TechTip: Ensuring the Connection When a Domino Java Agent Calls a Domino Servlet

Because of the design of our existing application, we found that we needed a Domino Java agent to make a call to a Domino servlet. We were able to accomplish this by making use of the URL and HttpURLConnection classes in the Java API to have our agent establish the connection to the servlet.

When we first implemented the Domino agent call to the Domino servlet, we encountered a problem. The Domino agent called the Domino servlet and made the connection, and all seemed fine. But we realized that the connection never totally completed. After we added a statement in the Domino agent to print out the response from the servlet, it worked correctly. This is the example code, with the bolded text being what we added:


URL url = new URL ("yourServletURL");
HttpURLConnection httpConn = (HttpURLConnection)url.openConnection();

// Opening the connection to URL
httpConn.setDoOutput(true); // Can read from the connection
httpConn.setRequestMethod("GET");
httpConn.connect();

System.out.println("Response: " + httpConn.getResponseCode() + " " + httpConn.getResponseMessage());

httpConn.disconnect();
