ViewerDebugging error on Windows

[Matteo Brisinello]

Hi,

I use Tesseract 3.05.00dev on Windows 7. I followed all the steps from https://github.com/tesseract-ocr/tesseract/wiki/ViewerDebugging :

1) Installed Java runtime,

2) Downloaded picoolo2d-core-3.0.jar and piccolo2d-extras-3.0.jar and put them in the C:\Tesseract-OCR\java where SrcollView.jar is located,

3) Set the SCROLLVIEW_PATH to C:\Tesseract-OCR\java,

4) Downloaded piccolo-1.2.jar and piccolox-1.2.jar from http://www.java2s.com/Code/Jar/p/Downloadpiccolo12jar.htm and also put them in the C:\Tesseract-OCR\java folder,

5) java is in the path.

I downloaded Tesseract from https://github.com/UB-Mannheim/tesseract/wiki (the .exe file).

When I run java -Xms512m -Xmx1024m -Djava.library.path=%SCROLLVIEW_PATH% -cp %SCROLLVIEW_PATH%/ScrollView.jar;%SCROLLVIEW_PATH%/piccolo-1.2.jar;%SCROLLVIEW_PATH%/piccolox-1.2.jar com.google.scrollview.ScrollView,

I get the message Socket started on port 8461. When I run tesseract phototest.tif test1 segdemo inter in a different cmd, I get this message in the first window:

Client connected

        at java.lang.ClassLoader.loadClass(Unknown Source)

        ... 3 more

and nothing happens.

Does anyone know what is the problem?

I solved the problem by downloading files from http://rdaemons.blogspot.hr/2012/06/tesseract-ocr-interactive-debugging.html provided by Dmitri Silaev.

The download link is http://www.4shared.com/zip/FnP8RSu0/tess_debug_3_02.html.

I copied piccolo-1.2.jar, piccolox-1.2.jar and ScrollView.jar from the downloaded package to C:\Tesseract-OCR\java.
