Warning: modified in the future

Question

I am getting the warning

Warning: sendmailpm.jsp modified in the future. 

What does this mean?

Answer 1

JSP files are compiled. Many servers also allow you to replace the files on a running server. It then compares the timestamp of the compiled source and the timestamp of the jsp file to determine if it needs to recompile.

If the file is dated in the future, the jsp file will always be newer than the class. This gives you a warning.

Check the timestamp on the file. Perhaps someone created it on a computer with an incorrect clock, and now it appears to be "created in the future". Or perhaps the server has the incorrect date (check timezone settings).

Are there remote file servers involved? Clock drift between a web server and a file server can cause this error too.

To diagnose this further, you'd have to give us some hints - what jsp server, what OS, what filesystem?
