If you read through the stack trace it tells you what is wrong:

DataSource property serverName must be specified.

[sabr sabars]

i think the problem is Unable to get a PooledConnection from the DataSource.

please tell me how to solve this problem

[sabr sabars]

Then , How can i solve this problem ? pls help me

[Carol Enderlin]

You could start by providing more details. Are you using a datasource/connection pool configured in your code or in an application server's "console" or similar? Post some details about that, including a code snippet showing how you are trying get your connection.

If you're configuring a datasource in your code to get a connection from, are you giving the serverName? Just a wild guess.

these are more information that can assist you to help me :

pls tell me what's the problem ? and how i can solve it

[sabr sabars]

pls tell me what's the problem? and how can i solve it ?

[Carol Enderlin]

Your code appears to be indirectly asking for a connection from a datasource with a particular name, "jdbc/DBDatasource" from your stack trace.

So, is the datasource and and associated connection pool configured in websphere? It has to be configured somewhere. It won't just find a database by magic.

You mentioned "3-i test my application in the test unit "...is that a particular product?

Did you try googling on your main errors? I don't use websphere so I don't know the obvious questions to ask you.

argh! How many posts do you have going on this topic!?!?!?! I see Shailesh is trying to help you over on this post, Topic: could not connect to my sqlserver by datasource by websphere

Please only post once on a topic, you are wasting people's time. You could try looking at the websphere documentation.
