Jabref: Jabref tries to establish an unsecure connection to Medline

Created on 3 Nov 2016  Â·  19Comments  Â·  Source: JabRef/jabref

Jabref tries to establish an unsecure connection to Medline over http instead of https. I noticed this is a temporary problem (4th November) and the change will be made permanent by NCBI at the 9th November. Please change the URL in your code from http to https.

https://www.ncbi.nlm.nih.gov/home/bulletins/https-tests.shtml

JabRef version 2.10 on Ubuntu 16.10

Steps to reproduce:

  1. Open JabRef
  2. Press F5
  3. Type in a Pubmed ID
  4. Press Fetch

I just tried the packaged new 3.6+ds-1 (uploaded half a day ago) on Debian/unstable, and I can't find any SSL errors.

You have to use the latest master from http://builds.jabref.org

There you can download the installer

Tried ./gradlew getdeps and ./gradlew -Pdev=true -Pinstall4jDir="install4j6" check release --stacktrace as well, similar SSL error.

Hi,

you should just run ./gradlew build that's enough,

Your error seems to be a more general SSL problem with your computer/OS:
Which OS and which JAVA version are you usin? (You should use the latest
Oracle java 8 sdk)

Ubuntu 16.10 x64, Java OpenJDK 8

To be honest, this was almost unbearable. I had to manually download the NCBI certificate with Firefox from the site over the lockpad icon and do the following steps:

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
keytool -list -keystore "$JAVA_HOME/jre/lib/security/cacerts"
sudo keytool -import -noprompt -trustcacerts -alias ncbi -file ~/Downloads/NCBI.crt -keystore "$JAVA_HOME/jre/lib/security/cacerts" -storepass "changeit"

Then I could run the jar file from the daily autobuilds and use the Web Search successfully. So this case is closed I guess?

Compiling from source requires a different certificate which I haven't found yet.

Unrelated:
Whoever is packaging this for Ubuntu might consider bringing this into ubuntu-updates along with the necessary certificates. For a casual user this is unfixable. Why is java using its own keystore anyway.

Zomtir picture Zomtir on 4 Nov 2016

@Zomtir Thanks for the feedback! Glad you found it working. That complicated stuff is really hard.
I just searched and there seems to be some extra certificates packages in ubuntu/debian:
https://installion.co.uk/ubuntu/yakkety/main/c/ca-certificates-java/install/index.html

Could you please try again, if this helps.

Unfortunately we currently do not have a newer jabref package for ubuntu, nor do we maintain it.
If you are interested, or know someone who would do it, feel free to contact us.

Siedlerchr picture Siedlerchr on 4 Nov 2016

ca-certificates-java were already installed. I guess they are a dependency of OpenJDK.

The certificates from these pages were not helping at all:

This one seemed to have an effect (took longer to fail and different error), but there's still more certificates missing beside this one:

Thanks for the offer, I'll come back at you if I'm able and allowed to package for Ubuntu, which both are out of reach atm unfortunately.

Zomtir picture Zomtir on 5 Nov 2016

The ubuntu package also provides only version 2.10.

At least we should download all the required certificates and write something in the help. A similar problem (for google.de and jabref.de for updates) was reported previously.

tobiasdiez picture tobiasdiez on 5 Nov 2016

I have created a follow up issue #2235
@Zomtir You are using openjdk8, could you please test with oraclejdk8?

For ubuntut here you find a repo/instructions:

No proxy, no VPN.

Installing the certs ain't the problem, I'm having more troubles to find out which connections are rejected. The logs only print the trace, but not the URL triggering it.

Zomtir picture Zomtir on 5 Nov 2016

This problem with SSL seems not to be limited to single certs but Being a more general one. Neither medline, nor JabRef.org, nor gradle.org certs are accepted by your machine...

Perhaps reinstalling the ca-certificates-java helps as indicated here http://stackoverflow.com/questions/29584328/gradlew-bat-and-gradlew-sslhandshakeexception#answer-30924895 ?

matthiasgeiger picture matthiasgeiger on 5 Nov 2016

This reminds me, that I had problems with the SSL handshake also for the MathSciNet fetcher. Thus there is a ugly hack implemented, which ignores the certificates, see https://github.com/JabRef/jabref/blob/7d8427470a98678018e11366db458397360bc77f/src/main/java/net/sf/jabref/logic/importer/fetcher/zbMATH.java#L85. We could install this hack globally without a problem.

tobiasdiez picture tobiasdiez on 5 Nov 2016

Reinstalling ca-certificates-java had no effect.

Can someone reproduce the build error on Ubuntu? So I can be sure that it's not only on my end.

Zomtir picture Zomtir on 5 Nov 2016

I recently tried this to reproduce in my Ubuntu 16.04 VM and I could not reproduce this issue.
So, this issue seems to be only on your system. Thererfore I would close this issue, as we can't do anyhting about it atm.

Siedlerchr picture Siedlerchr on 9 Dec 2016

I just tried the packaged new 3.6+ds-1 (uploaded half a day ago) on Debian/unstable, and I can't find any SSL errors.

I gonna test again with 17.04 and see if it's gone. By the looks of it, my own setup is messed up, so really nothing you can do about. Thanks for help nontheless, it's in a usable state with the jar file for now.

Thank you Zomtir!!

After many failed tries, your suggestion (manually download NCBI certificate + import it with keytool) solved the problem for me: Ubuntu 16.04 x64, Java OpenJDK 8
