Urgent help, Tree Viewer JSP

Has anyone gotten the tree viewer bean to work on a JSP? If so, please give tips on it, or an example of table would be appreciated. I keep getting an error message that my row-set browser is not self-refferencial.
Thanks

hi vidyut, thanks for the help. was juz wondering. The file contents tt im supposed to read in and print out contains around 200 similar entries, meaning :
MEASURE Waist_Full=33.19
MEASURE Waist_Front=16.06
MEASURE Waist_Back=17.12
MEASURE Waist_Height_Front=38.82
MEASURE Waist_Height_Back=39.73
MEASURE Waist_Height_Left=39.28
MEASURE Waist_Height_Right=39.28
MEASURE Waist_Front_X=43.98
MEASURE Waist_Back_X=35.04
MEASURE Waist_Width=11.85
MEASURE Shirt_Collar=14.88
MEASURE Neck2Waist_Front=19.64so is the properties object stil the best method to use? To extract the whole string except MEASURE and '='?

Urgent help is needed - JSP & Java beans

Hi,
I am getting the following problem when trying to interact with Javabeans from JSP (DB I use is Cloudscape) :
An exception occurred while interacting with the guestbook database.
The error message was:
Cannot create bean of class proj.beans.UserDataBean
Please try again later
The problem probably occurs in following line:
status = guestData.checkUser(userName,emailName);
where guestData represents a Javabean class.
The strangest thing is that sometimes, suddenly, the program is working OK without this Error Message but when it occurs I don't know the reason and how to solve it.
Please advise...
Thanks a lot.

Can you copy the entire stack trace and post it? It would probably help.

Urgent help needed in JSP...

Please let me know your solutions as soon as possible.
Thank you,

Thanx a lot.
I did understand how to use session to store a java object. Actually, I wanted to use primitive data types... well, I could work around that.
But, could you please explain what you mean by storing in the application context?
Thanks a lot,

Please Help(How to get RadioButtons in tree View)

Hi.
Sub/Requirement: How to implement RadioButtons in tree view with/without using xml file.
I have a requirement like this i want to display RadioButton in tree view.
I implemented tree same as which is given in sampleApplications.
In this sampleApplications they implemted tree by using xml file.
I also implemented tree by Generating xml file. In this xml file i get the values from the database. I am using <netui:tree > tag.
Is it possible to implement tree without using xml file. I need to generate tree Dynamically.
Please any one help me to come out with this solution.

The issue here is while you are retrieving all the details, you are consistently overwriting them in the request.setAttribute() call before you get to the JSP to display them.
Do you actually have a class/object called Student?
That object should have attributes for classes, subjects, teachers (all of which are lists apparently)
public class Student{
String name;
List classes;
List subjects;
List teachers;
// appropriate getter/setter methods
}Then you load each student, and populate its individual lists.
That lets you pass the list of students, each student having its own lists for display.
Hope this helps,
evnafets

How to display an xml file contents in jsp as tree view

hi,
Iam trying to read an xml file and display the structure in jsp as tree view, can any one help me

Use a [XML or DOM parser|http://java-source.net/open-source/xml-parsers] to read a XML file into a tree structure of Java objects.
Use the [Collections API|http://java.sun.com/docs/books/tutorial/collections/index.html] to get hold of the relevant elements in a tree structure.
Use JSTL´s [c:forEach|http://java.sun.com/javaee/5/docs/tutorial/doc/bnakh.html] tag to iterate over a Collection in JSP.
Use HTML´s [<ul>/<li>|http://www.w3.org/TR/REC-html40/struct/lists.html#h-10.2] or [<dl>/<dt>/<dd>|http://www.w3.org/TR/REC-html40/struct/lists.html#h-10.3] tags to represent a tree in HTML.

A tree-view in HTML page with nodes generated with java script in run time is not visible in the UI Automation Tree. Need Help

I have a HTML page with an IFrame. Inside the Iframe there is a table with a tree view
<iframe>
<table>
<tr>
<td>
<treeview id="tv1"></treeview>
</td>
</tr>
</table>
</iframe>
In UIA, i am able to traverse till the tree view but not able to see it.
I have used the TreeWalker.RawViewWalker Field to traverse the node from the desktop Automation.RootElement.
I tried to use AutomationElement.FromPoint method to check whether i am able to get that element. Fortunately i was able to get the automation element.
i tried to get the path to root element from the node element using the TreeWalker.RawViewWalker. I was able to get the parent path to the root element.
But trying the reverse way like navigating from root element to tree node, was not getting the element for me.
Please help me with suggestions or inputs to resolve this issue.

Thanks Bernard,
It works fine with JInitiator but not working with
the JPI. For JPI what settings I need to do ??hi TKARIM and Bernard, i am having similar problem even with the Bernard's recommended setup. could you post the webutiljini.htm (i presume you are using config=test) ?
i am actually using jinitiator 1.3.1.28 with Oracle HTTP Server of OAS 10gR2) calling Forms Server 6i (f60cgi). After setting up according to Bernard's recommended setup steps, the java console showed that it loaded the icon jar file when it could not read the form, but it skipped the loading of the icon jar file once it read and started the form. How do we specify in the form to pick up the icon from the jar file instead from a directory ? Or do we need to specify ? Any ideas ?
Thx and Regards

Tree View through JSP and Java Script

Hi,
I am looking for code or ideas of a Tree Structure as shown in in the left side frame of admin console of Sun App server 7 on the browser. I need to create a tree structure which will work on the browser like it works on the Sun App Server 7 admin console. If you had any idea or code, please share with me. I would like to have some idea before I start building it. The tree will be build from the database. So any database design is also helpful. I am planning to have that tree using JSP and EJB.
Please help. If you are not clear what I am looking for, then please drop a line in this forum, so that I can explain it fine.
Thanks in advance.
Amit

You can use the JSP Tree Tag I have developed. This helps you both structuring the tree model itself + it takes care of displaying the tree in a nice way. You can change all HTML code used to display the tree. Also you can build trees dynamically instead of just displaying static trees. Take a look at it here:

hello pradeep,
for adding icons in the tree, u willhave to look closely to the
data format for the tree.in the data format used for populating
the tree we are supplying 5 fields. the state of the tree node
(expanded or collapsed), the depth of the node w.r.t the parent
node, the node value, the node label(what we see on the tree)
and the node icon which we want to use. for the node icon we
have to provide the entire path of the icon file. that's it.
hope this will solve the problem

Menus, Tabs and Tree Views I need some help

heya,
I am quite new here! I was searching desperately on a solution on how to fix my code. I need to do a menu in Java and bellow two boxes, one in which I will display a static tree structure (on the left side of the window) and one where I have some tabs (on the irght side of the window).
Now, today I was playing around with the tree structure view and also trying to use modules in my code for a more easy debugging and understanding later on and I managed to screw up the functionality for good :D.
Please some help, where am I going wrong and what is missing in my application.

Suggestion: Mark "Helpful" & "Solved" Posts As Such in Tree View

The subject line says it all pretty much.
It would be helpful if, when viewing a thread in Tree View, one could easily pick out which, if any, posts had been marked "Helpful" and "Solved" by the OP.
Thank you.
