submitting tree2 node to a serlvet
Hi,
I am using tree2 component.
I have a kind of windows explorer UI, where in my tree nodes are formed with
folders, sub-folders and files.
For the same I have three different facets like "folder", "sub-folder" and
"document" in my tree2 component.
Now what I want to have is, whenever "document" type node is clicked I have
to open that particular document in my browser window.
For that I guess I need to submit my action to the HttpServlet which reads
the file data and opens in the browser window (by putting file data in the
Servlet stream).
Can anybody tell me how can I submit the click action of any tree node to
HttpServlet?
Or is there any other way to achieve the above kind of functionality?
Thanks
Mihir Solanki

Re: submitting tree2 node to a serlvet
Posted by Rob Decker <ro...@objectsource.org>.
Have you tried using a plain old outputLink that targets the frame? I've
been thinking about trying to just use the tree in a struts app and if I
could put it in a frame and link to my jsp from it I'd probably save alot
of time.

Sean / Enrique
Actually in my case I have two html frames. In left frame I have a tree and
I right side frame I need to open the selected document (from tree).
Now my only concern is how to call a servlet when I click on document type
node
and hence I can open the document in right frame (I know the code of
streaming the document content).
If possible please guide me with some code snippest...
Below is my code snippet of JSF
<f:facet name="folder">
<h:panelGroup>
<h:commandLink immediate="true" style="text-decoration:
none;" action="#{t.toggleExpanded}"
actionListener="#{CabinetTree.processAction}">
<h:graphicImage value="/images/blue-folder-open.gif"
align="middle" rendered="#{t.nodeExpanded}"
border="0"/>
<h:graphicImage
value="/images/blue-folder-closed.gif"
align="middle" rendered="#{!t.nodeExpanded}"
border="0"/>
<h:outputText value="#{node.description}"
styleClass="nodeTree"/>
<h:outputText value=" (#{node.childCount})"
styleClass="childCount" rendered="#{!empty
node.children}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
<f:facet name="document">
<h:panelGroup>
<h:commandLink immediate="true" style="text-decoration:
none;" target="contents" action="test.jsp">
<h:graphicImage value="/images/document.gif"
align="middle" border="0"/>
<h:outputText value="#{node.description}"
styleClass="nodeTree"/>
</h:commandLink>
</h:panelGroup>
</f:facet>

You can also have a param whose value is the node identifier. That
is one of the uses I had envisioned for the identifier property (use
the documnet number as the node identifier.) Then just have your
command link point you to the servlet.
I think this is one of the cool parts of tree2. It is very
open-ended. You just use the standard approaches that work in other
situations. So there is nothing special about tree2 that you need to
know here. Take the same approach that you would with h:dataTable.

Re: submitting tree2 node to a serlvet
Posted by Enrique Medina <e....@gmail.com>.
Hi,
First you have to create the tree data (see getTreeData() method from
the examples) passing an extra parameter to the TreeNodeBase
constructor, in order to give each node an identifier (I have given
the page to navigate to, for example).
Then, indicate in the action of the commandLink component the following:
<f:facet name="document">
<x:panelGroup>
<x:commandLink immediate="true" action="#{myBean.menuAction}">
<h:graphicImage value="images/document.png" border="0" />
<x:outputText value="#{node.description}" />
<f:param name="action" value="#{node.identifier}" />
</x:commandLink>
</x:panelGroup>
</f:facet>
As you can see, you will have to define a method in your "myBean" bean
in order to be able to execute the action:
public String menuAction()
{
return (String) FacesContext.getCurrentInstance().getExternalContext()
.getRequestParameterMap().get("action");
}
Notice that you ask for a request parameter named "action", which must
match the name of the param you provided in the JSP view.
In my case, this method returns the identifier of the node clicked,
which is the page to go in the navigation model.
You will only have to provide different logic to that method.
Hope it helps,
Enrique Medina.
