Do you have any suggestion to solve such problem?
and in DMZ1, may I telnet Core 8111?
Thanks a lot!

hi,Srihari,
We check the connection what you mentioned.DMZ1 is OK for Core and Port 8111.We open 8111 in Core as telnet port too. I try to use such command:
dga114:cwiadm 9> sapwebdisp -bootstrap
SAP Web Dispatcher Bootstrap
============================
This bootstrap will perform the following steps:
1. create profile file "sapwebdisp.pfl"for SAP Web Dispatcher (if not already existing)
2. create user for web based administration in file "icmauth.txt"(if not already exisiting)
3. start SAP Web Dispatcher with the created profile
After the bootstrap you can use the web based administration
Generating Profile "sapwebdisp.pfl"
Hostname of Message Server (rdisp/mshost): dga107
HTTP Port of Message Server (ms/http_port): 8111
Checking connection to message server...
ERROR: Illegal data received (no HTTP?) -
please check that 8111 is really the HTTP port of the Message Server
and I think the parameter doesn't matter about this problem, does it?
Thanks for your reply.
Best Regards,
Lily
