How set JENKINS_JAVA_OPTIONS under Windows ( Exception: URI must start with a slash ) ?

[Ed Sutton]

"Error 400 Status Code: 400< Exception: URI must start with a slash."

I do not understand why, but under Linux, editing /etc/sysconfig/jenkins fixed this problem. What is the equivalent configuration file under Windows XP?

Under Linux, adding -Dhudson.DNSMultiCast.disabled=true to the /etc/sysconfig/jenkins JENKINS_JAVA_OPTIONS line seemed to fix. No clue why.

## Type: string
## Default: "-Djava.awt.headless=true"
## ServiceRestart: jenkins
#
# Options to pass to java when running Jenkins.

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Dhudson.DNSMultiCast.disabled=true"

Setting it via Control Panel -> System -> Advanced -> Environment Variables should do the trick I'd think (either as a the Jenkins' user environment or System wide)  (Note I haven't done it myself so can't guarantee success :) )

Are you running it as a windows service? If so, just update the
<arguments> element in the service config file and restart the
service. The config file can be found at %JENKINS_HOME%\jenkins.xml

Cheers, Geoff

Yes, the Windows native package installs Jenkins as a Windows service and the config file was installed to:

C:\Program Files\Jenkins\jenkins.xml

As you suggested, I updated the <arguments> element and all is good! Thank you for your help!

Now if I can only figure out how to make the Windows Jenkins a slave to my Linux Jenkins master, then Jenkins will rule them all !

Take a look at

The jnlp slave as a service setup is pretty easy.

Sorry tried to make this clear in the other thread.

You simply do not need to install the Jenkins server on a slave node.  You are best off uninstalling it.

The master node, after being told about a slave node via the configuration page, will connect to the slave node and transfer to it the jars it needs in order to run a slave agent.  

It will, if configured, install the slave agent as a windows service too.  

You are able to set environment variables to be used in the slave agent's environment from the slave node's configuration page on the master.

Hope that's clearer.
