permission to write a file (with java)

[sburkard]

hi there

i've wrote a piece of java-code that runs great if i start it from eclipse.

when i pack it to a jar-file and put it in the customtags folder, i get an
IOException where it tries to write a file to disk. well, the file itself is
written, but it's size is zero bytes.

are there any restrictions for java-classes (custom tags) to write to the
filesystem?

thanks and greetings
stefan
