Internal Server Error (500)

[VitorRDias]

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]

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

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]

Installing version 333 worked for me!

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

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. pmE617.pdf

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) Tabula Version 1.2.1

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 :-)
