You can join the Virgo community by tweeting about #virgort, using the Virgo forum, subscribing to the virgo-dev mailing list, or using bugzilla. 

Meetings

There is a weekly, one hour call at 14:00 UTC on Tuesdays to discuss Virgo. See meetings for details.

Minutes

Contributing

Please read the Eclipse.org Terms of Use before making any contribution. Check out the flow chart in the Eclipse Legal Process poster. In particular, please make sure that you wrote 100% of the contribution and did not copy content from elsewhere or rely on the intellectual property of others.

Then attach your code as a patch (created using git diff) to a bugzilla bug so that the necessary due diligence and IP checks can be performed. In the bug you must confirm that you wrote 100% of the code you contributed (in particular that you didn't copy any of the code from elsewhere), that you have the right to contribute the code to Eclipse (e.g. your employer agrees or you wrote the code in your own time and your contract does not imply that the code is therefore your employer's), and that any new files contain the appropriate License header with yourself or your company, as appropriate, as the copyright owner and yourself as the initial contributor.

You should probably discuss large contributions (more than 250 lines of code and/or configuration) on the virgo-dev mailing list first so everyone knows what's going on.

Contributions should include unit tests whenever possible and integration tests where appropriate. This ensures that the contributed code is well structured and can be tested as well as preventing a technical debt of untested code.

Take Virgo for a spin

If you want to take the Virgo web server for a spin, first download it and unpack the downloaded archive to a directory, which we will refer to as $SERVER_HOME, ensuring there are no spaces in the path of the directory. On Windows unzip to a directory, which we will refer to as %SERVER_HOME%, again ensuring there are no spaces in the path of the directory. We recommend 7zip for unpacking on Windows as the built-in zip extraction utility sometimes fail to unpack reliably.

Then start the Virgo web server. On Unix, issue the following commands from a shell:

>cd $SERVER_HOME
>bin/startup.sh

On Windows, issue the following commands in a command prompt:

>cd %SERVER_HOME%
>bin\startup.bat

Virgo should issue event log messages like this:

You can then log in to the Virgo admin console (user "admin", password "springsource"). You should see the welcome panel of the admin console:
admin console welcome panel

You can then examine the features of the admin console. For example, you can explore the artifacts currently installed by clicking on the Artifacts pane and expanding some of the sections marked with '+' signs:

If you want to try deploying a bundle, drop it into the pickup directory:

org.eclipse.virgo.web-server/build-web-server/target/package-expanded/virgo-web-server-<version>/pickup

For example, if you download the trivial test application helloweb.war and drop it into the pickup directory, the following event log messages are displayed:

[2010-06-04 11:25:49.528] fs-watcher                   <DE0000I> Installing bundle 'helloweb' version '0.0.0'.

and you can then invoke the application or inspect it in the admin console:

Migration Notes

Migrating from dm Server 2.0.x to Virgo 2.1.0.x

The following changes in Virgo 2.1.0.x affect users migrating from dm Server 2.0.x:

Package Names

The Java package names of the code have been renamed from com.springsource or org.eclipse.

Some of these packages are more likely than others to be used by applications. For example, the following web configuration:

<context-param> 
    <param-name>contextClass</param-name>
    <param-value>com.springsource.server.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
</context-param> 

needs to be changed to:

<context-param> 
    <param-name>contextClass</param-name>
    <param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
</context-param> 

The main package changes are shown in the following table although very few of these are likely to impact applications. Users who have modified or extended dm Server are far more likely to be affected.


Package changes
dm Server 2.0.x Virgo 2.1.0.x
com.springsource.osgi.teststubs.* org.eclipse.virgo.teststubs.osgi.*
com.springsource.osgi.extensions.* org.eclipse.virgo.osgi.extensions.*
com.springsource.osgi.launcher.* org.eclipse.virgo.osgi.launcher.*
com.springsource.util.* org.eclipse.virgo.util.*
com.springsource.osgi.test.* org.eclipse.virgo.test.*
com.springsource.osgi.medic.* org.eclipse.virgo.medic.*
com.springsource.repository.* org.eclipse.virgo.repository.*
com.springsource.kernel.* org.eclipse.virgo.kernel.*
com.springsource.osgi.webcontainer.* org.eclipse.gemini.web.*
com.springsource.server.* org.eclipse.virgo.*

Shell

The kernel shell did not make it through the stringent Eclipse IP process and so Virgo extends the Equinox console instead.

The inline shell is no longer supported and the "-shell" switch on the startup script produces a warning.

The Equinox console is configured in the user region properties file via the osgi.console property with a default value of 2401.

The kernel properties shell.enabled and shell.port are no longer used and are ignored if specified. Remote access to the Equinox console is via telnet (whereas the kernel shell supported ssh).

Service Wrapper

The service wrapper did not make it through the stringent Eclipse IP process and so is no longer supported. Anyone needing this function will need to create their own service wrapper or take the one from dm Server 2.0.x and doctor it.

Migrating from the dm Server slices prototype to the Virgo snaps prototype

Even though the slices project was a prototype, a number of dm Server users found it very useful and asked for it to be made available on Virgo. It is currently being renamed to "snaps" and contributed to Virgo.

There will be a one-time hit for users to migrate from slices to snaps, largely because of the renaming.

Samples

The Petclinic and Spring Travel based samples are not provided with snaps as they derive from code whose authorship is not clear.

Package Names

The Java package names of the code have been renamed from com.springsource.osgi.slices.* or org.eclipse.virgo.snaps.*.

Class names

'Slice' is replaced by 'Snap' in class names.

Notable class name changes
dm Server slices Virgo snaps
com.springsource.osgi.slices.core.SliceHostFilter org.eclipse.virgo.snaps.core.SnapHostFilter
com.springsource.osgi.slices.Slices org.eclipse.virgo.snaps.Snaps
com.springsource.osgi.slices.SlicesTag org.eclipse.virgo.snaps.SnapsTag

Manifest headers

'Slice' is replaced by 'Snap' in manifest headers.

Manifest header changes
dm Server slices Virgo snaps
Slice-Host Snap-Host
Slice-ContextPath Snap-ContextPath

Bundle symbolic names

Bundle symbolic name changes
dm Server slices Virgo snaps
com.springsource.osgi.slices.api org.eclipse.virgo.snaps.api
com.springsource.osgi.slices.core org.eclipse.virgo.snaps.core

Plan names

Plan name changes
dm Server slices Virgo snaps
com.springsource.osgi.slices org.eclipse.virgo.snaps

Event log messages

The prefix SL is replaced by the prefix SN.
