Upload/download image into Mysql

Hi there,
I'm trying to place an Image object into a mysql database, and then also have the ability to download it. I'm using a BLOB column type to store the image. I dont really know how to do this, i've looked at http://forum.java.sun.com/thread.jsp?forum=48&thread=446603 which is kind of relavant but I just want to load the image.
Any help would be cool,
Steve

That is exaclty what he is doing, if you notice
dPhoto = new ImageIcon(b);he has created a new image that he can now display in a swing gui

How can you upload an image to MYSQL using php?

Ok this is a joint thread with one of my other ones because no one else was posting on it, so I did not get what I needed, so, How can you upload an image to mysql so when some one logs on to my site, they see or can upload there own avatar, now there are loads of problems with this, 1) many people don't know how, 2) It's not every day you try to encode a image into mysql, 3) Letting people upload images into mysql can cause traffic problem with people trying to log in. So that's it.

Uploading images into MySQL is a bad idea, for more reasons than you mention. You should store the images in a directory on the server instead. But if you want to learn the hard way, here is the method:
The mysql data type must be blob.
The form enctype must be multipart, like this: enctype="multipart/form-data"
The form input field myst be type file, like this: <input type="file" name="upload"/>
Here is example code that prepares the variable $photodata to be inserted into the database.
$uploadfile = $_FILES['upload']['tmp_name'];
$photoname = $_FILES['upload']['name'];
$uploadtype = $_FILES['upload']['type'];
if ($uploadfile != "") {
$tempfile = fopen($uploadfile, 'rb');
$filesize=filesize($uploadfile);
$width=getimagesize($uploadfile);
$widthx=$width[0];
$heightx=$width[1];
if (($widthx > 102) or (heightx > 135)){
$image_too_big = " but the image size was too large and was not submitted.";
} else {
$photodata = fread($tempfile, filesize($uploadfile));
$photodata = addslashes($photodata);

Problem in uploading an image into a CM repository!!

Hi All,
 I am trying to use the Fileupload element in JSP dynpage.
 My screen has the Fileupload element and a button.
 I want to upload an image into a CM repository.
 I have put <hbj:form id="myFormId" encodingType="multipart/form-data" > in my jsp page.
 The 'onClick' method is 'onLoadFile'.
 The following is my code:
public void onLoadFile(Event event)
 FileUpload fu =
 (FileUpload) this.getComponentByName("myfileupload");
 if (fu != null) {
 // Get file parameters
 IFileParam fileParam = fu.getFile();
 // Get the temporary file name
 File f = fileParam.getFile();
 String fileName = fileParam.getFileName();
 // Get the selected file name
 String ivSelectedFileName = fu.getFile().getSelectedFileName();
 try {
 int len = (int) f.length();
 byte a[] = new byte[len];
 FileInputStream fin = new FileInputStream(f);
 fin.read(a);
 String FileContent = a.toString();
 IPortalComponentRequest request =
 (IPortalComponentRequest) this.getRequest();
 com.sapportals.portal.security.usermanagement.IUser user =
 (com.sapportals.portal.security.usermanagement.IUser) request.getUser().getUser();
 IResourceFactory factory = ResourceFactory.getInstance();
 IResourceContext context = new ResourceContext(user);
 RID rid = RID.getRID("/documents/test");
 IResource resource = factory.getResource(rid, context);
 if (resource != null) {
 ICollection parent =
 (ICollection) ResourceFactory
 .getInstance()
 .getResource(
 rid,
 context);
 String out = new String(FileContent);
 ByteArrayInputStream data =
 new ByteArrayInputStream(out.getBytes());
 IContent content =
 new Content(data, "text/html", data.available());
 IResource fileResource =
 parent.createResource(fileName, null, content);
 } catch (Exception e) {
 ..... REMAINING CODE...
I uploaded abc.jpg (size: 2KB), then, an image file with the same-name is being created in the /documents/test folder but the size is 10Bytes only. I am not able to see the image too.
Can any1 help me plzzzz??? Would appreciate any kind of help.
Thanks in advance.

Sai Krishna.

I would guess that this is because of the way you try to read the file contents. Maybe you should add some debug statements to find out what you're realling setting as content. It's certainly not KM's fault.
The following sequence of statements looks wrong:
nt len = (int) f.length();
byte a[] = new byte[len];
FileInputStream fin = new FileInputStream(f);
fin.read(a);
String FileContent = a.toString();
IPortalComponentRequest request =
(IPortalComponentRequest) this.getRequest();
com.sapportals.portal.security.usermanagement.IUser user =
(com.sapportals.portal.security.usermanagement.IUser) request.getUser().getUser();
IResourceFactory factory = ResourceFactory.getInstance();
IResourceContext context = new ResourceContext(user);
RID rid = RID.getRID("/documents/test");
IResource resource = factory.getResource(rid, context);
if (resource != null) {
ICollection parent =
(ICollection) ResourceFactory
.getInstance()
.getResource(
rid,
context);
String out = new String(FileContent);
ByteArrayInputStream data =
new ByteArrayInputStream(out.getBytes());
IContent content =
new Content(data, "text/html", data.available());
Why don't you just pass the FileInputStream into the Content object's constructor???

i need ur help,we hav online site .Please don't use these juvenile abbreviations. It's impolite when you're asking for assistance not to make the effort to spell out all of the words. Moreover in a forum with an international readership the use of standard English will reduce the possibility of confusion.
I presume that your file upload is being placed in a different directory from that which you were expecting. I would suggest logging all paths (specifically filename) to see if this is an unexpected value.
Please explain further what you mean by "local" - is this a stand-alone application, or merely running a copy of the server on your local machine and doing the transfer (via the browser) to that? Are there any other differences such as the browser used?

Uploading a file into mySQL database?

Hello, everybody.
Can anyone give me a code snippet or at least a hint, how could I upload a file into the BLOB field of mySQL database using JSP webpage? How do you generally store uploaded files on the server? If anyone could suggest a good algorythm of saving the files in the server's file system and saving only their URLs in the database (this was my initial idea), I would be ready to accept this as well.
Would be appreciated for any help.

Hi
Fou uploading the files from client site to server user the utility given by oreilly Go to this site and down the code for uploading the source code for fileupload
For writing this code to database use this code
code
import java.sql.*;
import java.io.*;
class BlobTest {
     public static void main(String args[]) {
          try {
               //File to be created. Original file is duke.gif.
               DriverManager.registerDriver( new org.gjt.mm.mysql.Driver());
               Connection conn = DriverManager.getConnection("jdbc:mysql://agt_229/test","manoj","manoj");
               /*PreparedStatement pstmt = conn.prepareStatement("INSERT INTO BlobTest VALUES( ?, ? )" );
               pstmt.setString( 1, "photo1");
               File imageFile = new File("duke.gif");
               InputStream is = new FileInputStream(imageFile);
               pstmt.setBinaryStream( 2, is, (int)(imageFile.length()));
               pstmt.executeUpdate();
               PreparedStatement pstmt = conn.prepareStatement("SELECT image FROM testblob WHERE Name = ?");
               pstmt.setString(1, args[0]);
               RandomAccessFile raf = new RandomAccessFile(args[0],"rw");
               ResultSet rs = pstmt.executeQuery();
               if(rs.next()) {
                    Blob blob = rs.getBlob(1);
                    int length = (int)blob.length();
                    byte [] _blob = blob.getBytes(1, length);
                    raf.write(_blob);
               System.out.println("Completed...");
          } catch(Exception e) {
               System.out.println(e);
end of code

But I failed to store webcam snapshot. I captured that image on Panel component.I converted that image to ByteArray. Now I want to save that image into the database. Please help me in this regard.
thanks in advance.

Uploading & Downloading Files into DMS Server using Web Dynpro Java

Hello Friends,
 I want to Upload a file from Portal to Document Management Server and to Download a file from Document Management Server to Portal, In short, I want to give the user the facility to Upload a File into DMS Sever via Portal and also to download the file from DMS Sever via Portal.
Can anybody give me a Input for the same from Both Java Development End as well as ABAP End, more inputs are required from ABAP end, since i have a very less ABAP Experience on working with DMS. Few Questions i have in my mind?
1. How to actually access the file contents with the help of Document Number?
2. With the help of Doc-Number we can extract the file from DMS sever but to provide a option for downloading in portal, the RFC should convert the File Contents into X-String or is there some other way?
+3. While Uploading the Data should be given in Which format to RFC? Are there any limitation with respect to size or formats. Is there any Standard RFC i can use directly in WD4 Java application to upload the file into DMS Server and which will return me the Document Number? +
Please give me your valuable inputs.
Thank You.

Now, I am able to download the File in Portal via my WD4 Java Application from DMS Server by passing the Document Number, but I am facing the problem in downloading the PDF files, Its not working for PDF files. Please give me inputs for the same.
Thank You.

HI,
Thanks for reply.
I am able to download the file From DMS server but I am still not able to Upload the File to DMS Server via Portal. For Download also it is working for all file formats but not for PDF any specific reason for the same.

Difficulty downloading images into iphoto 11

I am unable to import a load of photos into iphoto11. I've tried rebuilding my library using iphoto manager and importing via Image Capture as well. When I click import all I get the message "cannot import photos because there was an error downloading an image”.
When I try importing one-by-one I get the message “The file is an unrecognized format” although it’s a jpeg .

To anwser the two questions you asked-
1. How can we delete the entire import and start over? : You may select all media in Elements Organizer grid (which he imported from iPhoto) and hit Delete key
2. What is the correct way to move these images into the elements organizer? : The correct way is what he already did. Actually the folder naming convention is same as that of iPhoto. If you see the package contents of iPhoto Library, these folders can be seen there as well. When importing in Elements Organizer, it creates a copy of the iPhoto folder structure and then imports in the catalog.

Need to Upload the image into XMII server from a desktop

Hi,
Can anyone let me know how to upload the image from my laptop on to the server which i should be using in my pages. I tried using Image Loader and Image Saver. But it lead me no where. Is there a detailed documentation for this ?
Thanks for your help in Advance.
Regards,
Deepthi lakshmi.A.

Hi Deepti,
Could you give some details on what you are trying to achieve.
Is this a use case scenario where images need to be uploaded by a handful of people using some web UI?
or
Is this a use case scenario where you wish to upload images from the harddrive of absolutely any user?
The reason for my questions is as follows.
If you wish to allow some high-level (technically savvy) users the ability to upload images to be shown in dynamic content for remainder of the public, you could, in theory, set up a network directory that xMII is able to see. These High-Level users could drop their images in the folder and specify the path in a text box.
You could go one step further and use Get Folder List action from within an Xacute transaction and display the list of images in this folder on a web UI. Users could pick the image from the list and "Bob's your Uncle!".
Hope this helps,
Cheers,
Jai.

How to upload/download file into/from blob column in ADF/JDev 11g.

Hello to all.
I found demo from Kuba user on that page: http://kuba.zilp.pl/?id=1
But that demo is for release 10g and too complicated for me for this time (I'm fish in Jdeveloper).
I can create some simple table view (of form view) with oracle connection with table with blob data.
Blob column will content doc/xls/pdf ...etc.
Now I can add two buttons for download and upload.
What I have to do in next time?
Is it possible to use some component or something?
Thank you
Ben

I was able to accomplish downloading from a blob, but I'm trying to dynamically set the ContentType.
As the table may contain different types of files, I'm setting the ContentType to #{row.Fileext}, where Fileext is set in SQL select as follows:
pseudocode: get file extension, and set the content type based on file extension.
sql select :decode(substr(fdv.file_name,instr(fdv.file_name,'.',-1,1)+1),'log','text/plain; charset=utf-8','xml','text/xml','xls','application/vnd.ms-excel','tif','image/tiff','jpg','image/jpeg','unknown')
I rather use a fuction/method, and tried the following instead:
ContentType = #{backingBeanScope.backing_processReqs.FileAttachContType}
where FileAttachContType =
public class ProcessReqs {
public String FileAttachContType() {
// code to substring filename for extension and decode values
return strContType
But I get the following error:
Error 500--Internal Server Error
          javax.el.PropertyNotFoundException: The class 'sunrider.reqpoportal.view.backing.ProcessReqs' does not have the property 'FileAttachContType'.
               at javax.el.BeanELResolver.getBeanProperty(BeanELResolver.java:547)
               at javax.el.BeanELResolver.getValue(BeanELResolver.java:249)
               at javax.el.CompositeELResolver.getValue(CompositeELResolver.java:143)
Ideas?
PS: Kuba, I've been trying to get to your blog all day, and it would just time out.
Thanks everyone in advance!

Uploading Safari images into 'Blackboard' doesn't work.

I am using an iMac G5, OS X (10.4.8), 2Ghz PowerPC with 512 MG of RAM.
I am able to successfully create .html files with various programs (Nvu, Dreamweaver, Mozilla,) and I can open those documents and see the images in them in my default Safari browser (as well Explorer, Firefox, Mozilla,). I USED to able to upload those documents successfully into the 'Blackboard' program my college uses. Here I can't be helpful: I did something -perhaps changed my browser from Netscape Navigator to Safari, but I can't guarantee that's the problem- so that the uploads show the text but no longer load the images. When I open the documents in the Blackboard program, the images don't show as broken, they show as question marks in a small blue square in the center of the missing image.
I have tried the Blackboard help site, and all the image-loading recommendations I see on this forum. I've tried going to 'Safari> Preferences> Appearance> Display images when the page opens' and making sure that box is checked. I've tried finding 'Safari> File> Publish as> and making sure images are published, but I can't find that option on my Mac. None of the tech support at school can solve the problem -though the process supposedly works just fine on a PC. I have struggled with this for months, and since I teach art history and need to show images, it is making my life miserable. Any help would be much appreciated.

Thanks for the rapid response! A pity I don't have the language to be of more help.
First, 'Blackboard.edu' is a service institutions of education subscribe to. Faculty users publish their class webpages, and can keep those inhouse or make them available to the www. So, I've been publishing web pages (in house) for my classes for years. This year I've run into problems with getting my .html documents to load the images contained in them. I do believe my colleagues have uploaded my documents successfully onto their Blackboards via PCs, leading me to believe this is a Mac problem . . .
Someone suggested this was a browser problem, so I kept trying different default browsers, searching their preferences for any boxes that needed to be checked to allow images. Each time I upload I am told the upload was sucessful -I get no error messages- and each time the images don't load.
I defaulted to Safari and did as you suggested, and there was a slight change. Instead of the blue-box question mark, the image title was displayed, but still no image.

I can't upload images into CS6 due to a plugin error that hasn't occurred before.

As the title says, I keep getting an error when I try to upload an image into CS6. It hasn't done this before, and I don't know what to do. I've even tried opening my previous images I've used in works before in CS6 and they are all greyed out as well. I really need some help, any is appreciated. Thanks.

You can't open the image file in InDesign.
Go to File-->Place and place the image file in InDesign

My iPad will accept downloaded images from my camera, but will not allow me to move the images to a thumb drive, with the message that those devices require too much power for the iPad.

Using an older, second-issue iPad, I can download images into it from my camera. I cannot move them out of the iPad into a thumb drive. The message I receive is that the thumb drives require too much energy to make the transfer. What can I do?

Thats how its designed. in order to export your images or videos, the best method might be by connecting the iPad to your computer, or directly to the thumb drive connected to your computer, not to the iPad. Then is as simple as drag and drop. The other method could be sending them by email or uploading via a cloud service but that will take more time do get it done.
Hope this helps.
