I install the GeoServer 2.18 in Windows Server 2012 r2, and with tomcat 9, JRE 1.8. it works fine. but I cannot change the layer title/name. when I want to change the name, and I will get the error message


I find some way to try to fix, like use the Xmax=512M,

How do I solve this?

  • Works for me with GeoServer 2.18 on Windows 10. I could change the names and titles of the demo layers without errors. What browser do you have on Windows Server 2012?

Run the startup.bat file with Run as administrator then you can change the layers name easily.


In the final, I change the authority of webapp/geoserver folder. It works now.
