Hi,
I had downloaded Camunda-bpm-tomcat-7.5.0 distribution and it was working until I rebooted my laptop.
I run the start-camunda.bat file but it’s not connecting to http://localhost:8080/camunda-welcome/index.html
Any ideas what went wrong? Where should I troubleshoot?
Thanks
Hi @kontrag,
could you check out tomcat logs if there is an error?
Can you open http://localhost:8080/camunda/app/tasklist/default ?
Cheers,
Askar
Hi @aakhmerov,
camunda-bpm-tomcat-7.5.0\server\apache-tomcat-8.0.24\logs folder is empty.
No, I cannot open that link either.
@kontrag,
are you running windows or linux? is tomcat process running? on linux ps -ef | grep tomcat. On Windows check in task manager.
Cheers,
Askar
I’m on windows, this is what I get when I run the start-camunda.bat
But in the browser, I cannot connect localhost.
could you check in task manager if tomcat process is running? Or on command line tasklist | FIND "tomcat". If it is running please kill it and start again.
Cheers,
Askar.
What should I look in task manager for? javaw.exe? I don’t see it.
Your command line doesn’t return anything.
ok so that means that tomcat is not starting for some reason. I see that you are using JRE_HOME, could you please install JDK and set JAVA_HOME environment variables?
Cheers,
Askar.
I had already installed JDK and JAVA_HOME environment variable is set.
then your tomcat is not using it for some reason. Please check your startup scripts if it’s overriden somewhere, if not then try inlining it there and see if that helps.
Cheers,
Askar
Thanks for your time first of all!!
I removed JRE_HOME from my User Variables and now it points to JDK and works.
But, for my understanding, which one does Tomcat need to run properly?
What if I want to set JRE_HOMe as a user variable for another reason?
Cheers
Hi @kontrag,
I think officially it needs JRE only. But JDK has some additional tools and libraries which are required for parts of functionality. As a rule of thumb, just use JDK unless it’s really important for you to use JRE.
You can read more explanations here:

In the first screenshot I posted, you can see that Tomcat was using
JRE_HOME= C:\Progra~1\Java\jre1.8.0_111
which was taken from the User Variables.
What I did to make it work was to add the following line in the ~camunda-bpm-tomcat-7.5.0\server\apache-tomcat-8.0.24\bin\setenv.bat
set “JRE_HOME=%ProgramFiles%\Java\jdk1.8.0_111\jre”
My question is: Is it fine that the JRE is taken from within the JDK folder? And not from its own JRE folder as the screenshot?
Thanks!
If people still have issues, it might have to do with your java 9 installation. The default bundled tomcat will not work on Java 9. You will have to downgrate to java 8, or install a more recent Tomcat installation.
See https://stackoverflow.com/questions/45917401/tomcat-7-0-73-doesnt-work-with-java-9 for more info.
Gosh! I could kiss you right now!!! thanks a lot! this solved it for me!!! 
Hi there,
For those who run into this situation as well: I ran into another reason why my Camunda Engine (Community Edition) wouldn’t start.
I was running it under WIndows 10 and I needed to launch the “start-cmunda.bat” from an “elevated command prompt” (ie. start cmd.exe as an administrator, navigate to the location where it is located and start it from there).
Regards,
Rob.
I keep getting Java.Net.Bind Exception on port 8080, Even after killing all the process in 8080. And it doesnt work even if I change the port number for tomcat
Apologies, i do realize this is a very old thread but still the only relevant one I could find so thought of posting it here. I have downloaded community edition from here==> https://downloads.camunda.cloud/release/camunda-bpm/run/7.15/camunda-bpm-run-7.15.0.zip
, and running the start batch file, but on the http://localhost:8080/camunda-welcome/index.html page, I get a whitelabel error page.
Environment variables are set already, but on the boot script on command line, i can see below:
2021-05-07 22:58:21.633 INFO 9588 — [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 8080 (http) with context path ‘’
Not sure if this is the reason for the issue. Can someone guide me please?
