Servlet being executed twice

Question

          Hi all,
          I'm running WLS5.1, SP8 on W2K. I've written a servlet that instantiates and persists an entity bean. The servlet is registered in web.xml and mapped appropriately. If I run the servlet through the browser, everything works as expected.
          I've written a test case that opens a HttpURLConnection to the servlet, and instead of posting the data from a form (like through the browser), I appended the parameters to the querystring. When the test case executes, the servlet is executed twice, creating two identical rows in the database. So my test case fails expecting the entity to be unique.
          I see two servlet inits happening:
          <WebAppServletContext-vivaceApp> RequestProcessor: init
          and
          <ServletContext-General> classes: init
          Any ideas why this request is submitted twice?

What you might want to do instead of sending email directly from the trigger, is create a job which sends the email. This way you make the sending of the email part of your transaction. When you issue a commit, the job gets submitted and the email is sent. When you rollback, the job is removed and no email is sent.
