JCo Pool Connection filed. 'ashost' is missing

[Former Member]

Hello Experts,

I'm trying to connect to a SAP backend system using the JCo connection.

I've tyed with the standard connection, crating dinamically the connection and it works fine:

mConnection = JCO.createClient("001", // SAP client

"sap.user", // userid

"********", // password

"IT", // language

"ashost.domain.dom", // application server host name

"06"); // system number

mConnection.connect();

But if I try to use the JCo Destination, calling a Pool it doesn't work!

I get the error message "com.sap.mw.jco.JCO$Exception: (101) RFC_ERROR_PROGRAM: 'ashost' is missing".

I've tryed also to create a Pool dinamically, passing the same parameters of the working connection.. but the error message is the same..

Properties p = new Properties();

p.put("jco.client.ashost","ashost.domain.dom");

p.put("jco.client.client","001");

p.put("jco.client.user","sap.user");

p.put("jco.client.lang","IT");

p.put("jco.client.passwd","********");

p.put("jco.client.sysnr","06");

JCO.addClientPool(POOL_NAME, // pool name

5, // maximum number of connections

p); // properties

mConnection = JCO.getClient(POOL_NAME);

The system used by the Pool passes succesfully the Test Connection for the 'SAP Web AS Connection' ...

What can be the problem???

I misunderstood jco pool with jco destination...

Excuse me, but I need an explanation...

... when I write "mConnection = JCO.getClient(POOL_NAME);" I'm defining a new connection calling a POOL, but in my WebDynpro Console I've defined JCo Destinations element !

Which is the link between JCo Destination and Pool ??

I suppose that every JCo Destination has its own Pool..

But How can I choose, in my java code, which JCo Destination to use ???
