1. Re: Load Data from database into Rich:tree(Very Very Urgent)
sarocks Oct 7, 2010 2:32 PM (in response to a.pradhan9049)Hi Ashutosh,
A nice example in the richfaces live demo page is here:
default tree model:
http://livedemo.exadel.com/richfaces-demo/richfaces/tree.jsf?tab=model&cid=124709
Don't bother about nodeSelectListener in that example. In the example data loaded from a file.
I hope you can do this way.
All the best.

sarocks Oct 11, 2010 5:28 AM (in response to a.pradhan9049)Hi Ashutosh,
You should be able to create Arraylists of String using the data from the database. Different Arraylists should be created for different nodes.
And as in example, you should able to add nodes to the parent nodes in for loop.
For example,
parent arraylist - Asiapacific, North America, Europ
child arraylist - India, China, Pakistan
subchild arraylist - ...
then in for loop, add Asiaspecific node to Global, then add nodes India, China, Pakistan to the parent node (Asiaspecific).
I hope you got it!
Sorry for my bad english.
Thanks,
Saroj

ahoehma Oct 11, 2010 7:15 AM (in response to a.pradhan9049)Hi Ashutosh,
I would do this:
1. Create a Domainmodel for the Data
Continent
--> a Name
--> have 0 .. n Land
--> a Name
--> have 0 .. m City
--> a Name
Continent.getLands() -> List<Land>
Land.getCities() -> List<City>
Continent.getName()
...
2. Create a JPA Layer for the Domainmodel (via Annotations)
@Entity, @OneToMany, ...
Store/Load via JPA
3. Display the Data via rich:tree
<rich:tree>
<rich:recursiveTreeNodesAdaptor var="continent" nodes="#{earth.continents}">
<rich:treeNode>
<h:outputText value="#{continent.name}"/>
</rich:treeNode><rich:recursiveTreeNodesAdaptor var="land" nodes="#{continent.lands}">
<rich:treeNode>
<h:outputText value="#{land.name}"/>
</rich:treeNode><rich:recursiveTreeNodesAdaptor var="city" nodes="#{land.cities}">
<rich:treeNode>
<h:outputText value="#{city.name}"/>
</rich:treeNode>
</rich:recursiveTreeNodesAdaptor></rich:recursiveTreeNodesAdaptor>
</rich:recursiveTreeNodesAdaptor>
</rich:tree>

a.pradhan9049 Oct 11, 2010 12:03 PM (in response to sarocks)Hi Saroj,
Thank you for quick response and solution.But one thing i want to understand from you i:e If i want to show the 10 level tree then i have to create 10 ArrayList and to get the data from DB we have to write 10 menthods as one method will return one arraylist at a time. So will it be acceptable Please suggest me .
Thnaks,
Ashutosh

sarocks Oct 11, 2010 2:07 PM (in response to a.pradhan9049)Hi again,
I think 10 arraylist is fare enough for the purpose!
As per your example different lists should exist for continent,country,states,city, etc.
i think you can create some logic in a method to put the arraylist data in the corresponding list. If you explain how the database list is generated, i can propose some way to do it.
Thanks,
Saroj

ahoehma Oct 15, 2010 9:28 AM (in response to a.pradhan9049)Hi Ashutosh Pradhan,
please think about "model" and "data" ... you post a example of "data" ... for this data you can create a "model" (OOP, objects, relations ...)
Gobal
Asiapacific -> Continent
India -> Land
Karnatak -> City
Orisaa -> City
China -> Land
Pakistan -> Land
North America -> Continent
Europ > Continent
for JPA please read here.
Regards
Andreas
