BW Java Split / PDF Error

Question

Recently my client had my team split out the java engine fromt he BW dual stack systems. They wanted to have single sign on  and could not do this with the abap system as their data source.
Rather than uninstalling the existing j2ee, we stopped it. I installed a new portal to host the j2ee processing and applications our client currently uses in the portal. I have found that in these previously dual stack systems port 8000 is redirecting to the j2ee engine, and then it shows as being unavailable because the j2ee engine is stopped.
How do we prevent the BW system from redirecting calls to j2ee? I want all port 8000 calls to be sent to abap exclusively. This has caused problems when I tried to setup adobe interactive forms, my destination back from the portal to BW always shows a http 503 error now because it is trying to call the j2ee not abap.
Thanks,

Note 1229586 indicates the profile parameters all need to be cleaned out for j2ee after a split. The parameter icm/HTTP/j2ee_0 was still set.
icm/HTTP/j2ee_0  PREFIX=/,HOST=localhost,CONN=0-500,PORT=5$$00 - removing this from the SAP profile and restarting the ICM will resolve the issue.
Prior to to removal http calls to port 8000 always come back with:
