If you're using Java 1.5+, the standard concurrent package provides
everything you need.
http://java.sun.com/j2se/1.5.0/docs/api/java/util/concurrent/package-summary.html#package_description
There should be several tutorial available for it and it's well with
understanding the various approaches. Prior to Java 1.5 there is a
library available that the concurrent package was derived from (I forget
the name).
Important: If you're creating your own threads within a container, it's
essential that you guarantee that the threads and their resources are
properly released. Failing to do so will prevent the container from
undeploying your application or shutting down cleanly. One technique to
assist with this is create your ExecutorService within a
ServletContextListener that uses the shutdown method to shutdown the
threads and release all resources. Another approach is to use a library
that provides this level of integration already (such as is available in
one of the Spring packages I believe).

Hi Dave,
You can just create any class that extends the Thread object or implements the
runnable interface. The required method, run(), should abstract what u want to
do, (connect to the 3rd party server). Instantiate that class then call its
start() method from the Struts action that should trigger it. Your action
should finish safely without waiting for that thread to finish. Note: this is
just a bare implementation, you might want to consider using thread pooling to
manage your resources. What exactly do you intend to do? Will you wait for a
response from your HTTPS server?

I have a function that POSTs data to a third party HTTPS server: void
postData(String sURL, String sData);
I need to call this function as a background thread from an Action class,
so that the user doesn't have to wait on the connection to establish. How
can I safely call this function so that it becomes a background thread?
Thanks,
Dave
