();
User twitteruser = tweet.getUser();
long tweetId = tweet.getId();
long id1 = tweet.getInReplyToStatusId();
long id2 = tweet.getInReplyToUserId();
String userImageURL = twitteruser.getProfileImageURL();
String userProfileURL = "http://twitter.com/"+twitteruser.getScreenName();
String realname = twitteruser.getName();
String authorname = twitteruser.getScreenName();
Calendar cal = Calendar.getInstance();
cal.setTime(createdDate);
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
String tweetDateStr = String.valueOf(year)+"/"+String.valueOf(month)+"/"+String.valueOf(day);
int l=0;
xmlStr=xmlStr+"</tweet>";
}
// System.out.println("#" + tweet.getUser().getScreenName() + " - " + tweet.getText());
}
} while ((query = result1.nextQuery()) != null);
} catch (TwitterException te) {
te.printStackTrace();
out.println("Failed to search tweets: " + te.getMessage());
// return "<error>" + te.getMessage()+"</error>";
}
