SDF Reader failed: Configure failed (NoClassDefFoundError)

[jwang_knime]

I am new. I want to read a SDF file. I installed http://update.knime.com/partner/4.0, so I got LigandScout installed. I drag SDF Reader to there and I entered things in Configuration. But the SDF Reader has a red cross and saying:
ERROR SDF Reader 3:1 Configure failed (IllegalAccessError): class com.inteligand.ilib.config.o (in unnamed module @0x700b7a49) cannot access class sun.font.FontManagerFactory (in module java.desktop) because module java.desktop does not export sun.font to unnamed module @0x700b7a49
ERROR SDF Reader 3:1 Configure failed (NoClassDefFoundError): Could not initialize class com.inteligand.ilib.util.a.r$b

Hello @jwang_knime,

and welcome to KNIME Community!

If you are on the latest KNIME version (5.4.0) then it won’t work as extension containing this node is still not available according to documentation:
https://docs.knime.com/latest/analytics_platform_installation_guide/index.html?pk_vid=7fad19ef566bc5bc1738052849f3ae39#community-extensions-540

Br,

Thanks. Then, how do I find an older version that works?

Why don’t you use the SDF Reader that is part of the official Chemistry extension?

Thanks, Thor. You mean that the SDF Reader under Chemistry extension is a different program from that under LigandScout and it is free. That’s great news! I have already changed to the old version 5.2.0 and it is working. I will update later.
