I just got charts to work with a couple of changes to
com.icesoft.faces.component.outputchart.OutputChart

Code:

  public String getPath() {
  String folder = "/";
  if (getFacesContext() != null
  && getFacesContext().getExternalContext() != null) {
  if (DOMResponseWriter.isStreamWriting()) {
  folder = "./web/chart/images";
  } else {
  Object ctx = getFacesContext().getExternalContext()
  .getContext();
  if (ctx instanceof ServletContext) {
  folder = ((ServletContext) ctx).getRealPath("charts");
  } else {
  folder = ((PortletContext) ctx).getRealPath("charts");
  }
  }
  }
  return folder;
  }
 





Code:

private String getChartFileName() {
  Object req = FacesContext.getCurrentInstance().getExternalContext()
  .getRequest();
  String sessionId = "";
 
  if (req instanceof HttpServletRequest) {
  sessionId = ((HttpServletRequest) req).getRequestedSessionId();
  } else {
  sessionId = ((RenderRequest) req).getRequestedSessionId();
  }
  return this.getType()
  + this.getClientId(FacesContext.getCurrentInstance())
  .replaceAll(":", "") + sessionId + imageCounter++
  + ".jpeg";
  }
