Hello all, I just tried to temporarily set a system property within my module code, with unfavorable results: ```auto System.setProperty("sun.net.spi.nameservice.nameservers", "8.8.4.4,8.8.8.8"); ``` This is necessary because we want to make sure that domain names are not resolvable on the server… except by the module. Is there an Ignition-specific method of setting jvm system properties? Thank you for your help. ---

You may need to set this much earlier, on system startup. You can add JVM parameters to ignition.conf. Look for the “wrapper.java.additional” lines. It would look something like this: ```auto wrapper.java.additional.9=-Dsun.net.spi.nameservice.nameservers=8.8.4.4,8.8.8.8 ``` ---

Thanks, I’ll try this out.
