If you are installing SOA suite 11g from scratch, oepe-helios-all-in-one-22.214.171.124.1.20101 is not recognized by the OSB installer. This is the case on both windows and linux 64-bit. However it will recognize oepe-helios-all-in-one-126.96.36.199.0.201007221419 and no, layering 188.8.131.52.1 over the top of 184.108.40.206.0 does not fix this.
I guess once OSB is installed with 220.127.116.11.0 present, one might then just layer 18.104.22.168.1 over the top at the point and all would be OK - that's assuming that OSB install doesn't copy any 22.214.171.124.0 libraries into another location when it does it's install. Can anyone comment on this? I guess I can find this out by trial and error but it would be good to know if someone else has already been there.
I would recommend installing OSB with the version of OEPE that ships in that installer (126.96.36.199.0). Then once everything is working, have Eclipse search for updates (Help -> Check For Updates...). That will pull down and install OEPE 188.8.131.52.1 if OSB plugins are compatible with it, which they should be.
Yes Konstantin's reccomendation should work. Also, there is a .link file in the dropins folder of oepe which points to the OSB eclipse plugins. Please make sure that file is present after 184.108.40.206.1 is installed through the update mechanism
Please let us know if OEPE 220.127.116.11.0 available, I tried installing lower version of OEPE (OEPE 18.104.22.168) but still have the same issue with newer OSB 22.214.171.124 generic installer! now i am struck not having a OEPE IDE equivalent for OSB 126.96.36.199
