Connect to the portal DB from an EJB

Hello all,

I'm writing an EJB for accessing the portal DB (SQL server).

I'm using the business methods of the EJB from a web dynpro application to connect/read/update the DB.

Before useing an EJB: I did everything in the web dynpro. it worked fine.

Now when writing the exact same code in an EJB I get the following exception when trying to connect (con = ds.getConnection()):

<b>I/O operation failed :</b>

Does anybody know what can be the problem?

Thanks, Adi.

Hi Adi,

if you could post the entire ejb source code I might be able to figure out what the problem is...also, is this EJB running on the same J2EE Engine as the portal?

Hi Jeff,

Sorry for the late response.

Apparently the problem was that I tried returning an object of type java.sql.Connection

which is not serializable.

Thanks for the good will, Adi.
