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?

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,
Sue

Passing parameters between portlets with in the same page

Hello,
I have created a Form and a report. The form allows a user to make some selection values, and then upon submit it passes the selected values to the report to query the database. The results from the query are displayed in a new - seperate - window from the form. Is there anyway to disaply the report results on the same page as the form that called the report? I guess I am trying to have a page with 2 portlets (a form, and a report). I want the user to be able to make a selection from the form portlet and pass that selection to the report portlet within the same page.
Thanks,
McKell

Hi I received this info from an OSS named Mahantesh. I thought it was very helpful information for passing portlet parameters between a form and a report within the same page.
Please check these steps to pass parameter from form to report:
This article is based on demo tables EMP and DEPT.
1. Create a report RPT_DEPT using the query 'Select * from dept where deptno= :deptno'
2. Create a form FRM_EMP based on EMP table.
3. Edit the form FRM_EMP => 'Formatting and Validation Options' section => click on DEPTNO field
=> Give the value for the 'Link' (under 'Display options') as 'javascript:runrep()' where runrep is the name<br>
of javascript function that we are going to create later.
4. In 'Form text' section, in the 'Footer Text' add the code for the runrep function as follows.
<script>
function runrep()
var formObj = document.forms[0];
var deptno;
for (var i=0; i < formObj.length ; i++){
if (formObj.elements.name == 'FORM_EMP.DEFAULT.DEPTNO.01'){
//FORM_EMP is the form name
deptno = formObj.elements[i].value;
break;
var url="/portal/page?_pageid=38,1,38_31678:38_31787&_dad=portal&_schema=<br>
PORTAL&deptno=" + deptno;
//modify the url according to your environment.<br>
window.location=url;
}<br>
</script>
5. Modify the URL in the above code with your page url on which form and report portlets have been placed.
6. Goto Page properties => Parameters tab (Parameters and Events option should have been enabled at Pagegroup level).
7. Create a page parameter and map it with report portlet parameter.
8. Now run the page, enter deptno or query the form to get the deptno and click on the link next to deptno field. You should get report with corresponding deptno on the page.

Passing parameters between portlets

Hi , I have a page with two portlets : one , done with the wizard , is a form , the other one is another form , but is done with a JSP.
My trouble is that with the second form , the one done with a JSP , I must insert into the database two values , one retrieved by the jsp itself , and the other one is a value of one field of the other form.
My question is how can I get , from my jsp , that value coming from the other portlet ???
Thanks

Hi,
You can redirect to another page and pass parameters to it. For this, you need to know the pageid to which you have to redirect. Assign form action to
http://machine:port/servlet/page
PageServlet requires few other parameters (form fields) to redirect the control to the required page.
You can get them by making a call to
HttpPortletRendererUtil.htmlFormHiddenFields(pr,PortletRendererUtil.PAGE_LINK)
This returns a string similar to the following.
<INPUT TYPE="hidden" name="_pageid" value="54" />
<INPUT TYPE="hidden" name="_dad" value="portal30" />
<INPUT TYPE="hidden" name="_schema" value="PORTAL30" />
Parse it for _pageid and change the value to the page you want to redirect. Print these contents inside your form. Once you submit the form, it'll redirect the control to the page you want with the parameters.

Passing Parameters between Portlets or pages

Hi,
How can we pass the data from a Portlet in one page to another Portlet in a different Page??
Requirement: I want a portlet which should take some parameters(basically a form),On submit should process the parameters and should forward the result to a Portlet in another page.
Regards
Yash

Yash,
You could use session variables to save information that can be used during the browser session. Example would be the form asks a user for their nickname. The user types in his nickname and hits the submit button. The form will then save the info in a session variable. Then any other portlet can open that session variable and get the info and use that info. Now if the browser is closed, the info in the session variable is lost. Check out this link:

Passing parameters between portletized ADF Faces applications, possible?

Hello,
In the developer guide, section 4.5.3 (http://download-east.oracle.com/docs/cd/B32110_01/webcenter.1013/b31074/jpsdg_pages.htm#CHDGGCGE) it says that you can synchronize portlets using an ADF Faces component value. However, that example do not use a value coming from a real portlet, the parameter come from a selectOneChoice define in the container page.
Is there a way to achieve the same thing but with the selectOneChoice being placed in the WSRP 2.0 portlet? Basically the communication scheme is WSRP 2.0 to WSRP 2.0 which is something possible using URL parameters. However, the problem with JSF components is that they pass their values through a JavaScript launched POST submit so the values are never added to the URL and even worst, you cannot be sure of the generated parameter name as it depends on the context in which the component exists (mainly the presence of a parent NamingContainer) and the only way to know that parameter name for sure is to have a way to call component.getClientId(facesContext) which is impossible for the portlet container and therefore for the other portlets.
To put it shortly, is there a way to send a navigation parameter from a portletized ADF Faces application to its container page beside using goButton and goLink (we need to keep the action/actionListener functionality)?
Regards,
Simon Lessard

Can someone explain how to assign a value to a parameter in JSF like in the ParameterFormPortlet source code? Something in replacement of this :
    if (viewMode)
      // Set the new parameter values. These will be intepreted by the
      // container as navigational parameters as the names match the names of
      // the declared parameters.
      actionResponse.setRenderParameter(PARAMETER1, param1);
      actionResponse.setRenderParameter(PARAMETER2, param2);
      actionResponse.setRenderParameter(PARAMETER3, param3);
    }I mean, how to replace setRenderParameter to achieve the same thing inside a JSF binding bean for example. Is it possible via the PortletContext?
Thanks in advance for any hint.

Passing parameters from portlet reports to portlet forms

Hi,
I'm tring to pass parameters between a Report displayed as a portlet in a page ( page 1) and a form displayed in other page ( page 2).
The problem is i can't do this.
I only can pass parameters from a report ( running as normal or in a portlet displayed in a page) to a form running "normal" by using application links. Can i do this between a report that show's me every employees of scott.emp table. Then when i click on each employee, it open's me another page with the portlet form of the specified employee.
I'm not sure i made myself clear. Please send me some feedback.
Pedro

I have the same problem. Please let me know if this could be done.
In particular my form is a type of "Form on Table/View."
Thanks

OBIEE 11G - Issue passing parameters between two reports

Hi folks,
I am struggling to pass parameters between two reports in OBIEE 11G.
My first report contains the following columns: Rolling Year Type (VCHAR), Year(VCHAR), Month(VCHAR), Cost(Double).
My second report contains the following columns: Rolling Year Type(VCHAR), Year(VCHAR), Month(VCHAR), Category(VCHAR), Cost(Double).
My requirement is to pass the Rolling Year Type, Year and Month values from report 1 to report 2.
On the Month column properties of report 1, I have created an Action Link called 'Drill to Category'. I have clicked on 'Navigate to BI Content' and selected Report 2.
Then on Report 2, I have included three filters: Rolling Year Type is prompted, Year is prompted, Month is promted.
When I run the report I always get the following error:
The specified criteria didn't result in any data. This is often caused by applying filters and/or selections that are too restrictive or that contain incorrect values. Please check your Analysis Filters and try again. The filters currently being applied are shown below.
When I check the cursor cache, the filter values are correct. Does anybody have any idea why Report 2 does not display?
When I remove the Month filter, the report works correctly.
I have since changed the third filter to be Month No and although Report 2 does display, it does not pick up the filter on the Month No.
I initially thought this may have been a caching issue and so I have disabled BI Server Cache but this does not fix my problem.
This was never an issue on OBIEE 10G as I found it very easy to navigate between two requests.
Has anyone else experienced problems with passing parameters between two request in 11G?
Any help appreciated.
Thanks
Gavin

Hi,
I once tried this kind of requirement(with dashboard prompts though) and hit at similar issue. I later found out that the problem is with the space in the parameter values. Can you please let me know, if the same is the case with you?
Suppose the parameter passed is "Jan 2010", but the report on the destination takes the value as "Jan" & "2010". Yes, it kind of split the parameter value to two based on space. I think we can notice the filters the destination report got, by enabling filter view.
In this case, since you pass only value at a time, could you try placing the parameter value anyway in double quotes? I think the Server then will understand it as one value.
Thank you,
Dhar

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.

Help is needed.

can you put that stuff in the session context in the first page, then pull it out in the second page?

How to pass Parameters between two forms

im trying to do this but i could not find any way for this.
can any one help me how can i pass parameters between two forms

Global variables can be used, but you can do what the online help
says ...
Parameters are passed to called forms by means of a parameter
list. A parameter list is a named programmatic construct that is
simply a list of parameter names (called keys) and their values.
You can pass parameter values to forms invoked by the built-in
subprograms CALL_FORM, OPEN_FORM, and NEW_FORM. In addition, you
can pass parameter values to other Oracle tools with the
RUN_PRODUCT procedure.
A parameter you include in a parameter list can be either a text
parameter or a data parameter. The parameter type determines how
its value is interpreted.
Text Parameters The value of a text parameter being passed to a
called product is a CHAR string that can represent the following:
n a user-defined form parameter defined in a form invoked
by the CALL_FORM, OPEN_FORM, or NEW_FORM built-in subprograms
n a command line or user-defined parameter for a product
invoked with the RUN_PRODUCT built-in subprogram
Data Parameters The value of a data parameter being passed to a
called product is always the name of a record group defined in
the current form. (A record group is a data structure that
stores records derived from a query or through programmatic
assignment.) Data parameters are used to pass data to products
invoked with the RUN_PRODUCT built-in subprogram. You cannot
pass data parameters to forms.
The following table shows the structure of a parameter list that
contains four parameters:
Key Paramtype Value
CITY Text_Parameter 'BOGOTA'
CATEGORY Text_Parameter 'EXPORTS'
MULTIPLIER Text_Parameter '.0275'
NEW_DATA Data_Parameter 'RECORD_GROUP8'

Trying to pass parameters between GUI classes and methods

Hi All.
I have been working on a rather large final year project in college and it is getting close to the deadline. It looks as though I need to "tidy up" my code as it contains too many static methods, variables and other bad programming habits. My package consists of many different GUI's and classes. Up until now I have been calling different GUI's with guiName.NameOfMethod. I have been told this is bad practice so I am trying to fix this. Also instead of passing parameters correctly I have been creating static variables in my main class and using them. So for example if one class needed to pass a variable to the other I would first myGlobalVariable = X; in the first class. And then the second class can use this. This is also bad, right?
So I guess im really just looking for a good example or tutorial on how to pass parameters between classes and methods, GUI if possible. Here is an example of how my GUI classes look:
public class anotherGUI extends JFrame implements ActionListener {
        private JTextField a, b, c;
        private JButton button1, button2;
        JPanel p, p1;
        public anotherGUI() {
            LayOutAnotherGUI();
            setLocationRelativeTo(DnDMain.pictureArray[a]);
            setTitle("Example");
            setVisible(true);
            pack();
        private void LayOutAnotherGUI(int c) {
     //GUI is layed out here
        public void actionPerformed(ActionEvent e) {
            Object source = e.getSource();
            if (source == submit)
                clickOK();
        public void clickOK(){
            //Here is where I have been accessing and modifying static global variables. (But this needs to change).
public void showanotherGUI() {
        new anotherGUI();
}This is more or less how I have been going about creating my GUI's. These are used as pop ups. The user enters a value and then it is closed.
To be honest I have been able to pass a variable correctly from one class to a GUI class but I have still having difficulty. For example in my code above I can pass the variable into this class but I cannot pass it into clickOK(). An this is where it is needed.
Can anyone please help?
I hope I have explained my problem well.
Thanks in advance.

I dont think that is what I need. An example of what I do in my program is:
I have a main GUI with an array of images. There are a number of other small GUI's that appear for certain functions when the user clicks on an image or does some other function. I am trying to pass a value into the GUI class that is used for the smaller "pop up" GUI. So lets say the user has clicked the image in array[12]. Then a GUI is displayed. I need to pass the integer 12 into this class.
Thanks.

How to pass parameters between main and sub vi during parallel execution using the VI server technique?

Hello All,
I am working with the following example (from previous postings on this
board) that demonstrates how to run a sub vi in parallel with the main
vi. I'd like to pass parameters between the main and sub such as
the control (delay) and indicator (value) parameters of my subvi
example. Does any one know how to do this? Parallel
execution is important for me, I cannot just paste the subvi icon into
my main diagram (two nested while loops...)
Many thanks,
Luis

Luis, you can use the VI Server methods 'Set Control Value' and 'Get Control Value', as demonstrated in the attached examples.

Passing Parameters between 2 Portlets on 1 Page

Hi,
I'm new to this portlet stuff and I might miss something important, but:
I "just" want to send parameters from one form on one Page to a portlet on the same page...
PassAllParameters is already set to true...
I also have read the "Primer" and the "Adding Parameters and Events to Portlets", after giving up to do this my own, I just copied and pasted the Name/Age Form JSP (nearly... I've made Java out of it...) as my DataProvider Portlet and copied and pasted the "Generic Public Parameter Receiving Portlet" as my DataReceiver Portlet... the Event and Parameter Tags are NOT missing in the provider.xml... but even after pressing submit there are no parameters at all avaible for the "receiving Portlet"!!!
PLEASE can someone tell me what I am doing wrong?!?!?!?

Hi friends,
I worked with the application which is in
http://server:port/jpdk/providers/event. is working fine with passing parameters to another page.
Also I create my own application which is working fine if i have the 2 portlets in the same page.
But it is not working with portlets in different page. On clicking the link it is not going to the another page. Hereby i give the required codes.
portletpass.jsp:
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
String eventSubmit = EventUtils.eventName("submit");
String eventParamsno = EventUtils.eventParameter("sno");
String strsno="50" ;
NameValuePair[] linkParams = new NameValuePair[2];
linkParams[0] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, eventSubmit), "");
linkParams[1] = new NameValuePair(HttpPortletRendererUtil.portletParameter(request, eventParamsno),strsno);
<a href="<%=PortletRendererUtil.constructLink(prr,
prr.getRenderContext().getEventURL(), linkParams, true, true)%>"><%= strtitle %>
</a>
provider.xml of portletpass.jsp:
<event class="oracle.portal.provider.v2.DefaultEventDefinition">
<name>submit</name>
<parameter class="oracle.portal.provider.v2.DefaultParameterDefinition">
<name>sno</name>
<displayName>sno</displayName>
</parameter>
</event>
portletreceive.jsp:
PortletRenderRequest prr = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
//      String snosp = "sno", snorec="" ;
//     String values = prr.getParameter("sno") -------returns null
     String values = prr.getParameter("_page_url");
     String snorec = values.substring(values.lastIndexOf("sno=")+4) ;
     out.println(snorec); // here i get the required value
provider.xml of portletreceive.jsp:
<inputParameter class="oracle.portal.provider.v2.DefaultParameterDefinition">
<name>sno</name>
<displayName>Input Parameter #1</displayName>
</inputParameter>
Also i did the necessary changes in parameters and events tab as well.
I cant sorted out what is the mistake i did.
The scenario i need is on clicking the link it should display the details in a new page.
Can anybody please help me.
Thanks in advance
