New installation of webMethods B2Bi Server ver 6.1 on Red Ha

Can you provide detailed feedback for the following question. For resolution, it appears that the display env var should be set differently, for XWindows and thus the wM installer to run properly. If so, what do you think is the correct value for this env var?
thanking you
warm regards

After installing /usr/java/j2sdk1.4.2_10 folder with contents,
downloaded webMethodsInstaller65.zip for UNIX from http://advantage.webmethods.com,
using Console commands,
verified that /etc/inittab contains id:5:initdefault: for enabling XWindows,
typed ‘[root@localhost FileTransfer]# export DISPLAY=localhost:0.0’ and ENTER,
typed '[root@localhost Download]# java -Xmx512m -Xincgc -Djava.compiler=NONE -jar webMethodsInstaller65.zip
to get the following error
_X11TransSocketINETConnect: Can’t get address for localhost
Exception in thread “main” java.lang.InternalError: Can’t connect to X11 window server using ‘localhost:0.0’ as the value of the DISPLAY variable.

I tried the following which gets me past the previous issue, but brings me to the next issue: Is there an installer for Red Hat Linux IA64 OS, if so where can I find it?
thanking you
