Weblogic: Defeating the Unable to load performance pack 64bit

JDeveloper 11.1.2, Windows7, 64bit

Unable to load performance pack. Using Java I/O instead. Please ensure that wlntio.dll is in blah....

I get this error message on my local windows machine and it annoys the hell out of me so I had to fix it.

Step 1) Download the generic install version of Jdev (jar version)
Step 2) Install this with a 64 bit vm -- cmd prompt java -server -jar jdevstudio11115install.jar (I used the -server parameter I dont know if this makes a difference but I dont feel like trying without it.)
Step 3 ) make sure you use a 64bit jvm in the install



Worked for me.

ADF: LOV Description instead of code

I keep on forgetting how to do this so this is a note to self in terms I understand (ie pictures): Add the related entiy object to yours (in the example we are adding RegionEO(list of values) to CountryEO) Now add the RegionName field from the EO and a transient attribute (I named mine RegionNameLOV) Make the transient attribute updateable and base it on the expression RegionName (the description you wish to display) Add a list of values to RegionNameLOV and map BOTH key to parent fk (region id here) AND RegionName to your transient coulmn (RegionNameLOV).  Map the transient as an Input text with List of Values. Then just drag the lov item onto the page (RegionNameLOV)
