NetBeans can not start Tomcat on mac

Question

I am trying to run Tomcat using NetBeans on Mac. When I execute startup.sh in bin folder and then access http://localhost:8080 everything looks great. Then I tried running my JAVA project in NetBeans, but it said that port 8080 is already in use. So I found which process is running on this port using lsof -i :8080 and killed it (or executed shutdown.sh in bin folder, it is the same).

Then I tried to run my project in NetBeans and after over 3 minutes of waiting it says this

.../WebApplication/nbproject/build-impl.xml:1045: Deployment error: Starting of Tomcat failed.

There is log:

Can you guys help me? I do not know what to solve this several days...

Answer 1

I had the same problem.

What my problem was I was using wrong jdk version for netbeans. For example, I was using jdk version java-1.8 with netbeans 12. I changed the JDK version to the latest and tried running tomcat again and it started working.

It took me a week to figure this thing out. All the other options didn't work for me.

Answer 2

From the Comments:

In Netbeans, go to Tools -> Options -> and select No Proxy (if you're not behind the proxy server)

- Shashanth

To resume this for both Mac OS and Windows:

• on Mac: Go to Netbreans Preferences, and there choose "No Proxy".
• on Windows, Go to Tools, then Options, and there choose "No Proxy".

I'm answering this so other users with the same problem can easily determine the answer that was provided.

You can try installing XAMPP for mac it explicitly runs the server for you to run your application or you can try with Apache Tomee server. XAMPP: https://www.apachefriends.org/download.html TOMEE: http://tomee.apache.org/downloads.html
