Introduction
...
Explain diff between std jbi component and lw component and the static use of ServiceMix.
See
http://docs.codehaus.org/display/SM/What+is+a+lightweight+component
...
...
a
...
good
...
explanation
...
of
...
the
...
different
...
types
...
of
...
JBI
...
components.
...
Two
...
main
...
use
...
cases
...
for
...
ServiceMix:
...
1.
...
As
...
a
...
ull
...
JBI
...
container
...
-
...
using
...
SMX
...
as
...
a
...
full
...
JBI
...
container
...
in
...
which
...
you
...
can
...
deploy
...
Service
...
Assemblies
...
and
...
standard
...
JBI
...
components.
...
And
...
you
...
may
...
also
...
deploy
...
lightweight
...
components
...
in
...
this
...
mode
...
-
...
they
...
must
...
be
...
deployed
...
to
...
the
...
servicemix-lwcontainer.
...
2.
...
Embedded
...
-
...
static
...
servicemix.xml
...
file
...
configuration
...
used
...
for
...
testing
...
or
...
encapsulating
...
ServiceMix
...
into
...
a
...
web
...
application
...
as
...
the
...
entire
...
use
...
of
...
ServiceMix.
...
In
...
other
...
words,
...
you
...
will
...
not
...
be
...
able
...
to
...
deploy
...
other
...
stuff
...
onto
...
this
...
type
...
of
...
ServiceMix
...
configuration
...
at
...
runtime.
...
You
...
would
...
have
...
to
...
shutdown,
...
reconfigure
...
and
...
then
...
restart.
...
This
...
tutorial
...
focuses
...
on
...
deploying
...
lightweight
...
components
...
to
...
the
...
servicemix-lwcontainer.
...
First
...
some
...
background.
...
A
...
JBI
...
component
...
is
...
either
...
a
...
service
...
engine
...
(SE)
...
or
...
a
...
binding
...
component
...
(BC).
...
These
...
terms
...
are
...
defined
...
in
...
...
...
...
and/or
...
the
...
...
.
...
A
...
BC/SE
...
is
...
installed
...
on
...
ServiceMix
...
by
...
copying
...
it
...
into
...
the
...
install
...
directory
...
which
...
resides
...
under
...
the
...
ServiceMix
...
home
...
directory.
...
So
...
what
...
gets
...
deployed?
...
JBI
...
components
...
can
...
act
...
as
...
containers
...
themselves.
...
Artifacts
...
can
...
be
...
deployed
...
to
...
an
...
existing
...
BC
...
or
...
SE
...
to
...
add
...
more
...
functionality
...
to
...
that
...
component.
...
Adding
...
artifacts
...
to
...
installed
...
components
...
is
...
called
...
deployment.
...
To
...
deploy
...
artifacts
...
to
...
a
...
component
...
the
...
artifacts
...
can
...
be
...
placed
...
in
...
the
...
deploy
...
directory
...
under
...
the
...
ServiceMix
...
home
...
directory.
...
Another
...
term
...
that
...
is
...
important
...
to
...
know
...
is
...
service
...
assembly
...
.
...
A
...
service
...
assembly
...
is
...
a
...
collection
...
of
...
deployment
...
artifacts
...
and
...
metadata.
...
A
...
service
...
unit
...
is
...
a
...
single
...
deployment
...
artifact
...
which
...
is
...
deployed
...
on
...
a
...
single
...
component.
...
For
...
deployment
...
to
...
happen,
...
the
...
artifacts
...
must
...
be
...
in
...
a
...
very
...
specific
...
format,
...
which
...
is
...
specified
...
in
...
the
...
JSR
...
208
...
specification.
...
Please
...
see
...
chapter
...
6
...
of
...
the
...
...
...
specification
...
for
...
more
...
details.
...
In
...
addition
...
to
...
deploying
...
components,
...
ServiceMix
...
allows
...
servicemix.xml
...
files
...
to
...
be
...
deployed
...
in
...
a
...
similar
...
method
...
to
...
deploying
...
a
...
component.

Explanation
...
of
...
Using
...
the
...
Lightweight
...
Container
...
and
...
Deploying
...
the
...
ServiceMix
...
Loan
...
Broker
...
Example
...
We
...
are
...
going
...
to
...
use
...
the
...
Loan
...
Broker
...
example
...
which
...
can
...
be
...
found
...
...
...
...
...
...
.
There are several things to note about this example. First of all it is meant to be run stand-alone.
...
Specifically,
...
when
...
running
...
this
...
example,
...
ServiceMix
...
will
...
be
...
started
...
for
...
you,
...
then
...
the
...
loan
...
broker
...
is
...
deployed
...
and
...
run.
...
Therefore,
...
there
...
is
...
a
...
servicemix.xml
...
file
...
in
...
the
...
loan-broker
...
directory.
...
This
...
servicemix.xml
...
file
...
is
...
used
...
for
...
configuring
...
the
...
ServiceMix
...
JBI
...
container
...
upon
...
ServiceMix
...
starting
...
up.
...
This
...
is
...
not
...
to
...
be
...
confused
...
with
...
the
...
servicemix.xml
...
located
...
in
...
the
...
loan-broker\src\su
...
directory.
...
The
...
SU
...
servicemix.xml
...
file
...
is
...
used
...
to
...
configure
...
the
...
servicemix-lwcontainer
...
.
...
Every
...
service
...
unit
...
must
...
contain
...
some
...
kind
...
of
...
configuration
...
file.
...
For
...
example,
...
if
...
we
...
were
...
creating
...
a
...
service
...
unit
...
for
...
the
...
BPEL
...
service
...
engine
...
there
...
would
...
also
...
be
...
a
...
configuration
...
file,
...
but
...
it
...
would
...
not
...
be
...
a
...
servicemix.xml
...
file,
...
such
...
as
...
the
...
one
...
used
...
for
...
configuring
...
the
...
lightweight
...
container.
...
NOTE:
...
There
...
are
...
two
...
major
...
phases
...
to
...
creating
...
a
...
lightweight
...
component
...
that
...
is
...
ready
...
for
...
deployment:
...
one,
...
is
...
the
...
development
...
phase
...
of
...
the
...
component,
...
which
...
includes
...
coding
...
and
...
compiling
...
and
...
building
...
the
...
code,
...
the
...
second
...
phase
...
is
...
creating
...
the
...
packaging
...
necessary
...
for
...
the
...
component
...
to
...
be
...
installed
...
onto
...
the
...
JBI
...
container.
...
This
...
document
...
will
...
focus
...
on
...
the
...
second
...
part.
...
Any
...
steps
...
relating
...
to
...
compilation
...
are
...
simply
...
performed
...
here
...
to
...
get
...
us
...
to
...
the
...
point
...
that
...
we
...
can
...
assemble
...
the
...
component
...
into
...
a
...
JBI
...
service
...
assembly
...
or
...
service
...
unit.
...
The
...
following
...
example
...
shows
...
several
...
lightweight
...
components
...
(which
...
make
...
up
...
the
...
loan
...
broker
...
example)
...
being
...
deployed.
...
These
...
steps
...
were
...
performed
...
with
...
a
...
source
...
distribution
...
of
...
ServiceMix
...
3.x
...
on
...
Windows
...
XP.
...
Although
...
we
...
are
...
not
...
covering
...
the
...
component
...
development
...
phase
...
in
...
this
...
case
...
we
...
do
...
need
...
to
...
perform
...
a
...
compile.
...
We
...
will
...
use
...
Apache
...
Ant
...
to
...
compile
...
the
...
loan-broker
...
demo
...
components:
| Code Block |
|---|
} cd [servicemix_dir]\examples\loan-broker ant build-components {code} |
This
...
will
...
compile
...
the
...
Java
...
code
...
and
...
put
...
the
...
Java
...
class
...
files
...
into
...
the
...
loan-broker\build\loanbroker\components
...
directory.
...
Now
...
we
...
are
...
ready
...
to
...
assemble
...
the
...
components
...
together.
...
The
...
loan
...
broker
...
demo
...
supplies
...
us
...
with
...
the
...
build.xml
...
file
...
(which
...
was
...
used
...
in
...
the
...
compile
...
step
...
above).
...
The
...
build.xml
...
contains
...
targets
...
for
...
creating
...
service
...
units.
...
If
...
you
...
run
...
"ant
...
setup"
...
the
...
service
...
unit
...
will
...
automatically
...
be
...
created.
...
Ultimately,
...
this
...
is
...
what
...
you
...
will
...
want
...
to
...
do,
...
however,
...
the
...
following
...
procedure
...
gives
...
the
...
manual
...
steps
...
for
...
creating
...
a
...
service
...
unit
...
and
...
service
...
assembly,
...
to
...
facilitate
...
in
...
understanding
...
the
...
contents
...
of
...
a
...
SUs
...
and
...
SAs.
...
- First
...
- create
...
- the
...
- service
...
- unit.
...
- The
...
- service
...
- unit
...
- is
...
- a
...
- ZIP
...
- file
...
- that
...
- will
...
- contain
...
- your
...
- application's
...
- Java
...
- class
...
- files.
...
- For
...
- example:
- Use a ZIP compression tool, such as Winzip or gzip to create a zip file containing the classes in servicemix_dir\examples\loan-broker\build\loanbroker\components. The zip file name is arbitrary, but to match the example call it
loanbroker-su.zip.
- Use a ZIP compression tool, such as Winzip or gzip to create a zip file containing the classes in servicemix_dir\examples\loan-broker\build\loanbroker\components. The zip file name is arbitrary, but to match the example call it
--------------------------------------------------------------------------------------
- Two jar files must be created. These jar files will be copied into the ServiceMix
deploydirectory. The first jar file will contain the service componentjbi.xmlfile. When this is copied to thedeploydirectory it deploys theServiceMixComponentcomponent. The second jar file will contain the service assembly and thejbi.xmldescriptor file. When it is copied to thedeploydirectory of ServiceMix it deploys the service unit (Quartz) to the previously deployed component,ServiceMixComponent.- The file service component
jbi.xmlfile should contain:Code Block <jbi xmlns="http://java.sun.com/xml/ns/jbi" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/jbi" version="1.0"> <component type="service-engine"> <identification> <name>servicemix-component</name> <description>A ServiceMix Component that can be used to deploy servicemix.xml artifacts.</description> </identification> <component-class-name>org.servicemix.components.servicemix.ServiceMixComponent</component-class-name> <component-class-path/> </component> </jbi>
- The file service component
...
- Put
jbi.xml
...
- in
...
- an
...
- empty
...
- META-INF
...
- directory
...
- and
...
- put
...
- that
...
- into
...
- a
...
- jar
...
- file:
...
Code Block
...
mkdir META-INF copy jbi.xml META-INF jar cvf service-component.jar *
...
- Create a zip file of the
servicemix.xml
...
- file
...
- you
...
- modified
...
- above.
...
- The
...
- zip
...
- file
...
- should
...
- contain
...
- the
...
servicemix.xml
...
- file
...
- and
...
- it
...
- should
...
- be
...
- called
...
- su1.zip
...
- to
...
- match
...
- the
...
- name
...
- it
...
- is
...
- called
...
- in
...
- the
...
jbi.xml
...
- file.
...
- See
...
- the
...
artifacts-name
...
- tag
...
- in
...
- the
...
jbi.xml
...
- file
...
- for
...
- the
...
- name
...
- of
...
- the
...
- zip
...
- file.
...
- Create
...
- the
...
- second
...
- jar
...
- file--this
...
- is
...
- the
...
- service
...
- assembly
...
- jar
...
- file.
...
- It
...
- will
...
- contain
...
- another
...
jbi.xml
...
- file
...
- that
...
- is
...
- used
...
- for
...
- the
...
- service
...
- assembly
...
- and
...
- it
...
- will
...
- also
...
- contain
...
- the
...
- zip
...
- file,
...
su1.zip
...
- in
...
- the
...
- following
...
- structure:
...
The
...
- service
...
- assembly
...
jbi.xml
...
- should
...
- be
...
- match
...
- the
...
- following:
...
Code Block
...
<jbi xmlns="http://java.sun.com/xml/ns/jbi" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/jbi" version="1.0"> <service-assembly> <identification> <name>AU_1</name> <description>Sample AU</description> </identification> <service-unit> <identification> <name>SU_1</name> <description>Sample</description> </identification> <target> <artifacts-zip>su1.zip</artifacts-zip> <component-name>servicemix-component</component-name> </target> </service-unit> </service-assembly> </jbi>
...
Copy thejbi.xml
...
- file
...
- to
...
- an
...
- empty
...
- META-INF
...
- directory,
...
- then
...
- create
...
- the
...
- jar
...
- file:
...
Code Block
...
In a directory which contains these files, create the jar file: META-INF/jbi.xml su1.zip jar cvf sa_quartz.jar *
...
Wiki Markup Deploy the two jar files. Copy {{service_component.jar}} and {{sa_quartz.jar}} to {{\[servicemix_src_install_dir\]\assembly\target\servicemix-2.0.\bin\servicemix-2.0.2\deploy}}. This can be done while ServiceMix is running or while ServiceMix is not running. In the second case, run ServiceMix to see the deployment. Output will be similar to:
...
Code Block
...

The JBI spec describes in detail how to create a valid JBI deployment unit. In essence, it is a jar file with a META-INF/jbi.xml
...
with
...
other
...
resource
