It seems that you rename the ejs_circularvwee.jar to ejs_circularvwee25.jar.
I used the filename of the uploaded jar to find the ejs source (.xml or .ejs).
Because you rename ejs_circularvwee.jar to ejs_circularvwee.jar. so the server can not find the ejs source
and it stop the process.
Do not change the ejs generated jar filename. Upload as it is generated.
If you want another jar name, you should change the ejs source name.
I tried to change the code on the server so that it will accept .ejs as source.
