Properties, Problems, and Debug Views
Properties View
All operations and services have editable properties. When a resource is in focus, their respective properties are displayed in the Properties view.
Problems View
The Problems view displays errors, warnings, and information related to the validation of your BPEL process. You can correct any invalid activities before you test your process.
To filter elements by different severity options, click 
on the Problems tab to display the Filters dialog box.
Debug View
The Debug view has two tabs - the Breakpoints tab which shows you the breakpoints you have set and the Variables tab which shows you the value of the variables as you step through the process. On this tab you can see the value of the variables changing as you walk through the process and determine if the values are what you expect. Click 
on the toolbar to enter Debug mode.
