I am getting following error when configuring Binary Objects to Files node:
ERROR Binary Objects to Files 6:0:0:3890 Configure failed (NoClassDefFoundError): org/knime/filehandling/core/data/location/cell/SimpleFSLocationCellFactory
The input table contains one column with binary object (Model). I havetried different folder options such as Temp folder, Mountpoint relative, Workflow relative, Local file system.
Could someone please help me to fix this problem?
which version of KNIME AP do you have?
The Binary Objects to Files is trying to access a class that was introduced with 4.3.2 (SimpleFSLocationCellFactory), so if you didn’t update to 4.3.2, yet, this might solve the issue.
Thank you for your reply. I am using 4.3.1 and I cannot update the version yet. It might take some time before we can move to next version. Is there any work around for this issue?
it took me a while to reproduce the issue and then even more time to find a solution
I’d still recommend to update to 4.3.2 since the difference to 4.3.1 are “only” bugfixes and not a lot of new features.
Anyway, I might have found a solution that does not require an update (at least not to 4.3.2). It consists of the following two steps:
- Replace the default update site https://update.knime.org/analytics-platform/4.3/ with https://update.knime.org/analytics-platform/4.3/4.3.1 (File->Preferences->Install/Update->Available Software Sites)
- Install the KNIME Basic File System Connectors. If you already have them installed, you’ll have to uninstall them first (Help->About KNIME Analytics Platform->Installation Details)
Please let me know if this helps or if you need any help.
I am getting following error when added https://update.knime.org/analytics-platform/4.3/4.3.1 into update sites
Unable to read repository at https://update.knime.org/analytics-platform/4.3/4.3.1/content.xml.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Can you try the following update site instead:
(the only difference is .com instead of .org but they should work both )
As a last resort, you can also download the zipped update site from Previous Versions | KNIME and incorporate it as local update site.
Update using zipped file worked!! And there is no error anymore
