Could not connect to host localhost on port 21212

Hello,

I am trying to have my first experience with SAP and am trying to install "SAP NetWeaver AS ABAP 7.03 SP04 64-bit Trial, 3.912 GB". However I receive the following log error in a SAP delivery tool:

Error while connecting to communication partner - see preceding messages.

Could not connect to host localhost on port 21212.

java.net.ConnectException: Connection timed out: connect

java.net.ConnectException: Connection timed out: connect

21212 is being used by a java.exe. I close it and also close all SAP instances in the windows task manager and restart the installation process but I get the same message again. I also read other threads about a same issue, but could n't find out exactly what the cause is. 

Could any body know about this issue?

PS: I am new to SAP

    Hi,

    Aug 25, 2014 4:51:11 AM [Info]: Starting HTTP server listening on port 4239 ...

    Aug 25, 2014 4:51:11 AM [Error]: java.net.BindException: Address already in use: JVM_Bind

    Check if this port 4239 is nor occupied by some other process.  If yes,  then kill that service.

    Refer

    Or use another port number.

    Regards
