Unable to start Tomcat

Question

I'm trying to start Tomcat in Netbeans, unfortunately it is stuck at "org.apache.catalina.startup.Catalina.start Server startup in 793 ms". After a while I get an error message popup saying that starting Tomcat failed. I'm using Mac OS

This is all the output I see:

Can someone please help me?

Answer 1

In my Windows machine, I solved the problem using the following links:

https://geekflare.com/tomcat-stuck-at-startup/

Summary of the link:

1. Go to Tomcat installation folder and then bin
2. Open catalina.sh using the vi editor
3. Search for JAVA_OPTS and add the following

-Djava.security.egd=file:/dev/./urandom 4. Save the file and restart Tomcat

Answer 2

None of the other answers helped for me and nothing was logged anywhere either, so I went the long way and debugged NetBeans in the Java debugger to find out what was going wrong. It made me discover that NetBeans was denied a TCP socket connection to the Tomcat Manager webapp, which made it falsely assume Tomcat wasn't alive.

Solution:

Add

-J-Djava.net.preferIPv4Stack=true

to the command line options in netbeans.conf file (key "netbeans_default_options").

If this still doesn't help for you, you can set a breakpoint in org.netbeans.modules.tomcat5.util.Utils#pingTomcat() and trace what's happening from there.

Answer 3

Had a problem with the same symptoms, turned out manager.xml was missing from CATALINA_BASE/conf/localhost, so Tomcat's manager app wasn't starting so Netbeans couldn't talk to it. Installing a manager.xml file with following contents fixed the problem:

<Context docBase="${catalina.home}/webapps/manager" antiResourceLocking="false" privileged="true"/>

Answer 4

Happened to me on my mac.

The cause was network change => I set static IP on network settings.

Answer 5

I've found the fix by editing server.xml and adding server="XXXXXXX", where XXXXXXX should be the same name as web server found in netbeans.

For example, server="Apache Tomcat or TomEE"

Answer 6

I have the same issue, but this solves the problem:

Hi, I just want to point out an observation. I discovered that starting tomee 1.7.2 (plus) as a server in netbeans, netbeans is not too happy about the server="Apache TomEE" config on the 8080 connector. So by removing this one startup is OK again.

I guess a bug in the netbeans tomee (and tomcat) extention.

Answer 7

Try something:
- Enter your web application path correctly, manually in web browser address bar.
- Because IDE don't know start path. Or you must set up <welcome-files-list> element in web.xml.

Answer 8

Check in your web browser, if after starting tomcat you can reach localhost (if you haven't changed port number, it's under: http://localhost:8080/).

If it works: - There is problem with application- server communication (Have you properly deployed your app? Is there any firewall, which might block your app from running?)

If not: Tomcat is configured incorrectly. You might try to start it outside Netbeans (e.g. in console) to see if it works. If not, reinstall Tomcat.
