Subject Re: OT: servlet 2.4: write a file to a war
Date Fri, 02 Jan 2004 03:37:54 GMT

The only place you can count on existing for writing is the tempdir defined 
by the servlet container.

File temp = (File)context.getAttribute("javax.servlet.context.tempdir");

Otherwise, you can set up a deployment parameter for your deployer to 
configure that specifies a directory for writing.  This can be either a 
JNDI environment variable or a context parameter.  You can set up defaults 
in the web.xml and the deployer can override these with proprietary server
