I installed Spotfire nodes in KNIME and wanted to read data from Spotfire Information Links.
I have spotfire server url in the form: “https://spotfire.companyname.com/spotfire”
and information link url in the form: “/folder1/folder2/folder3/infolinkname”
But when i configure this information in the node and click Apply/OK, then it showed error: “failed to apply settings: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target”.
After this I removed the proxy configuration in KNIME and tried the above steps again. This time it logged “WARN KNIMEApplication$4 Potential deadlock in AWT Event Queue detected. Full thread dump will follow debug output.” and after 10 minutes an error dialog popped up with message “Invalid settings: connection timed out”.
I am neither able to read info links nor spotfire library data.
Has anyone faced this already? I am totally stuck with this issue. Any help will be appreciated.
It sounds like you might be missing a CA certificate in the AP keystore. Is that something the IT folks at your company can help with? If you are feeling adventurous, you could try the following:
I am able to proceed after adding the certificate in keystore, but now i get a message “401 unauthorized access” while trying to read an info link.
I investigated the issue further and found that the TIBCO Spotfire Nodes are not using the HTTP “Negotiate” authorization scheme. The spotfire server expects authorization through negotiate but I can’t find a way to use that scheme.
