I am getting this error when I try to run my report.
java.lang.RuntimeException: Could not connect via JDBC: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager MBean: oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager: oracle.ucp.UniversalConnectionPoolException: Universal Connection Pool already exists in the Universal Connection Pool Manager. Universal Connection Pool cannot be added to the Universal Connection Pool Manager
The report runs from the studio properly.
but when deployed on tomcat it does not work.
when I enabled debug it started showing this error.
Please advise.
the URL I am using is "http://localhost:8081/jri/report?_repName=RSPM_JC_leaving_certificate"
the file is in reports folder.
