Welcome to Beehive
==================
To build Beehive, you will first need to check the source out from
Apache SVN and then install / configure required external software and
your shell environment.
Checkout Beehive from SVN
=========================
To do this, run the command:
svn checkout https://svn.apache.org/repos/asf/beehive/trunk
After running this command, you should have a directory "trunk/" which
contains the current Beehive source. If you ran this command in:
d:\java\beehive
you should have the directory:
d:\java\beehive\trunk
In the following steps, we'll refer to this as ${beehive.home}.
Install / configure external software and setup your shell
==========================================================
1) Java 5
Download: http://java.sun.com/j2se/1.5.0/download.jsp
Install Java 5 and set the JAVA_HOME environment variable to
refernce the JDK install directory. Ensure that $JAVA_HOME/bin is
available in your $PATH.
2) Ant 1.6.2+
Download: http://ant.apache.org/bindownload.cgi
Ant 1.6.2 is the minimum version required to build Beehive. Install
Ant 1.6.2 and set the ANT_HOME environment variable to reference the
Ant install directory. Ensure that $ANT_HOME/bin is available in your
$PATH. Copy junit.jar (in external/junit/) to $ANT_HOME/lib. This step is
required in order for the Ant <junit> tasks to work correctly.
3) Tomcat 5.0.x
Download: http://jakarta.apache.org/site/binindex.cgi#tomcat
Tomcat is used as the default test environment for Beehive. Install
Tomcat and set the CATALINA_HOME environment variable to reference the
Tomcat install directory. If you're installing Tomcat on Linux,
be sure to set the execute bit on the shell scripts in $CATALINA_HOME/bin.
If you installed these into d:\java, your environment variables
might look something like:
JAVA_HOME=d:\java\jdk1.5.0
CATALINA_HOME=d:\java\jakarta-tomcat-5.0.25
ANT_HOME=d:\java\apache-ant-1.6.2
Configure installed products
In order to run the Beehive tests, ensure that Tomcat has the the
"manager" role is defined in ${CATALINA_HOME}/conf/tomcat-users.xml
with a "manager" role and manager username/password of manager/manager.
This step is required in order to use the Tomcat Ant tasks to deploy
applications to Tomcat. An example of this file is available here:
${beehive.home}/test/conf/tomcat-users.xml
In the following examples, '$>' is your propmpt at $BEEHIVE_HOME, so if
you see '$>ant', type 'ant' (without the quotes) and press [enter].
In addition to the external software installed above, Beehive requires
one additional JAR to provide JSR 173 support for StAX, which is
required by XMLBeans. This JAR is downloaded from the network when
running Beehive's "bootstrap" target, so be sure to have a network
connection for your first build. A network connection is not required
for any subsequent builds. To install the JSR 173 API, run:
$>ant bootstrap
To check your Beehive build setup, run:
$>ant check.setup
This should end with "BUILD SUCCESSFUL" if you see any failures, be
sure to re-check your setup steps above.
To build Beehive, run:
$>ant clean deploy
To run the Beehive tests, run:
$>ant drt
Using Proxies With a Beehive Build
====================================
If you need to use proxies you can setup additional environment variables
so that the Ant "bootstrap" target is successful in downloading the
JSR 173 API JAR file.
PROXYHOST=<name of proxy host>
PROXYPORT=<port used for proxying>
PROXYUSER=<username for proxy authentication>
PROXYPASSWORD=<password for proxy authentication>
NONPROXYHOSTS=<hosts that should not be proxied>
SOCKSPROXYHOST=<socks proxy host name>
SOCKSPROXYPORT=<socks proxy port>
At a minimum, you will need to set PROXYHOST and PROXYPORT if your
network environment requires a proxy connection. To set these
environment variables in your shell, run:
set PROXYHOST=<name of proxy host>
in a Windows shell and
export PROXYHOST=<name of proxy host>
in a UNIX shell.
For information on proxy support using the <setproxy> task, please
visit http://ant.apache.org/manual/OptionalTasks/setproxy.html
Building Beehive documentation
=============================
The following documentation-related targets in
beehive/trunk/build.xml require that you have
Apache Forrest installed locally:
$>ant docs
$>ant build.dist
Before running these targets, complete the following steps.
1) Download and install Forrest 0.7 on your machine.
A list of available download locations is available at:
http://forrest.apache.org/mirrors.cgi
2) Copy the JAR file
apache-forrest-0.7/lib/core/xml-commons-resolver-1.1.jar
into
$ANT_HOME/lib
(This allows the Ant targets to call Forrest tasks.)
3) Ensure that FORREST_HOME is set to the following path.
On Windows machines:
set FORREST_HOME=C:\MyApacheStuff\apache-forrest-0.7
On Unix machines:
export FORREST_HOME=/MyApacheStuff/apache-forrest-0.7
4) Set the PATH as follows:
On Windows machines:
set PATH=%FORREST_HOME%\bin;%PATH%
On Unix machines:
export PATH=$FORREST_HOME/bin:$PATH
You are now ready to run these targets:
$>ant docs
$>ant build.dist

Developing in Beehive
=====================
Hey; we're glad you're here! If you're interested in developing Beehive, the
information below is for you. First, make sure you've read the introduction
for Beehive contributors here:
http://wiki.apache.org/beehive/For_Beehive_Developers
This should help you get started setting up Beehive in your IDE and navigating
what code is where.
You'll also need to configure your Subversion client to handle end-of-line styles
correctly. To do this, follow the directions below.
Configuring your Subversion client
==================================
Every text file must have the svn:eol-style property set to 'native'. This
causes ends-of-line to be translated to the correct format for the local
operating system when files are checked out (e.g., LF on linux, CR/LF on
Windows). You can do this on a per-file basis using the 'svn propset' command:
svn propset svn:eol-style native <file path>
An easier way to ensure that all added files have the right properties set is
to use the "auto-props" feature in the SVN client configuration file. The
location of this file varies depending on the operating system (see
http://svnbook.red-bean.com/svnbook/book.html#svn-ch-7-sect-1).
On Linux/UNIX it is located:
~/.subversion/config
On Windows, it is typically located in a hidden directory:
%SYSROOT%\Documents and Settings\<user name>\Application Data\Subversion
If you have problems locating this, make sure you can view hidden directory
contents.
Confirm the "header" named [miscellany] is uncommented.
Then, add (uncomment) the following line under the "[miscellany]" section:
enable-auto-props = yes
Then, add (uncomment) an "[auto-props]" section (include the [auto-props]
header as well) with a list of file extensions that will automatically
trigger the svn:eol-style=native property:
[auto-props]
*.txt = svn:eol-style=native
*.java = svn:eol-style=native
*.jj = svn:eol-style=native
*.xml = svn:eol-style=native
*.xsd = svn:eol-style=native
*.xsdconfig = svn:eol-style=native
*.dtd = svn:eol-style=native
*.properties = svn:eol-style=native
*.jcs = svn:eol-style=native
*.jcx = svn:eol-style=native
*.jpf = svn:eol-style=native
*.jpfs = svn:eol-style=native
Global.app = svn:eol-style=native
*.jsp* = svn:eol-style=native
*.jspx = svn:eol-style=native
*.jspf = svn:eol-style=native
*.jsf = svn:eol-style=native
*.jsfb = svn:eol-style=native
*.faces = svn:eol-style=native
*.tld = svn:eol-style=native
*.tldx = svn:eol-style=native
*.tag = svn:eol-style=native
*.tagf = svn:eol-style=native
*.html = svn:eol-style=native
*.css = svn:eol-style=native
*.js = svn:eol-style=native
*.inc = svn:eol-style=native
*.sh = svn:eol-style=native;svn:executable
*.cmd = svn:eol-style=native
*.pl = svn:eol-style=native
*.py = svn:eol-style=native
*.beaninfo = svn:eol-style=native

This directory contains the Beehive Controls source and test files. This
README provides an overview of the basic directory structure, and describes
some of the useful ant targets for building, generating javadoc, and running
tests for the Controls runtime.
SOURCE DIRECTORY STRUCTURE:
./src:
Contains all of the source files for the Beehive Controls runtime. When the
runtime is built, all of the generated classes end up in
build/jars/controls.jar.
./src/api:
Contains all of the source files for Controls public APIs used by Control
authors or clients. All annotation type, interfaces, and classes in the public
API set live within the org.apache.beehive.controls.api.* package space.
./src/spi:
Contains a small set of service provider interfaces used to adapt or
extend the Controls runtime for a specific environment. The audience for
the SPI set is primary system developers who want to integrate the runtime
into a specific container or application server environment, implement a
specific type of interceptor or instantiation factory, etc. All of the
classes in the SPI set live within the org.apache.beehive.controls.spi.*
package space.
./src/runtime:
Contains the Control runtime implementation classes. There are several
base classes used for code-generated ControlBeans as well as supporting
runtime classes for properties, contextual services, container integration,
etc. Control authors or clients should never reference any of these
runtime classes directly. All of the runtime classes live within the
org.apache.beehive.controls.runtime.* package space.
SOURCE DEPENDENCIES:
The dependencies across the various types of Control sources are:
api -> spi : API public factory classes depend upon some SPI interfaces
spi -> api : the SPI classes often consume public classes
runtime -> api, spi : the runtime classes reference both API and SPI types
Note: there are *no* dependencies from public interfaces to runtime classes.
This relationship is enforced by actually having them compile separately
(api + spi first, then runtime).
SOURCE ANT TARGETS
This section describes some of the available ant targets from the Controls
root directory.
ant build:
Compiles all annotation type, interface, and class files in the API, SPI, and
runtime directory and creates build/jars/controls.jar to contain them.
ant docs:
Generates javadoc documention for all API, SPI, and runtime classes and puts
them in build/docs. After running this target, you can browse to
file:build/docs/apidocs/classref_controls/index.html to view them.
ant clean:
Removes all generated output files from any of the build targets in the top
level or test directories.
TEST INFRASTRUCTURE:
The Controls runtime test infrastructure lives under the test subdirectory. It
includes a variety of test for Controls running in different context, from
vanilla Junit/java tests to running Controls inside of the various containers
that are part of the Beehive programming model: JWS, JPF, and nesting inside
of other controls. More details about the Controls runtime test tools
can be found at http://wiki.apache.org/beehive/Controls/TestingControls.
CONTROLS TEST TARGETS:
There are two main test targets for running Controls tests. These should be run
from within the controls/test directory:
ant checkin.tests:
These are a set of checkin tests that do shallow testing of a broad range of
functionality. These should be run and pass 100% before a committer submits
any Controls runtime changes.
ant detailed.tests:
This runs all control tests. Since some of them are test cases that are the
basis of open JIRA issues, THESE TESTS ARE NOT EXPECTED TO PASS 100%. Currently,
there is no good filter for running the detailed tests that are expected to
pass, but it has been suggested that this would be a good thing (to enable
deeper testing of larger changes).

/**
* The ResourceContext interface defines a basic contextual service for coordinating the
* resource utilization of a control implementation within a resource scope defined external
* to the control. This contextual service that provides assistance to a Control in managing
* any external resources (connections, sesssions, etc) that may be relatively expensive to
* obtain and/or can only be held for a relatively short duration.
* <p>
* A ResourceContext implementation may be provided by an external container of Controls, such
* as a servlet engine or EJB container, that coordinates the resource lifecycle of controls with
* the activities of the external container. For example, the resource scope for a
* ResourceContext provider associated with the web tier might enable control resources to be
* used for the duration of a single http request; for the EJB tier it might mean for the
* lifetime of the current EJB invocation or active transaction.
* <p>
* A control implementation participates in this resource management contract by declaring a
* ResourceContext instance annotated with the
* <sp>@Context annotation, the standard service provider model of the Control runtime will
* associate the control instance with a ResourceControl provider implementation that is
* associated with the current execution context. This is demonstrated by the following
* code excerpt from a ControlImplementation class:
* <p>
* <pre><code>
* <sp>@org.apache.beehive.controls.api.bean.ControlImplementation
* public class MyControlImpl
* {
* ...
* // Declare need for resource mgmt support via the ResourceContext service
* <sp>@org.apache.beehive.controls.api.context.Context
* ResourceContext resourceContext;
* ...
* </code></pre>
* <p>
* Once the control has been associated with a ResourceContext provider, the provider will
* deliver events to the Control Implementation instance according to the following basic
* contract:
* <p>
* <ul>
* <li>the ResourceContext provider notifies a control implementation when it should acquire its
* resources using the onAcquire event.
* <li>the ResourceContext provider notifies a control implementation when it should release its
* resources using the onRelease event.
* </ul>
* <p>
* The following code fragment shows how to receive resource events from within a Control
* implementation:
* <p>
* <pre><code>
* import org.apache.beehive.controls.api.events.EventHandler;
*
* ...
*
* <sp>@EventHandler(field="resourceContext",
* eventSet=ResourceContext.ResourceEvents.class,
* eventName="onAcquire")
* public void onAcquire()
* {
* // code to obtain connections/sessions/...
* }
*
* <sp>@EventHandler(field="resourceContext",
* eventSet=ResourceContext.ResourceEvents.class,
* eventName="onRelease")
* public void onRelease()
* {
* // code to release connections/sessions/...
* }
* </code></pre>
* <p>
* The onAcquire resource event is guaranteed to be delivered once before any operation declared
* on a public or extension interface associated with the control. This event will be delivered
* once, and only once, within a particular resource scope associated with the ResourceContext.
*
* If a control needs to utilize its resources in another context (such as in response to a
* PropertyChange notification), the ResourceContext also provides support for manually
* acquiring and releasing resources.
*
* @see org.apache.beehive.controls.api.context.ResourceContext.ResourceEvents
* @see org.apache.beehive.controls.api.context.Context
* @see org.apache.beehive.controls.api.events.EventHandler

* <b>contextFactoryClassname</b>: fully qualified classname of a factory class that implements
* {@link org.apache.beehive.controls.api.assembly.ControlAssemblyContext.Factory}. Typically this
* would depend on the type of module on which assembly is being run (EJB, webapp, etc). Different
