Tomcat 不启动。 我哪里错了？

Question

I did everything according to the instructions, installed all environment variables, but it still does not start. This is what is output in cmd when I try to start:

C:\WINDOWS\system32>%CATALINA_HOME%\bin\startup.bat
Using CATALINA_BASE:   "D:\Tomcat"
Using CATALINA_HOME:   "D:\Tomcat"
Using CATALINA_TMPDIR: "D:\Tomcat\temp"
Using JRE_HOME:        "C:\Program Files\Java\jre1.8.0_131"
Using CLASSPATH:       "D:\Tomcat\bin\bootstrap.jar;D:\Tomcat\bin\tomcat-juli.jar"
C:\WINDOWS\system32>

A window is opened for the bat and disappears immediately. There is nothing on http://127.0.0.1:8080/ . What could be the problem? Contents of startup.bat:

Answer 1

This is most likely a duplicate question, but neither of the other answers that I found with a quick lookup contained the basic technique on how to find out the root cause for yourself, thus I'm answering here:

When the command line that startup.bat starts immediately disappears, just use catalina.bat run , which will start tomcat in the same command line that you're currently running (of course, this only works from command line, you can't doubleclick any more). The error message that otherwise would be shown in the (immediately disappearing) newly opened command line window, will stay visible in your current command line.

Most likely, the same content is also found in logs/catalina.out and you should check that file as well.

Answer 2

For me it was because there is a space in Program Files between Program and Files and it couldn't recognize the path. I changed the path of my project and moved it under Documents and it worked.
