Tilman Hausherr commented on TIKA-3319:
---------------------------------------
re tika-server / tika python I don't know, you put so many problems in a single
issue. My answers are about the NPE and the warnings.
> Caused by: java.lang.NullPointerException (and more!)

> Key: TIKA-3319
> URL: https://issues.apache.org/jira/browse/TIKA-3319
> Project: Tika
> Issue Type: Bug
> Components: general
> Affects Versions: 1.24.1
> Environment: Windows 10
> Tika 1.24.1.jar
> Tika 1.24 python module
> python 3.9.2
> tesseract-ocr-w64-setup-v5.0.0-alpha.20201127
> (anything else that may be relevant?)
> Reporter: Richard Kraus
> Priority: Major
>
> So...in sum
> 1) it somehow doesn't "point" to a parser? (but it kinda does...)
> 2) it says that I'm excluding tesseract from tika....I don't know how this
> happened to begin with
> 3) and now...urllib in python by using the tika package suddenly can't
> figure out tika exists...
> Please assist. Thank you in advance.
> 01 Tika-1.24.1.jar and 1.24 python module have been running well for months
> on my machine.
> 02 Then I get tesseract and a couple other things to integrate with it.
> 03 Then I upgrade python from 3.8.2 to 3.9.2
> 04 So I have always set the windows 10 $env: variable to something like
> TIKA_SERVER_JAR="<yourpath>/tika-server.jar"
> 05 Then I run the tika python module. I get this urllib problem....
> urllib.error.URLError: <urlopen error unknown url type: c>
> 06 Supposedly this is fixed by setting the $env: variable to something
> like...
> TIKA_SERVER_JAR="file:///<yourpath>/tika-server.jar"
> 07 So I do this and mess around with it; no dice.
> 08 So then I'm trying to run Tika on powershell right?
> java -jar "C:\PATH\TO\tika-app-1.24.1.jar" --gui
> brings up the gui but it gives me these "Warnings" now...
