When you delete an XML registry that is associated with a WebLogic
Server instance, the XML parser and transformer used to parse and
transform XML documents reverts back to the default. You must associate
a new XML registry with WebLogic Server if you want to change these
defaults, configure external entity resolution, or associate a parser
with a particular document type.
To delete an XML registry:
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the left pane,
expand Services and select XML Registries.
In the XML Registries table, select the checkbox next to
the XML registry you want to delete.
Click Yes to confirm the deletion.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
