Install JDev 18.104.22.168
Run integrated weblogic.
Now install just weblogic 10.3.6 I used the generic installer.
java -jar -D64 -Xmx1024M wls1036_generic.jar
Next > Select Create new MiddlewareHome and enter a value > Next > Typical > Next
Now select your JDK and click Next * 3
Select 9.0 or Higher
Find your integrated domain [usually under C:\Users\[username]\AppData\Roaming\JDeveloper\system22.214.171.124.38.62.29\DefaultDomain]
NOTE: On windows I had to make this folder ! read only but this is not recommended. If you don't want to do this Install your integrated server in a different location
Once the Installer has finished backup setDomainEnv.cmd then copy setDomainEnv.cmd.back to setDomainEnv.cmd and edit the line:
set WL_HOME=... and make it set WL_HOME=C:\Dev\Oracle\Weblogic_10.3.6\wlserver_10.3
The location for these files is:
