Hi Manivannan ,

We wont be able to help you futher unless you can confirm the link you are trying to access .

There is lot of ambiguity with your webdispatcher profile anyways [ As you are  using the same URL filters and same webdispatcher ports ]

Read the following link  and  you should be able to fix the issue for yourself

Hi Manu,

Thanks ,

I have Installed one web dispatcher and to needs attach with 2 Java systems (PO & EP) , Only PO is working , and but EP is not working.

The EP initial logon page username & password is not accepted , the EP Page is not redirecting to the EP server.

Hi,

You have conflicting system selection criteria:

wdisp/system_0 = SID=COD, MSHOST=APP1.com, MSPORT=8104, SRCURL=/nwa;/logon;/nwa
wdisp/system_1 = SID=CED, MSHOST=APP2.com, MSPORT=8101, SRCURL=/irj;/logon;/nwa;/webdynpro

---> "/logon" can go to either system

Read the documentation about the wdisp/system - SAP Web Dispatcher - SAP Library parameters, specially the sections about SRCSRV and SRCURL.

Hi Isaias,

Thanks for your reply.I am not getting exactly what you are mentioned.can you please elaborate. so that it is very helpful to me.

wdisp/system_0 = SID=COD, MSHOST=APP1.com, MSPORT=8104, SRCURL=/nwa;/logon;/nwa

wdisp/system_1 = SID=CED, MSHOST=APP2.com, MSPORT=8101, SRCURL=/irj;/logon;/nwa;/webdynpro

Hi Manivannan ,

[ As per my understanding ]

The external applications are connecting to your system using the port of your webdisapatcher  ( http :8100 and https :443 )

Since your webdiaptcher operates only on one port ( ie 443 and 8100 )  , there will be ambiguity as you have /logon and /nwa common in both profiles  ( check below )

wdisp/system_0 = SID=COD, MSHOST=APP1.com, MSPORT=8104, SRCURL=/nwa;/logon;/nwa

wdisp/system_1 = SID=CED, MSHOST=APP2.com, MSPORT=8101, SRCURL=/irj;/logon;/nwa;/webdynpro

One way to resolve this is ,  [ But then the webdispatcher  link will change for each system  ]

The idea will be to add more ports to the webdisaptcher and use SRCSRV instead of SRCURL .

Please read the following link

One Web Dispatcher, Two Systems: Configuration Example - SAP Web Dispatcher - SAP Library

Thanks ,

Hi Mani ,

just a hunch , Is there a newline in the profile

wdisp/system_1 = SID=CED, MSHOST=APP2.com, MSPORT=8101, SRCURL=/irj;/logon;/nwa;/webdynpro

Thanks ,

Hi,

Yes , that is new line.

[manumohandas82]

Hi Manivannan ,

To confirm on anything you need to provide the follwoing

1 ) The full link you are accessing

2 ) Check the webdispatcher profile using

sapwebdisp -check

Believe there should be no new line , secondly dont know why you are using wdisp/system_conflict_resolution = 2 [ It should be one as u are only controlling using URL prefixes  ]  and last you have not configured for the link "/favicon.ico"in either filters .

Thanks ,

Manu

Hi Jayaraman,

First of all there will be no new line  for SRCURL , it will be a part of wdisp/system_1

Secondly,Replace the below parameter

icm/HTTP/redirect_2 = PREFIX=/, FROM=/nwa,TO=/nwa, PORT=443

with

icm/HTTP/redirect_2 = PREFIX=/irj, FROM=/nwa,TO=/nwa, PORT=443

Let us know the status.
