Open this view by selecting

Windows > Show Views > Relationship View

.

This view shows you a graphical representation of dependencies and references of BPEL, WSDL, XSD, and other artifacts in relation to the file open in the editor. Using this view, you can track the location of WSDL and XSD imports and other artifacts that are in the workspace.

For example, if a BPEL file is open, you'll see a relationship diagram of the files that the BPEL file depends on, such as WSDL, XSD, and HTML. You can select another file to see its dependencies and references.

You can toggle the view by using the toolbar buttons,

Show Dependencies

and

Show References

.
