LiveCycle ES2: repeated ServiceNotFoundException in the server log


 If you are running LiveCycle ES2 you may notice the following exception message in the server log:

2011-04-20 18:03:54,291 INFO [com.adobe.idp.dsc.workmanager.impl.ExecutableUnitWrapper] No class loader found for service: Events. Cause: com.adobe.idp.dsc.registry.ServiceNotFoundException: Service: Events not found.


 This message on its own is benign, i.e. it does not indicate a problem with the LiveCycle server, and can therefore be ignored.  It is an INFO level message, and not an ERROR or WARN level message which indicates the priority.

If the message does occur as an ERROR or WARN level message with other exceptions, then this should not be ignored and you should analyse the other exceptions to find the root cause of the issue.

Additional information

The work manager in LiveCycle was looking for a service called “Events” in order to get its class loader to serialize/de-serialize objects (ExecutableUnit) whose definition is in that service.  When it couldn’t find the class loader for the Events service, LiveCycle will continue to use the default class loader.

LiveCycle Designer: XFAImageService error importing a Photoshop JPG into an XFA form


 If you are trying to import JPEG images produced with Adobe Photoshop into an XFA-based form in LiveCycle Designer, then you may notice the following error in the warning palette:

Error reading JPeg file : JFIF supports only 1 and 3 component streams. 

XFAImageService: Image cannot be resolved for node: StaticImage1


 1. Use Photoshop version 6 or less to produce the JPEG images

2. Re-save the JPEG images from Photoshop using the “Save for Web…” option in the File menu

3. Re-save the JPEG images using Paint in windows, or any other image editing tool which does not add the preview information described below

Additional information

 This error occurs when Photoshop 7 or greater was used to create the JPEG images.  This is due to a change in the JPEG format produced with Photoshop 7 and greater, which now includes a thumbnail preview of the JPEG image included in the JPEG profile.  Such profile information does conform to the JPEG/JFIF specification, however some applications like web browsers, or in this case, LiveCycle Designer cannot handle the preview data correctly.
