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 to page fragment in dynamic region

Hello.
I am using Jdeveloper 11.1.1.3.
Can anyone explain to me how to pass parameter to page fragment in dynamic region?
My situation is:
I have only 1 page: index.jspx.
This page include 2 elements:
1. <af:tree>
<af:tree id="t1" var="node" rowSelection="single"
value="#{bindings.FpsrVO1.treeModel}" rendered="true" expandAllEnabled="true"
contentDelivery="lazy" initiallyExpanded="false"
contextMenuSelect="false" fetchSize="-1">
<f:facet name="nodeStamp">
<af:commandLink id="cl1" rendered="true"
actionListener="#{backingBeanScope.RegionDynamicBean.treeClick}">
<af:outputFormatted id="outForm" value="#{node.Name}" rendered="true"/>
<f:attribute name="menuId" value="#{node.Code}"/>
</af:commandLink>
</f:facet>
</af:tree>2. <af:region> :
<af:region value="#{bindings.dynamicRegion1.regionModel}"
id="r1"/>Region could be changed to 3 bounded taskFows wich have only one page fragment.
Can anyone explain to me how i can send <f:attribute name="menuId" value="#{node.Code}"/> from tree element to page fragment which will be rendered on screen?

You can pass a map to the dynamic region which would take the task flow parameters as key-value pairs.
<taskFlow id="dynamicRegion1"
taskFlowId="${backingBeanScope.TestPageBean.dynamicTaskFlowId}"
activation="deferred"
xmlns="http://xmlns.oracle.com/adf/controller/binding"
parametersMap="#{backingBeanScope.TestPageBean.parameters}"/>
When reloading the taskflow, ensure that the necessary parameters are loaded into the taskflow.
Check this example exactly based on your use-case:

Pass parameter from page link to report

How can I pass 3 parameter values from a link on one page to a report or CrystalReportViewer. Report is a CR/VS 2005 web report in C# Parameter fields in the report are: CampaignID BeginDate EndDate So say link page URL looks like this: <a href="http://localhost/reports/campaign_report/default.aspx?CampaignID=61325&BeginDate=1/1/2006&EndDate=1/2/2006" target="_blank" title="http://localhost/reports/campaign_report/default.aspx?CampaignID=61325&BeginDate=1/1/2006&EndDate=1/2/2006">http://localhost/reports/campaign_report/default.aspx?CampaignID=61325&BeginDate=1/1/2006&EndDate=1/2/2006</a> and I want to pass these values to the report and bypass the Parameter Prompt Page.When i run this link the report viewer page says "missing parameters"Do I need to add something to the default.aspx.cs page? -- protected void Page_Load(object sender, EventArgs e) { Parameter.Field1 = (CampaignID); Parameter.Value1 = Request.QueryString("CampaignID"); ...?? } --
 Any help would be greatly appreciated? Thank you, Jason 

Â Hi Jason
Â You are correct.Â The Viewer object will not automatically look at the URL and try to assign the values.Â You need to grab these values from the URL and properly assign them to the parameter objects.

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

URGENT:How to pass parameter to page from java portlet

Hi,
All i need to do is to pass a parameter from my custom java portlet to an omniportlet. Is it achievable? If so, please point me direction!
Thanks,

Hmm yeah or else you could use java.net.URLEncoder.encode(String s) to encode it automatically.
(java.net.URLDecoder.decode(String s) decodes btw)

how to pass List parameter?

Hi
You should pass your parameter with the <f:attribute> tag.
See this sample:
<af:declarativeComponent id="dcPrj" viewId="/WEB-INF/views/template/project.jsff">
<f:attribute name="dataMap" value="#{backingBeanScope.vlbb.projectData}" />
</af:declarativeComponent>
Where my "projectData" is a HashMap and declared in the fragment as it.
<af:xmlContent>
<component xmlns="http://xmlns.oracle.com/adf/faces/rich/component">
 <display-name>ProjectTemplate</display-name>
 <description>This component will show project info.</description>
 <attribute>
 <attribute-name>dataMap</attribute-name>
 <description>Map with all data required</description>
 <attribute-class>java.util.HashMap</attribute-class>
 <required>true</required>
 </attribute>
</component>
</af:xmlContent>
I hope this solve your problem.

Passing parameter between pages

Hi all,
I have a project which has two pages, and those pages act like master-detail. The master-like page is a read-only form with navigation buttons. The user navigates the records and when the user finds the record, s/he clicks the submit button, which opens a dialog window with an editable form displaying the record.
I wonder how I can set cursor on the record and display it on the opening page.
Thanks in advance.

Hi,
when you open a separate dialog then - in ADF Faces you use the dialog framework. Ypu can use the launch listener on the button that you use to launch the dialog to pass information to the dialog

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.

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 ...............)
yhx
dd

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
This is a more up to date post: http://yonaweb.be/inter_portlet_communication_jsr_286_and_webcenter_11g_ps3

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.

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.

Help - Passing parameter to report using page parameter

I have a SQL Report on a page
The report query is
select * from scott.emp where deptno = :department
The URL for the page containing the report is:
http://developer03.fis:7777/portal/page?_pageid=95,36455&_dad=portal&_schema=PORTAL
I have added a page parameter = departnment
and associated the page parameter to the report bind variable in the Portlet Parameter Values as follows:
department = Page Parameter, department
I displayed the page by going to the above URL
and then added &department=10 to the end of the URL in the browser address.
I expected the report to display records for deptno = 10, but the query didn't return any records.
Anyone know what's wrong??
Thanks Larry

Yes, except you need to add &department=10 to the end of the page URL, not what I had.

Need Help with CommandLink Passing rowKeyStr to 2nd JSPX Page

I've been working about 8 hours on something that should be simple - I have a databable displaying rows of data with a simple command link on one of the columns that will send the user to a 2nd page with a single record form showing detailed information for the selected row.
The problems I'm having:
* When I press the commandlink I do not get the correct record on the 2nd page
* Also I'm receiving the following error: JBO-25020: View row of key oracle.jbo.Key[11 ] not found in SearchViewIterator
When I use the af:tableselectone (selection) button to select the row first and then click the commandlink, the 2nd page DOES display the correct row, however I still receive the 25020 error above.
Note I am using the same View Object and Iterator for both pages.
I have compared my code against the SRDemo application and cannot see any differences - I was hoping someone could review my steps to see if I'm missing something (using JSF and ADF BC 10.1.3):
Page 1 JSPX Code Snippet (commandLink / ActionListener):
<af:commandLink actionListener="#{bindings.setCurrentRowWithKey.execute}"
action="viewisp"
text="setCurrentRowWithKey"
disabled="#{!bindings.setCurrentRowWithKey.enabled}">
<af:setActionListener from="#{row.rowKeyStr}"
to="#{processScope.rowKeyStr}"/>
</af:commandLink>
Page 1 JSPX Page Definition File Snippet:
<action id="setCurrentRowWithKey" IterBinding="SearchViewIterator"
InstanceName="SearchDataControl.SearchView"
DataControl="SearchDataControl" RequiresUpdateModel="false"
Action="96">
<NamedData NDName="rowKey" NDValue="#{row.rowKeyStr}"
NDType="java.lang.String"/>
</action>
JSPX Page 2 (destination - single form) - Page Definition Snippet:
<executables>
<iterator id="SearchViewIterator" RangeSize="10" Binds="SearchView"
DataControl="SearchDataControl"/>
<invokeAction id="setCurrentRowWithKeyStr" Binds="setCurrentRowWithKey"
RefreshCondition="#{adfFacesContext.postback==false}"/>
</executables>
<action id="setCurrentRowWithKey" IterBinding="SearchViewIterator"
InstanceName="SearchDataControl.SearchView"
DataControl="SearchDataControl" RequiresUpdateModel="false"
Action="96">
<NamedData NDName="rowKey" NDValue="#{processScope.rowKeyStr}"
NDType="java.lang.String"/>
</action>
Finally - I did see some other posts related to the JBO-25020 error. The recommended Solution was to add the following code to the underlying ViewObjectImpl class:
protected void create()
{ setManageRowsByKey(true);
super.create(); }
This had no affect.
thanks for any help.....
ps what exactly is stored in the row.rowKeyStr? is it based on data columns in the row?

Finally got this to work - thought I would post the solution that worked for me here in case anyone else runs into this:
Note: Page#1 = Search Form - ADF parameter form and ADF read-only table (uses CommandLink to pass record to page#2)
Page#2 = ADF read-only form - uses same VO and same iterator as page 1
1. As Frank in his reply above, I don't need to use an ActionListener, but only use the commandlink for navigation. I did need also to set the current row when the user clicks the command link as described in the JDev help (Adding Tables | Setting the Current Object Using a Command Component) - this was a step I was missing before.
2. NOW, here is where it gets Interesting - to avoid the issues of:
a. page#2 not displaying the correct record selected, or, inconsistently displaying the correct record; and/or,
b. receiving a "JBO-25020: View row of key oracle.jbo.Key[num] not found in xxIterator"
I had to EITHER:
A. Set the SyncMode for the DataControl in databindings.cpx = Batch (as described in http://www.oracle.com/technology/products/jdev/tips/muench/batchmode/index.html)
OR,
B. Keep the SyncMode for the DataControl as Immediate, BUT override the following method in ViewObjImpl as described in some previous forum threads related to JBO-25020 error:
protected void create()
{ setManageRowsByKey(true);
super.create(); }
This is what I found (after much trial & error) worked for me - I'm curious to see if others have come to the same conclusions.
thanks

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 + " ");
%>

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.
