using the same example i want to change the total page count on every server call at client side using pagingToolbar.

Example: on very first request if the total record return is 100 and page size is set to 10 then screen will look return 1 to 10 and on second request i want to show 100 to 200 records then the page count should be from 11 to 20. How can i achieve this?

Is the class com.lk.remote.Person a JavaBean (http://en.wikipedia.org/wiki/JavaBean#JavaBean_...

> I don't have the constructor method JSONArray with a parameter boolean like you code
I'm using the JSON lib available on this page, http://www.json.org/java/index.html.

my jason is like

{ "totalPersons": 25, "persons": [ com.lk.remote.Person@1ad6b4b, com.lk.remote.Person@5f2db0, com.lk.remote.Person@b0a3f5, com.lk.remote.Person@dc41c5, com.lk.remote.Person@6214f5, com.lk.remote.Person@14e113b, com.lk.remote.Person@4d76b4, com.lk.remote.Person@1ac5f13, com.lk.remote.Person@195dd5b, com.lk.remote.Person@1f78b68]}

Why are not showing the attributes of the Account, it's showing the object.

and also

JSONArray jsonPersons = new JSONArray(persons, true);

I don't have the constructor method JSONArray with a parameter boolean like you code

Hi Rajesh,

Is the “total” attribute returned in your JSON correct? (the total field in the example I give is “totalPerons” – although that's a mis-spelling, it should be “totalPersons”). This attribute should be the total number of records in the listview, not just the current page.

Hi,
I tried above example , in my data base i have 21 records.But it's displaying only 15 records in my grid and next page and last page buttons are disabled.Could you help us to figure out the mistake done by me.

Rajesh

Unfortunately i put all the getters and setters methods. Do you have another idea about this problem? Maybe i am doing a mistake and i didn’t notice.

I notice the following:

JSONArray jsonPersons = new JSONArray(persons, true);

I don’t have the constructor method JSONArray with a parameter boolean like you code. In my code is:

JSONArray jsonAccounts= new JSONArray(accounts);

Other observation:

How is inserted the attribute class in JSON:

{
“class”: “class com._17od.servlets.Person”,
“dateOfBirth”: “2001-05-19″,
“firstname”: “Rebecca”,
“id”: 5,
“lastname”: “Taylor”
}

Thanks a lot

Could it be that your Account object isn't a javabean (with getters for each attribute)?

Hi, very good code.

I just have one doubt. I follow the steps and my json is like it:

{
"accounts": [
com.microcpd.mapp.server.Account@13b9fae,
com.microcpd.mapp.server.Account@1706da8,
com.microcpd.mapp.server.Account@2f356f],
"totalCounts": 3}

Why are not showing the attributes of the Account, it's showing the object.

Thanks a lot
