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..)

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 ?

ABAP Objects - Graphical Tree Structure

Hi All,
   I have a problem in splitting the container of graphical tree.
    i want to split the left side container which will generally have the tree hierarchy in small size, which can be viewed on the right side in a bigger size by positioning on the necessary portion of left side container.
   Please help me out as in how to split the container. is there any property which has to be set so taht it can be splitted.
Regards,
Theja.

Thejaswi,
You can do it in two ways. If you want only two divisions then you can use a EASY SPLITTER. If you more parts you can go for a SPLITTER CONTAINER.
w_custom_contnr TYPE REF TO cl_gui_custom_container,
w_split      TYPE REF TO cl_gui_easy_splitter_container,
w_contnr_top     TYPE REF TO cl_gui_container,
w_contnr_bot     TYPE REF TO cl_gui_container,
IF w_custom_contnr IS INITIAL.
Create Event Receiver
   CREATE OBJECT w_event_receiver.
    IF cl_gui_alv_grid=>offline( ) IS INITIAL.
      CREATE OBJECT w_custom_contnr
             EXPORTING container_name = c_container.
    Create the splitter control
      CREATE OBJECT w_split
         EXPORTING
           parent            = w_custom_contnr
         ORIENTATION       = 0
           sash_position     = 16
           with_border       = 0
         EXCEPTIONS
           cntl_error        = 1
           cntl_system_error = 2
           OTHERS            = 3.
    Get the containers of the splitter control
      w_contnr_top = w_split->top_left_container.
      w_contnr_bot = w_split->bottom_right_container.
    ENDIF.
    CREATE OBJECT w_tree
EXPORTING i_parent = w_contnr_bot.

Ravi

plzzz reply very soon..thanks

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

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.

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 '='?

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.

How to display graphics dynamically in JSP

I use JSP to call a servlet to get the output . The output is in svg format. I do not hope to create a svg file to store the output from servlet. I wope to embed the svg dynamically in the jsp page
Anybody knows the solution. Many thanks in advance
Cheers,
.

Because the output from Servlet is in text format not binary.
So the tag <IMAG></IMAG> does not work .
the output is similar as
<svg viewBox="0 0 360 270">
<style type="text/css"><![CDATA[
.aS{ font-family: monospace; text-anchor: middle;
font-size: 35px; stroke: Blue; fill: Red; }
]]></style>
<g>
<text x="60" y="90">+2%</text>
<polyline points=" 110,80 110,80 210,80 210,80" />
<text x="60" y="180">-2%</text>
<line x1="110" y1="170" x2="210" y2="170" />
<line x1="110" y1="120" x2="210" y2="120" />
<text x="280" y="130">4:0</text>
<text x="160" y="200">1</text>
<text x="110" y="150">-</text>
<text x="185" y="50">Sample - Name</text>
<text x="185" y="240">Minutes/km (2003/1/7)</text>
</g>
</svg>
If I keep the output as a **.svg file. then embed it in jsp. it is OK.

It goes upto 30000 records.
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.

Is it possible to do this in client side ?

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.

Illustrator Vector Graphics - TREES

Hi - Does anyone know where to get some trees for illustrator in PLAN view??

I think I found some by searching the USGS (United States Geological Survey) sites.
I know I found some
somewhere
but I forget where. It's been years.
Will these help (look through the PDF index):

But these are more probably what you're after:
