Passing parameter to group of portlets on a page from 1 report

Hello Forum,
Portal 3.0.7
I have a page (page 2) that contains three portlets, each is a single report (Reports b, c, and d). They all query based upon the same parameter value. I have a different page (page 1) that contains a report (report a). I want to setup a link in report a that calls page 2, passes the parameter value to reports b,c,and d. With the reports b,c, and d reporting based upon the parameter value.
Does anyone have any ides on how to do this? I have been successful in the past using forms based upon procedures to share a parameter amounts several portlets on a single page. But I have no idea how to call a page, pass the parameter and refresh the page in one step.
Thanks in advance,
Andre'

You should concatenate to the url of the page wich contains the three forms with somthing that is near to the following :
'&parameter_name='||parameter_value
as many times as you have parameters in the portlets on the page.
then you should call the new url
hope that this could help you

Passing parameter in href to a different Portal page

Hello All,
I have requirement where I have a portlet A in portal page 1. Portlet A is a JSP which has a href pointing to the url of a different portal page (page 2) having the portlet B.
<a href=".../pls/portal30/url/page/page2
When I click on the link on portlet A, I need to pass some parameters to the portlet B in second page.
I know there's no straight forward way to do this. Could you all please share me your experiences and advice me asap.
Thanks in anticipation.

I have an example of two portlets on the same page and parameter is passed from one
to another. The idea should be the same
is the other portlet in on another page.
Hope this helps.
Report 1: summary report
SQL report, on scott.dept:
select htf.anchor('http://iasqa-ultra1.us.oracle.com:7777/servlet/page?_pageid=117&_dad=wwv_30898&_schema=WWV_30898&_mode=3&dept='| |deptno, deptno) aaa, dname, loc from SCOTT.dept
The url here is the page url with extra parameter for dept, the bind variable
in the detail report
Report 2: detail report
SQL report, on scott.emp
select * from scott.emp where deptno = :dept
Add the following PL/SQL code in the "before displaying the page"
wwv_30898.wwv_name_value.replace_value(
l_arg_names, l_arg_values, p_reference_path| |'.dept', wwv_30898.wwv_standard_util.string_to_table2(nvl(get_value('dept'), 10)));
Build a page and include these 2 portlets, then when you click
on the link of the summary report, the page will be refreshed,
and the detail report changed based on the data from the summary report.
Here is the url for my example,

How to pass parameter to the method in EJB session bean from Managed Bean

Hi,
I need some guidance in accessing the EJB session bean methods from one of my backing Bean. I use EJB 3.0 Entity Beans and EJB Session Beans. I have to get value from my page and pass it thro the backing bean to the respective EJB session bean. I have no clue of how to do this,
When i click a command link on the page, in its backing bean click method, i am able to get a value and store in a variable under its click action. But from there i am not knowing of how to pass it as a variable to the EJB session bean and hence execute the query(this is where we have to pass the variable as a parameter in its where clause) in the entity bean.
I wanna know how to make a call to the EJB session bean and from there execute the Enitity bean.
Guide me regarding this....
Thanks
ri

Unfortunately dependency injection doesn't work for jsf backing beans, so you have to use a normal jndi lookup to find your session bean. The following example shows you how to find a session bean and call a method:
public void commandButton_actionListener(ActionEvent actionEvent) {
Context ctx;
try {
ctx = new InitialContext();
helloWorldEjb = (HelloWorldEJB)ctx.lookup("HelloWorldEJB");
hello = helloWorldEjb.sayHello(name);
System.out.println(hello);
} catch (NamingException e) {
e.printStackTrace();
}

Passing parameter for the bean function that deletes record from DB

I need to delete some record from the DB without updating the reset of the user screen.
I use commandButton with immediate attribute as true, because validation should be skipped.
So, I can't rely on backing bean values being updated, but need to pass a param to the function that does the delete (deleteTemplate) function below.
The value of this param is selected value in another comboBox called "template".
Code below is not parsing. Could you advise how to do it?
<a4j:commandButton id="deleteTemplate" value="Delete"
 action="#{qtBeanParam.deleteTemplate(param['piPerformanceReturnsForm:template'])}" immediate="true" reRender="template,templateList,templateOwner,templateOwnerList"
 styleClass="blue-button">
 </a4j:commandButton>Error Parsing: #{qtBeanParam.deleteTemplate(param['piPerformanceReturnsForm:template'])}

Thank you for your reply.
Could I pass the value that is entered in some other field as a "parameter" though?
<f:param name="anyName" value="parameter" />
For example the value from the following comboBox?
<rich:comboBox id="template" width="250" value="#{qtBeanParam.templateName}" enableManualInput="true"
 converter="#{templateConverter}" valueChangeListener="#{qtBeanParam.changeTemplate}" >
 <a4j:support event="onselect" reRender="template,templateList" ajaxSingle="true" />
 <a4j:support event="onchange" reRender="template,templateList" ajaxSingle="true" />
 <f:selectItems id="templateList" value="#{qtBeanParam.templateList}" />
 </rich:comboBox>

Passing multiple parameters to a portlet

Hi All,
I have created a portlet form a taskflow, and using the WSRP Producer connection I am adding this portlet into a new application's JSF page.
1. Is it possible to create a portlet that can accept multiple parameters?
2. is it possible to map a portlet method to a method in new app.
3. is there some implicit event that can be passed when all of the parameters are passed to the portlet.
What my requirement is:- I have to send some 4-5(String) parameters from the new application to the portlet application.
what would be the sequence in which the setters of this parameters would be called in the Portlet app?
can you please tell me if this is possible, and how to do it. Some tutorial would help.
Regards,
ND

Your question is WebCenter related and you should ask it in the forum {forum:id=354}.
Anyway, you can pass multiple parameters to a portlet. Define the parameters as parameters of the corresponding bounded TaskFlow. When the taskflow is wrapped as a portlet producer by the JSF Portlet Bridge all the taskflow parameters will be exposed as separate navigational portlet parameters. If you consume the portlet at some page, then the portlet parameters will be bound to PageDef variables and you can use these variables to pass parameter values to the portlet. If you have to re-send new parameter values at runtime, just set the corresponding pageDef variables and refresh the <adfp:portlet> tag by PPR. Do not forget to mark the portlet's region binding in the PageDef as RefreshIfNeeded, otherwise it will not get the new values and will not refresh.
Look at the following article in the documentation about using navigational parameter for contextually linking of portlets:
http://download.oracle.com/docs/cd/E14571_01/webcenter.1111/e10148/jpsdg_pages.htm#CHDJABHD
If you have additional questions, please ask them in the WebCenter forums.

Error while passing parameter in Oracle Jdeveloper

Hi All,
I was passed Crystal report viewer object From Servlet it is Running fine but one problem in that while passing parameter from that page to data base it is not supporting (The ok Button on page).
can any one tell me how to find Action Button (.Jsp page)
Because i am using .jsp page That was made in CR4E
in that i found only jsp code I have not get how to work Action of that button
Also another problem while making Viewer.jsp pge ..rpt-Crystal reports--->>Create Viewer Jsp->>Insert CrysatlReport viewer API code------->>>1.Connectparameterinthat report 2.connect the crystalreportPageViewer while makin this page i was running on Apache tomcat Server it is not displaying Anything only Displaying Blank Browser
Can Any one help me...
Sincerly
Amol

For your first question can you please be a little more clear as to what you are referring to? I am not familiar with an action button for the parameter pages.... what I can tell you is that we don't have any jsp code for the viewer controls, all of that is generated dynamically at runtime. We do have a viewer SDK that you can use to set properties on the viewer; information about this can be found in the [Developer Library|https://boc.sdn.sap.com/developer/library] in the Viewer SDK documentation book.
For your second question, I assume you are referring to generating a viewer page from a report in Crystal Reports for Eclipse. You will need to uncomment the viewer code (for some reason when the page is generated, the viewer code has block comments surrounding it). You will probably want to make sure the parameter code is uncommented as well.
In addition to this, there is a helper file called JRCHelperSample.java that contains all of the helper methods for the automatically generated viewer page. This can be modified in whatever way you wish to suit your needs.

HELP! Exception when Programmatically Adding a Portlet to a Page

We have been able to programmatically add WSRP Producers and Portlets into the BEA's local registry with WebLogic Portal 8.1 SP3. When we try to programmatically add a portlet to a page from within a JSP portlet we are hitting an issue. We are getting an exception when we try to call the addPlaceable method on the page instance manager. Here's the code snippet I'm using to programmatically add a portlet to a page:
IPageInstanceManager ipiManager = new PortalCustomizationManagerImpl();
CustomizationContext customizationContext = new CustomizationContext(ProxyPortletManager.LocaleHelper.findLocale("en"));
DesktopDefinitionId desktopDefinitionId = new DesktopDefinitionId("portal", new PortalPath("rdec"), new DesktopPath("enterprisePortal"));
PageInstanceId pageInstanceId = new PageInstanceId(6001);
PortletDefinitionId portletDefinitionId = new PortletDefinitionId(6002);
PlaceholderDefinitionId placeholderDefinitionId = new PlaceholderDefinitionId(2001);
PlaceableInstance placeableInstance = ipiManager.addPlaceable(customizationContext, desktopDefinitionId, pageInstanceId, portletDefinitionId, placeholderDefinitionId, 0);However, I get the following stack trace when the last line executes (ipiManager.addPlaceable):

sorry for all the replys (but i keep finding stuff)
PortalCustomizationManger is an EJB you can't just
instantiate a new instance
IPageInstanceManager ipiManager = new
PortalCustomizationManagerImpl();
you need to look it up
String JNDI_NAME =
ApplicationHelper.getApplicationName() +
".BEA_netuix.PortalPresentationManager";
portalCustomizationManagerHome =
(PortalCustomizationManagerHome)initialContext.lookup(
JNDI_NAME);
portalCustomizationManager =
portalCustomizationManagerHome.create();No need to apologize for all the replies, they are VERY MUCH appreciated. Thank you.
I tried your suggestion (although I had to change the JNDI lookup to lookup the PortalCustomizationManager instead of the PortalPresentationManager because of a ClassCastException) and I get a NullPointerException. Here is the code I am using:
InitialContext initialContext = new InitialContext();
CustomizationContext customizationContext = new CustomizationContext(ProxyPortletManager.LocaleHelper.findLocale("en"), request);
DesktopDefinitionId desktopDefinitionId = new DesktopDefinitionId("portal", new PortalPath("rdec"), new DesktopPath("enterprisePortal"));
PageInstanceId pageInstanceId = new PageInstanceId(6001);
PortletDefinitionId portletDefinitionId = new PortletDefinitionId(6002);
PlaceholderDefinitionId placeholderDefinitionId = new PlaceholderDefinitionId(2001);
PortalCustomizationManagerHome pageDefinitionManagerHome = (PortalCustomizationManagerHome) initialContext.lookup("RDECPortal.BEA_netuix.PortalCustomizationManager");
PortalCustomizationManager pageDefinitionManager = pageDefinitionManagerHome.create();
PlaceableInstance placeableInstance = pageDefinitionManager.addPlaceable(customizationContext, desktopDefinitionId, pageInstanceId, portletDefinitionId, placeholderDefinitionId, 0);...and here is the full stack trace I get when the code is executed:

How do I pass parameter to different portlet regions from another page?

How do I pass parameter to different portlet regions from
another page?
I have a page that with two regions. Each region has a report
that uses the same information to generate its report.
Individually running the reports, I can use p_arg_names and
p_arg_values to get what I want. However, when I run the page
that has both portlets, my .show is gone and I cannot get it to
use the p_arg_names, etc. Do you have any idea how to overcome
this? Thanks for any help.

Portlet event link to pass parameter between portlets

Ok list, I followed the documentation Adding Parameters and Events to Portlets
PDK Release 2 (9.0.2 and later) and tried to make a portlet that pass parameter to another portlet using event link. I created the supposed parameter in the page and made the correct association to the receiving parameter portlet. The case is: The parameter is not caught in the receiving parameter page.
This is my event link jsp code:
<%
String sImgPath = PropertiesReader.getProperty(PropertiesReader.KEY_IMAGES_PATH);
PortletRenderRequest portletRequest = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
// The portlet definition in provider.xml includes the following:
// - Event "submit" with event parameters "funcionalidade"
String eventSubmit = EventUtils.eventName("submit");
String eventParamFuncionalidade = EventUtils.eventParameter("funcionalidade");
// Build up the list of parameters for the "submit" event
NameValuePair[] eventSubmitParams = new NameValuePair[2];
// Give the 'funcionalidade' event parameter the constant value 'chat'
eventSubmitParams[0] = new NameValuePair(eventParamFuncionalidade, "chat");
// The event name must be passed as a parameter on the URL
eventSubmitParams[1] = new NameValuePair(eventSubmit, "");
%>
<TABLE CELLPADDING="0" CELLSPACING="0" BORDER="0">
<TR><TD><a href="<%=PortletRendererUtil.constructLink(portletRequest, portletRequest.getRenderContext().getEventURL(), eventSubmitParams, true, true)%>"><IMG SRC="<%= sImgPath + "menuButChat.gif" %>" BORDER="0"></a></TD><TR>
</TRABLE>
And this is my receiving parameter jsp code:
<%
String sFuncionalidade = "";
PortletRenderRequest portletRequest = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
// Get the portlet definition - needed to get the public portlet parameters
PortletDefinition portlet = portletRequest.getPortletDefinition();
// Get the public portlet parameters
ParameterDefinition[] parameters = portlet.getInputParameters();
// Display all values for each of the public portlet parameters
for (int currParameter = 0; currParameter < parameters.length; currParameter++)
String name = parameters[currParameter].getName();
out.println(" name = " + name + " ");
// Get the parameter values
String[] values = portletRequest.getParameterValues(name);
// Display the parameter's values.
if ( values == null )
// Null array indicates no values for this parameter.
out.println(" values i null ");
else
out.println(" values nco i null ");
// Loop through each of the values and display non-null values on a separate line.
for ( int j = 0; (values != null) && (j < values.length); j++ )
sFuncionalidade = values[j];
out.println(" " + sFuncionalidade + " ");
%>
And this is my portlet definition in provider.xml:

Where do I miss ???
Any help will be appreciated.
Regards,
Leandro.

Leandro,
Few things which you might want to cross check to see if we are
on the right track :
1. Page containing Parameter receiving portlet contains a
paga parameter mapped on to its public parameter.
As per your example, parameter receiving page should have a page
parameter with name - "funcionalidade" - and portlet's corresponding
parmeter should be mapped to this page parameter. This can be
done through "Parameters" tab in the Page Properties screen.
2. Page containing Parameter passing portlet contains proper event
mapping.
As per your example, we have an event called "submit". We should
be able to see "submit" event under "MenuColaboracao" portlet.
When this event is raised, select which page should receive the event
data. As soon as a page is selected, this page's public parameters
are displayed below. Beside that we must be able to see a choice box
which displays four choices one of which would be "Event Output".
Map this output to the event parameter.
Hope it helps.

Passing parameter between two portlets which are in two diffrent pages

hi,
This is query regaring passing the parameters from one java portlets to another. Or Receiving parameter from Portlets.
The Secanrio is like :
I have two portlets shown in the two different pages. Now while running the application i want to send the all the data is entered by user in the next page.
1. How to pass the value of all the parameter in the second portlet ?
2. how to name the url of the second page in action of first page

We need to use portlet events for sending parameters across different pages.
Following documents can give you insight on this :
1. http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/PRIMER.PORTLET.PARAMETERS.EVENTS.HTML

Pass parameter jspx page to portlet

Hello guys, i have one question about portlet. Curently i have 2 application, 1 weblogic portal application and 1 portlet producer application. Both project was successfully setup. I already put 1 portlet created in the portlet producer into 1 page in the weblogic portal application. The problem is, how can i pass parameter from weblogic portal page (which i call the portlet) to the portlet. Thank you

Which type of portlet you are using jsr 168 /286 or oracle pdk or others ?
Why do you need to pass parameters from portal page to portlet ?
You can very well use taskflow to achieve the same thing in a much easier way that portlet way.
If you are using jsr 286 portlet then you have to try with WSRP Soap call to get the required parameter. but I am not sure on how to achieve the final goal.

Pass parameter FROM webcenter page TO dropped portlet

Hi All,
I have created a webcenter page
I have created a ADF remote portlet
I have regsitered the portlet as producer under webcenter page "Connection"
I dragged the portlet on webcenter (jspx) page.
now, my design requires that, i should be able to pass the paramter called "Country URL" that is available in webcenter page's backing bean TO this dropped portlet's SRC tag of IFRAME.
is it possible to pass paramter FROM webcenter page's backing bean TO SRC of IFRAME inside dropped portlet ?
If yes, the how will src refer to webcenter backing URL parameter ? ( like binding ...............)

The idea stays the same in WebCenter. The technique i have described above does not change when you use ADF portlets.
There are only a few steps required:
1) Create the parameter in portlet.xml
2) assign the parameter to your portlet (also in portlet.xml)
3) deploy portlet
4) create a page parameter in webcenter on the page you are dropping the portlet on
5) assign the page parameter to the value of the portlet parameter
That's it.
Notice that the link in the above post of me (from 2010) is about JSR 168 portlets. Since WebCenter PS3, webcenter supports JSR 286 and some things change like you do not need to create the parameter in the oracle-portlet.xml anymore. You can easily do this in the portlet.xml
