Version: tesseract 3.02.02
Ubuntu 12.04, Eclipse Juno

I am trying to use ViewerDebugging.
Following the instructions in http://code.google.com/p/tesseract-ocr/wiki/ViewerDebugging

I installed javac
download piccolo-1.2.jar, piccolox-1.2.jar, and make ScrollView.jar

Then I use export to set the SCROLLVIEW_PATH, e.g. export SCROLLVIEW_PATH=/home/tesseract-ocr-3.02.02/java

edit svutil.cpp to remove the ">/dev/null 2>&1" from the cmd_template string.
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 see
Socket started on port 8461.

Now I am ready. I run:
tesseract phototest.tif test1 segdemo inter

Now the tesseract debugging window pops out.
In the terminal window, it says:
ScrollView: Waiting for server..

I can see nothing in the tesseract debugging window.

Can you post screenshot where is visible console with messages +  tesseract debugging window?

How can I solve the problem?

Did you tried unmodified source?

Thanks a lot in advance.

Actually yesterday I tried to post the same message on tesseract-dev, but not succeed.
If it happens to appear on tesseract-dev at some point of later time, sorry for that. I just do not want to wait for too long; eager to know the answer : )
If somebody tells me we need to wait for that long, I apologize for that and will wait later on.

Did you compile tesseract by yourself? If yes, did you use standard
compilation process(autotools)? What kind of options you used? Can you
send me config.log? Or did you used version from your distribution?
Do you have only one installation of tesseract in your system?

Me too have same problem.
The ScrollView works only once. Once I close it , it does not work anymore.

I follow the instruction in http://code.google.com/p/tesseract-ocr/wiki/Compiling
The version is 3.02.02

>> Do you have only one installation of tesseract in your system?

Before that I installed 3.01.

In the terminal, I confirmed that it is the new 3.02.02 working
$ tesseract --version
tesseract 3.02.02
 leptonica-1.69
  libgif 4.1.6 : libjpeg 8b : libpng 1.2.46 : libtiff 3.9.5 : zlib 1.2.3.4

Sorry I do not understand what option you referred to.

>> Can you send me config.log?

It is attached.  (It seems when I tried to attach it, there was error with the server)

Thanks for your help.

If I kill java manually from the processes, I can relaunch scrollview though.
