In the scope of this page, we will use the version 1.0 of the component.
Click *Next*. The next page gives you the choice between 3 creation ways.
h1. Creating a new empty BPEL process
On the next page, select *Create a new BPEL process*.
!petals-studio-create-bpel-3.jpg!
Click *Next*.
\\
The next page expects the project name.
The process name will be extracted from it.
!petals-studio-create-bpel-4.jpg!
Click *Finish*.
\\
The project is created.
It contains a basic BPEL process...
!petals-studio-create-bpel-sketch-6.jpg!
\\
... with a WSDL definition and an Artifacts WSDL.
!petals-studio-create-bpel-sketch-5.jpg!
h1. Starting from an existing BPEL
On the next page, select *Import an existing BPEL process*.
Indicate the BPEL URL, or use the *Browse...* button to select the BPEL file on the local disk.
!petals-studio-create-bpel-7.jpg!
Click *Next*.
\\
The next page expects the project name.
By default, it is created from the name of the imported process.
!petals-studio-create-bpel-8.jpg!
Click *Finish*.
\\
The project is created.
It contains the imported BPEL process...
!petals-studio-create-bpel-sketch-10.jpg!

This name will also act as the process name.
By default, it is generated from the WSDL name.
!petals-studio-create-bpel-12.jpg!
Click *Finish*.
\\
The project is created.
It contains a BPEL process that was generated from the WSDL definition...

In fact, the WSDL definition contains a lot of operations.
To make it readable, the BPEL designer switched to the horizontal layout.
