I'm implemeting a small application with using JBoss Application server. To keep connection between server and the Db I use Entity manager object.
In my bean definition class i use following code for that

Then in save ,delete ,retrieve methods just use entityManager and call Entity Manager class methods.But I don't have any idea why we don't initialize this entityManager

How we achieve our behaviors without initializing?

I use guava cache in my appliation which was written in a hibernate platform. The problem is my cache doesn't work well when loading the data. It doesn't update quickly when I delete or add a new data.

and this is the way I load data to the server side,

Also I don't use the cache in data saving or deletion. Can some one explain me what is the reson for this issue? Is it a problem of guava cache?

Hey ,
I found the problem of here.In my method I declared column value as the row value (fixValue). So then method in my rendering class gets object value as that fixValue and then get some strings and set that value in the column and the tool tip too.

So I can't sort that column according to the string value here.Because it returns all the row value. So whta Can I do here is set the relevant string in the (column no 3) and then pass that string to renderer class.then just set tool tip only.No need of set text here.Because I set value in model class

Just these 3 lines. Simple !!!
