How to make this??

My code is:

try {

JCO.addClientPool(SID, 10, // Max. number of connections "300", // SAP client

"XXXXXXX",// userid

"XXXXXXX", // password

"EN", // language

"192.168.30.253",// host name

"00");

// Create a new repository

repository = JCO.createRepository("MYRepository", SID);

}

client [300] :

user [rfc-artear] :

password [XXXXXX] :

application host [192.168.30.253] :

jco.client.client : 300

jco.client.passwd : XXXXXX

jco.client.user : rfc-artear

Well did you first find out why you did get the timeout?

Could it be because the app server was not running?

Could the port not be open in the firewall?

Could the network path not be defined?

Wrong IP ?

Wrong port #?

Etc...

Can you access the SAP system using SAPGUI on those machines?

Enjoy
