Question

I'm trying to upload a post to my Blogger blog, yet I'm having an error. I'm using Eclipse and the libraries referesed are: google-oauth-java-client-1.17.0-rc and gdata-src.java-1.47.1.

Code:

import com.google.gdata.client.GoogleService;
import com.google.gdata.data.Entry;
import com.google.gdata.data.PlainTextConstruct;
import com.google.gdata.util.ServiceException;
import java.io.IOException;
import java.net.URL;

public class Blogger {
    public static void createPost(GoogleService myService) throws ServiceException, IOException {
         // Create the entry to insert
        Entry myEntry = new Entry();
        // POST Title
        myEntry.setTitle(new PlainTextConstruct("INDIA DEFEATED PAKISTAN "));
        // Post description
        myEntry.setContent(new PlainTextConstruct("INDIA Defeated pakistan in only 4 seconds . Hindustan Jindabad "));
        // Blogger URL
        URL postUrl = new URL("http://www.myblogspotsite.com/");
        myService.insert(postUrl, myEntry);
    }

    public static void main(String ar[]) throws ServiceException, IOException {
        //creating Google service required to access and update Blogger post
        GoogleService myService = new GoogleService("blogger", "exampleCo-exampleApp-1");
        myService.setUserCredentials("MY_GMAIL", "MY_PASSWORD");
        createPost(myService);
    }
}

Error:

Solution

The URL you are using to post, is not correct, the url should have the Blog Id,the format of the url is: 

http://www.blogger.com/feeds/BLOG_ID/posts/default

So in java, you can do this as follows:

        GoogleService myService = new GoogleService("blogger", "exampleCo-exampleApp-1");
        myService.setUserCredentials("EMAIL", "PWD");
        Entry myEntry = new Entry();
        myEntry.setTitle(new PlainTextConstruct("TITLE post update"));
        myEntry.setContent(new PlainTextConstruct("STATUS POST"));
        URL feedUrl = new URL("http://www.blogger.com/feeds/default/blogs");
        Feed resultFeed = myService.getFeed(feedUrl, Feed.class);
        String blog_name = "blog_name"; //the name of the blog where you want to post status
        String BLOG_ID = "";
        for (int i = 0; i < resultFeed.getEntries().size(); i++) {
            Entry entry = resultFeed.getEntries().get(i);
            if (entry.getTitle().getPlainText().equalsIgnoreCase(blog_name)) {
                String[] split = entry.getId().split("-");
                BLOG_ID = split[split.length - 1];
            }
            System.out.println("Posting to:" + " " + "Blog id: " + BLOG_ID + " " + "Blog name: " + blog_name);
        }
        URL postUrl = new URL("http://www.blogger.com/feeds/" + BLOG_ID + "/posts/default");
        Entry insert = myService.insert(postUrl, myEntry);
        System.out.println(insert.getHtmlLink().getHref());
