On the left side of this figure is a rectangle labeled "Oracle WebLogic Server." Inside Oracle WebLogic Server is another rectangle labeled "SOA Infrastructure Java EE application." Inside the SOA Infrastructure Java EE application are five rectangles, organized vertically.

The five rectangles, starting from the top rectangle and ending at the bottom rectangle, include the following labels:

• Composite Deployment

• Composite Metadata Management

• Service Engines (Mediator, BPEL, Workflow...)

• Composite Management (instantiation, targeting to BPEL, Mediator, etc....)

• Task Control Services: thread assignment, processing of requests

Below the bottom of the five rectangles is an arrow labeled "Coherence infrastructure for deployment across cluster."

To the right and outside of the Oracle WebLogic Server rectangle, there are four additional rectangles, organized vertically.

These four rectangles are described as follows, starting from the top rectangle and ending at the bottom rectangle:

• The top rectangle is labeled "Deploying clients." An arrow starts at this rectangle and points to the "Composite Deployment" label inside the "SOA Infrastructure Java EE application."

• The next rectangle is labeled "UDDI Registry." An arrow starts at the "Composite Metadata Management" rectangle inside the "SOA Infrastructure Java EE application" and points to the "UDDI Registry" rectangle.

• The next rectangle is labeled "SOA Db (jdbc/SOADataSource)." An arrow starts at the "Service Engines (Mediator, BPEL, Workflow...)" rectangle inside the "SOA Infrastructure Java EE application"and points to the "SOA Db (jdbc/SOADataSource)" rectangle.

• The bottom rectangle is labeled "SOA MDS (jdbc/mds/MDS_LocalTxData Source)." An arrow starts at the "Composite Management (instantiation, targeting to BPEL, Mediator, etc....)" rectangle inside the "SOA Infrastructure Java EE application"and points to the "SOA MDS (jdbc/mds/MDS_LocalTxData Source)" rectangle.
