    Question How to create jtree which takes data from database in swing??

    I have a database table called Rubric which has records around 40,0000. This table has two column id and parent id like parent child relationship.
    I have to create a JTree using this table. example of rows :-

    ID parentID
    0 Blankl (Name Parent)
    1 0
    2 0
    3 1
    4 1
    5 3
    6 4.... onwards....

    When I fetch the data from table and create tree It takes very very long time around 4 to 10 min which can't be accepted.
    Please Advise me which approach should I follow.

    Thank you..

    Load your data lazily. Briefly, only load what needs to be loaded. Once a user expands a node, you then load its children. The following tutorial has a section on how to do this
