Hello,

I have a Java app to run in a Tomcat server. I have to pass some arguments to the VM of Tomcat. One of them is:

-Dhttp.nonProxyHosts=127.0.0.1|localhost|*.my.fqdn.com

(Notice the "|" characters").

 

Sadly this parameter prevent the Tomcat startup and I got an error saying "localhost is not recognized as a command (...)"

I've tried multiple versions of this line but none of them are working. Eg:

"-Dhttp.nonProxyHosts=127.0.0.1|localhost|*.my.fqdn.com"
-Dhttp.nonProxyHosts="127.0.0.1|localhost|*.my.fqdn.com"
-Dhttp.nonProxyHosts=127.0.0.1\|localhost\|*.my.fqdn.com
-Dhttp.nonProxyHosts="127.0.0.1\|localhost\|*.my.fqdn.com"
...

Thank you for the help

Hello,

Try escaping pipes with a cap like this:

-Dhttp.nonProxyHosts=\"127.0.0.1^|localhost^|*.my.fqdn.com\"

In the end, with the line you provided Tomcat is able to start without error but the value of the option (nonProxyHosts) is not used by the VM !

I tested by removing the 127.0.0.1 and localhost values, leaving only the *.my.fqdn.com without caps & pipes and in this case the VM uses the option.

 

Do you have any idea ?

 

VM used is:

java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) Client VM (build 25.191-b12, mixed mode, sharing)

What if you try the following syntax:

-Dhttp.nonProxyHosts=127.0.0.1^|localhost^|*.my.fqdn.com

Nope, this one is not working. I'm wondering if on windows the double quotes should also take in the param key but I'm unable to find the right syntax :(

As a workaround, you can try adding the option directly to the <server-home>/conf/catalina.properties file like this:

http.nonProxyHosts=127.0.0.1|localhost|*.my.fqdn.com

Or adding the following line to the <server-home>/bin/catalina.bat file:

set "JAVA_OPTS=%JAVA_OPTS% -Dhttp.nonProxyHosts=127.0.0.1^|localhost^|*.my.fqdn.com"

Yes it's what I did. I created a setenv.bat in <server-home>/bin/setenv.bat

set "CATALINA_OPTS=%CATALINA_OPTS% -Dhttp.nonProxyHosts=127.0.0.1^|localhost^|*.my.fqdn.com"

But I would like to find the right spelling for this option in Intellij.

Thanks for confirming.

I created a new bug report for this on our issue tracker: IDEA-250881, and asked the responsible developer to take a look.
