IB Java API example connection problem trough IB Gateway

Halo
I have no problem to connect the java API example (TestJavaClient) using Netbeans if my TWS Workstation is running. However, I cannot connect trough IB gateway. The IB gateway seems to be connected, but Java example does not work.

 

do you give a temp guest account on you machine. I will do it for you

 

IB Gateway API port needs to match the one that you are using to connect.

 

Thank you.. I found the port in IB Gateway is different.., 4001
also the ID must be set. It works now. thank
