Displaying a Blob with a Dynamic Page

A dynamic page was created where one of the columns on the database table is a BLOB. The following error is received when trying to query the column from the dynamic page:
: Unable to execute query (WWV-10201)
The preference path does not exist:
ORACLE.WEBVIEW.PARAMETERS.1093150906 (WWC-51000
FYI - when running a similar query from a form component, the blob displays fine. This problem occurs only with dynamic page components.

Hi,
What version of Portal are you using ??
Have you tried using reports like QBE,Wizard or SQL rfor displaying Intermedia Objects.
Thanks,
Anu

You must to use the htp package. Example:

begin
htp.tableopen('1','CENTER',null,null,'BORDER="1"');
htp.tableheader('NParte','CENTER');
htp.tableheader('Descripcisn','CENTER');
htp.tableheader('Precio/Unit','CENTER');
htp.tableheader('Servicio','CENTER');
htp.tableheader('IVA','CENTER');
htp.tableheader('Total','CENTER');
for cursor_cotiza in (select
r.Nparte as Nparte, r.Descripcion as Descripcion,
r.preciounit as preciounit,
NVL(f.servicio,0) as servicio,
round((0.145)*r.preciounit,3) as IVA,
round((0.145)*r.preciounit,3) + r.preciounit +
NVL(f.servicio,0) as PrecioTotal
from
carryin.repuestos r,
carryin.casos c, carryin.facturacion f
where r.NCaso =:NCaso
and r.Ncaso=c.NCaso
and c.Ncaso=f.Ncaso(+)
and f.servicio(+)<>0
union
select
r.Nparte as Nparte, r.Descripcion as Descripcion,
r.preciounit as preciounit,
NVL(f.servicio,0) as servicio,
round((0.145)*r.preciounit,3) as IVA,
round((0.145)*r.preciounit,3) + r.preciounit +
NVL(f.servicio,0) as PrecioTotal
from
carryin.casosneq r,
carryin.facturacion f
where r.NCaso =:NCaso
and r.Ncaso=f.Ncaso(+)
and f.servicio(+)<>0
) loop
htp.tableRowOpen('CENTER','CENTER');
htp.tableData(cursor_cotiza.Nparte,'CENTER');
htp.tableData(cursor_cotiza.Descripcion,'CENTER');
htp.tableData(cursor_cotiza.preciounit,'CENTER');
htp.tableData(cursor_cotiza.servicio,'CENTER');
htp.tableData(cursor_cotiza.IVA,'CENTER');
htp.tableData(cursor_cotiza.PrecioTotal,'CENTER');
htp.tableRowClose;
end loop;
htp.tableclose;

This example show a table with header and borders. You must to see this package for more information.

My browser displays text only with very little page formating for all pages. How do I enable page formating with images etc.?

I have a multi-user windows based machine where both users have the same browser, search engine, plugins, applications, etc. I use this machine primarily as an entertainment system (ie. TV client/server using a TV Tuner card, Music & Video Player, etc.). Most of my time on this machine is maintaining security and drivers. However, my wife uses it primarily as a social media communication device. My user account on this machine displays all content correctly. Where as she has crashed both Facebook games while playing as well as her mail (GMail). After one of these crashes it "appears" she is displaying HTML text with formatting but without images. I've tried to fix this without success. We have another machine that seems fine so it's not her login on our network, just the one machine. Please help!!!

How to display 3 alv with top-of-page using splitter container

Hi,
I want to display 3 different alv in a single container corresponding to the 3 check boxes on selection screen.
i.e.
If user selects 1 check box only one alv should be displayed, if 2 checkboxes selected by user 2 alv should be displayed and same for 3.
I cannot use 3 different containers bcoz if second checkbox is not selected then that place remains blank. So I am using single container and using splitter container dividing it into the no of rows corresponding to the no. of checkboxs selected by user.
Now I also want to display top-of-page for each alv. Please guide me how to achieve this.
Thanks & regards,

View display image BLOB with PHP!

I using..
$consulta = oci_parse($conexao,"select photo from userp where usrph_status = 'A' and id = :didbv");
$didbv = $_POST["id"];
oci_bind_by_name($consulta, ':didbv', $didbv);
oci_execute($consulta, OCI_NO_AUTO_COMMIT);
while (($row = oci_fetch_array($consulta, OCI_ASSOC)) != false) {
$arr = oci_fetch_assoc($consulta);
header("Content-type: image/JPEG");
$result = $arr['PHOTO']->load();
print "<img src='".$arr['PHOTO']."'>";
print $result;
echo $result;
What appears in the result page is:
This image contains errors and can not be displayed.
How to fix this?

- With that content type, you should be sending only binary data, not the HTML "<img" text.
- You have both a print and and echo.
Look at script 105 on p.236 of The Underground PHP and Oracle Manual | Homepage

Displaying a blob into an image on OAF Page

Hi everyone,
I read this topic Re: Displaying an Image stored in the Database as BLOB on OA Fwk Page
but is there another way to display a blob image on OAF Page?

Hi,
Yes I am using same code specified by Kali. My requirement is exact same with it.
The debugger does not jump to the servlet class from CO.
By the way the CO and servlets are in the same package.
This is the page source;
<img id="imageIT" name="imageIT" src="ReadPerImage?id=4
{code}
This is the servlet mapping in web.xml;
{code}
   <servlet-mapping>
      <servlet-name>ReadPerImage</servlet-name>
      <url-pattern>/readperimage</url-pattern>
   </servlet-mapping>
{code}
Thanks.

Displaying data on a Dynamic page.

Hi,
I know i had asked a similar question before of creating a multiple record form. I was given an
answer that i could create a dynamic page. I am trying to create a dynamic page based on a table
but most of the fields that i will display on the form are non database fields like description
and all. All the fields will be display only.
On the Dynamic page content where we can write the pl/sql code and HTML Code i am under HTML code
creating a table because i need to show the data in the form of grid and inside oracle tag i have
open some cursors and all to get the value for my non database fields.
The problem i am facing is how to pass those values to the HTML table and display on the form.
Please Help.
Thanks,
Amit.

Using Template information in dynamic pages

Having created some interface templates for my current project, I find I am not able to readiily use them in dynamic pages.
Is there a technique for this, that allows me to get the details from my page styles / Interface templates and combine them with output dynamic pages?
I am able to associate backgrounds ( for example ) with customization forms, but not output.

I understand the desire to not use an applet. Have you tried an html pop-up? This will create a separate http request through to your server on the user's same session. This allows your server to do the required processing to display the data to the user via html.
Use the target="_blank" attribute of the anchor tag, or a window.open JavaScript method.

Over-ride default customization for Dynamic page portlet

has anyone been successful at over-riding the default customization that comes with the Dynamic page wizard. I have a portlet that will have specific values for each user and I would like to default those values the first time the user comes in. The delivered customization screens are not adequate to do this.
Any ideas would be appreciated...
null

The question is not related to dynamic services. It is related to over-riding the default customization delivered by the Oracle portal dynamic page wizard. I need to figure out using the PDK how to enhance / over-ride the default customization that is generated. Is the preferred approach to go through the wizard and then modify the code that gets generated or should you just start from scratch and never use the wizard at all?
Thanks,

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 to add a column to a list created with the Dynamic List Wizard to display the values of the fiel

Hi,
ADDT, Vista, WAMP5.0
We have 2 tables: clients_cli (id_cli, name_cli, tel_cli, and several more fields) and cases_cas (id_cas, idcli_cas, court_cas, and a lot of other fields).
Clients may have many cases, so table cases_cas have a foreign key named idcli_cas, just to determine which case belongs to which client.
We designed the lists of the two tables with the Dynamic List Wizard and the corresponding forms with Dynamic Form Wizard.
These two forms are linked with the Convert Dynamic List and Form Wizards, which added a button to clients list named "add case".
We add a client and then the system returns to the clients list displaying all clients, we look for the new client just added and then press "add case", which opens the Dynamic Form for cases, enter all case details and everything processes ok.
However, when we view the cases list it display all the details of the case, including the column and values for the foreign key idcli_cas. As you can image, it is quite difficult for a human to remember the clients ids.
So, in the cases list we added a another column, named it Name, to display the names of the clients along with cases details. We also created another recordset rsCli, selected the clients_cli table, displaying all columns, set filter id_cli = Form Variable = idcli_cas then press the Test button and everything displays perfect. Press ok.
Then, we position the cursor inside the corresponding cell of the new Name column, go to Bindings, click on name_cli and then click on insert. The dynamic field is inserted into the table cell as expected, Save the page, and test in browser.
The browser call the cases list but fails to display the values of the Name column. The Name column is simply empty.
This issue creates a huge problem that makes our application too difficult to use.
What are we doing wrong?
Please help.
Charles

1.     Start transaction PM01, Create Infotype, by entering the transaction code.
You access the Create Infotype screen.
2.     Choose List Screen.
3.     In the Infotype no. field, enter the four-digit number of the infotype you want to create.
When you specify the infotype number, please remember to enter any leading zeros.
4.     In the Screen Number field, enter the screen number of the list screen you want to enhance.
5.     Choose Create.
The Dictionary: Initial screen appears:
6.     Create the list screen structure.
7.     Choose Activate.
8.     Return to the Enhance List Screen in the Enhance Infotypes transaction (PM01).
9.     Choose Create All.
The additional fields are displayed on the list screen, however, they contain no data.
The fields can be filled in the FORM routine FILL-LISTSTRUCT in the generated program ZPnnnn00. The FORM routine is called for each data record in the list.
Structure ZPLIS is identified when it is generated with a TABLES statement in the program ZPnnnn00.
The fields can be filled from the Pnnnn structure or by reading text tables.

Dynamic page in region as a portlet not displaying in portal template

As the title suggests I have a portal template that contains a region at the top . within this region i have included 2 portlets, first is a dynamic page (a simple banner title ) then a navigation page beneath them .
when I am logged in as a specific user it displays correctly , when I log onto the page without logging in - the dynamic page does not display ,yet the navigation page does . I have clicked on every display to public check box , assigned public user with view privilege and everything else along those lines . Any ideas ??
thanks in advance , Chris

Hi Chris: Just to be specific, did you go to the providers tab in Navigator, the locally built providers link then the provider which contains your dynamic page and check the access set directly on that page? You can either set the dynamic page to have its own access (overriding that of the provider) or set the provider itself to be public.

Problem with a Link calling a dynamic page

Hi!
I wanted to create a link calling to a dynamic page. This dynamic page displays a PDF depending on the parameter, the thing here is that I don't know how to set the bind variables or more likely how to say that the value of those variables is going to come from the link in which the dynamic page it's been called.
I have my PL/SQL code where I have this bind variables
id_dep
id_tipo
and I went to the Customization Form Display Options button and there i made them public.
now on a page i created a link with the following structure, in order to call the dynamic page and send the parameters.
http://your.portal.com/portal/pls/portal/SCHEMA.DYN_YOUR_DYN_PAGE_NAME.show?p_arg_names=YOUR_PARAMETER_NAME&p_arg_values=YOUR_PARAMETER_VALUEso my links looks like this one:
http://desarrollo06:7778/pls/portal/TRANSPARENCIA.NOSEQUE.show?p_arg_names=idDep&p_arg_values=11&p_arg_names=idTipo&p_arg_values=25so I was told that I had to check that the parameters bindings are present or set, but I don't know how to do that... 'cause I thought I already did...
can youi help me?
thanks In Advance
aTTe
Blume

Hi AMN,
well what I meant was that, see in the manage page for the Dyn Page there are some options bellow, in the one that sais Customize you can test the page, and I put there the values for id_dep and id_tipo as *11* and *25* then run the page and it opens the PDF but when I click on the link you suggested
http://desarrollo06:7778/portal/pls/portal/TRANSPARENCIA.NOSEQUE.show?p_arg_names=idDep&p_arg_values=*11*&p_arg_names=idTipo&p_arg_values=*25*
u_u but it doesn't open the PDF.
...The code I put in my last post is the code for my dyn page, and there's an if where if it doesn't find a file to deploy it show a message that sais "No hay Datos o No Aplica", so when I clic on the link it takes me to the dyn page but shows the message for no data found...
so I don't know what's going on.... if supposedly the dyn page is receiving the same values in different way, why it doesn't work with the link? -_-

How to display dynamic page content in an external application (MS Word)?

I have a portal that generates a CV from info stored by various forms. The CV displays fine in a dynamic page, but when I add javascript to launch MS Word with a call to the dynamic page portlet, only the hard coded html displays - nothing between the <ORACLE> tags is loaded.
I had the idea of updating the dynamic page with hard coded html prior to each export - but I can't find where the dynamic page definition is stored in the database.
Any ideas/better solutions out there?

dynamic page:
<ORACLE>
DECLARE
theUser varchar2(30) := portal30.COE_GET_CV_PERSON;
v_output varchar2(6) := portal30.COE_GET_CV_OUTPUT;
v_no number;
v_url varchar2(500):= 'http://oraclecoedb.asiapacific.cgey.com:7779/pls/portal30/PORTAL30.wwv_component_control.run_as_portlet?p_module_id=1934976747';
BEGIN
IF v_output = 'WORD' THEN htp.script('startWord('||''''||v_url||''''||');','Javascript');
ELSE null;
etc ...
javascript:
<script language="JavaScript">
function startWord(strFile)
var myApp = new ActiveXObject("Word.Application");
if (myApp != null)
myApp.Visible = true;
myApp.Documents.Open(strFile);
</script>
