A question on JDeveloper & ADF OTN forum cought my attention. A user wanted to use a method of the Apache Commons-IO library named FileUtils.getTempDiretory() but got an error when he tried to use code completion or when he tried to compile the code. The problem was that the compiler (or code completion) did not pick up the right java class from the library even as it was installed in the project a library.
As the original code used belongs to one of my samples I was interested in finding a reason for this behavior as I could see no obvious reason for this behavior.

An inspection of a provided test case quickly revealed the problem and a solution was found too. This blog is about the problem and the solution to it. Lets start with building a test case: Read the complete article here.
