Dynamic images in JSP

Hi!
I would like to generate dynamic images in a JSP which I would like do an "include" in other JSPs across the site. The reason for this is we show many emails/ phone numbers on various pages and with the prevalence of spiders/ robots, it would be better to not have it as HTML text. I saw a couple of sites displaying them as images but they were PHP and ASP.Net sites. Any suggestions?
Thanks!!

Well... You could simply create 1 image per letter/number (this is done within a few minutes) and then code a function, which seperates the given string into chars and then creates HTML-code with the pictures.
There is an easier way, sure. But I don't know him :P. You know "Captchas"? The Codes you have to enter all over the internet to verify yourself as human and not as bot? If you google about ths code uses to create Captchas, you should be happy :)

Dynamic images with JSP

Hello,
I am using NetBeans to make a WebApp. I have an image to display on Page3.jsp that is generated during the navigation from the previous page, Page2.jsp. This image is a png file, and is unique graph generated for each visitor. Is there a simple way to display dynamically created images? I have searched for tutorials and asked my good pal Google but to no avail.
(FYI: At present, I am saving the images in a folder I have created beneath the 'web' folder, called 'web/images'. Netbeans asks me if I want to reload the image only after the previous, old image has been sent out by the server. I am producing and creating the image with the button_action method of Page2.jsp that then sends the user to Page3.jsp, where the image is to be displayed. Once the image is reloaded, I can refresh the web page and the correct image appears.)
Any help would be greatly appreciated.
Thanks,
Taivo

Although I have never implemented this, I know it is possible and I can point you in the right direction. If you already have the code to create the .png image, it shouldn't be too difficult to modify the image code into a servlet to serve nothing but the image (and leave rest of the html in place). Just as the page is writen to an output stream from the request for page.jsp (by the servlet created by the jsp parser), a request for an image can be handled by a servlet.
//this is in page3.jsp as plain HTML
<img src="/servlet/graph?user=aUser" />This servlet (graph.class) draws ths image, but instead of writing it to a file, writes it to the response stream.
Hope this helps,

Dynamic imaging in jsp doesnt work

 Hi,
 The following piece of code works in tomcat but does not work in weblogic. can
 anybody please help me with this.
 <%@ page contentType="image/jpeg" import="java.awt.*,java.awt.image.*,com.sun.image.codec.jpeg.*,java.util.*"%>

 g.setColor(Color.white);
 g.fillRect(0, 0, width, height);
 // Create random polygon
 Polygon poly = new Polygon();
 Random random = new Random();
 for (int i=0; i < 5; i++) {
 poly.addPoint(random.nextInt(width),
 random.nextInt(height));
 // Fill polygon
 g.setColor(Color.cyan);
 g.fillPolygon(poly);
 // Dispose context
 g.dispose();
 // Send back image
 ServletOutputStream sos = response.getOutputStream();
 JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(sos);
 encoder.encode(image);

 Thanx in advance.

 Thanx a lot.Just read your solution again. Didnt get it the first time .Its pretty
 interesting.I think i will opt for the servlets solution.

Create dynamic image, dump on server someplace and reference in JSP?

I was thinking about creating dynamic images and referencing them on a JSP
 (creating them is ok). I'm sure this is a pretty standard thing, but I
 don't know how to do it. Any ideas? I tried doing a search on the BEA
 support site (nice changes :>) but nothing very accurate came up.
 Thanks.


Assign an ID (e.g. 1234) to the uploaded file. You should abstract the store
 so that it will work on the file system or in the database.
 The JSP will include an image ref to that ID, e.g.
 http://www.myco.com/myapp/imageservlet?id=1234
 The image servlet will retrieve and stream the image. It has to set content
 type etc. You should also verify that the current user has access to the
 requested image if security/privacy is an issue.

Display image on jsp page

I have to display image on jsp page with some text output. This image is already saved at a location parallel to web-inf and is generated dynamically using a servlet. I have used img tag html to display the image. Other outputs are taking their values from database.
First problem is that image will be taking time to display in comparision of other outouts from database. I have to refresh the page to get imageon my page.
Second is that if I save image in a folder parallel to web-inf in my project then it will not be displaying the image.
Can I use any jsp functionality to display image with other outputs from database. I have used "*include*". but it shows only that image and other outputs.

Best way is to use a servlet for this.
<img src="path/to/imageservlet?id=someidentifier">

<img src="path/to/imageservlet/someidentifier">In the servlet's doGet() just write code which gets an InputStream of the image (either directly generated, or just read from the local disk file system, if necessary with help of ServletContext#getRealPath(), or even from the DB by ResultSet#getBinaryStream()) and writes it to the OutputStream of the response. That's basically all. Don't forget to buffer the streams properly to speedup performance and to save memory.
You can find here a basic example: [http://balusc.blogspot.com/2007/04/imageservlet.html].

UIX: how to get dynamic image generation working on ias10G?

Hi,
Anybody got UIX Dynamic Image Generation working on ias10G, on unix? My Images do not get generated (the page only shows the plain links)
My env:
- ias10G
- AIX Version 5
- java version: unknown, do not know what version ias10G is using
On earlier versions (OC4J 903) we had to make sure an XServer was running and pointed our DISPLAY variable to that server. When the XServer was down, we got a nice error message in the application logs. However on ias10G I cannot figure out where to set this variable and I cannot find any error messages.
Can anybody please help me out a bit?
Cheers,
Martijn

Hi Andy,
Thanks for your reply. However, I have not yet been able to get it working.
I have verified that the java version is indeed (this is what the oc4j logfile shows when I supply the -showversion parameter)
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1)
Classic VM (build 1.4.1, J2RE 1.4.1 IBM AIX build ca1411-20030930 (JIT enabled: jitc))The relevant fragment of the opmn.xml:
 <process-type id="oc4j_cif_mh" module-id="OC4J">
 <module-data>
 <category id="start-parameters">
 <data id="java-options" value="-Djava.security.policy=/oracbd/j2ee/oc4j_cif_mh/config/java2.policy -

 <stop timeout="120"/>
 <restart timeout="720" retry="2"/>
 <port id="ajp" range="3301-3400"/>
 <port id="rmi" range="3201-3300"/>
 <port id="jms" range="3701-3800"/>
 <process-set id="default_island" numprocs="1"/>
 </process-type>Finally, your JSP passes the test. I can access it. But still no uix image generation. Are there any logfiles I can check for error messages on the failing image generation? May it be a web cache problem?
Thanks in advance

Dynamic Gifs in JSPs

Hi,
          I am trying to build a server that loads gifs from files, modifies them and
          them uses jsp to output them to client browsers. I am using the GifEncoder
          classes from ACME but from what I can see these were designed to be used
          with Servlets and not JSPs. Has anyone got this to work and if so how have
          you done it. Does anyone have an alternative solution.
          Thanks,
          Ged.


Why do you ever want a JSP to serve a Image?
          If you are generating dynamic images, servlets is the way to go.
          If you still want to use jsp The examples you are looking at will definitely
          work.

Dynamic Image Location in JRC

Hi ! We are interested in using so called dynamic image location future in JRC. So far we are unsucessful, so the question is, is it supported in JRC ? We are able to get dynamic image location future working in report designer, but when our report is exported there is no image only path to it. We use Crystal Reports 11 R2, Java Reporting Component in JSP version. Mac

I have a couple of reports working with dynamic images. CR4E doesn't support this (yet?!?), but you can still do it with the JRC. The big kicker is the syntax of your URL. If you're using a static image on a server somewhere, it should work with no problem. However, if you're using a generated image, it's a little trickier. I discovered this when I was creating a report with barcode labels. The barcodes were not getting generated. I turned on debugging and found that the JRC was screwing up my url. The url was as follows http://myserver/barcode?message=12345 67890&format=datamatrix.
In the logs, the JRC said it couldn't find an image at the url
http://myserver/barcodemessage=12345+67890&format=datamatrix. It was stripping out the ? in the url, which is kind of an important character to say the least. I messed around with it and eventually found that if I just put ?? instead of ?, the image would display correctly with the JRC. Hope this helps! If not, post what version of the JRC you're using and the URL you're using for the image location.

Dynamic image is not being displayed in Adobe Reader 8.1

Hi,
In interactive form, we have followed below required steps to show a dynamic image.
For the left image, drag and drop an Image Field element from the standard Library tab to the Body Pages pane. Select this image field and edit the following properties:
Click on the Layout tab and choose None for the Caption position.
Click on the Object, then the Binding tab and choose None for Default Binding.
Click on the Field tab, enter $record.SapOnlineShopUrl for the URL entry, and select Use Image Size for the Sizing field.
Click on the script editor and enter the following FormCalc script statement, which enables the dynamic integration of the image. Show: initialize Script: this.value.image.href = xfa.resolveNode(this.value.image.href).value;
Language: FormCalc Run At: Client
Image is displayed properly in Adobe reader 7.1 but it's not being displayed in Adobe reader 8.1.
I was going through some forums and understand that Adobe 8.1 blocks href URL. If this is indeed true, what's the alternative way to show a dynamic image?

Chandra

Dynamic image in the template builder plug-in does not work

Hi all,
The documentation says:
Direct Insertion
Insert the jpg, gif, or png image directly in your template.
+...This works obviously+
URL Reference
1. Insert a dummy image in your template.
2. In Microsoft Word's Format Picture dialog box select the Web tab. Enter the following syntax in the Alternative text region to reference the image URL:
url:{'http://image location'}
For example, enter: url:{'http://www.oracle.com/images/ora_log.gif'}
+...This works too when I hardcode an url as url:{'http://www.google.com.tr/images/firefox/mobiledownload.png'}+
Element Reference from XML File
1. Insert a dummy image in your template.
2. In Microsoft Word's Format Picture dialog box select the Web tab. Enter the following syntax in the Alternative text region to reference the image URL:
url:{IMAGE_LOCATION}
where IMAGE_LOCATION is an element from your XML file that holds the full URL to the image.
+...This, however, does not work.+
I use Apex' report query tool and My query is like
select 'http://www.google.com.tr/images/firefox/mobiledownload.png' IMAGE_LOCATION from ... (a single result set for my template)
the xml data is generated with an IMAGE_LOCATION tag. I load it to word template plug-in. The Url successfully displays in the report if I make it a plain-simple field.
But when it's in the image format->web->alt text as url:{IMAGE_LOCATION} no image displayed.
I need to keep this design procedure simple so a simple word user could design a report via using just template builder plug-in. I don't wish to explore the xsl-fo area...yet.
Could you tell me why I can't get this url:{IMAGE_LOCATION} to work?
Regards

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

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

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
 BLOB blob=null;
 rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
 while (rset.next())
 blob=((OracleResultSet)rset).getBLOB(2);
 response.reset();
 response.setContentType("image/jpeg");
 response.addHeader("Content-Disposition","filename=42.jpeg");
 ServletOutputStream ostr=response.getOutputStream();
 InputStream istr=blob.getBinaryStream(1L);
 int size=blob.getBufferSize();
 int len=-1;
 byte[] buff = new byte[size];
 while ((len=istr.read( buff ))!=-1 ) {
 ostr.write(buff,0,len);
 response.flushBuffer();
 ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

How do get a dynamic image to open in new browser window

I'm using DW CS3, mysql (MAMP) OS 10.6.2 I'm designing my online store. I need the customer to be able to click dynamic image/thumbnails to view a larger image in a new browser pop up window 400 x 400. An example of this functionality can be seen at :
http://www.designpublic.com/spot-on-square-roh-dresser
So far I can get the separate new browser window to open with the dynamic image, using the open new browser behavior, but the on click also advances to next page with the larger image. You have to press the back button to get back to the product page. I want the customer to be able to see the product page , while viewing larger image, and then close larger image, and still have the product page open. I don't understand why 2 windows are opening.
Thanks for the help people!
William

Hi
I did look at it but, (and this is only my opinion, I do not like such effects) it is your decision.
If you view source you will see -
<a href="#" onclick="popWin('http://www.designpublic.com/catalog/product/gallery/id/12706/image/91883/', 'gallery', 'width=300,height=300,left=50,top=50,location=no,status=yes,scrollbars=yes,resizable=yes'); return false;" title="Spot on Square Roh Dresser" class="gallery-image-link"><img src="http://arcsmedia01.s3.amazonaws.com/catalog/product/cache/2/thumbnail/56x56/5e06319eda06f020e43594a9c230972d/r/o/roh_dresser1.jpg" alt="" /></a>
Which is controlled by the javascript function
popWin()

Dynamic Image Displays Blank When Using In Visual Studio Project

I am trying to simply display a dynamic image in a report. I am using Crystal Reports XI Release 2.
I have two different environments: Local via Progress where reports are called using Crystal Viewer ActiveX, and over the web where reports are called from Open Laszlo and Visual Studio project.
The image is set to a blank image as default, and Graphic Location Forumla loads the image from the database (site.logo_location + site.logo_filename) which results in an image http:
www.vetinfo3.com\a.jpg.
When I run the reports locally using the ActiveX control, it works just fine and displays the image.
When I run over the web using OpenLaszlo, it displays a blank.
Troubleshooting
We are using Visual Studio 2005, which is bundled with an older version of Crystal that doesn't support dynamic images.
To address this, I loaded Crystal XI Release 2, which updated the version in Visual Studio and enabled the Graphic Location formula field on the dev machine.
I verified the Graphic Location field was set correctly.
This caused a Version error, so we loaded cr_net_2005_mm_mlb_x86.zip on server and specified the Version in web.Config.
No errors now, but when I build and publish the code, the image still displays as blank.

 Blank Image
According to issues within Visual Studio, they say the fix to this is to add the <httpHandler> in web.Config, but it is already there; added when we add the viewer to the project:
In web.Config I have some questions about this line:
 <httpHandlers>
 <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=11.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
 </httpHandlers>
There are more service packs for Crystal XI Release 2:
crXIr2sp2_net_server_install.zip
crXIr2sp3_net_server_install.zip
crXIr2sp4_net_server_install.zip
I have not loaded these yet, but the readme files do not indicate they fix any dynamic image issues.
I am out of ideas on this; does anyone have any ideas?

What about if you take OpenLaszlo out of the picture? E.g.; use one of our samples from here;
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
I'd recommend vbnet_web_simplepreviewreport
Also, see [this|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0437ea8-97d2-2b10-2795-c202a76a5e80] article.

Dynamic Images in PDF Report

Hi,
I want to create Badges from employee table (ID, NAME, JOB_TITLE, PHOTO). I downloaded and installed a demo application "USING DYNAMIC IMAGES IN PDF REPORT". It works fine with smale images < 20K. I'm getting the following error for images > 20K :
"ORA-06502: PL/SQL: numeric or value error: raw variable length too long"
it seems like a buffer problem.
could you pls help to solve this problem
Thanks,
Ribhi

Hi Carsten
That was exactly* I was looking for. Maybe I should Google more in German ;-)
The main problem was that I defined my image outside the first repeating group (that doesn't repeat, it's always just one object) - the first group is followed by 7 more.
Just like the "Name" (that's positioned outside the group in the document header), I positioned the image above the table representing the group.
Doing that, the "Name" is filled correctly, the Image only when the Output Format is Excel or HTML - not Word or PDF ... makes no sense but that's tje way it is.
After moving the image inside the group....it works great!
(One more thing...the image size is fixed to the image you use as "dummy". Is there any way to make that more flexible, because now some scaling happens...)???
@Trent: That was the way we initially did it, but when the size of the row exceeds 32K...you know what happens.. And even with a small image the 32K limit is hit easily
The way I use it now (very similar to Carsten's description) there is no limit....
Thank you all!
Roel
