Display image file from outside web

Hi.
My application is in c:\projects and I need to display images from d:\Photo.
Can anybody tell me how to do that?

You could always make a servlet which loads the image from that directory.
<img src="/servlet/imageServlet?image=myImage.jpg">
Have the ImageServlet load the file from disk, and send it out via the ouputstream.
Apart from that no. Web applications can only access directories under their context. Accessing anywhere else would be a security issue.

How to display image file from the link in the field

Hi all,
I have a column where it keeps the link of the image files reside. The link will be in the server such as \\server\picture1.jpg
I have try to code in Read_Image_File('\\server\picture1.jpg', 'ANY','OM_ITEM.ITEM_URL');
But I was encountered error run, ORA-01465: invalid hex number.
Any one please help me. Thanks.

There are tons of informations missing here, for instance (but not limited to) the exact forms version you are using (note: 10g is not a version, but 10.1.2.0.2 is). Without Version informations a correct answer is not possible
You might want to go through the links from the Announcement entitled "<a href=http://forums.oracle.com/forums/ann.jspa?annID=432>Before posting on this forum please read </a>" which contains links to the documentation and instructions on how to post proper questions for example.

How to display a dynamic image file from url?

Hey,I want to display a dynamic image file from url in applet.For example,a jpg file which from one video camera server,store one frame pictur for ever.My java file looks like here:

F.setSize(480, 240);
PlayJpg A = new PlayJpg();
F.add(A);
A.start(); // Web browser calls start() automatically

I only get the first frame picture for ever by my html.But the jpg file is dynamic.
Why?
Can you help me?

Hi,
Add this line inside your run() method, right before your call to repaint():
if (image != null) {image.flush();}Hope this helps,

Lately pdf files from the Web do not display properly; what is wrong and how can I fix it so I don't have to use IE?

I am a professor and frequently need to open pdfs of academic journal articles from electronic databases. Within the last two or three weeks, when I try to do this using Firefox, only the first page of the pdf displays and the rest are blank. In addition, a bar appears across the top with the message "This pdf file may not display properly." So I have had to switch to Internet Explorer to open the files and do my research. What is going on and how can I fix it so I can open pdf files from the Web in Firefox and have them display properly?

My question is simple - why would you put an application in production that has a lot of bugs? To replace a good and steady Adobe product? My customers will believe that I put a pathetic fallible form online. They are not sophisticated on computers so I just tell them to use IE. Ugh
I must agree with pgwebgirl!

Display image in Smart camera web interface

Hi!
I need some assistance with LV-RT.
What I have succeeded is to enalble the web server on NI 17XX camera and successfully displayed a VI with Image Display on it. I thikn I got the hang of it.
What I would like to know is there another way to display images on the camera web page. I really do not need the whole VI up there just an image and a string with serial number. One way I know would work is to write an image file to the system memory and then embed that image to the web page, but I am not sure that is the best solution as writing process takes time and it is not recommended to write too often to the program memory (am I right?).
So, is there some way to assign some object to say a memory bank and display it (without having to install the runtime maybe) on the page?
Thank you for your attention,
Mart

Hey Mart,
Going back to your original question; are you looking to stream images to a web page from your smart camera or simple see what your camera is seeing when you go to a particular site? Take a look at the sample project below. It is sort of a work around, but it posts an image to a web service. Essentially it snaps an image, saves it, and then posts the saved image to a web service. You will have to change the file path for the image, then build and deploy the webservice from the project view. Also, it would be beneficial to take a look at the webservice build specifications. The webbing to view the snapped image from your local machine would then be viewable from your web browsers at the address : "http://localhost/Stream_Service/ShowImag"
Let us know if you have trouble getting this example working. Also, perhaps another visit to what your end goal is would be helpful. What was it that you had working?
Hope this helps

I'm unable to print pdf files from certain web sites. I have just changed to Mavericks

i'm unable to print pdf file from certain web site. I just changed over to Mavericks.

You will need to access that PDF on your computer first, before you can print it — unless that PDF is corrupted, which occasionally happens. Your printer needs to be configured and working.
Default PDF web-browser plug-in in Safari, latest (Firefox/Chrome) also built-in.
Click on the remote PDF link to open in browser
On Mavericks, you will need to click through security challenges for the PDF
File menu > Print
Right-click on remote PDF file and then choose Download Linked File As...Open that file in /Applications/Preview.appFile > print
Adobe Reader 11.0.04 PDF plug-in
Same security challenges on Mavericks as first bullet
With PDF imaged in browser, either select print icon from the plug-in toolbar, or mouse over the bottom one inch of displayed document and you will see a printer icon in the popup toolbar. Use that.

Adobe 8 - Unexpected Corrupt or incorrect file type warning when viewing a PDF file from the Web

Hi,
On downloading a PDF file from my web site using Adobe 8 on the client machine I expect the file to open automatically however I receive encounter the "File Download" dialog. It has the following warning message: "The file you are downloading cannot be opened by the default program. It is either corrupted or it has an incorrect file type. As a security precaution, it is recommended that you cancel the download."
This issue did not occur within previously tested versions of Adobe Reader (e.g. Version 5.1).
On investigating the issue I discovered the factor that results in Adobe 8 failing to open the file automatically is the Content-Type = "application/pdf; Charset=utf-8". However, if I intercept the response and alter the Content-Type to contain only "application/pdf;" the issue on Adobe 8 does not occur.
I have even tested when the Content-Type contains an empty Charset (i.e. "application/pdf; Charset=") but this issue still occurs. In addition setting the Charset to other encodings (e.g. "ISO-LATIN-7", "iso-8859-1") the issue occurs.
QUESTION(s):
1. Why is it necessary for Adobe 8 when opening PDF files from the web to expect no Charset within the Content-Type?
2. If this was not an issue within previous versions of Adobe surly this is a bug?
Since I cannot ensure that the Response's Content-Type does not contain a Charset at all please can someone suggest either a work-around or more importantly a solution to the issue?
Please Note:-
1. Within Adobe, Edit -> Preferences -> Internet option it's compulsory for our users to have "Display PDF in browser" ticked!
2. We cannot prevent a Charset from being present within the Content-Type of the response sent to the client, hence this issue.
Many Thanks in advance,
Martin.

Bill,
This is exactly the same behavior I observed when I rendered a PDF stored in a database through a .NET page. If I chose to save it, it would open fine after the save, but if I chose to open it in the browser without saving it, I would get the error.
The problem was not with the PDF or Acrobat. It was with the way I was delivering the PDF. Putting the following code before my binarywrite fixed the issue completely:
Response.ClearHeaders()
Response.ClearContent()
Response.ContentType = "application/octet-stream"
Response.AddHeader("content-disposition", "attachment; filename=" + saveFilename)
where saveFileName is the name you want to give the PDF.
You can use 'inline' instead of 'attachment' above if you just want the PDF to open (no option to save first). You can also use 'pdf' instead of 'octet-stream' (not sure the difference).
The trouble seems to be that .NET puts some info in the header and/or content by default prior to anything your code says to write. If you don't clear this, IE has an issue with it. Other browsers seem to ignore it.
Bottomline is that this is an issue the website programmer needs to fix and is not something the user can fix by changing some setting(s).
I hope this helps.

I cannot display image (read from oracle BLOB field) on browser?

I cannot display image (read from oracle BLOB field) on browser?
Following is my code, someone can give me an advise?
content.htm:
<html>
<h1>this is a test .</h1>
<hr>
<img src="showcontent.jsp">
</html>showcontent.jsp:
<%@ page import="com.stsc.util.*" %>
<%@ include file="/html/base.jsp" %>
<%
     STDataSet data = new STDataSet();
//get blob field from database
     String sql = "SELECT NR FROM ZWTAB WHERE BZH='liqf004' AND ZJH='001'";
     //get the result from database
     ResultSet rs = data.getResult(sql,dbBase);
     if (rs!=null && rs.next()) {
          Blob myBlob = rs.getBlob("NR");
          response.setContentType("image/jpeg");//
          byte[] ba = myBlob.getBytes(1, (int)myBlob.length());
          response.getOutputStream().write(ba);
          response.getOutputStream().flush();
     // close your result set, statement
     data.close();
%>

Don't use jsp for that, use servlet. because the jsp engine will send a blank lines to outPutStream corresponding to <%@ ...> tags and other contents included in your /html/base.jsp file before sending the image. The result will not be treated as a valid image by the browser.
To test this, type directly showcontent.jsp on your browser, and view it source.

Help required with downloading files from inside WEB-INF folder

I am working on a web application and I have an upload script which uploads different files to a foler called 'uploads' . To stop users from accessing the folder content I have put it in the /WEB-INF/.
In my JSP file, I used to link to the uploaded files like this before for users to download them :
if(filesListIterator.hasNext()
files = (FilesBean)filesListIterator.next();
<tr><td><a target="_new" href="<%=files.getFileName()%>">"<%=files.getFileName()%></a></td></tr>
}I need to know how to alter the above link to make it access/download files from the /WEB-INF/uploads/ while still restricting direct access to the files.
Thanks

Anything under WEB-INF is not directly accessible via the browser/ client. You could try defining the JSP/ Servlet inside web.xml deployment descriptor and see if you can access the file from there.
I think a better way to accomplish this would be to keep the file outside WEB-INF , and use other techniques to protect the folder that contains the file - for example password-protection, or defining a .htaccess file and serving a 403 Forbidden error.

How to make a image file from Pre installed Mac osx ? "PLEASE HELP :("?

hey guys ..Thanks u for the time.
So i have this eMac which has crashed and i have got may hands on another eMac.. and it works
... the only problem is.. I can take my eMac to the working eMac to do Target Mode or any thing...
So Help me..
My question is .. Is there a way to make a .DMG image file from pre installed mac osx OR
Is there a way to may a recovery disc??

You can use Carbon Copy Cloner to copy everything from the working eMac onto the non-working eMac while the working eMac is running. If your eMac will still do target mode into the working one, you can download the above software, select the booted drive as the source drive, and your eMac's drive as the target, however it is possible this will not work.
When you say your eMac crashed, what exactly happened? It is possible that the hard drive in your eMac failed or is failing, so in order to get it running again you would need to replace the hard drive. On the eMac, this repair is somewhat involved, and you have to be very careful because it exposes the CRT, which has several areas which can be extremely dangerous to touch if not properly handled. CRTs retain a great deal of voltage, even when unplugged, sometimes for weeks, and they can give you a nasty shock if you touch them in the wrong place.
Also keep in mind that cloning from the working computer to the non-working computer will ERASE any data that you have stored on that eMac, so if you don't have it backed up anywhere, you may want to attempt that with target mode before proceeding.
Good luck!

How to Copy an Image File from a Folder to another Folder

i face the problem of copying an image file from a folder to another folder by coding. i not really know which method to use so i need some reference about it. hope to get reply soon, thx :)

Try this code. Make an object of this class and call
copyTo method.
import java.io.*;
import java.net.*;
import java.util.*;
public class FileUtil
extends File {
public FileUtil(String pathname) throws
NullPointerException {
super(pathname);
public void copyTo(File dest) throws Exception {
File parent = dest.getParentFile();
parent.mkdirs();
FileInputStream in = new FileInputStream(this); //
Open the source file
FileOutputStream out = new FileOutputStream(dest); //
Open the destination file
byte[] buffer = new byte[4096]; // Create an input
buffer
int bytes_read;
while ( (bytes_read = in.read(buffer)) != -1) { //
Keep reading until the end
out.write(buffer, 0, bytes_read);
in.close(); // Close the file
out.close(); // Close the file
This is poor object-oriented design. Use derivation only when you have to override methods -- this is just
a static utility method hiding here.

Why does Acrobat suddenly not work on my Mac (won't open pdf files from a web page), yet I can open them from my iPhone? Everything worked fine yesteray.

Hello:
I have a Mac running OS 10.8.5 and I use Acrobat Pro and Acrobat Reader. Today for some reason, any time I try and access a pdf file from a web page, it won't open. I get a blank window. PDF files already on my computer open fine and I can create PDF files from Word docs, but I can't download or view any pdf file from any web page. Strangely, PDF files on web pages open just fine on my iPhone.
I checked that both my copy of Acrobat Pro and Acrobat Reader are up-to-date. They are.
I checked that my copy of Firefox is up-to-date. It is. And nothing changed with Firefox within the last 24 hours.
I am a humble computer end-user. I am baffled as to why this would suddenly not work. I have not changed any settings, etc. Any help or suggestions would be greatly appreciated.

Thank you.
I checked your instructions you sent and as far as I can tell all of my settings, etc for Firefox (plugin updates and preferences) are correct but I am having the same problem.
However, everything works in Safari. I don't have time to attempt to diagnose why Firefox no longer works. I will just switch to Safari.
Many thanks.

Bug:Downloading pdf file from the web,file name in dialog box populates with incorrect file name

Hi Gurus
When downloading any pdf file from the web using adobe Reader X the file name dialog box populates with incorrect file name
compared to the saved file name of the document downloaded.
Clarity
1. Download any pdf file from the web
2. Click File, Save as note the populated File Name
3. Compare the populated file name with the saved file name of the documant yuo are downloading.
4. The file Name is incorrect...
Is there any work around on this issue?Can someone please help?..
OS:Windows7
Reader: Adobe Reader X
I've tried a couple of other versions and still get the same results...

Are you downloading the file (right-click, save link as), or just opening it by clicking it?
If the latter, then what happens is the file is loaded to the temporary internet files folder by IE and assigned a temporary name, which is then used when you're trying to save it.
You can test this out by going to File - Document Properties before trying to save and looking at the file's location.
