Right - I installed V24032-01 which is EnterpriseOne 9.0.2 V2. Be careful, this now uses the Oracle Universal Installer ! It does have 8.98.3 tools release bundled in it, so after installing, I upgraded the tools release to 8.98.4.3 using the deployment server download (unzip all the system.cab files and replace system).
You must ensure that the tnsnames.ora exists in the j2ee classes path correctly, together with a correctly formatted jas.ini and jdbc.ini - that is the biggest issue in getting the JAS server up and running.
However, it all works pretty well. I wasn't sure if I even had 9.0.2 running (when you click "help / about" it still reports 9.0 !) - but the clue is that under the EnterpriseOne Menus you'll see a new "Apparel" menu - if you see that, then you're running 9.0.2.
I'm struggling with getting the JDeveloper working on standalone now - evidently, 11g is supposed to be supported - but OMW doesn't recognize it when I install it to the standard c:\oracle\middleware path - so I'm now trying to install it to C:\JDEV just in case (!). I have a SR open with Oracle on this issue.
Lastly, I'm installing BI Publisher Standalone Server on the standalone as well - I really want every facet installed on this little beast ! Maybe some of the Everest demo software too !
