NetBeans IDE is a full-featured integrated environment for Java application developers.
Java programmers require a fast and fully-featured Integrated Development Environment (IDE) with support for Java(TM) compliant applications for accelerating development across all major OS platforms.
NetBeans.org provides an open source, high performance, modular, extensible, multi-platform Java IDE to accelerate the development of Java applications, web services and mobile applications.
The NetBeans IDE 4.1, which was released in May 11, 2005, includes Java 2 Platform, Enterprise Edition (J2EE) development capabilities. This new release allows developers to not only develop applications in the web tier but also includes Enterprise JavaBeans (EJBs) and web service development capabilities.
NetBeans IDE 4.1 is a single platform with out-of-the-box development capabilities and support for enterprise (J2EE 1.4) applications and web services, mobile/wireless Java 2 Platform, Micro Edition (J2ME) applications and services and desktop Java 2 Platform, Standard Edition (J2SE) applications. The robust open source Java IDE, has everything that Java Software Developers need to develop cross-platform desktop, web and mobile applications straight out of the box.
When you download the NetBeans IDE, you get a modular, standards-based development environment with all the key functionality in one download, rather than a series of additional plug-ins. Write, compile, debug and deploy Java programs for the Solaris, Windows, Linux and Macintosh platforms.
Main features:
- New Navigator component facilitates browsing and navigating around classes.
- Browse and configure project classpath using the Libraries node in the Projects View.
- Use automatically generated Debug and Compile Single File actions for projects with existing build scripts.
- Set up projects with multiple source roots.
- Create a J2EE application, automatically add EJB?* and Web modules, then deploy the application.
- Deploy an EJB module as a stand-alone or packaged in a J2EE application. Or, create a Web module, generate calls to EJBs and deploy the Web module either as a stand-alone Web application or packaged in a J2EE application.
- Create Session Beans, Entity Beans and Message-Driven Beans. Entity Beans can be created using an existing database schema.
- Create, register and test Web Services.
- Visually configure your EJBs, Web Services and Web Components.
- Validate your applications using the J2EE Verifier.
- Use the integrated Java BluePrints Solution Catalog as a powerful learning resource.
- J2SE 5.0 "Tiger" Language Support - We support the new Java language constructs such as enums, generics, metadata annotations, autoboxing, static imports and others. These new constructs are supported when doing editing, building, refactoring, etc. of your applications. This support is available without any additional setup when running on J2SE 5.0.
- Project System based on Apache Ant - NetBeans 4.0 was the first IDE to base its projects system entirely on Apache Ant, allowing developers to easily share build scripts between teams and ensure that automated builds run the same as builds within the IDE. There is no vendor lock-in and no proprietary file formats.
- Refactoring technology which provides simplified code maintenance for developers.
- Visual enhancements to lay out MIDlets workflow; plus, design and code the GUI using a drag and drop feature (Available in NetBeans Mobility Pack).
- End-to-end support for enterprise applications with wizard support for creating Java? 2 Platform, Micro Edition (J2ME?) and J2EE applications. This updated support enables quick creation of J2ME client/server applications (Available in NetBeans Mobility Pack).

Openfire is a leading Open Source, cross-platform IM server based on the XMPP (Jabber) protocol.

Openfire server has great performance, is easy to setup and use, and delivers an innovative feature set.

Openfire is an enterprise instant messaging (EIM) server dual-licensed under the Open Source GPL and commercially. It uses the only widely adopted open protocol for instant messaging, XMPP (also called Jabber).

Openfire is incredibly easy to setup and adminster, but offers rock-solid security and performance.

Use Openfire in your organization as a more secure and feature-rich alternative to the consumer IM networks. Or, replace your existing EIM server with a more open, easier to use, and much less expensive solution.

Enterprise Grade

Openfire supports SSL/TLS encrypted connections out of the box as well as packet auditing to meet compliance requirements. Optionally tie Openfire into your organizations existing authentication system such as LDAP and then handle thousands of concurrent users on a single server.

Open Source and Open Protocol

Openfire is available under the Open Source GPL or a commercial license. It supports the open XMPP (Jabber) IM protocol and popular extensions. XMPP is supported by dozens of IM clients and allows for easy federation between IM servers. Openfire is among the most compliant XMPP servers available.

Cross-Platform

As a 100% Java application, Openfire supports Windows, Unix/Linux, and Mac OSX. The server can be deployed as a standalone application or service, or deployed in any J2EE compliant application server (Tomcat, Resin, etc) as a WAR (Web Application Archive).

Easy to Use

Get Openfire up and running within ten minutes. Then, administer the server using the web-based admin console.

Plugins

The server is easily extensible with a full plugin architecture. Visit the plugin library for a full list of available plugins.

Spark IM Client

Openfire works great with the cross-platform, feature-rich Spark IM client. Use the Spark Manager server plugin to manage the Spark clients on your server.

Server-Managed Contact Lists

Define groups of users in the server and then use the shared-group feature to automatically push those groups into users contact lists. This makes it very easy for people to start using the system and find the people they work with.

Cheyenne Secure Web Server (SWS) is a comprehensive enterprise solution for Apache server. Cheyenne Secure Web Server combines http firewall, JAVA, PHP, PERL and a domain control system with Apache HTTPD platform.

Courier-IMAP is a fast, scalable, enterprise IMAP server that uses Maildirs. Many E-mail service providers use Courier-IMAP to easy handle hundreds of thousands of mail accounts.
With the built-in IMAP and POP3 aggregation proxy in Courier-IMAP 4.0, the only practical limit to Couriers horizontal scalability is available LAN bandwidth. In proxy mode, a pool of Courier servers receive IMAP and POP3 connections from clients, wait for the clients to send a login request, look up the mail accounts server, and establish a proxy connection to the actual server that hosts the mail account.
Please note that this IMAP server does NOT handle traditional mailbox files (/var/spool/mail, and derivatives), it was written and optimized for the specific purpose of providing IMAP access to Maildirs.
"Maildir" is a directory-based mail storage format originally introduced in the Qmail mail server, and adopted as an alternative mail storage format by both Exim and Postfix. Courier-IMAP is popular on Qmail/Exim/Postfix sites that are configured to use maildirs. The primary advantage of maildirs is that multiple applications can access the same Maildir simultaneously without requiring any kind of locking whatsoever. Maildir is a faster and more efficient way to store mail. It works particularly well over NFS, which has a long history of locking-related woes.
This is the same IMAP server thats included in the Courier mail server, but configured as a standalone IMAP server that can be used with other mail servers - such as Qmail, Exim, or Postfix - that deliver to maildirs. A Courier/Postfix combination is very popular. If you already have Courier installed, you do not need to download this version. If you install this version, you must remove it if you later install the entire Courier server. Its possible to have both versions installed, but this will require a delicate juggling act that youll have to learn on your own.
Enhancements:
- A bug in quota calculation on 64-bit platforms has been fixed.
- The IMAP server will try to log the clients bandwidth usage if the server process gets killed by a signal.
- New messages created by the IMAP server will use the servers umask setting.
- Many compiler warnings, error messages, and manual page typos were fixed.
