Unable to launch...

I cleared the Java cache, downloaded the JNLP file fresh, and got an InvocationTargetException trying to launch.

The launch file:

When I try to run the manual install, I get the same thing:

Sorry, I should have mentioned I'm on OSX. It's possible that Apple only supplies JAI 1.1.2, since I found jai_core.jar under /System/Library/Java/Extensions, and the META-INF/MANIFEST.MF file from there shows version 1.1.2.

I think there is a 1.1.3 non-native pure Java floating around on jai.dev.java.net, but they seem to having one of their regular website outages right now :/

Here's the super-secret location of the 1.1.3 binaries:

http://download.java.net/media/jai/buil ... ase/1_1_3/

And for the jai-imageio:

JAI ImageIO 1.1:
http://download.java.net/media/jai-imag ... lease/1.1/

Let me know if the 1.1.3 version helps.. I had to tweak something for the jp2 downloads to work around a bug.. but that might have exposed another bug...

I checked with another person who's running OSX, and he's having problems too. I've checked in a fix that may help the issue. Give it another try.

Grr. I tried 1.1b, same problem.

I downloaded the platform-independent version of JAI 1.1.3, and ran BSW:

Code: Select all

$ java -classpath BookScanWizard.jar:../../jai-1_1_3/lib/jai_core.jar:../../jai-1_1_3/lib/jai_codec.jar -Xmx1024M  net.sourceforge.bookscanwizard.BSW

So no luck there. I couldn't find a platform-independent version of ImageIO. If only java.net were alive, I could try downloading the source and compiling...

In any case, you know my problem with JAI. It looks like you're trying to zip some files. If you're creating a JAI operation to zip files, maybe instead you can use java.util.zip?

Correction: this is because of ImageIO, which I apparently don't have (and can't get).

OK, there appears to be some hope. Doing an immense amount of Googling, I got the impression that you could actually download any of the ImageIO packages (linux, windows, or sun), unzip it, find the jai_imageio.jar file, and include that in the classpath. Apparently ImageIO will fall back to a platform-independent version of JPEG2000 if it can't find a native version.

So I tried this:

Code: Select all

$ java -classpath BookScanWizard.jar:../../jai-1_1_3/lib/jai_core.jar:../../jai-1_1_3/lib/jai_codec.jar:../../jai_imageio.jar -Xmx1024M  net.sourceforge.bookscanwizard.BSW

CreateArchiveZip Could not find proper writer.  Using: com.sun.media.imageioimpl.plugins.jpeg2000.J2KImageWriter
But BSW did start up! I'll try to run through a book and see what happens.

Cool..I'm glad you got that working.

Here's the source code for jai-imagio (which you probably dont' need anymore):
http://java.net/projects/jai-imageio-core/sources

But the situation with java.net is really a mess.

Yeah... working JAI in BSW has been a challenge. I keep running into bugs with jai and jai-images. For the most part it is possible to work around the problems I'm finding, but it is time consuming. I do think its the best thing out there for image manipulation in java (as sad as that is).

I'm not using jai to create a zip.. I'm using it to write out the image to a stream that goes to a zip file. Unfortunately, where it is failing is just finding a jpeg2000 writer. I'm guessing that the version that is getting installed on OSX doesn't have that writer.

I'm thinking I might have to release a java-only version of BSW for OSX that has a self-contained jai and jai-images.

I'll take a look tonight and see if I can't figure some workaround.

Rob,

Was there an older version of jai_imageio.jar installed somewhere else?

You can try using the -verbose:class option when starting the app (don't list it on the classpath).

Its really weird. I verified that the missing files are in the webstart imageio-jar file, so I'm not sure why it is failing to find it.

Ok.. I think I figured it out.. Evidently OSX requires ImageIO.scanForPlugins() to work right.

Write once, run anywhere... yeah.

Anyways, I've updated the code to 1.1c to fix this issue.

Edit: Just heard from a mac user that it indeed fixed the problem.

I have an idea to bypass that thing that looks like it came out of my nose during a particularly bad cold -- what's it called? Oh yeah, the JAI :mrgreen: -- completely while making the program even more portable and possibly faster. Sounds too good to be true? It's possible, which is why I want to fiddle around with the BSW source a little more before claiming victory.
