WSO2 Webinar - Business Processes with Human Smarts


What is a business process? A series of steps that need to be performed in order to provide goods or services. Processes that used to be performed by humans are becoming increasingly automated by enterprise IT, allowing them to be performed more quickly and reliably and at much greater scale. But there can be unintended consequences - reverberation of failures, lack of accountability, an inability to handle situations outside the norm.
So why are business processes challenging to get right? Getting it right often means striking a good balance between automation and using the wisdom and flexibility of the human mind. But the technologies and systems for automating interactions which include humans differs substantially from automating interactions among software applications. This gulf has been difficult to bridge. Until now.
The recent introduction of two new standards in this space - BPEL4People and WS-Human Task - enables organizations to extend automated systems smoothly to include human interaction. WSO2 supports these new capabilities in the latest release of the WSO2 Business Process Server.
Your presenter, Milinda Pathirage, will cover the following topics:
Scenarios highlighting business process involving humans
Insights into BPEL4People and WS-Human Tasks
Overview of the WSO2 Business Process Server
Review of the new human-interaction features of the latest version of the WSO2 BPS
Who should attend:
Architects and developers expanding their toolkit to include business processes
Business process analysts
Consultants and analysts specializing in SOA
Milinda Pathirage is product manager for the WSO2 Business Process Server and is an active contributor for Apache ODE project. He brings a wealth of knowledge on business processes and how enterprises leverage these technologies today.

How to write a BPEL extension for WSO2 BPS 1.1.0 and Apache ODE

You may always wanted to write your own BPEL activity to handle your scenario. This article will go through step by step process to implement a simple BPEL extension activity for WSO2 BPS and Apache ODE.
WSO2 Business Process Server (BPS) is an easy-to-use open source business process server that executes business processes written using the WS-BPEL standard. It is powered by Apache ODE (open source BPEL engine) and provides a complete Web-based graphical console to deploy, manage and view processes in addition to managing and viewing process instances.

Implementation of Extension Bundle

Create a class by implementing one of the ExtensionOperation interfaces which are available at [1]. The run* method of this class should contain the implementation of the extension activity. You can find a sample implementation of this class at [2].
Then You have to create a class by implementing AbstractExtensionBundle interface. Within this class, the above implemented ExtensionOperation class should be registered. A sample implementation can be found at [3].

Configure WSO2 BPS

There are two methods to expose the extension classes to BPS.
  • Creating a jar.

    Copy the jar to BPS_HOME/repository/components/lib directory.
  • Creating an OSGI bundle

    Copy the bundle to BPS_HOME/repository/components/dropins directory.
Add the following configuration entry to the bps.xml file in BPS_HOME/conf directory. Repalce org.wso2.bps.samples.extension by your extension class name.
Note: By default, the sample extension bundles shipped with WSO2 BPS are copied to BPS_HOME/repository/components/lib. You have to add the following configuration to get them registered in BPS.
<bps xmlns="http://wso2.org/bps/config">
...
<extensionBundles>
<runtimes>
<runtime>org.wso2.bps.samples.extension</runtime>
</runtimes>
</extensionBundles>
...
</bps>
Now, restart WSO2 BPS sever, and you are ready to use the new extension in your BPEL.

The process is almost the same for Apache ODE. But there is a separate configuration file to register the extension. Please refer ODE extensions documentation for more details.

Using the Extension activity in your BPEL

The extension must be declared before, it is used.
<bpel:process...>

<bpel:extensions>
<bpel:extension namespace="#extension-namespace#" 
                        mustUnderstand="yes|no"/>
</bpel:extensions>

...
</bpel:process>
If the mustUnderstand attribute is set to yes, then the extension should be registered in BPS server in order to deploy the BPEL process. Otherwise, it will throws an error at the compilation stage of the process. If the mustUnderstand attribute is set to no, then the BPEL process will be deployed without checking whether there is an extension registered in the server.

Using the activity. According to the sample anyElementQName should be equal to b4ptest
<extensionActivity>
<anyElementQName standard-attributes>
standard-elements
</anyElementQName>
</extensionActivity>
You can find a sample BPEL process at TestExtensionActivity.zip

Deploy Intalio Tempo in Apache Tomcat 5

Now you can try WSO2 BPS 2.0.0 which offers you to deploy human tasks written in WS-HumaTasks standard as well as Business  Processes written in WS-BPEL standard. You can also integrate human tasks within the business  processes according to WS-BPEL4People standard. You can start the server as a stand-alone server, so that no need to go through hard configuration stuff. WSO2 BPS 2.0.0 is open source product. Check release note

Recently, I tried to deploy Intalio Tempo in standalone Apache Tomcat 5.5.xx. Tempo provides a ruby build script (tempo_builder.rb) to provide a Tempo integrated in to a Apache Tomcat server. But, what I required was different scenario. I needed to deploy Tempo in my own Tomcat server.
It took few days for me to deploy Tempo in a standalone Tomcat server. Therefore, I thought of sharing the experience I gained, in-order to minimise the pain of people who are in need of deploying Tempo in Tomcat.
Please note well, this document may not be the best way to deploy Tempo in Tomcat. Therefore, please let me know, if you got to know a better way.

First of all, make sure that all the required software are properly installed. Refer INSTALL.txt to find the required software. If you intend to build Apache ODE, then you have to aware about the Buildr and the Java version. In case if you need help on this, refer this post. Make sure that you install the Buildr version 1.3.3 instead of 1.3.2 to support both ODE and Tempo.

checkout the source of Tempo
git clone git://github.com/intalio/tempo.git

Build the Tempo (according to the building instructions of Tempo )
buildr package

In case, if you have installed Buildr in both Ruby and jRuby, make sure to prefix jruby -S or ruby -S to select between the installed Buildrs.

Build the Tempo (to build the dependency jars, BPEL processes and axis2 services)
run the script TEMPO_CHECKOUT/rsc/scripts/tempo_builder.rb
refer INSTALL.txt for further details

From this onwards:
TEMPO_TOMCAT refers to the Tomcat directory created by the tempo_builder.rb script.
TOMCAT_HOME refers to the standalone Tomcat server in which Tempo should be deployed.

Copy the following
TEMPO_TOMCAT/bin/setenv.sh to TOMCAT_HOME/bin
TEMPO_TOMCAT/var to TOMCAT_HOME/

Edit TOMCAT_HOME/conf/context.xml and add the following in to the <context> element
<resourcelink global="jdbc/BPMSDB" name="jdbc/BPMSDB" type="javax.sql.DataSource"/>
<resourcelink global="DeployRegistry" name="registry/DeployRegistry" type="org.intalio.deploy.registry.Registry"/>
<transaction factory="">TomcatGeronimoTxFactory" />

Edit TOMCAT_HOME/conf/server.xml and add the following to the <globalnamingresources> element
<resource name="jdbc/BPMSDB" auth="Container" type="javax.sql.DataSource" maxactive="100" maxidle="30" maxwait="10000" username="root" password="password" driverclassname="jdbc.Driver" url="jdbc:mysql://localhost:3306/bpms?relaxAutoCommit=true"/>
<resource name="registry/DeployRegistry" auth="Container" type="registry.Registry" factory="org.intalio.deploy.registry.RegistryObjectFactory" />

Edit TOMCAT_HOME/conf/web.xml and add the following to the element <web-app>
<resource-ref>
<res-ref-name>jdbc/BPMSDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

Install MySQL Server and create the database "bpms" and create the schema as in TEMPO_TOMCAT/bpms.sql
create database bpms;
use bpms;
source TEMPO_HOME/bpms.sql;


Copy the MySQL connector jar to TOMCAT_HOME/common/lib

Copy the additional jars in the TEMPO_TOMCAT/common/lib to the TOMCAT_HOME/common/lib
deploy-registry-1.0.3.jar
slf4j-api-1.4.3.jar
slf4j-log4j12-1.4.3.jar
log4j-1.2.15.jar

Deploy Axis2 (1.4.1) and ODE (1.3.2) in your standalone Tomcat Server

Deploy the following web services which are in the TEMPO_CHECKOUT's respective target directories, in Axis2.
tempo-tas-service-5.x.x.x.aar
tempo-tms-service-5.x.x.x.aar

Also deploy the following web services which can be found in TEMPO_TOMCAT/webapps/axis2/WEB-INF/
servicesdeploy-ws-service-1.0.3.aar
security-ws-service-1.0.1.aar

Copy the following jars in TEMPO_TOMCAT/webapps/ode/WEB-INF/lib to the TOMCAT_HOME/webapps/ode/WEB-INF/lib
deploy-api-1.0.3.jar
ode-ext-deploy-1.0.0.jar
tempo-processes-xpath-extensions-6.0.6.jar

Then deploy the following .war files that can be found in respective target directories of TEMPO_CHECKOUT directory.
fds.war
ui-fw.war
wds.war

Then Deploy the xFormsManager.war. It is possible to build it from the source (git clone git://http://github.com/intalio/xforms-manager.git) or download the war file

Now you are ready to use Tempo in your Tomcat server. Please feel free to point out the mistakes in this post as well as your problems regarding deployment.
