How to add a category while posting to wordpres?

[pumpadump]

Hi, i tried to post this question to stackoverflow but the recommended tag "wordpress-java" does not exist.

I want to use the wordpressj api client to post to wordpress via xmlrpc.
I'm using it like this:

    Wordpress wp =  new Wordpress(username, password, xmlRpcUrl);
    Post post = new Post();
    post.setPost_title("test");
    DateTime date = new DateTime(1990, 12, 1, 1, 1);
    post.setPost_date(date.toDate());
    post.setPost_status("pending");
    post.setPost_excerpt("test test");
    wp.newPost(post);

How can I add a category to this post?

You can find existing categories by:

List<Term> terms = WP.getTerms("category");

Each Term should have a name or slug to match for your required category. Find your term and do:

post.setTerm(Collections.singletonList(term));

to set one category. You can select multiple categories too.

BTW, I just noticed that creating a tag requires certain reputation in stackoverflow, which I don't have. I'll change the documentation until it matches my reputation on overestimation :)

Hi thanks for the explanation I did as you suggested but I have a different Problem now, if i run this code:

Wordpress wp =  new Wordpress(username, password, xmlRpcUrl);   
Post post = new Post();
post.setPost_title("test");
DateTime date = new DateTime(1990, 12, 1, 1, 1);
post.setPost_date(date.toDate());
post.setPost_status("pending");
post.setPost_excerpt("test test");
List<Term> terms = wp.getTerms("category");
terms.removeIf(term -> !term.getName().equals("test"));
post.setTerms(terms);
wp.newPost(post);

i get the following exception:

Exception in thread "main" net.bican.wordpress.exceptions.InsufficientRightsException 
at net.bican.wordpress.Wordpress.newPost(Wordpress.java:1251) 
at test.main(test.java:39)

I'm testing this with and Administrator account on a wordpress.com hosted site.

I was able to post with categories to this blog before by pasing this hashmap to a xmlrpc client:

HashMap hmContent = new HashMap();
hmContent.put("title", "test");
hmContent.put("description", "test test");
hmContent.put("post_status", "pending");
hmContent.put("categories", new String[]{"test"});

I'm using jwordpress version 0.6.2

Wordpress xml-rpc doc says it's one of the following:

1. If the user does not have the edit_posts cap for this post type.
2. If user does not have permission to create post of the specified post_status.
3. If post_author is different than the user's ID and the user does not have the edit_others_posts cap for this post type.
4. If sticky is passed and user does not have permission to make the post sticky, regardless if sticky is set to 0, 1, false or true.
5. If a taxonomy in terms or terms_names is not supported by this post type.
6. If terms or terms_names is set but user does not have assign_terms cap.
7. If an ambiguous term name is used in terms_names.

But I always notice inconsistencies in documentation and error codes of the xml-rpc part of wordpress, should debug.

I don't currently have immediate access to a wordpress installation. I'll get back in a day.

It's a "mysite".wordpress.com Administrator account according to wordpress the Administrator Role encompasses the following capabilities:
https://codex.wordpress.org/Roles_and_Capabilities#Administrator

So i guess 1+2 are not relevant. 3 also because there is only one user on this site. 4 also because i don't pass sticky. 5 i don’t know, if I post via wp-admin I can assign categories to a pending post so i guess it is also not relevant. 7 should be also not relevant because this is the only term named "test" on this blog.
Leaves us with 6 but why should and Administrator Role not have this capability?

This seems to be something I definitely overlooked, but hopefully fixed. I released a new version, please use 0.6.3. It should be visible on maven central. Meanwhile, you can use the jar file in the releases section.

Please let me know if it works for you.

I can confirm that it works now. Good job thank you!
