You can open a file in the Source Editor by doing any of the following:
For a Java form (indicated by a
node),
the Open command opens the Design view for the form. If you want to view the
form's source, click the Source button in the Source Editor toolbar. Alternatively,
you can open a form's source directly by right-clicking the form's node and
choosing Edit.
For various deployment descriptor types, you can switch to the text editor by clicking the XML button in the Source Editor toolbar.
