AW: chart in jsp
JFreeChart verwende ich für die Routerüberwachung. Dort wird angeblich das 2d Api korrekt unterstütz. Damit müßte das Teil auch serverseitig vernünftig laufen.

JFreeChart is an open-source Java class library for generating charts and has the following features: * supports bar charts (horizontal and vertical), line charts, pie charts, xy-plots (numerical and time series) and high/low/open/close charts; * uses data from any source that supports the defined interfaces; * based on the Java 2D API; * available in source code form (subject to the terms of the GNU Lesser General Public Licence); * requires JDK 1.2.2 or later; You could also have a look at jetchart. It's a very easy to use and versatile java applet. I'ts not a free package but it's not too expensive (around $160). You can find it at: www.jinsight.com You can trap interaction with the graphic (if the user clicks on a bar, you can branch to an hyperlink, etc). Hope that helps, Regards, Todd G.

Re: chart in jsp
hi jeff ,hi all,
the servlet you use is a servlet 2.3 stuff, i think.
is there any url to take a look at this code?
i am involved in creating svg's and not very familar with writing servlets.
but i'd like to show my interactive work.
i tried this ( i found in german java-magazin 04/2001):
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import org.apache.batik.transcoder.*;
import org.xml.sax.*;
import java.io.*;
public class BatikFilter implements Filter{
private FilterConfig config = null;
private String format = "jpeg";
public BatikFilter() {
}
public void doFilter(ServletRequest parm1, ServletResponse parm2,
FilterChain parm3) throws java.io.IOException,
javax.servlet.ServletException {
SpoofResponse spoof = new SpoofResponse();
parm3.doFilter(parm1, spoof);
String uri = "";
if (parm1 instanceof HttpServletRequest)
{
HttpServletRequest httpReq = (HttpServletRequest) parm1;
uri = httpReq.getRequestURI().toString();
}
String localFormat = (String) parm1.getParameter("format");
if (localFormat != null) format = localFormat;
try
{
String ctype = parm1.getContentType();
if ((ctype == null) | ((ctype != null) (ctype.indexOf("svg")
!= -1)))
{
Class transcoderClass = (Class) handlers.get(format);
if (transcoderClass == null) return;
Transcoder trans = (Transcoder) transcoderClass.newInstance();
trans.addTranscodingHint(org.apache.batik.transcoder.XMLAbstractTranscoder.K
EY_XML_PARSER_CLASSNAME,
"org.xml.sax.XMLReader");
ByteArrayOutputStream os = new ByteArrayOutputStream();
TranscoderInput tip = new TranscoderInput (new InputStreamReader
(new ByteArrayInputStream (spoof.getBuffer(;
tip.setURI(uri);
TranscoderOutput top;
if (format.equals ("svg"))
{
top = new TranscoderOutput (new OutputStreamWriter (os));
}
else
{
top = new TranscoderOutput (os);
}
trans.transcode(tip, top);
byte[] buffer = os.toByteArray();
parm2.setContentType((String) mimetypes.get(format));
parm2.getOutputStream().write(buffer);
}
else
{
String result = "htmlbodyContent filtered!/body/html";
parm2.setContentType("text/html");
parm2.reset();
parm2.getWriter().print(result);
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
public FilterConfig getFilterConfig() {
return config;
}
public void setFilterConfig(FilterConfig parm1) {
config = parm1;
}
private static Map handlers = new HashMap();
private static Map mimetypes = new HashMap();
{
handlers.put ("jpeg",
org.apache.batik.transcoder.image.JPEGTranscoder.class);
handlers.put ("png",
org.apache.batik.transcoder.image.PNGTranscoder.class);
handlers.put ("svg",
org.apache.batik.transcoder.svg2svg.SVGTranscoder.class);
mimetypes.put ("jpeg", "image/jpeg");
mimetypes.put ("png", "image/png");
mimetypes.put ("svg", "image/svg+xml");
}
}
class SpoofResponse extends ResponseBase { }
but sax isn't instanciated correctly( no empty public constructor)
any idea that makes me happy?
thanks
stefan
