Comment 4 Herman Viaene 2026-05-14 14:21:22 CEST
MGA9-64 server Plasma Wayland on Compaq H000SB
No installation issues.
Ref bug 34231 for testing.
Copied following lines to /etc/tomcat/tomcat-users.xml from /etc/tomcat/tomcat-users.xml.rpmsave before the end line:
<user name="tester9" password="tester" roles="manager-gui" />
I had sample.war from previous updates.

Then I could connect to http://localhost:8080 to exercise the the manager app, used that to declare the location of the sample.war file.And connect to http://localhost:8080/sample to display the  samples.
OK for me.
