Caching in Dynamic Pages

Hi,
I have created a dynamic page(HTML) and published it as a portlet. I have included a call to display an image(say xyz.jpg) in the code. I have also published this dynamic page as a portlet and use it in a portal page. When I view the page it shows the image. When I change the underlying image(xyz.jpg), the new image(please note that that the images are different but the path and file name are the same) is not showing up in the portal page. Instead, the old image file is displayed. I have given Don't cache for the portal page. I also tried clearing cache for the page group, portal page and the dynamic page and it still displays the old image and not the new one. Is there a way to clear cache dynamically?
Thanks,
Manikandan Vembu

Hi,
This is a known issue with the way Wordpress generates the URLs to included content:http://forums.adobe.com/message/4774943
Wordpress generates absolute URLs to content rather than relative URLs, so the current workaround is to either use relative URLs or, if that's not possible, modify the wordpress configuration to use the IP address instead of localhost.
Hope this helps,
Mark

Disable caching for dynamic pages

          How do you set up a directory that is not cached by weblogic?
          I have a servlet which generates Images (to this directory) and then the images are
          displayed as part of the HTML.
          Work ok on testsystem (which is WL 6.0/ NT) but doesn't work on Solaris / WL 6.1
          - it appears as though on startup, the WL Server caches dir contents and becomes
          unaware of new entries?


I don't believe that is possible.
Instead of 2 Bundles, you could create a System Requirement on the
Distribution Action so that it does not distribute on VDI machines.
Then for the Launch Actions, do something similar so it launches the
local or network copy depending on if it was VDI or not.

Dynamic pages submitting data to stored procedure

Hi,
I am developing an Oracle Portal application and I am facing a problem, if anyone could help me I'd be very grateful.
I have the latest version of Portal 3.0.9, installed on a linux server. I'm using I.E. 6.0 to interface with Portal.
I have a dynamic page that have a <form> tag, like this:
<form name="MyFormName" action="MySchema.MyStoredProcedure" method="post">
I changed the form name and the stored procedure name, because I'm in Brazil and these names are in portuguese, it won't make much sense in english...
Well, problem is, when I click on submit button, instead of calling the stored procedure, the browser tries to load a page called "http://MyServer/pls/MyDAD/MySchema.MyStoredProcedure" instead of calling the actual stored procedure. The procedure have all the parameters defined on <input> tags within the html code of the dynamic page.
I don't know what else I can do, any help or hint would be greatly appreciated. Sorry for my bad english.
Thanks In Advance,
Tiago Rocha

Have you specified any value (greater than 0) in the Portlet expires in ... minutes field ?
If you have, then I guess your dynamic page is getting cached.
Before submitting the form, do a right click on the browser page and view the page source.
What does the <form> tag look like ?
Does it still show the old procedure name ?

Dynamic pages with WebCenter Sites CSElements

We are using the benefits of WebCenter Sites 11g regarding the possibilities of create the templates and the final user be able to compose the the pages. By the other hand, we have the necessity to create dynamic pages with business logic and interaction with database or web-services with WebCenter Sites templates. We expect to be able to embed these dynamic pages inside CSElements. With all of this in mind, what is the best approach? I'd like to know if our solution to use the Spring 2.5 + JPA 2 is a good a approach to reach our necessity/requirement or WebCenter Sites 11g has another better way to do that.

You can add your own business logic to CSElements, or create your own tag libraries and add your logic there. If you're using a framework like the GSF you can call an action from your element as well. In all cases, you are free to use whatever tools you like to help you implement your business logic (provided that it is compatible, which you've already learned about. :-). Just be careful that you don't use the same database connection pool that Sites uses or you may run out of connections. Also, pay attention to how you are caching your pages and pagelets when you are calling external services or accessing external resources.

WebDB - Dynamic Pages SVG/HTML Encoding Help

I have been playing around with WebDB 2.2
to generate an SVG document from a table with X/Y locations
in columns.
I can generate the SVG content fine but when WebDB sends it to
my browser (IE 5.5) it is displayed as XML rather than as an SVG document.
Now I think that the problem is that the document does not have an SVG extension
and WebDB is typing the document as HTML. When I check the properties of the
document (right mouse click and select properties), Windows tells me the type of the
document is HTML. If I File>Save the document with an SVG extension and then open it
in IE I get my map.
I can't see how to force WebDB to change the document type.
Can anyone help me?
I hope I am making sense :-)

Refreshing query data for Dynamic Page Generator

Can anyone tell me why I must exit out of XMII and re-login in order to have any updates saved in either a Data Query or Display Query show up when I use the Dynamic Page Generator.
I attended the Xmii beginner level training. In the training, I could hold the Ctrl key and click the Refresh button on my browser to update the templates.
Thanks
Mike

Mike,
The reason for this was that the machines that were used in training had Java SDK 1.5 installed if you are using 1.4 you cannot hold down the ctrl key to refresh the cache you must go into Tools -> Sun Java Console -> click the "X" key and that will clear the cache.

Cannot find procedures with dynamic pages

Hi all,
I have a problem with dynamic pages. cannot find procedures.
This is the content of a a dynamic page (example):
<HTML>
<ORACLE>
begin
htp.print(htf.bold(‘Fill in field values and use the push button to buy ticket’));
htp.br;
htp.formOpen(‘NETU.BUY_TICKETS’);
htp.teletype(‘Student Id___:’);
htp.formText(‘p_id’,5,5);
htp.br;
htp.teletype(‘Event Id_____:’);
htp.formText(‘p_eventid’,5,5);
htp.br;
htp.teletype(‘# of Tickets_:’);
htp.formText(‘p_no_of_tickets’,5,5);
htp.br;
htp.teletype(‘Credit Card’);
htp.br;
htp.teletype(‘AMEX,MC,VISA_:’);
htp.formText(‘p_cc_type’,5,5);
htp.br;
htp.teletype(‘Card #_______:’);
htp.formText(‘p_cc_number’,10,10);
htp.br;
htp.formSubmit(NULL,’Buy Ticket’);
htp.formClose;
end;
</ORACLE>
<HTML>
and try to call to this procedure ‘NETU.BUY_TICKETS’ for save form data in BD:
begin
insert into tickets (id, eventid, no_of_tickets,cc_type,cc_number, trans_date) values (p_id, p_eventid, p_no_of_tickets, p_cc_type, p_cc_number, sysdate);
exception when others then htp.print(‘SQL Error Message:’||substr(SQLERRM,1, 200));
end;
All compiled fine.
The problem exact is when i submit the form, cannot find procedure.
In browser address show this -> http://portal:7778/pls/portal/NETU.BUY_TICKETS
and in the body...

mmm ... what's wrong? where is the log? i find a lot...

I have tried your code and it works for me . Here are the steps and codes I have used to stimulate your process
1. Created the procedure
CREATE OR REPLACE PROCEDURE p_buy_tickets (p_id in number, p_eventid in number, p_no_of_tickets in number, p_cc_type in varchar2, p_cc_number in number) IS
BEGIN
htp.print('Processed Successfully');
EXCEPTION
WHEN OTHERS THEN
htp.print('SQL Error Message:'||substr(SQLERRM,1, 200));
END p_buy_tickets;
2. Granted 'Execute' privilge on this procedure to Public.
3. Created a dynamic page with the following code (same as yours except the schema):
<HTML>
<ORACLE>begin
htp.print(htf.bold('Fill in field values and use the push button to buy ticket'));
htp.br;
htp.formOpen('MY_SCHEMA.P_BUY_TICKETS');
htp.teletype('Student Id___:');
htp.formText('p_id',5,5);
htp.br;
htp.teletype('Event Id_____:');
htp.formText('p_eventid',5,5);
htp.br;
htp.teletype('# of Tickets_:');
htp.formText('p_no_of_tickets',5,5);
htp.br;
htp.teletype('Credit Card');
htp.br;
htp.teletype('AMEX,MC,VISA_:');
htp.formText('p_cc_type',5,5);
htp.br;
htp.teletype('Card #_______:');
htp.formText('p_cc_number',10,10);
htp.br;
htp.formSubmit(NULL,'Buy Ticket');
htp.formClose;
end;
</ORACLE>
<HTML>
4. I got the message 'Processed Successfully' when I ran the dynamic page and submitted the form.
You may need to check how you declared parameters in the procedure and how you supplied values when you run the procedure. In this case, I created the procedure with "No Default" value for all parameters , so I have to supply value for all parameters in the form otherwise I will encounter the 'Page Not Found' error.
Hope this helps!.

Dynamic Page Layout - Opportunity Product Revenue

Hi gurus,
I am trying to setup a dynamic template for "Opportunity Product Revenues"
I set it up successfully in the object. However, this data is exposed only as a related list of Opportunity and not directly. Now, when I go into the "Opportunity" customization, it only allows me to set up static page layouts, with no option to setup the Dynamic page layouts through the Related list.
Please help..

Hi Jonathan,
Many thanks for your response.
Our CTE is already on R19. We want to experiment and be ready when our PROD is upgraded to R19.
Can you help me with the requirement, if you have an idea please? I would really appreciate the help.
Thanks

In a dynamic page how to share variable between PL/SQL and javascript

For example, my dynamic page contains such PL/SQL codes:
<ORACLE>
DECLARE
info varchar(100);
rowid urowid;
procedure doDelete(
row_id in urowid
) IS
begin
Delete From xxx
WHERE rowid = row_id;
end doDelete;
BEGIN
Select name, rowid INTO info, rowid
From xxx Where xxx;
HTP.PRN(' <INPUT TYPE="button" VALUE="show value" onClick="alert(info);">');
HTP.PRN(' <INPUT TYPE="button" VALUE="delete" onClick="doDelete(_row_id);">');
END;
</ORACLE>
The variable 'info' and '_row_id' are correct, however the two HTP. sentence do not work. What's the problem?
What I want to do is to show all the records in TABLE A in a page. And at the end of each line (record), there' re a 'delete' and a 'update' button to let user operate on this record. Is this possible? I know form can do delete an update, but it can not show all the records in a page like what report does. Besides dynamic page, is there any other better choice? Report can do it?
One more question. In a report, I employed link on one field to a second report. It works well. But I want to open the second report in a new window when the link is click. Is this possible?
I was almost driven crazy by these :( I so appreciate if anyone can help.

The code written by you is insufficient for the funtionality you are trying to achieve. Below is a method to achieve the same.
Note: Used standard scott.emp table for the example which is located in my db provider schema.
Do the below modifications as per your local configuration
xxxxx -> Replace it with your Portal schema
yyyyy -> Replace it with your db provider schema
<<module_id_of_form>> -> Replace with the module id of form created in step 1 & 2.
First and foremost... oracle does not allows variables starting with '_'. So if you want to use it you have to place it in double quotes ("")
rowid -> illegal
"_row_id" -> legal.
However, I will advice you not to use variable names starting with "_".
Now lets get started...
1. Create a form on the table you are using in the dynamic page. Just have the update button. Remove the other buttons.
2. Get the module id of this form. Instruction for getting the module id:
a) Right-click on the form's run link and copy the shortcut
b) Get the value of p_moduleid parameter. This is your module id.
3. Create a procedure "save_action_details" in your db provider schema. This procedure will accomplish the delete operation on the record.
     CREATE OR REPLACE Procedure save_action_details(
     p_rowid IN VARCHAR2,
     p_action IN VARCHAR2,
     p_dyn_ref_path IN VARCHAR2,
     p_dyn_page_url IN VARCHAR2)
     is
     l_sto_session xxxxx.wwsto_api_session;
     begin
     l_sto_session := xxxxx.wwsto_api_session.load_session(
     p_domain => 'DynStore',
     p_sub_domain => 'DynStore_' || p_dyn_ref_path
     l_sto_session.set_attribute(
     p_name => 'rowid',
     p_value => p_rowid
     l_sto_session.set_attribute(
     p_name => 'action',
     p_value => p_action
     l_sto_session.save_session;
     htp.init;
     owa_util.redirect_url(p_dyn_page_url);
     end save_action_details;
Explaination: The above procedure creates a session and keeps the rowid and action in the session. This information is used by the below dynamic form to perform the necessary action. In our exampl, the action is always going to be delete so you may go ahead and hard code it, else leave it as it is.
4. Grant execute privilege on the procedure "save_action_details" to public.
sql> grant execute on save_action_details to public;
5. Create your Dynamic page.
a) In HTML code section have the below code. This code shows some columns from the table and "update" and "delete" buttons to perform the respective action.
     <ORACLE>select empno,ename,rowid,
     '<input type="button" value="Update" onClick="doAction(this.form,''UPD'',''xxx'','''
     || xxxxx.wwv_standard_util.url_encode(rowid) || '''); tWin();">
     <input type="button" value="delete" onclick="doAction(this.form,''DEL'',''' || rowid || ''',''xxx'');">' Action
     from yyyyy.emp</ORACLE>
b) In additional pl/sql code section of dynamic page, have the below pl/sql block "in after displaying the header" section.
     declare
     l_sto_session xxxxx.wwsto_api_session;
     l_del_rowid varchar2(20);
     l_action varchar2(10);
     begin
     htp.comment('User code starts here ...');
     htp.p('<script>');
     htp.p('var winHandle;');
     htp.p('
     function doAction(formObj, action, rowid, erowid)
          if (action == "UPD")
          var formURL = "' || xxxxx.wwctx_api.get_proc_path('wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=<<module_id_of_form>>&p_arg_names=_rowid&p_arg_values=') || '" + erowid;
          winHandle = window.open(formURL, "winDynUpd", "width=750,height=500,resizable=yes");
          else
          formObj.p_rowid.value = rowid;
          formObj.p_action.value = action;
          formObj.submit();
     function tWin() {
          if (winHandle.closed) {
          document.location = document.location;
          else {
          setTimeout("tWin()", 500);
     htp.p('</script>');
     htp.p('<form name="dynRowProcess" method="POST" action="'
     || xxxxx.wwctx_api.get_proc_path('save_action_details','yyyyy')
     || '">');
     htp.p('<input type="hidden" name="p_rowid">');
     htp.p('<input type="hidden" name="p_action">');
     htp.p('<input type="hidden" name="p_dyn_ref_path" value="' || p_reference_path || '">');
     htp.p('<input type="hidden" name="p_dyn_page_url" value="' || p_page_url || '">');
     l_sto_session := xxxxx.wwsto_api_session.load_session(
     p_domain => 'DynStore',
     p_sub_domain => 'DynStore_' || p_reference_path
     l_del_rowid := l_sto_session.get_attribute_as_varchar2('rowid');
     l_action := l_sto_session.get_attribute_as_varchar2('action');
     if l_action = 'DEL' then
     delete from yyyyy.emp
     where rowid = l_del_rowid;
     end if;
     end;
Explaination: The session information (rowid and action) stored by "save_action_details" procedure is retrieved by the dynamic page and is used to delete the record.
6. Once you are through with the above steps, test it by placing the above "dynamic page" portlet on a page.
a) When you click on delete button the record gets deleted and the automatically refreshed page will not show the deleted record.
b) On clicking update button, a form will appear. do the necessary modifications in data and click update. the data in the form gets updated. Once you close the form the dynamic page gets refreshed automatically and it will show you the updated information.

How to create a form based on table using dynamic page?

Hi,
I need to create a form using dynamic page. How do you pass values from the html form to a oracle procedure that will get executed on submission of the form ? I could not find any documents which shows how to do that. Can anyone please help me out with an example ?
thanks,
Mainak

Hi,
Something seems to get added to the form action because of "http". Hence I am removing it.
You need to write a procedure with the values in the as parameters. Say for example you want to insert a record into dept
table then
Dynamic page code
<html>
<body>
<form action="portalschema.insert_dept">
<input type="text" name="p_deptno">
<input type="text" name="p_dname">
<input type="submit" name="p_action" value="save">
</form>
</body>
</html>
Procedure code.
create or replace procedure insert_dept
(p_deptno in number,
p_dname in varchar2,
p_action in varchar2)
is begin
if p_action = 'save' then
insert into scott.dept(deptno,dname) values(p_deptno,p_dname);
commit;
end if;
end;
grant execute on insert_dept to public;
Hope this helps.

How to get page URL in a dynamic page in 10.1.4?

Does anyone know how to get the page URL in a Dynamic Page in 10.1.4 without using javascript.
I know that you can use a PL/SQL portlet and the portlet_record, but this is specifically for a Dynamic Page.
Regards
Jenny

Hi,
I am trying the suggested approach in 10.1.4 but unfortunatley I get the following error:
PLS-00302: component 'SHOW_INTERNAL' must be declared
In my Dynamic Page I have the following code
htp.p(cms_context.urlpage);
In the '... before displaying the page' I have the following
schema_name.cms_context.urlpage := schema_name.dynamic_page_name.show_internal.p_page_url;
Can anyone help?

How to get form fields in a dynamic page as a portlet

I have a dynamic page(publish as portlet and added to a portal page) with a html form that has many radio button created dynamically (query a table and create as many radio button as records I found) and the name of each radio button is the id of the record from the table it represents.
When I click the submit button of my form it will recall the same portal page and then I have to check which radio buttons where selected to update the database depending on it.
The problem is that I can't get the radio buttons inside the dynamic page because they are created dynamically so I can't make them portlet parameters to be associated with page parameters.
So How can I tell which radio buttons have been selected?
Please help me.

Hi,
Write a procedure which will be called as the form action. This procedure should take an array of parameters like p_arg_names and p_arg_values. For example
<html>
<form>
<input type="checkbox" name="p_radio">
<input type="checkbox" name="p_radio">
</form>
procedure submit_form(p_radio in wwv_utl_api_types.vc_arr)
begin
for i in 1..p_radio.count
loop
htp.p(p_radio(i));
end loop;
wwv_redirect.url(<page_url>);
end;
Hope that helps.
Thanks,
Sharmila

Retrieve data from a dynamic page via loadURL

Hello.
I would like to ask you how it is possible to retrieve data
from a dynamic page (asp classic in my case) using the loadURL
method.
I would like to create an html authentication form (with
username and password fields). The loadURL method should call an
asp page and then pass to the usual function 'DoIfSucceded' the
results of the elaboration.
Of course I'm going to have a switch in the function in order
to make different actions depending from the results of the asp
page (authentication succeded or failed).
I had a look to the examples at this page:
Adobe
samples
Is there anyone who can explain clearly how the results data
must be written by the asp page and how the success function can
retrieve them ?
I thank you in advance for your help.

loadURL() uses the the XMLHttpRequest Object so if the
content you return is XML, you have 2 choices for accessing your
data. You can either access it as a text string via the
XMLHttpRequest object's responseText property, or as a DOM document
via the XMLHttpRequest object's responseXML property:
function MySuccessCallback(req)
// If my data is XML, I can access the data that was sent
from the server
// as DOM elements via the XMLHttpRequest's responseXML
property.
var xmlDOM = req.xhRequest.responseXML;
// OR, you can access the data sent back from the server as
text via
// the XMLHttpRequest object's responseText property.
var xmlAsAString = req.xhRequest.responseText;
var req = Spry.Utils.loadURL("GET",
"/app/book.php?id=1&code=54321", true, MySuccessCallback);
If your serverside script wants to use some other format as a
response like JSON or plain text, then you can only access the data
as text via the responseText property.

Error creating dynamic page in an application with a schema other than portal30

Running 9iAS 1.0.2.2 on Solaris.
Database 8.1.7.1
I cannot seem to create a default dynamic page (select 'x' from dual) in an application that has a schema (e.g. test) other
than portal30. The error seems to be when portal tries to compile the dynamic-page package, it references itself from
within the package but prefixing the call with the other (test) schema. It never seems to compile? What seems to be the
problem? Any ideas?

If you are using any database object other than the applcation owned,then it has to be prefixed with the schema owner.
For example,
if the application schema is based on the schema "schema1" (say)
and your query is based on one of the object on "schema2"
and if you have necessary privilegves to access that object from schema2, then the compiler wont throw any error.
Can u explain, what u problem you are experiencing in detail?
(Also, if u give me the portal version, I can cross-verify that).
