I am trying use the http://www.jfree.org/eastwood/index.html Eastwood Chart
Servlet , which is based off the http://code.google.com/apis/chart/ Google
Chart Api , with iText. Essentially you send a formatted url string off to
the servlet and it returns a .png image of the chart. This works great for
html pages, but now I am trying embed the chart urls as images in iText
without much success. For example:
Image img = Image.getInstance(testUrl);
Where testUrl is a String or URL (I've tried both and if you look at the
code they are essentially the same thing).
This results in this error:
java.io.IOException: Server returned HTTP response code: 406 for URL:
testUrl
at
sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1170)
at java.net.URL.openStream(URL.java:1007)
at com.lowagie.text.Image.getInstance(Unknown Source)
at com.lowagie.text.Image.getInstance(Unknown Source)
That is just the top of the stack trace, as the rest is program specific.
testUrl is a stand-in for the actual url.
I took a look at the HTTP header with snort and it looks like this:
testUrl HTTP/1.1..User-Agent: Java/1.5.0_14..Host:
devjrun..Accept:text/html, image/gif, image/jpeg, *; q=.2,
*/*;q=.2..Proxy-Connection: keep-alive....
This returns a 406 not accepted from the server with a message "Your request
used a protocol that is not currently supported."
Essential I've hit a wall and I have no idea about how to get this to work.
Any ideas/suggestions would be greatly welcome.
Thanks.
