Internal Server Error (500) by VitorRDias · Pull Request #1174 · tabulapdf/tabula

VitorRDias · 2022-05-03T15:19:46Z

I tried to open Tabula in my work notebook and it showed the following Internal Server Error (500):

How to fix that error?

Same happened here. It was solved by updating from Java 8u331 to Java 8u333.

RichardMisencik · 2022-05-04T08:41:39Z

@rua4 java control panel is reporting 331 to be the latest version, how to update please?

mtovmassian · 2022-05-04T13:06:09Z

On a Windows machine I bypassed the Java Control Panel by manually installing the Java 8u333 via https://www.java.com/en/download/manual.jsp

You can manually install the newer version as suggested by @mtovmassian or downgrade to lower version (e.g. 8u321, 8u311 etc).

VitorRDias · 2022-05-05T18:21:37Z

Installing version 333 worked for me!

aylmao22 · 2022-06-10T04:03:13Z

Still having same internal server issue with 333 and 331, any ideas?

MattiFish · 2022-07-26T07:09:35Z

Still having the 500 error when using Tabulapdf on mac (Cataline 10.15.7). This is occurring only on specific tables I am trying to convert. I am seeing certain lines excluded from the OCR conversion (see images below). When I focus the OCR on the specific area excluded, I get the 500 error.

I have downloaded the latest Java (v8u341) but I am not sure if it is being used by Tabula (I think I read that the mac version comes with its own java version so I think this might be the main problem).

I have not been able to replicate this on the windows 10 version but I was using a smaller dataset. Java was up to date as far as I could tell (v341).

Hope I included all relevant info, new to Github. Great tool btw!

Edit #1: Similar thing happening on windows 10 (build: 19044.1826) and java (8u341). Firefox browser if that makes a difference. Interestingly only some areas get processed fine. I am using invoices and some come out perfect, others with these errors, even when it is in same format.

Repeats of:

Jul 31, 2022 7:38:16 PM org.apache.pdfbox.pdmodel.font.PDType0Font toUnicode
WARNING: No Unicode mapping for CID+41 (41) in font NVFQUS+Arial
Jul 31, 2022 7:38:16 PM org.apache.pdfbox.pdmodel.font.PDType0Font toUnicode
WARNING: No Unicode mapping for CID+32 (32) in font TSSNBB+LucidaConsole

...coming up in the Tabula console.

Successful in replicating this error (500) in windows.

Edit #2:

Using Preview (on Mac) yields incomplete characters (I am not sure exactly how to extract the exact representation of it):

1N􏰃AAN 20/0A/2022 20A155 Eum20 2􏰂/T5􏰃07N OAOALO 􏰀A 􏰂52011AN1A 1

Which should read as:

198669 20/06/2022 206155 eum20 24/F58079 BABALO V6 4520116916 1

Tabula extracts the table below this without issue.

Edit #3: Found an interesting example of this problem in my dataset. A PDF invoice has two pages, one table is repeated across both pages. The info from the table on page 2 is extracted correctly, the first table throws the 500 error when focusing on the data in the table. Example of PDF attached.

I tried to install Java 8u333, but does not work

I am also getting a similar error, strange as was working the other day:

I'm getting a 500 error too, looks like Java updated today, 4/13/2023.

JAVA Version 8 update 361 (build 1.8.0_361-b09)

Working here with Java 8 u371.
I recommend uninstalling older versions of Java and leaving only the latest.
Also extract and run the program in a folder that does not recquire privileges (eg. Downloads, Desktop etc)

It happened even to me on Ubuntu 22.04.

It was about the server not working. I needed to downgrade to Java8

  0            /usr/lib/jvm/java-19-openjdk-amd64/bin/java      1911      auto mode
  1            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1111      manual mode
* 2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode

Selected *2 (java-8), then just run the command
java -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -jar tabula.jar

Little bit struggling but fixed in the end :-)

You're seeing this error because you use JRuby::Rack::ErrorApp::ShowStatus.

Maybe you want to try adding "... --add-opens=java.base/java.util.zip=ALL-UNNAMED ..." when running it. It helped for me.

micahchoo · 2024-12-07T16:40:46Z

For Ubuntu 24.04 this command worked for the below error

java --add-opens java.base/java.util.zip=ALL-UNNAMED -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -jar tabula.jar

to use newer java

  java -Dfile.encoding=utf-8 -Xms256M -Xmx1024M -Dwarbler.port=9999 -jar tabula.jar

(You can enable the old "automatically open browser" behavior by using
the -Dtabula.openBrowser=true option.)

Starting the server with a working preview of the PDF using Java 21 requires the --add-opens and --add-exports options.

java --add-opens java.base/java.util.zip=ALL-UNNAMED --add-exports java.desktop/sun.java2d=ALL-UNNAMED -jar tabula.jar
