Please be sure you’ve read the docs and API specs before asking for help. Also, please be sure you’ve searched the forum for your answer before you create a new topic.
Please consider addressing the following when creating your topic:
What have you tried?
What errors did you face (share screenshots)?
Share the details of your efforts (code / search query, workflow json etc.)?
What is the result you are getting and what were you expecting?
Can you provide more details on what it is your trying to do? Just based on the error logs it is hard to tell exactly what you are trying to do. Also include the command your running.
Could you please provide the full stack trace? Also, can you confirm which MySQL JDBC jar is present in ../WEB-INF/lib (if any)? Additionally, could you share the connection pool settings from the iiq.prop file?
