want to send data from portlet

[davinchi]

How can I send data catched from a portlet,
Suppose I have a jsp, on submitting the request I want to send the data on the page to another portlet.
I know that I can process using processAction and render methods but I dont know how I can call them from a jsp.

Hi,

Use RequestDispatcher (RD) and request.setAttribute().

public void doView (RenderRequest request, RenderResponse response)
 throws PortletException, IOException
{
 response.setContentType("text/html");
 request.setAttribute("myAttr", "myValue");
 PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher("another.jsp");
 rd.include(request,response);
}

The point is to set up the content type of a response (very likely it's text/html) *and* use RD.include() as forward() is not allowed.

BTW, You may find this and other answers in a very valuable book - http://www.manning.com/books/hepper. It's distributed at no charge (!)

thanks jacek,

But additionally if I on click of submit suppose I want to invoke a portlet.
I tried using the following command

PortletURL cancelUrl = aResponse.createRenderURL();
cancelUrl.setPortletMode(PortletMode.VIEW);

but these methods are not present in my jar.(I think they are specific to pluto)

How can I do the same in JBoss Portal

Hi,

You didn't read the book, did you? ;) Neither did I yet, but I'm pretty sure there's the answer. Anyway...

As you might've tried, you can include a jsp page into a portlet. So can you include a servlet, since a jsp is a servlet at runtime. Create a servlet-mapping (if it's not done for you automatically, e.g. /servlet/YourServlet) and include it into PortletRD as you did with the jsp.
