Today, I watched the video of Lao Du’s servlet and tried to start the Tomcat server after typing the code. I found this: error running ‘tomee 10.0.121 ‘: the selected directory is not a tomee Hom error.

Then I didn’t look at the error carefully. Subconsciously, I thought my Tomcat path was wrong. I looked it up and found that there was no problem

Finally, take a closer look at the good guy Tomcat created to tomcatee. No wonder it can’t be started.

Solution:

Just change back to normal Tomcat

Finally, click the servlet according to the old Du code
