Cant start Karma on windows

[Guiz]

Karma doesn't start on windows.

It says "Startingkarma..." and "Launching Karma. Go to http://localhost:8080 if it doesn't launch."
but then I can't connect on localhost:8080.

I verified my JAVA_HOME with jdk1.7.0_80 on 64 bits.
I don't know what to do more to make it works since I have no message error.
I tried by downloading Karma version v2.053 (but the file version say v1.3.3)

Any help ?

Hi,

(1) Make sure port 8080 is not in use by another application.
(2) For Windows, you need to set heap size to be 2 GB. Please restart Karma after resetting this. (You will see option on the top right corner of Karma window)

If it still does not work, please let me know.

Thanks

from the result of netstat -a, i confirm that the 8080 is not in use.
heap size at 2Gb and after restart of Karma still same result.

Thanks for your help and quick answer.

You should be getting a Tomcat window on startup or after restarting Karma from Karma window.

Can you please paste logs from that window ?

Thanks

I got no Tomcat window on startup neither on restarting karma from karma window.

I have the exact same issue. Any fix for this ??

Hi @akshayrana1139 & @guizmoau.

Which version of windows you guys are running?

Windows 10 and tried with all versions of Java. It does not start the tomcat server automatically and directly jumps to the line "Launching Karma. Go to localhost..."

Is there a way to manually start the server and then link this to that until the issue is resolved ?

Hi,
I am running Windows 10 64bit.
The localhost:8080 eventually launched after reinstalling the 64 bit version of the Java JRE and running karma.exe as administrator.
I hope it helps. John-Paul

Hi @devJpv,
Thanks for the comment.

We have to install appropriate version of JAVA. (64 bit JAVA for 64 bit OS.) (https://github.com/usc-isi-i2/Web-Karma/wiki/Installation%3A-One-Click-Install).

@akshayrana1139 , can you try above steps and check whether it is working or not.

Thanks

@kaushalv274 I tried everything and still the same thing. How can I start this if I manually start the tomcat.

I am also having guizmoau's problem launching Karma on Windows. I can confirm that port 8080 is open. It appears that java.exe is writing a rule to the firewall to block Karma. I will also check to make sure that I am running Java 64bit.

If this makes a difference, I am running Win 7 64-bit.

Thanks for any assistance you can provide.

Hi @akshayrana1139, you can do source code install if you want to start from command line. (https://github.com/usc-isi-i2/Web-Karma/wiki/Installation%3A-Source-Code)

@hlong35, Windows Firewall should allow karma.exe to run.

In case this information is helpful, I am running Win 7.

Thanks--

In case this is helpful to someone else, I got it to run:

1. Open a cmd prompt
2. Change the directory to the tomcat\bin directory ("cd C:\Program Files\Karma-Windows\Karma-Windows\resources\app\tomcat\bin")
3. Start tomcat ("startup")
4. Then right click on Karma and run it as an administrator.
   SOLUTION: INSTALL KARMA IN A FILE PATH WITH NO SPACES.

[Kaushal]

Hi everyone,

As suggested by @hlong35, space in the path is crating issue. As of now make sure the installation directory does not have any space in the filepath.

Please refer to updated wiki (https://github.com/usc-isi-i2/Web-Karma/wiki/Installation%3A-One-Click-Install)

I have my CATALINA_HOME set on Tomcat in some other directory. When I run startup.bat in any of the Tomcats (the one with CATALINA_HOME or the one with karma-windows/resources/app) and then run karma.exe, it opens a tomcat window but nothing else happens.
