Newbie problem

Hi all

I'm using axis 1.4 for connecting a Struts application with a legacy 
database system. The class that implements the query from the server 
side, makes a system call to an executable (that is one of  the tools 
for accessing the database system) and sends to the Struts application 
the results. The Struts application could eventually send some large 
data to be updated in the database. As the command line has some limits, 
I´d preferr that the class that implements the service, create a new 
temporary file that will be consumed by the executable.

1. The temporary file should have a unique name and should be thread 
safe. I mean that eventually will have many users trying to update or 
add data, and each one will generate its own temporary file. The class 
that implements the update or add to the database could make this files 
using random generators, but I preferr to include some kind of axis 
identification, for instance for the thread or the process number, could 
be used some axis property that could be concatenated with the rand number?

2. I'm developing over Win32 platform. In Linux, which special reghts 
considerations should attend for enabling the posibility to generate the 
temporary files?
    I suppose that Tomcat should be authorized to access to the 
executable and write the temporary file in some directory. Anybody has 
experiences over that issue?

3. Ignorance....How could I configure in a standard way a config xml 
file. I wish to include in this file, the location for the executable, 
the temporary folder in which the temporary files will be created and so on.

Thanks a lot
Emiliano Marmonti.
