Problem with starting the SAP Gui

Hi Experts,

I am trying to install SAP IDES on Linux Machine. But the SAP Installation gui is not running.

Linux version is RHEL 6

Java version is 1.7.0_76

vi ~/.bash_profile is

export JAVA_HOME=/usr/java/jdk1.7.0_76

export PATH=$PATH:/usr/java/jdk1.7.0_76/bin

I can ping the sever itself by hostname. I can run xclock.

If I click on sapinst file(from the installation master folder) nothing is coming and if I run command ./sapinst from the directory it is showing below message guiengine: no GUI connected; waiting for a connection on host idessrv, port 21200 to continue with the installation

Though I am running it into the server machine. Please help to resolve it.

Thanks

Asad
