Keeping Information across restart of webapps

[Steffen Schlachter]

I want to track some information across multiple restarts of my
webapp.

The problem is as follows: Every time my service fails I want to
increase a counter. Sometime I need to restart my webapp but I want to
keep the values stored in the counter.

I am using Tomcat 5 and Servlets. Can anyone give me a hint?

Regards,

Steffen

Hi,

why don't you simply store the counter in a File? When your webapp
(re)starts, just read the file, do a counter++ and rewrite the file.

HTH. Greetings,

As Stefan suggested, storing the counter's value in a file is a
reasonable solution. You may find it easier to use the Preferences API
available as of Java 1.4.

Other (not so straight forward) options include storing the counter in
a simple table and incrementing them on restarts as well
