Focussing on image in struts
can anyone clarify,
if we can focus on an image in struts.
bsampieri ,
You can focus on links, and if the link contents happens to be an image, that's fine
YES ,
there is no problem with handling struts <html:img tag.
I have problem in using Struts <html:image tag.
my JSP code is as below.
I need to fosus " <html:image property="continue" object when page loads
I.e i need to focus on an image when the page loads.
%@ page language="java"%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html:html>
<head>
<title>Test html:multibox Tag</title>
<script>
function fnSubmit(str){
alert(str);
return;
</script>
</head>
<body bgcolor="white" >
<html:form action="html-link.do" focus="continue">
<table border="0" width="100%">
<tr>
<th align="center" colspan="4">html image</th>
</tr>
<tr><td>
<html:image property="continue" page="/images/submit1.gif"

Hi
i am new in struts and i have a image in my data base but i am unable to show that image in struts
what i did tilll now is
i get that images content as binary data and make the InputStream object
but when i try to write that InputStreams data it will not work and didnt show any image
i set the content type image/gif but still facing problem
can any one tell me the solution
thanks alotlQuery = "Select ItemName,CategoryId,Item_image,item_Desc2 from item_master where ItemId='00c63f38-95d9-1028-b9d1-cb9eb7b97c40' and CategoryId='1823bc79-726e-1028-b4b9-b993b5d1f868'";
lStatement = lDAOFactory.getStatement(lConnection);
lResultSet = (ResultSet) lDAOFactory.executeQuery(lQuery, null, null, DAOFactory.SQLTYPEQUERY,lConnection, lStatement);
while(lResultSet.next())
Blob blob = lResultSet.getBlob("item_image");
InputStream istream = blob.getBinaryStream();
result.setM_inStreamItem_Image(istream);
this retrieve the image from the data base
InputStream istream =l_CatalougeItem.getM_inStreamItem_Image();
if(istream!=null)
OutputStream out= response.getOutputStream();
byte dataBytes[] = new byte[istream.available()];
int byteRead = 0;
int totalBytesRead = 0;
while (totalBytesRead < istream.available())
byteRead = istream.read(dataBytes, totalBytesRead, istream.available());
totalBytesRead += byteRead;
out.write( dataBytes );
it write the image in the socket -

How to display dynamic images using Struts
I am storing the image name in bean. I want to use the <html:img> tag to display my images. How can i do that using struts.
Something or sort..
<html:img src=bean:write name="pageEntry" property="pageImg"/>
Thank You* In your web.xml file, add the struts-html-el.tld definition from the struts\contrib\struts-el\lib directory
* Add this tag library to your JSP page; something like:
<%@ taglib uri="WEB-INF/struts-html-el.tld" prefix="html-el" %>* Refer to the following example:
<html-el:img src="${pageEntry.pagePic}" />* This assumes that pageEntry is a Bean, and pagePic is a bean variable accessed by the getPagePic() method. -

Ability to create a collection from a text file containing the names of the pictures
1 thing that would be very good is the ability to create a collection / quick collection from a text file that contains the names of the picture we want in that collection...
The reason for that is when i receive an order from a customer typicaly 100-200 different pictures (i'm a wedding photographer), i ask my customer to send me an excel spread sheet with all the name or number of the picture thay want with size & quantity...
I would like to be able to use that file as an input for a batch job that would add all those files to a collection "customer order" instaid od adding them 1 by 1... it would save me lots of time and would prevent some errors in the order...
I am currently able to do that with the help of a small utility (Useful File Utility) is the name... with the other RAW converter i use... BibbleWell, it is workflow software, true, but it's really focussed on image development. What you're proposing would necessarily make the primary focus be on the business angle, I suspect.
If you're talking about tools to help customers sit down and pick what they want for manual processing later, that's one thing - but going the rest of the distance to order processing and fulfillment would be out of scope, at least in my view. The reason is that there is just so much room for potential variation in how this gets conducted that I can't see how Adobe could possibly satisfy every pro with one implementation. Even just dealing with all of the possible payment vendors is a hugely problematic area.
I agree with Don; a third-party plugin via the upcoming SDK might be a distinct possibility, particularly if it were for a "plus services" solution in which the plugin were designed to work with a specific fulfillment vendor. THAT could work quite nicely, and the plugin might even be free (in return for giving the vendor your business, of course).
In other words, it's not that I see it as a bad idea, it's just that I don't think it belongs in the "core" of LR. This is something that is best dealt with using the SDK so that differences in processes can be allowed for. -
Hi! Just got the 30 day trial of Dreamweaver 8 (and Flash as
well, out of
curiosity) and I would like to find tutorials on the basic
structures of a
web site (folders and so on, the REALLY basic stuff) and then
tutorials or
tricks on how to do a decent but simple web site.
My goal is to create a website mainly focussed on images. So
a lot of
galleries, and probably a lot of updating the site when I
have new pictures
or images to upload.
Thanks for any help!

The tutorials here may be of some help with getting started:
http://www.macromedia.com/devnet/dreamweaver/css.html
As for folders, structure them so that it is easy to maintain
- also
something that makes sense to you. eg: folders for: CSS,
images,
thumbnails, largeimages etc.,

Struts 1.1 Iterate through input types of image
Hi everyone,
I'm using struts 1.1, and specifically the logic:iterate tag. Basically I'm looping through a List of Users. I print out username, userAccessLevel, two image input types (edit or remove). My actionForm associated with the JSP contains the List of Users.
A User object has an AccessButtons field (among other things),
an AccessButtons object contains two Buttons objects named edit and remove,
a Button object has 3 String fields, x, y, and name, and a "pressed()" function
Essentially I want the Action class to be able to pick up what button was pressed on the ActionForm. Specifically both the user and edit/remove action associated with the button. The code I have so far in the JSP is:
<logic:iterate id="users" name="accessForm" property="users" indexId="index">
<bean:define id="ssn" name="users" property="ssn"/>
<bean:define id="accessButtons" name="users" property="accessButtons"/>
<bean:write name="users" property="fullname"/>
<bean:write name="users" property="accessLevel"/>
<html:image property="accessButtons.edit" src="images/edit.gif" border="0" alt="edit" indexed="true"/>
<html:image property="accessButtons.remove" src="images/remove.gif" border="0" alt="remove" indexed="true"/>
</logic:iterate>
This displays the desired output, but it doesn't help be differentiate the user for which the button was pressed. I left out some of the HTML formatting stuff to keep the code clean.
Anyone have any ideas? I hope I explained what I wanted clearly and concisely...yes, this is a problem, isn't it...
I would suggess make each user iterration include a separate form tag set and have a hidden field with the user id. but I think this will still have a problem of knowing which of the 2 buttons were pressed. There is a problem here, cuz Netscape 7 sends the button name of the button and button.x and button.y, whereas IE 6 only sends the button.x and button.y, and not the button as is... which presents a problem to figuring out what was clicked. (Plain submit type buttons seem to be fine for submitting). At least, I guess just check for the existance of the button_name.x to see which was pressed, but you still need the user ID in the forms. -
Combine text and image as submit in Struts
Hi,
I would like to make a submit with a little button AND text, like
"here is image" Research
I'm forced to use Struts, so that the html tag <a href> is not usable.
Can anybody help me?You can allways use the
<html:link action="myAction"/>
</html:link> Or if you don't have the requirement that your pages have to work even with JavaScript disabled you can allways do the following:
<a href="#" onclick="javascript:forms['myForm'].submit(); return false;">

Internal links in portal (CSS, images, and other struts actions)
Good morning gurus! I have another question regarding Struts Portlets. We have an application that builds a page with an image that comes from the database. The application is composed of two Struts actions. One that's in charge of drawing the page and the other action is in charge of bringing the image from the database. The second action is called from a JSP (img src="/getImage.do"). In portal, once the portlet rendered the JSP it doesn't recongnize the other links inside the JSP (the call to the second action). Also, other links suchs as images, CSS, and others Struts actions are not recognized. How can I access images, links, and CSS from the main application (the actual application).
Best regards,
Marcelo Oliva

molivas08Hi Andrew -
This is a pretty big topic for one thread ... I will try to provide some pointers on where to look for more information.
1. Need ability for non-html literate authors to update text, images and links on their portion of a shared web page
In the following whitepaper, see the section: Associated Funtion for Item Display
http://www.oracle.com/technology/products/ias/portal/pdf/oow_10gr2_1336_fender.pdf
This will allow you to prompt your non-HTML literate users for the "parts" to display and you worry about the UI.
2. Need ability to enforce common look and feel on content provided by non-html literate authors.
Create pages based on Templates. Templates can force the style on users. Again - do not use text items and the RTE for users, you control the display with an Associated Function.
3. Prefer ability to approve content before it goes live.
Grant content contributors "Manage with Approval" access
5. Need advanced search capabilities
Check out the search section on Portal OTN
http://www.oracle.com/technology/products/ias/portal/content_management_10gr2.html
Hope this helps,

Managing blob images using ADF and JSF or struts
Hello everyone. I am an ADF newbe and I am developing a web app. that has to manage (display, insert,update and delete) blob images from/to an oracle DB. I've seen the "howto" on image managing using intermedia and struts, but, for this new app I wanted to use JSF (something that is not mandatory) and, what is important is that the DB has already stored the images in blob format.
Can anybody point me in the right direction please??? Is there any howtos on this subject???
Thanks in advance.jfin wrote:
but so far I have to say that I like the fact that I'll have to do very little
System.out.println(<..../>....<>....</>).Assuming that you rather mean out.println() where out is the ServletOutputStream reference returned by HttpServletResponse#getOutputStream(), I can only agree with you. That's certainly not the way how JSP/Servlet code is to be written. The maintainability, extendability, reusability and testability would be far below the freezing point then. You need to write presentation logic in JSP files, not in Servlets and absolutely not in scriptlets inside a JSP.
When you need to write presentation logic which may change per request, use JSTL and EL for that. Again, not scriptlets. For business and controlling logic, use Servlets. For transfer of data, use javabeans (DTO's, VO's). For data access logic, use DAO classes which are to be interacted by servlets.
JSF removes the need for creating Servlets and using JSTL/EL in JSP files. You just have JSP pages with JSF tags for presentation and javabeans for the request values and backing beans for business logic.
When would one use JSF over the other two? When Struts2? When Shale?And you ask that in a JSF forum? At least my opinion is predictable :) -
Help Needed! To upload image to db2 using struts & hibernation[code inside]
Hi all, currently i have successfully created the application for inserting text data into my db2 through the use of struts with hibernation. But i need to insert image now which seems to be different from just inserting text data.
From my understanding, the image will be converted to bytes and store as Blob in my db2, but i need hlp in knowing how to do this, i did a search and i found the following codes posted by another guy in this forum but he did not reply his thread at all...i am feeling very puzzel about the last file which is /RegPersonalDetails.java. Did he missed out a bean file?? which is the TempPhoto bean? i really do not understand the last file, The first file is the JSP , the second is the bean and the third is the Action class. i did exactly the same as his but i do not know how to use the RegPersonalDetails.java. please help thanks.. i am using websphere studio 5 and hibernate 2.
Below is the example i got from the guy:
//Registration.jsp
--Below is the script for image type validation.

var source=what.value;
var ext=source.substring(source.lastIndexOf(".")+1,source.length).toLowerCase();
for (var i=0; i<fileTypes.length; i++) if (fileTypes==ext) break;
var globalPic=new Image();
if (!(i><fileTypes.length)){
alert("THAT IS NOT A VALID IMAGE\nPlease load an image with an extention of one of the following:\n\n"+fileTypes.join(", "));
what.fileUpload.focus();
return false;
else
return true;

Add Image to Jasper Report with Struts 2 and Hibernate
Hi I want to add image to jasper report[pdf] in the environment of Struts 2 framework and hibernate. I am trying
this for last couple of days, but i am unable to get the work done. if any body know the steps to add image to
jasper reports, please help me or if u have any tutorials please let me know. I am using iReport-nb-3.5.0 to generate jasper files.
Thanks in advanceFinally i found a way to add image to jasper report. It is pretty simple, just give the exact image location to the image expression. In your web application, the image location may vary so, dynamically set the image location from your model class. Also, make sure that your lib folder contains itext-1.3.1.jar. If your lib folder contains itext-1.3.1.jar and iText-2.1.3.jar u will get like: java.lang.NoSuchMethodError: com.lowagie.text.Image.plainWidth()F
So remove the iText-2.1.3.jar and keep only itext-1.3.1.jar, try this will work -
Struts Portlet does not show images when it is accessed outside the domain
Hi all,
I am using Oracle 10.1.2. I have created a Struts portlet. When I view the struts portlet from my office domain (University domain) it works well and shows the images properly. However, if I try to access the same page containing the struts portlet from some other domain (my home), I cannot see the images and CSS associated with the page. This might be a firewall issue. Is there any way out?
Best regards,
OmerI fixed the problem. (YAY!)
It was the way I embedded the files -- the Dreamweaver default does not work properly so I used the embed from this generator: http://www.bobbyvandersluis.com/swfobject/generator/index.html#alternativeContentHelp which now lets my navbar and swfobjects load properly. I also made sure that my slideshow (loader.swf) was set with wmode = opaque while the navbar is set to wmode = transparent. The div for the nav bar has z-index set to 5 while the div for the slideshow has z-index set to 1. Both have absolute positioning. I hope this helps anyone in the future that has trouble with overlaying flash (.swf) files.
Thanks for your reply and trying to help me solve this issue!
