If you want to write mashups in Java these libraries might save you a lot of time. Just as with the
12 Ruby Resources we looked at last week, these resources can greatly simplify access to major APIs. Some are officially supported by the API providers themselves and others are independent, open source efforts.
- Facebook Java Client: Wraps the increasingly popular Facebook API. This library was recently updated in March.
- flickrj: A Java wrapper for the Flickr API.
- Amazon E-Commerce Applet: Java applet that demonstrates how to use every AWS 4.0 operation in REST and SOAP.
- Java Developer’s Guide for the Google Calendar API: Detailed examples for using the Java Client Library to work with the Google Calendar service including examples of adding events, updating events, deleting events and querying events. Note that Google also has a brief Java Developer’s Guide to Google Technologies.
- Google Base Java Client Library: “Google provides an extension to the Google data Java Client Library that helps connect to the Google Base feeds and interprets the result. This client library is by no means the only way of connecting to the Google Base API server. You can achieve the same result using an Atom parser, such as Rome, or a command-line tool, such as curl coupled with an XML parser.”
- Drest: Java API for popular web services. At the moment it supports Bloglines, Twitter and YouTube services.
- Yahoo! Mail: SOAP wrappers for a variety of languages including Java, PHP, Python and .NET.
The
Sun Web Developer Pack isn’t a sexy name, and having ‘Sun’ start it out often doesn’t help a technology…. but there is some good technology here.

eCirkit.com is a new social networking platform that has it's fair share of Ajax sprinkled in.
- On your profile page you can mouse over your user interests and a tooltip popup appears showing the full text of your interests, like favorite TV shows. You can then click the tooltip popup to go into edit mode, edit your data right in place, mouse out and your changes are sent to the server via Ajax.
- On your manager page, you can view your emails, then click an individual one to see full view in the main content window. From there you can reply and delete.
- You can use drag and drop to delete users from your contact list into a trash can. The contact is deleted from the backend server.
- You can use drag and drop to drag 2 of your contacts into the eCirkit connect panel, then type and introduction email. This will introduce the 2 users to each other, and they can then add each other to their contacts list.
The backend is a full Java J2EE web server. I use JSP pages and servlets in the web tier, EJBs in the middle business layer tier, and hibernate persistence layer for the database access.
Paco Avila and his team have announced
OpenKM, a document management / knowledge management system that looks like a desktop application.
OpenKM is based on:
- JBoss 4.0.3SP1 ( version basis for the development )
- Java J2EE ( JDK 1.5 )
- Jackrabbit
- GWT ( Google Web Toolkit - Ajax )
It is interesting to see a GWT application that looks like a YUI based component set.
Dojo is more than "an Ajax library". It is a set of JavaScript libraries and packaging system. It just so happens to have a remote binding API in there too.
Phobos has seen this and you can now
use Dojo on the server side when using the Phobos framework.
JAVASCRIPT:
-
-
response.status = 200;
-
response.contentType = "text/html";
-
writer = response.getWriter();
-
writer.println("<html><head><title>Dojo Sample</title></head><body>");
-
-
library.dojo.load();
-
dojo.require("dojo.widget.*");
-
-
writer.println("OK");
-
writer.println("</body></html>");
-
writer.flush();
-
We talked about
how Phobos could be a killer app under the nose of Sun in the past.
