How to display an image located in the WEB-INF directory?

Basically, When a user registers, they a directory is created with their username that holds images that they can upload. How do I display those images. All I am holding in the database is the location of the images.
ive tried
<img src="/WEB-INF/users/testuser/picture.jpg" />
but this doesnt work and for obvious security reasons shouldnt.. but is there another way of doing what i want to do? perhaps a custom tag? thanks
Jazz

You would have to write a generic servlet that would return an image
<img src="/getImage?user=testuser&pic=picture.jpg" />Your servlet would basically fetch the file from under web-inf, and then stream it back to the user.
Methods to use:
servletContext.getRealPath() (to help find the file on disk), relative to your web app
getOutputStream (as opposed to getWriter)
It is only in this way that you can access files on the server outside of the public web directories.
Hope this helps

How can I reference a dtd in the Web-Inf directory from an xml file?

Hi,
I've placed my test.xml and test.dtd files in the following
direcory (part of my web application)
weblogic\config\MyDomain\applications\sample\Web-inf
When I refer to the dtd from the xml file, as follows,
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE application SYSTEM "test.dtd">
Weblogic tries to look for the dtd in the weblogic directory(the
place where I started the server from). How can I get it to read
the dtd in the Web-inf directory?
I'm using Weblogic6.0 SP1 on Windows NT 4.0
Thanks.

Two options:
1) Use SYSTEM "http://localhost:7001/sample/test.dtd"
2) Or use XML registry in WLS6.0

How to load/save a file in the WEB-INF?

how can i load and save files in the WEB-INF directory using servlet?

This doesn't save files. And in order to reuseability and maintainability, I'd rather use java.io and passing the path/filename around in File object.
You can retrieve the absolute path for "/WEB-INF" byString absoluteWebInfPath = getServletContext().getRealPath("/WEB-INF");Then you can use that to read/write files.
File file = new File(absoluteWebInfPath, "filename.ext");
InputStream input = FileUtil.read(file);
FileUtil.write(file, input);and so on.

Serializing a JavaBean to the WEB-INF directory or subdirectories

Hello, I'm hoping someone can help me on this.
I'm working with two scenarios in WSAD Enterprise Edition 5.0.0.2 for
serializing a JavaBean (called AddressBean) to the following location
in my Web application:
/WEB-INF/classes/resources/serializable
The data corresponding to the bean I'm serializing is being stored in
a file with a name that makes it unique on the file system (e.g.
jeff.ser, jill.ser). In the first scenario, I start by getting a
FileOutputStream, then an ObjectOutputStream which is then used to
write my JavaBean as needed. All of this is done in the first
scenario from a JSP located in:
myWebApp/Web Content/jsp/JSP1.jsp
That works fine and as I'd expect. However, I'm not able to do that
in the second scenario. In this scenario, I created an additional
method in the bean itself that will actually serialize an object of
its own type to the same directory structure that I showed above (i.e.
under the WEB-INF directory). That is, in my bean, I have the
following:
public void writeDataToFile(AddressBean bean, String path) {
FileOutputStream fos = null;
ObjectOutputStream oos = null;
try {
fos = new FileOutputStream(path);
oos = new ObjectOutputStream(fos);
oos.writeObject(bean);
oos.close();
catch(Exception e) {
e.printStackTrace();
In this scenario, another JSP (call it JSP2.jsp) is creating an
instance of AddressBean by using the jsp:useBean tag. The real path
for the .ser file is figured out in the JSP code (same as was done in
JSP1.jsp), and then I delegate the serialization part to the bean
itself like so:
// In JSP2.jsp
<jsp:useBean id="ab" class="examples.beans.simple.AddressBean" />
AddressBean address = (AddressBean) pageContext.getAttribute("ab");
// get the path
String path = ...
String realPath = application.getRealPath(path);
// write the object
address.writeDataToFile(ab, realPath);
What happens is that I get a FileNotFoundException while trying to
create the FileOutputStream in the writeDataToFile() method in
AddressBean at runtime. The message in the console states:
java.io.FileNotFoundException:
C:\WINNT\Profiles\myself\Personal\IBM\wsad\myworkbench\myWebApp\Web
Content\ (Access is denied)
The source file for AddressBean is located at:
myWebApp/Java Source/examples.beans.simple.AddressBean
WHAT is going on here!? I know that everything stored underneath the
WEB-INF directory is not served to clients so I'm also assuming that
whatever stored in that directory or its subdirectories is not
accessible to clients by default. The only real difference between
the two scenarios that I've described is that in the second one, the
attempt to get a FileOutputStream is being made by a resource (i.e.
AddressBean) that is outside of the "Web Content" directory structure
in WSAD. However, the "Java Source" directory, which contains the
package housing my AddressBean class, is also under myWebApp so I'm
not seeing what the problem is at the moment.
If anyone has any ideas, suggestions, solutions, please let me know.
I'm stumped. Thank you!
Jeff

I figured it out, and it was my mistake. The problem was in a method defined in my AddressBean class that would take a String argument and use it to help create a unique file name (i.e. one with a .ser extension to contain the serialized bean data) for purposes of serialization later.
Basically, I was using a local variable in the method unintentionally instead of the instance variable that I had defined in the bean so my path value was null at runtime--hence the FileNotFoundException.
I'm still not sure why the (Access is denied) message was appearing, but I suspect it was b/c the absolute path that I'd end up with at runtime wasn't kosher; or, not having a destination .ser file was the problem.
In any event, I fixed the mistake and could serialize a JavaBean in several ways:
1. From a JSP directly
2. By using a method defined in the JavaBean itself
3. By passing on the request, which contained the JavaBean as an attribute, to a servlet that took care of the serialization

Storing .jsp files in the web-inf directory

Has anyone ever heard about storing JSP files in the web-inf directory instead of the web app root directory.
Apparently it improves security.
If this is so, how is the user suppose to access the jsp file since I thought that users were not able to access what is stored in the web-inf directory.
Any thoughts
Thanks
Nat

I didn't tyr this but I think it is possible. You can do it using <servlet-mapping/> as you do with any other servlet.
For example include lines below, in web.xml of web-inf,
<servlet>
<servlet-name>ReportRouter</servlet-name>
<jsp-file>/web-inf/jsp/ReportRouter.jsp</jsp-file>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ReportRouter</servlet-name>
<url-pattern>/myrouter</url-pattern>
</servlet-mapping>
This may work. Don't you think so?

How to display an SAP document on the web (ECC 6.0)

Hello all,
currently upgrading from 46C to ECC60 and we are having trouble with one of our current processes.
We currently have a custom RFC that creates spool files and turns them into a PDF stream via CONVERT_OTFSPOOLJOB_2_PDF. The RFC is called from one of our web applications that then displays the document via PDF on the web.
We are having trouble using this same process in ECC 6.0 so I'm wondering if there is a different approach to do this in ECC 6.0.
History of what has been done so far.
1) since we are now on a UNICODE system the PDF stream sent via the RFC call was displaying chinese characters instead of "%PDF" etc (2hex char vs 4hex char). We attempted to fix this by using the method cl_abap_conv_in_ce=>create to convert each line of the PDF stream.
2) After inserting the method some of the documents started working but others are getting a parsing error.
We are looking to see if anyone knows of a more standard approach to getting the same thing done.

We have experienced the same problem since we upgraded to ECC 6 and unicode last week. The suggested code worked but there was a step missing in the example that I would like to share.
The spool output was table TLINE which is 134 characters. Once you convert to non-unicode you actually have to put the results in a 268 char table. When you read it in .NET and convert it to a binary array before passing it to Acrobat for viewing you have to make sure that you pad each record with spaces up to 268 charactes. This was key!
Here is the code from our RFC after calling the CONVERT_OTFSPOOLJOB_2_PDF with a spool id:
data: PDF STRUCTURE ZC268_STRUCT occurs 0 with header line.
call function 'CONVERT_OTFSPOOLJOB_2_PDF'
exporting
    src_spoolid                    = f_rqident
tables
    pdf                            = pdf.
data:     rf_conv type ref to cl_abap_conv_in_ce.
rf_conv = cl_abap_conv_in_ce=>create( encoding = 'NON-UNICODE' ).
data: fta_data type table of zc268_struct with header line.
data: f_str    type string.
field-symbols: <f_src> type x.
loop at pdf assigning <f_src> casting.
     call method rf_conv->convert(
      exporting input = <f_src>
      importing data = f_str ).
      fta_data        = f_str.
      append            fta_data.
      clear             fta_data.
endloop.
The data in fta_data can be passed to .NET
I hope that helps.

How can I forward to a jsp under the WEB-INF directory?

I have a webapp with a jsp that forwards to a jsp called /WEB-INF/pages/secure.jsp When I try to forward to it, I get the error:
"trying to GET /mywebapp/WEB-INF/pages/secure.jsp, deny-existence reports: denying existence of /web/webapps/mywebapp/WEB-INF/pages/secure.jsp"
How can I forward to this page?
Thanks,
Micah

Craig - I'm trying to do something very similar - build a waiting page into the
flow. I've got a support case open (to get the BEA recommended approach) but so
far have had no luck. Let me know if you've found the answer - or are still struggling.
Cheers,

I am trying to get a JSP in a portlet to forward to a Webflow URL,

The following code produces the ubiquitous "Functionality temporarily

absolute URL:
<c:set var="url">
<portlet:createWebflowURL event="next"/>
</c:set>
<%
// convert to a scripting variable for the jsp:forward tag
String url = (String) pageContext.getAttribute("url");

<jsp:forward page="<%=url%>"/>
Using c:redirect fares little better. This code produces an empty
portlet:
<c:set var="url">
<portlet:createWebflowURL event="next"/>
</c:set>
<c:redirect url="${url}"/>
The closest I've been able to get is to have the user click a link to
get to the next page, but I'd like to have an automatic forward rather
than introduce another mouse click:
">
Click to continue...</A>
Am I missing something obvious? Any help would be appreciated...

Support for JSP's located in WEB-INF directory

Several application servers support the use of placing JSP pages underneath the WEB-INF directory, to insure that only server side workflow forwards requests to those pages and not direct URL access. IN addition the JSTL specification supports the use of
<c:import url="/WEBINF/published/campaign_Arts.jsp" />
Does OC4J 9.0.3 support this syntax? I cannot get it to work. Is there an application configuration file I need to update to support this?
Thanks

          thank you for your reply...
          but...
          My problem is that i want to serve jsp pages that include various other jsp pages.
          But i don't want those other pages to be served directly. The approach of putting
          the jsp files in the WEB-INF, or in a sub directory of it, worked fine on Tomcat.
          The way i look at it is that the server has direct access to them when putting
          togetter the main jsp, but they can't be accessed from the outside. But this seems
          not to be the case.
          Any ideas?

How to display URL images and URL link (html) from Smartforms?

Hi Gurus,
I'm having difficulty on how to display targeted URL images and URL link from the smartforms, after i sending it out as html mail. The mail i sent just can be preview as a plain text, which can't execute the html code that i put inside the smartforms itself. I follow a few step from this very useful blog.. Hopefully, you guys can give me some solutions or ideas on this.

1- put your images in a directory under the web app directory. Example: app/images/
2- in your jsp, use: String file = application.getRealPath("/images/"); to get the images directory. See http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
3- it's not the right forum to post this kind of question. Post them in the JSP/Servlet JSTL forum instead

Hi,
byte[] img = wdContext.nodeYywwwdata_Import_Input().nodeOutput().nodeOutMime().currentOutMimeElement().getLine();
use this code to create resource and you need to set this value to the context created to display the image suppose in the image UI and set the source property with this attribute:-
IWDResource res=WDResourceFactory.createCachedResource(b,"MyImage",WDWebResourceType.JPG_IMAGE);
IPrivateAppView.IVn_ImageTabElement imageEle=wdContext.createVn_ImageTabElement();
imageEle .setVa_Name(res.toString());
wdContext.nodeVn_ImageTab().addElement(imageEle);
Hope this may help you.

How to Display an Image on my FORM

Good Day!
I would like to ask some help from you guys with my problem on how to display an image on my form. I would like to display my uploaded image on my form but instead of an image, the get_blob_file is showing. By the way, I'm using Apex 4.1
I downloaded the Order Entry Sample Application and followed the Page 6, the Product Details. I even made snapshots of each details from Page Rendering to Page Processing in order not to miss a thing.
At the moment, I was able to upload or store the image on my created Oracle table and also able to retrieve it on the Download Link Text with Content Disposition value of Inline, provided by APEX Settings. If I invoke the Download link beside the file browser, a page with the image will be shown, below is the address:
http://127.0.0.1:8080/apex/apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6&p_content_disposition=inline
However, instead of showing the image on a region, below is the one showing on my Form:
<img src="apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6" />
As you can see the parameter values are the same but I know I missed something that's why I'm here :)
I would highly appreciate all the help you can provide and many thanks in advance.
I tried to change gear by making an html region of type PL/SQL (anonymous block) and a procedure but still no image :(
Below are the scripts.
declare
cursor cur is
select *
from wsemployee
where empid = :P230_EMPID;
begin
for rec in cur
loop
IF rec.mime_type is not null or rec.mime_type != '' THEN
htp.p( '<img src="my_image_display?p_image_id='||NVL(rec.empid,0)||'" height="'||100||'"/>' );
else
htp.p( 'No Image ');
END IF;
htp.p( ' ');
end loop;
end;
PROCEDURE
create or replace PROCEDURE my_image_display( p_image_id IN NUMBER)
AS
l_mime VARCHAR2 (255);
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc BLOB;
BEGIN
SELECT MIME_TYPE, PHOTO_BLOB_CONTENT, PHOTO_FILENAME,DBMS_LOB.GETLENGTH(photo_blob_content)
INTO l_mime,lob_loc,l_file_name,l_length
FROM wsemployee
WHERE empid = p_image_id;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(l_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || l_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(l_file_name,instr(l_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
END my_image_display;

How to display an image, which is stored in a database?

Hi All,
I would like to display an image with Web Dynpro.
I already know how to display an image which is stored in the path src/mimes/Components/...
But does anybody knows, how to display an image which is stored in a database (e.g. MaxDB)as a datatype of binary?
Thanks in advance!
Regards,
Silvia

Hallo John,
yes, you can use the Image UI element.
Further you have to create a String for the URL. Implement like as follows:
IWDCachedWebResource cachedResource = null;
String imgUrl = null;
WDAttributeInfo attInfo = wdContext.getNodeInfo().getAttribute(IPrivateXYView.IXYElement.PIC_DB);
IWDModifiableBinaryType binaryType =
(IWDModifiableBinaryType) attInfo.getModifiableSimpleType();
binaryType.setMimeType(WDWebResourceType.JPG_IMAGE);//Example *.jpg
WDWebResourceType type = binaryType.getMimeType();
byte[] file = wdContext.currentXYElement().getPicDB();
if (file != null)
cachedResource = WDWebResource.getWebResource(file, type);
try
imgUrl = cachedResource.getURL();
catch (WDURLException e)
IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();
msgMgr.reportException(e.getLocalizedMessage(), true);
I hope it will help you.
Regards,
Silvia

How to display an image using MIDP on Palm?

How can I display an image using MIDP on Palm? The following code works on the Siemens SL45i, but not on Palm:
public class Test extends List
Image image = Image.createImage("/images/test.png");
append("item 1", image);

Have found the exact same problem when trying to display an image (other then the default (null)) in a list, on a Palm.
The image displays correctly on a form, but when set on an element in the list, it does not display. (mind you this is in both emulator mode and on the real device)
It does not seem to be related to size of the image.
The Sun documetation states, that you should not rely on it been displayed (obviously it's an implementation issue with the Palm, and other devices I have not tried)
But like to hear definitively from Sun though!
