Binary Objects to Files not working

Hi,

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

Screen shots:


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?

Regards,
Nithin

Hello @nithinth7,

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.

Best,
Adrian

Hi @nemad

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?

Hello @nithinth7,

it took me a while to reproduce the issue and then even more time to find a solution :smiley:
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:

  1. 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)
  2. 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.

Cheers,
Adrian

Hi Adrian,

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

Uff bummer.
Can you try the following update site instead:
https://update.knime.com/analytics-platform/4.3/4.3.1
(the only difference is .com instead of .org but they should work both :frowning: )
As a last resort, you can also download the zipped update site from Previous Versions | KNIME and incorporate it as local update site.

Best,
Adrian
