File locking when Jetty service is up [message #1809393]

Hi There,

I'm currently working with the Gradle project which is used to design an web services to deploy in the Jetty web server in the location "C:\Program Files\jetty\mt-base\webapps" as .WAR file. When I run the Jetty services, my services working fine as expected but what worrying me is, Jetty allowing the WAR file for modification even when Jetty is running and thus reloading the services to have effect on the server response for the client request.

This allows for malicious tampering of the WAR file and we are looking to protect this from happening.

My question is, Is there any Jetty configuration to lock the web application file while the service is up and running (I.E., lock all files inside "C:\Program Files\jetty\mt-base\webapps" folder)? If Yes, could you let me know how to setup the configurations for me, please?

Current Jetty I'm using is Jetty (x64) 1.4.0.56668

Thanks in advance!

You probably want to take that to the user mailing list shown on https://www.eclipse.org/jetty/mailinglists.html ,
but I think that's your operating system's responsibility, and not something to realistically worry about.

Hi There Nitin,

Thanks for getting back to me. I will post this in Jetty user mailing list as you have suggested. However, I do see a facility 'useFileMappedBuffer' property in the link https://wiki.eclipse.org/Jetty/Reference/webdefault.xml for memory-mapping of files for the Jetty services. I'm currently trying this to see if I can achieve my need.

Could you please let me know your thoughts on whether this 'useFileMappedBuffer' property will work or not?

Thanks in advance!
