how can i delete the root node from a tree ???
i've tried:

this removes all nodes from the tree except the root.
thanks.

try this:

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.

Can't remove a node from a tree

I am using the custom tree dataDescriptor provided in Flex live

This is my tree definition:

dataProvider="{ac}"
defaultLeafIcon="@Embed('assets/caseIcon.png')"
change="publicTreeChanged(event)"
dragEnabled="true"
dragMoveEnabled="false"/>
This is how I remove the selected node from the tree. When
Delete button is clicked, the doDeleteCase function is
exectuted.
public function publicTreeChanged(event:Event):void {
selectedNode =
publicCaseTree.dataDescriptor.getData(Tree(event.target).selectedItem,
ac);
public function doDeleteCase(event:Event):void{
publicCaseTree.dataDescriptor.removeChildAt(publicCaseTree.firstVisibleItem,
selectedNode, 0, ac);
Any help would be appreciated.Thanks.

Finally I removed nodes from tree, but not sure I did in the
right way. Anybody encounter the same problem, please
discuss.

How to Remove a Node from JTree?

I want to remove a node from a JTree but the node may or maynot be visible.
My method takes a String which is the name of the node.
The nodes im using are DefaultMutableTreeNode
This is my code so far but it doesnt work.
public void removePerson(String pName)
          TreePath node = tree.getNextMatch(pName,0,Position.Bias.Forward);
          tree.expandPath(node);
          tree.removeSelectionPath(node);
}Any Suggestions or ways which i could achive this?
Thank you,

I don't think removeSelectionPath is what you want to use.
These should help:

How can I remove child node from JTree???

Hi,
I would like to remove all the child node of my jtree. For instance I would like to remove the c, d, and e nodes. It's possible to remove all the child node or to remove by her name ("c", "d", and "e"). If yes what is the method that it permit to do.
A-----
|
b-------c
|
|--------d
|
---------e
I use the model : DefaultMutableTreeNode
Thanks

There are a couple of ways it can be done. If your tree uses DefaultTreeModel as its TreeModel, you can use removeNodeFromParent(). This will remove the node from its parent and effectively remove its children, too. All nodes removed will be garbage-collected if there are no other references to them.
If your tree model is not the default tree model, but still uses MutableTreeNode, you can use either remove() or removeFromParent() on the node itself, depending on whether you want to remove the node itself or one of its children.
On the other hand, your tree may use a model that simply "mirrors" another data structure, in which case you would have to remove the node from the other data structure and have it reflected in the model.

How to remove a node from nlb at runtime?

hello,
i need to temporally exclude a node from an nlb.
May happen that a server is up and working but the web application i'm balancing is out of sinch with the same application in the others nodes.
Eg. some static variables are not the same of the same static variables of other nodes, because of a timeout, a write error and so on but the server is still working.
in this case i need to stop the server from nlb because the information in the web application is not in sinch with other nodes.
I need to prevent users from being serverd from this out to date server, untill it will became updated, but i need to do this programmatically
how can i do it?

How do I remove a node from Always on Availability Group in SQL 2012

Hello I was wondering if anyone could tell me to remove a node from an AOG group in SQL 2012. We currently have a two node Always on availability group and I need to replace one of the servers. My plan is to bring the
new server on to the group then remove the old server and I am having issues finding documentation on this. Could someone explain how to do this or if it is even possible.
Thanks

After the new server is added to the cluster and the AG, remove the old one by first
ALTER AVAILABILITY GROUP [YourAG]
REMOVE REPLICA ON N'OldServer';
Remove a Secondary Replica from an Availability Group
Then evict the old server from the cluster with the cluster administrator or
Remove-ClusterNode OldServer
Remember to verify the quorum configuration after adding the new server and removing the old server.

How to remove a node from a target xml payload in reciever file channel

i have a scenario where i have to remove a node from my target xml file in receiver file channel and want xml as the output file. I don't want a fixed length file. How to do that in receiver channel? Do we need to use file content conversion for that?

that will result in giving you a fixed file or a separator defined file.
it will not give you an XML file.
In case you want a XML file, instead of using variable substitution, use Dynamic configuration and adapter specific properties.

It goes something like this, taken from the above blog entry:
Removing a node from node-list
With the bpelx: extensions in BPEL you are able to insert and update nodes in a node list. A node-list is an XML message that contains a set of records. In this article I use the following example:
<BookList xmlns="http://message.vijfhuizen.com">
<Book>
<title>The Lord Of The Rings</title>
<author>J.R.R. Tolkien</author>
</Book>
<Book>
<title>Harry Potter</title>
<author>J.R.R. Tolkien</author>
</Book>
<Book>
<title>The Hobbit</title>
<author>J.R.R. Tolkien</author>
</Book>
<Book>
<title>Storm; Chronicals of Pandarve</title>
<author>Don Lawrence</author>
</Book>
</BookList>
For creating and updating node lists the bpelx: functions are enough to handle this. But when you want to remove a particular node, you can use the bpelx:remove function. But this function can only remove a node from a particular position. For example removing the second node you code:
<bpel:assign>
<bpelx:remove>
<bpelx:target variable="VarBookList" query="/Booklist/Book[2]" />
</bpelx:append>
</bpel:assign>
It is hard to code the bpelx:remove to create a xpath to dynamicly remove node. You would like to remove the second node based on the xpath:
/Booklist/Book[title="Harry Potter" and author="J.R.R. Tolkien"]
You can add the above xpath in the bpelx:remove, but you are not able to make this dynamically.
There is a solution. The trick is to create a stylesheet that copies the data into a new message, but removing that particular records. Create a stylesheet that does the normal copy of the XML message. Then add a <choose> element in the stylsheet to filter that particular record.
<xsl:template match="/">
<BookList>
<xsl:for-each select="/BookList/Book">
<xsl:choose>
<xsl:when test="title='Harry Potter' and author='J.R.R. Tolkien'"/>
<xsl:otherwise>
<Book>
<title>
<xsl:value-of select="title"/>
</title>
<author>
<xsl:value-of select="author"/>
</author>
</Book>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</BookList>
Now we have a XSL stylesheet that removes a particular record, but this is not variable. This can be done via XSLT parameters.
<xsl:param name="pTitle"/>
<xsl:param name="pAuthor"/>
<xsl:template match="/">
<BookList>
<xsl:for-each select="/BookList/Book">
<xsl:choose>
<xsl:when test="title=$pTitle and author=$pAuthor"/>
<xsl:otherwise>
<Book>
<title>
<xsl:value-of select="title"/>
</title>
<author>
<xsl:value-of select="author"/>
</author>
</Book>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</BookList>
</xsl:template>
Now we are able to use this stylesheet in BPEL. In general BPEL create the following code:
<assign name="Transform">
<bpelx:annotation>
<bpelx:pattern>transformation</bpelx:pattern>
</bpelx:annotation>
<copy>
<from expression="ora:processXSLT('RemoveNode.xsl'
, bpws:getVariableData('Variable_BookList','payload')" />
<to variable="Variable_BookListTemp" part="payload"/>
</copy>
</assign>
But this code does not pass parameters to the stylesheet. The ora:processXSLT() can do this it has an additional parameter in this function:
<assign name="Transform">
<bpelx:annotation>
<bpelx:pattern>transformation</bpelx:pattern>
</bpelx:annotation>
<copy>
<from expression="ora:processXSLT('RemoveNode.xsl'
, bpws:getVariableData('Variable_BookList','payload')" />
, bpws:getVariableData('BPELxslparameters'))"/>
<to variable="Variable_BookListTemp" part="payload"/>
</copy>
</assign>
Now only you have to create the BPELxslparameters variable and assign it with the correct name/value pairs. The structure of the this variable is as follows:
<?xml version="1.0" encoding="windows-1252" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://schemas.oracle.com/service/bpel/common"
targetNamespace="http://schemas.oracle.com/service/bpel/common"
elementFormDefault="qualified">
<xsd:element name="parameters">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="item" minOccurs="1" maxOccurs="unbounded">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="name" type="xsd:string"/>
<xsd:element name="value" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
Create in BPEL the variable BPELxslparameters and let it point to this strucure:
<process ....
xmlns:common="http://schemas.oracle.com/service/bpel/common"
.../>
<variable name="BPELparameters" element="common:parameters"/>
Now we can in BPEL create an empty XML message, based on this strcuture and assign the values to these parameters and then call the processXSLT function.
<bpelx:assign name="Assign_GenerateEmptyParameterSet">
<copy>
<from>
<parameters xmlns="http://schemas.oracle.com/service/bpel/common">
<item>
<name>pTitle</name>
<value/>
</item>
<item>
<name>pAutor</name>
<value/>
</item>
</parameters>
</from>
<to variable="BPELparameters" query="/common:parameters"/>
</copy>
</bpelx:assign>
<assign name="Assign_setXSLTParameters">
<copy>
<from expression="'Harry Potter'"/>
<to variable="BPELparameters" query="/common:parameters/common:item[1]/common:value"/>
</copy>
<copy>
<from expression="'J.R.R. Tolkien'"/>
<to variable="BPELparameters" query="/common:parameters/common:item[1]/common:value"/>
</copy>
</assign>

Removing live nodes from cluster view.

Hi All,
          We are experiencing some JMS problems connected with a cluster node being
          hung for some time.
          The following took place just before the problem arises:
          1. First of all one of the nodes (the first) gets one thread
          (weblogic.jms.backend.BEPushRequestSender@76512c) stuck.
          2. After that it closes the TCP connection to another node and
          3. Removes another node from its cluster view.(that is alive)
          4. After that the second node removes the first from its cluster
          view.
          5. Seconds later they find each other again and add each other to the
          cluster view.
          6. After that, the JMS distributed members are connected to each other,
          7. Something strange happens, because either the first node starts
          missing many messages in its distributed topic member or the second
          node doesn't propagate messages from distributed topic to the first
          node.
          Is it possible to set up weblogic cluster in a way, it won't remove
          other members from cluster view by peer gone exception, only by
          heartbeat timeout? Is heartbeat retry time parameter is configurable?
          Any help with this matter will be greatly appreciated.
          Dmitry Finkelstein


You must run the update node list for each ORACLE_HOME on that machine. If this is RAC, the runInstaller will take care to update all nodes, so again, you run it once per ORACLE_HOME installed.
Shared Home is a single copy of the Oracle software, rather than each node holding their own copy of the software. There's a paper that talks about these two topics and gives some examples of full commands on OTN:
http://www.oracle.com/technology/products/database/clustering/index.html

Enjoy and hope this helps.

How To Remove Empty Node From Source XML

Hi,
How can I remove an empty node from the source xml in a XSLT mapping.
For e.g. If the source xml is like:
<SRC>
<Node1>SAP</Node2>
<Node2/>
<Node3>XI</Node3>
</SRC>
Then the xml should become:
<SRC>
<Node1>SAP</Node2>
<Node3>XI</Node3>
</SRC>
I need to do this because the output of my XSLT mapping is showing blank spaces for each blank node.
Thanks,
Abhishek.

Use <xsl:if>
Or else you may find different options here

I should find the child and if this child has a child to shift with the parent to another tree, there are no tools or function can return the child of the node? Or what is the best procedure to do that?
I will be thankful if there some one can help me
Regards

You can grab the data with ftree.populate_group_from_tree and then use ftree.add_tree_data to put it in another tree.
