tomcat not starting

Question

suddenly for some reason tomcat server is not runnin/starting/stopping.

below is the result I get when i run the startup command,

  C:\Program Files\jasperserver-3.5.0\apache-tomcat\bin>startup
Using CATALINA_BASE:   C:\Program Files\jasperserver-3.5.0\apache-tomcat
Using CATALINA_HOME:   C:\Program Files\jasperserver-3.5.0\apache-tomcat
Using CATALINA_TMPDIR: C:\Program Files\jasperserver-3.5.0\apache-tomcat\temp
Using JRE_HOME:        C:\PROGRA~1\JASPER~1.0\java\jre

The tomcat window pops up for a split of a second and goes away.

(I have another java instance installed under c:\program files)

Help!!!

Answer 1

In my case that was a problem with final slash in %CATALINA_HOME% path: final slash should not be there!

C:\tomcat\8.0.30 - correct

C:\tomcat\8.0.30\ - wrong

See http://blackandwhitecomputer.blogspot.de/2015/09/tomcat-debug-cannot-startup.html

Honestly, I had not expected modern applications may be depended on final slash in environment variable path!

Answer 2

Hmm it's very strange problem because in the log you have that server started, so try this:

• restart computer :) - the best solution for strange situations
• change tomcat port
• close every unnecessary applications: skype, ip phones etc (I've encountered similar problem someday and application ip phone "softly" blocked this port ("softly" - in tomcat log everything was OK but in reality webapp doesn't work)

Answer 3

If Tomcat was earlier working fine and Tomcat not starting happens unexpectedly, it's because some other process has started using the port you were using Tomcat on. In my case, I had shutdown Tomcat and was trying to run my servlet directly from Eclipse. So Eclipse took control of the port. After I closed Eclipse and tried restarting Tomcat (with startup.bat), everything worked fine.

ykaganovich's answer helped me track down my issue.

Answer 4

I had the same problem and I solved it this way:

First, following @ykaganovich suggestions, I tried to start the server using the catalina.bat start command; it did not solve the problem, but at least it showed a log that specified the error, which was really helpful.

In my case, the log said that the problem was because of the java versión. I had the JAVA_HOME variable pointing to the JDK7, but my tomcat version needed it to point to the JDK8.

I changed the JAVA_HOME variable to point to JDK8 (instead of JDK7) and then , when I executed the catalina.bat start command again, it worked perfectly and the server started. I hope my suggestion could be helpful to someone.

Answer 5

Add tomcat in your eclipse and start it from there. Configure tomcat as 'Use Tomcat installation'. It will work

Answer 6

Try to open Tomcat7w.exe or follow the below steps.

(I have installed Tomcat under folder C:\Program Files\Apache Software Foundation\Tomcat 7.0)

1. open command prompt as Administrator
2. run --> "C:\Program Files\Apache Software Foundation\Tomcat 7.0\bin\Tomcat7w.exe" //MS//
3. now you can see icon in the system tray
4. double click on icon and start/stop
