While trying to deploy the application server I keep getting the error "SEVERE [main] org.apache.tomcat.jdbc.pool.ConnectionPool.init Unable to create initial connections of pool.java.sql.SQLException: Unable to load class: com.microsoft.sqlserver.jdbc.SQLServerDriver from ClassLoader:java.net.URLClassLoader@254989ff;ClassLoader:ParallelWebappClassLoader context: ROOT"I have checked to make sure the jdbc driver is copied into the /tomcat/lib folder and also made sure its the correct driver needed. I have attached the logs. Thank you. Pega Platform ×Close popoverFacebookTwitterLinkedinEmail Copy Link Copied! Moderation Team has archived post This thread is closed to future replies.

Posted: 1 year agoKevinZheng_GCS PEGA replied to JeremyR4can you create an 'endorsed' directory under tomcat home and copy the jdbc jar there, restart pega again? Posted: 1 year agoJeremyR4 Segue Technologies Inc replied to JeremyR4Kevin, Restarting now will let you know result. Question, besides being in the /tomcat/lib directory, does the jdbc jar file need to be copied into any other directory? Thanks.

Logs have not changed and the web app has not come up. Any suggestion? Attached new log.
