There are a few Twitter
APIs for Java that allow you to integrate Twitter
functionality in a Java application. This is yet another
API, built using JAX-RS
and Jersey stack. I
started this effort earlier this year and kept delaying to
share because wanted to provide a more comprehensive API.
But I've delayed enough and releasing it as a
work-in-progress.
I'm happy to take contributions in order to evolve this API
and make it complete, useful, and robust. Drop a comment on the
blog if you are interested or ping me at @arungupta.
How do you get started ? Just add the following to your "pom.xml":
<dependency> <groupId>org.
glassfish.samples</groupId> <artifactId>twitter-api</artifactId> <version>1.0-SNAPSHOT</version></dependency>
The implementation of this API uses Jersey OAuth
Filters for authentication with Twitter and so the following
dependencies are required if any API that requires authentication,
which is pretty much all the APIs ;-)
<dependency>
<groupId>com.sun.jersey.contribs.jersey-oauth</groupId>
<artifactId>oauth-client</artifactId>
<version>${jersey.version}</version>
</dependency>
<dependency>
<groupId>com.sun.jersey.contribs.jersey-oauth</groupId>
<artifactId>oauth-signature</artifactId>
<version>${jersey.version}</version>
</dependency>
Once the dependencies are added to your project, inject Twitter
API in your Servlet (or any other Java EE component) as:
@Inject Twitter twitter;
Here is a simple non-secure invocation of the API to get you
started:
SearchResults result = twitter.search("
glassfish", SearchResults.class);for (SearchResultsTweet t : result.getResults()) { out.println(t.getText() + "<br/>");}
This code returns the tweets that matches the query "
glassfish".
The source code for the complete project can be downloaded
here. Download it, unzip, and mvn package will build the .war file. And then deploy it on
GlassFish or any other Java EE 6 compliant application server!
The source code for the API also acts as the javadocs and can be
checked out from
here.
A more detailed sample using security and several other API from
this library is coming soon!
