Thanks kalai for responding.
Here is the process i followed.
1) I have downloaded & installed Apache HTTP Server 2.0 from http://httpd.apache.org/download.cgi#apache20
2) I copied mod_wl128_20.so, mod_wl_20.so files from weblogic to apache modules folder.
3) I added the following code at the end of httpd.conf file of Apache2.0
4) In the same httpd.conf file, i have changed the Server port. Thats all.
One interesting thing that i observed is the pages is loaded perfectly fine in IE (8), but in firefox(3.5) they are not loading properly.
I think i have missed some other important configuration. Please help me.
