Program crashes when trying to recognize an image about tesseract4java

[pvorb]

Thanks for the bug report. I'll have a look.

Did you use the batch recognition or recognition tab?

[pvorb]

Unfortunately I cannot reproduce the error. Does it also occur with other traineddata files or images? If not, can you send me the traineddata file?

This was just with the recognition tab. I tried with various images/traineddata. The program window just disappears without any dialogue. I later found the error logs in the directory where the jar file is.

I will test again later and report.

Seems to be some conflict with libtesseract.
I updated java.
I also tried using a batch file such as follows:

set TESSDATA_PREFIX=C:\Users\User\Documents\shree
echo %TESSDATA_PREFIX%
start javaw -Xms128m -Xmx1024m -jar tesseract4java-0.1.0-windows-x86.jar

The program used to start and work for a while before crashing, I was able to open box files and view them by character. After one of the crashes, now program does not start at all - just creates error log ..

The program window just disappears without any dialogue.

Unfortunately it is not easy to prevent the JVM from crashing when there's such an EXCEPTION_ACCESS_VIOLATION. The only way would be to run Tesseract from another JVM process, which would make things more complex -- but probably that's the way to go.

Thanks for the new error log. This seems to be a similar but different issue than your problem yesterday. I can see from the log that the error occurred when running batch recognition. Probably you selected a traineddata file that causes Tesseract (or at least the bundled dll) to crash.

Yesterday the error occurred directly in the recognition tab, so it is a different problem, but both should be solved.

If you can't start the software any more, you can delete the Windows Registry key HKEY_CURRENT_USER\Software\JavaSoft\Prefs\de\vorb\tesseract\gui\model\training_file. Alternatively, you can change it to another traineddata file (try "eng").

It would be great if you could send me the traineddata file, so I can reproduce and fix the error.

[Shreeshrii]

I deleted the Windows registry entry and now it is NOT crashing. You may close the issue.

Problem was coming with the eng.traineddata also but NOT anymore - so it was related to conflict because of pointing to an external directory for tesseract executable.

Qn. Is eng.traineddata included with program?

[pvorb]

No, it's not included with the program. The program has no bundled traineddata files.
