I have deployed same war file on my local machine tomcat and on a Virtual machine tomcat with export enabled true. When I access local machine url I see the option to download screenshot of graph but when I open VM url , I do not the same option rest graphs and display is same. Can you please check if this is an issue?
It should work fine irrespective of project being deployed, whether local or virtual machine. We created a simple java-project with exporting-chart feature in local machine, exported it as war. And we imported the war file in virtual machine(We are using Hyper-V) and tried export-chart feature in VM and found its working without any issue.
We even tried importing the sample project(JSP Samples, available in download page) in both local machine and VM and observed its working fine.
If you can guide us to reproduce the issue, either steps or a simple project(war file) with the issue, we can try resolving it.
