Don,

When I use the EsriShapeExport class to export a graphiclist of
EsriPolylines it always exports the shape file as type polygon. I want
it to eport a shape file of type polyline. The code is listed below.
Can you see anything that is wrong or missing?

private void downloadFile(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException
 {
 try
 {
 PrintWriter out = response.getWriter();
 response.setContentType(CONTENT_TYPE);

 String aoiVertices = getAOIVertices(request);
 String inputGeometryIds = getInputGeometryIds(request);
 String where = "[igeo_pk] IN(" + inputGeometryIds + ")";

 EsriGraphicList graphicList = new EsriPolylineList();

graphicList.setTraverseMode(OMGraphicList.LAST_ADDED_ON_TOP);

 EWInputGeometryList inputGeometryList = new
EWInputGeometryList();
 inputGeometryList.retrieve(where, "", 0, 0, 0);

 while (inputGeometryList.next())
 {
 EWInputGeometry inputGeometry = inputGeometryList.item
();

 float[] points = new float[10];
 points[0] = (float) inputGeometry.getUlLat();
 points[1] = (float) inputGeometry.getUlLon();
 points[2] = (float) inputGeometry.getLlLat();
 points[3] = (float) inputGeometry.getLlLon();
 points[4] = (float) inputGeometry.getLrLat();
 points[5] = (float) inputGeometry.getLrLon();
 points[6] = (float) inputGeometry.getUrLat();
 points[7] = (float) inputGeometry.getUrLon();
 points[8] = (float) inputGeometry.getUlLat();
 points[9] = (float) inputGeometry.getUlLon();

 EsriPolyline polyline = new EsriPolyline(points,
OMGraphic.DECIMAL_DEGREES, OMGraphic.LINETYPE_STRAIGHT);
 graphicList.add(polyline);

 inputGeometry = null;
 }

 inputGeometryList.close();

 int projType =
ProjectionFactory.getProjType(getProjectionType(request));
 float latitude = getLatitude(request);
 float longitude = getLongitude(request);
 int scale = getScale(request);
 int width = getWidth(request);
 int height = getHeight(request);

 Projection projection =
ProjectionFactory.makeProjection(projType,

latitude,

longitude,

scale,

width,

height);

 Date date = new Date();
 String fileName = date.toString();
 fileName = fileName.replaceAll(" ", "");
 fileName = fileName.replaceAll(":", "");

 EsriShapeExport esriShapeExport = new
EsriShapeExport(graphicList, projection, "/earthwhere_working/" +
fileName);
 esriShapeExport.export();

 out.write("<html>");
 out.write(aoiVertices + " ");
 out.write(inputGeometryIds + " ");
 out.write("</html>");
 }
 catch (Exception e)
 {
 PrintWriter out = response.getWriter();
 out.write(
 "<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.01
Transitional//EN'>");
 out.write("<html>\n");
 out.write("<head>");
 out.write("<title>EarthWhere Shape File Download</title>");
 out.write("<meta http-equiv='Content-Type'
content='text/html; charset=iso-8859-1'>");
 out.write("<link href='css/earthwhere.css' rel='stylesheet'
type='text/css'>");
 out.write("</head>");
 out.write("<body bgcolor='#ffffff'>");
 out.write("An error occurred while downloading the file.
Please contact your administrator with the message below. ");
 out.write(e.getMessage());
 out.write(" <input onclick='window.close();'
type='button' name='btnClose' id='btnClose' value='Close'>");
 out.write("</body>");
 out.write("</html>\n");
 }
 }
