Hi @gnugent, I have a similar need and found out I was able to deploy the JChem Web Service Classic on the Knime apache server along side the sketcher. What you need to do is to unzip the content of the archive under <knime_installation_dir>/apache-tomcat-9.0.36/webapps. For the 20.19.1-10-b2303 version I deployed, this resulted in a webservices.war file and me_assets folder. You will also need to copy a valid ChemAxon license file under the .chemaxon directory of the home directory of the user who runs the Knime server. You can verify the installation is successful by visiting https://your_knime_server/sketcher.marvinJS/marvinJS/editorws.html and importing a chemical name or SMILES into the sketcher.
However, I still have a question for the Knime development team. The “Molecule String Input” node under Quickforms is hardcoded to use the webapps/sketcher.marvinJS/marvinJS/editor.html file as opposed to editorws.html. Can we introduce a parameter to let the user choose which file? Only editorws.html allows communicating with the JChem Web Services to translate between different chemical structure formats.
