Usage for MetaWeblog API for deletePost.

Hi -

I am trying to delete a post using MetaWeblog API. My code is as folows:

        Boolean result = (Boolean) client.execute("metaWeblog.deletePost",
            new Object[] {appKey, postId, username, password, Boolean.TRUE});

When I run this code I always get back false and the post is not deleted from the roller database.

I also have the following settings in my roller-custom.properties file:

webservices.atomprotocol.enabled=true
webservices.adminprotocol.enabled=true

What am I doing wrong? How come I cannot delete the post?

Any pointers will be welcome.

Manu

Have you tried adding
log4j.category.org.apache.roller.weblogger.webservices.xmlrpc=DEBUG

to your roller-custom.properties file?  That should give you some more information on what's going on.

Have you tried adding or editing posts?  And does that work?

Do you have preferences->settings->Enable weblog client support selected?  I believe admin and atom protocols are separate from xmlrpc, but I wouldn't bet my life on it or anything.

Thanks for your response. The answer to all your questions is 'Yes' except for the logging. I turned on logging on now.

This time in addition to logging I directly queried the database. Previously I was  refreshing the blog page and wrongly concluding that the post was not being deleted. In reality the weblogentry record is deleted the first time I try my code but a java exception is being thrown during rollers attempt to flush the cache. On each subsequent call I was getting false because that is what the code does when no weblogentry record is found.

So there seems to be two issues:

        1. Why is roller not rolling back the database transaction on exception (could be an issue with my test mysql implementation)?
        2. Why is roller not able to flush the cache?

See extract from roller.log below:

Subject: RE: Usage for MetaWeblog API for deletePost.



Have you tried adding
log4j.category.org.apache.roller.weblogger.webservices.xmlrpc=DEBUG

to your roller-custom.properties file?  That should give you some more information on what's going on.

Have you tried adding or editing posts?  And does that work?

Do you have preferences->settings->Enable weblog client support selected?  I believe admin and atom protocols are separate from xmlrpc, but I wouldn't bet my life on it or anything.

I don't know, I'm not too familiar with the code, but that looks like a bug to me.

I think Atom is better supported by roller, so you might want to try that instead of metaweblog...

Maybe someone else has a good idea what to do.

In reality the weblogentry record is deleted the first time I try my code but a java exception is being thrown during rollers attempt to flush the cache. On each subsequent call I was getting false because that is what the code does when no weblogentry record is found.
