Publishing webhelp with a JSON file

[NilsG]

Hello
I'm trying to publish a webhelp with a JSON file in one of the ditamaps. I'm using the com.oxygenxml.json.dita plugin to automatically create a DITA file from the JSON file. For context: the JSON file contains software strings that I'd like to use in uicontrol elements.
I'm using Oxygen 26.1 build 2024042206 with the built-in DITA-OT on Windows 11.
When running a transformation scenario (HTML5 and Webhelp Responsive), I get the following error:

C:\DevTools\Oxygen XML Editor 26\frameworks\dita\DITA-OT\plugins\org.dita.base\build_preprocess.xml:91: java.lang.NoSuchMethodError: 'org.apache.xml.resolver.tools.CatalogResolver org.dita.dost.util.CatalogUtils.getCatalogResolver()'

Any ideas about what might be wrong?
Thanks!!

Hi Nils,
The plugin relies on some code in the DITA OT main library. I just tested installing it in an Oxygen 26.1 DITA OT and it seems to work for me.
Is it possible that you have changed the folder "C:\DevTools\Oxygen XML Editor 26\frameworks\dita\DITA-OT\" from your side? Maybe place there an older DITA OT distribution? If so, the "dita-json" project is open source to maybe you can adapt it to work with your specific DITA OT version.

Radu

Thank you, Radu!
I don't remember doing anything other than installing a few plugins.
I reinstalled Oxygen (this time under C:\program files) but to no avail. I still get the Error: java.lang.NoSuchMethodError: 'org.apache.xml.resolver.tools.CatalogResolver org.dita.dost.util.CatalogUtils.getCatalogResolver()'.
I tried with the sample ditamap file from the plugin, while I had the sample.xpr project loaded.
A second experiment with a DITA-OT v.3.6.1 and Oxygen 26.1 is working.
I can also run it using Oxygen 24.1 with the built-in DITA-OT.

Any tips or help is much appreciated!
Best regards
Nils

Hi Nils,
Focusing on making Oxygen 26.1 and its bundled DITA OT 4.1.2 work with the plugin, after you install the plugin in the "OXYGEN_INSTALL_DIR/frameworks/dita/DITA-OT/plugins" and run the integrator, if you run the HTML5 publishing and it fails there should be a "DITA OT" console tab view at the bottom of Oxygen. Could you copy all the contents from that console tab view to a file and email it to us (support@oxygenxml.com)? Maybe somehow the entire logging received from the DITA OT will help me.
Anyway, I'm glad someone is using this open source plugin I created, hopefully it's useful to you.

Regards,
Radu
