Here is the typical structure of a SA project.
{noformat}
src
main
java
jbi
jbi.xml
pom.xml
{noformat}
SA projects are associated with a builder in charge of validating the jbi.xml file.

h1. Creation
The creation of a SA project can be achieved by:
* Using the Petals Service Assembly wizard (*File > New > Petals > Service Assembly project*).
* Generating concrete projects from a _croquis_.
* Importing an existing Service-Assembly.
A SA project makes sense in only two situations:
* You want to package SU projects with Maven.
* You want to create complex service assemblies, which embed several service-units.
\\
To create a SA project, select *File > New > Petals > Service Assembly project* and click *Next*.

This wizard has only one page.

\\
Fill-in the *name* and *artifact ID*.
Update the *version* and the *group ID* before clicking *Finish*.
A SA project is created and visible under the *Service Assembly projects* category.
h1. Edition and update
A SA project has a specific structure when seen in the Petals Projects view.
{noformat}
SA Project
SU Project 1
...
SU Project n
jbi.xml
pom.xml
{noformat}
\\
Notice the real file structure is:
{noformat}
SA Project
src
main
jbi
jbi.xml
pom.xml
{noformat}
\\
The Petals Projects view simply (and only) presents a different point of view.
*To add or remove SU projects from a SA projects, you must edit the jbi.xml* and (sometimes) [update the *dependencies* in the pom.xml|Preparing Maven Compatibility#SaMavenDependencies].
Once the jbi.xml is saved, a builder validates it and updates the project dependencies. The Petals Projects view is updated right after this build.
h1. {anchor:Export} Export for Petals
{tip}
SU and SA projects are compatible with the Petals Maven plug-in.
The packaging can be done with both the Studio and Maven.
{tip}
h2. {anchor:FastExport} Fast export
The fast export is a shortcut to create a service assembly from a SA project in few seconds.
The created service assembly is saved at the root of the SA project.
To export a SA project quickly, right-click it and select *Petals > Fast Export for Petals*.

h2. Complete export
The complete export provides numerous options to export one or several SA projects at once.
Select *File > Export > Petals > Service Assembly*.

A wizard starts.
The top part lists all the SA projects contained in the workspace. Select the ones you want to export and the export mode.

h3. Distinct export, in the project directories
Every selected SA project will be exported, each one as a service assembly.
Each created service assembly is placed in the SA project. This is equivalent to making a [Fast export|#FastExport] on every selected SA project.

h3. Distinct export, in a same directory
Every selected SA project will be exported, each one as a service assembly.
All the service assemblies are placed in a same directory. The directory location must be specified.
