[Resolved] doGet() being called twice??

I wrote a servlet that reads an HTML file, parses the contents, replaces certain delimited strings with some other values, and after that flushes the processed output to the client.

I find that in this servlet the doGet() method executes twice, although I am calling the servlet only once, through the browser.

.

Here's a theory:

Do you also declare a doPost something like this?

Code:

---


  /**
  * Linked to doGet so GET and POST are handled the same way
  */
  public void doPost(HttpServletRequest req, HttpServletResponse resp) {
    doGet(req, resp);
  }


---

For this to occur, your html would invoke the servlet with POST, plus you throw in some GET arguments as well like: /servlet?x=7&y=3, then in your servlet, both the doPost and the doGet fire because each has something unique to process. The thing is, the doPost is directed to execute the doGet. Voila! Two doGets.

I had a doPost() method declared which simply called doGet(). After I noticed that doGet() was being called twice, I commented out the doPost() method.

And the servlet is invoked by calling it directly in the URL itself, the parameters are passed in the URL string itself.

.

So is doGet() still being called twice?

Yep, I think that was the culprit. I commented out the doPost method and it worked.

Thanks for the help :)

However, I fail to understand how the doGet() and doPost() both are called, when I invoke the servlet by directly typing its URL in the address bar.
