Urgent : Trees in JSP

hii guys
i am very new to jsp..i want to display a employee hierachy structure( who reports to whom)..
current i am using java swing tree and loading it in applet..but this is giving me problem because of the large size of driver file..
i would like to know if i can embed swing tree or any other tree which jsp supports.i want to update the tree dynamically i.e when the user clicks on a employee i wnat to expand it to show who reports under him...
plzzz reply very soon..thanks
sairam

JSP has no native support for displaying trees. Hence I have created a tag library to solve the problem

Exercise / display tree in JSP

Until recently, I though it was not possible to display a tree
with JSP pages unless using some "external" code [tag,js,etc.] for
generating the HTML.
So I propose you a little challenge:
- display a tree [for example a directory structure starting from a given directory]
- in a nested form
- with no library tags
- without direct use of "out"
- <%= ... %> only allowed to display file names
- with a single JSP

what you want ommit is all the advantage of the jsp:(()
without those, why people use jsp?My purpose is only to demonstrate that it is possible to display
a nested structure with "simplistic" JSP. So, will you take up the challenge ?

Graphical tree in JSP

I wanna write a code that will allow users to make a tree structure at runtime, it must be a web based server site most preferably in JSP

cotton.m,
Unless you are planning to use an applet this won't be happening.Exactly and this is what happened to me when I tried to implement table tree in jsp and javascript, after several approach; it turn out the is no way of controlling the view; then I moved to build the Report based on applet
You don't seem to be aware that JSP code executes on the server. And produces something like HTML. Which is then viewed in the browser.Yes and It is not easy to handle the event on the browser to the server; especially if you want to use one component from Struts or any rich client interface framwork, you will end up adding the whole libraries and different configurations etc.. so there is not light weight approach to extract what you need from these frame work (ZK, Struts, Myfaces etc..)

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 '='?

Please help me out .its very urgent.
Thanks in advance.

Have you actually been able to get this to work? I tried some of the demos from the MS site and running the html file with the treeview.htc just sends my browser into a state of loading with nothing happening!?!
This is a webcontrols component which is rather MS specific. As for finding the namespace, are you accessing this page locally or remotely? the namespace location, if run from a JSP, will resolve the C: drive to the one the web browser is running in not your server.
If you have your htc file in the same dir as the jsp your running, then putting just "treeview.htc" as the namespace whould be fine or add the context path like so:IMPLEMENTATION="<%=request.getContextPath()%>/treeview.htc"Let me know if you actually get this running without a web server. Otherwise it may be the .Net server that renders the page.

This is the jsp that displays the tree, you can either manually code the SPAN_IDs to include watever u want in the tree or you can get the contents of the tree from the database.

JS Tree Browser - JSP

I have inserted a JS Tree Browser Data Web Bean in a JSP page but it doesnot works!! This is the result:
"Rowset must be self-referential and ViewLink accessor must be defined"
... What should I do??...
Thanks!!
Johary Pirez.

You need to prepare the query using the setWhereClauseParams(x) call, before you initialize your data web bean. Otherwise, if you call the methods after you initialize your web bean, the context has already been set and the error occurs.
You should insert another data web bean into your page somewhere at the top and use it to setup your query and create a view object. You should remove this bean's Render() method since you are only interested in the Initialize() method here. Add your code to prepare the query and create the view object.
Then when your JS Tree Browser executes, it will be able to call getRowSet() on the View Object you created already.

Hierarchical trees in jsps

Hello:
Does anyone have any sample code that shows displaying a
hierarchical tree from a jsp page?
We're new at jDeveloper and are using xml and xsl
stylesheets.
We cannot use the swing control as this requires the client to
download a 2mb file to their computer.
Any advice, samples or links for a solution would be greatly
appreciated.
Thanks.

Using tag library to create a tree in jsp

Hi,
I want to create a tree in a JSP page whose node values are obtained from the database. The number of children of a particular node is known only during the construction of the tree.
Root
|---Node I
|----Node I Level 1 Child 1
|----Node I Level 1 Child 2
|----Node I Level 1 Child 2 SubLevel Child 1
|----Node I Level 1 Child 2 SubLevel Child 2
|---Node I Level 1 Child 2 SubLevel Child 2 Subsub Level1
|----Node I Level 1 Child 3
|---Node I Level 1 Child 3 SubLevel Child 1
|---Node II
|---Node n
These node values are obtained from the database. Any early help is appreciated. Helping in tree construction using JSP & Tag Libraries is requested (not swings). Also help me in deploying the same in Tomcat 4.0 server.
Regards
Vimal

I am not very knowledgable in tag libraries. Bust using pure java, you can do something like this:
Create Node and NodeRenderer java classes. These classes will have methods to access their siblings, parent and its properties and to render itself using HTML code. When you read the database to retreive the tree structure, you can build a hierarchy of nodes. Each Node can render itself and by doing an appropriate traversal, the tree can be rendered.

URGENT help with JSP

Any help with this will be really appreciated. I'm new to programming.
If I search for an ssn in a database, I want to view all records relating to that ssn. However, I am getting all the records in the table.
eg.
at the prompt for ssn, let's say I enter 111111111
I would like to see
111111111 abc xyz etc
111111111 pdg ppp etc
however, I am getting
000000000 utt tui etc
111111111 tug etg etc
How do I make limit the search to the ssn I want?
The related code is below.
Thanks.

<TD><%= sStmyType %></TD>
<TD><input TYPE="checkbox" name="<%=rowID %>" ></TD>
<% MyTaxSuppress = MySuppressTaxList.getNext(); %>
<% } // end of while loop %>

I don't see anywhere in your code where you conditionally output a tuple from your database. You seem to be outputting everything.
Maybe you need:
<% if (sSSN==input_value){ %>
<TD><input TYPE="checkbox" name="<%=rowID %>" ></TD>
<% } %>

The Oracle Jinitiator is no longer supported and is not compatible with newer browsers. I recommend you configure your system to use the Oracle/Sun Java Plug-in (Java Runtime Environment-JRE) 1.6.0_18 or higher; but not Java 7. Last I had heard Java 7 was not certified/supported with Oracle Forms; but that may have changed.
To use the Java 6 plug-in, take a look at the Oracle White Paper Oracle 10gR2 Forms Services – Using Sun's Java Plug-in. This document will show you how to configure your system to use the Oracle/Sun Java Plug-in.
As for upgrading your Forms version to the 10.1.2.3.0, Christian is right, you can only get the patch from My Oracle Support and you must have a support contract with Oracle.
Hope this helps,
Craig B-)

Urgent Help in JSP for multiple records update

I have a Order Placement form for the dealers. Here they place their orders online and submit the form. The details they enter are stored in Orders table in a database. This order is sent for processing. This is an external operation for the users of our products.
This table has two extra fields AccptNo and DelDate, which are filled in by the Admin of the Stores Dept of our company. The Admin then logs in and views the new orders. He sees the new orders displayed in the following format. The data shown is from the Orders table.
He is then reqd to just fill in the Accpt No and Del Date against the requisite Order.
Having finished filling up all the details he clicks the Submit button which updates the Orders table. i.e the existing records are updated with the accptno and del dates or rather the records are overwritten.

Name your textfields for accetance number and del date as your primary key that must be dealer id in your case.
You can do this by writing <input type=text name=<%=<something>%>>
Then you can get all the parameters in jsp to which you are going to submit your request by using function getParameterNames(). That will return you all the primary keys posted as name of your textfield. Then get the parameter value from parameter name and run the sql.

User enters the text and presses submit button the
coresponding text has to be searched in the tree structure
and that has to be made selected.
all the parent node which has the text as child has also
to be populated in the List box. how can I do this.
Is it possible to do this in client side ?
I want help ?

Internet Explorer 5 can do it on the client-side. it uses the Active-X plugin as a DOM parser....and you can use javascript with it.

URGENT: sp6 and JSP compiling/classpath problem?

Hi,
          We installed sp6 on our production site a little over a week and started
          seeing this problem on our logs with regards to any JSP with an include tag,
          such as:
          <%@ include file="/inc/insideHeadTag.jsp" %>
          INTERMITTENTLY, we will get the following error in the page on the client
          side at runtime:
          < ! -- cannot include file '/inc/insideHeadTag.jsp', resource not
          found -- >
          I grepped this newsgroup and noticed a previous unanswered post of the same
          nature, "Static compiles do not seem to include JSP's". Except in our case,
          this problem also manifest for dynamic JSP compiles, happens sporatically,
          and only started with sp6.
          Bug???

          Just to clarify - I'm not from BEA, I'm from EA - short a letter.
          As far as I know, there is no synchronization between WL instances in a cluster regarding the
          the compiling of JSPs. So when you start up two WL instances that share the same workingDir,
          and each WL instances gets a hit on your shiny new index.jsp, they both need to compile it. So the first
          one compiles it and writes index.class, the second does the same, overwriting the first _index.class,
          possibly at the same time that the first instance is trying to load _index.class into memory. And you
          get a mysterious 'class not found' error. Not likely, but possible.
