Passing parameters based on events

Hi,
I want to pass the parameters between portlets on a
particular event e.g. onClick() or onChange(). The example which
is given in PDK is not useful in such a scenario. How can I use
htmlFormActionLink in this case ?
Thanks In Advance,
- Chetan

Chetan,
You can use javascript to dynamically submit the form.
Lets say you have a button (which is not submit button) and
onClick event of it should pass some parameters to the portlet.

<form name="custform" method="post"
action="http://.../servlet/page">


<input type="button" name="ok" value="ok"
onClick="javascript:document.custform.submit();">
</form>

Passing parameters to an event handler

I am successfully using event handlers to respond to user
inputs(mouse click, enter key, etc.)
The handler can also use the event objects parameters to
perform operations based on who called the function. An example of
this is the target._name, which is apparently passed when the event
occurs.
In addition, I have a need to call an event handler from
within AS to essentially mimic a mouse click or keyboard entry.
This call from AS is no problem. Just use the event handler
name. For instance, mc.click(); and the handler is invoked.
However, with the AS call there is no object passed to the
handler. This differs from an event-driven call where an object
identifying the event source is passed to the handler.
The question is: Can you pass a parameter(s) or object to an
event handler from a call in ActionScript? I have tried various
ways, but nothing has worked.
Does anyone know the insides of event handling and how the
"eventObject" is passed when
a user event occurs? Knowing how that works might give some
clues as to how to pass an object from an AS call.

You would need to use a modified version of the
mx.utils.Delegate package. The link below has just that;

Pass parameters to a function in main class from loaded SWF?

I've got a main.as that loads SWF to the stage.
the loaded SWF seppoused to pass a link to the main.as and trigger a javascript function to popUp that photo from that link.
I know there are two ways:
((root as MovieClip).parent.parent as Object).somefunction(parameters);
and to dispatch an event.
inorder to pass parameters throug the event i need to extend it with another class.
isnt the (root as... ) more efficient if all i need is to pass a link?

when a photo from the gallery is selected a javascript popUp shows it enlarged with additioan editing options (kinda like in facebook).
in that popUp ther is also a next button so its kinda bidirectional. (the next calling the loaded SWF throug main to get the next link in the photo array)
the photo is a grandchild of a grandchild of the stage and the loaded swf is a grandchild so using:
((root as MovieClip).root as MovieClip).ExternalInterface.call("ShowPic", link);
is discusting ><

Passing Parameters to Procedure based sub report thru JRC

Hi
I am using storedprocedure based main report with a subreport and i am trying to invoke these reports with JRC.
I am passing parameters to main report then it is asking parameters for subreport then i placed following statement by placing subreport name
param2.setReportName("detailed_aging_report_wk.rpt");
but after using this statement it is prompting for main report parameters.
How i can pass the same parameter values to both main and sub reports?
Thankyou.

Here is a snippet code that demonstrates how to pass a parameter to a subreport, you can accommodate it and test it and see if you still have the same behaviour. What you need to do is to add the code to set the parameter of the main report.

How to pass context based parameters to subquery?

Hello to All!
How to pass context based parameters to subquery of custom folder when I schedule workbook?
Thanks, Oleg

Hi Russ
Yes, I've done this too. Basic SQL though will not allow the updating of a table inside a function, so we have to get clever. The trick is to use the PRAGMA AUTONOMOUS TRANSACTION command. Here's an example:
FUNCTION UPDATE_MYTABLE(P_VALUE IN NUMBER)
RETURN VARCHAR2 IS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
UPDATE SCHEMA_OWNER.MY_TABLE SET MY_VALUE = P_VALUE;
COMMIT;
RETURN('Done');
END UPDATE_TABLE;
When the update has been completed the Discoverer worksheet will respond with 'Done'.
Everyone: don't forget to grant EXECUTE on this function to all of the necessary users, including the EUL owner, and also don't forget to import the function using the Admin edition so that it is available for the users. You will also need to make sure that all necessary users have been granted the UPDATE privilege on the table.
I hope this helps
Regards
Michael

Passing parameters to web based oracle forms

Hi,
How can I pass parameters from web page to oracle form applet? OR is there anyway i can know (within a form) if that form is run from a client/server or from web. This is just to set some parameters depending on the condition: client/server or web application.
thank you

To know if you are on the Web use the get_application_property built-in, check out the online help for it.
To pass parameters - if you are using the forms servlet you can pass parameters on the URL that calls your Forms application.

How to open a page from a Form and pass parameters to the form on that page

I found a similar example on this forum, but it did not work for me:
declare
l_names owa.vc_arr;
l_values owa.vc_arr;
i number;
begin
PORTAL.wwpro_api_parameters.retrieve(l_names, l_values);
FOR i in 1..l_names.count
LOOP
htp.p(l_names(i) || ' ' || l_values(i));
END LOOP;
end;
By using this method i get the parameters for the Form, like the session ID, but not the parameters for the Page that the form is displayed in.
Another method I tried:
To open a Form from a Form and pass parameters works fine like this:
--In the After processing page PL/SQL event.
declare
v_id number;
blk varchar2(10):='DEFAULT';
Begin
v_id:=p_session.get_value_as_number (p_block_name=>blk,p_attribute_name=>'A_ID');
if v_id > 0 then
htp.formOpen('PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=2649500412&p_arg_names=_show_header&p_arg_values=YES&p_arg_names=ID&p_arg_values='||to_char(v_id),'post');
htp.formSubmit(NULL,'Upload Files');
htp.formClose;
end if;
End;
But I want to open a Page containing the Form instead of just opening the Form. Is this possible to open a Page and pass paramters to the page, and then let the form inside the Page access the passed paramters. The reason for this is that a Form cannot be based on a page template, or can it? When opening the form i want to keep the left menu, which I can if it is a page based on my template with the left menu.
Best regards
Halvor

Hi,
You can do this by calling the url of the page with the form. You can then use p_arg_names and p_arg_values to pass parameters. In the called form you can get the value from p_arg_names and p_arg_values and assign it to the form field.
You can call this code in the success procedure of the calling form.
declare
v_id number;
blk varchar2(10):='DEFAULT';
v_url varchar2(2000);
Begin
v_id:=p_session.get_value_as_number (p_block_name=>blk,p_attribute_name=>'A_ID');
v_url := <page_url>;
if v_id > 0 then
call(v_url||'&p_arg_names=id&p_arg_values='||v_id);
end if;
End;
In the called form in "Before displaying form" plsql section write this code.
for i in 1..p_arg_names.count loop
if p_arg_names(i) = 'id' then
p_session.set_value(
p_block_name => blk,
p_attribute_name => 'A_ID',
p_value => p_arg_values(i)
end if;
end loop;
This code picks up the value from p_arg_values and assigns it to the form field.
Hope that helps.
Thanks,
Sharmila

Oracle JSF portlet Bridge - Passing parameters to Portlet

Hi All,
I am referring following link to pass parameters to portlets that are created from TaskFlow.
http://sqltech.cl/doc/oas11gR1/webcenter.1111/e10148/jpsdg_bridge.htm#CACCJCAA.
I am able to pass values to portlet by having setters for respective navigation parameter exposed in oracle-portlet.xml file
Now, how to invoke the method in a portlet that will make use of the passed values and do further processing. The method would be same as getEmployees() mentioned in the tutorial above. But the getEmployee method is not invoked event after doing all the event mapping.
Regards,
Sanjay

AH, if you are using ADF faces than the risk gets smaller. If you are used to eclipse and you developer your ADF application there than i see a good chance for succeeding later on.
You might have small issues when migrating to JDeveloper but i don't think they will be blocking.
If you are working with lots of WS, have you looked at the different types of mash-ups you have in WebCenter?
For example the omniportlet which allows you to integrate webservices and style the parameter forms and output.
You can also create data controls at runtime in Webcenter that are based upon webservices.
There aren't many cases available. Maybe you should come to OOW in October (if that isn't to late). There will be some customers presenting their use cases there.

Passing parameters in jsp

Hi friends,
I am very new to oracle pdk. But unfortunately i was assigned to a small pdk development using jsp.
How can i send parameters in the Oracle jpdk multipage sample portlet .
The first.jsp says ,
<%
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
NameValuePair[] linkParams = new NameValuePair[1];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "next_page"), "/htdocs/multipage/second.jsp");
%>
<center>
Hello, this is the first page<p>
<%=UrlUtils.constructHTMLLink(prr, UrlUtils.PAGE_LINK, "second page", "", linkParams, true, true)%>
</center>
Now where should i add the parameter which i have to send to the second page named second.jsp.
In the same way how to receive the parameter values in the second.jsp file, the second.jsp is listed here as below.
<%
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
NameValuePair[] linkParams = new NameValuePair[1];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "next_page"), "/htdocs/multipage/first.jsp");
linkParams[1] ="a=hello";
%>
<center>
Hello, this is the second page<p>
<%=UrlUtils.constructHTMLLink(prr, UrlUtils.PAGE_LINK,
"first page", "", linkParams, true, true)%>
</center>
Please write to me an example in detail.
Matter is very urgent.

I just recently put a set of helper classes on my knowledge exchange site specifically to help with passing parameters via the url.
http://portalstudio.oracle.com/servlet/page?_pageid=2106&_dad=ops&_schema=OPSTUDIO&_type=site&_fsiteid=233&_fid=433232&_fnavbarid=180376&_fnavbarsiteid=233&_fedit=0&_fmode=2&_fdisplaymode=1&_fcalledfrom=1&_fdisplayurl=
I called it Portal Tools. It includes usage documentation.
but, to stick with the code example you provided,
Technically, you can pass parameters at least three different ways:
-Using portal's parameter-event processing (portlets interact with portal for parameters)
-Using qualified parameter names (portlets only see "their" parameters)
-Using unqualified parameter names (portlets are responsible for unique names, name collisions, etc)
I would generally shy away from the unqualified parameter method; it was put in to support older versions of portal.
The example you provided currently uses qualified parameters, so I will answer with that method.
To add a parameter "a" with a value of "hello",
change the setup of the link parameters in first.jsp to this:
NameValuePair[] linkParams = new NameValuePair[2];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "next_page"), "/htdocs/multipage/second.jsp");
linkParams[1] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, "a"), "hello");
note that in the definition line, you must allocate space for EXACTLY how many parameters you are using (2 now, rather than 1). Then in the assignment lines, it is using java standard ZERO based indexing, so the new second parameter is at index 1.
to get (and display) the parameter in the second.jsp page, you would include something such as this:
Parameter "A" contains a value of <%= prr.getParameter("a") %>.
note how you just ask the PRR for the parameter with the unqualified name.
The "next_page" parameter is defined (in the provider.xml) to be used by portal to manage page flow and display. That is why you only have to set the "next_page" parameter.
I hope this helps.

Passing Parameters to iView

Hello Experts,
I want to pass a simple parameter from one iView to another. How do i pass it using EPCM.doNavigate? my code in asp is
Response.Redirect("url to navigate" + "?ID=V")
Request.QueryString\["ID"\] == "V"
I do some validations based on this querystring.
I need an equivalent for this in portal. I skimmed through many earlier posts but din't get a proper solution. Could you plz help me out with the simplest possible way ASAP.
Regards,
Madhesh
Edited by: Madhesh P on Jan 7, 2008 5:21 AM

Hi Madesh,
You can use custom events for passing parameters from one iView to Other.
Or
If the parameters are to be used in more than one iView you can use session variables.

Passing parameters between portlets (PL/SQL PDK)

I'm new to the PDK, so forgive me if this is a dumb question. I need to develop a portal page containing a single search portlet, and then many other associated portlets which bring back various bits of data based on the result of the search.
Is it possible to drive the content of other portlets on the same page by passing values from one to another and refreshing the whole page?
null

Neil,
You can definitely pass parameters from one portlet to another in PL/SQL and we actually have a sample that you can take a look at. In the PDK, download the Parameter passing and CSS Example Provider sample. http://technet.oracle.com/products/iportal/files/pdkjan/index.html
Click on PL/SQL
One of the portlets demonstrates how to pass parameters to one portlet or all portlets on a page.
Hope this helps,

Types used in this fashion, only make sense if the table is based on the type. It makes very little sense to have a table structure and then to duplicate the structure using a type.
The 2 structures may be defined the same. But they are NOT interchangeable and requires one to be converted to the other to use. This is not sensible in my view. It is far easier in that case to simply use the PL/SQL macro +%RowType+ to create a duplicate structure definition - one that can natively be used for touching that table, without conversions required.
If you do want to use types, define the type, then define the table of that type, adding the required constraints (pk, fk, not null, check) to the table's definition.Billy:
Just curious, why do you say it makes very little sense to have a type modeled on a table? I do that a lot. In my case, I am getting the values from an external program, not building them manually, but it makes a lot of sense to me.
One application where I do this a lot has a java front-end that parses HL7 messages. Each message contains at least minimal information about a variable number of entities (and often several rows for an entity) in the database, and must be processed as a single atomic trasnaction. So, rather than have potentially hundreds of parameters to the "main" driver procedures for different message types I created a set of types more or less identical to the tables representing the entities. The java program parses the mesasge and populates the type, then calls the appropriate stored procedure for the message type passing in the populated types. My stored procedure then does inserts/updates or deletes as appropriate over potentially dozens of tables.

Passing Parameters via Post Method from Webdynpro Java to a web application

Hello Experts,
I want to pass few parameters from a web dynpro application to an external web application.
In order to achieve this, I am referring to the below thread:
HTTP Post
As mentioned in the thread, I am trying to create an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.
But when I build my DC, I am getting the same error which most of the people in the thread have mentioned:
Controller XXXCompInterfaceView [Suspend]: Outbound plug (of type 'Suspend') 'Suspend' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'.
I am using SAP NetWeaver Developer Studio Version: 7.01.00
Kindly suggest if this is the NWDS version issue or is it something else that I am missing out.
Also, if it is the NWDS version issue please let me know the NWDS version that I can use to avoid this error.
Any other suggestion/alternative approach to pass the parameters via POST method from webdynpro java to an external web application apart from the one which is mentioned in the above thread is most welcome.
Thanks & Regards,
Anurag

Hi,
This is purely a java approach, even you can try this for your requirement.
There are two types of http calls synchronous call or Asynchronous call. So you have to choose the way to pass parameters in post method based on the http call.
if it is synchronous means, collect all the values from users/parameters using UI element eg: form and pass all the values via form to the next page is nothing but your web application url.
If it is Asynchronous means, write a http client in java and integrate the same with your custom code and you can find an option for sending parameters in post method.
here you go and find the way to implement Asynchronous scenario,
