CF9 - display binary from database as inline PDF

Hello, everyone.
Is it possible to get binary data from C/BLOB and display it as an inline PDF? Not to download, just embed it in HTML/CFML?
Thank you,
^_^

You should be able to have it download using cfheader

<cfheader name="Content-Disposition" value="inline; filename=Test.pdf">
<cfdocument format="pdf">
<cfoutput>
#tobase64(myquery.PDFhtml)#
</cfoutput>
</cfdocument>

Display Images from Database

Hi all,
I require to display images stored in database along with textual description of it on a JSP.
The image file should not be stored intermediately on file system (i.e w/o using img HTML tag)
It is a typical shopping cart appln. where images are fetched from database and the associated description is displayed along side.
Please note that it is the case of Mixed content types(text and binary data).
Thanks and Regards

Like "Breakfast" said, you can do this with a servlet that retrieves your images from a database....
if you create a servlet to do this, you would have a generic servlet which retrieves a picture from a database based upon a key which could be a picture name or number.
Lets say the file is out there in the database as a BLOB or Binary Image... you could have this kind of code in the doPost(HttpRequest req, HttpResponse res) or doService(HttpRequest req, HttpResponse res) method.
The table holding the image has at least two columns one called IMAGE which holds the binary image and the other called FILENAME. If the connection to the DB is already open, you do something like this.
String fileToGet = (String)req.getParameter("FILENAME");
rs = conn.createStatement().executeQuery("select from IMAGE_TABLE where FILENAME='" + fileToGet + "'");
if(rs.next())
InputStream in = rs.getBinaryStream("IMAGE");
res.setContentType("image/jpg"); // or whatever type of file it is.
ServletOutputStream sout = res.getOutputStream();
int c;
while((c = in.read()) != -1)
sout.write(c);
in.close();
sout.close();
This should write your image to the response output of the servlet.
Now, where you want your image, you put.
<img src="/servlet/ImageServlet?FILENAME="thefileIwant">
This should do what you want... Use your favorite pipe copy method to get the input stream to the output stream. If you are worried about overhead and scaling like "breakfast" said (it CAN be a problem in high access sites), then you can add an image caching scheme and get really complex.... But this is a rough idea on what to do.
Hope this helps.

Displaying image from database in report

I need to include a picture (company logo) in numerous reports. This logo will be stored in an MS SQL Image field in a table (this bit I have already sorted out).
What I'm wondering is, what is the best way to retrieve this image from the database? Do I just include it in the view the report runs off? I'm hesitant to do this, as the view may return back hundreds of records, which means (I think) it will be sending the image along with it hundreds in time.
In short:
1) What is the best way to pass an image to a report.
2) If I include the Image field in a view which returns back hundreds of line, will the image be returned also hundreds of time, causing network congestion/performance issues?
3) If so (2), is there a way of sending the image only once, no matter how many rows are in the returned view?
Thanks.

Hi Shanon,
We can display the image by making it a local copy on your machine.
If it is possible to get the image saved on local copy.
If we place the image in detail section then it would return one record.
As the image is from Database, so it would hit the database very time when you refresh the report and place it in Report Header or report fotter.
So, place your logo as an OLE object in report and would reduce processing time.
Regards,
Naveen.

Help with displaying info from database+asp

How can I display info from a database so that it is
formatted into rows in a table
here is an example of what I would like
http://www.westerveltcollege.com/new/programs/bus_admin_computers.html
(it is the section that show the course content)
I know it has been code into the table but how to do this
dymanically
hope that makes sense to someone ;)

To do it properly you would set up two tables. The first
would contain the
topics and be something like this
topicID
topicName
Then you would have a second table that would hold the
content like this
contentID
contentName
topicID
The last field links this table to the topic.
To display them you would link the topics into a master list,
and then pass
the topicID to the page displaying the content and use the
topicID as a
filter on the content table.

Display image from database with jspSmart

Hi
I have successfully uploaded and saved images into oracle(8.1.5) table DATA_TYPE(dtid number, iconname varchar2(30), icon blob). When I try to display a specific icon in my browser, I get "javax.servlet.ServletException: General error" at:
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);
My code looks like this:
imgModifyDataType.jsp
<%
ResultSet myResultSet = null;
Statement myStatement = null;
Connection myConnection = null;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
myConnection = DriverManager.getConnection("Jdbc:Odbc:Te","te","te");
String iconName;
String pDTID = request.getParameter("dtid");
String mySQL = "Select iconname, icon from data_types where dtid=?";
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);
pstmt.setString(1,pDTID);
myResultSet = pstmt.executeQuery();
iconName = myResultSet.getString("iconname");
myUpload.initialize(pageContext);
myUpload.downloadField(myResultSet,"icon","application/x-msdownload", iconName);
%>
I call this JSP from another JSP like this:
<img src="imgModifyDataType.jsp?dtid=<%=pDTID%>">
If we cannt display image with the help of another jsp like this then please guide me how to modify the imgModifyDataType.jsp to a servlet because I have never worked in servlets.
Please help

How to display data from Database individually??? Anyone can help ?

HI,
i i had select a row of data from database using ,
/* Query * From Table RESOURCEORDER where po = selected no and project = selected project */
     public ResultSet getAllData() throws SQLException
     getConnection();
     Statement stmt = conn.createStatement();
     ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
     return rs;
After that , how do i display the data individually ?
Eg select data is ('projectA','7891203-1', '10-4-2005','lcd',2000,'121-45217-8','electrical','pending','donwong')
i want to display them individually, like this in a page
Projectname: /* should display the Project A*/
P.O no:
Date:
Order:
Cost:
Acc no:
Type:
status:
Orderedby:
Can anyone help ? cos i'm new to JSP ......Thanks alot!!!!!
Regards,
khim

I assume PO being a unique key, will always return 1 row from db.
public String[] getAllData() throws Exception
getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM RESOURCEORDER WHERE PROJECT = '" + getSelProject() + "' and PURCHASEORDERNO = '" + getPo() + "'" );
String [] returnValue = new String[9];
while(rs.next())
returnValue[1] = rs.getString("colname");
returnValue[2] = rs.getString("colname");
///and so on
return returnValue;
}Once you get that you could individually view it by setting a loop to run through the returned array.
Hope it helps

Convert pdf from database system to pdf creator with our LOGO possible?

We work in our company with a data base programme and when we creat a pdf with the info of these programme we want our LOGO automaticly intergrate in these new PDF.

1. What software currently creates the PDF from database info?
2. Is this software on each user's computer, on the database server, a web server, or somewhere else?

Return Binary from Database

I am writing a program that allows a user to upload a file and store that file in the database. That works great. Getting that file to display correctly is not working as well.
I store, along with the binary data, the file type i.e. image/gif, application/pdf etc.
When I send the Binary Data to the client I use the method setContentType to set the content type to the correct type.
This works great for images and some other files (doc, xls) But will not work for exe, pdf and most others.
I want to know how to set the correct http headers that will allow the browser to think it is downloading the correct type of file as well to have the correct filename.
Any suggestions would be great.
Colin

Hey There.
Here is a snippit of servlet code that I have used to stream PDF's to a client browser. Works like a charm. I think your main problem might have been the ContentType, along with stream objects used.
Give it a try, and let me know how it works.
Regards,
Victor VanHerk
final static String CONTENT_TYPE = "application/pdf";
final static String document = "d:\\test.pdf";
HttpSession     session     = request.getSession();
// reset the response
response.reset();
response.setContentType(CONTENT_TYPE);
try{
     // Get streams
     FileInputStream fileInputStream = new FileInputStream(document);
     ServletOutputStream servletOutputStream = response.getOutputStream();
     // Init byte count and array
     int bytesRead = 0;
     byte byteArray[] = new byte[4096];
     // Read in bytes through file stream, and write out through servlet stream
     while((bytesRead = fileInputStream.read(byteArray)) != -1) {
          servletOutputStream.write(byteArray, 0, bytesRead);
     // Flush and close seat
     servletOutputStream.flush();
     servletOutputStream.close();
     fileInputStream.close();
}

Displaying image from Database with php

Hello everybody,
I'm working on a website that displays videos courses and tutorials as my final project
and I'm working with "Flash builder 4" the database with mySQL and the application server with php
Basically, the goal is to display a datagrid that shows the manager of the website in column all the information stored on the "Course" table
the structure of the table is :
Course (id,img,src,title,description)
-id : primary key
-img : path to a photo of course {for example picture of JAVA}
-src : path to the playlist file {xml file}
-title : String
-description : String too
I already succeeded to display all these contents on a DataGrid, but not with the image, I couldn't display an imageon its column using the path stored on the database, I used a DataRenderer to do that, and here is my code for Renderer and the DataGrid.mxml
CourseGrid.mxml

Result :
Problem :
How can I access to the path of the image, I tried to write "data.img" instead of "data" as img is the name of the column in the database that stores the path but it wasn't successful.
I know that it not complete statement "data" because "data" is a reference to what the DataGrid provides of information that gets from the (CreationComplete) event.
Question :
- Can you please help me with this so I can complete displaying images by accessing to what is on the column in tha DB so I can manipulate my datas that is stored there ?
==> I still have some questions about the buttons to update and delete datas fomr the DataGrid, but, until now I need to access successfully to the photo and display it
Thank you,

Anyone that can help me with this ?
Please, try this with me, I'm asking Flex developpers this might be easy for you !
It's just question of how to access the string stored in the variable "data", when I used XML I just type the path to the repeated element like this :
XML file :
XML File
<parent>
<child>
<repeated_child></repeated_child>
<repeated_child></repeated_child>
<repeated_child></repeated_child>
</child>
</parent>
I used a Model as a reference to the xml file
and an arrayList as a container of the repeated child
I just write in the code "data.parent.repeated_child" to access the text in the "repeated_child"
and here is the code, that I implemented to generate videos from xml file to display a video play list
Video Playlist code(extract from XML file "data.xml")
<fx:Declarations>
<fx:Model id="model" source="assets/data.xml"/>
<s:ArrayList id="products" source="{model.video}"/>
</fx:Declarations>
<mx:List dataProvider="{products}" labelField="title"
change="list1_changeHandler(event,List(event.currentTarget).selectedItem)" x="103" y="77" height="350" width="198"/>
That was my goal to do that with the database.
Please help me
If you have other solution I still need it.
Thank you,

ADF: Display image from database

Hi,
I've found a number of threads addressing this issue, but none that have solved my problem as yet. I'm trying to display an image from a database column in JDev 10.1.3.2.0. I've found an article in the Help that sounds like it's describing exactly what I need:
To insert a databound image control into a form or panel: In the ADF Swing project, open the Java Visual Editor on the desired data panel or form. From the View menu choose Data Control Palette to open the palette. In the Data Control Palette, drag the attribute you want to bind to the image control into the open form or panel. From the Add Child popup list, select JUImageControl. JDeveloper adds code to the class file to bind the JUImageControl to the attribute
The problem I'm having is that this doesn't bear any relation to what I can see. I'm presuming that the Java Visual Editor is the design tab of the jsp page editor, as this is the only visual editor I can find. If it isn't, that would explain why this doesn't work... When I drag my attribute, I have to select what type of item I want it to be. I can't find an Add Child popup anywhere.
I have a horrible feeling that this is a very stupid question, but I'm completely stuck.

The help-text you found refers to an ADF-Swing project, not a web application with JSP's. This post: How to display the content of a BLOB column in a ADF/BC pages ? shows you how to do it with ADF Faces.

Store and Display Image from Database

Now that MySQL is working (woo hoo!) with JSC, I have a couple of questions for any experts out there...
1. How would I perform an image or other file upload from a browser?
2. How would I retrieve and display an image from a db on a jsp page?
Thanks for any help.

Craig, I think I have a simpler way to load an image on the page, although for the time being I'm not retrieving from a database, but from the file system. The problem is that I'm not getting the pages to load continuously with new images. At some point it apears that the session gets clogges and can not load new pictures. I'll try to include the page bean code just below. This time I'm not adding the "code" tags because I haven't being successful with that. If you have problems , please, contact me at [email protected].
The core of the code is in a couple of button_action methods.
If you need, I can give access to the http server where this is running.

Displaying data from database into mxList

Hello Flex Developers!
I am getting back an Array Collection with Objects inside from the database. I would like to display this in the mxml portion of my application using the mx:List control. When I put in something like:
<mx:List id="myId" dataprovider="{acFromDatabase}"></mx:List>, wrapped in a Canvas, inside of a tab navigator, I am getting back the array of objects and displayed something like this: object Object. How can I go into this object and display it within the List control? The object has values like name, date, title, etc?
Thanks in advance!

@K4Flex,
you can make use of an itemRenderer and include what all controls you require in your itemrenderer for display.
You can post some of your code so that I will let you know what I am saying.
Thanks,

Alternative ways of displaying image from database?

hi - I'm working with some legacy/inherited/already-written Forms that just use block triggers to 'select values into :Fields..' to populate the text boxes on the canvas.
Whenever I've managed to display db-based images before, it's always been on blocks that are based just on the table, and Forms shows the image okay.
These forms I'm using at the moment though aren't based on tables, they just get populated from the trigger.
I don't believe you can select into a blob/image, or at least I haven't been able to get that to work.
Are there any alternative ways of populating an image place-holder, with a blob field from the database? (other than using a table-based block)??
thanks.

May be you can separate the image item to a DB block with primary key of the table and create a relation between two blocks. So when the first block is populated through trigger, it would fetch the image on 2nd block automatically.

Displaying image from database

Hello. I have this problem if anyone can help. I have an image inserted into a MySQL database. But when I try to display it using JSP I get a screen full of funny characters and do not display. The code I use is below.
String sql2 = "Select image1 from images";
ResultSet rs2 = stmt.executeQuery(sql2);
if(rs2.next())
InputStream in = rs2.getBinaryStream("image1");
response.setContentType("image/jpg");
ServletOutputStream sout = response.getOutputStream();
int c;
while((c = in.read()) != -1)
sout.write(c);
in.close();
sout.close();
I tried using the code below, but that don't work either.
%>
<tr>
<td><img src="<%= rs2.getString("image2") %>"></td>
</tr>
<%
What am I doing wrong here? Is it better to grab the image straight out of a directory? If so, how? The image would be on the Tomcat4 server in the root directory.

When a html page is downloaded to the client, each image, css include, *.js include etc.. are fetch one at a time. So you would want to write a servlet that is mapped to something like /database/image/name.jpg and this servlet would be responible for pulling the image from the database, setting the proper MIME type and writing it to the client.
In your case, you are writing the image content to the client within the jsp page. This explains the char's you see within the page.
Things you should do:
Create custom servlet which will pull the images from the database.
map the servlet to what ever patteren you like. (web.xml file you would edit)
Set the mime type and write the image.
I hope this is of help.
