Hi Ramaraju Sagiraju​,

Which JDK version do you have?

And also share the steps you followed to setup the Java SDK? I hope you are using eclipse for this.

Thanks,

Ramaraju Sagiraju​, Seems that org.slf4j.helpers.MessageFormatter.arrayFormat is missing in your references.

Delete the old references. Readd the ThingWorx Jar files. Refresh your Project and it should work.

Or simply replace the jar files in the folder where it originally exist and refresh your project.

Do let me know if you face any issue.
