how to fix HTTP error fetching URL. Status=500 in

I am trying to crawl the user's ratings of cinema movies of imdb from the review page: (number of movies in my database is about 600,000). I used jsoup to parse pages as below: (sorry, I didn't write the whole code here since it is too long)

try {
  //connecting to mysql db
  ResultSet res = st
        .executeQuery("SELECT id, title, production_year " +
                "FROM title " +
                "WHERE kind_id =1 " +
                "LIMIT 0 , 100000");
  while (res.next()){
       .......
       .......
     String baseUrl = "http://www.imdb.com/search/title?release_date=" +
            ""+year+","+year+"&title="+movieName+"" +
            "&title_type=feature,short,documentary,unknown";
    Document doc = Jsoup.connect(baseUrl)
            .userAgent("Mozilla")
            .timeout(0).get();
      .....
      ..... 
//insert ratings into database
      ...

I tested it for the first 100, then first 500 and also for the first 2000 movies in my db and it worked well. But the problem is that when I tested for 100,000 movies I got this error:

org.jsoup.HttpStatusException: HTTP error fetching URL. Status=500,   URL=http://www.imdb.com/search/title?release_date=1899,1899&title='Columbia'%20Close%20to%20the%20Wind&title_type=feature,short,documentary,unknown

at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:178)
at org.jsoup.helper.HttpConnection.get(HttpConnection.java:167)
at imdb.main(imdb.java:47)

I searched a lot for this error and I found it is a server side error with 5xx error number.

Then I decided to set a condition that when connection fails, it tries 2 more times and then if still couldn't connect, does not stop and goes to the next url. since I am new to java I tried to search for similar questions and read these answers in stackoverflow:

Exceptions while I am extracting data from a Web site

Jsoup error handling when couldn't connect to website

Handling connection errors and JSoup

but, when I try with "Connection.Response" as they suggest, it tells me that "Connection.Response cannot be resolved to a type".

I appreciate if someone could help me, since I am just a newbie and I know it might be simple but I don't know how to fix it.

Well, I could fix the http error status 500 by just adding "ignoreHttpError(true)" as below:

org.jsoup.Connection con = Jsoup.connect(baseUrl).userAgent("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.21 (KHTML, like Gecko) Chrome/19.0.1042.0 Safari/535.21");
con.timeout(180000).ignoreHttpErrors(true).followRedirects(true);
Response resp = con.execute();
Document doc = null;

if (resp.statusCode() == 200) {
    doc = con.get();
......

hope it can help those have the same error.

however, after crawling review pages of 22907 movies (about 12 hours), I got another error:
"READ TIMED OUT".

I appreciate any suggestion to fix this error.

Upgrading my comments to an answer:

Connection.Response is org.jsoup.Connection.Response

To allow document instance only when there is a valid http code (200), break your call into 3 parts; Connection, Response, Document

Hence, your part of the code above gets modified to:

while (res.next()){
       .......
       .......
       String baseUrl = "http://www.imdb.com/search/title?release_date=" + ""
                + year + "," + year + "&title=" + movieName + ""
                + "&title_type=feature,short,documentary,unknown";
       Connection con = Jsoup.connect(baseUrl).userAgent("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.21 (KHTML, like Gecko) Chrome/19.0.1042.0 Safari/535.21").timeout(10000);
       Connection.Response resp = con.execute();
       Document doc = null;
        if (resp.statusCode() == 200) {
            doc = con.get();
                    ....
        }
