create JCO Client in JSP

[Former Member]

Hi all,

I have the following problem: How I can create the JCOClient in the JSP? In the AbstractPortalContent I use this code

IJCOClientService clientService = (IJCOClientService request.getService("jcoclient");

IJCOClientPoolEntry poolEntry;

try

{

poolEntry = clientService.getJCOClientPoolEntry("SAP_cFolders", request);

}catch (Exception e)

{

response.write("Error obtaining connection: " + e);

return;

}

JCO.Client client = null;

client = poolEntry.getJCOClient();

client.connect();

In the JSP I don't able to create the JCO.Client.

Someone can help me?

Thanks in advance,

Stefano

Hi Vinod, thank you for your reply; it's very helpfull but how I can create the JCO client without passing the connection parameter(userID, password, SID...)? My problem consists of get information parameter of user connected to the portal. It's possible to get parameter connection from the poolManager in the JSP?

Thanks in advance,

Stefano

Hi Stefano,

You will have to pass the connection parameters. How ever you can get the logged in user id dynamically using the following method

portalRequest.getUser().getUserId().

If you have configued SSO between Portal and R/3, no need of passing the password it can be empty.

Also the best way of doing it would be that you keep all the connection parameters in IView properties file and pick it up from there.

Avoid JCOClient for EP6 and above. JCA is the recommended way to connect to SAP.
