Setting up Eclipse for Red5 Development

I've been playing with Red5, an open source alternative to Adobe's Flash

Communication Server. My Eclipse setup just died on me, so in the process of 

setting up eclipse for developing the Red5 server, I'll put up a quick tutorial on

using eclipse to work with Red5. Note that this is aimed more towards hacking

on Red5 itself than writing applications that use Red5, although the latter will

definitely benefit from starting with the setup I'll be doing.

Tools we will be installing:

- JDK SE 1.6 

- Eclipse SDK (Eclipse Classic)

- Spring IDE plugin for Spring development

- IvyDE for dependency management using the Ivy system.

- Subclipse for SVN management

We want to do some serious java development, so we're going to need the Java

Development Kit... Or, as it is now known, the Java Standard Edition. Download

the current JDK and install.

Next, we need Eclipse itself. I grabbed Eclipse Classic (Eclipse SDK) from Eclipse'

Downloads section. Another good alternative to start from is the Expert Java

build from EasyEclipse. Download the zip file and extract it to some directory. I

prefer C:\Program Files\eclipse for windows, or /home/njoubert/eclipse for

Ubuntu.

NOTE: If you want FlexBuilder as a plugin inside your eclipse install, you

should install flexbuilder NOW before doing anything else. There seems to be

some conflicts when FlexBuilder plugin gets installed after other 3rd party

plugins are present or something...

Open up Eclipse, and select whatever directory you want as your workspace. If you already have Red5 checked out somewhere, you can make the directory that

Red5 lives in as your workspace, or you can choose some other one, and we will

associate the already-checked-out code with the workspace you select a little

later.

Once Eclipse is running, we want to associate Eclipse with our shiny JDK that we

downloaded instead of sitting on top of the built-in JRE. Go to Window >

Preferences... and open Java > Installes JREs. It should show only the supplied

jre (jre1.6.0_01 for my Eclipse 3.3.0). Hit "Add...", then "Browse" for a JRE

home directory. (aka. "C:\Program Files\Java\jdk1.6.0_01"). Everything should

pop up. Hit OK, and make sure to select the new JDK in the list of Installed JREs.

Hit OK, and you're good to go.

Now we need to get IvyDE and the Spring IDE installed. The Spring IDE is

technically not necessary, and I tend to not use it in the areas of Red5 i'm

working on, but Red5 is built on top of Spring, so it's worth installing it and

removing later on if you think it is unnecessary. Eclipse plugins all follow the

same installation procedure, so i'll be a bit more detailed with the first plug-in,

and then roll with it for the rest.

Spring IDE 2.0 plays well with Eclipse Europa's Java Development edition, since

this Eclipse build comes with Mylyn, which Spring plugs into. Mylyn is a fancy task

manager that does all kinds of cool stuff, which i'm not going to go into now, butit worth looking at.

Spring IDE has an Eclipse update site, that Eclipse uses to install the plugin from.

go to Help > Software Updates > Find and Install.. in Eclipse, select "Search for

new features to install" and hit next. Current known sites pop up. Select "New

Remote Site..." and set the URL to http://springide.org/updatesite/ and name

to "Spring" (or whatever you want). Make sure there's a check next to it, and

hit "next". After contacting the site, Eclipse should show "Spring" as a feature to

install. Check it, and click Next. Accept the terms and select Finish. Click finish

to start the installation procedure. Eclipse will first download the necessary

utilities, then prompt you to install them. Restart Eclipse when prompted to.

Once Eclipse comes back, we follow the same procedure to add IvyDE to Eclipse.

There is a good tutorial on the Red5 wiki on installing IvyDE and using it with

Red5. For the moment, follow the previous procedure, with the update

site "http://www.jaya.free.fr/update".

Lastly we want to get Subversion compatibility for Eclipse, so we need Subclipse.

You can follow the same procedures as before, this time with the update

site "http://subclipse.tigris.org/update_1.2.x". When it prompts you for which

features to install, open up the Subclipse item and deselect Integrations. Some

of the integration plugins is not installed, so i just skip that part.

To get the current Red5 source from scratch, go to File > New > Project... and

choose SVN > Checkout projects from SVN. Select "Create a new repository

location" and use the URL "http://svn1.cvsdude.com/osflash/red5" in the next

section. Eclipse should resolve this and download a Table of Contents from which

you can select what you want to check out. Browse to java > server,

select "trunk" and go for it! This should check out and try to build Red5.

If you already have a copy on disk of Red5, I opted for a File > Import > File

System, and imported the root Red5 directory. Once this was in my workspace, I

About Me

Niels Joubert

I grew up in South Africa, where my

first contact with engineering and the

sciences came from my wonderful

parents. I started my web

development "career" through my

father's involvement with Silicon

Graphics, where I started off on

Cosmo Create, one of the first

WYSIWYG HTML editors, and I gave a

presentation on this at the

International Computer Fair at age

12. In the same year I became a

licensed amateur radio operator. I

grew up experimenting with APRS -

using GPS and Radio technology to

deploy cheap, effective position

feeds. My involvement with amateur

radio and the influence of my mentorHenry Chamberlain combined with my

love of computer science, which I

now bring to the University of 

California at Berkeley, where I am

studying EECS and Astrophysics. I

fancy myself a multidisciplinary

engineer with a love of the sciences.

I'm an active web developmer (using

RubyOnRails), and I won Berkeley's

Yahoo! Hack Day. I'm also doing

research in Berkeley's Astrophysicsdepartment, where I'm an

undergraduate image analyzer for

Alex Filippenko (US Prof. of the

Year). Last but not least, I invest a

lot of time in music, and my violin

and bass guitar is an integral part of 

my life.
