Agenda
• What is OpenESB, GlassFish ESB?
• What can you do with OpenESB?
• The Open Source Community
Slide 2

What is OpenESB?
• OpenESB is an Open Source Community
• Goal of the community: an Open Source ESB for SOA &
Integration
• The product (the distribution) that's being built is called
GlassFish ESB
Slide 3

Example
a business problem that can be solved with OpenESB:
ERP
s y s te m
> Following an order from the ERP system
p o .c s v > ERP system creates a file with a batch of orders in CSV
re a d format
c o n v e rt > File needs to be picked up, read and converted to a canonical
p o .x m l format
A p p ro v a l > The CSV file does not contain all information necessary for
s y s te m the canonical format
> All orders in the CSV file need to be approved by an approval
p o .x m l
system
M o n it o r in g
s y s te m > Each order needs to be sent out to the Internet Gateway
c o n v e rt (TDN) in EDI format, or to a Fax gateway in PS format
p o .tx t > A financial monitoring application needs to get a copy of the
E m a il
order
N o t if y
> An email needs to be sent to the submitter of the order when
c o n v e rt
the order goes out
p o .e d i > The department that generally takes delivery of goods needs
TDN to be notified of the order

Aspects of a typical problem
• A complete integration is typically split up in several
interactions
• Each interaction is typically split up in several projects
• ... leading to hundreds of projects
• Each problem mixes:
> Message transformation
> Connectivity
> Business logic
• Goal:
> Make managing large number of projects doable
> Make building each project simple
> Avoid code duplication between projects by providing off-the-
shelf solutions for common problems Slide 6

OpenESB, the bits
• 100% Java
• Consists of a core runtime + components
• Components:
> processing engines, e.g. BPEL, XSLT,
Complex Event Processing
> Interfaces: HTTP, file, jms, database, ftp, SAP, CICS, ...
> Message transformation (different file formats)
• Large number of components (40+)
• Runtime: runs on GlassFish
> JBI Runtime, JBI components, EE components
• Design time: runs on NetBeans
> Many new editors, e.g. BPEL, WSDL, etc. Slide 7

OpenESB, the community
• Started in 2005
• Led by Sun Microsystems
• Many other partners (5+) and contributors:
> e.g. Advantech, Imola, ChainBuilder, eviware, Gestalt
• A lot of engineers working on Java CAPS, a proprietary
Sun product, are now working on OpenESB.
> ... causing a recent surge in activity in the community
• Sun is now providing commercial support on
GlassFish ESB
• A vibrant community
Slide 10

Commercial applications
• OpenESB bits are used in Java CAPS
• GlassFish ESB is commercially supported
• Third parties are using OpenESB as OEMs
