Submit the form XML to a URL over HTTP
1 Accepted Solution
If you are unfamiliar with Java this may be a challenge. The servlet below uses the Java IO package to convert the servlet input stream to a string buffer to a string. The DOM4J XML parser is then used to convert the string to an XML document. The servlet writes the XML document to c:\\pdf.xml and sends an HTML response back to the browser (and Preview in Designer which is actually an HTML container) indicating "The XML data was successfully written to c://pdf.xml." A sample pdf.xml is attached.
NOTE: You cannot submit data from the attached PDF in Reader or Acrobat stand-alone. The PDF has to be opened in a browser. Additional scripting is required to submit data from a PDF in Reader or Acrobat stand-alone.
From LiveCycle Designer Preview I can fill the form with data and hit the Submit button resulting a call to the servlet.
The servlet responds with HTML which is written in the browser container.
DOM4J is the simplest of the XML parsers for the task. You will need to use a Java IDE such as Eclipse to configure a project to use the Java APIs, the servlet APIs and DOM4J. Alternatively you can use a good old fashioned text editor and a batch file to compile the Java class.
