Adding a Portlet Parameter

Does anyone know how to add a paramter to a portlet?
We have developed a portlet and we would like several instances of it on a page. We need each portlet to accept a different parameter to show different results. But how to we allow the portlet to accept a parameter.
I've read something on Portal Studio about a file called provider.xml that allows you to add paramters. But I don't know if this is a generic name or if you have to create your own (and if so, where it is created).
Help would be appreciated,
Thanks,
Martin

Peter,
We are using a combination of Omniportlet and developing out own portlets using the PDK using PL/SQL
In this particular instance we have developed a portlet that dymically displays contents using, primarily, the htp.p package. It displays information for a particular day of the week. I have a page that has 7 instances of this portlet (one for each day of the week). What I'd like to do is for the portlet to call a package that passes the Day of the Week as a parameter so that it can query back the results for that particular day into the correct portlet.

Unable to bind portlet parameter with page parameter in webcenter portal

Hi All,
I am trying to bind portlet parameter with the page parameter so that I can ahieve some business requirements.
Here is what I did,
In my Portlet producer application:
1) Created standards based portlet (jsr 286) with view.jspx and edit.jspx with rest of the things being default.
2) In my portlet.xml created two parameters and assigned these parameters to the portlet created above.
3) In the view.jspx added couple of output label adf components in the page.
4) deployed this to integrated weblogic server.
In my WC portal application:
Created a new page and added the portlet to this page( WSRP connection already exists).
deployed portal application on integrated server.
In the edit mode of the page I added one page parameter(Param1) and some default (constant) value added.
What I want is this:
when Param1 value is One display first output label and
when Param1 value is Two display second output label.
I am using jdev 11.1.1.5.0 with integrated weblogic server.

There is no need to use page parameters for this.
You also have two types of parameters depending on what you want...
1) Preferences: these parameters can be used on a user based level. This means that users can personalize the portlets. When a user change the value of a preference, it is only applied for that specific user
2) Public parameters: these parameters are used to customize the portlet. The value you set in these parameter apply for all users.
I have made a simple example to show these two differences: http://www.yonaweb.be/PortletTest.zip
The portlet has 4 inputText on it. The first two can be set by specifying One or Two into the preference.
The other 2 inputText uses the value of the public parameter.
You should only deploy the portlet and consume it in a webcenter application. In the webcenter application, you don't need to do anything special. All is done in the portlet.
I am guessing you don't have written the code that will get the value of the parameter:
in case of a preference you will get the value by following code:
   PortletRequest request = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
   PortletPreferences preferences = request.getPreferences();
   return preferences.getValue("outputparam", "One");In case of a public parameter (for customization instead of personalization) you use following code to retreive the value of a public parameter:
PortletRequest req = (PortletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
String param = (String)req.getParameter("PublicParam");
if(param == null)
      return "Three";
return param;This code can also be found in the sample portlet application.

How to control the call to a data control using portlet parameter

hi,
i'm using a web service data control on my portlet application. I'd like to know if there's a way where in the data control will not be called when the portlet is loaded,unless the portlet parameter is specified.
thanks in advance!
Rian

thanks Yannick!
Here's what I did
1. Create a web service proxy
2. Create a java class that will manually call the web service (instantiate the service and port first?)
- Can I retrieve the portlet parameter in this class?
3. Create Data Control out of the POJO class
- Does this mean I have to code setters/getters inside Java class (for the input and output of web service) in order for me to put the fields onto my portlet?
Given your sample, am i understanding it correctly that once it's converted to a data control, you'll drag the getUserList method onto the page as parameter form?
** EDIT***
it's now working. I have a POJO that will call the service proxy and then I have a Bean that will call the POJO method. I created a Data Control out of the POJO class as well,so I can place elements in my page using drag and drop of POJO's methods/variable.
thanks a lot for your help

I am able to connetct from JRMC. After removing -Xmanagement all is working.

Can you please take a thread dump and copy paste the stack trace for the Thread called "main" thread.
Please take atleast 3 thread dumps with an interval of 10 seconds and paste the "main" thread stack trace from all the 3 thread dumps.
After analyzing the stack trace we might be able to determine where it is hanging and thus giving us a clue where the issue could be.

Perhaps you're not handling the "EndOfStreamEvent" correctly/at all, and thus not freeing up the socket to listen for the "NewReceiveStreamEvent " after the initial stream has ended...

Reports Portlet Parameter Form LOV Format

Hi,
I have created several LOV's that I want to use in the Reports Portlet Parameter Form for running Oracle Reports, but the format I am choosing when creating the LOV's is not showing correctly on the parameter form. I am picking 'Check Box' and 'Radio Group' for several of the LOV's, but they are still displaying as Dropdowns on the parameter for. Am I doing something wrong here, can the parameter form show check boxes and radio buttons?
Thanks

hello,
i am afraid the answer to both questions is 'no'. i would suggest you create some HTML/JSP parameter forms for your reports. the parameter form editor of reports is very limited and for more complex requirements we suggest using other tools (or the JSP web source of reports, which is available from 9i onwards).
thanks,

Disabling the 'Schedule' tab on the Reports Portlet Parameter Form

Hi,
I have deployed several Oracle Reports through Portal using the built in Reports Portlet Parameter Form and I was wondering if anyone knows how to disable the 'Schedule' tab located on this form. I would like users to run the reports but not to schedule them.
Thanks

Hi .
I forgot to say that, the reports is an XML report .

Hi.
I am facing a problem with the parameter form in reports 10g. The number of parameters in this report are huge. After designing the parameter form , i save and close the report. Now if i re-open the report to do changes, the width and height of the parameter form is reduced (which i increased changed previously) and if i click on any field , that specific field is repositioning itself inside the (reduced)border lines.
I request the forum to give a remedy on this issue.
thanks in advance

Multiple portlet instances with public portlet parameter.

If I have a java Portlet with a public portlet parameter, and I put two portlet instance (same portlet) on the same page.
Can page designer assign different value for the public portlet parameter of different portlet instance?
Or the question is:
Is public portlet parameter per portlet definition, or per portlet instance?

Hi Derek,
Let me give it shot. Gurus correct me if I am wrong!!
In an hosted environment we can have multiple Organizations or Organization units that may be catered with a single Oracle9iAS Portal instance. In which case each of these Organizations / Organization units will be Subscribers to the Oracle9iAS Portal and will have an unique Subscriber ID. A company name is a part of the Subscriber profile so a subscriber has a Company that it belongs to. So if the Marketing dept. of a 'X' company is a subscriber to Oracle9iAS Portal, then this Subscriber will have a Subscriber ID associated to it and the Company that he belongs to is 'X'. So we can have a Company who has one or more subscribers to Oracle9iAS Portal.
The distinguished name, or DN, is the identifier for unambiguously referring to a particular entry in the directory. The DN is formed by sequentially connecting all
the individual names of the parent entries of the node, back to the root.
I hope this helps, please get back in case you have any questions.
Take care,
Manoj

Create customised page for adding removing portlets

Hi All,
I want to make a customised page which has checkboxes preceeding the portlet name which the user can use for adding/removing portlets . This requirement is similar to the add/remove portlet page provided on my.oracle.com when we go for customization of our page. I would like to know how to go about it and if any reference code exists for the same.
thanks

The problem - IF we were the only company using the product - AND this were only an internal portal. That might be acceptable.
The problem with that is that we are using portal in a way that was not considered by the developers.
We are using portal to customize (not per department) - but per CLIENT or CUSTOMER. That means - when we implement a site for one of OUR customers. We are not going to be customizing in house per customer. We will be allowing the CUSTOMER to customize their own site (AND their portlets).
Now - a customer from "ABC Company" does NOT want to customize something and see a whole bunch of generic stuff. They want to see THEIR stuff in "ABC Company" format with their logo etc. Any other way is unacceptable.
This use case needs to be revisited by the Oracle development team to address this issue if the only option is that we can't customize the page. (I assume that by hunting through the JDK, and looking through code - I might have a chance... but I was hoping for an easier solution).

Adding a new parameter to the existing report in GL(GLRTR1.rdf)

Hi Friends,
I was new to this oracle Forums and i am working as a oracle apps technical consultant, i have been assigned a task in GL module to customise the existing report in GL the report name is "GLRTR1.rdf" (available in vision-demo) and its concurrent program name is "Trial Balance Summary-1" this program has the predefined parameters like:
(Parameter Name : Values to be entered/as u wish)
Pagebreak Segment : Company
Pagebreak Segment Low :01
Pagebreak Segment High:01
Currency :USD
Period Name :feb-2003
Amount Type :PTD(Period to Date)
user-parameters to be added to above parameterlist
costcenterfrom :segment2 value of (GL_CODE_COMBINATIONS table)
costcenterto : -- do---
Now what i want is i want to add a user parameter to this concurrent program like costcenterfrom and costcenterto these are optional parameters and the its value set type is TABLE and i want to display value is SEGMENT2.
when i select the parameters along with predefined and costcenterfrom and costcenter to the report output should be between the costcenter from and costcenterto along with predefined values,
and if i am not giving any value to the costcenterfrom and costcenterto parameters then the report out put should be based on the above parameters ie predefined parameters only.
i think u haveunderstoood the requirement and does any one please tell me know the solution for my problem its very urgent.
i will be very greatful to them.

Hi,
Please check whether the auth object is switched on for the info-provider or not. By default its switched on if the info-object is part of the info-provider.
To switch it on again, enter the info-provider name in the section 'Checks For Info-provider'. Click on pencil button to enter into change mode and select your auth object.
Hope it helps

How to make url portlet parameter permanent

I have set up a url portlet inside portal.
I put tags in the provider.xml file for an input parameter for my url portlet to use. (I used the <isMandatory>true</isMandatory> so I would be prompted inside portal for the value.)
So, when I add the url portlet to a portal page a window pops up and asks me to submit a value for the portlet to use.
The portlet runs sucessfully.
MY QUESTION: How can I make the value that the page creator enters permanent so that the url portlet automatically picks it up whenever the page is run?
My purpose is to be able to add this portlet to several different pages and have it use the value that was defined for it when the page was created.
I have read several articles, but I must be missing something. Any ideas are appreciated.

Hi,
You can make the following change in your provider.xml file.
<inputParameter class="oracle.portal.provider.v2.URLPortletParameter">
<name>csz</name>
<isMandatory>false</isMandatory>
<value>Set your value here</value>
<displayName>What location do you want a map for (City, State or Zip)?</displayName>
</inputParameter>
By doing so, it'll pick up the value from the provider.xml and append the value to the parameter in the URL, so that the constructed URL will have the parameter value without having to customize the page.
I hope this answers your question. Do feel free to come back here if you have any more problems.

System.MissingMethodException after adding an optional parameter

I am getting error of System.MissingMethodException after I have an optional parameter in one component and the other component which call it was not build as it call it with old number of parameters.
Only component in which parameter is added was build an deployed as patch. The calling component is old as there is no change in it.
When the calling component run it gives error :
Exception Information
Exception Type: System.MissingMethodException Message: Method not found: 'LabelURLs IPSD.BnB.Transaction.Postage.GetLabelURLs(System.String)'. Data: System.Collections.ListDictionaryInternal TargetSite: Void GenerateScanForm(Int32, Int32) HelpLink: NULL Source:
BnBDispenseQueueProcess
As far as i know it should not raise an error as new parameter is optional. One more thing calling component(EXE) run as windows service.
we found an very wired workaround to make it run. By Removing the changed component once and run calling component which will say DLL not found. The place the same DLL again and calling component works fine:).
I think i am missing some internals of .net.
Let me know if more info needed.

Adding a portlet to a page like the customize or edit link

I hope somebody else out there has seen or tried this...
I would like to have a list of portlets, similar to the way the repository displays them, inside of a portlet on a page. Each entry would be a link, that when clicked, would add the selected portlet to a different region on the page. Basically it would be a way to do the customize (add/remove portlets) function without having to click customize and drill into the repository. Is there anything in the PDK APIs or something that can do this?
Thanks,
Mike

Hi Mike -
What version are you using? The Portlet Repository Page group in 9.0.2.6+ is what you see when you add portlets through the normal UI. You can have a look in there and see what they call.
Hope this helps,
Candace
