Images used by jsp's

Is it a good idea to include image resources (like .gif and .jpg) used by jsps into the web.xml file? If so, how or what is the best way to include such resources in the web.xml file?
Thanks in advance, Ali

What exactly are you trying to do?

How to upload image using JSP

hi,
i am confronting a problem how to upload image from local PC to web server . I am using Tomcat 4.0
please help me by sending code
thanks

Hi,
Here is the solution for uploading images and displaying images. I am using struts with JSP, so this code has a Action and ActionForm class. You can put the same code in Java Beans or Servlet class to run it. This code has two JSP files - one for Upload (upload.jsp)and other for Image(image.jsp) display. It has a Servlet also to display the image. Here is the code file wise.
Upload.jsp **********************************************************
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:html>
<head>
<title>New Page 1</title>
</head>
<body>
<html:form action="uploadAction.do" enctype="multipart/form-data" method="POST">
File to upload
<html:file property="fileUpload" size="20"/>
<html:submit value="Upload" property="upload"/>
 
<html:img src="image.jsp"/>
 
</html:form>
</body>
</html:html>
Image.jsp*****************************************************************
<jsp:useBean id="upload" class="uploadtest.uploadActionForm" scope="session">
</jsp:useBean>
<%
 byte[] rgb=(byte[])session.getAttribute("byte");
 request.setAttribute("byArr", rgb);
%>

Image is
<jsp:forward page="/showimage" />
Struts Action Class - UploadAction.java **************************************************
import javax.servlet.http.*;
import java.io.*;
import org.apache.struts.upload.FormFile;
import org.apache.struts.action.*;
public class uploadAction extends Action {
public ActionForward execute(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
uploadActionForm upload = (uploadActionForm) actionForm;
try {
int size=upload.getFileUpload().getFileSize();
//if (image != null) {
byte[] byteArr = new byte[size];
//Create an input stream to read the uploaded file.
ByteArrayInputStream bytein = new ByteArrayInputStream(upload.getFileUpload().getFileData());
// Load the input stream into the byte Array.
bytein.read(byteArr);
// Close the input stream.
bytein.close();
// Load the byte[] into the content field.
upload.setContent(byteArr);
HttpSession ses=httpServletRequest.getSession();
ses.setAttribute("byte",byteArr);
return actionMapping.findForward("success");
} catch (Exception ex) {
ex.printStackTrace();
return actionMapping.findForward("success");
Struts ActionForm class ---uploadActionForm.java***************************************************
package uploadtest;
import org.apache.struts.action.*;
import org.apache.struts.upload.*;
import javax.servlet.http.*;
public class uploadActionForm extends ActionForm {
private FormFile fileUpload;
private byte[] content;
public FormFile getFileUpload() {
return fileUpload;
public void setFileUpload(FormFile fileUpload) {
this.fileUpload = fileUpload;
public byte[] getContent()
return content;
public void setContent(byte[] theFile)
this.content = theFile;
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
/**@todo: finish this method, this is just the skeleton.*/
return null;
public void reset(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
Servlet to display image --- ShowImage.java ********************************************************
import java.io.*;
import java.util.*;
public class ShowImage extends HttpServlet {
//Initialize global variables
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
byte[] rgb = (byte[]) request.getAttribute("byArr");
if (rgb != null)
response.setContentType("image/gif");
OutputStream stream = response.getOutputStream();
stream.write(rgb);
else
response.setContentType("text");
response.getWriter().write("attribute byArr not found");
This code will enable to to upload and display the image. If you know Struts, then you can write the Struts-Config.xml file by yourself. Other wise write to me, I will send you that. If you want to save the image in database, then you have to keep it as BLOB datatype is database. For database you need to send the byte array in the uploadAction.java file to database. Database will keep the image as binary.
Thanks

HELP!!!!Display blob image using JSP

Hi,
I am trying to blob image using JSP but it did not display successfully.
Can someone help, please?
below are the codes snippet:
<td>
<img src="display_image.jsp?ID=<%=request.getParameter("ID") %>" width="115" border="0">
</td>
byte[] image_blob = details.getImageByteArray();
response.setContentType("image/jpeg");
//response.setContentType("image/gif");
//BEGINNING OF SECTION TO DISPLAY IMAGE
/*OutputStream fos = null;
fos = response.getOutputStream();
fos.write(image_blob, 0, image_blob.length);
fos.flush();
fos.close();*/
java.io.FileOutputStream fos1 = new java.io.FileOutputStream("C:\\"+id+".jpg");
fos1.write(image_blob);
fos1.close();
OutputStream o = response.getOutputStream();
System.out.println("o");
o.write(image_blob);
System.out.println(image_blob);
System.out.println("write image");

Use Java Image or BufferedImage instead of obscure byte array for image data.
Here's an example code for a JSP document:
<%
String wid = request.getParameter("percent");
String cost = request.getParameter("suchi");
response.reset(); //IMPORTANT !
response.setContentType("image/jpeg");
// for testing purpose
if (wid == null) wid = "58";
if (cost == null) cost = "3400";
float dleng = Float.parseFloat(wid) * 2.6f;
RenderedImage rimg = drawGraph(dleng);
OutputStream os = response.getOutputStream();
try{
ImageIO.write(rimg, "jpg", os);
catch(IOException e){
os.flush();
%>
<%!
public RenderedImage drawGraph(float barLength){
final int w = 800;
final int h = 18;
final int x = 0;
final int y = 0;
BufferedImage img = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = img.createGraphics();
Color c = new Color(Integer.parseInt("FF9999", 16));
g2.setColor(Color.yellow);
g2.fillRect(x, y, w, h);
g2.setColor(c);
g2.fillRect(x, y, (int)barLength, h);
g2.dispose();
return img;
%>

Display BLOB Image in a JSP page.

Hi, Is there any easy way to display a Image in the browser using a JSP and an Oracle BLOB. I would like any code examples that anyone can provide me. I would like as many ways to do this as possible.
Thanks Brian

You can do it in 2 ways:
1. Get the BLOB from the DB and then write it into the local harddisk where the Web Server is located and then give the path in the <IMG SRC> Tag.
2. In the JSP, when you specify a IMG Tag
<IMG SRC='FileDisplayServlet?hdImgName=new.gif'>
This SRC is pointing to a Servlet. The Servlet will read the Query String and then go hit the DB, get the BLOB Content and then convert into a byte array. Now the servlet will change its content type to image or gif. Then it will write the content in the out stream.
Hope this helps.
Thanks and regards,
Pazhanikanthan. P

Hi Nick, I do see information on creating a slideshow with Quicktime at: http://www.apple.com/quicktime/tutorials/slideshow.html
however it appears Quicktime X removed that capability. There is no 'open image sequence' option from the File menu in Quicktime X.
If I do end up sticking with Final Cut - would you recommend any codec and/or dimension size that would result in the best quality or the most crisp image? I also need a few fade in's and out's on various parts - I don't believe I would have the control without Final Cut.
Would resizing the image files in Photoshop to 1920 pixels by 1280 before importing them into Final Cut result in crisper images? Thanks.

How do you reference image files in jsp which becomes a portlet ?

My portlet is a servlet managing jsp pages. In each of the jsp s, there are image files (*.gif) being referenced. I have placed the image files in .../public_html/WEB-INF/images/ in explorer. In my jsp, I am referencing the image file as
src="WEB-INF/images/help.gif"
On deploying my portlet, the image is not being picked up by the portal. Also, on moving the image and modifying the reference to it, I am still getting the same problem.
Can anyone advise, for my portlet to display the image correctly,
1) where should I place the image files ?
2) how should the jsp code reference it ?
Cheers,
Tara

Hi,
The behaviour you are reporting is an expected behaviour. If you want to include images in your JSP, you need to specify the complete absolute URL to the image on the midtier as only then can the portal invoke that image.
Actually, when you specified the relative URL
WEB-INF/images/help.gif, Oracle9iASPortal actually looks for the image help.gif in the directory structure WEB-INF/lib at its end. As no such file exists, the images are not rendered onto Oracle9iASPortal page.
So you got to use the following workaround,
Assuming your provider name is "temp" (deployed using temp.ear) & the image name is "help.gif" which is stored in the htdocs folder inside temp. This image is invoked by help.jsp
You can get the absolute path of this image as follows:
Request URL is : http://<host>:<port>/temp/providers/temp
Request URI is : /temp/providers/temp
So, Base URL = http://<host>:<port>
Servlet Path is : /temp/htdocs/help.jsp
Truncating the Servlet Path to /temp/htdocs & appending this to Base URL should give you
http://<host>:<port>/temp/htdocs
which is the directory that contains your image. add image name to this URL to get the absolute p[i]Long postings are being truncated to ~1 kB at this time.

Hey need help reading images using java bean

How can I add an Image to a jsp from different paths???

Hi,
I am trying to include an image to my jsp from a directory which is not located under my jsp's directory. In other words, is it possible to put my jpeg file whereever I want in my C folder and still be able to add it into my jsp?
Thanks,
Alex

That is not quite right. The image must be in a directory that is under the web server's view. JSP has nothing to do with images, the browser loads images separately after parsing the HTML results to find out what images it has to load. The images must be in a place that is servable by the web server being used.
If you were just using Tomcat as a web server, then you would have a web application directory "myapp". The images need to go under "myapp" or in any subdirectory, except the WEB-INF directory, which is a special case.

Crystal Report Images Not Showing - JSP inside /WEB-INF folder

Hi Experts,
I am using Crystal report for Eclipse and also using Struts2 and tiles framework combination.
The problem is when viewing the report all I've got is red X on all images and the graph image also not showing. This is when I use tiles and my jsp is inside the web-inf folder.
This is my struts link: href="s:url value='/report/reportOpen.action?report=1'
I've checked that the path to the viewer generated HTML is not correct. see code below.
src="../../../crystalreportviewers/js/crviewerinclude.js"
But when I test to access a simple jsp viewer that resides on the web root folder, this works fine but of course this is not what I want to have. I need to have my banner and menus on top of the report page (using tiles)
This is my jsp link: href="s:url value='/ReportViewer.jsp?report=1'
Viewer generated HTML below.
src="crystalreportviewers/js/crviewerinclude.js"
This might be a common problem and that you can share to me your solution.
Note: I removed the script tags because I can't submit this entry.
Thank you in advance,

Crystal Report Images Not Showing - JSP inside /WEB-INF folder

Hi Saravana,
After a few experimentation from your idea i was able to figure out the problem and now it is working.
I don't have to copy the folder to where my jsp resides but still maintains it in the root location: web/crystalreportviewers
The changes should always be in web.xml.
1st: change the crystal_image_uri value to ../crystalreportviewers
2nd: change crystal_image_use_relative value to "web"
Change to "web" instead of webapp because that is what I named my web root folder.
<context-param>
 <param-name>crystal_image_uri</param-name>
 <param-value>../crystalreportviewers</param-value>
 </context-param>
 <context-param>
 <param-name>crystal_image_use_relative</param-name>
 <param-value>web</param-value>
 </context-param>
Thank you. You showed me the way on how to solve the 3 day problem.
BTW, my next problem is when clicking on any buttons prev/next/print/export, I got this error HTTP Status 404.
Well, at least for now I can view my initial report. I just need to figure out the next issue and with the help of the great people here in the forum.
Thanks a lot.
Regards,

How to upload an image from servlet/jsp into server from clients machine?

can anybody send me the code to upload image from client to server using servlet/jsp.
i'm using tomcat server.

You can use the [Apache Commons FileUpload API|http://commons.apache.org/fileupload/] to upload files using Java.
Here is a Filter example which uses the FileUpload API to process the request and stores the regular request parameters back in the ParameterMap of the request and puts the uploades files as attributes of the request: [http://balusc.blogspot.com/2007/11/multipartfilter.html] Just define it once in web.xml and you can continue writing the servlet logic as usual.

Upload Image Using JSTL

hi,
Can anyone please help to Upload the Image using JSTL please give me the link of sample application. Or if anyone knows having a custom tag and JSF.
Thanks.

See the post (this page) on " Storing documents in Database using JSP"
The last post includes code for a servlet which uploads a file to the server, which I think is almost exactly what you're after.
