Method Detail

newInstance

public static NodeLauncher newInstance()

Returns a new launcher instance.

Returns:

a new launcher instance

createNodeFromURL

public <T> T createNodeFromURL(java.lang.String configurationURL)
                    throws LauncherException

Creates a new SCA node from the configuration URL

Parameters:

configurationURL - the URL of the node configuration which is the ATOM feed that contains the URI of the composite and a collection of URLs for the contributions

Returns:

a new SCA node.

Throws:

LauncherException

createNode

public <T> T createNode(java.lang.String compositeURI,
                        Contribution... contributions)
             throws LauncherException

Creates a new SCA OSGi Node.

Parameters:

compositeURI - the URI of the composite to use

contributions - the URI of the contributions that provides the composites and related artifacts. If the list is empty, then we will use the thread context classloader to discover the contribution on the classpath

Returns:

a new SCA node.

Throws:

LauncherException

createNode

public <T> T createNode(java.lang.String compositeURI,
                        java.lang.String compositeContent,
                        Contribution... contributions)
             throws LauncherException

Creates a new SCA OSGi Node.

Parameters:

compositeURI - the URI of the composite to use

compositeContent - the XML content of the composite to use

contributions - the URI of the contributions that provides the composites and related artifacts

Returns:

a new SCA node.

Throws:

LauncherException

createNodeFromClassLoader

public <T> T createNodeFromClassLoader(java.lang.String compositeURI,
                                       java.lang.ClassLoader classLoader)
                            throws LauncherException

Create a SCA node based on the discovery of the contribution on the classpath for the given classloader. This method should be treated a convenient shortcut with the following assumptions:

• This is a standalone application and there is a deployable composite file on the classpath.
• There is only one contribution which contains the deployable composite file physically in its packaging hierarchy.

Parameters:

compositeURI - The URI of the composite file relative to the root of the enclosing contribution

classLoader - The ClassLoader used to load the composite file as a resource. If the value is null, then thread context classloader will be used

Returns:

A newly created SCA node

Throws:

LauncherException

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception
