After you create a ruleset, you must configure it.
To configure a ruleset:
Open an existing ruleset or create a new one.
See "Creating Rulesets" for more information.
Click Edit Code.
An empty DRL file opens.
Note:
Oracle recommends that you download the JBoss text editor and configure Design Studio to use the editor of the DRL file. The JBoss text editor can catch syntax errors that can be corrected as you write the ruleset, rather than waiting to catch the errors at compilation.Write the ruleset.
See UIM Developer's Guide for detailed information about writing a ruleset.
From the File menu select Save, then close the DRL file.
From the File select Save again to save the ruleset.
