How to return to root node immediately

Hi,
In my repository manager, there're 2 kinds of navigation: folder-based and navigation-based. The user can change navigation type at runtime, while navigating inside a folder.
I plan to add a command (
extends AbstractCommand
) in the context menu for the user to choose navigation type. Now my question is, after changing the navigation type in code, how to show the root folder to the user immediately? I don't know its URL, or the URL of KM Content.
Thanks,
Ray

Hi Fallon,
Your answer is what I am looking for, but the URL doesn't work: /irj/go/km/docs shows the same page as /irj/portal. Am I missing some files on server, or the root URL for KM is another URL?
In my machine the root URL for KM is http://vanpgsap02:50000/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fadministrator!2fcontent_admin!2fcontent_admin_role!2fcom.sap.portal.content_admin_ws!2fcom.sap.km.AdminContentExplorer!2fcom.sap.km.AdminExplorer. I guess it's not what I want.
Waiting for reply.
Thanks,
Ray

How to handle unknown root node type when parsing?

Hello all, hoping someone knows how to accomplish this...
I'm trying to use XMLBeans to parse RIXML 2.0 documents. This schema allows for
multiple root node types, so I don't know when I'm trying to parse a file if the
root node is a Research node or a Product node, for example. If I try to invoke
parse and there is a type mismatch I get the following error:
com.bea.xml.XmlException: D:\RIXML\V2TestDoc.xml:0: error: The document is not
a Research@http://www.rixml.org/2002/6/RIXML: document element local name mismatch
expected Researchgot Product

Thanks,

Hello Joe -- You might try parsing the document as XmlObject (which your
schema-generated types extend). Then you could use an XmlCursor to discover
what the root element's local name is. Something like the following code
might be a way to do it. You could also simply re-parse the document after
discovering its root element name, but that would probably be more
expensive.
XmlObject xml = XmlObject.Factory.parse(mydoc.xml);
XmlCursor cursor = xml.newCursor();
cursor.toFirstContentToken();
if (cursor.getName().getLocalPart().equals("Research"))
// cast the XmlObject to your ResearchDocument type and use it.
else if (cursor.getName().getLocalPart().equals("Product"))
// cast the XmlObject to your ProductDocument type and use it.
cursor.dispose();

How to get the root node of a tree?

Initial JNDI context doesn't return the root node

Hi :
I just deployed a java application on Netweaver CE 7.2, when the application starts up, the code is trying to perform a JNDI bind and lookup operations by calling " Context context = new Initialcontext(), context.bind(), context.lookup("...)", the problem is that the initial context returned is not the root context (i.e. "/"), it's something like "webcontainer/applications/vendor-name/application-name/module-name/...." etc.. This is a problem for us because our application is consisted of multiple ears with multiple modues(wars) inside each ear, each module needs to publish a set of services as JNDI entries and those services (JNDI entries) need to be accessible to other ears or modules, which means they have to be published under some public directory (for exmaple the root directory), it can NOT be published under the current context of the current module.
So, my questions is, is there a way to make the "new Initialcontext()" to return the root directory, perhaps by changing the deployment descriptor or configuration settings somewhere? thanks a lot for your help.

Hi,
Add this code to the wdDoModifyView() method:
IWDRoadMap rdMap = (IWDRoadMap) view.getElement("<id of the RoadMap UI>");
rdMap.mappingOfOnSelect().addSourceMapping("step","selectedStep");
Edit the StepSelected action to add a parameter called "selectedStep" of type String. After this the signature for the action handler will look like:
public void onActionStepSelected(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, String selectedStep )
Inside the action handler you can access the selected step simply as "selectedStep".

How to create multiple root node in a tree

Hi Experts,
As per my requirement I have two requirements for tree creation:
1) Create a Tree which can display multiple root node.
2) Cretae a Tree which can display data directy without any folder.
I am new in Tree development.
Can any body help me out to get it done.
If it is not possible then also i need a confirmation from experts.
Regards,
Madhu

use method add_node of the class Cl_gui_alv_tree to add a node to the tree.
In case of root node the parameter lv_relat_key is passed as blank.In order to create further child nodes pass the node key of the parent as the relat key of the child and use the method again.

How to get the root node for a child using connect by prior

Hi,
I searched at many places to do this but not able to get the exact o/p sp posting my question here.
I have a table with parent_id and child_id columns. The levels of this parent_child can be many but my aim is to find the ultimate parent ( dont know the right term)
like if I have a child_node= xyz and its parent= pqr and its parents=lmn which might be ultimate parent which doesnt have any further parent.
So if i start with child_code= "xyz" then i should get the parent as "lmn" and not the immediate parent "pqr".
Please help.
Thanks,
Aashish

To find the Parent on emp table:
select empno,ename,level
from emp
where level=3
start with empno=7934
connect by empno= prior mgrTo find the Child on emp table:
select empno,ename,level
from emp
where level=1
start with empno=7934
connect by prior empno= mgrBut you need to know the level or position to specify the level of parent or child. But there are some other possible options available if we can know the requirement properly.

How to hide root node of hierarchy?

Hi,
can anyone give me a hint how to hide the root node of a hierarchy?
Thank you very much in advance, best regards
Frank

Hi Frank,
Another way would be to restrict the hierarchy in the query definition. Select all nodes, except the root. You can do the same in excel and save the query as a view. Of course, you have to maintain this selection every time the hierarchy gets new nodes.

How do i add a root node to a XMLType

Hi all
I have a problem inserting a root node in a xml document generated by DBMS_XMLGEN.newcontextfromhierarchy. The function get_site_map_nodes generates a document like this:
<?xml version="1.0"?>
<siteMapNode f_page_id="1" title="rot" PATH="1">
<siteMapNode f_page_id="2" title="1.1" PATH="1.1">
<siteMapNode f_page_id="4" title="1.1.1" PATH="1.1.1"/>
</siteMapNode>
<siteMapNode f_page_id="3" title="1.2" PATH="1.2"/>
<siteMap/>
</siteMapNode>
This is correct but i want to add a root node so the result shows as below:
<?xml version="1.0"?>
<siteMap>
<siteMapNode f_page_id="1" title="rot" PATH="1">
<siteMapNode f_page_id="2" title="1.1" PATH="1.1">
<siteMapNode f_page_id="4" title="1.1.1" PATH="1.1.1"/>
</siteMapNode>
<siteMapNode f_page_id="3" title="1.2" PATH="1.2"/>
<siteMap/>
</siteMapNode>
</siteMap>
The problem is that i have no clue how to accomplish this.
Best regards

Please try below steps.
1. Complete Prerequisite for adding cluster node
2. Verify the node is accessible to all other nodes in the cluster. Run the following command from the existing node in the cluster.
cluvfy stage -pre crsinst -n newNode
3. Run cluvfy from any existing node
cluvfy stage -pre nodeadd -n <New Node>
Note : If cluvfy in above step shows any errors fix those and then proceed with this step
4. Change Directory to Clusterware Home and execute addNode scripts from any existing node.
cd $CRS_HOME/oui/bin
./addNode.sh -silent "CLUSTER_NEW_NODES={ <NewNode > } CLUSTER_NEW_PRIVATE_NODE_NAMES={ <Interconnect >} CLUSTER_NEW_VIRTUAL_HOSTNAMES={ < Virtual Host Name >}"
At the end of addNode, script will prompt to run for root.sh on newly added node.
5. Verify Node is successfully added
cluvfy stage -post nodeadd -n <NewNode >
6. Verify CRS Stack is running on the new Node.
$CRS_HOME/bin/crs_stat -t
7. To extend the Oracle RAC Installation to include the new Node, run addNode from $ORACLE_HOME/oui/bin from existing node in the cluster
cd $CRS_HOME/oui/bin
./addNode.sh
When OUI displays the Specify Cluster Nodes to Add to Installation window, select the node to be added, then click Next .
Verify the summary and run root.sh on new node when it prompts.
8. Adding New Instance on the New Node
$CRS_HOME/bin/lsnrctl status
9.Run $ORACLE_HOME/bin/dbca from any of the existing RAC Instances Oracle Home.
Select Oracle Real Application Clusters database , and then click Next .
Select Instance Management , and then click Next .
Select Add an Instance , then click Next .
Click Next to accept default instance name or it can be changed.
Check the summary window.
Note: Please check these steps in test environment first.

How to change icon of a node or root node of a JTree

i have a JTree with a root node, and leaf nodes. i want to change their icons. how can i do this?
thanks

Here's a search of the forums with the words 'tree', 'icon' and 'node' in the title
http://onesearch.sun.com/search/developers/index.jsp?and=jtree+icon+node&nh=10&phr=&qt=&not=&field=title&since=&col=devforums&rf=0&Search.x=28&Search.y=15
I looked at a couple and #5 seems interesting, but there are quite a few to choose from.

How do i get to display the nodes under the root node in a JTree?

In my JTree there is a root node.This root node has 4 child nodes.Each child node in turn has nodes under it.What i need to do is just display the child nodes under the root node i.e., the four child nodes and keep these child nodes in a collapsed state.How do i go sbout this?

Please try this:
tree.expandRow(0);
SwingUtilities.invokeLater(new Runnable(){
    public void run(){
        tree.setRootVisible(false);
});If you want to show the RootHandles:
tree.setShowsRootHandles(true);If you want to keep nodes in collapsed state (not expandable):
        tel = new TreeWillExpandListener() {
            public void treeWillExpand(TreeExpansionEvent event) throws ExpandVetoException {
                throw new ExpandVetoException( event, "Don't want" );
            public void treeWillCollapse(TreeExpansionEvent event) throws ExpandVetoException {
        tree.addTreeWillExpandListener(tel);Some reading material:

Thanks in Adv.
Thanks ,
Kranthi Kumar M.

Hi Kranthi,
For your requirement you need only two nodes. Root Node and Result node. Use the same structure for both.
To create Instance while search.
Create Query method with input type which has the required fields for selection criteria.
Fetch the data and create instance in the root node.
Pass the new instance key as exporting parameter form Query Method.
To Move data from ROOT to Result.
Create a action at root node.
Write a code to create new entries in Result node.
Then configure the Search UIBB and display result in List UIBB. Add button and assign the action MOVE_MAT_2_RESULT.
Create another List uibb to display data from Result node.
Connect the UIBBs using wire schema. SEARCH -> LIST(ROOT) ---> LIST(RESULT).
Give src node association for ROOT to RESULT Configuration.

Sunil

How to disable selection of root node in JTree

Hi all! Thanks for taking a minute to read my post!
I am writing a really basic JTree for showing a list of items.
Here is some of the code:
/** Create a basic tree **/
DefaultMutableTreeNode rootNode = new DefaultMutableTreeNode("Title");
DefaultTreeModel treeModel = new DefaultTreeModel(rootNode);
JTree tree = new JTree(treeModel);
/** Method to return the string of the current highlighted selection **/
public String getSelectionString()
DefaultMutableTreeNode node =
tree.getSelectionPath().getLastPathComponent();
return (String)node.getUserObject();
I would like to disable selection of the root node of my JTree.
Thus, if I make a call to getSelectionString() above, it would return null instead of the string that represents the root label.
I have read the following forum on disabling various TreePaths and TreeNodes in a JTree:
http://forum.java.sun.com/thread.jsp?forum=57&thread=224691
This forum suggests implementing the TreeSelectionListener interface and the TreeSelectionModel class and over-riding the addSelectedPath() methods. I tried this suggestion, and I was able to enable and disable the different children of the Jtree, but the root of the JTree would not disable.
I suppose that I could just simply remove the visibility of the root node, but I really want to avoid that option if possible.
Wait --- let me be clear ---- I want to disable the selection of the root node only - still allowing selection of all its children.
Any suggestions?
Am I missing something really simple here?
Did I explain my problem clearly?
Thanks in advance!
jewels

simply try this..
in the
public void valueChanged(javax.swing.event.TreeSelectionEvent event);
method of TreeSelectionListener impelentation get the
TreePath tp = event.getPath();
from TreePath get the component and then remove the selection from the treePath if it is the node u were checking/root node in this case
tree.getSelectionModel().removeSelectionPath(tp);
Try out....

How to remove all nodes (except root node)from a Jtree?

How to remove all nodes (except the root node)from a Jtree?

Either:
- remove all children of root.
- save the root node, throws away the tree model, build a new TreeModel with the saved root, set the new TreeModel in the JTree.
- implement your own TreeModel, which would support an emptyExceptRoot() method.
IMHO, using the DefautlTreeModel and DefaultMutableTreeNode does lead to all sorts of small problems when the app evolves, and implementing your own TreeNode and TreeModel is not that hard and much more efficient.

ADF Tree: how to access root node after "Show as Top" selected on sub node

I am currently working on a project that using ADF tree and implementing some search/filter functionality. I need to find the java API calls to get the new root node information after UI user select a sub node in the tree and clicked “show as top"(so search are done only on the current tree. Can someone help on this?

Hi ,
In our project we require to implement ADF menu tree inside <af:menulist>.
We require to show 3-4 child menuitems inside 2 parent menus.
Home
--> Inbox
-->Search
Patient
--> Information
--> Search
Can you please tell steps to implement <af:menutree> to have child menuitems like Inbox, Search inside parent like Home ? I searched on ADF sites but not much of help there.
