JSON Deserialization error in Java – Ebay API

I am trying to deserialize some JSON which I got from the eBay API but I am getting the error: com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_ARRAY token

The JSON that is returned has many levels to it. e.g.

{"searchResult":[{"@count":"100","item":[{"itemId":["281492499859"],"title":["Panasonic Lumix TZ20 Digital Camera in Good Condition"],... etc

This is for a property called itemId in CompletedListing (class defined below)

I am calling this method with the line:

CompletedListingContainer listing = mapper.readValue(new File("C:\resource\jsonresult.txt"), CompletedListingContainer.class);`

Here are my classes.

CompletedListingContainer

public class CompletedListingContainer {

  private ArrayList<CompletedListing> item;

  private ArrayList<SearchResult> searchResult;

  private List<String> paginationOutput;

  @JsonIgnore
  public List<String> getPaginationOutput() {
      return paginationOutput;
  }

  public ArrayList<SearchResult> getSearchResult() {
      return searchResult;
  }

  public ArrayList<CompletedListing> getItem() {
      return item;
  } 
}

SearchResult

public class SearchResult {

  @JsonProperty("@count")
  private String count;

  private ArrayList<CompletedListing> item;

  @JsonIgnore
  public String getCount() {
      return count;
  }

  public ArrayList<CompletedListing> getItem() {
      return item;
  }
}

CompletedListing

public class CompletedListing {

  @JsonProperty("itemId")
  private String itemId;

  private String title;

  @JsonProperty("itemId")
  public String getItemId() {
    return itemId;
  }

  @JsonProperty("title")
  public String getTitle() {
    return title;
  }
}

Any help would be greatly appreciated. Let me know if you need any more information.
