Populating JTree from database

Hi experts,
I need some feedbacks about the way i populate my JTree from database, Is there any better alternatives?
If yes, try explain it in detail.. I'm still new in Java.
Sample database table:
|       node_id      |       name      |       parent       |       hasChild      |
|         1          |     garbage     |        null        |           1         |
|         2          |       item      |          1         |           1         |
|         3          |      mouse      |          2         |           0         |
|         4          |       board     |          2         |           0         |
|         5          |       item2     |          1         |           1         |
|         6          |       item3     |          1         |           1         |
|         7          |       pants     |          5         |           0         |
-----------------------------------------------------------------------------------Here's the sample of my code:
//... ResultSet rs = .....
rs.last();
int rowCount = rs.getRow(); //Get the total number of row in database table
rs.beforeFirst();
int i = 0;
int j = 0;
String [] nodeID = new String[rowCount]; //The node ID
String [] parentID = new String[rowCount]; //A pointer to its parent ID
DefaultMutableTreeNode [] node = new DefaultMutableTreeNode[rowCount]; //The node
while(rs.next()) {
     String name = rs.getString("name");
     Boolean bool = rs.getBoolean("hasChild");
     node[i] = new DefaultMutableTreeNode(name,bool);
     parentID[i] = rs.getString("parent");
     nodeID[i] = rs.getInt("node_id") + "";
        //Set as root node when the pointer is null
     if(parentID.equals("null")) {
          rootNode = node[i];
     i++;
for(i=0; i<rowCount; i++) {
     for(j=0; j<rowCount; j++) {
          if(parentID[j].equals(nodeID[i]) && node[i] != null) {
               node[i].add(node[j]);
node[i] = null; //Obligates the parent after finish adding the child (to prevent unnecessary loops)
//... tree = new JTree(rootNode);
Thanks for the trouble,
Regards,
David

The execution time are base on the code i post'ed here.
Average over 30times using Vector = 640048 nanosecond to execute.
Vector<String> nodeID = new Vector<String>();
Vector<DefaultMutableTreeNode> node = new Vector<DefaultMutableTreeNode>();
Vector<String> parentID = new Vector<String>();
rs.last();
int rowCount = rs.getRow();
rs.beforeFirst();
k=0;
while(rs.next()) {
     String name = rs.getString("name");
     Boolean hasChild = rs.getBoolean("hasChild");
     node.addElement(new DefaultMutableTreeNode(name,hasChild));
     nodeID.addElement(rs.getInt("node_id")+"");
     parentID.addElement(rs.getString("parent"));
     if(parentID.elementAt(k).equals("null")) {
          rootNode = node.elementAt(k);
     k++;
i=0;
while(i<rowCount) {
     j=0;
     while(j<rowCount) {
          if(parentID.elementAt(j).equals(nodeID.elementAt(i)) && node.elementAt(j) != null) {
               node.elementAt(i).add(node.elementAt(j));
               if(!node.elementAt(i).getAllowsChildren())
                    node.insertElementAt(null,j);
          j++;
     i++;
}Average over 30times using LinkedList = 95623 nanosecond to execute.
//This section will have a class Nodes
LinkedList<Nodes> gather = new LinkedList<Nodes>();
while(rs.next()) {
     node = new DefaultMutableTreeNode(rs.getString("name"),rs.getBoolean("hasChild"));
     gather.add(new Nodes(rs.getInt("node_id") + "",node,rs.getString("parent")));
for(Nodes findParent : gather) {
     if(findParent.getParentID().equals("null")) {
          findParent.setRoot(findParent.getNode());
          rootNode = findParent.getRoot();
     for(Nodes findChild : gather){
          if(findChild.getParentID().equals(findParent.getNodeID()))
               findParent.getNode().add(findChild.getNode());
}As for the Array method i used from the previous post, the Average code execution time is x3 larger than the vector i used. So please do not use that method.
Note: 1. The code i post can be improved further. 2. Execution time is based on individual computer.
Well, I think i'll stop here. Anyone who wanted to know which method is more efficient currently, here's the answer.
Hope that it helps anyone who have the problem here =).

Building jtree from database query

I am trying to build a JTREE from a database result-set. The resultset is listed below. I'm thinking I can somehow build a dynamic array of objects to build a TreePath, then use that to build the JTREE. Any input is appreciated.
ResultSet Output:
Here is how the results would be retrieved from the database (including the order of the output).
usr 1
local 2
sbin 2 file4
bin 3 file1
bin 3 file2
logs 3 file3
tmpdir 4
The first column is the directory name, the second column is the directory/file level/position, and the third column is the filename, if one exists.
So from above:
/usr/local/sbin has file "file4"
/usr/local/bin has files "file1" and "file2"
/usr/local/logs has file "file3" and directory "tmpdir"
How could I gather this information into an appropriate structure and create a JTREE from it.
Thanks.
-Jim

So each line would:basically...
If I don't know the entire path of the parent (because I've read in a
line that only has the "one-up" parent name) .... However, when I
read the line from the database result-set, I don't know where "local" is.See... that's another problem with that data. Maybe you know cuz it's the last node if it's all in a proper order. In which case maybe you only need to hold the last parent node... Some recursive function would be useful.
If I were going to store the data, I would store either the name as a full path:
/usr
/usr/local
/usr/loca/bin
or
usr /
local /usr
bin /usr/local
If you have that, it might be easier to figure out without having to worry about what belongs where.

Creating dynamically JTree from database values

Hi,
I have a local database with some node values. I receive these values from database as a String[].
short example:
String[] Values = {"mainNode","Processors","mainNode","RAM","mainNode","Monitors",
"Processors","INTEL","Processors","AMD","RAM","Kingston","RAM","GoodRAM",
"Kingston","400MHz","Kingston","433MHz"}First value is higher node, second is a child.
I'd like to produce dynamically JTree from Values[] like below:
MainNode
|----Processors
      |----INTEL
      |----AMD
|----RAM
      |----Kingston
            |----400MHz
            |----433MHz
      |----GoodRam
|----MonitorsI can't build up any working and fast solution :(
Can anyone help me ?
Please for any advices (samples) which will help me to apply it.
Dearly regards!

This is a relatively straight forward task but it smacks of being homework so unless you post what you have already done you are unlikely to be given any code.
As a hint -
Go through the data creating a Map between the parent value and a child DefaultMutableTreeNode which contains as user object the child String.
When you extract a parent String from the data lookup the parent DefaultMutableTreeNode in the map and add the child DefaultMutableTreeNode to the parent DefaultMutableTreeNode.
Note - All the map is doing is giving you a quick way of looking up a DefaultMutableTreeNode given a parent name.
Note - that your tree will have problems if the same value appears in two or more branches!

Constructing Jtree with data from Database

Hi
I am new to JTree and I need some help. My problem goes like this. I have a table in the data base which has data like Folder_Nr, Folder_Name, Folder_Prev_Nr, Folder_Typ_Nr, Folder_Access.
If the Folder_Nr is 1 and folder_prev_nr =0, then it is a root folder and if folder no is 3 and folder_prev_no is 1 then it is a sub folder of the Folder_Nr 1. and so on is the data. I need to present all these folders in a JTree and be able to dynamically add and delete folders.
It will be of great help if anyone can provide me with some lead or some source code.
Thanking u in advance
BalaaP

Yes,using LiveCycle you could accomplish this easily.Once you have your invoice form ready based on predefined XSD, you can easily update the form data by fetching the values from database using JDBC operation.Also you could email this updated form using Email service.

Jtree examples of populating data from database

I have searched many of the solutions here, but the threads that contain examples of jtree loading from an sql database are not available. Does anyone have a good example of populating a jTree from the database?
Thank You

Hi,
AFAIK, there is no direct approach to populate a JTree directly from a resultset. However, JTree can use a DOM tree as its model by using the adapter pattern. The procedure to do this is well-documented in the SUN website and the link is provided below. The code to convert a resultset to XML is provided below:
protected void resultSetToXML(OutputStream out,
ResultSet rs,
String stylesheet)
throws IOException, ServletException {
// Create reader and source objects
SqlXMLReader sxreader = new SqlXMLReader();
SqlInputSource sis = new SqlInputSource(rs);
// Create SAX source and StreamResult for transform
SAXSource source = new SAXSource(sxreader, sis);
StreamResult result = new StreamResult(out);
// Perform XSLT transform to get results. If "stylesheet"
// is NULL, then use identity transform. Otherwise, parse
// stylesheet and build transformer for it.
try {
// Create XSLT transformer
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t;
if (stylesheet == null) {
t = tf.newTransformer();
} else {
// Read XSL stylesheet from app archive and wrap it as
// a StreamSource. Then use it to construct a transformer.
InputStream xslstream = _config.getServletContext().
getResourceAsStream(stylesheet);
StreamSource xslsource = new StreamSource(xslstream);
t = tf.newTransformer(xslsource);
// Do transform
t.transform(source, result);
} catch (TransformerException tx) {
throw new ServletException(tx);
The classes SQLXMLReader and other classes used in this example are available in the following java packages.
import java.sql.*;
import javax.sql.DataSource;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.sax.*;
import javax.xml.transform.stream.*;

</jsp:plugin>
if i view it in using AppletViewer it runs perfectly and display the data in JLabel. (ie, both jlblTitle and jlblNewTitle).(ie, DATA FETCHES FROM db AND DISPLAYS PROPERLY)
BUT IF I CLICK ON INDEX.JSP, ONLY jlblTitle APPEARS. jlblnNewTitle WILL BE BLANK(this label name is supposed to fetch from database)
EVERY THING IS DISPAYING PROPERLY EXCEPT DATA FROM DATABASE!!!

Build a JTree from data

Hello everyone,
I have to build a JTree from a table data from database. The table structure is
(id,parent_id,name). In order to build the tree, I have to the following 2 loop searching for the parent_id
while (i<size){
while(j<size){
//find it's parent_id
j++;
i++;
It is too slow! Can anyone help me?
Thanks!
--tc

You just add children to whatever the parent node is for that object.DefaultMutableTreeNode root = new DefaultMutableTreeNode();
child1 = new DefaultMutableTreeNode();
root.add( child1 );
grandChild = new DefaultMutableTreeNode();
child1.add( grandChild );
greatGrandChild = new DefaultMutableTreeNode();
grandChild.add( greatGrandChild );Etc.

Internationalized Object data from database

Hi...
I like to know which concepts you use in web application in case you need dynamic object data internationalized. For static web pages I can use ResourceBoundles to get the data but I'm still searching for the ideal way to do this with Object data.
Let�s say you have a Product object which has a name and description in many different languages.
Preferably I like to do something like this
<c:out value="${product.name}"/>
to display the users preferred (session) language, and for the special case to force a language I might use something like this
<c:out value="${product.name}" locale="en_US"/>
Now my big question is how should I implement something like this. Should the product.getName() method include the logic to determine the users session to call something like product.getName(Locale)? Or should I implement a custom tag to handle cases like this?
What is your preferred way of doing this?
Thanks,
Gregor

Open hyperlinks from database

Hi,
I have a table in database that has files uploaded from front-end like XLS, DOC, PDF,TXt etc.
I need to create a report that shows the filename as hyperlink and when user clicks the link, it should open the attachment in Excel if .XLS, Adobe if .PDF ..
Ex: Filename
Test.xls
plan.Pdf
roadmap.doc
Where all entries under "Filename" column is hyperlink and when user clicks hyperlink, it opens the appropriate document
Can we get this done in BI Publisher out of the box or do we need any custom code?
Advance thanks to everyone for their valuable feedback.

in my humble opinion it's not good solution
why in table? why not use bfile?
if you want select blob from your table you must always download it to some directory on server in sql/plsql way
or if you use, as example, c#client then you can download it as byte stream to client side
if you use bfile then your file stored on some server directory and you can work with by ftp, http as for ebs sample
so in this case you can't have problem with attachment, you can use url+filename in your report

Getting data in a combobox from database

I have done database connectivity in flex using .net. Now I am getting data in flex in a data grid. Everuthing is working fine if I take data in a data grid.
My problem is that if I try to take that data in any other control, other than data grid, it shows up no data, it only shows "object[object].
for ex:
if I am getting 3 rows from databse and I try to get those in a combo box, den I am getting 3 items in combo box like this:
object[object]
object[object]
object[object]
instead of actual data.
I am stuck in this problem for last 3 days. I have tried lot of things but nuthing is working. Plz anyone help me out soon. Its really urgent.
I am working on a live project and not able to proceed because of this problem.

Hi Bhavika,
You need to tell your combobox which value should be displayed in the ComboBox...for display...
You are getting 3 rows from database which are objects since you haven't told your combobox which value to be displayed it is displaying as [Object,Object]...
So you need to tell your ComboBox which values to be displayed ..and you can do this by assigning the labelField property of the ComboBox..
Say in your object you have three properties say..data, value, name...etc;;
Then if you want display name as your ComboBox display label then simply write ....labelField="name" in your ComboBox ...
Thanks,
