Use tika with python, runtimeerror: unable to start tika server

Question

I am trying to use the tika package to Parse files. Tika is successfully installed, tika-server-1.18.jar runned with Code in cmd Java -jar tika-server-1.18.jar

My code in the Jupyter is:

import tika 
from tika import parser
parsed = parser.from_file('')

However, I receive below error:

2018-07-25 10:20:13,325 [MainThread ] [WARNI] Failed to see startup log message; retrying... 2018-07-25 10:20:18,329 [MainThread ] [WARNI] Failed to see startup log message; retrying... 2018-07-25 10:20:23,332 [MainThread ] [WARNI] Failed to see startup log message; retrying... 2018-07-25 10:20:28,340 [MainThread ] [ERROR] Tika startup log message not received after 3 tries. 2018-07-25 10:20:28,340 [MainThread ] [ERROR] Failed to receive startup confirmation from startServer.

RuntimeError: Unable to start Tika Server.

Any update to this question? I get the same error message. – Fsh

I gave up using TIKA Server, instead, I used TikaApp to solve the problem. "tika_client = TikaApp(file_jar = ''(where i have stored the tika app). It works. For parser I haven't found a solution, unfortunately. – Cockatrice

using TikaApp, tika_client.extract_all_content(path_to_file) returns an empty string – Nitid

Answer 1

According to Apache Tika's site, all new versions of the tika-server.jar will require Java 8.

24 April 2018: Apache Tika Release Apache Tika 1.18 has been released! This release includes bug fixes (e.g. extraction from grouped shapes in PPT), security fixes and upgrades to dependencies. PLEASE NOTE: The next versions will require Java 8. Please see the CHANGES.txt file for the full list of changes in the release and have a look at the download page for more information on how to obtain Apache Tika 1.18.

Current outdated docs for tika Python library claim that Java 7 is needed, but now Java 8 must be installed. This is because the current version of tika-server.jar is automatically downloaded at runtime if not found in your temp file.

After installing Java 8, my basic test code launched the server and worked without error.

It's not necessary to install java while working with Apachetika. – Lumberjack

I'm stuck in the same issue, I've posted a question too, could you please check this question. Seems like tika server is not starting, it returns Not Found 404. – Hendecasyllable

Answer 2

After you import Tika you need to initialize the Java Server

import tika
tika.initVM()
from tika import parser
parsed = parser.from_file('') //file name should be here

I tried the same way, I initialized it after import. It returns Not Founds 404. Please check this link. – Hendecasyllable

Answer 3

Download Java. If you already have a version of Java installed, try updating it to the latest version. The version that works for me is 1.18.

Answer 4

You have not passed an argument (specified a file) in your line:

parsed = parser.from_file('')

Give it a file to chew on e.g.,

parsed = parser.from_file('myfile.txt')

The server didn't start & presumably this no log warning gets triggered - see line 644 in the source at the Github

then another error message tells you it ain't going to play...

Answer 5

I faced similar issue. Tried all steps mentioned here, nothing helped. How I solved it:

1. checked the log file of tika and tika-server. For windows, you can find it inside C:/Users/your_user_name/AppData/Local/Temp/
2. Found that tika-server log had mentioned port already in use error.

check below log snippet -

INFO: Setting the server's publish address to be http://localhost:9998/
WARNING: FAILED SelectChannelConnector@localhost:9998: java.net.BindException: Address already in use: bind
java.net.BindException: Address already in use: bind

        at org.apache.tika.server.TikaServerCli.main(TikaServerCli.java:213)

3. This clearly indicated that another process is already running in same port. So I just needed to kill java process running on port 9998 (which I assumed might have been defunct)
4. Once I killed the process in task manager, I tried rerunning the python script, it worked correctly.
5. To cross check you can also run the tika-server.jar file present in same path - C:/Users/your_user_name/AppData/Local/Temp/ using below command and check if it fails or runs correctly: java -jar tika-server.jar

Hope this will be helpful to someone in future.

I got the same error and solved using steps below:

1. Check my tika server log file (usually its located at C:/Users/your_user_name/AppData/Local/Temp/)

   2023-04-02 08:06:47,277 [Thread-1 (pr] [ERROR] Unable to run java; is it installed? 2023-04-02 08:06:47,278 [Thread-1 (pr] [ERROR] Failed to receive startup confirmation from startServer.

2. It is suspected Java is not being installed. So check if Java is being installed using

   java -version

3. If it's not installed, you may download it here: https://www.java.com/en/download/.

4. If still error, try to start Tika server manually using:

   java -jar tika-server.jar

• Remember run it at where your jar file is located. Now it should work.

Answer 7

If your are using Ubuntu 20.01 (and 18.04) like me, the solution is to Install Oracle JDK 17. Do the following:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java17-installer

Type java -version on the terminal. You should see the following print-out:

java version "17.0.1" 2021-10-19 LTS`
Java(TM) SE Runtime Environment (build 17.0.1+12-LTS-39)`
Java HotSpot(TM) 64-Bit Server VM (build 17.0.1+12-LTS-39, mixed mode, sharing)

tika should then be able to extract text from your pdf in python.

parser.from_file(<your pdf file>)
