Twitter OSGI Viewtool

An osgi plugin for dotCMS that adds a viewtool for interacting with Twitter using Twitter4J.

Twitter4J Configuration

You need to create the following host variables and enter the values in your Default Host:

twitter4JConsumerKey - Text twitter4jConsumerSecret - Text twitter4jAccessToken - Text twitter4jAccessTokenSecret - Text twitter4jDebug - Boolean (Select or Radio with True/False)

For More information see the Twitter4J website: http://twitter4j.org/en/configuration.html

Installation

Make sure you have the Twitter4J Configuration setup before deploying the osgi jar
Navigate to the dotCMS Dynamic plugins page: "System" > "Dynamic Plugins"
Click on "Upload plugin" and select the .jar file located in the "build/jar/" folder
Click on "Exported Packages" and add the following to the bottom of the list

,com.dotmarketing.beans,
com.dotmarketing.business,
com.dotmarketing.util

Usage

You will want to have to Twitter4J JavaDoc handy: http://twitter4j.org/javadoc/index.html

The tool is mapped to the key $twitter and currently has the following methods implemented:

showUser - takes a twitter screen name or user id and returns a Twitter4J User Object: http://twitter4j.org/javadoc/twitter4j/User.html
getUserTimeline - takes a twitter screen name or userid, a page number, and a count and returns a List of Twitter4J Status Objects: http://twitter4j.org/javadoc/twitter4j/Status.html
getFollowersList - takes a twitter screen name or userid and returns the first 20 followers for that user. The list returned contains Twitter4J User Objects. Note that this method is not working so well currently due to the twitter apoi rate limits on fetching this data. If you plan on using this I would seriously reccomend using a block cache around the method
getUserListMembers - takes a twitter screen name or userid, and a list slug and returns up to 20 members of the list. The list returned contains Twitter4J Objects. Same note about twitter api rate limit applies.
getUserListStatuses - takes a twitter screen name or userid, a list slug, a page number, and a count and returns a list of Twitter4J Status Objects for the user's list.

If you would like to see more methods implemented please request them by submitting an issue to this github.

If a method is not working check your log file, you probably exceeded the twitter api rate limit. I would suggest wrapping any code that uses this in a block cache directive: http://dotcms.com/docs/latest/CacheHandlingWithTags
