Jakarta EE 9 is still in development - hence why the Tomcat 10 release is a Milestone. It isn't a given that libraries written to the Java EE 8 APIs will be updated for the Jakarta EE 9. If Jakarta EE 9 versions of libraries are not available then there are a couple of options: 1. Convert an existing JAR written for Java EE 8 to Jakarta EE 9 using the migration tool the Tomcat team has written for that purpose. 2. Stick with Tomcat 9. We will be producing versions of Tomcat (9.10.x, 9.11.x etc) that align with Tomcat 10, Tomcat 11, etc. apart from the fact they will continue to support the Java EE 8 APIs so there is an upgrade path for newer Tomcat functionality while retaining Java EE 8 compatibility, Mark > > -----Original Message----- > From: Mark Thomas <ma...@apache.org> > Sent: Monday, March 2, 2020 9:34 AM > To: users@tomcat.apache.org > Subject: Re: Tomcat 10.0.0-M1 can't get JSP taglib to work > > On 02/03/2020 14:16, e...@wolfecomputerservices.com wrote: >> I have tried everything in the multiple threads on this site (non of >> them were for Tomcat 10 and non of the solved problem.
