I've got a fresh installation of Tomcat 7.0.56. When I run startup.bat (As administrator or not), I got the following message:
Using CATALINA_BASE: "C:\uPortal_test\apache-tomcat-7.0.56"
Using CATALINA_HOME: "C:\uPortal_test\apache-tomcat-7.0.56"
Using CATALINA_TMPDIR: "C:\uPortal_test\apache-tomcat-7.0.56\temp"
Using JRE_HOME: "C:\Program Files (x86)\Java\jdk1.7.0_71"
Using CLASSPATH: "C:\uPortal_test\apache-tomcat-7.0.56\bin\bootstrap.jar;C
:\uPortal_test\apache-tomcat-7.0.56\bin\tomcat-juli.jar"
And that's it. The console closes instantly. I followed this Tutorial
I set CATALINA_HOME at the beginning of startup.bat, just in case, but it should not be necessary
Ok you need to get the error from command prompt. You will need to do the following:
click on windows button
type cmd (followed by enter)
cd C:\uPortal_test\apache-tomcat-7.0.56\bin (followed by enter)
startup.bat (followed by enter)
If you run this batch file you some of the error will pop off the script which will give you hint what wrong you are doing and you can correct accordingly.
