this code works on built in eclipse tomcat but dont work on ordinary tomcat
server
What's the error you are getting?
i dont get any errors in tomcat logs neither in localhost log nor stdout log
Note: When posting a question on usenet, its best to:
1. Describe the problem
I have an application which save own state to a properties files after user
logoff. It works when I did it on my computer on tomcat included in eclipse
IDE but it didnt work(dont save file) when i try deploy application on other
computer on ordinary tomcat. Tomcat doesnt let overwrite files or what??
Pls help
2. Show us what you did (i.e., complete compilable code).

3. Tell us the error you are getting.

4. Tell us what you are expecting to happen.
