Handle HTML5 form submission
HTML5 forms can be submitted to a servlet hosted in AEM. The submitted data can be accessed in the servlet as an input stream. To submit your HTML5 form, add an “HTTP Submit Button” on your form template using AEM Forms Designer.
Create your submit handler
A simple servlet can handle the HTML5 form submission. Extract the submitted data using the following code snippet. Download the servlet provided in this tutorial. Install the servlet using the package manager.
StringBuffer stringBuffer = new StringBuffer();
String line = null;
java.io.InputStreamReader isReader = new java.io.InputStreamReader(request.getInputStream(), "UTF-8");
java.io.BufferedReader reader = new java.io.BufferedReader(isReader);
while ((line = reader.readLine()) != null) {
stringBuffer.append(line);
}
System.out.println("The submitted form data is " + stringBuffer.toString());
Ensure you have configured the Adobe LiveCycle Client SDK Configuration if you plan to use the code to invoke a J2EE process.
