Problem in retrieving query string parameters

Question

Hi All,
AM working on wsrp in weblogic..Have a doubt in it..
I have two tabs in my application home page..One is tab HOME and another one is tab SEARCH..
So i want to navigate between these two tabs and i have my consumer portlet in tab HOME and producer portlet in tab SEARCH..
AM trying to pass some values when i click the tab SEARCH from the home page in query string using <render:param> tag.. AM using that tag, since have used <render:paramURL> tag for navigation..
so it will be like this:
<render:param name="test" value="sample"/></render:pageUrl>">
but am not able to retrieve the value in my producer doview()..
i get NULL value
when i try to access it using
request.getParameter("test")
but when i focus the mouse pointer on the SEARCH tab in my application, i see the value gets appended to the query string but not able to retrieve it inmy producer portlet..
Does anyone have idea about this??
Regards

Hello,
There is no way to generate a URL to another portal page from a producer portlet, as the producer has no idea what the structure of the consumer-side portal looks like or how to change a page.
By far your best bet is to use events to change the page, and put an "activatePage" handler on the portlet on your "HOME" page, and send an event to trigger the page change.
Put an "activatePage" handler in your remote portlet's .portlet file (on the producer side), such as:
<?xml version="1.0" encoding="UTF-8"?>
<portal:root xmlns:html="http://www.w3.org/1999/xhtml-netuix-modified/1.0.0" xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0" xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0 portal-support-1_0_0.xsd">
    <netuix:portlet title="Sample Page Activating Portlet" definitionLabel="eventsLinkDef1">
        <netuix:handleCustomEvent event="SampleCustomEvent">
            <netuix:activatePage /> <!-- This changes the page to the page this portlet is on when this event is received -->
        </netuix:handleCustomEvent>
        <netuix:titlebar>
            <netuix:minimize/>
            <netuix:maximize/>
        </netuix:titlebar>
        <netuix:content>
            <netuix:jspContent contentUri="whatever"/>
        </netuix:content>
    </netuix:portlet>
</portal:root>This way, when you send the event (and you can include a payload in the event if you want to send search terms), the consumer will automatically switch pages to the page containing the search portlet. And it works over WSRP and locally (not over WSRP).
