Enabling File I/O on a MapleNet Server


How can I enable file input/output on a MapleNet server?


By default system calls and file input/output are disabled for security reasons. Allowing file I/O on a public MapleNet server can be a major security hole that could allow user submitted worksheets to read files on the server. In a controlled environment, it is possible to setup the server to allow File I/O but worksheets would have to be reviewed to ensure they do not compromise server security.

The restriction on file I/O can be overridden is by removing the -z option in the line

kernel.localhost.program_args=-noclient -jgui -z

and commenting out the line


in the file


where $TOMCAT is the Tomcat installation folder

(e.g. C:\Program Files\Apache Software Foundation\Tomcat 6.0)
