Check the Servlet Spec (version 2.4 is at
http://www.jcp.org/aboutJava/communityprocess/final/jsr154/
) for questions of this kind.
From memory in both cases (so treat with caution):
1.) am I allowed to call main methods or programms in my web
applicatio?
If you wish to be spec-compliant, no. However, it should work depending
on Tomcat's security settings.
Really? I thought you could do anything within a Servlet that you can
do within normal Java code. Also, a restriction on calling the "main()"
method within a class seems nonsensical, because one can simply rename
that method.
2.) am I allowed to write files on the disk from within an
web application? If I am, something went wrong while trieing ;-)
Can i write anywhere or have I to write to my application dir
or to temp dir or something.
If you wish to be spec-compliant, you can only write to a temporary
directory that you ask the context for. However, this may or may not be
enforced depending on Tomcat's security settings.
This point I'm less sure on, but I would think it's the role of the
*servlet container* to be spec-compliant, not the programmer of a
servlet. But FWIW, the Tomcat Administration Web Application (separate
download in 5.5.x[1]) does alter the XML files located in the Tomcat
/conf directory. If the original questioner is having problems altering
text files located on the server, perhaps the code for the Admin
application would be a good reference for him.
