Class ScatteredArchive

java.lang.Object

org.glassfish.embeddable.archive.ScatteredArchive

public class ScatteredArchive
extends Object

Abstraction for a Scattered Java EE module (parts disseminated in various directories).

Usage example :

         GlassFish glassfish = GlassFishRuntime.bootstrap().newGlassFish();
         glassfish.start();
 
         // Create a scattered web application.
         ScatteredArchive archive = new ScatteredArchive("testapp", ScatteredArchive.Type.WAR);
         // target/classes directory contains my complied servlets
         archive.addClassPath(new File("target", "classes"));
         // resources/sun-web.xml is my WEB-INF/sun-web.xml
         archive.addMetadata(new File("resources", "sun-web.xml"));
         // resources/MyLogFactory is my META-INF/services/org.apache.commons.logging.LogFactory
         archive.addMetadata(new File("resources", "MyLogFactory"),
                 "META-INF/services/org.apache.commons.logging.LogFactory");
 
         Deployer deployer = glassfish.getDeployer();
         // Deploy my scattered web application
         deployer.deploy(archive.toURI());

Constructor Detail

ScatteredArchive

public ScatteredArchive(String name,
                ScatteredArchive.Type type)

Construct a new empty scattered archive.

Parameters:

name - name of the archive.

type - type of the archive

Throws:

NullPointerException - if name or type is null

ScatteredArchive

public ScatteredArchive(String name,
                ScatteredArchive.Type type,
                File rootDirectory)
                 throws IOException

Construct a new scattered archive with all the contents from the rootDirectory.

By default, a scattered archive is not different from any other archive where all the files are located under a top level directory (rootDirectory).

For example, In case of a WAR type archive, the rootDirectory should look like this:

      rootDirectory/WEB-INF/classes/org/myorg/FooServlet.class
      rootDirectory/WEB-INF/classes/org/myorg/Bar.class
      rootDirectory/WEB-INF/web.xml
      rootDirectory/WEB-INF/lib/myjar.jar
      rootDirectory/index.jsp
      rootDirectory/theme.css
      rootDirectory/helper.js
 

Some files can then be scattered in different locations and be specified through the appropriate add methods of this class.

Parameters:

name - name of the archive.

type - type of the archive

rootDirectory - root directory.

Throws:

NullPointerException - if name, type or rootDirectory is null.

IOException - if rootDirectory does not exist.

IllegalArgumentException - if rootDirectory is not a directory.

Method Detail

addClassPath

public void addClassPath(File classpath)
                  throws IOException

Add a directory or a JAR file to this scattered archive.

The classpath that is added is considered as a plain Java CLASSPATH.

Case 1 : classpath is a directory:

Let us say there is TEMP/abc directory, which has following contents:

      TEMP/abc/org/myorg/a/A.class
      TEMP/abc/org/myorg/b/B.class
      TEMP/abc/com/xyz/c/C.class
      TEMP/abc/LocalStrings.properties
      TEMP/abc/image/1.png
 

then addClassPath(new File("TEMP", "abc") will make:

(a) The following classes available in the deployed scattered archive application:

          org.myorg.a.A
          org.myorg.b.B
          com.xyz.c.C
 

(b) LocalStrings.properties available in the deployed scattered archive application. So, the deployed application can do ResourceBundle.getBundle("LocalStrings");

(c) image/1.png available in the deployed scattered archive application. So, the deployed application can load the image file via getClass().getClassLoader().getResource("image/1.png");

If there is any other type of file under TEMP/abc then it will also be available in the deployed scattered archive application's classloader.

Case 2: classpath is a JAR file

Let us say there is TEMP/xyz.jar, then addClassPath(new File("TEMP", "xyz.jar")) will make all the classes and any random files inside TEMP/xyz.jar available in the deployed scattered archive application.

Parameters:

classpath - A directory or a JAR file.

Throws:

NullPointerException - if classpath is null

IOException - if the classpath is not found.

addMetadata

public void addMetadata(File metadata)
                 throws IOException

Add a new metadata to this scattered archive.

The addMetadata(metadata) method has the same effect as:

      addMetadata(metadata, null)
 

Follows the same semantics as addMetadata(File, String) method.

Throws:

IOException

addMetadata

public void addMetadata(File metadata,
               String name)
                 throws IOException

Add a new metadata to this scattered archive.

A metadata is identified by its name (e.g., META-INF/ejb.xml).

If the specified name is null, then the metadata is considered as a deployment descriptor metadata and the name is computed as:

      "WEB-INF/" + metadata.getName() for WAR type archive.
      "META-INF/" + metadata.getName() for other type of archive.
 

If the scattered archive already contains the metadata with the same name, then the old value is replaced.

Parameters:

metadata - location of the metadata

name - name of the metadata (e.g., META-INF/ejb.xml or META-INF/sun-ejb-jar.xml)

Throws:

NullPointerException - if metadata is null

IOException - if metadata does not exist.

IllegalArgumentException - if metadata is a directory.

toURI

public URI toURI()
          throws IOException

Get the deployable URI for this scattered archive.

Note : java.io.tmpdir is used while building the URI.

Returns:

Deployable scattered archive URI.

Throws:

IOException - if any I/O error happens while building the URI or while reading metadata, classpath elements, rootDirectory.
