Pass request parameter to portlet in jsp

Hi,
I wrote a simple PDK portlet that passes a request parameter to itself. Integrated in a portal page, the parameter passing works as intended.
Integrated in a jsp using the Oracle taglib, the parameter passing does not work. Here is the code I am using:
<portal:usePortal />
<html>
<head>
<title>Test-JSP</title>
</head>
<portal:showPortlet name="myPortlet" header="false"/>
</body>
</html>
(index.jsp)
<?xml version = '1.0' encoding = 'UTF-8'?>
<?providerDefinition version="3.1"?>
<provider class="oracle.portal.provider.v2.DefaultProviderDefinition">

<passAllUrlParams>false</passAllUrlParams>
<preferenceStore class="oracle.portal.provider.v2.preference.FilePreferenceStore">

<useHashing>true</useHashing>
</preferenceStore>

What did I do wrong?

I forgot to mention that the jsp is external and that I am using Portal 10.1.2.
With internal jsps the parameter passing works fine.
Amazingly portletRenderRequest.getRenderContext().getPageURL() contains the request parameter. It would be possible to extract it from the url. But I really don't want to do that.

How to pass request parameter to bounded task flow?

Hi, this is probably a simple question, but just not sure how this should be done. I have a .jspx that contains an ADF region for a bounded task flow. The task flow has a required input parameter, e.g. objectId. I want to be able to pass a request parameter that's sent into the .jspx page to the task flow. For example, Test.jspx?id=123 should pass 123 for the objectId input parameter of the task flow.
When adding the ADF region to the page, the Edit Task Flow Binding dialog prompted for a value for the objectId input parameter. I wasn't sure what I can put for the value so I just hard-coded something like 123 for now. So in the page definition file, sometihng like the following got added:
    <taskFlow id="testtaskflow1"
              taskFlowId="/WEB-INF/taskflow/test/test-task-flow.xml#test-task-flow"
              activation="deferred"
              xmlns="http://xmlns.oracle.com/adf/controller/binding">
      <parameters>
        <parameter id="objectId" value="123"/>
      </parameters>
    </taskFlow>I'm wondering is there some EL expression I can use for the parameter value that gets the value of the id request parameter passed into the .jspx? Thanks.

you have to use it like.. #{bean.idValue} and in the getter of the id Value use it like
private int idValue;
//setter
//getter
public int getIdValue(){
          HttpServletRequest request =
            (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
        int id = request.getParameter("id");
       return id;
}

Pass Url Parameter To Portlet in a Tab Page

Ciao,
i have a portal page with TABS. I have pl/sql portlets that read the url, then they pass parameters to the url. With "wwpro_api_parameters.get_value" and the session i am able to pass parameters via URL and to know if i have changed tab or not.
My question is: how cai i "CLEAN" the url if i change the tab? As you know, if i change tab, only the "_pageid" parameter change, and not the whole url.
i.e.: http://misun13:7777/servlet/page?_pageid=202,204,217&_dad=portal30&_schema=PORTAL30&par_name=5
I change the tab: http://misun13:7777/servlet/page?_pageid=202,206,217&_dad=portal30&_schema=PORTAL30&par_name=5
But i want to RESET the parameters! That is i want: http://misun13:7777/servlet/page?_pageid=202,206,217&_dad=portal30&_schema=PORTAL30
It seems i can't change the standard behaviour of the TAB.
Does anybody know how to do that?
Thanks in advance,
Ettore

Hi Ettore,
It is true that when you pass parameters, they show up on the URL and even when you change tabs the messy long URL will show up.
One way to avoid this, is to use the session store instead and save and access the parameter values from the session storage itself.
For more details on using Session Storage, check the PDK documentation for using the session store.
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/implementing.session.storage.html
Another thing, you may try is using the owa_utl.redirect to specifically redirect to a clean URL. But i suspect that if your parameter values are still active, they will populate the URL in any case.
For further details on parameter passing, check:
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/guidelines.parameter.passing.html
Hope this helps.

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(" <p>name = " + name + "</p> ");
// 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(" <p>values i null</p> ");
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(" <p>" + sFuncionalidade + "</p> ");
%>
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.

How do I pass a parameter to a portlet on the URL?

I have a portlet on one tab that searches for parts. (This portlet is written and maintained by someone else.) When a user clicks on a part number in the result set on this portlet they need to be taken to another tab (different portlet on the same page) with that part number as a parameter. The second portlet then dynamically writes an
<iframe src="http://someurl?partnumber=xyz" />
to call an external application passing the part number as a URL parameter to the external application.
Writing the <iframe /> dynamically is no problem. The problem is passing the part number from one portlet to another. We planned to do this by using hrefs in the part search portal using URLs like
http://hostname:port/pls/portal/url/page/test1/portlet2?partnumber=xyz
for each part number. The problem is that the URL parameter doesn't get passed to the second portlet. Here is the code in the second portlet:
<%
PortletRenderRequest portletRenderRequest =
(PortletRenderRequest)request.getAttribute("oracle.portal.PortletRenderRequest");
String partnumber = portletRenderRequest.getQualifiedParameter("partnumber");
%>
It always sees null for the partnumber parameter.
I also have <passAllUrlParams>true</passAllUrlParams> in provider.xml.
I've tried checking this by calling the URL of the second portlet directly from a browser. The portlet sees the partnumber parameter as null, but the URL window in the browser returns the modified URL from the portal with the partnumber parameter set properly. Portal is seeing the parameter but not passing it to the portlet.
I haven't tried actually setting the in the first portlet and seeing if it all works when called from inside the portal, but I don't see why it shouldn't work by calling the second portlet URL directly with a parameter.
Am I missing some step in order to pass a parameter from one portlet to another? The parameters I have to pass are dynamic, based on the result set returned by a search in the first portlet.

My second to last paragraph should have been:
"I haven't tried actually setting the hrefs in the first portlet and seeing if it all works when called from inside the portal, but I don't see why it shouldn't work by calling the second portlet URL directly with a parameter."

Can't pass bean or request attribute from servlet to JSP

Hi,
I have a web app that starts with a file upload page that uses commons io fileUpload, passes the info on to a servlet. Then the servlet passes its info on to a JSP.
I can upload the file onto the web app successfully. I also can call that uploaded file directly from the JSP (i.e. bypassing the servlet) without problem. But if I try to chain all 3 together while passing the url for the file directly as an attribute or as a bean containing file's url, I get premature end of file or can't find the property in the bean. I'm not sure what I'm doing wrong.
the error message:

Unable to pass the parameter to other portlet

Hi,
I am trying to pass the parameter from one portlet to other portlet using the convention below...
Example say you have two reports on a page dept and employee. You want to refresh employee report by clicking on
the dept in the department report in the same page.
(1) Create the first report based on the query
SELECT htf.anchor('http://domain/servlet/page?&_pageid=97&_dad=portal_dad&_schema=portal_schema&_mode=3&dept_code='||DEPTNO,DEPTNO) Department,
dname FROM scott.dept;
(2) Create a 2nd report
select * from EMP where DEPTNO = :dept_code
(3) In the the additional pl/sql code section before display page on the 2nd report do this
portal30.wwv_name_value.replace_value(
l_arg_names, l_arg_values,
p_reference_path||'.dept_code',portal30.wwv_standard_util.string_to_table2(nvl(get_value('dept_code'),10)));
(4) Created a page and added these reports as portlets.
In point (4) I am not getting the value of selected deptno in 'dept_code'. It is always taking the default value as '10'...
I like to have the quick solution for this so that I can show the demo to my client...
Thanks in Advance

Hi Ali,
We can add parameterized queries to any TableAdapter (and controls to accept parameter values and execute the query) using the
Search Criteria Builder Dialog Box.
For detail information, please refer to the following article to create a Windows Form to Search Data:
http://technet.microsoft.com/en-us/library/hbsty6z7.aspx
In addition, this issue is more related to Windows Form. I would suggest open a new thread in Windows Form forum if you have any more qestions:

Pass page parameter to discoverer portlet

Hi All,
iAS Version 10g(9.0.4)
I created worksheet(graph) using Discoverer plus having 4 parameters. I published the
discoverer graphs as discoverer portlet in Oracle portal. However for this worksheet it shows
(No parameters) in Page --> Properties --> parameter. I created simple parameter portlet with
4 items, this entry I need to pass to this discoverer portlet/Worksheet.
Any suggestion would help.
Thanks

Hi,
Thank for your reply.
We are using discoverer plus for relational data (Oracle 10g (Ias 9.0.4)).
Appreciate your feedback.

How to pass page parameter to report portlet ?

Portal: 9.0.4
RDBMS: 9.0.1.5.0
OS: Windows
REF: How to pass page parameter to report portlet ?
Hi,
I create a Oracle Report as a Portlet in Portal (create Report Definition File Access and check on the option "Publish As Portlet" in the on the last step). My report has an "Additional User Parameter" and I has let it "Visible to user".
When I put this portlet in my Portal page, I can see this parameter in the property/parameters of this page. However I cannot transfer my page parameter to this portlet parameter. Other portlets in this page (non-Oracle-Report portlets) are working fine with my page parameter.
Please advice.

I want to make sure we are talking about the same thing:
After you add the portlet to the page, you go to the page properties, then the parameters tab, then there is a section at the bottom called "Portlet Parameter Values" where you can click and expand your portlet to see your portlet parameters.
Is it here where your parameters just don't show up?
If it is, try the following:
- Add the portlet to another page and see if it still behaves the same.
- Mark the parameters in the portlet as being non-public, re-generate portlet (on manage tab), then mark them as being public, re-generate and then try the above again (add to another page).

Remove danger of using a request parameter in a JSP:include

HI,
I have a basic include where the filename is controlled by a request parameter:
<%String fileName = request.getParameter("param1")+".jsp"; %>
<jsp:include page="<%=fileName%>" flush="true" />This works fine but I am rather worried about the security as some can easily edit the URL to something like this:
http://www.mysite.com/include.jsp?param1=../../../passwords
Does anyone have any good security techniques that would strip out anything in param1 that could potentially be rather dangerous?
Thanks

Check/test the request parameter before using. Best way is to use a (controller) servlet for this.

How to pass the dynamic request parameter value $fieldName:IsSelected for framework folder service FLD_PROPAGATE?

Hello All,
I created a WSDL for Framework folder service FLD_PROPAGATE and FLD_PROPAGATE service has following two required request parameter:
$fieldName:isSelected: Set to 1 to propagate the specified field.
$fieldName: The value of the field to propagate
So, I am facing issue in passing the parameter $fieldName:isSelected.
I tried to pass the request parameter as mentioned below in SOAP UI request payload but still this is not working and error message is: "Unable to propagate. Please select at least one field to propagate"
<csx:fSecurityGroup:IsSelected>1</csx:fSecurityGroup:IsSelected>
<csx:fFolderGUID>C7F5CBB4E54A790E21E18CE378B16EEB</csx:fFolderGUID>
<csx:fSecurityGroup>Public</csx:fSecurityGroup>
Could you please suggest for the correct way to pass these parameter values? If anyone have sample WSDL for this service please share?

Passing Request Attributes in betweeen pageflow Portlets

Hi
How to pass Request Attributes in between Pageflow Portlets
I tried with ScopedServletUtils class but it's not working for me
Thanks

Consider using events to pass data between portlets. Refer to docs about
Interportlet Communication (IPC).

Passing session parameter to a portlet from webcenter spaces page

How do you pass a parameter to a portlet on a WebCenter Spaces page? For example, I have the user's company ID in the session, I need to pass that company ID to the portlet defined to accept a company ID parameter so that the returned data can be filtered.

You can for example add the companyID to the url of the page and then pass that parameter to the parameter of your portlet.
Have you created your portlet to enable inter portlet communication? You should first do that and create a navigation-parameter in the oracle.xml. If you don't know what i'm talking about, i'll explain a bit more.
Their is another way, which is easier i think, is to set the value of your portlet parameter to an expression language refering to a session variabel.
In you portlet parameter set the companyId (if you have created a navigation-parameter companyID) to following value:
#{sessionScope.company}You will have to set the value of that session variable from within your webcenter spaces.
How are you doing that? Are you planning on setting that variable using another portlet, taskflow,... This can be very important on how webcenter reactt on parameters and it can also give you additional ways on passing the parameters.

Pass a parameter from one ASP portlet to another ASP portlet

We are trying to pass a parameter from one ASP portlet to one or more other ASP portlets.
We are using PDK-URL Services and have created a provider.xml for each of the ASPs and the ASPs work as normal within the portlets created.
We are now trying to use PDK-URL Services to pass parameters to a portlet. As a first step we set up a portlet which displayed an ASP, this ASP (and the portlet) expected a parameter. If the parameter value is left blank the Portlet displays a default page (not the ASP page) for passing in the parameter i.e. a text box and a submit button. If the parameter is entered and submitted the ASP page returns and the results of the query are based on the parameter typed in.
As the next step what we are now trying to do is pass a parameter from one ASP portlet to another.
The Documentation says that there are two types of parameters Qualified where Parameters will be passed only to the initiating portlet i.e., portlet which contains them and Unqualified where all portlets will be affected by the parameter sent by any portlet.
Very little information was available on this, apart from the one liner explanation of each (above).
When we tested the above, using the PDK sample ("ParamCustomizationPortlet") portlets it doesn't appear to be doing anything in particular.
Any ideas on the best approach to passing parameters from one ASP portlet to another?
Thanks for your time.

We can visualize Qualified and Unqualified parameters only when there are multiple portlet instances in a single page. For example, add two instances of ASP portlet you have created, and submit from one portlet. You can see the other portlet also receiving this parameter, provided you are using unqualified parameters.
Thanks,
Amjad.
