from the error message I assume that you are using Remedy API 6.3.
You will need the following files:
If they are not part of the Java or C API, please check the Remedy Server Installer for the Email option (my administrator from which I obtained the API found them there). Please restart the IS after adding the files to the mentioned locations.
I recommend that you install RMDY_6-0_Fix2. Otherwise you will have difficulties while creating or updating entries in your forms (especially fields which have a ‘.’ in their names).
Please add your experiences with the Adapter to the following Thread in this forum: http://advantage.webmethods.com/article/?id=1610634830
