[Dspace-devel] [DuraSpace JIRA] (DS-1607) detect when ImageIO JARs are not present (when using XPDF) and print a meaningful error

[DuraSpace JIRA]

Ivan Masár created DS-1607 detect when ImageIO JARs are not present (when using XPDF) and print a meaningful error Issue Type: Improvement Affects Versions: 3.2 Assignee: Unassigned Created: 28/Jul/13 11:16 PM Description: The problem is described by this thread: http://dspace.2283337.n4.nabble.com/XPDF-Thumbnail-Creation-td4665862.html The user got a generic error (java.io.IOException: Unknown failure while transforming file to preview: no image produced. ). It was unclear what went wrong. In order to better inform the user of what he did wrong, the error message should say "Couldn't filter file %s because XPDF support was requested, but ImageIO JARs were not found. Please, copy jai_core-1.1.2_01.jar and jai_imageio-1.0_01.jar to [dspace]/lib". The error message should be triggered when both "source = ImageIO.read(outf);" [1] returns null and ImageIO is not available.
