1. In Integration Server Administrator, click Settings > Extended > Edit Extended Settings.
2. In the Extended Settings editor, type the following:
watt.ejbadapter.fatalErrors=<error_1,error_2,...
error_n>
For example:

Note:
The parameter name is case sensitive.
3. Click Save Changes. A key for the new property appears in the Extended Settings list.
