Oracle WebLogic Server 14.1.1/14.1.2 and JDK 17 clients using connection to JMS queue

in Oracle Weblogic Server (MOSC) 2 commentsAnswered ✓

Our Oracle WebLogic server is currently running on 14.1.1 version and we are using t3 (t3s) connection to JMS queues.

Our client application must be upgraded to JDK 17 as obligatory update of underlying framework.

 When we tried to use JDK 17, our JMS connections stopped working with an error 

"Timed out while attempting to establish connection to :t3://host:port [Root exception is java.io.IOException: Timed out while attempting to establish connection to :t3://host:port]"

The error is explained in the article: 

The article provides solution with explanations :" JDK 17 is not supported for clients that uses wlthint3client jar. Only Oracle JDK versions 8 and 11 are supported". In this terms, our application cannot be upgraded to JDK 17.

Howdy, Stranger!
