Hi Venkat,

I experienced the same probelem as yours too. In my case, after i am sure that connection setting is correct (in Eclipse) I restarted my Eclipse everything ok.

one suggestion, try to sniff the sql query that Eclipse send to ur dbms after u click 'Refresh' button. for example, I use TOAD to do this because I connect to Oracle. The query parameter should be based on field value u entered in the 'Hibernate Mapping File' Form.
Try to see whether u enter the correct value for each field (e.q Schema Pattern; Table Pattern).

Hope this would help.

hi,
i am not using any application server... I am just a beginner so i am trying to do run my program without having any app server. I am successfully running the basic programs.. I am using Eclipse as my ide for writing my programs...

Now, i have a new doubt... how to execute queries.. i mean how to retrieve values from the table as a whole instead of providing a key value to the dao's load() method...

Thanks in advance for providing the solution...

I'm use find() method to query data.

or

use load() method

Hibernate is quite powerfull when speaking about querying. Please check the methods available in Session (as Session.find Sesion.iterate). Another options you got for querying are Query and Criteria.

hi,
i am using hibernate synchronizer in my eclipse to run my program...
So it generates dao's for processing and it writes its own code for creating sessions and and it ahve method like load(for select),save(for saving) and saveorUpdate(for updating) and delete methods...
but i couldn't find any find method on it...

But i heard that we write hql in my mapping file which will helps in executing the queries.. but i am not sure about it.

If there's a solution for this please notify me...
thanks a lot
