We are using a jsp page in request form to fetch certain values from application database. The jsp was working fine but suddenly we have started getting Unable to get manager connections error.


ERROR: java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/jdbc/dematrix
08/19/2020 13:03:03.577 ERROR (default task-48) [SystemErr] java.lang.NullPointerException


Connection details have been defined in aveksa-standalone.xml and pool size is also defined at 500 but still we are getting the above error.


Kindly help.
