Fix ISSN fetcher

[ThiloteE]

JabRef version

6.0-alpha

Operating system

Windows

Details on version and operating system

No response

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

How to reproduce:

Follow what is described in the forum: https://discourse.jabref.org/t/issn-fetch-noch-working/5346. In short: Add an ISSN to the entry and then fetch metadata.

Example ISSN:

1872-7980

Error:

Error occurred javax.net.ssl.SSLHandshakeException: (certificate_unknown) PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed

Additional notes:

ISSN fetching was introduced in #10178.

DOAJ has switched their API in June 2024. Maybe it broke ISSN fetching? Here are the docs to the current API (v.4.0.0): https://doaj.org/api/docs

In my system, fetching data using a DOI is also resulting in an error.

Which DOI did you provide?

@ThiloteE Was there any exception on the log? I am interested which server was used.

This happened.

This issue is about ISSN and not an issue about DOI.

@priyanshu16095 If you have an issue with DOI, please open a new issue and while videos are great, it is nice to provide error messages in text so that developers can use it to search for relevant code in their IDE. It is also nice being able select and then to copy and paste complicated text instead having to manually type it off a video screen.

@koppor yes, there was an exception in the logs. Here it is:
