Help needed with jpedal java integration
I'm trying to use a Java library called jpedal (http://www.jpedal.org) in order to convert PDF files to images. The following works great from the commandline on my Mac: java -cp ./jpedal_trial.jar org/jpedal/examples/images/HiResThumbnailExtractor test.pdf jpg However I'm not sure how to invoke the same from CF. I added the jpedal trial jar to ColdFusion9/lib and then tried the following: cfset jpedal = createObject(java,org/jpedal/examples/images/HiResThumbnailExtractor) / and got the error: An exception occurred while instantiating a Java object. The class must not be an interface or an abstract class. Error: IllegalName: org/jpedal/examples/images/HiResThumbnailExtractor. I've spoken to the developer of jpedal, Mark Stephens, who told me that HiResThumbnailExtractor is not an interface or abstract class. As some of you may know, jpedal is already part of CF as Adobe have licensed the library for some of their PDF handling. I wondered if this was causing problems, but even after removing the original jpedal.jar from CF I got the same error. I was using CFPDF up until now to do the conversion but find the resulting images not good enough in terms of quality. For example even after specifying scale=100 in cfpdf, the resulting images are smaller than the original PDF. Any tips on how I can use the .jar file successfully would be much appreciated.

Re: Help needed with jpedal java integration
I've figured out the Java image part: cfset jpg = ImageNew(foo) cfimage action=write source=#jpg# destination=test.jpg overwrite=yes This works. But the fact that the two jars seem to conflict with one another throws a real spanner into the works... Is there any way I could separate them and have both present in CF? Regards, Stefan On 24 Jan 2011, at 13:30, Stefan Richter wrote: I've got two further questions. Now that I got the syntax right I can run cfset jpedal = createObject(java,org.jpedal.examples.images.HiResThumbnailExtractor) / cfset jpedal.init() cfset img = jpedal.getHiresPage(1, 1, '/Applications/MAMP/htdocs/testbed/test.pdf') and I get back a java.awt.image.BufferedImage What's the best/easiest way to now save this as a jpg to disk? Also the jpedal.jar that comes with CF seems to be interfering with the one I'd like to use. I can only get my example to work if I remove the CF version of the jar - but I think this will break other core CF features. Is there a way so that I can use both jars even though they contain some overlapping classes? Apparently the CF version is a custom version of jpedal and not the same as the one I downloaded from their site. Regards, Stefan On 24 Jan 2011, at 12:53, Stefan Richter wrote: DOH! Thanks Scott!
