How to use existing tables of a database in liferay 6.1

[sudhansu rana，修改在11 年前。]

Hi,
I am new to liferay.
I have an existing database and some table names which are fixed and cannot be changed.
They don't follow any Namespace so i cannot use service builder.(like abc and not with namespace PR pr_abc)

Please advice how to use them either in service builder or spring+hibernate.

Thanks
Sudhansu

Hi Harish,

The sample seems to made in liferay 5.2.

Is there any sample for liferay 6.1.

Could you please guide me on this?

Hi Sudhansu,
If its compolsary to use separate database then you can follow the link send by Haris.
Otherwise if table value is fixed and won't change anymore, then you can copy those tables in liferay DB and then try with my below approach.

I didn't try with table but i tried with view.
In that i created sql view and then i created service with the same name of view and access the data from that view using service builder only.
But here you need to make sure that entity name should be same as view or table name.
Please try and put your feedback here.

Hello sudhansu rana,
For Connecting to a Database with Plugins SDK you can use above link given by Harish.
However,
If you existing table is going to use only once while importing data to liferay.
then you can do these steps:
make a portlet in liferay.
in this portlet read data from existing table using JDBC.
And, then using liferayservice add them to liferay as per requirement.

Thanks friends.
I could connect to different DB from portlet.
