I have a designed a PDF form using LiveCycle Designer 8. The form has a Submit button which on clicking invokes a Servlet sitting on a websphere server and then passes the data to the Servlet. The Servlet sends a TEXT/HTML response object.
I am able to successfully the form data using Adobe Reader 9 and Acrobat 8. However, when I try to submit the data using Adobe Reader 7, instantly I get an error message. The message just says "ERROR 500". Can someone please let me know what is going on here and how it can be corrected.
Acrobat/Reader is not a browser and as susch does not understand HTML commands. If the form is being hosted by a browser then the browser will recieve the HTML and interpret the commands. If you return back a response as a PDF instead of an HTML page then Acrobat/Reader will be able to interpret that.
