I know some topics are not well covered here, but i will put my effort on that.
Refer to matter above, once you have successfully installed OER18.104.22.168 , you might get ERROR something called “Cannot deploy oer missing methods”
the fastest solution is to copy all jar from the Oracle DB installed folder C:\Oracle\Database\product\11.2.0\dbhome_1\jdbc\lib to oer-app lib folder C:\Oracle\Middleware\user_projects\applications\OSB_domain_1\applications\oer_22.214.171.124.0\oer-app\WEB-INF\lib
My Setup was
- ofm_oer_generic_126.96.36.199.0_disk1_1of1.zip which contains OER111160_generic.jar
- win32_11gR2_database for database
- oepe-wls-indigo-installer-188.8.131.52.0.201110211138-10.3.6-win32.exe for weblogic
