Parameter confusion in portlets

Hi
I was developed two Java portlets in JDeveloper 9.0.2, using JSP and BC4J.
Both portlets displays data in a browse form (Next, Prevous link).
These two portlets are displayed in the same portal page (Portal 9.0.2).
Scenario:
When I click the Next link, built by the DataScroller component, on the first portlet, the next record set isn't displayed in the first portlet (perhaps here is another problem), after the page was reloaded, but in the second portlet raises an error, which tells, that the view object doesn't exists (this view object is referenced only in first portlet).
I think the second portlet receives the first portlet parameters (jboEvent, jboEventVo).
how can avoid this??
thanks.

Hi, thanks
exactly, that what get me confused, here is the link in the official documentation: http://docs.oracle.com/cd/B19306_01/server.102/b14239/create_ps.htm#i68626 please look at the
Example 3-4 Primary Database: Standby Role Initialization Parameters paragraph, and here is another link witch says a different thing, please search for string:
alter system set db_file_name_convert='/oracle/oradata/standby','/oracle/oradata/primary' scope=spfile sid='*';
What are you confused about.
That doc shows you a COMPLETE example of the parameters, and their order, for both the primary and standby databases. See Example 3-5 for the standby settings.
You should do yours the same way and in the same order.

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:

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."

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.

A sample question about parameter passing between portlets

How can I pass parameter between portlets in one page using pdk API. Please give a demo. Thx

In one portlet I send parameter using form: actionn="<%= UrlUtils.htmlFormActionLink(prr, UrlUtils.PAGE_LINK) %>"
<input type="text" size="20" name="textname" value="">...
Then I want to receive the parameter in another portlet. My code is:PortletRenderRequest prr = (PortletRenderRequest)
request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
out.println( prr.getParameter("textname") );
But why I can't receive the parameter successfully.
Thanks for any help!!!

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).

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.

Parameter Pass Between Portlets

Hi,
I'm trying to get a parameter pass between two portlets on the same page, I've looked at the PDK samples but have not been able to get either working, I'm on 9iAS R2 (9.0.2.0.1.). I've installed the PDK and loaded up the various samples. Any information or guidance appreciated. In a nut shell I'd ideally like to pass a parameter from a report (java or pl/sql) in one portlet to a portlet next to it on the same page which can then run a second report (java or pl/sql).
Regards
Stephen

Hi Peter,
We have an omniportlet that displays a graph, we want the user to be able to pick a value from this graph and pass it as a parameter to another page containing another omniportlet which would select values based on the parameter value.
We have 9ias version 9.0.2.6.2. Your help will be greatly appreciated.
thanks,

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.

Accessing the Query String parameter from a portlet

Hi!
I have developed a PDK portlet in Jdev 10.1.3.3 for Web Center (Just for testing, later it'll go on Oracle Portal 10.1.4). I am trying to access the query string parameter coming in the URL but not successfull at all. Following are the options that I have tried in vain :
In MyPDkPortletShowPage.jsp with *<passAllUrlParams>true</passAllUrlParams>*
1.) PortletRenderRequest pReq = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
pReq.getParameter("data");
2.) request.getParameter("data");
3.) request.getAttribute("data")
This makes me ask that is there any other way to access the parameter or is it simply not possible?
Please suggest!
Regards,
Neeraj.

Hi Neeraj:
I didn't deal with web center before i am working on Oracle Portal 10.1.4 so if you done that on oracle portal and got the same problem check for this?
- add the parameter in the page parameter then you will get the value from either preq.getParameter or from request.getParameter,just go to page properties and add a page
parameter called data
- did you publish your page containing your portlet as portlet and included it in other page or it is just a page containing this portlet?

Rule for parameter values when portlet defined?

Am I missing something?
In Plus:
--I make a sheet in Plus that is parameterized.
--The parameter for an item whose item class has a LOV.
--I define a default value.
--I save the sheet.
In the portal:
--I define a Disco portlet.
--I edit the defaults.
--I set the parameters.
Now, here's the weird thing: The only parameter value offered is the one saved as a default value in Plus?
This certainly makes no sense at all.
This is on 9.0.2.53.12
Anyone?

CheckBandwidth()'s result parameter confusion

Hi everybody,
Please help me on a confusion, which is:
1) I am calling the checkBandwidth() method of FMS for a client.
2) It calls back the onBWDone method client side with four parameters, first parameter as bandwidth, second and third not used and fourth as latency
My request is that the Bandwidth value recieved is what kind of bandwidth:
Is it the total bandwidth available to the client and includes upBW as well as downBW
or
is it just the Down bandwidth available of the client
Regards,
Sahil.

Hi TanujM,
Thanks a lot for replying, that solves one of the problems i am facing!!!
I studied the link you have given as well as other links.
I wish to publish videos based on user/client bandwidth. So I am working on an assumption that there is an UP bandwidth and there is a DOWN bandwidth ie ClientToServer and ServerToClient bandwidth respectively.
Now the bandwidth that i get using checkBandwidth() is total of both up and down.
So my next request is that:
Is this assumption correct, that there are different up and different down bandwidths between user and FMS.
I see it as having a total BW-pipe that contains two smaller pipes UpBW-pipe and DownBW-pipe and both are independent of each other. I feel I am wrong on this assumption.
Does consuming one pipe effects the other?
Thanks and Regards,
Sahil

Can not pass Number type parameter to a portlet.

I created a portal applicaiton with a jspx page.
when click on a row of the table , a portlet will get the id of the row, and portlet will be refreshed.
The id type is Number.
when running, logs contains a error:
"PortletModelImpl> <setParameterValue> Cannot set parameter Param1 on PortletBinding OmniPortlet4_1 with a value that is not a String or String Array."
if you change the id type to String, everything will be OK.
but the id type should be number, how to solve this problem.

You should pass the value as a string to your portal and in your portlet convert it back to a number.
If you really want to pass the Number object instead of a string, you can always use events instead of just passing parameters. When you use events, you can attach a payload to the event which can be any type as long as it is serializable.
