public ClsServlet() {
super();
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
String appModuleName = "image.model.AppModule";
String appModuleConfig = "TempAppModule";
String imgno = request.getParameter("imgno");
String tblName = request.getParameter("tblnm");
String clmName = request.getParameter("clnm");
String pkclmName = request.getParameter("pkclnm");
String mType ;//= request.getParameter("mtype");
mType = "jpg";
String voQuery =
"select " + clmName + " from " + tblName + " where " + pkclmName +
" = '" + imgno + "'";
String mimeType =
mType; //"gif";//this.getServletConfig().getInitParameter("gif");
ApplicationModule am =
Configuration.createRootApplicationModule(appModuleName,
appModuleConfig);
am.clearVOCaches("TempView", true);
ViewObject vo = null;
//String s;
System.out.println("voQuery="+voQuery);
try {
vo = am.createViewObjectFromQueryStmt("TempView", voQuery);
} catch (Exception e) {
System.out.println( e.toString()+" err:VO Exists...");
System.out.println("before run============= !!!");
// Run the query
try {
vo.executeQuery();
} catch (Exception e) {
System.out.println(e.toString());
// Get the result (only the first row is taken into account
System.out.println("after run============= !!!");
Row product = vo.first();
BlobDomain image = null;
// Check if a row has been found
if (product != null) {
System.out.println("onside product============= !!!");
// We assume the Blob to be the first a field
image = (BlobDomain)product.getAttribute(0);
if (product.getAttributeCount() > 1) {
mimeType = (String)product.getAttribute(1);
} else {
//LOG.warn("No row found to get image from !!!");
//LOG.warn("No row found to get image from !!!");
System.out.println("No row found to get image from !!!");
vo.remove();
//vo.clearCache();
return;
System.out.println("Set Image============= !!!");
// Set the content-type. Only images are taken into account
response.setContentType("image/" + mimeType);
OutputStream os = response.getOutputStream();
InputStream is = image.getInputStream();
System.out.println(image.getBufferSize() + "image.getBufferSize()");
// copy blob to output
byte[] buffer = new byte[image.getBufferSize()];
int nread;
vo.remove();
//while ((nread = is.read(buffer)) != -1) {
while ((nread = is.read(buffer)) != -1) {
// try {
os.write(buffer);
System.out.println(buffer.length + "Set Image============= loop!!! " +
nread);
System.out.println("==out strim===" + os.toString());
is.close();
os.close();
os.flush();
// Remove the temporary viewobject
vo.remove();
//vo.clearCache();
// Release the appModule
Configuration.releaseRootApplicationModule(am, true);
how can i show this image

Answer 1

Hard to tell from your code and the information given.
Do you get the image from the DB?
Can you shoe the code to show the image on the page?
